(Implementation type 1)

Fig. 1 is a perspective view of a display device of an embodiment 1. In the first drawing, reference numeral 1 denotes a display device. As shown in the figure, the display device 1 includes a rectangular liquid crystal panel 2 and a backlight device 3 (see FIG. 2), wherein the rectangular liquid crystal panel 2 has a display surface 2a. The backlight device 3 is irradiated with light on the liquid crystal panel 2 from the side opposite to the display surface 2a. Further, the display device 1 is provided with a leg portion 10 which is supported by one of the long sides of the liquid crystal panel 2. The display device 1 is provided by placing the leg portion 10 on the lower side, placing it on a flat table surface, and setting the display surface 2a to the front side. Hereinafter, the display device 1 will be described in the up and down direction and the front and rear direction in the use state.

Inside the display device 1, a tuner 11 that receives a broadcast wave from an antenna and a decoder 12 that decodes the encoded broadcast wave are provided, and the display device 1 is assembled as a television receiver. The display device 1 is provided with a covering board 4 which can cover the entire lower side of the display surface 2a and includes a light guide body which will be described later.

Fig. 2 is a schematic partial oblique sectional view of the display device 1. Fig. 3 is a cross-sectional view taken along line III-III of Fig. 1. The backlight device 3 is provided with a chassis 30 having a rectangular bottom plate and side plates respectively rising from the four sides of the bottom plate. The chassis 30 is a shallow bottom box type in which an opening is provided on the liquid crystal panel 2 side.

A plurality of LEDs (not shown) are provided in parallel on the bottom plate of the chassis 30, and the LEDs are exposed on the front side from the reflection sheet 33 covering the entire inner surface of the chassis 30. The liquid crystal panel 2 is provided on the opening side of the chassis 30, and is provided to face the bottom plate by the panel chassis, and a rectangular diffusion plate 34a and an optical sheet 34b are disposed between the liquid crystal panel 2 and the chassis 30.

The peripheral portion of the display surface 2a of the liquid crystal panel 2 is covered by the shutter 5. The baffle 5 has a square-shaped front plate 5a and a side plate 5b standing perpendicularly to the outer peripheral edge of the front plate 5a. The front plate 5a of the baffle 5 covers the peripheral portion of the liquid crystal panel 2 via a separator. The side plates 5b of the shutter 5 are fixed to the side plates of the chassis 30 by screws, for example.

The cover panel 4 is a member having an L-shaped cross section, and has a rectangular front panel 4a and a side panel 4b standing upright on one of the long sides of the front panel 4a. The front plate 4a has a curved portion 40 which is located at the central portion and is curved to protrude from one side. The cover panel 4 is mounted such that the bent portion 40 protrudes from the front side of the liquid crystal panel 2 and faces the lower side portion of the shutter 5. A space is formed between the curved portion 40 and the front surface of the baffle 5.

4 is a front perspective view of the light guide 6, and FIG. 5 is a rear perspective view of the light guide 6. The light guide body 6 is made of glass or a transparent resin, and has a first surface 61, a second surface 62 continuing the first surface, a third surface 63 continuing the second surface, and the first surface and the first surface. The fourth face 64 of the third face.

The second surface 62 has a long rectangular shape in one direction, and the first surface 61 and the third surface 63 extend in the same direction from the long sides of the second surface 62, respectively. The fourth face 64 is approximately parallel to the second face 62. The angle formed by the first surface 61 and the second surface 62 and the angle formed by the second surface 62 and the third surface 63 are acute angles. The angle formed by the first surface 61 and the second surface 62 is larger than the angle formed by the second surface 62 and the third surface 63. Further, the width of the third surface 63 and the first surface 61 extending outward from the second surface 62 is gradually reduced from the center in the longitudinal direction toward the both ends. Thereby, the light guide body 6 has a shape along the curved portion 40.

The second surface 62 has a concavo-convex portion 62a formed by embossing. The uneven portion 62a is a portion other than both end portions in the longitudinal direction of the second surface 62. Further, the uneven portion 62a may be formed on the entire surface of the second surface 62. The first surface 61 is formed into a pear-like shape. Further, the fourth surface 64 is dyed black. The uneven portion 62a can be easily formed on the second surface 62 by embossing.

