Power supplying unit 160 can supply power necessary for the operation of each constructing element by introducing power from internal or external source by the control of the controller 120.
The input/output module 200 can provide color information reflecting information related to the operating state of the electronic device 100. The input/output module 200 can also provide color information reflecting information related to the operating state of the electronic device 100 changed by the external input information.
The input/output module 200 can include a light emitting module 300, a light guiding module 400 and a touch sensing module 500. The light emitting module 300 can be implemented by single light emitting module that can emit light of one or multiple colors, or multiple light emitting modules that can emit light of colors which are different among the modules. At least one of intensity and color of the light emitted from at least one of the light emitting module 300 can be changed by the control of the controller 120.
The light guiding module 400 performs the function of guiding lights emitted from the light emitting module 300. The light guiding module 400 can include one or more of light guiding passages which guide lights emitted from the corresponding light emitting module of the multiple light emitting module and which include light penetrating area on at least part thereof. Also, the light guiding module 400 can mix lights of different colors emitted from multiple light emitting modules, and include at least one light guiding passage including at least part of light penetrating area.
The touch sensing module 500 can detect at least one of direct touch and near field touch, and transmit detection result to the controller 120. Then, the controller 120 can control at least one of color and intensity of the light emitted from at least one of the light emitting module 300 according to the touch sensing result. The controller 120 can also control at least one of color and intensity of the light emitted from the light emitting module 300 based on the number, intensity, area size or duration of the touch received through the touch sensing module 500.
The touch sensing module 500 can be a part of a user input unit (not illustrated). The user input unit generates input data by a user for controlling the operation of the electronic device 100. The user input unit can comprise key pad, dome switch, touch pad (resistive/capacitive), jog wheel, jog switch, etc., in addition to above mentioned touch sensing module 500.
The operation of information input and output through the input/output module 200 of the electronic device 100 according to the present invention and the construction of the electronic device 100 have been briefly described with reference to Figs. 1 and 2. The function of information input and output implemented by the input/output module 200 according to the embodiment of the present invention will now be described in more detail with reference to Fig. 3 Fig. 41.
Fig. 3 shows plane views and cross-sectional views of various examples of the input/output modules included in the electronic device of the present invention. It should be noted that although the light emitting modules 310, 320 illustrated in Fig. 3 can be implemented by emitting diodes each of which emits lights of corresponding colors, the scope of the present invention is not limited to this implementation.
First, Fig. 3 (a) is a plane view of the input/output module 200 which includes one light emitting module 310 emitting red light. Referring to Fig. 3 (a), the input/output module 200 includes a light guiding module 400 which guides the light emitted from the light emitting module 310. The light guiding module 400 includes a light penetrating area 410 through which the red light emitted from the light emitting module 310 is penetrated. Various information related to the operation of the electronic device 100 can be provided to a user through the light penetrating through the light penetrating area 410. The light penetrating area 410 will described in more detail below with reference te Fig. 3 (d).
Assume, for example, that the input/output module 200 illustrated in Fig. 3 (a) is set to represent the volume of the audio signal output from the audio output module 140 of the electronic device 100. In this case, the controller 120 can control the light emitting module 410 so that the red light emitted from the light emitting module 410 is guided by the distance corresponding to the volume of the audio signal, and provided to the user through the light penetrating area 410 of the light guiding module 400.
Fig. 3 (b) is a plane view of the input/output module 200 including the first light emitting module 310 which emits red light, and the second light emitting module 320 which emits green light. Fig. 3 (c) is a cross-sectional view of the input/output module 200 illustrated in Fig. 3 (b). Referring to Fig. 3 (b) and (c), it can be recognized that the input/output module 200 is arranged so that the lights emitted from the first light emitting module 310 and the second light emitting module 320 are guided in the opposite direction. Also, referring to Fig. 3 (c), light penetrating area 410 for enabling part of light to penetrate is formed on the part of the light guiding passage 405 which is a space for guiding light.
The red light emitted from the first light emitting module 310 and the green light emitted from the second light emitting module 320 can be mixed by the light guiding module 400. Therefore, the red light, green light and the mixed light can be provided to a user through the light penetrating area 410 in the light guiding module 400.
Assume that the input/output module 200 illustrated in Fig. 3 (b) is set so that the center of mixed light, which is yellowish light by mixing the red light and the green light, represents the volume of the audio signal output through the audio output module 140 of the electronic device 100. In this case, the controller 120 controls the electric signal introduced into the first light emitting module 310 and second light emitting module 320 so that the center of the mixed light is located at the location corresponding to the volume of the audio signal.
In the input/output module 200 of Fig. 3 (a) and (b), unlike Fig. 3 (c), the touch sensing pad 510 that can be included in the input/output module 200 is not illustrated for the purpose of only explaining light emitting characteristics. The touch sensing pad 510 is part of the touch sensing module 500 illustrated in Fig. 1, and can detect both direct and indirect touch.
When touch on specific location of the touch sensing pad 510 is detected, the controller 120 of the electronic device 100 can provide feedback of the touch on specific location itself to the user through the input/output module 200. For example, the input/output module 200 in Fig. 3 (a) can control the electric signal introduced into the light emitting module 310 so that the red light emitted from the light emitting module 310 is guided to the specific location. For example, the input/output module 200 in Fig 3 (b) can control the electric signal introduced into the first light emitting module 310 and the second light emitting module 320 so that the center of the mixed light is located at the specific location.
It is possible to set the touch on specific region of the touch sensing pad 510 to request of specific operation information of the electronic device 100. In this case, when touch on the specific region is detected, the controller 120 can control the input/output module 200 in Fig. 3 (a) and (b) so that the information corresponding to the specific operation information is provided to the user.
Fig. 3 (d) shows the mechanism in which the guided light is provided to the user from the light guiding passage 405 through penetrating the light penetrating area 410 in the light guiding module 400. Referring to Fig. 3 (d), it can be seen that the lower part of the light guiding module 400 includes multiple fine patterns 410A, 410B, 410C. If the fine patterns 410A, 410B, 410C are not present, the light emitted from the light emitting module is guided to the end of the light guiding module 400 through total reflection without penetrating the light penetrating area 410.
However, part of the light which is emitted from the light emitting module and reaches the fine patterns 410A, 410B, 410C can transmitted to the user through scattered reflection by penetrating the light penetrating area 410. The arrows in Fig. 3 (d) indicate the flow of light which is scattered by the fine patterns and penetrates the light penetrating area 410.
While the amount of light which is provided to the user by penetrating the light penetrating area 410 increases as the density of fine patterns included in the lower part of the light guiding module 400 increases, the amount of light which is provided to the user by penetrating the light penetrating area 410 decreases as the distance from the light emitting module increases. Also, if the intensity of the light emitted from the light emitting module is lower than certain amount, light can be provided to the user by penetrating the region of the light penetrating area 410 which is near to the light emitting module. Therefore, it is necessary to decide the density of the fine patterns included in the light guiding module 400 in consideration of the characteristics described above and the operational characteristics of the electronic device including the light guiding module 400.
Also, specific shapes can be formed by the light penetrating the light penetrating area 410 according to the arrangement of the fine patterns in the light guiding module 400. For example, the shape of specific characters or marks can be formed by the light penetrating the light penetrating area 410 by arranging the fine patterns in the shape of specific characters or marks.
It is assumed in the present specification that the light emitted from the light emitting module is scattered, as described above, by the fine patterns included in the light guiding module and penetrates the light penetrating area. The scope of the present invention, however, is not limited to this arrangement. Also, fine patterns included in the light guiding module will not be illustrated in following drawings unless specifically necessary.
Fig. 4 illustrates another example of the input/output module 200 included in the electronic device 100 of the present invention. It may be noted that the input/output module 200 illustrated in Fig. 4 includes multiple emitting layers arranged on the same plane.
Referring to Fig. 4(a), it can be seen that the input/output module 200 includes a plurality of light emitting modules 310, 320, 330, 340, and a pair of light guiding passages 405, 415 for guiding the lights emitted from the pair of the light emitting module corresponding to the plurality of light emitting modules 310, 320, 330, 340 in the opposite direction.
Part of each of the light guiding passages 405, 415 includes light penetrating areas 410, 420, and the light representing the information related to the operation of the electronic device 100 can be provided to the user through the light penetrating area 410, 420. For example, the first emitting layer including the first light emitting module pair 310, 320 and the first light guiding passage 405 can be used to provide the information related to the first operation of the electronic device 100, and the second emitting layer including the second light emitting module pair 330, 340 and the second light guiding passage 415 can be used to provide the information related to the second operation of the electronic device 100.
Referring to Fig. 4 (b), the input/output module 200 includes the first emitting layer including the first light emitting module pair 310, 320 and the first light guiding passage 405, the second emitting layer including the second light emitting module pair 330, 340 and the second light guiding passage 415, and the third emitting layer including the third light emitting module pair 350, 360 and the third light guiding passage 425.
Although the shape and arrangement of the light penetrating area 410, 420 in the first emitting layer and the second emitting layer is different, the color of the light used to provide information and the emitting position relative to the light guiding passage is identical. Therefore, the first emitting layer can be used to represent increase in the amount of the same information, and the second emitting layer can be used to represent decrease in the amount of the same information. Then, the user can recognize the operating state information of the electronic device 100 intuitively only by the color information provided by the input/output module 200.
Meanwhile, in the case where the color and emitting location of the color used in the first emitting layer and the second emitting layer is different, the first emitting layer and the second emitting layer can be used to provide information which is contrary to each other. For example, the first emitting layer can be used to represent booting process, and the second emitting layer can be used to represent the process of powering off the electronic device 100. Then, the user can recognize the operating state of the electronic device 100 intuitively only by the color information provided by the input/output module 200.
