Detailed Description
(first embodiment)
A first embodiment of a display device according to the present invention will be described with reference to the drawings. As shown in fig. 1, the display device 10 is a graphic table display device that displays a pointer table representing a vehicle speed by an image.
As shown in fig. 2, the display device 10 includes: a control unit 55 for controlling the entire display device 10, a liquid crystal panel 20, and a light source 30 for illuminating the liquid crystal panel 20. The control unit 55 includes: a microcomputer (microcomputer) 50 and a GDC (graphic display controller) 40 drawing an image on the liquid crystal panel 20 under the control of the microcomputer 50.
The GDC40 draws an image on the liquid crystal panel 20 under the control of the microcomputer 50. The liquid crystal panel 20 is a TFT (thin film transistor) type liquid crystal panel, and the transmittance is adjusted for each pixel under the control of the GDC 40.
The light source 30 is constituted by an LED (light emitting diode), and irradiates light, for example, white light, to the liquid crystal panel 20 under the control of the microcomputer 50.
The microcomputer 50 includes: a CPU51 that performs various controls according to a predetermined program; a ROM52 storing a program, an original image, and the like executed by the CPU51; and a RAM53 storing various data and having a work area required for processing operations of the CPU 51.
The ROM52 stores: for example, still image data representing a dial for an instrument; pointer image data representing a pointer rotated on the dial; fuzzy performance image data for performing a fuzzy performance on the pointer; and various thresholds TH1, TH2.
The microcomputer 50 obtains (acquires) vehicle information including a vehicle speed and the like from the outside, and displays an image including the vehicle information on the liquid crystal panel 20 via the GDC 40.
As shown in fig. 1, the microcomputer 50 displays the background image Ib as still image data via the GDC 40. In the background image Ib, the portions corresponding to the numerals and scales are displayed in white due to light transmission, and the background other than the portions is displayed in black due to light-tightness.
As shown in fig. 3, the microcomputer 50 displays the pointer image 80 as pointer image data via the GDC 40. The pointer image 80 is formed in a white bar shape, and rotates around the lower end of the pointer image 80 with respect to the numerical value and scale of the background image Ib. The pointer image 80 is set to the same light transmittance over the entire pointer image 80. The microcomputer 50 acquires vehicle information including the vehicle speed from the outside at predetermined intervals (for example, 1/60 second), and updates the position of the pointer image 80. Thereby, the pointer image 80 rotates according to the vehicle speed.
As shown in fig. 3, 4 and 5, the microcomputer 50 displays, as blurred show image data, blurred pointer images 60, 71, 72 in which the shake of the pointer image 80 appears, via the GDC 40.
As shown in fig. 3 and (c) in fig. 4, the blurred pointer image 60 is located in a direction away from the pointer image 80 and opposite to the rotation direction of the pointer image 80, and is formed to have a gradual white bar shape. The blurred pointer image 60 is displayed to visualize the afterimage of the pointer image 80 when the rotational speed of the pointer image 80 rotates at greater than or equal to the threshold TH2. For example, when the pointer image 80 rotates in the clockwise direction Cw, as shown in fig. 3, the blurred pointer image 60 is displayed at the position of the pointer image 80 in the counterclockwise direction Ucw. On the other hand, when the pointer image 80 is rotated in the counterclockwise direction Ucw, although not shown, the blurred pointer image 60 is displayed at the position of the pointer image 80 in the clockwise direction Cw. In order to visualize the movement locus of the pointer image 80, the blurring pointer image 60 is set by the control section 55 to a display position with respect to the pointer image 80 according to the speed and acceleration of the pointer image 80. Therefore, the processing load of the control unit 55 for displaying the blurring pointer image 60 is greater than that of the blurring pointer images 71, 72.
As shown in (c) of fig. 4, the blur pointer image 60 is set to be gradual in such a manner that the light transmittance decreases with the direction of rotation of the blur pointer image 60 from the center toward the outside, and the light transmittance decreases with the direction toward the radial inside orthogonal to the direction of rotation. The width of the rotation direction (left-right direction of fig. 4) of the blurring pointer image 60 is formed to become smaller as going to the radial inside (lower direction of fig. 4).
