Description

Description Lighting device and computer-mounted device

The present invention relates to a lighting device for controlling lighting (lighting) of a plurality of lighting means and a device mounted with a combination, for example, a sub-device provided on the back of a foldable mobile phone or the like.

The present invention relates to a lighting device and a computer-mounted device that are used when, for example, simultaneously controlling the LCD display switching button (back key) and the lighting (illumination) of a sub LCD. Background art

At present, the number of foldable mobile phones is increasing, but in recent years, such mobile phones have not only the main liquid crystal display screen (main LCD) but also the state of the phone even when folded. Some of them have a sub LCD on the back so that they can be confirmed.

In addition, some models have a sub-LCD display switching button (back key) together with the sub-LCD on the back of the mobile phone.

Also, the rear keys are equipped with light emitting diodes (LEDs), which may be used to blink the rear keys themselves in various colors or to continuously change the illumination color. In addition, during the lighting and blinking of the rear key, the sub LCD is normally used to maintain the lighting state. In such a mobile phone, when the sub-LCD is kept lit while the back key is blinking, the back key and the illumination of the sub-LCD must be controlled completely differently.

FIG. 11 is a block diagram schematically showing a hardware configuration of a mobile phone 200 based on the conventional technology. In the figure, a radio transmission / reception unit 2 having an antenna 1 for receiving radio waves, a baseband processing unit 3, an input operation unit 5 for a user to input a telephone number and information by a key operation, and a registration unit 6 A memory 6 having an a and a history section b and a display section 7 are connected to a control section 40. Further, a speaker 10 and a microphone 11 are connected to the control section 40 via an interface (IF) 9. It is connected to the. The display unit 7 is connected to a main LCD display unit 7a for displaying on the main LCD 21 and a sub LCD display unit 7b for displaying on the sub LCD. The display a and b are controlled by the display unit.

As for the illumination control function for the sub LCD and the rear keys, as shown in the figure, the sub LCD illumination section 12 for illuminating the sub LCD and the rear key illumination section 13 for illuminating the rear keys are separately connected to the control section 40. The lighting control of the sub LCD and the back keys is performed separately.

FIG. 12 is a circuit diagram showing lighting control of the sub LCD and the back key by the control unit 40, the sub LCD lighting unit 12, and the back key lighting unit 13 in FIG. In this circuit diagram, the LEDs used for the rear keys are three colors of R (red), G (green), and B (blue), and a combination of these three colors enables emission of seven colors. In FIG. 12, the sub LCD lighting section 12 is composed of a sub LCD LED 830, a current limiting element 840, and a switching element 850. The switching element 850 is connected to the sub LCD LED control output port 401 of the control unit 40, and is turned on by the output of a control pulse from the sub LCD LED control output port 401, and the sub LCD LED 830 emits light. .

Further, the rear key illumination unit 13 includes a rear key LED (R) 800r, an R LED, a current limiting element 810r, and a switching element 820r. One-way LED (G) 800 g, current limiting element 810 g, switching element 820 g, also for B, rear key LED (B) 800 b, current limiting element 810 b, switching element 820b. The respective switching elements are connected to the LED (R) output port 40r, the LED (G) output port 40g, and the LED (B) output port 40b of the control unit 40, and are connected to these ports. Turns on by the output of a control pulse, and the LED corresponding to each port emits light when current flows from the power supply side.

As described above, in the conventional configuration and method, the mobile phone 200 provided with the rear keys and the sub LCD necessarily needs both the control keys for the rear keys and the sub LCD. Only the number of control components is required. Therefore, in the conventional configuration and method, the number of control ports is reduced, the number of parts is reduced, and the size and the size are simplified. Conversion. Moreover, it is difficult to realize cost reduction.

The present invention has been made to solve such a problem, and it is an object of the present invention to realize a state that can be regarded as a blinking state by alternately lighting lights of different colors on a rear key. Therefore, the control port for the sub-CD and the control port for the rear key can be made common, so that the lighting and blinking of the sub-LCD and the rear key can be controlled with a smaller number of ports compared to the past. It is an object of the present invention to provide a lighting device and a computer mounted device that can be performed, and thus can be simplified and reduced in size and cost. Disclosure of the invention

The present invention is directed to a first illumination which obtains a plurality of types of first illumination light by combining respective light emissions of at least two light emitting means, each of which is independently turned on and off. Means for obtaining second illumination light by another light emitting means different from the light emitting means; and performing on / off control of at least two light emitting means in the first lighting means; A lighting device comprising: lighting control means for turning on the light emitting means in the second lighting means to emit light when at least one of the two light emitting means is turned on to emit light. It is.

