The filter protection layer 40 is used to encapsulate and protect the color filter layer 30. The protective cover plate 50 is used as the outer surface of the display screen assembly 100 to protect the display screen assembly 100. The light-emitting layer 20 can emit light with the assistance of the auxiliary layer 10, such as the drive circuit 11. The light passes through the color filter layer 30, adjusts the chromaticity, and then passes through the filter protection layer 40 and the protective cover plate 50 to emit out of the display screen assembly 100 for display. In some embodiments, a first light-transmitting unit 21 is provided in the light-emitting layer 20 to improve the transmittance of light.

[0034] In some embodiments, the auxiliary layer 10 is not provided with a driving circuit 11 at a position opposite to the first light-transmitting unit 21 and / or the second light-transmitting unit 31. That is, by adjusting the driving circuit 11, the auxiliary layer 10 is allowed to transmit light at a position opposite to the first light-transmitting unit 21 and / or the second light-transmitting unit 31, thereby reducing the blocking of light by the driving circuit 11 and improving the transmittance of light.

[0035] See also Figure 1 , a third light-transmitting unit 12 may be provided in the auxiliary layer 10 to transmit light and improve the transmittance of light. In some embodiments, the material of the third light-transmitting unit 12 may be OC (Over Coating) glue. In some embodiments, the third light-transmitting unit 12 may be a negative photoresist insulating photosensitive glue, and of course, it may also be other materials. In some embodiments, external light may sequentially pass through the protective cover 50, the filter protection layer 40, the color filter layer 30, the light-emitting layer 20 and the third light-transmitting unit 12, and the third light-transmitting unit 12 may improve the transmittance of light.

[0036] See also Figure 2 , Figure 2 for Figure 1 Schematic diagram of the structure of the auxiliary layer 10 in other embodiments in the illustrated embodiment. The auxiliary layer 10 may include a substrate 13 and a driving circuit layer 14. The substrate 13 may be stacked with the driving circuit layer 14 and the light-emitting layer 20 in sequence. In some embodiments, the driving circuit layer 14 may be provided with the driving circuit 11 in the above-mentioned embodiment. Of course, other stacks that can cooperate with the driving circuit 11 may also be provided. The stack may be one or more of a plurality of single stacks such as a planar layer, an interlayer dielectric layer, a gate insulating layer, a buffer layer and an insulating layer. Of course, the stack may not be limited to the embodiments listed here, but may also include other single stacks.

[0037] In some embodiments, the driving circuit layer 14 may be provided with a light-transmitting hole 141 for accommodating the third light-transmitting unit 12, so that the third light-transmitting unit 12 is filled in the light-transmitting hole 141. In some embodiments, external light may sequentially pass through the protective cover 50, the filter protection layer 40, the color filter layer 30, the light-emitting layer 20, the third light-transmitting unit 12 and the substrate 13.

[0038] See also Figure 2, the auxiliary layer 10 may further include diffusion particles 121 to process the light. In some embodiments, the diffusion particles 121 may increase the field of view. In some embodiments, the diffusion particles 121 may increase the field of view by 1.5 times. In some embodiments, the diffusion particles 121 may diffusely reflect the light to reduce the reflectivity of the light. In some embodiments, the diffusion particles 121 may be silicon oxide diffusion particles and / or silicon oxynitride diffusion particles, etc., without limitation. In some embodiments, the particle size of the diffusion particles 121 may be 5-20 nm.

[0039] In some embodiments, the diffusion particles 121 may be distributed in the end of the third light-transmitting unit 12 close to the substrate 13. In some embodiments, the diffusion particles 121 may be disposed between the third light-transmitting unit 12 and the substrate 13 to form an ion layer. In some embodiments, the diffusion particles 121 may be formed on the surface of the third light-transmitting unit 12 facing the substrate 13 or on the surface of the substrate 13 facing the third light-transmitting unit 12 by CVD (Chemical Vapor Deposition) or physical deposition to form an ion layer.