As shown in fig. 4 (a) and (b), the blurred pointer images 71 and 72 are frame-shaped around the periphery of the pointer image 80, and move with the rotation of the pointer image 80.
As shown in (a) of fig. 4, when the rotational speed of the pointer image 80 is greater than or equal to the threshold TH1 and the pointer image 80 rotates in the clockwise direction Cw, the blurred pointer image 71 is displayed. The blur pointer image 71 includes: a hollowed-out portion 71a formed in a region overlapping with the pointer image 80; a clockwise image portion 71b formed in the clockwise direction Cw with respect to the hollowed-out portion 71a; and a counterclockwise image portion 71c formed in the counterclockwise direction Ucw with respect to the hollowed-out portion 71 a.
As shown in fig. 5 (a), a pointer image 80 is displayed in the hollowed-out portion 71 a. The clockwise side image portion 71b and the counterclockwise side image portion 71c are formed as: the width W along the rotation direction of the pointer image 80 becomes shorter as it goes toward the rotation center side (lower side of fig. 5) of the pointer image 80. That is, the clockwise side image portion 71b and the counterclockwise side image portion 71c are formed in a fan shape. The width W of the counterclockwise image portion 71c is formed longer than the width W of the clockwise image portion 71 b. In other words, the area of the counterclockwise image portion 71c is larger than the area of the clockwise image portion 71 b. The brightness of the counterclockwise image portion 71c is set lower than the brightness of the pointer image 80, and higher than the brightness of the clockwise image portion 71 b. That is, the magnitude relation of the respective brightnesses is set as: "luminance of pointer image 80 > luminance of counterclockwise side image portion 71c > luminance of clockwise side image portion 71 b". By setting the respective brightnesses in this way, a blurred performance can be performed more naturally.
The luminance related to the comparison of the magnitude relation may be the average luminance of each region of the pointer image 80, the counterclockwise side image portion 71c, and the clockwise side image portion 71b, or may be the highest luminance of each region.
In addition, the brightness is increased by increasing the light transmittance of the liquid crystal panel 20 or by increasing the output of the light source 30.
As shown in (a) in fig. 4 and (b) in fig. 5, when the rotational speed of the pointer image 80 is greater than or equal to the threshold TH1 and the pointer image 80 rotates in the counterclockwise direction Ucw, the blurred pointer image 72 is displayed. The blur pointer image 72 includes: a hollowed-out portion 72a formed in a region overlapping with the pointer image 80; a clockwise image portion 72b formed in the clockwise direction Cw with respect to the hollowed portion 72a; and a counterclockwise image portion 72c formed in the counterclockwise direction Ucw with respect to the hollowed-out portion 72 a. As shown in fig. 5 (b), a pointer image 80 is displayed in the hollowed portion 72 a. The clockwise side image portion 72b and the counterclockwise side image portion 72c are formed as: the width W along the rotation direction of the pointer image 80 becomes shorter as it goes toward the rotation center side (lower side of fig. 5) of the pointer image 80. That is, the clockwise side image portion 72b and the counterclockwise side image portion 72c are formed in a fan shape. The width W of the counterclockwise image portion 72c is formed shorter than the width W of the clockwise image portion 72b. In other words, the area of the counterclockwise image portion 72c is smaller than the area of the clockwise image portion 72b. The brightness of the clockwise side image portion 72b is set lower than the brightness of the pointer image 80, and higher than the brightness of the counterclockwise side image portion 72c. That is, the magnitude relation of the respective brightnesses is set as: "luminance of pointer image 80 > luminance of clockwise side image portion 72b > luminance of counterclockwise side image portion 72 c". By setting the respective brightnesses in this way, a blurred performance can be performed more naturally.
Next, the pointer display processing by the microcomputer 50 will be described with reference to the flowchart of fig. 6. The pointer display processing is repeatedly executed.
First, the microcomputer 50 determines whether the rotational speed of the pointer image 80 is greater than or equal to a threshold TH1 (step S101). The threshold value TH1 is set to 20 to 30deg/sec, for example. When it is determined that the rotational speed of the pointer image 80 is less than the threshold TH1 (step S101; no), the microcomputer 50 sets the rotational speed of the pointer image 80 in the low speed region, displays only the pointer image 80 without displaying the blurred pointer images 60, 71, 72 (step S102), and ends the pointer display processing.