According to such a configuration, even if the lighting color of the first lighting means is changed, the lighting state of the second lighting means can be maintained. For example, the lighting colors of the first lighting control are alternated. The lighting state of the second illuminating means can be maintained by switching to, and building the pseudo blinking state. As a result, control efficiency is increased, the hardware configuration required for control can be simplified, and the cost of the lighting device can be reduced.

In the embodiment of the present invention, the first illuminating means functions to illuminate the back key of the foldable mobile phone, and the light emitting means is composed of a three-color RGB back key LED. The second illuminating means functions to illuminate the sub LCD, and the light emitting means is composed of a sub LCD LED. The lighting control means includes a control unit, a control port for RGB three colors (output port for LED), and switching for each of the three colors. It consists of an element, a switching element for the sub LCD, and an OR circuit. This OR circuit calculates the logical sum of the control ports of the three colors RGB to emit light (the sub LCD LED in the embodiment) in the second illumination means (illuminates the sub LCD in the embodiment). Outputs control signal.

Therefore, for example, when performing lighting control of the back LCD and the sub LCD of a mobile phone, the lighting control of the sub LCD can be performed only with a plurality of control ports provided for the back LCD. The number of control ports is small, and the rear keys and sub LCD can be controlled simultaneously, increasing control efficiency.

Further, in the lighting device according to the present invention, the lighting device further includes a mode setting means for setting an illumination mode (for example, a mode in which blinking, lighting, emission color, and the like are set) in the first lighting means, Accordingly, the illumination control means can perform on-Z off control for each of the at least two light-emitting means (in the embodiment, the three-color RGB rear-surface LED). According to such a configuration, it is possible to illuminate with various illumination methods by the first illumination means, so that the illuminations of the first illumination means and the second illumination means are controlled without limiting the illumination method. be able to. Further, in the lighting device according to the present invention, when the mode setting means sets the lighting color of the first lighting means to a continuously changing mode, the at least two lighting modes in the first lighting means are changed. The timing of turning off the light emitting means to be turned off by the lighting control means in order to change to the next illumination color is after turning on the light emitting means to be turned on. For this reason, the second lighting means always illuminates while the first lighting means is illuminating, and the illumination of the second lighting means is not interrupted even when the illumination color is switched in the first lighting means. Lighting can be maintained. In the present embodiment, even if the illumination color of the rear key changes continuously, one of the LEDs for the rear key is always on, so that the illumination of the sub LCD is not discontinuously interrupted. Will be maintained.

Furthermore, when the first lighting means is in the blinking mode, in the embodiment of the present invention, a three-color RGB LED is used as the light emitting means of the back key, and white light obtained by turning on all of these is used. Turn on one or two of these LEDs to emit light other than white light. According to such a configuration, the first lighting means alternately emits light of white light and a color other than white light, so that a pseudo blinking state can be provided while the first lighting means is always on. The flashing state of the first lighting means can be realized without interrupting the lighting by the first lighting means. Specifically, if the sub-LCD is kept lit while the back key of the mobile phone is blinking, the conventional method, for example, if it is set to blink red, “red—off—red → off” —Control is performed so that “red → goes out”. However, by using the method of the present invention, by setting this unlit portion to white, it is possible to maintain a state in which the back key is always turned on and the red flashes visually. Becomes possible.

Furthermore, the present invention relates to a computer-mounted device having a button key and an LCD, wherein the computer-mounted device has the same function as the lighting device described above, and is mounted on various computers. In the lighting control for the lighting means, it is possible to efficiently perform the lighting control without deteriorating the performance of the conventional lighting while simplifying the hardware configuration.

The back key 22 is not only lit and blinking as described above, but also can be used to switch the display on the sub LCD 23 or start memo recording by pressing. Can be.

