[0007] Problems to be Solved by the Invention

[0008] However, in the case of the existing display switching device described in Patent Document 1, light 103 emitted from a light source 102 is incident on 7 pixels in the vertical direction via the biconvex lens 101. In each of the 7 pixels in the vertical direction, there is a problem that it is difficult to ensure the uniformity of the display of the pixel area (△ and ○). In particular, in the pixels arranged at the upper end and the lower end of the 7 pixels in the vertical direction, that is, the pixels where the incident angle of the light 103 relative to the biconvex lens 101 is a wide angle, the intensity of the light in the front direction is reduced, so there is also a problem that the uniformity of the display of the pixel area (△ and ○) is particularly deteriorated. Even if the light source 102 is moved in the direction C in the figure, this problem cannot be improved.

[0009] exist Fig.37 In the case of the conventional display switching device 200 shown in the figure, similarly, light emitted from a first light source 201A is incident on the first pixel region 205A, 205A' of the display unit 204 via the lens array 203, and light emitted from a second light source 201B is incident on the second pixel region 205B of the display unit 204 via the lens array 203, so there is a problem that it is difficult to ensure the uniformity of the display of the first pixel region 205A, 205A' and the second pixel region 205B. In particular, in the case of the first pixel region 205A', the incident angle of the light from the first light source 201A with respect to the lens array 203 becomes wide, so the intensity of the light component HA' after passing through the first pixel region 205A' in the front direction is lower than the light component HA after passing through the first pixel region 205A and the light component HB after passing through the second pixel region 205B, so there is also a problem that the uniformity of the display of the first pixel region 205A' is particularly deteriorated. Summary of the invention

[0010] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a display switching device that improves the uniformity of display in a pixel region.

[0011] In order to solve the above-mentioned problem, an image forming device of one embodiment of the present invention switches the displayed image by switching the irradiation of light from multiple light source groups including multiple light sources for each light source group, wherein the device comprises: a lens array in which multiple lenses are arranged; a display unit including multiple pixel areas, wherein the multiple pixel areas are configured to include areas through which light emitted from the multiple light source groups passes and is focused by each of the lenses of the lens array, and the transmittance of each of the pixel areas is set corresponding to a specified static pattern, and light from the multiple light sources included in the specified light source group is focused on at least one of the pixel areas through different lenses.

[0012] According to the above structure, since the lights from the plurality of light sources included in the predetermined light source group are focused on at least one pixel region by different lenses, a display switching device that improves the uniformity of display in the pixel region can be realized. Therefore, the display switching device can be made larger and thinner.

[0013] In addition, in the display switching device of the above-mentioned aspect, the light source group includes at least the first light source group and the second light source group, and the multiple pixel areas include at least the first pixel area group and the second pixel area group, and the light emitted from the 1-1 light source included in the first light source group is focused by the first lens of the lens array and then irradiated to the 1-1 pixel area included in the first pixel area group, and the light emitted from the 1-2 light sources included in the first light source group is focused by the second lens of the lens array and then irradiated to the 1-1 pixel area included in the first pixel area group, the light emitted from the 2-1 light source included in the second light source group is focused by the first lens and then irradiated to the 2-1 pixel area included in the second pixel area group, and the light emitted from the 2-2 light source included in the second light source group is focused by the second lens and then irradiated to the 2-1 pixel area included in the second pixel area group.

[0017] Furthermore, in the display switching device according to the above aspect, the first lens and the second lens are adjacent to each other.

[0018] According to the above configuration, a display switching device can be realized that improves the display uniformity of the 1-1 pixel region and the 2-1 pixel region, thereby achieving a larger and thinner display switching device.

[0019] In the display switching device according to the above aspect, the lens array is a structure in which the lenses are arranged in a two-dimensional matrix, and light focused by four adjacent lenses is irradiated onto at least one of the pixel regions.

[0020] According to the above configuration, it is possible to realize a display switching device that improves the uniformity of display in the pixel region by using a plurality of relatively compact optical systems.

[0021] Furthermore, in the display switching device according to the above aspect, an area of ​​the lens array is larger than an area of ​​a region where the light source is arranged.

[0025] In addition, the display switching device according to the above aspect further includes a light shielding unit that shields a portion of an emission angle range of the light emitted from the light source.