The third emitting layer can represent the information provided through the first and the second emitting layers by using the light penetrating area 430 through which the light or combination of lights emitted from the light emitting module pair 350, 360 passes, or the location of the touch for controlling the operation of the electronic device 100. In this process, it is assumed that the input/output module 200 illustrated in the Fig. 4 (b) also includes the touch sensing pad (not illustrated).
For example, when the user touches the portion of 'POWER' in the light penetrating area 430 of the third emitting layer, the controller 120 of the electronic device 100 can supply power to the electronic device 100 or stop supplying power to the electronic device 100 in response to the touch.
Fig. 5 conceptually explains the process for controlling the operation of the electronic device 100 by using the input/output module 200 of the electronic device 100 of the present invention, and the process for providing information related to the operation of the electronic device 100. It may be noted that only the constructions of the light emitting module 300 and touch sensing module 500 of the electronic device 100, which is necessary to briefly explain the above description, are illustrated in Fig. 5.
First, the process in which the electronic device 100 simply provides the information related to the electronic device 100 by using the input/output module 200 will be described. The controller 120 of the electronic device 100 transmits the electric signal (i.e., the control signal or drive signal) generated based on the information representing the operating state of the electronic device 100 to the LED controller 305. In other words, it is assumed that, in the electronic device 100 according to the present invention in Fig. 5, the light emitting module 300 includes LED module, and the LED module 300 is controlled by the LED controller 305.
As illustrated in Fig. 5, I2C (Inter-Integrated Circuit), RS232 (Recommended Standard 232), SPI (Serial Peripheral Interface), etc. can be used as the interface between the controller 120 and the LED controller 305. The LED controller 305, upon receiving the control signal, transmits the control signal to the LED pair 310, 320 to control lighting of the LED pair 310, 320.
Then, the light emitted from the LED pair 310, 320 is guided through the light guiding passage 405, and part of the emitted light is provided to the user by penetrating the light penetrating area 410 of the light guiding module 400. In this case, the information provided by the light penetrating the light penetrating area 410 can be the information related to the electronic device 100.
Also, the controller 120 can also transmit the control signal generated based on the information representing the operating state of the electronic device 100 in response to the information on the location or movement of the touch received through the touch sensing pad 510 to the LED controller 305.
Secondly, an example of the process in which the operating state of the electronic device 100 is controlled by the touch information received through the touch sensing pad 510. When user's touch on the touch sensing pad 510 is detected, the touch controller 520 transmits the information on the location and movement of the user's touch to the controller 120.
Then, the controller 120 can control the operating state of the electronic device 100 based on the information on the location and movement of the user's touch. Also, the controller 120 can transmit the control signal reflecting the result of control on the operating state to the LED controller 305, and provide the result of control on the operating state to the user through the input/output module 200.
Fig. 6 illustrates the example where the light emitting shape of the input/output module 200 including the first LED emitting red light and the second LED emitting blue light is changed by user's touch. It should be noted that mixing of emitted lights is not considered in Fig. 6 which conceptually illustrates that the intensity of emitted light can be controlled by the user's touch.
Referring to Fig. 6 (a) through Fig. 6 (e), it can be seen that, as a user moves the touch from left to right, the intensity of red light emitted from the first LED increases. Referring to Fig. 6 (f) through Fig. 6 (i), it can be seen that, as a user moves the touch from right to left from the state shown in Fig. 6 (e), the intensity of red light emitted from the first LED decreases while the intensity of blue light emitted from the second LED increases. The method for controlling the emitting shape in the input/output module 200 illustrated in Fig. 6 is just one embodiment of the present invention, and does not limit the scope of the present invention into the above method.
Fig. 7 illustrates the movement of the mixing area of light emitted from the light emitting module pair 310, 320 as the touch on the input/output module 200 moves.
Fig. 8 conceptually illustrates the mechanism of moving the mixing area of light emitted from the light emitting module pair 310, 320 as illustrated in Fig. 7.
Referring to Fig. 7 (a), the mixing area of light emitted from the light emitting module pair 310, 320 is seen to be formed on a certain area centering around the location A when a user touches the location A of the input/output module 200.
Referring to Fig. 8 (a), it can be seen that, upon receiving touch information on the location A by a user, the controller 120 of the electronic device 100 according to the present invention controls the intensity of lights emitted from the first light emitting module 310 and second light emitting module 320 so that the mixing area of the red light emitted from the first light emitting module 310 and the green light emitted from the second light emitting module 320 is formed centering around the location.
Referring to Fig. 7 (a) and (b), it can be seen that, as a user moves the touch on the input/output module 200 from the location A to the location B, the center of the mixing area of lights emitted from the light emitting module pair 310, 320 moves from the location A to the location B.
Referring to Fig. 8 (b), it can be seen that, as a user moves the touch on the input/output module 200 from the location A to the location B, the controller 120 increases the intensity of red light emitted from the first light emitting module 310 so that the center of the mixing area of lights emitted from the light emitting module pair 310, 320 moves from the location A to the location B.
Referring to Fig. 7 (a) and (c), it can be seen that, as a user moves the touch on the input/output module 200 from the location A to the location C, the center of the mixing area of lights emitted from the light emitting module pair 310, 320 moves from the location A to the location C.
Referring to Fig. 8 (c), it can be seen that, as a user moves the touch on the input/output module 200 from the location A to the location C, the controller 120 increases the intensity of green light emitted from the second light emitting module 320 so that the center of the mixing area of lights emitted from the light emitting module pair 310, 320 moves from the location A to the location C.
The method of controlling the shape of emitted light from the input/output module 200 illustrated in Figs. 7 and 8 is just one embodiment of the present invention, and does not limit the scope of the present invention into the above method.
Fig. 9 illustrates another example of the input/output module 200 of the electronic device 100 according to the present invention. The input/output module 200 illustrated in Fig. 9 adopts multi-layer structure in which a plurality of layers are arranged on different surfaces which are separated perpendicularly, rather than being arranged on the same surface like the examples described above.
Referring to Fig. 9, it can be seen that the input/output module 200 includes the first emitting layer which includes a touch sensing pad 510, the first light emitting device pair 310, 320 and the first light guiding passage 400-1, and the second emitting layer which is arranged under the first emitting layer and includes the second light emitting device pair 330, 340 and the second light guiding passage 400-2.
The light emitted from the first light emitting device pair 310, 320 is guided through the first light guiding passage 400-1, and the guided light passes through the light penetrating area 435-1 formed on the first part (PART 1) and then provided to the user. In other words, while the first part (PART 1) includes fine patterns arranged in it to cause scattered reflection of the guided lights, the second part (PART 2) does not include fine patterns so that the lights are merely guided through total reflection without scattering. This is the same in the light guiding passage 400-1 of Fig. 10.
The first light guiding passage 400-1 is preferably transparent or translucent. The reason is that the lights passing through the light penetrating area 435-2 of the second emitting layer should be provided to the user. Also, at least the light penetrating area of the second light guiding passage 400-2 should be transparent or translucent.
The touch sensing pad 510 can also be divided into a first touch sensing area 510-1 corresponding to the first emitting layer and a second touch sensing area 510-2 corresponding to the second emitting layer, as illustrated in Fig. 9. For example, the touch on the first touch sensing area 510-1 can be allocated to receive the touch for selecting the control function represented by the light penetrating area 435-1 of the first emitting layer, and the second touch sensing area 510-2 can be allocated to receive the touch to perform the control function selected above.
Fig. 10 illustrates another example of the input/output module 200 of the electronic device 100 according to the present invention. It can be also seen that a pair of emitting layers are arranged on the different surfaces which are separated perpendicularly in the input/output module 200 illustrated in the 10.
Referring to Fig. 10, it can be seen that the input/output module 200 includes the first emitting layer which includes a touch sensing pad 510, the first light emitting device pair 310, 320, and the first light guiding passage 400-1, and the second emitting layer which is arranged under the first emitting layer and includes the second light emitting device pair 330, 340 and the second light guiding passage 400-2.
As described with reference to Fig. 9, the light emitted from the first light emitting device pair 310 of the first emitting layer of the input/output module 200 illustrated in Fig. 10 is guided through the light guiding passage 400-1, and part of the guided light can be provided to the user by passing through the light penetrating area 440-1 formed on the first part (PART 1). The first light guiding passage 400-1 is preferably transparent or translucent since the light passing through the light penetrating area 440-2 of the second emitting layer should be provided to the user. Also, at least the light penetrating area of the second light guiding passage 400-2 should be transparent or translucent.
The patterns representing the functions that can be controlled by the input/output module 200 is represented on the light penetrating area 440-1 of the first light guiding passage 400-1 of the first emitting layer of the input/output module 200 illustrated in Fig. 10. In this case, it is preferable that the patterns have different transmittance than the transmittance of the light penetrating area 440-1. The patterns can be represented by, for example, nontransparent material. In this way, the user can easily recognize the portion of patterns when light passes through the light penetrating area 440-1.
Fig. 11 is an exploded perspective view of the input/output module 200 of the electronic device 100 according to another embodiment of the present invention. In Fig. 11, the input/output module 200 illustrated in the figure represents input/output module 200 having multi-layer structure with three emitting layers laminated.
Referring to Fig. 11, the input/output module 200 includes a case 210, a PCB (Printed Circuit Board), a light emitting module 300A, 300B mounted on the PCB, a sensor pattern 500A mounted on the PCB, a light guiding module 400 including the first, second and third light guiding passage 400-1, 400-2, 400-3.
It can be seen that the case 210 includes bumps 210A, 210B which enable the second and third light guiding passages 400-2, 400-3 to be arranged at the level corresponding to the height of the light emitting device pair mounted on the PCB after the PCB has been installed on the case 210. Although not illustrated in the figure, additional bumps corresponding to the bumps 210A, 210B are formed on the inner surface of the case 210.