The light guide body 6 is located below the peripheral portion of the display panel 2 and between the curved portion 40 of the cover panel 4 and the front surface of the shutter 5 such that the first surface 61 faces upward and the third surface 63 faces downward. It is configured in a manner and is sandwiched by the covered panel 4 and the baffle 5. Therefore, the first surface 61 extends forward with respect to the display surface 2a. Further, the first surface 61 is exposed to the outside between the curved portion 40 and the baffle 5.

The second surface 62 of the light guide body 6 is in contact with the front surface of the baffle 5 and along the display surface 2a. The fourth surface 64 is in contact with the rear upper end side of the curved portion 40 of the covering panel 4. The light guide body 6 is attached to the cover panel 4 by attaching the fourth surface 64 to the rear surface of the curved portion 40 by, for example, a double-sided tape.

The LED substrate 70 is disposed below the light guide 6, and the LED substrate 70 is fixed to the cover panel 4. On the LED substrate 70, an LED 71 is mounted at a position facing the third surface 63 of the light guide 6. The LED 71 is illuminated upwards. Here, since the cover plate 4 covers the light guide 6, the LED substrate 70, and the LED 71 from the front surface, the appearance of the display device 1 can be improved.

Fig. 6 is a schematic view showing the progress of light, and Fig. 7 is a view showing the range of emitted light. As shown in FIG. 6, the light emitted from the LED 71 is refracted rearward via the third surface 63, enters the light guide 6, reaches the second surface 62 side, and is reflected obliquely forward through the second surface 62. The light reflected by the second surface 62 reaches the first surface 61, and is then emitted to the outside from the first surface 61. Since the second surface 62 has the uneven portion 62a, the light reaching the second surface 62 is diffused and reflected in the longitudinal direction and the width direction (up-and-down direction) of the light guide 6.

The first surface 61 is located on the front side of the display surface 2a, and is inclined obliquely downward in a forward state. Therefore, the light reaching the first surface is refracted on the front side. At this time, the light emitted from the first surface 61 is refracted on the first surface 61, and becomes upward and forward. Here, since the angle formed by the first surface 61 and the second surface 62 is an acute angle, the light emitted from the first surface 61 is hard to be reflected on the display surface 2a. Further, since the first surface 61 is formed into a pear-like shape, the light emitted from the light guide body 6 has a soft feeling.

A part of the reflected light passing through the second surface 62 reaches the fourth surface 64, but the fourth surface is black and is absorbed. Further, the fourth surface 64 may not be colored black. In this case, it is only necessary to prevent reflection of light behind the curved portion 40 of the covering panel 4. Further, the first surface 61 may not be formed in a pear shape.

The light diffused on the second surface 62 travels not only in the vertical direction but also in the longitudinal direction of the light guide body 6. Therefore, it can be seen from actual observation that the light emitted from the light guide body 6 is diffused around the central portion in the longitudinal direction of the light guide body 6 as indicated by the hatched portion in FIG. As the gradual decline occurs, the center portion of the light guide body 6 in the longitudinal direction becomes bright, and the both ends are darkened. Further, since the light guide body 6 is disposed below the peripheral portion of the display panel 2, the light emitted from the light guide body 6 is diffused from below the peripheral portion of the display panel 2.

The light from the LED 71 is emitted from the light guide 6 as described above. Therefore, the user of the display device 1 can clearly recognize the reflected light on the second surface 62 by peeking the first surface 61 of the light guide body 6 from the upper side. Further, since the second surface 62 is located along the display surface 2a and on the extending portion of the display surface 2a, the user of the display device 1 can recognize that the second surface 62 is connected to the display surface 2a to emit light.

Here, the angle formed by the second surface 62 and the third surface 63 is preferably 35 degrees or more and 60 degrees or less, whereby the refraction of light passing through the third surface 63 is improved, and the range of the emitted light is changed. Good.

The range of the light emitted from the light guide 6 can be changed by changing the angle formed by the second surface 62 and the third surface 63. Fig. 8 is a schematic view showing the shape of the light guide body 6. The shape of the light guide body 6 can be changed in accordance with the display device 1. For example, it can be designed as shown in Figs. 8A to 8C.