[0040] See also Figure 1 The light-emitting layer 20 may have pixels, such as R (red) pixels, B (blue) pixels, G (green) pixels, W (white) pixels, or pixels that emit infrared light. The light-emitting layer 20 may select, design, and arrange pixels according to actual needs or the type requirements of the display screen assembly 100, which is not limited here. The light-emitting layer 20, such as pixels, may emit light under the drive of the auxiliary layer 10, such as the driving circuit 11. It can be understood that the light-emitting layer 20 may be set differently based on the type of the display screen assembly 100. Specifically, the light-emitting layer 20 may be set corresponding to the type of the display screen assembly 100.

[0041] In some embodiments, the first light-transmitting unit 21 on the light-emitting layer 20 may be disposed between two adjacent pixels. In some embodiments, the first light-transmitting unit 21 may be disposed opposite to the third light-transmitting unit 12, so that light outside the display screen assembly 100 may sequentially pass through the first light-transmitting unit 21 and the third light-transmitting unit 12. In some embodiments, the material of the first light-transmitting unit 21 may be OC glue. In some embodiments, the first light-transmitting unit 21 may be a negative photoresist insulating photosensitive glue, and of course, it may also be other materials. In some embodiments, the refractive index of the first light-transmitting unit 21 is greater than the refractive index of the third light-transmitting unit 12, so that the light entering the display screen assembly 100 may be totally reflected, and the light may be further adjusted to achieve the effect of focusing or collimating. Of course, in other embodiments, the refractive index of the first light-transmitting unit 21 may also be less than or equal to the refractive index of the third light-transmitting unit 12.

[0042] See also Figure 3 , Figure 3 for Figure 1 The auxiliary layer 10 and the light-emitting layer 20 in the embodiment shown are structural diagrams of the cooperation in some embodiments.

The pixel definition layer 22, the cathode layer 23, and the color filter layer 30 are stacked in sequence. The pixel definition layer 22 can limit the size and density of the pixel through the installation space 201, and thus can also limit the resolution of the display screen assembly 100. The driving circuit 11 is electrically connected with the anode 25, the light-emitting unit 24, and the cathode layer 23 in sequence to form a circuit loop, so that the driving circuit 11 can drive the light-emitting unit 24 to emit light. The light-emitting unit 24 can be used as the light-emitting body of the pixel, and can emit red, blue or green light. There can be multiple light-emitting units 24, and the number, light-emitting color, arrangement method, etc. are set according to actual needs. In the plurality of installation spaces 201 and the plurality of light emitting units 24, the installation spaces 201 correspond to the light emitting units 24 one by one, and one light emitting unit 24 is installed in one installation space 201. In some embodiments, the anode 25 may be disposed in the auxiliary layer 10, and thus the anode 25 may not be a part of the light emitting layer 20.

[0043] In some embodiments, the pixel definition layer 22 is provided with a light-through hole 221 to accommodate the first light-transmitting unit 21, so that the first light-transmitting unit 21 is filled in the light-through hole 221. In some embodiments, the light-through hole 221 is provided between two adjacent installation spaces 201.

[0044] The pixel definition layer 22 is provided with a light-through hole 221 , and the first light-transmitting unit 21 is disposed in the light-through hole 221 , so that the transmittance of the pixel definition layer 22 is improved.

[0045] See also Figure 1, the second light-transmitting unit 31 on the color filter layer 30 can be arranged opposite to the first light-transmitting unit 21, so that the light outside the display screen assembly 100 can pass through the second light-transmitting unit 31, the first light-transmitting unit 21 and the third light-transmitting unit 12 in sequence. In some embodiments, the material of the second light-transmitting unit 31 can be OC glue. In some embodiments, the second light-transmitting unit 31 can be a negative photoresist insulating photosensitive glue, of course, it can also be other. In some embodiments, the refractive index of the second light-transmitting unit 31 can be greater than the refractive index of the third light-transmitting unit 12, so that the light entering the display screen assembly 100 can be totally reflected, and the light can be further adjusted to achieve the effect of focusing or collimation. In some embodiments, the refractive index of the second light-transmitting unit 31 can be greater than or equal to the refractive index of the first light-transmitting unit 21, so that the light entering the display screen assembly 100 can be totally reflected, and the light can be further adjusted to achieve the effect of focusing or collimation. Of course, in other embodiments, the refractive index of the second light-transmitting unit 31 can also be less than the refractive index of the first light-transmitting unit 21.

