DETAILED DESCRIPTION

[0057] As described in the background, the display device in the related art includes a display module, a filter and a lens array which are sequentially stacked, the display module can include a plurality of light emitting elements, the light emitted by each light emitting element of the display module can form light of different colors by passing through the filter, the light passing through the filter can propagate towards the lens array, and after being refracted by the lens array, the light can be emitted in different directions, so that a display image can be formed in multiple directions.

[0058] For example, the plurality of light emitting elements can include a plurality of first light emitting elements, a plurality of second light emitting elements and a plurality of third light emitting elements, the plurality of first light emitting elements, the plurality of second light emitting elements and the plurality of third light emitting elements can form a plurality of pixel units, each pixel unit can include one first light emitting element, one second light emitting element and one third light emitting element, so that the pixel unit can integrate and combine the light from the first light emitting element, the second light emitting element and the third light emitting element to form a light beam of different colors.

[0059] The filter can include a red filter part, a green filter part and a blue filter part arranged in the same layer, wherein the red filter part can receive light from the first light emitting element to make the first light emitting element form a red light emitting element, the first light emitting element can emit red light by passing through the red filter part. The green filter part can receive light from the second light emitting element to make the second light emitting element form a green light emitting element, the second light emitting element can emit green light by passing through the green filter part. The blue filter part can receive light from the third light emitting element to make the third light emitting element form a blue light emitting element, the third light emitting element can emit blue light by passing through the blue filter part.

[0060] It is easy to understand that the red filter part, the green filter part and the blue filter part arranged in the same layer need to accurately correspond to the plurality of light emitting elements, when the position accuracy between the filter and the display module is low, the red filter part, the green filter part and the blue filter part are offset from the corresponding light emitting elements, so that the cooperation of the plurality of light emitting elements and the filter is prone to deviation, and the display effect of the display device is poor. Moreover, due to the different refractive indexes of the lens array to the red light, the green light and the blue light, the display device is prone to form a view point deviation, and further form color crosstalk between different view points, and the display effect of the display device is poor.

[0061] Therefore, the display device in the embodiments of the present application includes a display module and a lens array, wherein the display module includes a plurality of light emitting elements, and the lens array includes a plurality of filter lenses. When the display device is in a working state, the plurality of light emitting elements emit light towards the plurality of filter lenses, and the filter lenses filter the light to change the color of the light. The filter lenses deflect the light to change the propagation direction of the light, so that the light emitted by the display module can pass through the lens array.

[0062] Compared with the display device in the related art, the display device in the embodiments of the present application can combine the filter and the lens array, so that each part of the filter does not need to accurately correspond to each light emitting element of the display device, and the refractive index deviation of the lens array to light of different wave bands can be eliminated, the possibility of forming a view point deviation of the display device is reduced, the possibility of forming color crosstalk between different view points is reduced, and the display effect of the display device is improved.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0070] Referring to Figures 1-4 The display device of the embodiments of the present application can be set as a naked eye 3D display device. The display device includes a display module 100 and a lens array 200. The display module 100 can include a plurality of light emitting elements 120, and the lens array 200 can include a plurality of light filtering lenses 210, which can be arranged on the light emitting side of the plurality of light emitting elements 120.

[0071] When the display device is in a working state, the plurality of light emitting elements 120 emit light towards the plurality of lens arrays 200, and the light filtering lenses 210 filter the light to change the color of the light. The light filtering lenses 210 deflect the light to change the propagation direction of the light, so that the light emitted by the display module 100 can pass through the lens array 200.

[0072] Referring toFigures 1-4 In some possible embodiments, the display module 100 can include a substrate 110. A plurality of light emitting elements 120 can be disposed on the substrate 110, and the plurality of light emitting elements 120 can be arranged in multiple rows and multiple columns. The light emitting elements 120 can emit white light rays in a direction away from the substrate 110, so that the white light rays can propagate toward the light filtering lens 210.

[0073] For example, the display module 100 can further include a liquid crystal layer 130 disposed on a light emitting side of the light emitting elements 120. The liquid crystal layer 130 can include a plurality of liquid crystal units corresponding to the plurality of light emitting elements 120, and the liquid crystal units can be used to deflect and adjust the white light rays from the light emitting elements 120.