In the light guide body 6 of FIGS. 8A to 8C, the width L1 of the second surface 62 is the same, and is 12.8 mm. On the other hand, in the light guide body 6 of Fig. 8A, the angle θ1 between the second surface 62 and the third surface 63 is 42.5 degrees, and in the light guide body 6 of Fig. 8B, the third surface 63 and the third surface The angle θ2 formed by the two faces 62 is 35.0 degrees. In the light guide body 6 of Fig. 8C, the angle θ3 formed by the third face 63 and the second face 62 is 60.0 degrees.

Figure 9 is a schematic diagram showing the range of emitted light. Fig. 9A shows a case where the light guide body 6 of Fig. 8A is used, Fig. 9B shows the case where the light guide body 6 of Fig. 8B is used, and Fig. 9C shows the use of Fig. 8C. The case of the light guide 6. The range of the emitted light shown in FIG. 9A is W1 in the longitudinal direction of the light guide 6, and the range of the emitted light shown in FIG. 9B is the width in the longitudinal direction of the light guide 6. W2 (W2 < W1), the range of the emitted light shown in FIG. 9C is W3 (W3>W1) in the longitudinal direction of the light guide 6.

As described above, the width L1 of the second surface 62 is made the same, and by narrowing the angle formed by the third surface 63 and the second surface 62, the range of the emitted light is reduced, and the third surface 63 is increased by The angle formed by the second surface 62 increases the range of the emitted light. Therefore, by fixing the width of the second surface 62 and adjusting the angle formed by the third surface 63 and the second surface 62, the range of the emitted light can be appropriately set.

Further, the range of the emitted light also changes in accordance with the width of the second surface 62. The width of the second surface 62 is changed in accordance with the design of the display device 1. However, by matching the width of the second surface 62, the angle between the third surface 63 and the second surface 62 is changed, and light can be emitted. The range is set to the same level. Fig. 10 is a view for explaining the shape of the light guide body. For example, the light guide body 6 is designed as shown in Figs. 10A to 10C. In the light guide body 6 of Fig. 10A, the width L1 of the second surface 62 is 12.8 mm, and the angle θ1 between the third surface 63 and the second surface 62 is 42.5 degrees. In the light guide body 6 of Fig. 10B, the width L2 of the second surface 62 is 14.9 mm, and the angle θ2 between the third surface 63 and the second surface 62 is 35.0 degrees. In the light guide body 6 of Fig. 10C, the width L3 of the second surface 62 is 10.7 mm, and the angle θ3 between the third surface 63 and the second surface 62 is 60.0 degrees.

When the light guide body 6 designed as shown in FIGS. 10A to 10C is used, the light-emitting range of the first surface 61 is equivalent. As described above, even if the width of the second surface 62 is different depending on the design of the display device 1, the angle between the third surface 63 and the second surface 62 is adjusted by blending the width of the second surface 62. The range of the emitted light can be adjusted to the same extent.

In the display device 1 configured as described above, the control of the operation is performed by a control unit (not shown). The user of the display device 1 can transmit an instruction to the control unit by, for example, operating an operation unit such as a remote controller (hereinafter referred to as a "remote controller") that communicates with the display device 1 by infrared rays.

By the operation of the control unit, the light emitted from the LEDs in the chassis 30 is diffused by the diffusion plate 34a, and is focused by the optical sheet 34b to be irradiated to the rear surface of the liquid crystal panel 2. The liquid crystal panel 2 modulates and transmits the incident light to display the screen on the front side, that is, the display surface 2a. The display device 1 receives the video by the tuner 11, and displays the video on the display surface 2a of the liquid crystal panel 2 based on the broadcast wave of the television broadcast decoded by the decoder 12, and functions as a television receiver. .

Further, the control unit controls the lighting of the LED 71 to be turned off, and controls the brightness and color of the LED 71. With the operation of the power switch, the selection of functions, the remote control such as volume adjustment, and the like, the LED 71 is turned on and off, and the brightness or color of the LED 71 is changed. In these cases, according to the display screen displayed on the display surface 2a by the display panel 2, various expressions can be performed. Therefore, it is possible to cause an overall feeling between the light emitted from the light guide body 6 and the screen displayed on the display panel 2, and the user can be made aware of it.

