[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1 , Figure 1Schematic diagram of the structure of the display screen assembly in some embodiments of the present application. The display screen assembly 100 can further improve the visual effect by weakening the reflection diffraction phenomenon and improving the color separation phenomenon. The display screen assembly 100 can be an AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode or active matrix organic light emitting diode) display module, or a Micro LED (micro light emitting diode) display module, or even an LCD (Liquid Crystal Display) display module or a QLED (Quantum dot light-emitting diode, Quantumdots Light-emitting Diodes) display module. The type of the display screen assembly 100 is not limited here.

[0032] In some embodiments, the display screen assembly 100 may be a flexible display screen.

[0033] See also Figure 1 The display screen assembly 100 may include an auxiliary layer 10, a light-emitting layer 20, a color filter layer 30 and a protective layer 40 which are stacked in sequence. A driving circuit 11 is provided in the auxiliary layer 10, and the light-emitting layer 20 is driven to emit light by the driving circuit 11. The color filter layer 30 is used to adjust the chromaticity of the light emitted by the light-emitting layer 20, so that the display screen assembly 100 presents a pattern or picture with good chromaticity. The protective layer 40, as the outer surface of the display screen assembly 100, is used to protect the display screen assembly 100. The light-emitting layer 20 may emit light with the assistance of the auxiliary layer 10, such as the driving circuit 11, and the light passes through the color filter layer 30 to adjust the chromaticity, and then passes through the protective layer 40 to emit from the display screen assembly 100 for display. The protective layer 40 may weaken the reflection and diffraction phenomenon, improve the color separation phenomenon, and further improve the visual effect.

[0034] See also Figure 1 , a driving circuit 11 may be provided in the auxiliary layer 10, and 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, an insulating layer, and a substrate layer. Of course, the stack may not be limited to the embodiments listed here, and may also include other single stacks.

[0035] See also Figure 1The 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.

[0036] See also Figure 2 , Figure 2 for Figure 1 The schematic diagram of the structure of the light-emitting layer 20 in some embodiments of the embodiment shown. The light-emitting layer 20 may include a pixel definition layer 21 having a plurality of installation spaces 201, a cathode layer 22 stacked with the pixel definition layer 21, a light-emitting unit 23 arranged in the installation space 201 and electrically connected to the cathode layer 22, and an anode 24 electrically connected to the light-emitting unit 23 and the driving circuit 11 respectively. The pixel definition layer 21, the cathode layer 22, and the color filter layer 30 are stacked in sequence. The pixel definition layer 21 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 24, the light-emitting unit 23, and the cathode layer 22 in sequence to form a circuit loop, so that the driving circuit 11 can drive the light-emitting unit 23 to emit light. The light-emitting unit 23 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 23, and the number, light color, arrangement method, etc. are set according to actual needs. In the plurality of installation spaces 201 and the plurality of light emitting units 23, the installation spaces 201 correspond to the light emitting units 23 one by one, and one light emitting unit 23 is installed in one installation space 201. In some embodiments, the anode 24 may be disposed in the auxiliary layer 10, and thus the anode 24 may not be a part of the light emitting layer 20.

[0037] See also Figure 3 , Figure 3 for Figure 1 The illustrated embodiment 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 31 and a black matrix 32 disposed between two adjacent filter units 31. Among the plurality of filter units 31 and the plurality of pixels, such as the light emitting units 23, the filter units 31 correspond to the pixels, such as the light emitting units 23, and are disposed relatively, so that the light emitted by the pixels, such as the light emitting units 23, can pass through the filter units 31, so as to adjust the chromaticity of the light emitted by the pixels, such as the light emitting units 23.

[0038] In some embodiments, the R pixel, such as the light emitting unit 23, emits red light, and the red light passes through the filter unit 31, such as a red filter, to form red light, so that the filter unit 31, such as a red filter, adjusts the chromaticity of the red light emitted by the R pixel, such as the light emitting unit 23.

[0039] In some embodiments, a B pixel, such as the light emitting unit 23, emits blue light, and the blue light passes through the filter unit 31, such as a blue filter, to form blue light, so that the filter unit 31, such as a blue filter, adjusts the chromaticity of the blue light emitted by the B pixel, such as the light emitting unit 23.

[0040] In some embodiments, a G pixel, such as the light emitting unit 23, emits green light, and the green light passes through the filter unit 31, such as a green filter, to form green light, so that the filter unit 31, such as a green filter, adjusts the chromaticity of the green light emitted by the G pixel, such as the light emitting unit 23.

[0041] It can be understood that the filter unit 31 can improve the chromaticity uniformity of the light emitted by the pixel, such as the light emitting unit 23 .