FIG. 2 is a block diagram schematically illustrating an example of a hardware configuration of foldable mobile phone 20 (hereinafter, mobile phone 20) according to the embodiment of the present invention. In the figure, a wireless transmission / reception unit 2 having an antenna 1, a baseband processing unit 3, an input operation unit 5 for a user to input a telephone number and information by key operation, a registration unit 6a and a history unit 6 A memory 6 having b and a display unit 7 are connected to the control unit 4, and a speaker 10 and a microphone 11 are connected to the control unit 4 via an interface (IF) 9. The display unit 7 includes a main LCD display unit 7a for performing display on the main LCD 21 in FIG. 1 and a sub LCD display unit 7b for performing display on the sub LCD 23 in FIG. The display units 7 a and 7 b are connected and are controlled by the display unit 7.

Further, as a characteristic configuration different from the conventional technology, a sub LCDZ rear key illuminating section 8 for simultaneously controlling both the function of illuminating the sub LCD 23 and the function of illuminating the rear key 22 without separately providing the function is provided. The sub-LCD / rear key illumination unit 8 is connected to the control unit 4.

FIG. 3 is a circuit diagram showing illumination control of the sub LCD 23 and the rear key 22 by the control unit 4 and the sub LCDZ rear key illumination unit 8 in FIG. As with the circuit diagram based on the conventional technology (Fig. 12), the LEDs used for the rear panel 22 are three colors of RGB, and a combination of these three colors enables emission of seven colors. The sub LCD / rear key illumination section 8 in Fig. 3 has a rear key LED (R) 80r, which is an R LED, and a current limiting element for illuminating the rear key 22. 81 r, switching element 82 r, LED for rear key L (G) 80 g for G, current limiting element 81 g, switching element 82 g, and LED for B for rear key LED (B) 8 Ob, current limiting element 8 lb, and switching element 82 b. Each switching element is connected to the LED (R) output port 4r, LED (G) output port 4g, and LED (B) output port 4b of the control unit 4.The output of control pulses from these ports Turns on, and current flows from the power supply to the LED corresponding to each port to emit light.

The configuration for illuminating the sub LCD 23 includes a sub LCD LED 8 3, a current limiting element 84, and a switching element 85.In addition, OR circuits 86, 87 for ORing control signals output from the respective LED output ports of the control unit 4 are provided. I have. The switching element 85 is turned on and off by the result of the logical sum of the OR circuits 86 and 87. As is clear from this circuit diagram, if any of the switching elements 82 of the rear key LEDs 81r, 81g, and 81b is turned on by a control signal from the control unit 4, the switching of the sub LCD LED 83 is performed. The element 85 is turned on. That is, while the back key 22 is lit, the sub LCD 23 is also lit.

Here, FIG. 4 shows a correspondence table between the combinations of the output ports 4b, 4g, and 4r for the RGB three-color LED and the coloring. As shown in the table, for example, the rear key 22 turns off when all the RGB output ports are turned off, and the rear key 22 lights white when all the RGB output ports are turned on. Depending on the combination of the ports, blue, green, red, light blue, purple, and yellow can be developed in addition to white.

FIG. 5 shows the output ports for each LED in the control unit 4 when the illumination color of the rear key 22 continuously changes to “red-blue-yellow-light blue” based on the correspondence table of FIG. FIG. 9 is a diagram showing details of control on ports 4b, 4g, and 4r in a time chart.

(1) First, when the LED is off, all LED output ports are off (red: 0, green: 0, blue: 0).

(2) When the rear key 22 is lit in red, the control unit 4 turns on the LED (R) output port 4 r (red: 1, green: 0, blue: 0).

(3) When changing to blue next, turn on the port to be turned on before turning off the port to be turned off. Here, turn on the output port 4b for LED (B) (red: 1, green: 0, blue: 1).

(4) Then, turn off the LED (R) output port 4r (red: 0, green: 0, blue: 1). As a result, the back key 22 emits blue light.

(5) Next, when changing from blue to yellow, first set the output port 4 r for LED (R) and the output port 4 g for LED (G) to 〇N (red: 1, green: 1, blue : 1 (6) Then, turn off the output port 4b for LED (B) (red: 1, green: 1, blue: 0). As a result, the rear key 22 emits yellow light.

(7) Next, when changing from yellow to light blue, first turn on the LED (B) output port (red: 1, green: 1, blue: 1).