Although not specifically illustrated in the figure, the PCB can include various devices for driving the light emitting module 300A, 300B and wires connecting the light emitting module 300A, 300B and the various devices. The PCB can also include various devices for driving the sensor patterns 500A for detecting user's touch and wires connecting the sensor patterns 500A and the various devices.
The first light guiding passage 400-1 guides the light emitted from the two pairs of light emitting devices with the lowest heights of mounted PCBs among the light emitting devices included in the light emitting module 300A, 300B, the second light guiding passage 400-2 guides the light emitted from the two pairs of light emitting devices with the middle heights of mounted PCBs among the light emitting devices included in the light emitting module 300A, 300B, and the third light guiding passage 400-3 can guide the light emitted from the two pairs of light emitting devices with the highest heights of mounted PCBs among the light emitting devices included in the light emitting module 300A, 300B.
Also, it is preferable that at least the second and third light guiding passages 400-2, 400-3 of the first, second and third light guiding passages 400-1, 400-2, 400-3 are made of transparent or translucent material. The reason is that the light which has passed through the light penetrating area of the light guiding passage below the second and third light guiding passages 400-2, 400-3 should be provided to the user by penetrating the second and third light guiding passages 400-2, 400-3. It may be noted that light penetrating areas that can be formed on part of each of the first, second and third light guiding passages 400-1, 400-2, 400-3 are not illustrated in Fig. 11. Also at least the light penetrating area of the first light guiding passage 410 in the first light guiding passage 400-1 should be transparent or translucent.
Fig. 12 is a detailed view of the case 210 of the input/output module 200 illustrated in Fig. 11. Referring to Fig. 12, it can be seen that the inner surface of the case 210 includes additional bumps 210B corresponding to the bumps illustrated in Fig. 11.
Fig. 13 illustrates the combined state of the input/output module 200 illustrated in Fig. 11. It may be noted that Fig. 13 shows the cross-sectional view of the input/output module 200 cut along the line A-A' of Fig. 12 in the state where the PCB and the light guiding module 400 are combined with the case 210.
Referring to Fig. 13, it can be seen that the first light guiding passage 400-1 is layered on the PCB, and the second light guiding passage 400-2 and the third light guiding passage 400-3 are arranged on the bumps 210A, 210C formed on the case 210 and sequentially layered on the first light guiding passage 400-1.
Fig. 14 is an enlarged view of the light emitting module 310A, 310B and sensor pattern 500A mounted on the PCB illustrated in Fig. 11. Referring to Fig. 14, it can be seen that one side 300B of the light emitting module 300A, 300B mounted on the PCB includes a light emitting device pair 300B-1 which emits light to the first light guiding passage 400-1, a light emitting device pair 300B-2 which emits light to the second light guiding passage 400-2, and a light emitting device pair 300B-3 which emits light to the third light guiding passage 400-3. The other side 300A of the light emitting module 300A, 300B includes a light emitting device pair corresponding to the light emitting device pair.
Fig. 15 illustrates that the first light guiding passage 400-1 is combined to the PCB of the input/output module 200 included in the electronic device 100 according to the present invention. The light emitting device 300A-1 emitting A wavelength band and the light emitting device 300A-2 emitting B wavelength band emit lights to the first light guiding passage 400-1. In the first light guiding passage 400-1, patterns which are brightened in response to the light of B wavelength band are formed in the shape of characters (Menu, Input) or marks (+, -). When lights are emitted from the light emitting device 300A-2, the patterns can emit lights of a specific color in response to the light of B wavelength band.
Although not illustrated in Fig. 15, the first light guiding passage 400-1 can include light penetrating area through which parts of the lights of A and B wavelength bands emitted from the light emitting devices 300A-1, 300A-2 can pass. In this case, the light penetrating area can be formed by the fine patterns included in the first light guiding passage 400-1, in a similar way illustrated in Fig. 3 (d).
Fig. 16 illustrates the first light guiding passage 400-1 shown in Fig. 15. As described with reference to Fig. 15, the first light guiding passage 400-1 delivers information to a user through lighting patterns in response to the light of specific wavelength band emitted from the light emitting devices. On the other hand, the characters and marks shown in Fig. 16 can be implemented by the light penetrating areas which are brightened by the penetrating lights based on the scattered lights by the fine patterns included in the first light guiding passage 400-1.
Fig. 17 is an exploded perspective view showing the input/output module 200 of the electronic device 100 according to another embodiment of the present invention the present invention. In the input/output module 200' illustrated in Fig. 17, sensor pattern 500A is formed on the third light guiding passage 400-3' rather than on the PCB of the second input/output module 230 as is the case with the input/output module 200 illustrated in Fig. 11. Other structures of the input/output module 200' illustrated in Fig. 17 except the location of the sensor pattern 500A is the same as the structure of the input/output module 200 illustrated in Fig. 11, and so detailed explanation of the input/output module 200' is omitted.
Fig. 18 is a detailed view of the third light guiding passage 400-3 illustrated in Fig. 17. Referring to Fig. 18, it can be seen that the sensor pattern 500A formed on the third light guiding passage 400-3 is implemented by transparent electrode. The purpose of this structure is to minimize the effect on the light emitting operation of the input/output module 200.
Fig. 19 illustrates another example of the input/output module 200 included in the electronic device 100 of the present invention. The input/output modules 200 illustrated in Fig. 19 has circular type structure unlike the bar type described earlier.
The input/output module 200 illustrated in Fig. 19 (a) includes circular type light guiding module 400, it can be seen that the first and second light emitting modules 310, 320 emitting red light and green light in the opposite direction are arranged on parts of the light guiding module 400. The red and green lights emitted are guided through the light guiding module 400, and part of the lights are transmitted to the user by passing through the light penetrating area 410 of the light guiding module 400.
The input/output module 200 illustrated in Fig. 19 (b) is arranged on the same surface, and includes the first emitting layer including the first light emitting module 310 and the first light guiding passage 405 guiding the lights emitted from the first light emitting module 310, and the second emitting layer including the second light emitting module 320 and the second light guiding passage 415 guiding the lights emitted from the second light emitting module 320. Also, the first and second light guiding passages 405, 415 include light penetrating area 410, 420 respectively in order to provide the guided and penetrated light to the user, the light being emitted from the corresponding light emitting module of the first and second light emitting modules 310, 320.
Fig. 20 illustrates one example of the light emitting module 300 included in the input/output module 200 included in the electronic device 100 according to the present invention. More specifically, the light emitting module 300 illustrated in Fig. 20 is one example of the light emitting module that can emit lights of various colors by using multiple single-color emitting diodes.
Referring to Fig. 20, the light emitting module 300 includes an emitting diode controller 301, an emitting diode module 302 and a mixing unit 303. The emitting diode controller 301 outputs drive signal for controlling the light emitting operation of the multiple emitting diodes 302A, 302B, 302C included in the emitting diode module 302 in response to the control signal received from the controller 120 of the electronic device 100. In this case, the control signal is generated based on specific information related to the operation of the electronic device 100, which is to be provided to the user through the input/output module 200.
The multiple emitting diodes 302A, 302B, 302C included in the emitting diode module 302 performs the light emitting operation in response to the drive signal of the drive signals which is output from the emitting diode controller 301. In this case, the intensity of the lights emitted from the multiple emitting diodes 302A, 302B, 302C can be different depending on the size of drive signal received.
The mixing unit 303 mixes the lights emitted from the emitting diode module 302, and outputs to the light guiding module 400 of the electronic device 100. In this step, the color and intensity of the lights emitted from the mixing unit 303 can be varied depending on the type and intensity of lights emitted from the emitting diode module 302.
Since the light emitting module 300 of Fig. 20 includes multiple emitting diodes 302A, 302B, 302C that can emit lights of three primary colors, red, green and blue, the types of information (i.e., the types of light color) that can be provided by the light emitting module 300 is greatly varied. In the other implementation of the present invention, however, the light emitting module 300 can include multi-color emitting diode that can emit lights of various colors, in which case the mixing means for mixing lights emitted from multiple emitting diodes may not be needed in the light emitting module 300.
Figs. 21, 22 and 23 illustrate other examples of the input/output module 200 included in the electronic device 100 according to the present invention. The input/output modules 200 illustrated in Figs. 21, 22 and 23 include lighting patterns that are brightened in response to lights of specific wavelength band in the light penetrating area respectively.
Referring Fig. 21 (a), a light emitting module 310 emitting red light and a light guiding module 400 for guiding the light emitted from the light emitting module 310 are included. The light guiding module 400 includes the light guiding passage 405, and a light penetrating area 410 is prepared on parts of the light guiding passage 405. Also, the light penetrating area 410 includes an emitting pattern group 405A, 405B which has the features of emitting, in response to the lights emitted from the light emitting module 310, lights of different wavelength bands than those of the emitted lights.
In this step, the emitting pattern group 405A, 405B can be implemented by pigment layers which are transparent at normal state but, upon receiving the lights emitted from the light emitting module 310, emit lights of different wavelength bands than those of the emitted lights in response to the lights emitted from the light emitting module 310.
The emitting pattern group 405A, 405B is represented by dotted line in Fig. 21 (a), which means that the emitting pattern group 405A, 405B is transparent at normal state, which applies to all emitting patterns represented by dotted line in the specification.
Referring to Fig. 21 (b), when red light is emitted from the light emitting module 310, the emitting pattern groups 405A, 405B emit light of specific color in response to the red light. The emitting pattern group is represented by solid line in Fig. 21 (b), which means that the emitting pattern group 405A, 405B is emitting lights, which applies to all emitting patterns represented by solid line in the specification.
Although the touch sensing module 500 is not shown in the input/output module 200 illustrated in Fig. 21, the input/output module 200 is assumed to be equipped with the touch sensing module 500 in the description of controlling process by user's touch. This will be the same in the examples described below.