[0074] The light filtering lens 210 can be disposed on a side of the liquid crystal layer 130 away from the light emitting elements 120. The light filtering lens 210 covers at least one liquid crystal unit, and a surface of the light filtering lens 210 away from the liquid crystal layer 130 is protrudingly disposed, so that the light filtering lens 210 can receive the white light rays from the liquid crystal unit.

[0075] Referring to Figure 1 and Figure 3 In some possible embodiments, the light filtering lens 210 can be disposed as a light filtering column lens, and at least part of the light filtering column lens can be arranged in the same row. The extension direction of the light filtering column lens can be parallel to the column direction of the light emitting elements 120, and the row direction of the light filtering column lens can be parallel to the row direction of the light emitting elements 120.

[0076] In the column direction of the light filtering column lens, the light filtering column lens can receive light rays from a plurality of light emitting elements 120. In the row direction of the light filtering column lens, the light filtering column lens can receive light rays from a plurality of light emitting elements 120. The light filtering column lens can receive light rays from a plurality of light emitting elements 120, so that it is not necessary to be disposed one-to-one corresponding to the light emitting elements 120.

[0077] It can be easily understood that, in the related art display device, the red light filtering part 212, the green light filtering part 212, and the blue light filtering part 212 arranged in the same layer need to accurately correspond to the plurality of light emitting elements 120. When the position accuracy between the light filtering sheet and the display module 100 is low, the red light filtering part 212, the green light filtering part 212, and the blue light filtering part 212 are offset from the corresponding light emitting elements 120, so that the cooperation between the plurality of light emitting elements 120 and the light filtering sheet is prone to deviation, and the display effect of the display device is poor.

[0078] Since the light emitted by the light emitting elements 120 corresponding to the filter column lens is white light, the filter column lens does not need to be accurately formed corresponding to the light emitting elements 120 in the forming process, and the forming precision of the filter column lens can be appropriately reduced, reducing the possibility of deviation of the plurality of light emitting elements 120 and the filter column lens, thereby making the forming process of the filter column lens more convenient.

[0079] For example, the filter column lens in the same row can include a plurality of first filter column lenses 210a, a plurality of second filter column lenses 210b, and a plurality of third filter column lenses 210c. The first filter column lenses 210a, the second filter column lenses 210b, and the third filter column lenses 210c can be arranged alternately in sequence.

[0080] The first filter column lenses 210a, the second filter column lenses 210b, and the third filter column lenses 210c are arranged alternately in sequence. The plurality of light emitting elements 120 can emit first light through the first filter column lenses 210a, and the first light is set as red light. The plurality of light emitting elements 120 can emit second light through the second filter column lenses 210b, and the second light is set as green light. The plurality of light emitting elements 120 can emit third light through the third filter column lenses 210c, and the third light is set as blue light, thereby forming a display image through the first light, the second light, and the third light.

[0081] The first filter column lens 210a can be set as a red filter column lens. The red filter column lens can receive white light from the plurality of light emitting elements 120, and is used to filter and refract the white light from the corresponding plurality of light emitting elements 120, thereby forming refracted red light.

[0082] The second filter column lens 210b can be set as a green filter column lens. The green filter column lens can receive white light from the plurality of light emitting elements 120, and is used to filter and refract the white light from the corresponding plurality of light emitting elements 120, thereby forming refracted green light.

[0083] The third filter column lens 210c can be set as a blue filter column lens. The blue filter column lens can receive white light from the plurality of light emitting elements 120, and is used to filter and refract the white light from the corresponding plurality of light emitting elements 120, thereby forming refracted blue light.

[0084] For example, in the filter column lens arranged in the same row, a partition 220 can be arranged between two adjacent filter column lenses. The partition 220 can be used to block light to some extent, reducing the possibility of mutual interference of light emitted by adjacent filter column lenses, and improving the display effect of the display device.

[0085] Referring to Figure 5and Figure 7 In some possible embodiments, the plurality of light filtering lenses 210 can be arranged in multiple rows and multiple columns, so that the light emitted by the light emitting elements 120 can pass through the refraction and light filtering of the light filtering lenses 210.