[0046] In some embodiments, the refractive index of the second light-transmitting unit 31 may be 1.9, 1.8 or 1.7.

[0047] See also Figure 4 , Figure 4 for Figure 1 The auxiliary layer 10 in the embodiment shown is a schematic diagram of the structure of the light-emitting layer 20 and the color filter layer 30 in some embodiments. The color filter layer 30 may include a plurality of filter units 33 and a black matrix 32 arranged between two adjacent filter units 33. Among the plurality of filter units 33 and a plurality of pixels such as the light-emitting unit 24, the filter units 33 correspond to the pixels such as the light-emitting unit 24 one by one and are arranged relatively, so that the light emitted by the pixel such as the light-emitting unit 24 can pass through the filter unit 33, so as to adjust the chromaticity of the light emitted by the pixel such as the light-emitting unit 24.

[0048] In some embodiments, the R pixel, such as the light emitting unit 24, emits red light, and the red light passes through the filter unit 33, such as a red filter, to form red light, so that the filter unit 33, such as a red filter, adjusts the chromaticity of the red light emitted by the R pixel, such as the light emitting unit 24.

[0049] In some embodiments, the B pixel, such as the light emitting unit 24, emits blue light, and the blue light passes through the filter unit 33, such as a blue filter, to form blue light, so that the filter unit 33, such as a blue filter, adjusts the chromaticity of the blue light emitted by the B pixel, such as the light emitting unit 24.

[0050] In some embodiments, a G pixel such as the light emitting unit 24 emits green light, and the green light passes through the filter unit 33 such as a green filter to form green light, so that the filter unit 33 such as a green filter adjusts the chromaticity of the green light emitted by the G pixel such as the light emitting unit 24.

[0051] It can be understood that the filter unit 33 can improve the chromaticity uniformity of the light emitted by the pixel, such as the light emitting unit 24 .

[0052] In some embodiments, the black matrix 32 is provided with a perforation 321 to accommodate the second light-transmitting unit 31, so that the second light-transmitting unit 31 is filled in the perforation 321. In some embodiments, the second light-transmitting unit 31 can be arranged between two adjacent filter units 33. In some embodiments, the black matrix 32 can be omitted, and the space where the black matrix 32 is located can be filled with other materials in the color filter layer 30, or filled with the filter protection layer 40.

[0053] The black matrix 32 has a through hole 321 , and the second light-transmitting unit 31 is disposed in the through hole 321 , so that the transmittance of the black matrix 32 is improved.

[0054] See also Figure 5 , Figure 5 for Figure 1 The structure diagram of the display screen assembly 100 in other embodiments of the embodiment shown in the figure. The display screen assembly 100 may also include an encapsulation layer 60, and the light-emitting layer 20, the encapsulation layer 60, and the color filter layer 30 are sequentially stacked. The encapsulation layer 60 can encapsulate the light-emitting layer 20 and protect the light-emitting layer 20.

[0055] See also Figure 6 , Figure 6 for Figure 5 The encapsulation layer 60 in some embodiments is shown in the embodiment. The encapsulation layer 60 includes a first sub-encapsulation layer 61 and a second sub-encapsulation layer 62. The light-emitting layer 20, the first sub-encapsulation layer 61, the second sub-encapsulation layer 62, and the color filter layer 30 are stacked in sequence.