For example, if the user touches on the emitting pattern group 405A, 405B at the state of Fig. 21 (b), the controller 120 of the electronic device 100 generates control signal predetermined for the location of the touch, and can change the broadcast channel received by the electronic device 100.
Referring to Fig. 22 (a), it can be seen that the input/output module 200 illustrated in Fig. 22 further includes, compared to the input/output module 200 illustrated in Fig. 21, the light emitting module 320 emitting green light and the light guiding passage 415 guiding the green light. The light penetrating area 420 of the light guiding passage 415 includes emitting pattern group 415A, 415B which emits light of specific wavelength band in response to the green light.
Since the operation of the input/output module 200 related to the emitting patterns in response to red light has been described above, only the operation of the input/output module 200 related to the emitting patterns in response to green light will be described below with reference to Fig. 22.
Referring to Fig. 22 (b), when the light emitting module 320 emits green light, the emitting pattern group 415A, 415B emits light of specific color in response to the green light.
Although the touch sensing module 500 is not shown in the input/output module 200 illustrated in Fig. 22, the control process of the channel by user's touch will be described assuming that the input/output module 200 is equipped with a touch sensing module 500. When the user touches on the emitting pattern group 415A, 415B at the state of Fig. 22 (b), the controller 120 of the electronic device 100 generates control signal predetermined for the location of the touch, and can control the volume of the audio signal which is output from the electronic device 100 through audio output module 140.
It can be seen that the input/output module 200 illustrated in Fig. 23 (a), unlike the input/output modules 200 illustrated in Figs. 21 and 22, has the structure of guiding the lights emitted from the two light emitting modules 310, 320 through the light guiding passage 405 of the light guiding module 400. Also, the light penetrating area 410 of the light guiding passage 405 includes the first emitting pattern group 405A, 405B responding to red light and the second emitting pattern group 415A, 415B responding to green light.
Fig. 23 (b) and (c) illustrate the process of brightening the first emitting pattern group 405A, 405B in response to the red light emitted from the first light emitting module 310, and the process of brightening the second emitting pattern group 415A, 415B in response to the green light emitted from the second light emitting module 320, respectively. These lighting mechanism and control of electronic device 100 through touch are similar to those described with reference to Figs. 21 and 22, and detailed explanation is omitted.

Also the input information received from outside can include external images acquires through a camera (not illustrated).
Referring to Fig. 24 again, the controller 120, upon acquiring the context information, controls at least one of the color and intensities of the light emitted from at least one light emitting module of the multiple light emitting modules included in the light emitting module 300 by reflecting the context information acquired (S110).
Then, the light guiding module 400 guides the lights emitted from multiple light emitting modules including the at least one light emitting module through multiple light guiding passages, and parts of the lights emitted from the multiple light emitting modules are provided to the user by passing through the light penetrating areas included in the multiple light guiding passage (S120). The combination of the lights passing through each of the multiple light penetrating areas constitutes color information corresponding to the context information acquired.

The controller 120 of the electronic device 100 recognizes the operation state of the electronic device 100 (S200). When the operating state of the electronic device 100 is recognized, the controller 120 controls the operation of at least one light emitting module of the multiple light emitting modules included in the light emitting module 300 of the input/output module 200 by reflecting the operating state of the electronic device 100 (S210).
The light guiding module 400, under the control of the controller 120, guides the light emitted from at least one light emitting module, and provides color information corresponding to the operating state of the electronic device 100 to the user through the light penetrating area included in the light guiding module 400 (S220).
Fig. 26 illustrates an example of providing the booting process of the electronic device 100 through the input/output module 200 according to the method of providing information through the input/output module 200 of the electronic device 100 as illustrated in Fig. 25.
Referring to Fig. 26 (a), the user touches the portion of power button 131 of the electronic device 100. Then, the controller 120 starts the booting process of the electronic device 100, and controls the light emitting module 310 to emit light. The light emitted from the light emitting module 310 is guided through the light guiding passage 405 of the light guiding module 400, and part of the guided light is provided to the user through the light penetrating area 410 prepared on the light guiding passage 405.
Referring to Fig. 26 (b) and (c), it can be seen that the controller 120 controls the light emitting module 310 reflecting the booting process so that the intensity of emitted light increases, and accordingly the progress of the booting process of the electronic device 100 is provided to the user through the light penetrating area 410.
Fig. 27 is a flow diagram illustrating another example of providing information through the input/output module 200 of the electronic device 100 as illustrated in Fig. 24. The method of providing information will now be described with reference to the relevant drawings.
First, user's touch on specific location of the touch sensing module 500 is received (S300). Then, the controller 120 of the electronic device 100 selects state information corresponding to the specific location (S310), and controls the operation of emitting light of at least one light emitting module included in the light emitting module 300 by reflecting the selected information (S320).
When light is emitted from the light emitting module of at least one of the light emitting modules, under the control of the controller 120, the input/output module 200의 light guiding module 400 provides the color information corresponding to the selected state information by guiding the light emitted from at least one light emitting module (S330). In this case, the color information corresponding to the selected state information is the part of the guided light shown to the user by passing through the light penetrating area included in the light guiding module 400.
Fig. 28 illustrates an example of providing the information on the state of the electronic device 100 through the input/output module 200 according to the method of providing information through the input/output module 200 of the electronic device 100 as illustrated in Fig. 27.
Referring to Fig. 28, the input/output module 200 includes a light guiding module 400 including the first and second light emitting modules 310, 320, and the first and second light guiding passage 405, 415. The first light emitting module 310 and the first light guiding passage 405 are used to provide operating state of the electronic device 100, and the second light emitting module 320 and the second light guiding passage 415 are used for a user to select the types of information. Although not illustrated in Fig. 28, the input/output module 200 further includes a touch sensing pad for receiving user's touch.
Fig. 28 (a) illustrates the process in which the second light emitting module 320 emits light, and the emitted light is provided to the user in the form of characters corresponding to the state information by penetrating the light penetrating area 420 of the second light guiding passage 415. The user touches the area corresponding to the volume of the audio signal which is output through the audio output module 140 of the light penetrating area 420 included in the second light guiding passage 415 at the state of Fig. 28 (a).
Then, the controller 120 of the electronic device 100 controls the light emitting operation of the first light emitting module 310 so that the light corresponding to the volume of the selected audio signal is provided to the user through the light penetrating area 410 of the first light guiding passage 405, as shown in Fig. 28 (b).
Meanwhile, the controller 120 can control the haptic module 150 so that vibration is generated when the light penetrating area corresponding to the volume of the audio signal is touched. Then, the user can recognize intuitively that color information corresponding to the volume of the audio signal will be provided by the user's touch. In this case, the intensity of vibration, the number of vibrations and the duration of vibration can be varied depending on the location where touch is received. Then, the user can recognize intuitively what type of operating state information he or she has requested.
Fig. 29 illustrates another example in which the state information of the electronic device 100 is provided through the input/output module 200 according to the method of providing information through the input/output module 200 of the electronic device 100 illustrated in Fig. 27. The electronic device 100 is assumed to be a printer.
Referring to Fig. 29, the input/output module 200 includes the first through fourth light emitting modules 310, 320', 330', 340', and the first through fourth light guiding passages 405, 420, 430, 440 corresponding to the first through fourth light emitting modules 310, 320', 330', 340' respectively.
The first light emitting module 310 emits white light, and the first light guiding passage 405 guides the white light emitted from the first light emitting module 310, and parts of guided lights are provided to the user by penetrating the light penetrating area 410 prepared in the shape of characters 'COLOR' corresponding to the amount of the ink stored in the printer.
The second through fourth light emitting modules 320', 330', 340' include multi-color light emitting device which can emit light of color determined by the driving signal respectively. The light penetrating area is the whole region shown to the user in each of the second through fourth light guiding passage 420, 430, 440. Although not shown in Fig. 29, the input/output module 200 further includes the touch sensing pad for receiving user's touch.
The user touches the light penetrating area 410 included in the first light guiding passage 405 at the state of Fig. 29 (a). Then, the controller 120 of the electronic device 100 controls, as illustrated in Fig. 29 (b), the second light emitting module 320' so that the light of the color of the first ink (COLOR 1) installed on the electronic device 100 is emitted, controls the third light emitting module 330' so that the light of the color of the second ink (COLOR 2) installed on the electronic device 100 is emitted, and controls the fourth light emitting module 340' so that the light of the color of the third ink (COLOR 3) installed on the electronic device 100 is emitted. At this step, the amount of the lights emitted from the second through fourth light emitting module 320', 330', 340' is determined by the amount of corresponding ink.
The lights emitted from each of the second through fourth light emitting modules 310, 320', 330', 340' are guided through the second through fourth light guiding passages, and the guiding distance of the lights emitted from the second through fourth light emitting modules 310, 320', 330', 340' can be different depending on the amount of corresponding ink.
Fig. 30 is a flow diagram illustrating another example of the method of providing information through the input/output module 200 of the electronic device 100 shown in Fig. 24. The method of providing information will now be described with reference to relevant drawings.
Touch on the specific location of the touch sensing pad 510 of the touch sensing module 500 is received (S400). The controller 120 of the electronic device 100, upon receiving the touch, changes the operating state of the electronic device 100 in response to the touch received (S410). Then, the controller 120 controls the light emitting operation of at least one light emitting module of the multiple light emitting modules included in the light emitting module 300 by reflecting the information on the changed operating state of the electronic device 100 (S420).
Then, the light guiding module 400 of the input/output module 200 guides the lights emitted from at least one light emitting module so that the color information corresponding to the information on the changed operating state is provided to the user (S430). As described above, the color information corresponding to the information on the changed operating state means the part of the guided light which is provided to the user by penetrating the light penetrating area included in the light guiding module 400.