[0086] The column direction of the light filtering lenses 210 can be parallel to the column direction of the light emitting elements 120, and the row direction of the light filtering lenses 210 can be parallel to the row direction of the light emitting elements 120. The light filtering lenses 210 can receive light from a plurality of rows and a plurality of columns of the light emitting elements 120.

[0087] For example, in the column direction of the light filtering lenses 210, the light filtering lenses 210 can receive light from a plurality of light emitting elements 120. In the row direction of the light filtering lenses 210, the light filtering lenses 210 can receive light from a plurality of light emitting elements 120. The light filtering lenses 210 can receive light from a plurality of light emitting elements 120, so that the light filtering lenses 210 do not need to be arranged one-to-one with the light emitting elements 120.

[0088] For example, the light filtering lenses 210 can be arranged as light filtering spherical lenses. The plurality of light filtering spherical lenses can include a plurality of first light filtering spherical lenses 210d, a plurality of second light filtering spherical lenses 210e, and a plurality of third light filtering spherical lenses 210f. The first light filtering spherical lenses 210d, the second light filtering spherical lenses 210e, and the third light filtering spherical lenses 210f can be arranged alternately.

[0089] The first light filtering spherical lenses 210d, the second light filtering spherical lenses 210e, and the third light filtering spherical lenses 210f are arranged alternately. A plurality of light emitting elements 120 can emit first light through the first light filtering spherical lenses 210d, and the first light is red light. A plurality of light emitting elements 120 can emit second light through the second light filtering spherical lenses 210e, and the second light is green light. A plurality of light emitting elements 120 can emit third light through the third light filtering spherical lenses 210f, and the third light is blue light, so that a display image can be formed by the first light, the second light, and the third light.

[0090] The first light filtering spherical lenses 210d can be arranged as red light filtering spherical lenses. The red light filtering spherical lenses can receive white light from a plurality of light emitting elements 120, and are used to filter and refract the white light from the corresponding plurality of light emitting elements 120, so as to form refracted red light.

[0091] The second light filtering spherical lenses 210e can be arranged as green light filtering spherical lenses. The green light filtering spherical lenses can receive white light from a plurality of light emitting elements 120, and are used to filter and refract the white light from the corresponding plurality of light emitting elements 120, so as to form refracted green light.

[0092] The third filter spherical lens 210f can be configured as a blue filter spherical lens. The blue filter spherical lens can receive white light from a plurality of light emitting elements 120, and is configured to filter and refract the white light from the corresponding plurality of light emitting elements 120, thereby forming refracted blue light.

[0093] For example, in the filter spherical lenses arranged in the same row, a partition 220 can be arranged between two adjacent filter spherical lenses. The partition 220 can be configured to block light to some extent, reduce the possibility of mutual interference of light emitted by the two adjacent filter spherical lenses, and improve the display effect of the display device.

[0094] Referring to Figure 2 and Figure 6 In some possible embodiments, the filter lens 210 can be configured as an integrated filter lens 210.

[0095] It is easy to understand that when the integrated filter lens 210 is formed, the dye can be mixed in the photoresist or other refractive material, so that the photoresist mixed with the dye forms the integrated filter lens 210, so that the refractive index of the integrated filter lens 210 is more uniform, and the refraction effect of the integrated filter lens 210 on the light is improved.

[0096] It should be noted that when the display device is in a working state, the plurality of light emitting elements 120 emit light towards the plurality of integrated filter lenses 210. Among them, the plurality of light emitting elements 120 can emit white light towards the same integrated filter lens 210, and the integrated filter lens 210 can filter the light to change the color of the light, and deflect the light to change the propagation direction of the light, thereby realizing the filtering and refraction of the light by the integrated filter lens 210.

[0097] It is easy to understand that the plurality of integrated filter lenses 210 can include a plurality of first integrated filter lenses 210, a plurality of second integrated filter lenses 210, and a plurality of integrated filter lenses 210. The integrated filter lens 210 can be configured as a filter cylindrical lens, or the integrated filter lens 210 can be configured as a filter spherical lens, which will not be described herein.