The first surface 61 is disposed on the peripheral portion of the display surface 2a, and extends forward relative to the peripheral portion. Thereby, for example, by displaying a bright screen on the center of the lower end portion of the display surface 2a, the lower end portions of the first surface 61 and the display surface 2a appear to emit light without seams. Therefore, it is possible to cause an overall feeling between the light emitted from the first surface 61 and the screen indicated by the liquid crystal panel 2.

Further, in the light guide 6, the light from the LED 71 is diffused and reflected on the second surface 62, and is emitted from the first surface 61. Since the emitted light is the reflected light passing through the second surface 62, in addition to traveling upward, it also spreads and travels to the front side. Therefore, it is possible to prevent the deterioration of the picture quality caused by the light emitted from the light guide body 6. The light emitted from the light guide 6 has little influence on the screen of the display surface 2a, and does not cause interference. Further, the light emitted from the light guide body 6 can be softened by the pear skin surface of the first surface 61, and the overall feeling with the screen of the display surface 2a becomes good.

The width of the first surface 61 and the third surface 63 extending outward from the second surface 62 is gradually reduced from the central portion in the longitudinal direction toward the both end portions, and the curved portion 40 of the covering panel 4 covers the display panel 2. The light guide body 6 is included in the lower portion, and the curved portion 40 can also be designed to improve the design of the display device 1 along the shapes of the first surface 61 and the third surface 63. Further, the width of the first surface 61 and the third surface 63 extending outward from the second surface 62 may be constant in the longitudinal direction, and the light guide 6 may be capable of reflecting light passing through the second surface 62. If it is shot, it can be any shape.

(implementation type 2)

In the second embodiment, the shape of the light guide is different from that of the first embodiment. Figure 11 is a schematic partial cross-sectional view showing a display device of the embodiment 2. The configuration of the display device 1 of the second embodiment will be designated by the same reference numerals and will not be described in detail.

The display device 1 of the second embodiment is provided with a light guide 8. The light guide 8 has a first surface 81, a second surface 82, a third surface 83, a fourth surface 84, and a fifth surface 85. The third surface 83 and the second surface 82 have a long rectangular shape in one direction and are parallel to each other, and the third surface 83 and the second surface 82 are connected by a vertical connecting surface 85a. The second surface 82 is formed into a concavo-convex shape by embossing. Therefore, the second surface 82 of the embodiment 2 has the entire surface as the uneven portion.

The third surface 83 and the second surface 82 face the fourth surface 84, and the distance between the third surface 83 and the fourth surface 84 is long. The fourth surface 84 has a long rectangular shape in one direction. The first surface 81 is connected to the second surface 82 and the fourth surface 84 and has an acute angle with respect to the second surface 82.

The fifth surface 85 is connected to the fourth surface and is connected to the third surface 83 by the connection surface 85b. The contiguous surface 85b extends vertically outward from the third surface 83. The fifth surface 85 has an obtuse angle with respect to the fourth surface 84 and an obtuse angle with respect to the continuous surface 85b. Further, the angle formed by the fifth surface 85 and the second surface 82 is an acute angle.

The light guide 8 is located at the center of the lower side of the peripheral portion of the display surface 2a, and the second surface 82 is disposed to face the shutter 5. The third surface 83 is located outside the display surface 2a, and the LED 71 is disposed to face the third surface 83. The fourth surface 84 is in contact with the covering panel 4.

The light of the LED 71 is incident on the third surface 83, is reflected by the fifth surface 85, and reaches the second surface 82. The light reaching the second surface 82 is diffused and reflected on the second surface 82, and is emitted from the first surface 81. Even in this case, the light-emitting range and direction of the light guide body 8 are the same as those of the embodiment 1.

According to the configuration described above, since the light emitted from the first surface 81 of the light guide 8 is the reflected light of the second surface 82, the light emitted from the light guide 8 can be prevented. The resulting picture quality is low. Further, it is possible to cause an overall feeling between the light emitted from the light guide 8 and the screen displayed on the display panel 2, and the user can be made aware of it. Further, since the light guide body 8 is disposed on the peripheral portion of the display surface 2a, it does not interfere with the screen displayed on the display surface 2a, and the light emitted from the light guide body 8 is reflected between the screen displayed on the display surface 2a. The overall feeling will be good.