[0056] In some embodiments, the refractive index of the first sub-encapsulation layer 61 is less than the refractive index of the second sub-encapsulation layer 62, thereby improving the low light extraction efficiency caused by total reflection inside the display assembly 100. Of course, the refractive index of the first sub-encapsulation layer 61 may also be greater than or equal to the refractive index of the second sub-encapsulation layer 62.

[0057] In some embodiments, the first sub-encapsulation layer 61 may be an OC (Over Coating) layer, and the first sub-encapsulation layer 61 may be made by a coating process, thereby ensuring the flatness of the film layer in a thinner thickness and reducing the stress of the second sub-encapsulation layer 62. In some embodiments, the material of the first sub-encapsulation layer 61 may be OC glue. In some embodiments, the first sub-encapsulation layer 61 may be a negative photoresist insulating photosensitive glue, and of course, it may also be other materials.

[0058] In some embodiments, the thickness of the first sub-encapsulation layer 61 may be 3-6 μm to reduce the thickness of the entire encapsulation layer 60 .

[0059] In some embodiments, the second sub-encapsulation layer 62 may be a CVD (Chemical Vapor Deposition) layer.

The display screen assembly 100 may also include a touch layer 70, and the light emitting layer 20 and the encapsulation layer 60, the touch layer 70, and the color filter layer 30 are stacked in sequence. The setting of the touch layer 70 enables the display screen assembly 100 to have both touch function and display function.

[0061] See also Figure 1 , the filter protection layer 40 may include a light-gathering area 41. The light-gathering area 41 has a positive refractive power to converge light, increase the field of view, increase the amount of light entering, and may also shape the light, such as straightening. In some embodiments, the light-gathering area 41 may be provided with at least one microlens. In some embodiments, the light-gathering area 41 may be arranged opposite to the second light-transmitting unit 31, so that the light outside the display screen assembly 100 sequentially passes through the light-gathering area 41, the second light-transmitting unit 31, the first light-transmitting unit 21, and the third light-transmitting unit 12.

[0062] See also Figure 8 , Figure 8 for Figure 1 The color filter layer 30 and the filter protection layer 40 in the embodiment shown are schematic diagrams of the structure of the cooperation in some embodiments. The filter protection layer 40 may include a first filter protection layer 42 and a second filter protection layer 43. The color filter layer 30, the first filter protection layer 42, the second filter protection layer 43, and the protective cover plate 50 may be stacked in sequence.

[0063] In some embodiments, within the focusing area 41, the first filter protection layer 42 has a concave surface 421 on the side away from the color filter layer 30, and the second filter protection layer 43 has a convex surface 431 on the side close to the color filter layer 30. The concave surface 421 and the convex surface 431 are in seamless contact and cooperation, thereby converging the light outside the display screen assembly 100 and increasing the field of view angle.

[0064] In some embodiments, the refractive index of the first light filtering protective layer 42 is greater than the refractive index of the second light filtering protective layer 43, so as to achieve the effect of converging light in the focusing area 41. In some embodiments, the refractive index of the first light filtering protective layer 42 is less than the refractive index of the second light transmitting unit 31. In some embodiments, the refractive index of the first light filtering protective layer 42 may be 1.75.

[0065] See also Fig. 9 , Fig. 9 for Figure 1 Schematic diagram of the structure of the protective cover plate 50 in other embodiments in the illustrated embodiment. The protective cover plate 50 can serve as the outer surface of the display screen assembly 100 for the user to touch, and can play a role in protecting the display screen assembly 100. In some embodiments, the protective cover plate 50 may include a glass cover plate 51. In some embodiments, the glass cover plate 51 may be a UTG (Ultra-Thin Glass) cover plate. In some embodiments, the protective cover plate 50 may include a flexible film 52 such as a PET (Polyethylene terephthalate) film stacked with the glass cover plate 51 such as a UTG cover plate. The flexible film 52 is arranged on the side of the glass cover plate 51 such as a UTG cover plate away from the light-emitting layer 20.