(8) After that, turn off the LED (R) output port 4r (red: 0, green: 1, blue: 1). As a result, the rear key 22 emits light blue.

The time between (3)-(4), (5)-(6), (7)-(8) is the time (change point) during which the previous color and the next color are overlapped. The section 4 performs high-speed control so that the user of the mobile phone 20 does not become aware of the change point.

While the back key 22 is lit, even if the illumination color changes as described above, any of the three LED output ports 4b, 4g, and 4r is set to 〇N. Is always ON, and the sub LCD 23 can keep lighting. Next, examples of various illumination patterns of the back key 22 will be described with reference to a time chart similar to FIG.

FIG. 6 shows the output ports 4 b, 4 g, and 4 g for each LED in the control unit 4 when the rear key 22 flashes in a set color, for example, when a voice call arrives from the mobile phone 20 or when the alarm timer is activated. FIG. 4 is a diagram showing details of control for 4r in a time chart. In the present embodiment, the user can arbitrarily set the illumination color of the back key 22 and the control unit 4 controls each LED output port according to the setting.

(1) First, when the LED is off, all LED output ports are OFF (red '0, green: 0, blue: 0).

(2) When an incoming call occurs, if the setting color of the back key 22 blinking is red, the control unit 4 sets the LED (R) output port 4 r to 〇N (red: 1, green: 0, Blue

: 0). This state is maintained for 1000ms.

(3) After the lapse of 1000 ms, turn on all the LED output ports to make the rear key 22 turn white. Here, turn on the output port 4g for LED (G) and the output port 4b for LED (B) (red: 1, green: 1, blue: 1). As a result, the rear key 22 emits white light. This state is maintained for 500ms.

(4) After that, repeat (2) and (3). With this, the lighting color of the rear key 22 Changes continuously as “red—white → red → white...”, So that the back key 22 appears to blink in a pseudo manner. Similar to FIG. 5 described above, the back key 22 is not actually turned off during the pseudo blinking, so that the sub LCD 23 keeps the lighting state. .

FIG. 7 is a time chart showing a control method in the case where the illumination color of the back key 22 is continuously changed every seven seconds in seven colors, for example, during a call of the mobile phone 20 or the like.

(2) When a call is started, the control unit 4 turns on all the LED output ports (red: 1, green: 1, blue: 1) so that the rear key 22 is colored white. Maintain this state for 2 s.

(3) Next, to change from white to light blue, turn on the port to be turned on before turning off the port to be turned off. However, there is no change here because all ports are ON.

(4) After that, turn off the LED (R) output port 4r (red: 0, green: 1, blue: 1). As a result, the back key 22 emits light blue.

(5) After the lapse of 2 s, turn on the port to be turned on before turning off the port to be turned off in order to change from blue to blue next time. However, there is no change here because the ports to be turned on are already on.

(6) After that, turn off the output port 4g for LED (G) (red: 0, green: 0, blue: 1). As a result, the back key 22 emits blue light.

(7) After 2 seconds, turn on the LED (G) output port 4g (red: 0, green: 1, blue: 1) to change from blue to green.

(8) After that, turn off the output port 4 b for LED (B) (red: 0, green: 1, blue: 0). As a result, the rear key 22 emits green light.

(9) After 2 s, turn on LED (R) output port 4r (red: 1, green: 1, blue: 0) to change from green to yellow. As a result, the rear key 22 emits yellow light.

(10) After that, the ports that should be turned off are turned off. There is no change because the port is already off.

(1 1) After 2 seconds, turn on the port to be turned on. However, there is no change here because the port to be ON is already ON.

(12) Then turn off the output port 4 g for LED (G) (red: 1, green: 0, blue: 0). As a result, the rear key 22 emits red light.

(13) Next, to change from yellow to red, turn on the output port 4b for LED (B) (red: 1, green: 0, blue: 1). As a result, the rear key 22 emits purple light.

(14) After that, the port to be turned off is turned off, but here, the port to be turned off is already off, so there is no change.