On the other hand, when determining that the rotational speed of the pointer image 80 is greater than or equal to the threshold TH1 (step S101; yes), the microcomputer 50 determines whether the rotational speed of the pointer image 80 is greater than or equal to the threshold TH2 (step S103). The threshold value TH2 is set to, for example, 40 to 50deg/sec. When determining that the rotational speed of the pointer image 80 is less than the threshold TH2 (step S103; no), the microcomputer 50 sets the rotational speed of the pointer image 80 in the medium speed region, and determines whether or not the rotational direction of the pointer image 80 is the clockwise direction Cw (step S104).
When determining that the rotation direction of the pointer image 80 is the clockwise direction Cw (step S104; yes), the microcomputer 50 displays the pointer image 80 and one of the blurred pointer images 71 (step S105), and ends the pointer display processing.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is not the clockwise direction Cw, that is, the counterclockwise direction Ucw (step S104; no), the pointer image 80 and one of the blurred pointer images 72 are displayed (step S106), and the pointer display process is ended.
With the blurred pointer images 71 and 72 in the steps S105 and S106, when the rotation speed of the pointer image 80 is in the medium speed region, a blurred rendering corresponding to the rotation direction of the pointer image 80 can be performed with a relatively light processing load.
On the other hand, when determining that the rotational speed of the pointer image 80 is equal to or higher than the threshold TH2 (step S103; yes), the microcomputer 50 sets the rotational speed of the pointer image 80 in the high speed region, and determines whether or not the rotational direction of the pointer image 80 is the clockwise direction Cw (step S107). When determining that the rotation direction of the pointer image 80 is the clockwise direction Cw (step S107; yes), the microcomputer 50 displays the pointer image 80 and the two blurred pointer images 60, 71 (step S108), and ends the pointer display processing. Here, since the two blurring pointer images 60, 71 are displayed, blurring performance is enhanced as compared with the above step S105. Therefore, even when the rotational speed of the pointer image 80 is high, a natural blurring performance can be performed.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is not the clockwise direction Cw, that is, the counterclockwise direction Ucw (step S107; no), the pointer image 80 and the two blurred pointer images 60, 72 are displayed (step S109), and the pointer display process is ended. Here, the two blur pointer images 60, 72 are displayed, and thus the blur performance is enhanced compared with the above-described step S106. Therefore, even when the rotational speed of the pointer image 80 is high, a natural blurring performance can be performed.
The above description of the pointer display processing ends.
Next, an operation when the pointer image 80 rotates in the clockwise direction Cw from the home position (home position) to the target position and stops at the target position will be described.
The rotational speed of the pointer image 80 gradually increases from the original position toward the target position. When the rotational speed of the pointer image 80 is less than the threshold TH1, the pointer image 80 is displayed without displaying the blurred pointer images 71, 72. Then, when the rotational speed of the pointer image 80 rises, the blurred pointer image 71 is displayed when the rotational speed of the pointer image 80 is greater than or equal to the threshold TH1 and less than the threshold TH2. The blurred pointer image 71 moves integrally with the pointer image 80.
Further, when the rotational speed of the pointer image 80 increases as the pointer image 80 moves toward the target position, and the rotational speed of the pointer image 80 is equal to or higher than the threshold TH2, the blurred pointer image 60 is displayed while maintaining the blurred pointer image 71. The display position of the blur pointer image 60 is set by the control section 55 according to the speed and acceleration of the pointer image 80.
Then, as the pointer image 80 approaches the target position, the rotation speed gradually decreases, and when the rotation speed of the pointer image 80 is smaller than the threshold TH2, the blurred pointer image 60 is eliminated while maintaining the blurred pointer image 71.
Further, when the rotational speed of the pointer image 80 decreases, the blurring of the pointer image 71 is eliminated when the rotational speed of the pointer image 80 is smaller than the threshold TH 1. Then, the pointer image 80 reaches the target position without blurring the pointer images 71, 60.
In addition, in the case where the pointer image 80 is rotated in the counterclockwise direction Ucw from the original position to the target position, the same actions as those described above are performed except that the blurred pointer image 72 is displayed instead of the blurred pointer image 71.
(Effect)
According to the first embodiment described above, the following effects are achieved.