The angle formed by the second surface 82 and the fifth surface 85 is an acute angle, and by refracting the light incident on the third surface 83, the light can be favorably advanced to the second surface 82.

Further, in the first embodiment and the second embodiment, the second surface 62 or 82 may be formed by a mold having irregularities without being subjected to embossing, thereby forming an uneven shape.

Further, the number of LEDs facing the third surface 63 is not limited to one, and may be plural. In this case, a plurality of LEDs may be arranged along the longitudinal direction of the light guide body 6 on the LED substrate. In addition, LEDs of various illuminating colors can also be used in combination.

Further, the light guide body 6 may not be disposed on the peripheral portion of the display surface 2a, and may be disposed at an appropriate position in accordance with the design of the display device 1. Further, if it is possible to cover the lower portion of the peripheral portion of the display surface 2a, the cover member 4 may be covered with a cover member such as a plate or a block to cover the lower portion of the peripheral portion of the display surface 2a. The display device 1 of the implementation mode 1 and the implementation mode 2 may not be configured for a television receiver, but may be a display screen for information display, car navigation, or a personal computer.

(Implementation type 3)

Fig. 12 is a schematic front view of a display device of the embodiment 3. The configuration of the display device 1 of the embodiment 3 is the same as that of the embodiment 1 and will be denoted by the same reference numerals and will not be described in detail.

In the same manner as in the first embodiment, the display device 1 of the third embodiment includes a liquid crystal panel 2 having a display surface 2a, a backlight device 3, a cover sheet 4, a light guide 6, and an LED 71. The display device 1 is assembled as a television device in the same manner as in the first embodiment. Further, in Fig. 12, the illustration of the leg portion 10 is omitted.

The display device 1 receives the television broadcast signal and drives the liquid crystal panel 2 and the backlight device 3, whereby the first sound corresponding to the image can be output from the speaker while the image is output from the liquid crystal panel 2. The display device 1 can also acquire various information from the server via the Internet or the like.

In the third embodiment, the display device 1 outputs a second sound different from the television broadcast. The second sound is a user calendar or weather forecast downloaded by the Internet or the like. The LED 71 emits light corresponding to the second sound.

Figure 13 is a block diagram showing the structure of a display device. The display device 1 further includes a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, an antenna 150, a communication interface 160, a speaker 170, a microphone 180, and a GPS (Global Positioning System) 190. The camera 195, the connection unit 196, the audio signal output interface 197, and the timer 198.

The CPU 110 controls each part of the display device 1 by executing a program stored in the memory 120. For example, the CPU 110 executes various processes to be described later by executing a program stored in the memory 120 and referring to various materials.

The memory 120 is realized by various RAM (Random Access Memory), various ROM (Read Only Memory), and the like. The memory 120 stores a program executed by the CPU 110, a data generated by the CPU 110 executing the program, a correspondence relationship between the brightness and intensity/rhythm of the second sound and the light, and the like.

The liquid crystal panel 2 displays characters or screens as described in the first embodiment based on signals originating from the CPU 110. The LED 71 emits light in response to the signal from the CPU 110 in response to the second sound. By the light emission of the LED 71, light is emitted from the light guide body 6 in the same manner as in the first embodiment. This light is diffused and reflected by the second surface 62, and is emitted from the first surface. The light emitted from the first surface 61 of the light guide 6 has a light-emitting region 600 which is diffused downward from the peripheral portion of the display surface 2a as shown in Fig. 12.

The operation unit 140 receives an instruction from the service manager or the like and inputs the instruction into the CPU 110.

The antenna 150 receives a television broadcast signal or the like. More specifically, the display device 1 may have a connector capable of receiving a television broadcast signal from an outdoor antenna instead of the antenna 150.

The communication interface 160 transmits data from the CPU 110 to other devices such as a server via the Internet, a carrier network, a router, and the like. On the other hand, the communication interface 160 receives data from other devices such as a server via the Internet, a carrier network, a router, etc., and transmits the data to the CPU 110.

The speaker 170 outputs sound based on a signal originating from the CPU 110. The microphone 180 creates an audio signal based on the sound originating from the outside, and inputs it to the CPU 110. The GPS 190 acquires the current position of the display device 1 and transmits it to the CPU 110.