[0026] According to the above configuration, since wide-angle light can be shielded by the light shielding portion, a display switching device can be realized in which image quality degradation due to aberration is suppressed.

[0027] Furthermore, in the display switching device according to the above aspect, the intensities of the plurality of light sources included in the predetermined light source group are different from each other.

[0028] According to the above configuration, it is possible to realize a display switching device that further improves the uniformity of display in the pixel region.

[0029] Furthermore, in the display switching device according to the above aspect, the plurality of light sources included in the predetermined light source group emit light of different colors from each other.

[0030] According to the above configuration, since the pixel region can be expressed in a plurality of colors, it is possible to realize a display switching device capable of creating a new appearance.

[0031] Furthermore, in the display switching device according to the above aspect, the light irradiated to the lens is collimated light.

[0032] According to the above configuration, it is possible to suppress the degradation of image quality due to aberration and realize a display switching device that further improves the display uniformity of the pixel region.

[0033] Furthermore, the display switching system according to the above aspect includes a plurality of the display switching devices, and the display units of the display switching devices are arranged adjacent to each other.

[0034] According to the above configuration, it is possible to realize a display switching system capable of performing large display and display in any shape.

[0035] Furthermore, the switch according to the above aspect includes the display switching device, and detects an operation of the display switching device by a user.

[0093] based on Figures 1 to 35 Hereinafter, for convenience of description, the same reference numerals are given to structures having the same functions as those described in a specific embodiment, and the description thereof may be omitted.

[0094] (Implementation Method 1)

[0095] Figure 1 1 is a diagram showing a schematic structure of a display switching device 10 according to Embodiment 1. Figure 1 As shown, the display switching device 10 includes, in order from bottom to top in the figure: a substrate 9, a plurality of light sources 1A, 1B, 2A, a lens array 3 including a plurality of micro lenses L0 to L7, a display unit 4 including a plurality of pixel regions 4A, 4A' for displaying a first pattern and a plurality of pixel regions 4B for displaying a second pattern, and a light diffusion component 5. The lens array 3, the display unit 4, and the light diffusion component 5 are supported by a housing 6, and the housing 6 is installed on the substrate 9 on which the plurality of light sources 1A, 1B, 2A are installed, thereby forming the display switching device 10. The display switching device 10 may also include a protective layer for preventing damage above the light diffusion component 5.

[0096] At least one of the housing 6 and the substrate 9 is preferably formed of a light absorbing material. In the case of adopting such a structure, it is possible to prevent the light reflected by the lens array 3 or the display unit 4 from passing through the lens array 3 and the display unit 4 again and being visually recognized by the user. In addition, when the plurality of light sources 1A, 1B, and 2A are not emitting light, it is possible to prevent the image of the pixel regions 4A, 4A', and 4B of the display unit 4 from appearing faint due to the internal reflection of the disturbance light.

[0097] In the present embodiment, the case where the display switching device 10 has LEDs (for example, RGBLEDs) as point light sources as light sources 1A, 1B, and 2A is described as an example, but the present invention is not limited to this. As the light sources 1A, 1B, and 2A, a rod-shaped light guide rod or a light guide body that emits light only in a specified area described later may also be used. Furthermore, a laser may also be used as a light source. In addition, an RGBLED is a light source that packages an LED that emits red light, an LED that emits green light, and an LED that emits blue light as one light source, and can control the brightness of each color LED separately. In addition, in the present embodiment, the case where the display switching device 10 has four light sources belonging to the first light source group including the light source 1A and the light source 2A and four light sources belonging to the second light source group including the light source 1B is described as an example, but the present invention is not limited to this. The number of light sources, the distance between the light sources, the size of the light sources, etc. can be appropriately set as needed.

[0098] In the present embodiment, the lens pitch LP of the plurality of microlenses L0 to L7 of the lens array 3 is 0.25 mm, the thickest portion of the lens array 3 including the plurality of microlenses L0 to L7 is 0.5 mm, the refractive index of the lens array 3 is 1.5, and the shortest distance LD between the light sources 1A, 1B, 2A and the microlenses L0 to L7 is 30 mm, but is not limited thereto. The number of microlenses of the lens array 3, the lens pitch LP of the microlenses, the thickness of the lens array 3, the refractive index of the lens array 3, the shortest distance LD between the light source and the microlenses, etc. can be appropriately set as needed.