Fig. 31 illustrates one example in which the operating state of the electronic device 100 according to the present invention is changed and the changed operating state is provided through the input/output module 200 according to the method of providing information illustrated in Fig. 30. More specifically, Fig. 31 illustrates the process in which the volume of the audio signal which is output through the audio output module 140 of the electronic device 100 is changed in response to user's touch, and the result of changed volume of the audio signal is provided through the input/output module 200.
Referring to Fig.31 (a), it can be seen that the input/output module 200 includes the first and second light emitting modules 310, 320 reflecting the volume of the audio signal, and the light guiding module 400 which guides the lights emitted from the light emitting modules 310, 320 in the opposite direction. In the light guiding passage 405 of the light guiding module 400, a light penetrating area which is arranged with constant interval is prepared.
In Fig. 31 (a), the location of the light penetrating area through which the mixed light of the red light emitted from the first light emitting module 310 and green light emitted from the second light emitting module 320 penetrates corresponds to the volume value of the audio signal. At the state of Fig. 31 (a), the user touches right region of the light penetrating area through which the mixed light passes. Then, the controller 120 of the electronic device 100 controls, as shown in Fig. 31 (b), the light emitting operation of the first and second light emitting modules 310, 320 so that the location of the light penetrating area through which the mixed light passes moves to the right.
At the state of fig. 31 (b), the user touches left region of the light penetrating area through which the mixed light passes. Then, the controller 120 controls, as shown in Fig. 31 (c), the light emitting operation of the first and second light emitting modules 310, 320 so that the location of the light penetrating area through which the mixed light passes moves to the left.
Meanwhile, as illustrated in Fig. 31 (b), the controller 120, upon receiving user's touch through the touch sensing module 500, can control the haptic module 150 to generate vibration. Then, the user can recognize intuitively that the volume of the audio signal will be changed by his or her touch.
Fig. 32 is a flow diagram illustrating another example of the method of providing information through the input/output module 200 of the electronic device 100 illustrated in Fig. 24. The method of providing information will now be described with reference to relevant drawings.
User's touch is received through the touch sensing module 500 of the input/output module 200 (S500). Then, the user changes at least one of the operating state of the electronic device 100 and set-up information of the electronic device 100 based on at least one of the direction and distance of the movement of touch (S510).
Then, the controller 120 controls the light emitting operation of at least one light emitting module of the light emitting module 300 by reflecting at least one of the information related to changed operating state and the set-up information (S520). Then, the light guiding module 400 of the input/output module 200 guides the light emitted from at least one of the light emitting modules, and provides color information corresponding to at least one of the information related to changed operating state and the set-up information to the user (S530).
Fig. 33 illustrates one example in which the operating state of the electronic device 100 according to the present invention is changed and the changed operating state is provided through the input/output module 200 according to the method of providing information illustrated in Fig. 32. More specifically, Fig 33 illustrates the process in which the volume of the audio signal which is output from the audio output module 140 of the electronic device 100 is changed in response to user's touch, and the result of volume change of the audio signal is provided through the input/output module 200.
Referring to Fig. 33 (a), it can be seen that the input/output module 200 includes a light emitting module 310 emitting the light reflecting the volume of the audio signal, and a light guiding module 400 guiding the light emitted from the light emitting module 310. Light penetrating areas 410 are prepared on the light guiding passage 405 of the light guiding module 400 with constant intervals.
The guiding distance of the red light emitted from the light emitting module 310 in Fig. 33 (a) corresponds to the value of current volume of audio signal. At the state of Fig. 33 (a), the user moves the touch to the right. Then, the controller 120 of the electronic device 100 controls, as illustrated in Fig. 33 (b), the light emitting operation of the light emitting module 310 so that the guiding distance of the red light is increased by reflecting the moving distance of the touch.
Meanwhile, the haptic module 150 of the electronic device 100 can generate vibration according to the movement of the user's touch. The controller 120 of the electronic device 100 can control the haptic module 150 so that more strong vibration is generated as the moving distance of the touch increases. Then, the user can recognize through tactile sense that the audio signal which is output from the electronic device 100 increases by the user's touch.
At the state of Fig. 33 (b), the user moves the touch to the left. Then, the controller 120 can control, as illustrated in Fig. 33 (c), the electric signal provided to the light emitting module 310 so that the penetrating distance of the red light is decreased.
Meanwhile, the haptic module 150 of the electronic device 100 can control the haptic module 150 so that weaker vibration is generated as the user moves the touch. Then, the user can recognize through tactile sense that the volume of the audio signal which is output from the electronic device 100 is decreased by the touch of the user. It is shown in Fig. 33 that vibration intensity of the haptic module 150 can be controlled by the movement of the touch of the user. The controller 120, however, can also control the intensity of the vibration generated by the haptic module 150 by the location of the touch received through the touch sensing module 500.
Fig. 34 illustrates one example in which the operating state of the electronic device 100 according to the present invention is changed and the changed operating state is provided through the input/output module 200 according to the method of providing information illustrated in Fig. 32. More specifically, Fig. 34 illustrates that the printing mode of the electronic device 100, which is implemented through a printer, can be set or changed between color mode and black and white mode in response to the movement of user's touch.
Referring to Fig. 34 (a), it can be seen that the input/output module 200 includes the first and second light emitting modules 310, 320 and the light guiding module 400, and part of the light guiding module 400 includes the light penetrating area 410, and the light guiding module 400 guide the lights emitted from the first and second light emitting modules 310, 320 in the opposite direction.
At the state of Fig. 34 (a), the user moves the touch to the right while keeping the touch on the input/output module 200. Then, the controller 120 of the printer 100 sets the printing mode of the printer 100 to black and white mode. Then, the controller 120 controls, as illustrated in Fig. 34 (b), the light emitting operation of the first and second light emitting modules 310, 320 so that the mixing area of the lights emitted from the first and second light emitting modules 310, 320 moves to the right of the region where the pattern representing black and white mode is displayed.
The user moves the touch on the input/output module 200 from right to left at the state of Fig. 34 (b). Then, the controller 120 changes the printing mode from black and white mod to color mode. Then, the controller 120 controls, as illustrate in Fig. 34 (c), the light emitting operation of the first and second light emitting modules 310, 320 so that the mixing area of the lights emitted from the first and second light emitting modules 310, 320 moves to the left of the area where the pattern representing color mode is displayed.
Meanwhile, the haptic module 150 of the electronic device 100 can generate vibration according to the movement of user's touch. Then, the user can recognize through tactile sense that the printing mode of the printer 100 is changed by the user's touch. The controller 120 can also set the number and duration of vibrations of the haptic module 150 differently depending on the printing mode so that the user can recognize the printing mode intuitively through tactile sense. For example, the controller 120 can control the haptic module 150 to generate the first vibration when the printer 100 is in black and white mode, and generate the second vibration when the printer 100 is in color mode.
Fig. 35 is a flow diagram illustrating another example of providing information through the input/output module 200 of the electronic device 100 illustrated in Fig. 24. The method of providing information will be described with reference to relevant drawings.
The controller 120 of the electronic device 100 acquires context information including at least one of the information related to the current operating state of the electronic device 100 and the information received from outside. (S600). Then, the controller 120 controls the color and intensity of the color emitted from the multi-color light emitting device included in the input/output module 200 according to the acquired context information (S610). Here, the color of the light emitted from the multi-color light emitting device can be varied depending on the types of the acquired context information, and the amount of the light emitted from the multi-color light emitting device can also be varied depending on the amounts represented by the acquired context information.
When light is emitted from the multi-color light emitting device, the light guiding module 400 of the input/output module 200 guides the light emitted from the multi-color light emitting device through the light guiding passage and provides color information corresponding to the acquired context information, and the pattern included in the light penetrating area of the light guiding passage emits light in response to the light emitted from the multi-color light emitting device (S620). In this case, the emitting pattern can be characters, marks, shapes or combination thereof representing the acquired context information.
Fig. 36 illustrates an example in which the information related to the operating state of the electronic device 100 according to the present invention is provided, according to the method of providing information illustrated in Fig. 35, to a user through the color, amount of the light emitted from the light emitting module 310' and the light emitted from the emitting pattern.
Referring to Fig. 36 (a), the input/output module 200 includes a light emitting module 310' and a light guiding module 400. The light emitting module 310' can emit different colors of lights depending on the type of the information provided through the input/output module 200. The emitting pattern which is represented by dotted line in the light penetrating area 410 of the light guiding passage 405 of the light guiding module 400 emits light in response to specific wavelength band of lights emitted from the light emitting module 310'.
At the state of Fig. 36 (a), the light emitting module 310' emits red light which is allocated to the volume of the audio signal which is output from the electronic device 100. The red light emitted from the light emitting module 310' is guided through the light guiding passage 405. Then, as illustrated in Fig. 36 (b), the emitting pattern 'VOL' in the shape of characters corresponding to the audio signal among the emitting patterns displayed on the light guiding passage 405 emits light in response to the red light. At this step, the color of light emitted from the emitting pattern is preferably the color different from the red so that the user can easily recognize the emitting pattern which emits lights. Also, the guiding distance of the green light in the light penetrating area 410 corresponds to the volume of the audio signal.
At the state of Fig. 36 (a), the light emitting module 310' emits green light which is allocated to the brightness of the images which is output from the electronic device 100. The green light emitted from the light emitting module 310' is guided through the light guiding passage 405. Then, as illustrated in Fig. 36 (c), the emitting pattern 'BRI' in the shape of characters corresponding to the brightness of the images among the emitting patterns displayed on the light guiding passage 405 emits light in response to the green light. At this step, the color of light emitted from the emitting pattern is preferably the color different from the green so that the user can easily recognize the emitting pattern which emits lights. Also, the guiding distance of the green light in the light penetrating area 410 corresponds to the brightness of the images.
Fig. 37 is a flow diagram illustrating another example to provide information through the input/output module 200 of the electronic device 100 illustrated in Fig. 24. The method of provide information will now be described with reference to relevant drawings.