The camera 195 captures the outside of the display device 1 based on a signal originating from the CPU 110. The captured picture material is stored in the memory 120. The connecting portion 196 connects the display device 1 and an external device so that both parties can communicate with each other.

The audio signal output interface 197 is a speaker that outputs an audio signal to an external device, or a microphone, a headphone, a headphone, or the like. The timer 198 measures the time elapsed from the specified time, or measures the time remaining until the specified time, and transmits the time to the CPU 110. The display device 1 may further include a brightness sensor that detects the brightness of the display device 1 based on the signal from the CPU 110. The detection result is stored in the memory 120.

Fig. 14 is a flow chart showing the information processing of the display device 1. Figure 15 is a schematic diagram of sound analysis and light output. Next, the information processing of the display device 1 of the third embodiment will be described with reference to Figs. 14 and 15 . When the CPU 110 of the display device 1 outputs the second sound, the following processing is performed.

First, the CPU 110 analyzes the second sound as shown in Fig. 15 (step S102). The CPU 110 specifies a method of outputting light corresponding to the analyzed sound (step S104). For example, the intensity of the light is increased corresponding to a larger sound, or the intensity of the light is weakened corresponding to a smaller sound, or the brightness is set corresponding to a higher sound so that the color is close to red or corresponds to a lower sound. The brightness is set such that the color is close to blue, or the flickering rhythm is accelerated in response to a large change sound, or the flickering rhythm is slowed down in response to a small change sound.

The CPU 110 causes the speaker 170 to output a sound, and as shown in Fig. 14, the LED 71 is caused to emit light based on a predetermined output method (step S106).

In the display device 1 of the third embodiment, the light output from the first surface 61 of the light guide body 6 visually highlights the output of the second sound. Moreover, when the LED 71 is lit, the user can visually recognize that the information being output is not program information. Further, for example, if the received data includes information indicating importance, the greater the degree of importance of the information, the larger the CPU 110 displays it on the display surface 2a or the LED 71 is strongly illuminated.

According to the above configuration, it is possible to cause an overall feeling between the light emitted from the first surface 61 of the light guide 6 and the screen indicated by the liquid crystal panel 2.

(Implementation type 4)

Fig. 16 is a schematic front view showing a car navigation system as a display device of the fourth embodiment. The configuration of the display device 1 of the embodiment 4 is the same as that of the embodiment 1 and the embodiment 3, and the same reference numerals are used to omit the detailed description.

The display device 1 of the fourth embodiment is the same as the third embodiment, but the display device 1 of the embodiment 4 is assembled as a car navigation system. The display device 1 outputs car navigation information as the first sound while displaying the road guide. Further, the display device 1 outputs a second notification as a second sound by outputting another notification or speech. Even in the implementation mode 4, the display device 1 lights or turns off the LED 71 with respect to the second sound, and emits light from the light guide body 6 in the same manner as in the third embodiment. Thereby, the user can recognize that the second sound is being output.

According to the above configuration, it is possible to cause an overall feeling between the light emitted from the first surface 61 of the light guide body 6 and the screen displayed on the liquid crystal panel 2 constituting the car navigation system.

(implementation type 5)

Fig. 17 is a schematic view showing the outline of the operation of the display device of the fifth embodiment. The configuration of the display device 1 of the embodiment 5 is the same as that of the embodiment 1 and the embodiment 3, and the same reference numerals are used to omit the detailed description.

The display device 1 of the fifth embodiment has the same configuration as that of the third embodiment, and the other components of the electronic device such as the telephone 3002 or the washing machine 3003 are connected by the connection portion 196. Further, when the display device 1 outputs the sound data input by the telephone 3002 or the washing machine 3003, the display device 1 can also cooperate with the sound, and the light is output by the LED 71. Light emitted from the LED 71 is emitted from the light guide 6 in the same manner as in the third embodiment.

In addition, the electronic device is not limited to the telephone 3002 or the washing machine 3003, and may be a walkie-talkie, a microwave oven, an air conditioner, a refrigerator, a vacuum cleaner, an air cleaner, a humidifier, a dehumidifier, an electronic pot, a lighting fixture, etc.; AV (Audio/Video) equipment such as disc recorders, projectors, music players, etc.; residential lighting equipment such as vertical lighting, solar generators, water heaters, and warm water toilet controllers.