[0098] In some possible embodiments, the filter lens 210 includes a refractive portion 211 and a filter portion 212. At least part of the refractive portion 211 and at least part of the filter portion 212 are arranged along the incident direction of the light, so that the light can pass through at least part of the refractive portion 211 and at least part of the filter portion 212, so that the light can be deflected by the refractive portion 211 and filtered by the filter portion 212.

[0099] The refracting portion 211 can be arranged on the side of the light filtering portion 212 close to the light emitting element 120, and the light emitted by the light emitting element 120 can pass through the refracting portion 211 and the light filtering portion 212 in sequence. The refracting portion 211 can be arranged on the side of the light filtering portion 212 away from the light emitting element 120, and the light emitted by the light emitting element 120 can pass through the light filtering portion 212 and the refracting portion 211 in sequence.

[0100] When the light passes through the light filtering lens 210, the light can pass through the refracting portion 211, and the refracting portion 211 can deflect the light to change the propagation direction of the light. The light can also pass through the light filtering portion 212, and the light filtering portion 212 can filter the light to change the color of the light, so that the light filtering and refraction of the light can be achieved by the matched refracting portion 211 and light filtering portion 212.

[0101] For example, in the light filtering lens 210, the refractive index of the refracting portion 211 and the refractive index of the light filtering portion 212 can be the same. Alternatively, the refractive index of the refracting portion 211 and the refractive index of the light filtering portion 212 can be different.

[0102] Referring to Figure 2 and Figure 8 In some possible embodiments, the light filtering portion 212 can be arranged on the side of the refracting portion 211 facing the light emitting element 120. The light filtering portion 212 can be arranged as a planar light filtering portion 212, and the surface of the planar light filtering portion 212 facing the refracting portion 211 can be arranged parallel to the display module 100.

[0103] When the light passes through the light filtering lens 210, the light can first pass through the light filtering portion 212 of the light filtering lens 210, and the light filtering portion 212 can filter the light to change the color of the light. In addition, the light passing through the light filtering portion 212 can also pass through the refracting portion 211, and the refracting portion 211 can deflect the light to change the propagation direction of the light.

[0104] Referring to Figure 8 , the surface of the refracting portion 211 facing the display module 100 can completely adhere to the surface of the light filtering portion 212 away from the display module 100.

[0105] The contact area of the refracting portion 211 and the light filtering portion 212 can be equal to the area of the light filtering portion 212 away from the display module 100, or the contact area of the refracting portion 211 and the light filtering portion 212 can be smaller than the area of the light filtering portion 212 away from the display module 100, so that the light entering the refracting portion 211 can pass through the light filtering portion 212, thereby improving the light filtering effect of the light filtering portion 212 and reducing the possibility that the light does not pass through the light filtering portion 212 and enters the refracting portion 211.

[0106] Alternatively, the surface of the refractive portion 211 facing the display module 100 can be partially attached to the surface of the light filtering portion 212 facing away from the display module 100. The surface of the refractive portion 211 facing the display module 100 can also be partially not attached to the light filtering portion 212.

[0107] For example, the partial partition 220 can be arranged on the surface of the light filtering portion 212 facing away from the display module 100, so that the partial partition 220 can separate and block part of the light, so that the light not passing through the light filtering portion 212 can be blocked by the partial partition 220.

[0108] Alternatively, referring to Figure 2 and Figure 9 , the light filtering portion 212 can be arranged on the side of the refractive portion 211 facing away from the light emitting element 120. The light filtering portion 212 can be arranged as an arc-shaped light filtering portion 212, and the surface of the arc-shaped light filtering portion 212 facing away from the refractive portion 211 is arranged in parallel with the surface of the refractive portion 211 facing away from the light emitting element 120.

[0109] When the light passes through the light filtering lens 210, the light can pass through the refractive portion 211 of the light filtering lens 210, and the refractive portion 211 can deflect the light to change the propagation direction of the light. In addition, the light passing through the refractive portion 211 can also pass through the light filtering portion 212, and the light filtering portion 212 can filter the light to change the color of the light.

[0110] For example, referring to Figure 2 , Figure 10 and Figure 11 , the refractive portion 211 can be provided with a groove. The groove can face the light emitting element 120, and the groove can accommodate the light filtering portion 212.