The controller 120 of the electronic device 100 acquires context information including at least one of the information related to the current operating state of the electronic device 100 and the information received from outside. (S700). Then, the controller 120 selects a light emitting module which emits light to the specific light guiding passage of the light guiding module 400 based on the acquired context information (S710). At this step, the light emitting module which emits light to the specific light guiding passage can vary depending on the type of the acquired context information, and the amount of the light emitted from the light emitting module can vary depending on the amount represented by the acquired context information.
When light is emitted from the selected light emitting module, the specific light guiding passage guides the light emitted from the selected light emitting module and provides color information corresponding to the acquired context information to the user, and the pattern included in the light penetrating area of the light guiding passage emits light in response to the light emitted from the selected light emitting module (S720). In this case, the emitting pattern can be characters, marks, shapes or combination thereof representing the acquired context information.
Fig. 38 illustrates an example in which, according to the method of providing information of the present invention as illustrated in Fig. 37, the information related to operating state of the electronic device 100 according to the present invention is provided to the user through the color and amount of the light emitted from the light emitting modules 310, 320 and the light emitted from the emitting patterns.
Referring to Fig. 38 (a), the input/output module 200 includes the light emitting modules 310, 320 and the light guiding module 400. Each of the light emitting modules 310, 320 can emit red or green lights depending on the type of information provided through the input/output module 200. The emitting pattern, which is represented by dotted line in the light penetrating area 410 of the light guiding passage 405 of the light guiding module 400, emits light in response to the light of specific wavelength band emitted from the light emitting modules 310, 320.
At the state of Fig. 38 (a), red light is emitted from the light emitting device 310 allocated to the volume of the audio signal which is output from the electronic device 100. The red light emitted from the light emitting module 310 is guided through the light guiding passage 405. Then, as illustrated in Fig. 38 (b), the emitting pattern 'VOL' which is a character pattern corresponding to the audio signal of the emitting patterns displayed on the light guiding passage 410 emits light in response to the red light. At this step, the color of light emitted from the emitting pattern is preferably the color different from the red so that the user can easily recognize the emitting pattern which emits lights. Also, the guiding distance of the green light in the light penetrating area 410 corresponds to the volume of the audio signal.
At the state of Fig. 38 (a), the light emitting module 320 allocated to the brightness of the image signal which is output from the electronic device 100 emits green light. The green light emitted from the light emitting module 320 is guided through the light guiding passage 405.
Then, as illustrated in Fig. 38 (c), the emitting pattern 'BRI' in the shape of characters corresponding to the brightness of the emitting pattern displayed on the light penetrating area 410 of the light guiding passage 405 emits light in response to the green light. At this step, the color of light emitted from the emitting pattern is preferably the color different from the green so that the user can easily recognize the emitting pattern which emits lights. Also, the guiding distance of the green light in the light penetrating area 410 corresponds to the brightness of the image.
Fig. 39 illustrates another example in which, according to the method of providing information of the present invention as illustrated in Fig. 37, the information related to operating state of the electronic device 100 according to the present invention is provided to the user through the color and amount of the light emitted from the light emitting modules 310, 320, 330, 340 and the light emitted from the emitting patterns.
The mixing area of the lights emitted from the first and second light emitting modules 310, 320 represents relative location of the value represented by the information provided to the user. The mixing area of lights emitted from the third and fourth light emitting modules 330, 340 is used to induce lighting of the emitting pattern designated in the light penetrating area 420 of the light guiding passage 415. In other words, the emitting pattern can emit lights in response to the lights of certain wavelength band generated in the mixing area.
For example, the user identifies the light emitted in the shape of characters from the emitting pattern, and can see that the information provided through the mixing area of the lights emitted from the first and second light emitting modules 310, 320 in Fig. 39 (a) is the volume of the audio signal, and that the information provided through the mixing area of the lights emitted from the first and second light emitting modules 310, 320 in Fig. 39 (b) is the brightness of the image signal.
Fig. 40 is a flow diagram illustrating yet another example of providing information through the input/output module 200 of the electronic device 100 according to the present invention. The method of providing information will now be described with reference to relevant drawings.
Multiple operating states and multiple emitting patterns corresponding respectively to the multiple operating states are stored in the storing unit 170 of the electronic device 100 (S800). The electronic device 100 enters a specific operating mode of the multiple operating modes (S810). At this step, the operating modes of the electronic device 100 can include booting mode, wait mode, wait power save mode, cleaning mode, data receiving and transmitting mode, set up mode and mode for connection with external devices.
Then, the controller 120 of the electronic device 100 controls the light emitting operation of at least one light emitting module of the multiple light emitting modules included in the input/output module 200 according to the emitting pattern corresponding to the specific operating mode (S820). In this case, control of the light emitting operation of the light emitting module means controlling at least one of the color and intensity of the light emitted from the light emitting module.
The light guiding module 400 of the input/output module 200 can provide color information representing the specific operating mode to the user by guiding the light emitted from at least one of the light emitting modules (S830). More specifically, the color information provided to the user means the color information provided to the user by the part of the guided light which penetrates the light penetrating area included in the light guiding module 400.
Fig. 40 is a flow diagram illustrating another example of providing information through the input/output module 200 of the electronic device 100 according to the present invention. The method of providing information will now be described with reference to relevant drawings.
Multiple operating states, at least one input pattern corresponding respectively to the multiple operating states and at least one emitting pattern corresponding respectively to the at least one input pattern are stored in the storing unit 170 of the electronic device 100 (S900). Here, the at least one input pattern can be a touch pattern which is input through the touch on the touch sensing module 500 of the input/output module 200. However, the scope of the present invention is not limited to these patterns. For example, the at least one input pattern can be received through a touch sensing module or input button which is separated from the input/output module 200.
In the state where the electronic device 100 has entered the specific operation mode of the multiple operation modes (S910), at least one input pattern corresponding to the specific operation mode is received through input means (S920).
Then, the controller 120 of the electronic device 100 controls light emitting operation of at least one light emitting module of the multiple light emitting modules included in the input/output module 200 based on the emitting pattern corresponding to the received input pattern (S930).
The light guiding module 400 of the input/output module 200 can provide color information related to the specific operating mode by guiding the light emitted from at least one of the light emitting modules (S940).
Fig. 42 illustrates yet another example of the input/output module 200 included in the electronic device 100 according to the present invention. Referring to Fig. 42, the input/output module 200 includes a first input/output module 220 and a second input/output module 230.
Each of the first and second input/ output modules 220, 230 represents context information of the electronic device through the light provided based on the emission and composition of lights, and can operate as a means for touch. The first and second input/ output modules 220, 230 can be mounted on PCB. As shown in Fig. 42, one end of the second input/output module 230 is combined with one end of the first input/output module 220. As shown in Fig. 42, the input/output module 200 can be arranged on one edge portion of the bezel of the electronic device 100 if the first and second input/ output modules 220, 230 are connected in the L shape.
The first input/output module 220 includes a touch sensing module (not illustrated), a first light guiding module 400-1 and first and second light emitting modules 300A, 300B. The entire touch sensing module is not illustrated in Fig. 42, and only the sensor pattern 500A included in the touch sensing module for detecting user's direct or indirect touch is illustrated.
The first light guiding module 400-1 guides incident lights and can include light penetrating area (not illustrated) on at least part of the module. The light penetrating area included in the light guiding module has been described above and explanation is omitted. One end of the first light guiding module 400-1 of the first input/output module 220 can be combined with one end of the second light guiding module 400-2 of the second input/output module 230.
The first and second light emitting modules 300A, 300B are combined with one corresponding end of the both ends of the first light guiding module 400-1, and emit specific color of light to the first light guiding module 400-1. The colors of the lights emitted from the first and second light emitting modules 300A, 300B can be different each other, and the different colors of lights emitted can be mixed at the first light guiding module 400-1.
Part of the different colors of lights emitted and mixed lights can be provided to the user through the light penetrating area. As described above, the light provided to the user through the light penetrating area can be color information corresponding to the context information including operating state of the electronic device 100.
The second input/output module 230 also includes, as in the case of the first input/output module 220, a sensor pattern 500A, the second light guiding module 400-2, and the first and second light emitting modules 300A, 300B. Those who have common knowledge in the field to which the present invention belongs (referred to as 'those skilled in the art') will be able to derive the operational characteristics of the second input/output module 230 easily from the operation of the constructing elements of the first input/output module 220. Therefore, detailed explanation on the second input/output module 230 is omitted.
The controller 120 of the electronic device 100 can control at least one of the intensity and color of the lights emitted from at least one of the first and second input/ output modules 220, 230 by reflecting the context information acquired based on the touch on one of the first and second input/ output modules 220, 230. In other words, the first and second input/ output modules 220, 230 can be used as means for input and output of information.
For example, when touch is received through at least one of the touch sensing module of the first and second input/ output modules 220, 230, the controller 120 can perform a specific function of the electronic device 100 based on at least one of location and movement of the touch. In this case, the controller 120 can control at least one of the color and intensity of the lights emitted from at least one of the first and second input/ output modules 220, 230 by reflecting the state of performance of the a specific function.
Specific examples of the specific functions performed by the electronic device 100 in response to the touch received through the first and second input/ output modules 220, 230 will be described below.
The controller 120 can enlarge or reduce the image displayed on the display device 110 based on at least one of the location and movement of the touch received through the first and second input/ output modules 220, 230. In this case, the controller 120 can change the color information which is output through the first and second input/ output modules 220, 230 according to whether the image has been enlarged or reduced. Then, enlarging or reducing of the image can be intuitively recognized by visually identifying the changed color information. These features of intuitive providing of information can be similarly applied in performing specific functions which will be described later.