Thereby, it is possible to reduce the possibility that the user mistakes the notification issued by the electronic device as a sound in a television program such as a serial drama. In addition, by using the dialog box for notifying the notification from the electronic device, it is possible to prevent the image of the television program such as the serial drama from being obscured. In addition, the light emitted from the light-emitting surface 61 of the light guide body 6 visually highlights the motion of the external device.

(implementation type 6)

The display device 1 of the sixth embodiment has the same configuration as that of the third embodiment, and outputs light in a different manner for each operation. The configuration of the display device 1 of the embodiment 6 is the same as that of the embodiment 1 and the embodiment 3, and the same reference numerals are used to omit the detailed description.

Fig. 18 is a view showing the operation mode of the display device of the sixth embodiment. For example, the memory 120 stores the operation pattern database 125 as shown in Fig. 18. The operation mode database 125 includes a correspondence relationship between the activation trigger, the presence or absence of the synchronization screen, the color of the light, and the output method of the light in each operation, and the CPU 110 refers to the operation mode database 125 according to itself. The action or the surrounding environment causes the LED 71 to flash. Light is emitted from the light guide body 6 in the same manner as in the third embodiment by the light emission of the LED 71.

When the display device 1 is activated, a "wake up" action is performed. Specifically, when the display device 1 is activated, the CPU 110 causes the display surface 2a to slowly emit minute light, and the light starts the screen. In other words, the CPU 110 displays the image on the display surface 2a while gradually increasing the intensity of the LED 71.

The display device 1 performs a "sleep" operation when the power is turned off (OFF). Specifically, when the power of the display device 1 is turned off, the CPU 110 gradually reduces the light while making the screen disappear on the display surface 2a. In other words, the CPU 110 gradually weakens the image of the display surface 2a while gradually weakening the intensity of the LED 71.

When the display device 1 receives a command from the remote controller or the main body operating unit, the "reaction" operation is executed. Specifically, when an instruction is received by the remote controller or the main body operating unit, the CPU 110 causes the light to be instantaneously displayed on a part of the display surface 2a or causes the LED 71 to instantaneously emit light.

Fig. 19 is a schematic diagram showing the outline of the first operation of the display device 1 to change the volume. Fig. 20 is a schematic diagram showing the outline of the second operation of the display device to change the volume. When the display device 1 receives an instruction to change the volume, the "reaction (synchronization)" operation is executed. Specifically, when an instruction to change the volume is received by the remote controller or the main body operating unit, the CPU 110 displays a screen for indicating the volume on a part of the display surface 2a. More specifically, as shown in Figs. 19 and 20, the CPU 110 causes the semicircular indicator to be displayed on the left and right central portions below the display surface 2a. In other words, a plurality of strips representing the volume are arranged in a semicircle or a fan shape. Moreover, the larger the volume, the more the strips the CPU 110 will display from the left side to the right side on the display surface 2a.

Fig. 19 is a diagram showing the screen shift of the display surface 2a when an instruction for changing the volume is input once. Fig. 20 is a diagram showing the screen shift of the display surface 2a when an instruction for increasing the volume is continuously input. As shown in Fig. 19 and Fig. 20, the CPU 110 changes the number of the plurality of strips arranged in the radiation package in accordance with the volume after the change, like the speedometer of a car or the like on the display surface 2a.

More specifically, if the user presses the command to increase the volume once, the CPU 110 displays the indicator of the changed volume within a certain period of time, and then the indicator disappears. If the user presses the command to increase the volume again before the indicator disappears, the CPU 110 directly changes the display state without canceling the screen of the volume indicator. When the user long presses the command to increase the volume, the CPU 110 performs continuous change without canceling the screen of the volume indicator.

Here, each time the user presses a button for changing the volume, it is preferable that a part or all of the LED 71 or the display surface 2a is in a light-emitting state. Alternatively, during a period in which the user presses the button for changing the channel, it is preferable that a part or all of the LED 71 or the display surface 2a is in a light-emitting state.

In addition, the operation when the volume is lowered is the same as the operation when the volume is increased, and therefore the description will not be repeated.