(1) The display device 10 includes: a liquid crystal panel 20 as an example of a display section that displays an image including a pointer image 80 as an example of an instruction section; and a control unit 55 for controlling the liquid crystal panel 20 to move the pointer image 80 in the image. When the moving speed of the pointer image 80 is equal to or higher than the threshold TH1 and the rotation direction of the pointer image 80 is the clockwise direction Cw, the control unit 55 displays a blurred pointer image 71 as an example of a blurred image including a clockwise side image portion 71b which is an example of a traveling direction image portion located in the traveling direction of the pointer image 80. On the other hand, when the moving speed of the pointer image 80 is equal to or greater than the threshold TH1 and the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the control section 55 displays the blurred pointer image 72 having the counterclockwise side image portion 72c as an example of the traveling direction image portion located in the traveling direction of the pointer image 80.
According to this configuration, the clockwise side image portion 71b of the blur pointer image 71 or the counterclockwise side image portion 72c of the blur pointer image 72 is displayed in the traveling direction of the pointer image 80. This can compensate for the delay in the response of the liquid crystal panel 20. Further, compared with the conventional case where the blurred pointer image is displayed only in the track direction of the pointer image, the movement of the pointer image 80 can be smoothly displayed, and a more natural blurred performance can be realized.
(2) When the moving speed of the pointer image 80 is equal to or higher than the threshold TH1 and the rotation direction of the pointer image 80 is the clockwise direction Cw, the blur pointer image 71 includes a counterclockwise side image portion 71c as an example of a track direction image portion located in the track direction of the pointer image 80 in addition to the clockwise side image portion 71 b. The brightness of the clockwise side image portion 71b is set lower than the brightness of the counterclockwise side image portion 71c. On the other hand, in the case where the moving speed of the pointer image 80 is equal to or greater than the threshold TH1 and the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the blur pointer image 72 includes, in addition to the counterclockwise side image portion 72c, a clockwise side image portion 72b as an example of a track direction image portion located in the track direction of the pointer image 80. The brightness of the counterclockwise side image portion 72c is set lower than the brightness of the clockwise side image portion 72b.
According to this configuration, the brightness of the counterclockwise image portions 71c and 72c and the brightness of the clockwise image portions 71b and 72b are adjusted according to the rotation direction of the pointer image 80, whereby a more natural blurring performance can be performed.
(3) The hollowed portions 71a, 72a are formed on the blurring pointer images 71, 72, and the hollowed portions 71a, 72a hollowed out the region corresponding to the pointer image 80 so that the blurring pointer images 71, 72 do not overlap with the pointer image 80.
According to this configuration, the overlapping of the blurring pointer images 71, 72 and the pointer image 80 is suppressed, and thus, the increase in the brightness of the overlapping region when the blurring pointer images 71, 72 and the pointer image 80 are overlapped is suppressed, and further, the light emission of the overlapping region is suppressed to display.
(4) The control unit 55 displays the blurred pointer images 71 and 72 as an example of the first blurred pointer image when the moving speed of the pointer image 80 is equal to or higher than a threshold TH1 as an example of the first threshold, and displays the blurred pointer image 60 as an example of the second blurred pointer image at a position apart from the pointer image 80 in the trajectory direction of the pointer image 80 when the pointer image 80 is equal to or higher than a threshold TH2 as an example of the second threshold that is higher than the threshold TH 1.
In the case of performing a blur presentation by the blur pointer image 60, it is necessary to set the position of the blur pointer image 60 based on the speed and acceleration of the pointer image 80, and the processing load of the control unit 55 is greater than in the case of performing a blur presentation by the blur pointer images 71 and 72. According to the above configuration, in the case where the moving speed of the pointer image 80 is greater than or equal to the threshold TH1 and less than the threshold TH2, the blurring performance is not performed by blurring the pointer image 60. Therefore, the processing load of the control unit 55 can be reduced.
(second embodiment)
A second embodiment of a display device according to the present invention will be described with reference to the drawings. The following description will focus on differences from the first embodiment.
In the present embodiment, as shown in fig. 7, a blur pointer image 73 is displayed instead of the blur pointer images 71, 72 according to the first embodiment.