[0111] When forming the light filtering lens 210, the groove can be formed in the refractive portion 211 first, and then the light filtering portion 212 can be formed in the groove by processes such as inkjet printing, photolithography and transfer, so as to realize the forming process of the light filtering lens 210. The groove can play a certain positioning and accommodating role, so that the preparation process of the light filtering lens 210 is more convenient.

[0112] It should be noted that, referring to Figure 10 , the contact area of the refractive portion 211 and the light filtering portion 212 can be equal to the area of the refractive portion 211 on the side of the light filtering portion 212 facing away from the display module 100.

[0113] The area of the groove bottom surface of the refractive portion 211 can be equal to the area of the refractive portion 211 in the plane where the groove bottom surface is located. The side wall thickness of the groove is small, so as to increase the contact area of the refractive portion 211 and the light filtering portion 212, and increase the height of the light filtering portion 212, improve the light filtering effect of the light filtering portion 212, and reduce the possibility that the light does not pass through the light filtering portion 212 and enters the refractive portion 211.

[0114] Alternatively, the area of the groove bottom surface of the refractive portion 211 can be smaller than the area of the refractive portion 211 in the plane of the groove bottom surface, and the side wall thickness of the groove can be large, thereby improving the stability of the refractive portion 211 and reducing the possibility of breakage of the refractive portion 211.

[0115] For example, referring to Figure 12 and Figure 13 , the display device can further include a light-transmitting film layer 140. The light-transmitting film layer 140 can be disposed on the side of the light-emitting element 120 facing the lens array 200, and the light-transmitting film layer 140 can be formed with accommodation grooves 150, and the number of the accommodation grooves 150 can be set to be multiple.

[0116] The light-filtering lens 210 can be disposed protruding towards the light-emitting element 120. Referring to Figure 9 , the light-filtering lens 210 can be disposed in the accommodation groove 150, and the surface of the light-filtering lens 210 facing away from the light-emitting element 120 can be disposed parallel to the substrate 110.

[0117] Referring to Figure 10 , the light-filtering lens 210 can be partially disposed in the accommodation groove 150, and the surface of the light-filtering lens 210 facing away from the light-emitting element 120 can protrude from the surface of the substrate 110.

[0118] The light-filtering lens 210 can be made of a transparent material such as photoresist, so that the white light from the liquid crystal cell can be refracted and filtered by the light-filtering lens 210.

[0119] It is easy to understand that the light-filtering lens 210 and the light-transmitting film layer 140 can be integrally disposed.

[0120] For example, the preparation process of the light-filtering lens 210 and the light-transmitting film layer 140 can be realized by photoetching or transfer printing, so that the forming process of the light-filtering lens 210 and the light-transmitting film layer 140 is more convenient, and the stability of the connection between the light-filtering lens 210 and the light-transmitting film layer 140 can be improved, and the possibility of the light-filtering lens 210 being separated from the light-transmitting film layer 140 can be reduced.

[0121] Alternatively, the light filtering lens 210 can be connected with the light transmission film layer 140 by bonding or the like, so that the light filtering lens 210 and the light transmission film layer 140 are formed respectively, thereby making the forming process of the light filtering lens 210 more convenient, and the separately formed light filtering lens 210 can be reused in other display devices of other structures, so as to improve the application range of the light filtering lens 210. In summary, the display device in the embodiments of the present application includes the display module 100 and the lens array 200, wherein the display module 100 includes a plurality of light emitting elements 120, and the lens array 200 includes a plurality of light filtering lenses 210. When the display device is in a working state, the plurality of light emitting elements 120 emit light towards the plurality of light filtering lenses 210, and the light filtering lenses 210 filter the light to change the color of the light. The light filtering lenses 210 deflect the light to change the propagation direction of the light, so that the light emitted by the display module 100 can pass through the lens array 200.

[0122] Compared with the display device in the related art, the display device in the embodiments of the present application can combine the light filter and the lens array 200, so that each part of the light filter does not need to be accurately corresponded to each light emitting element 120 of the display device, and the refractive index deviation of the lens array 200 to light of different wave bands can be eliminated, the possibility of forming a view point deviation of the display device can be reduced, the possibility of forming color crosstalk between different view points can be reduced, and the display effect of the display device can be improved.