Fig. 21 is a schematic diagram showing the outline of the first operation of the display device 1 to change the channel. Fig. 22 is a schematic diagram showing the outline of the second operation of the display device 1 to change the channel. Fig. 23 is a schematic diagram showing an outline of a third operation of the display device 1 to change channels. When the display device 1 receives an instruction to change the channel, the display device 1 performs a "reaction (synchronization)" operation. Specifically, when the CPU 110 receives an instruction to change the channel by the remote controller or the main body operating unit, the CPU 110 displays a screen or a character indicating the channel on a part of the display surface 2a. More specifically, as shown in FIGS. 21, 22, and 23, the CPU 110 displays the changed channel on the left and right center portions below the display surface 2a.

Fig. 21 is a diagram showing the screen shift of the display surface 2a when a designated channel command is input. The CPU 110 causes the display surface 2a to display the changed channel below, the changed channel or program information to be displayed above, and the entire screen to be completely black, and then display the changed channel image.

Fig. 22 is a diagram showing the screen shift of the display surface 2a when an instruction for bringing the channel upward is input. The CPU 110 causes the display surface 2a to display the screen indicating that the channel is up, and displays the changed channel or program information on the upper left side. After a certain period of time, the entire screen is switched to all black, and then the display is changed. Channel image.

Fig. 23 is a schematic diagram showing the movement of the screen of the display surface 2a when the button for pressing the channel up is pressed. The CPU 110 displays the screen on which the changed channel is displayed on the lower side of the display surface 2a, and displays the changed channel or program information on the upper left side. The CPU 110, while holding down the channel up button, switches the upper channel or program information while displaying the changed channel indicating the channel upward. If the channel up button is no longer pressed, the CPU 110 switches the entire screen to all black, and then displays the changed channel image on the display surface 2a.

Here, each time the user presses a button for changing the channel, it is preferable that a part or all of the LED 71 or the display surface 2a is in a light-emitting state. Alternatively, during a period in which the user presses the button for changing the channel, it is preferable that a part or all of the LED 71 or the display surface 2a is in a light-emitting state.

When the user speaks the display device 1, the display device 1 performs a "listening" operation. Specifically, when the microphone 110 detects the sound from the user, the CPU 110 blinks a part of the display surface 2a or the LED 71 at a constant rhythm like a beat.

The display device 1 performs a "suggested" action on the user. Specifically, the CPU 110 outputs the advice information to the user by the speaker 170, and a part of the display surface 2a or the LED 71 is initially outputted in a staggered manner, and then the light is weakened, and then gradually strengthened. The light of the standard color, for example, is preferably such that the light is gently flickered or it is repeated.

The display device 1 performs an operation of "speaking" to the user. Specifically, the CPU 110 outputs a dialogue with the user by the speaker 170, and causes a part of the display surface 2a or the LED 71 to blink in accordance with the rhythm of the dialogue. . For example, it is preferred to make the light flash gently or to repeat it.

The display device 1 performs a "meeting" operation at the initial setting. Specifically, the CPU 110 displays a video of several seconds on the display surface 2a when the preliminary setting is completed. For example, as shown in Fig. 24, when the preliminary setting is completed, the LED 71 is blinked and the light is emitted from the light guide 6, and on the other hand, an image like a bubble diffusion is displayed on the display surface 2a. Fig. 24 is a schematic diagram showing the outline of the operation of the "meeting" of the display device. That is to say, when the connection with WiFi or Bluetooth is completed, the CPU 110 can also output a part of the display surface 2a or the LED 71.

Alternatively, when the upgrade of the software is completed, the CPU 110 may also output a part of the display surface 2a or the LED 71. That is to say, in the state in which the software is upgraded, the CPU 110 can also output a part of the display surface 2a or the LED 71 by the user in a state where the power of the display device 1 is not turned off.

When the reservation operation is performed, the display device 1 performs a "notification" operation until a predetermined time of the reservation operation. Specifically, the CPU 110 causes a part of the display surface 2a or the LED 71 to perform the same output as "Reaction (small)" or perform other lighting/blinking operations. In this way, the image will not be disturbed when notified. However, the CPU 110 can still display the text of the notification information on the display surface 2a, or output the notified information through the speaker 170 as a sound.