(15) After that, repeat (2) to (14). As a result, the illumination color of the back key 22 continuously changes to seven colors. Similar to FIG. 5 described above, the back key 22 is not turned off even at the change point of the illumination color, so that the sub LCD 23 keeps the lighting state. By applying the pseudo-blinking control shown in FIG. 6, for example, when a mail is received, the set color and white can be repeatedly generated in a predetermined pattern. FIG. 8 is a time chart showing an example of such a pattern repetition. As shown in the figure, pattern 1 is composed of a set color of 400 ms, a white color of 200 ms, and a set color of 400 ms, and this configuration is repeated. This process can be realized by using the pseudo blinking control method shown in FIG.

Such blinking and color change patterns may be preset in the mobile phone 20 or may be arbitrarily set by the user on the mobile phone 20. The embodiment of the present invention has a function that allows the user to arbitrarily set the blinking color when controlling blinking when receiving a voice call, wake-up, receiving a mail, or the like. FIG. 9 is a display example of a setting screen for allowing the user to arbitrarily set the illumination color of the back key 22. The user can selectively set the emission color from the seven emission colors, and the control unit 4 controls ON / OFF of each LED output port based on the set color.

As shown in the figure, first display the system setting menu 100 and select “7. Next, a back light setting screen 101 is displayed. This The color currently set in the item to be set is displayed on the screen. The user selects the item to be set and sets the color. Select “Voice Incoming” to set the color for incoming voice calls. Next, a color arrangement selection screen 102 is displayed. On this screen, select and set the desired color. Immediately after the color selection screen 102 is displayed, the currently set color is displayed inverted. In the figure, “blue” is inverted as the currently selected color. The user inverts the color to be newly set by operating the keys of the mobile phone 20 and determines the color. As a result, the color set for the incoming voice call is set.

To set another item's setting color, return to the backlight setting screen 101. For example, if the user wants to set the color for receiving mail, the user selects “mail reception” (103), and displays a color selection screen 104 for setting the color for receiving mail. Similarly to the above, in the figure, the currently set “green” is inverted. The user inverts the color to be newly set by operating the keys of the mobile phone 20 and confirms it. Thereby, the setting color at the time of mail reception is set.

Similarly, if you want to set the color for the wake-up item, select the item of “Wake-up” on the backlight setting screen (105), and set it on the color selection screen 106 as well.

FIG. 10 shows an example of various functions executed by pressing the back key 22 in the mobile phone 20 according to the embodiment of the present invention. As shown in the figure, the function executed differs depending on the open / close state and the operation state of the mobile phone 20. For example, when the back key 22 is short-pressed while the mobile phone 20 is closed and in a standby state, the display of the sub LCD 23 is switched, and when the key is long-pressed, an inquiry for an incoming mail is performed.

Further, in the present embodiment, the rear keys are illuminated by LEDs of three colors of RGB, but of course, the keys may be illuminated by two colors of LEDs, and the number is not limited. Further, the blinking time and the order of the change of the illumination color, or the timing, etc., described above are examples of implementing the present invention, and the user can arbitrarily set the illumination mode. Alternatively, the present invention may be set in advance in the mobile phone main body, and may be appropriately applied without departing from the spirit of the present invention. Furthermore, in the above-described embodiment, the lighting control in the mobile phone has been described. However, it is needless to say that the present invention is not limited to the mobile phone, but can be applied to, for example, a PDA or another computer device. . Industrial applicability

As described above, according to the present invention, for example, the sub LCD provided on the back of the mobile phone and the back key are controlled simultaneously using the same control port. The configuration can be simplified, and the cost of the lighting device can be reduced. Therefore, even when the number of control ports is limited in the manufacture of mobile phones, it is very useful because the number of ports for controlling the illumination of the rear keys is sufficient.

In addition, since the control port to be turned on is turned on and then the control port to be turned off is turned off at each control port of the LED on the rear key, even if the illumination color of the rear key changes continuously, One of the key LEDs is always on, and the sub LCD illumination is maintained without interruption. In addition, when the back key blinks, it can be turned on and off in a simulated blinking state even though it is always on, by alternately emitting white light and a color other than white light. Even in the state, the lighting of the sub LCD can be maintained without interruption. In this way, compared to the conventional method in which the rear key and sub-LCD lighting are controlled separately, the number of control ports and the number of control parts can be controlled in the same manner as before using a mobile phone, PDA or computer device. Etc. can be configured.