The controller 120 can also change the screen displayed on the display device 110 to another screen based on at least one of the location and movement of the touch received through the first and second input/ output modules 220, 230. For example, in the applications executed in the electronic device 100 such as e-book application in which multiple pages of different screens are displayed on the display device 110, pages can be navigated to the previous, next or specific page based on the location or movement of the touch received through the first and second input/ output modules 220, 230.
The controller 120 can also scroll the screen displayed on the display device 110 to a specific direction based on at least one of the location and movement of the touch received through the first and second input/ output modules 220, 230.
The controller 120 can also change the operating state of the electronic device 100 based on at least one of the location and movement of the touch received through the first and second input/ output modules 220, 230. In this case, the changed operating state can be reflected to the color information through the first and second input/ output modules 220, 230.
Examples of using the first and second input/ output modules 220, 230 as a means for information output as well as a means for information input have been described above. On the other hand, the first and second input/ output modules 220, 230 can also be used as a means for merely outputting information.
For example, the controller 120 of the electronic device 100 can control one of the color and intensity of the lights emitted from at least one of the first and second input/ output modules 220, 230 by reflecting the operating state of the electronic device 100. In other words, the first and second input/ output modules 220, 230 can be used as a means for merely outputting information.
The first and second input/ output modules 220, 230 can be used as an input means related to specific functions of applications executed in the electronic device 100. More specifically, when the specific application is executed, the controller 120 can set the first input/output module 220 to an input means for executing a first function of the specific application, and set the second input/output module 230 to an input means for executing a second function of the specific application.
For example, when the application executed in the electronic device 100 is a video playing application, the controller 120 can set the first input/output module 220 to a means for controlling sound of the video playing application by using touch, and set the second input/output module 230 to a means for controlling brightness of the video by using touch.
Also, the first and second input/ output modules 220, 230 can be used as an information output means for outputting information reflecting the operating state of specific functions of the specific application. More specifically, the first input/output module 220 can be set to an information output means for outputting the color information reflecting the operating state of a first function related to the specific application, and set the second input/output module 230 to an information output means for outputting the color information reflecting the operating state of a second function related to the specific application.
For example, when the application executed in the electronic device 100 is a video playing application, the controller 120 can set the first input/output module 220 to a means for outputting color information reflecting the result of controlling sound of the video playing application, and set the second input/output module 230 to a means for outputting color information reflecting the result of controlling brightness of the video.
Fig. 43 illustrates the process of guiding lights performed in the input/output module 200 illustrated in Fig. 42. The first light emitting module 300A emits lights directly to the guiding direction of the first light guiding module 400-1 in the first input/output module 220 of the input/output module 200. The second light emitting module 300B of the first input/output module 220, however, emits lights toward the contacting surface 400-P of the first light guiding module 400-1 and the second light guiding module 400-2 of the second input/output module 230. Then, the lights emitted from the second light emitting module 300B are totally reflected on the contacting surface 400-P, and transmitted to the first light guiding module 400-1 for guiding.
The second light emitting module 300D included in the second input/output module 230 also emits lights indirectly toward the contacting surface 400, and the lights emitted from the second light emitting module 300D are totally reflected on the contacting surface 400-P, and transmitted to the second light guiding module 400-2 for guiding.
Fig. 44 conceptually illustrates the operation of mixing lights performed at the input/output module 200 illustrated in Fig. 42.
Fig. 44 (a) illustrates emitting, guiding and mixing of lights only at the first input/output module 220 of the input/output module 200, and Fig. 44 (b) illustrates emitting, guiding and mixing of lights only at the second input/output module 230 of the input/output module 200. Fig. 44 (c) illustrates emitting, guiding and mixing of lights both at the first and second input/ output modules 220, 230.
Fig. 45 is a flow diagram illustrating the method of performing a specific function in the electronic device 100 according to the present invention based on the touch on the input/output module 200 illustrated in Fig. 42. The method of performing a specific function will be described below with reference to relevant drawings.
First, touch is received through at least one of the touch sensing module 500 in the first and second input/ output modules 220, 230 included in the input/output module 200 (S1000). Then, the controller 120 of the electronic device 100 controls one of the color and intensity of the lights emitted from at least one of the first and second input/ output module 220, 230 based on at least one of the location and movement of the received touch (S1010).
Then, the first and second light guiding modules 220, 230 of the first and second input/ output modules 220, 230 perform guiding of the emitted lights and the specific function (S1020). At this step, the light provided to the user through the guided light can be color information corresponding to the specific function.
Fig. 46 illustrates that the method of performing specific function as illustrated in Fig 45 is performed by the electronic device 100 according to the present invention which is implemented by smart pad. Fig. 46 represents that execution of an e-book application is shown on the display device 110 of the smart pad 100.
Referring to Fig. 46, it can be seen that the input/output module 200 is arranged on one edge portion of the bezel of the smart pad 100. More specifically, the first input/output module 220 of the input/output module 200 is arranged in the traversal direction on the edge portion, and the second input/output module 230 of the input/output module 200 is arranged in the longitudinal direction on the edge portion.
As illustrated in Fig. 46, the user can change the page showing the execution of the e-book application based on the touch on the second input/output module 230. Also, the user can zoom in or zoom out the screen showing the execution of the e-book application based on the touch on the first input/output module 220.
Fig. 47 illustrates another example of the input/output module 200 included in the electronic device 100 according to the present invention. Fig. 48 is an exploded perspective view of the input/output module 200 illustrated in Fig. 47. Referring to Figs. 47 and 48, the input/output module 200 includes the first input/output module 220, the second input/output module 230 and the third input/output module 240.
Detailed explanation is omitted since those skilled in the art will be able to derive the operational characteristics of the first and second input/ output modules 220, 230 from the explanation described with reference to Figs. 42- 46.
The third input/output module 240 is arranged between the end portions of the first and second input/ output modules 220, 230. Depending on the types of implementation of the present invention, the third input/output module 240 can be combined to the one end portion of the first input/output module 220 or to the one end portion of the second input/output module 230.
The third input/output module 240 can also operate as a means for input information by touch, or as a means for outputting information providing images corresponding to specific functions that can be executed by the electronic device 100.
In other words, when touch is received through the third input/output module 240, the controller 120 of the electronic device 100 can perform the specific functions based on the received touch. The color information related to the operating state of the specific functions can be provided through at least one of the first and second input/ output modules 220, 230.
The light emitting modules 300A, 300D included in the first and second input/ output modules 220, 230 is an edge type light emitting module which emits lights at each of the both ends of the corresponding light guiding module of the light guiding modules 400-1, 400-2 to the to the corresponding light guiding module, but the light emitting module 300E included in the third input/output module 240 can be a direct type light emitting module. It is obvious that the light emitting module 300E can also be implemented as an edge type module.
Fig. 49 illustrates one example of the third input/output module 240 of the input/output module 200 illustrated in Fig. 47. When the LED 300E included in the third input/output module 240 emits light, the emitted light is guided through the light guiding module 400-3, and provided to the user by penetrating the light penetrating area 410-3 formed on the upper part of the third light guiding module 400-3. The light penetrating area 410-3 includes an opaque pattern, so the user can recognize the pattern through the light passing through the area other than the area of the light penetrating area 410-3.
Although the touch sensing module included in the third input/output module 240 is not illustrated in Fig. 49, the portion where the pattern is marked can operate as a home return key operating in response to user's touch received by the touch sensing module.
Fig. 50 illustrates another example of the third input/output module 240 of the input/output module 200 illustrated in Fig. 47. First, the direct type module 240 illustrated in the Fig. 50 (a) will be described.
The light with specific wavelength band emitted from the LED 300E' of direct type as illustrated in Fig. 49 is emitted through the light guiding module 400-3. Then, it can be seen that part of the emitted light of specific wavelength band is emitted through the light penetrating area 410-3. At this time, the pattern included in the light penetrating area 410-3 emits light of specific color in response to the emitted light of specific wavelength band. The pattern can be in the shape of an image corresponding to a specific function that can be performed in the electronic device 100. As explained with reference to Fig. 49, the area marked by the pattern can be used as a home return button operating in response to user's touch.
The LED 300E' can also emit light of a wavelength band other than the specific wavelength band. In this case, other patterns which emit lights of colors other than the specific color in response to the lights of other wavelength band can be included in the light penetrating area 410-3.
Also, according to another embodiment of the present invention, the patterns which emit lights of colors other than the specific color in response to the lights of other wavelength band can be included in other layer than the layer including the pattern. As described above, the third input/output module 240 can provide images corresponding to multiple functions performed in the electronic device 100.
Then, the edge type module 240 illustrated in Fig. 50 (b) will be described. The third input/output module 240 also includes edge type LED 300E" as in the case of the first and second input/ output modules 220, 230. The LED 300" emits light of a specific wavelength band. Then the emitted light is guided through the light guiding module 400-3, and part of the light passes through the light penetrating area 410-3A. At this step, the pattern 400-3" included in the light penetrating area 410-3A can emit light of specific color in response to the emitted light.
As in the case above described with reference to Fig. 50 (a), the light emitted from the LED 300E" can emit light of other wavelength band, and other patterns can be included in the light penetrating area 410-3A, so the third input/output module 240 can provide images corresponding to multiple functions.
Also, the third input/output module 240 can also have multi-layer structure as illustrated in Fig. 50 (b), in which the structures are arranged vertically. In this case, the light emitting module included in each layer can emit lights of different wavelength band, and the emitting pattern included in each of the layer can also have different shapes. In other words, the third input/output module 240 can provide images corresponding to multiple functions based on the multi-layer structure.
Fig. 51 illustrates an example in which the method of performing a specific function as illustrated in Fig. 47 is applied to the electronic device 100 according to the present invention implemented by a smart pad. More specifically, the first input/output module 220 of the input/output module 200 is arranged in traversal direction of the edge portion, the second input/output module 230 is arranged in longitudinal direction of the edge portion, and the third input/output module 240 is arranged between the first and second input/ output modules 220, 230.