[0099] Figure 2 It is a diagram showing a schematic configuration of the display unit 4 included in the display switching device 10 .

[0100] Figure 3 1 and 2 are diagrams showing a switching display example of the display unit 4 included in the display switching device 10 .

[0101] like Figure 2 As shown, predetermined patterns such as the first pattern and the second pattern are displayed on the display unit 4 while switching. Figure 2 The display unit 4 includes an enlarged view of the portion A of the display unit 4 and an enlarged view of the portion B of the enlarged view of the portion A of the display unit 4. The display unit 4 is composed of Figure 3 The first pattern P1 (in the example, the hiragana character “き”) shown in FIG. Figure 3 The second pattern P2 shown (pattern "△" in the example) is composed of a plurality of pixel areas 4B and a portion 4S other than the pixel areas 4A, 4A', and 4B. The plurality of pixel areas 4A, 4A', and 4B are openings for displaying the first pattern P1 or the second pattern P2 through light from the light sources 1A, 1B, and 2A. The portion 4S other than the pixel areas 4A, 4A', and 4B is a portion that acts as a mask to make the transmittance of the light from the light sources 1A, 1B, and 2A lower than that of the pixel areas 4A, 4A', and 4B. The portion 4S other than the pixel areas 4A, 4A', and 4B is preferably formed of a black matrix with high light-shielding properties, etc., but as long as it is a material that can make the transmittance of the light from the light sources 1A, 1B, and 2A lower than that of the pixel areas 4A, 4A', and 4B, there is no particular limitation. The display unit 4 can also be provided on a substrate that transmits visible light. In the present embodiment, an example is given in which the display unit 4 is formed by a layer such as a black matrix, but it is not limited thereto. For example, the display unit 4 may be formed of two layers. In this case, the first layer arranged as a lower layer close to the light sources 1A, 1B, 2A may be composed of a layer in which a plurality of openings for passing light and a transmissive region having a predetermined transmittance are formed in the pixel regions 4A, 4A', 4B included in the second layer as an upper layer. The second layer arranged as an upper layer away from the light sources 1A, 1B, 2A includes the pixel regions 4A, 4A', 4B.

[0102] Figure 4 This is a diagram showing a correspondence relationship between a display unit, a lens array, and a light source that can be included in the display switching device of the first embodiment.

[0103] As described above, in this embodiment, the plurality of pixel regions 4A and 4A′ are used to display Figure 3 The first pattern P1 shown is displayed by a plurality of pixel regions 4B. Figure 3 The second pattern P2 shown in FIG. 1 is described as an example, but is not limited to this. Figure 4 As shown, in addition to the light sources 1A and 2A belonging to the first light source group and the light source 1B belonging to the second light source group, the light source 1C belonging to the third light source group and the light source 1D belonging to the fourth light source group are also included. Figure 3 In addition to the first pattern P1 and the second pattern P2 shown, a third pattern P3 and a fourth pattern P4 may be included to switch the display.

[0104] Figure 5 It is used to illustrate Figure 1 FIG. 2 is a diagram showing the optical effect of the display switching device 10 according to the first embodiment.

[0105] The display switching device 10 switches a display image by switching, for each light source group, irradiation of light from a first light source group including light sources 1A and 2A and irradiation of light from a second light source group including a plurality of light sources such as light source 1B.

[0106] In the display switching device 10, light from the light source 1A belonging to the first light source group is focused by the microlens L1 of the lens array 3, passes through the pixel area 4A (first pixel area) of the display unit 4, and is focused by the microlens L3 of the lens array 3, passes through the pixel area 4A' (first pixel area) of the display unit 4. In addition, light from the light source 2A belonging to the first light source group is focused by the microlens L2 of the lens array 3, passes through the pixel area 4A (first pixel area) of the display unit 4, and is focused by the microlens L4 of the lens array 3, passes through the pixel area 4A' (first pixel area) of the display unit 4. On the other hand, light from the light source 1B belonging to the second light source group is focused by the microlens L1 of the lens array 3, passes through the pixel area 4B (second pixel area) of the display unit 4.