[0042] See also Figure 4 , Figure 4 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 50, and the light-emitting layer 20, the encapsulation layer 50, and the color filter layer 30 are sequentially stacked. The encapsulation layer 50 can encapsulate the light-emitting layer 20 and protect the light-emitting layer 20.

[0043] See also Figure 5 , Figure 5 for Figure 4 The schematic diagram of the structure of the light-emitting layer 20, the encapsulation layer 50 and the color filter layer 30 in some embodiments shown in the embodiment. The black matrix 32 can be arranged in the encapsulation layer 50 instead of in the color filter layer 30. By adjusting the distance between the black matrix 32 and the light-emitting layer 20, the black matrix 32 is closer to the light-emitting layer 20 than the filter unit 31.

[0044] In some embodiments, the change in the position of the black matrix 32 can at least reduce the reflectivity of the cathode layer 22 to light reflection, thereby weakening the reflection diffraction phenomenon, improving the color separation phenomenon, and further improving the visual effect.

[0045] In some embodiments, the change in the position of the black matrix 32 can at least shorten the distance between the light-emitting layer 20 , such as the light-emitting unit 23 , and the black matrix 32 in the thickness direction of the light-emitting layer 20 , which can effectively improve the brightness attenuation and color shift at large viewing angles.

[0046] See also Figure 5 The black matrix 32 is provided with a plurality of perforations 501. Among the plurality of filter units 31 and the plurality of perforations 501, the filter units 31 correspond to the perforations 501 one by one and are arranged relatively to each other, so that the light emitted by the light-emitting layer 20 passes through the perforations 501 and the filter units 31 in sequence.

[0047] In some embodiments, the through-hole 501 may be filled with remaining material in the encapsulation layer 50 .

[0048] In some embodiments, the space between two adjacent filter units 31 in the color filter layer 30 may be filled with the protective layer 40, so that the filter unit 31 is disposed in the protective layer 40. Of course, the space between two adjacent filter units 31 in the color filter layer 30 may also be filled with the remaining material in the color filter layer 30.

The display screen assembly 100 may also include a touch layer 60, and the light emitting layer 20 and the encapsulation layer 50, the touch layer 60, and the color filter layer 30 are stacked in sequence. The setting of the touch layer 60 enables the display screen assembly 100 to have both touch function and display function.

[0050] See also Figure 7 , Figure 7 for Figure 1 The schematic diagram of the structure of the light emitting layer 20 in the embodiment shown cooperates with the color filter layer 30 and the protective layer 40 in other embodiments. The protective layer 40 may include a first modulation layer 41 stacked with the color filter layer 30. The first modulation layer 41 can weaken the reflection and diffraction phenomenon, improve the color separation phenomenon, and further improve the visual effect.

[0051] In some embodiments, the first modulation layer 41 may be provided with a plurality of light holes 401. Among the plurality of light filter units 31 and the plurality of light holes 401, the light holes 401 correspond to the light filter units 31 one by one and are arranged relatively to each other, so that the light emitted by the light emitting layer 20, such as the light emitting unit 23, can sequentially pass through the light filter units 31 and the light holes 401. The first modulation layer 41 can be used to spatially modulate the amplitude and / or phase of the reflected light incident into the first modulation layer 41.

[0052] In some embodiments, the light-through hole 401 of the first modulation layer 41 may be filled with the remaining material in the protection layer 40 .

[0053] In some embodiments, the orthographic projection of the first modulation layer 41 on the black matrix 32 is located within the black matrix 32 , or coincides with the black matrix 32 .

[0054] In some embodiments, the first modulation layer 41 is a diffraction grating, and thus may be referred to as a first diffraction grating.

[0055] See also Figure 8 , Figure 8 for Figure 4 The schematic diagram of the structure of the light-emitting layer 20 in the embodiment shown cooperates with the encapsulation layer 50, the color filter layer 30, and the protective layer 40 in other embodiments. The black matrix 32 can be arranged in the encapsulation layer 50, but not in the color filter layer 30. Among the multiple light-through holes 401 and the multiple perforations 501, the light-through holes 401 correspond to the perforations 501 one by one and are arranged relatively, so that the light emitted by the light-emitting layer 20, such as the light-emitting unit 23, passes through the perforations 501, the filter unit 31 and the light-through holes 401 in sequence.

The first modulation layer 41, in cooperation with the first body 411 and the first grating structure layer 412, may be referred to as a first diffraction grating. Of course, the first grating structure layer 412 may also be replaced by a first light scattering pattern layer or a first binary optical layer.