In Fig. 51, the user can perform specific functions of the e-book application executed on the smart pad through touch on the first and second input/ output modules 220, 230, and also can perform home return function through touch on the pattern marked on the third input/output module 240.
Fig. 52 illustrates examples in which multiple input/output modules are arranged in the input/output module 200 included in the electronic device 100 according to the present invention. The numerals in Fig. 52 represent the first through third input/ output modules 220, 230, 240 illustrated above.
Referring to Fig. 52, it can be seen that the third input/output module 240 in not arranged between the first and second input/ output module 220, 230 like the third input/output module 240 illustrated in Figs. 47 and 48, but can be arranged on at least one end of each of the first and second input/ output module 220, 230 in various shapes. The arrangement of the input/output modules illustrated in Fig. 52 is just one of implementations of the present invention, and not intended to limit the scope of the present invention.
It has been described in the above with reference to Figs. 42-52 that each one end of the bar-type input/output module pair can be combined in L shape. However, the present invention is not limited to this shape. For example, the input/output module pair each end of which is combined can form a curve rather than a line, the combining shape of the input/output module pair can be shapes other than L shape. Also, the number of input/output modules whose ends are combined is not limited to 2.
Fig. 53 illustrates another example of the input/output module 200 included in the electronic device 100 according to the present invention. The input/output module 200 can be used to represent context information of the electronic device 100 based on the emission and composition of lights or as an input means through touch. Referring to Fig. 53, the input/output module 200 includes a first input/output module 220 and a second input/output module 230.
Those skilled in the art would be able to induce the structure and features of the first input/output module 220 and the second input/output module 230 from the explanation described with reference to Figs. 42-52. So, explanation on this is omitted.
The input/output module 200 illustrated in Fig. 53 differs from that of the embodiments described above in that part of the area in the first input/output module 220 for guiding the light representing the context information crosses part of the area in the second input/output module 230 for guiding the light representing the context information.
The light penetrating area of the light guiding module of each of the first and second input/ output modules 220, 230 may not be formed within certain range from the crossing area since unwanted mixing of lights guided by the first input/output module 220 and the lights guided by the second input/output module 230 can take place.
Fig. 54 is an enlarged view of parts of the input/output module 200 illustrated in Fig. 53. Referring to the figure in which one end of the first input/output module 220 of the input/output module 200 is enlarged, it can be seen that light guiding structure is formed on the first light guiding module 400-1 of the first input/output module 220 in order to guide lights emitted from the light emitting module 300A to the direction of the first input/output module 220. The light guiding structure is prepared for guiding the lights emitted from the light emitting module 300A in the straight direction, and can be implemented by material having excellent light guiding capacity compared to other parts of the first light guiding module 400-1.
Also, the light guiding structure plays the role of attenuating the light guided to the second light guiding module 400-2 of the second input/output module 230 among the lights guided by the first light guiding module 400-1 of the first input/output module 220. Also, the light guiding structure plays the role of attenuating the light guided to the second input/output module 230 among the lights guided by the second input/output module 230.
Referring to Fig. 54 in which the crossing area of the first and second input/ output modules 220, 230 is enlarged, it can be seen that most of the lights guided through the light guiding structure of the second input/output module 230 is guided through the second input/output module 230 and only part of the guided lights are guided to the first input/output module 220.
Although the light guiding structure illustrated in Fig. 54 has a cross section of semicircle, the scope of the present invention is not limited to the above structure. For example, the cross section of the light guiding structure formed on the input/output module 200 of the electronic device 100 according to the present invention can be circle or quadrangle.
Fig. 55 is an exploded perspective view of another example of the input/output module 200 included in the electronic device 100 according to the present invention. It can be seen that the input/output module 200 includes multiple edge type light emitting modules 300A-300D arranged at the end of the cross-shaped PCB and direct type light emitting module 300E arranged at the crossing area of the cross-shaped PCB.
As described above, the first and second light emitting modules 300A, 300B of the light emitting modules 300A, 300D can be combined with a light guiding plate to form a first input/output module 200, and the third and fourth light emitting modules 300C, 300D can be combined with a light guiding plate to form a second input/output module 230.
The direct type light emitting module 300E can form third input/output module 240 as described before with reference to Fig. 49 or 50. In this case, the shape in the shape of a leaf marked on the light guiding plate can be an opaque pattern or an emitting pattern illustrated in Figs 49 and 50.
Fig. 56 illustrates another example of the input/output module 200 included in the electronic device 100 according to the present invention. Referring to Fig. 56, it can be seen that the first input/output module 220 and the second input/output module 230 of the input/output module 200 can be arranged on other planes which are vertically separated. Other than these features, light emitting modules are arranged at both ends of the each first and second input/ output modules 220, 230, as illustrated in Figs. 53 and 54, thereby guiding the light emitted from the light emitting module and providing part of the guided light to the user through the light penetrating area. Detailed structure of the input/output module is not illustrated in Figs. 56-57, since these figures are intended to illustrate the arrangement between input/output modules.
In this case, the first and second input/ output modules 220, 230 may not include the light guiding structure described with reference to Figs. 53 and 54 since there is little chance of guiding lights between the modules due to the arrangement of the light guiding module of the first and second input/ output modules 220, 230 on separate planes.
Fig. 57 illustrates yet another example of the input/output module 200 included in the electronic device 100 according to the present invention. Referring to Fig. 57, it can be seen that the first input/output module 220, the second input/output module 230 and the third input/output module 240 of the input/output module 200 can be arranged on other planes separated vertically.
The structure and operational characteristics of the first and second input/ output modules 220, 230 can be identical with or similar to those described with reference to Fig. 56. The third input/output module 240 can have light emitting structure of direct type or edge type as illustrated in Figs. 49 and 50.
As described above, the third input/output module 240 can operate as a means of inputting information for selecting the state information of the electronic device 100 provided through the first and second input/ output module 220, 230 by using touch. Also, the third input/output module 240 can provide images corresponding to the operating state of the electronic device 100 by using the light emitted from the direct type or edge type light emitting modules.
Figs. 58-60 illustrates an example in which the operation of the air conditioner is controlled in the electronic device 100 according to the present invention, which is implemented through air conditioner, based on the touch on the input/output module 200.
It can be seen in Fig. 58 that the desired temperature of the air conditioner 100 is set by the first input/output module 220 of the input/output module 200. In other words, the controller 120 of the air conditioner 100 can change the operating state of the air conditioner 100 based on at least one of the location and movement of the touch received through the touch sensing module (not illustrated) of the first input/output module 220.
At this step, the controller 120 of the air conditioner 100 can control at least one of the color and intensity of the light emitted from the light emitting modules included in the first input/output module 220 so that the color provided through the first input/output module 220 approaches the blue light as the desired temperature set by the touch is low. Then the user can intuitively recognize the desired temperature set by the user by observing the color of the light provided through the first input/output module 220.
Also, referring to Fig. 58, it can be seen that the user can set the intensity of the wind of the air conditioner through the touch on the second input/output module 230. In this case, the controller 120 of the air conditioner 100 can control the light emitting operation of the light emitting module included in the second input/output module 230 so that the color of the light provided through the second input/output module 230 becomes deeper as the set intensity of wind becomes strong. Then the user can intuitively recognize the desired wind intensity set by the user by observing the color of the light provided through the second input/output module 230.
Fig. 59 illustrates that the third input/output module 240 prepared in the crossing area of the first and second input/ output modules 220, 230 can serve as a separate means for inputting information. More specifically, in Fig. 59, the controller 120 performs the function of air cleaning of the air conditioner 100 as the user touches the third input/output module 240, and an image representing the air cleaning function is displayed through the third input/output module 240.
Although not illustrated in Fig. 59, the controller 120 can output, when the user touches the third input/output module 240 again, an image of thermometer corresponding to the temperature information provided through the first input/output module 220. Also, when the user touches the third input/output module 240 again, the controller 120 can output an image corresponding to the wind intensity information provided through the second input/output module 230.
In this case, in order to provide multiple images, the third input/output module 240 can be implemented by the structure including light emitting modules emitting lights of different wavelength bands and emitting patterns which emit light of specific wavelength band in response to the lights of different wavelength bands, as illustrated in Fig. 50. However, the present invention is not limited to this structure.
Fig. 60 illustrates the process in which the input/output module 200 performs the function of cleaning in the air conditioner 100, and the information on the wind intensity and desired temperature set up by the user is provided.
It has been shown in the above description with reference to Figs. 53-60 that the bar-type input/output module pair can cross each other in the shape of cross. However, the present invention is not limited to this structure. For example, the crossing input/output module pair can be a curve rather than a line, and the crossing of the input/output module can be in other shapes other than the cross. Also, the number of crossing input/output modules is not limited to 2.
The method of information input and output in the electronic device 100 according to the present invention as described above can be implemented by computer programs in the way that can be performed by using various computer means, and recorded in computer-readable record media. The computer-readable record media can include the program commands, data files and data structures in a single structure or combination of many structures. The programs to be recorded in the media can be specially designed and constructed for the present invention, or publicly known programs in the field of computer software.
Examples of computer-readable recording media include magnetic media such as hard disk, floppy disk and magnetic tape, optical media such as CD-ROM and DVD, magneto-optical media such as floptical disks, and other hardware devices specially designed to store and execute program commands such as ROM, RAM and flash memory. Examples of programs include machine language codes generated by compilers and high level language codes that can be executed on the computer by using interpreters. The hardware devices for the operation of the present invention can be implemented by one or more of software modules, and the reverse is also possible.
Although the present invention has been described for limited embodiments with reference to drawings, the present invention is not limited to the embodiments described above, and those skilled in the art of the present invention will be able to make correction or modification from the description of the present invention.
Therefore, the scope of the present invention should not be limited to the examples described above, and should be interpreted by the claims attached and equivalents thereof.