[0107] As described above, in the display switching device 10, the light from the light source 1A and the light source 2A belonging to the first light source group are focused by different microlenses on the pixel area 4A (the first pixel area) and the pixel area 4A' and the first pixel area). Therefore, the uniformity of the display of the pixel area 4A (the first pixel area) and the pixel area 4A' (the first pixel area) is improved. Furthermore, the uniformity of the brightness between the pixel area 4A (the first pixel area) and the pixel area 4A' (the first pixel area) can also be improved. Therefore, the display switching device 10 can also be made larger and thinner.

[0108] like Figure 5As shown, in the case of the pixel area 4A, since the incident angle of the light from the light source 2A belonging to the first light source group to the microlens L2 of the lens array 3 becomes wide, the light component 2HA' after passing through the pixel area 4A has a reduced light intensity in the front direction, so the display uniformity deteriorates. Therefore, in the display switching device 10, the light from the light source 1A belonging to the first light source group is also focused on the pixel area 4A through the microlens L1 of the lens array 3. The light intensity in the front direction of the light component 1HA after passing through the pixel area 4A is relatively strong, which can improve the display uniformity of the pixel area 4A.

[0109] like Figure 5 As shown, in the case of the pixel area 4A', since the incident angle of the light from the light source 1A belonging to the first light source group to the microlens L3 of the lens array 3 becomes wide-angle, the light component 1HA' after passing through the pixel area 4A' has a reduced light intensity in the front direction, so the display uniformity deteriorates. Therefore, in the display switching device 10, the light from the light source 2A belonging to the first light source group is also focused on the pixel area 4A' through the microlens L4 of the lens array 3. The light intensity of the light component 2HA in the front direction after passing through the pixel area 4A' is relatively strong, which can improve the display uniformity of the pixel area 4A'.

[0110] Figure 6 It is a plan view showing the state of light passing through the display unit 4 of the display switching device 10 .

[0111] like Figure 6 As shown, the display unit 4 of the display switching device 10 performs display by illuminating the plurality of pixel regions 4A and 4A' with the plurality of light sources belonging to the first light source group, thereby improving the uniformity of display in the pixel regions 4A and 4A'.

[0112] Figure 7 4 is a diagram showing the uniformity of display on the display unit 4 when the light passing through the pixel regions 4A and 4A′ of the display switching device 10 is the light from one light source 1A. Figure 8 2A and 2B are diagrams showing the uniformity of display on the display unit 4 when the light passing through the pixel regions 4A and 4A' of the display switching device 10 is light from two light sources 1A and 2A. Figure 7 The circled X part and Figure 8 The circled Y portion shows that, as in the display switching device 10, when the light passing through the pixel regions 4A and 4A' is light from two light sources 1A and 2A, the display uniformity of the display unit 4, that is, the brightness uniformity of the display unit 4 is significantly improved.

[0113] In this embodiment, if Figure 5As shown, the light from the light source 1B belonging to the second light source group is focused on the pixel area 4B (the second pixel area) through the microlens L1 of the lens array 3. The intensity of the light in the front direction of the light component 1HB after passing through the pixel area 4B is relatively strong. This is not limited to this. As described later, as in the above-mentioned pixel area 4A (the first pixel area) and pixel area 4A' (the first pixel area), the light from the two light sources can also be focused through different microlenses of the lens array 3 in the pixel area 4B (the second pixel area).

[0114] Fig. 9 This is a diagram showing a schematic configuration of a modified example of the display switching device according to the first embodiment.

[0115] Fig. 9 The display switching device 10a shown further includes a collimator lens 8 between the light sources 1A, 1B, 2A and the lens array 3. The collimator lens 8 can collimate the light from the light sources 1A, 1B, 2A and make it incident on the micro lenses L0 to L7 of the lens array 3.

[0116] According to the above configuration, it is possible to suppress the degradation of image quality due to aberration and realize the display switching device 10a which further improves the uniformity of display in the pixel regions 4A and 4A′.

[0117] In this embodiment, the display switching device 10a is described as having a collimating lens 8, but is not limited to this. As long as the light from the light sources 1A, 1B, and 2A can be collimated, for example, a Fresnel lens, a collimating reflector, a Fresnel reflector, a light guide plate, etc. may be used instead of the collimating lens 8.