Like the blur pointer images 71, 72, the blur pointer image 73 includes a hollowed-out portion 73a, a clockwise side image portion 73b, and a counterclockwise side image portion 73c. The clockwise side image portion 73b and the counterclockwise side image portion 73c have the same width W, respectively. The balance of the brightness of the clockwise side image portion 73b and the counterclockwise side image portion 73c in the blur pointer image 73 is adjusted according to the rotation direction of the pointer image 80.
As shown in fig. 8, when the rotation direction of the pointer image 80 is the clockwise direction Cw, the luminance of the clockwise side image portion 73b displayed in the blur pointer image 73 is set to be lower than the luminance of the counterclockwise side image portion 73c.
On the other hand, in the case where the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the brightness of the counterclockwise-side image portion 73c displayed in the blur pointer image 73 is set to be lower than the brightness of the clockwise-side image portion 73b of the counterclockwise-use blur pointer image 73Ucw.
Next, a method of generating the blur pointer image 73 will be described.
The microcomputer 50 reads out the original blur image 173 shown in fig. 8 stored in the ROM 52. The original blurred image 173 includes: a hollowed-out portion 173a, a clockwise side image portion 173b, and a counterclockwise side image portion 173c. The brightness of the clockwise side image portion 173b and the counterclockwise side image portion 173c are set to initial values, respectively.
When the microcomputer 50 determines that the rotation direction of the pointer image 80 is the counterclockwise direction Ucw, the counterclockwise blur pointer image 73Ucw is generated as the blur pointer image 73 by setting the brightness of the counterclockwise side image portion 173c to be lower than the brightness of the clockwise side image portion 173 b.
On the other hand, when the microcomputer 50 determines that the rotation direction of the pointer image 80 is the clockwise direction Cw, the clockwise blur pointer image 73Cw is generated as the blur pointer image 73 by setting the brightness of the clockwise side image part 173b to be lower than the brightness of the counterclockwise side image part 173c.
The microcomputer 50 displays the generated blur pointer image 73 on the liquid crystal panel 20.
As described above, the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw can be generated from one original blur image 173.
(Effect)
According to the second embodiment described above, the following effects are achieved.
(1) The display device 10 includes: the ROM52 as an example of the storage unit stores one original blur image 173 obtained by combining the clockwise side image 173b and the counterclockwise side image 173c located in the counterclockwise direction Ucw with respect to the clockwise side image 173 b. The control unit 55 generates the clockwise blur pointer image 73Cw by setting the brightness of the clockwise side image portion 173b in the original blur image 173 to be lower than the counterclockwise side image portion 173c when the pointer image 80 is rotated in the clockwise direction Cw, and generates the counterclockwise blur pointer image 73Ucw by setting the brightness of the counterclockwise side image portion 173c in the original blur image 173 to be lower than the clockwise side image portion 173b when the pointer image 80 is rotated in the counterclockwise direction Ucw.
By adjusting only the brightness of the clockwise side image portion 173b and the brightness of the counterclockwise side image portion 173c in one original blur image 173, the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw can be generated. Therefore, it is not necessary to prepare two original blurred images, and the amount of image data stored in the ROM52 of the microcomputer 50 can be reduced.
Further, since both the clockwise side image portion 73b and the counterclockwise side image portion 73c are displayed, the boundary between the clockwise side image portion 73b and the counterclockwise side image portion 73c becomes inconspicuous, and the blurred pointer image 73 with less sense of incongruity can be displayed.
(third embodiment)
A third embodiment of a display device according to the present invention will be described with reference to the drawings. The following description will focus on differences from the second embodiment.
As shown in fig. 11, the blurring pointer image 74 of the present embodiment does not have a hollowed-out portion. Thus, the blurred pointer image 74 has a repetitive region G overlapping with the pointer image 80.
Fig. 9 (a) and 10 (a) are graphs showing the luminance of the pointer image 80 in the width direction of the pointer image 80, fig. 9 (b) and 10 (b) are graphs showing the luminance of the blurred pointer image 74 in the width direction of the pointer image 80, and fig. 9 (c) and 10 (c) are graphs showing the luminance obtained by adding the luminance of the pointer image 80 and the luminance of the blurred pointer image 74.
In the overlap region G where the blurred pointer image 74 and the pointer image 80 overlap, the luminance after addition shown in (c) in fig. 9 as a comparative example is higher than the luminance of the pointer image 80 before overlapping the blurred pointer image 74 shown in (a) in fig. 9. Therefore, in the comparative example, when the blurred pointer image 74 is superimposed on the pointer image 80, the brightness of the overlap area G is increased, and the overlap area G emits light to be displayed, so that a sense of incongruity is given to the viewer.
In this regard, in the present embodiment, when the blurred pointer image 74 and the pointer image 80 are displayed in an overlapping manner, the control unit 55 reduces the luminance of the pointer image 80 in the overlap region G as shown in fig. 10 (a), and reduces the luminance of the blurred pointer image 74 in the overlap region G as shown in fig. 10 (b). Thus, as shown in fig. 10 (c), the added luminance in the repetition area G is equal to the luminance of the pointer image 80 before the blurring pointer image 74 is superimposed as shown in fig. 9 (a). The equality includes a delta of + -3%. Accordingly, when the blurring pointer image 74 is superimposed on the pointer image 80, the repetitive region G is suppressed from emitting light and being displayed, and the sense of incongruity is suppressed from being brought to the viewer.
In addition, the ratio of the reduction ratio of the luminance of the blurred pointer image 74 in the repetitive region G and the ratio of the reduction ratio of the luminance of the pointer image 80 in the repetitive region G can be appropriately adjusted.
(Effect)
According to the third embodiment described above, the following effects are achieved.
(1) The blurred pointer image 74 is displayed overlapping the pointer image 80. The luminance of the blurred pointer image 74 in the repetition area G and the luminance of the pointer image 80 in the repetition area G are set so that the luminance of the repetition area G where the blurred pointer image 74 and the pointer image 80 overlap is equal to the luminance of the pointer image 80 before the overlapping of the blurred pointer image 74.
According to this structure, when the blurring pointer image 74 is superimposed on the pointer image 80, the repetitive region G is suppressed from emitting light and displayed.
The present invention is not limited to the above embodiments and drawings. Changes (including deletion of constituent elements) can be added as appropriate within the scope not changing the gist of the present invention. An example of the modification will be described below.
(modification)
In the above embodiments, the blurring pointer image 60 is displayed in the high-speed region, but the blurring pointer image 60 may be omitted.
In the second embodiment described above, the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw are generated from one original blur image 173. However, not limited to this, two original blur images corresponding to the clockwise blur pointer image 73Cw and the counterclockwise blur pointer image 73Ucw, respectively, may be stored.
In the above embodiments, the counterclockwise-side image portion 71c in the blurring-pointer image 71 may be omitted, and the clockwise-side image portion 72b in the blurring-pointer image 72 may be omitted. That is, the travel direction image portion may be displayed, or the trajectory direction image portion may be omitted.
In the above embodiments, the display device 10 displays the indicator indicating the vehicle speed by the image, but the indicator indicating the engine speed and the remaining fuel may be used without being limited to the vehicle speed. In addition, a plurality of pointer tables may be displayed in one image. Further, the present invention is not limited to the pointer table, and a display device may be used in which a pointer, which is an example of the instruction unit, is moved on the screen in accordance with a user operation. In this case, the same blurred image as the blurred pointer images 60, 71, 72, 73, 74 is displayed according to the moving speed of the pointer.
In each of the above embodiments, the control unit 55 may switch the presence or absence of the blur performance based on a detection result of a line-of-sight detection unit that detects a line-of-sight direction of a driver, not shown. The control unit 55 performs a blur presentation by displaying the blur pointer images 60, 71, 72, 73, 74 when the line of sight detection unit determines that the line of sight of the driver is directed toward the liquid crystal panel 20, and does not perform a blur presentation by not displaying the blur pointer images 60, 71, 72, 73, 74 when the line of sight detection unit determines that the line of sight of the driver is not directed toward the liquid crystal panel 20. This reduces the number of invalid blur presentations in a state where the driver does not visually confirm the liquid crystal panel 20, and reduces the processing load of the control unit 55.
In the above embodiment, the display unit is the liquid crystal panel 20, but not limited to the liquid crystal panel 20, and may be an organic EL display (OELD: organic light emitting display).
