[0034] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0035] Figure 1 is a structural diagram of a display panel provided by an embodiment of the present invention, Figure 2 yes Figure 1 The schematic diagram of the cross-sectional structure of the display panel provided along the section line AA' is combined with Figure 1 and Figure 2 As shown, the display panel 10 provided by the embodiment of the present invention includes a display area 11, and the display area 11 includes a plurality of light-emitting elements 111; the display panel 10 also includes a shading layer 12 located on the light-emitting side of the light-emitting element, and the shading layer 12 includes a plurality of shading units 121. Along the thickness direction of the display panel 10 (the X direction as shown in the figure), the shading unit 121 at least partially overlaps with the gap between two adjacent light-emitting elements 111; the display panel 10 also includes a reflection adjustment unit 13 located on the side of the shading layer 12 away from the light-emitting element. Along the thickness direction of the display panel (the X direction as shown in the figure), the reflection adjustment unit 13 overlaps with at least part of the shading unit 121.

[0036] Specifically, the display panel 10 includes a display area 11, and the display area 11 includes a plurality of light-emitting elements 111. The light-emitting elements 111 emit light to realize the display function of the display panel 10. Optionally, the display panel 10 may also include a pixel circuit (not shown) located in the display area, and the pixel circuit is electrically connected to the light-emitting element for providing a display drive signal to the light-emitting element to ensure that the light-emitting element emits light normally. Furthermore, the pixel circuit may include a thin film transistor and a storage capacitor. For example, the pixel circuit may be a "2T1C" pixel circuit formed by two thin film transistors and a storage capacitor, or the pixel circuit may be a "7T1C" pixel circuit formed by seven thin film transistors and a storage capacitor, or the pixel circuit may also include other structures. The embodiment of the present invention does not limit the specific setting method of the pixel circuit. Optionally, the light-emitting element 111 may be an organic light-emitting diode, a micro light-emitting diode or a liquid crystal light-emitting element. The embodiment of the present invention also does not limit the specific type of the light-emitting element 111.

[0037] Furthermore, the display panel 10 provided in the embodiment of the present invention also includes a light-shielding layer 12 located on the light-emitting layer of the light-emitting element 111. The light-shielding layer includes a plurality of light-shielding units 121. Along the thickness direction of the display panel, the light-shielding units 121 cover the gaps between two adjacent light-emitting elements 111. In other words, the light-shielding units 121 define the light-emitting areas of the light-emitting elements 111. In this way, the light-shielding units 121 can prevent light crosstalk between adjacent light-emitting elements 111, thereby improving the display effect of the display panel.

[0038] Furthermore, the display panel 10 provided in an embodiment of the present invention also includes a reflection adjustment unit 13 located on a side of the light-shielding layer 12 away from the light-emitting element 111. Along the thickness of the display panel, the reflection adjustment unit 13 overlaps at least partially with the light-shielding unit 121. In this way, the reflection adjustment unit 13 can adjust the reflectivity of the display panel 10 surface, reducing the reflection differences between different areas in the display area 11. For example, the reflection difference between the normal display area and the photosensitive area in the display area 11 is reduced. This ensures that the reflectivity of different areas in the display area is the same or similar, ensuring that different areas in the display area reflect the same or similar degree of ambient light, ensuring that the ambient light has the same or similar impact on the light emitted by different areas in the display area, and ensuring a well-balanced display of the display panel. Furthermore, by adjusting the reflectivity of the display panel 10 surface through the reflection adjustment unit 13, the reflection differences between different areas in the display area 11 are reduced, and the boundaries between different areas in the display area 11 are blurred. This avoids the obvious boundary between different display areas when the display is not in the display state due to the large reflection difference, such as the obvious boundary between the normal display area and the photosensitive area, thereby improving the user experience.

[0039] It should be noted that the embodiment of the present invention does not limit the shape of the light emitting elements and the arrangement of the light emitting elements. Figure 1 Only one feasible shape and arrangement of light emitting elements is used as an example for description. Other shapes and arrangements of light emitting elements also fall within the protection scope of the embodiments of the present invention.

[0040] It should also be noted that, in order to clearly illustrate different structures, the embodiments of the present invention are only shown in FIG. Figure 2 The reflection adjustment unit is shown in the cross-sectional view. In subsequent embodiments, the reflection adjustment unit is also only shown in the cross-sectional view and is not shown in the top view. This does not mean that the reflection adjustment unit does not exist in the drawing.

[0041] In summary, the display panel provided by the embodiment of the present invention, by arranging a shading layer on the light-emitting side of the light-emitting element, avoids light crosstalk between adjacent light-emitting elements through the shading layer, thereby ensuring the display effect of the display panel; at the same time, by adding a reflection adjustment unit, the reflectivity of the surface of the display panel is adjusted by the reflection adjustment unit. On the one hand, it can avoid the reflected light of external light affecting the normal light emission of the display panel. On the other hand, the reflectivity of different areas in the display area can be adjusted through the reflection adjustment unit, thereby avoiding display differences caused by different reflectivities in different areas, thereby improving the display effect of the display panel.

[0042] On the basis of the above embodiment, the reflectivity of the reflection adjustment unit 13 is smaller than the reflectivity of the light shielding unit 121 .

[0043] For example, Figure 2As shown, the reflection adjustment unit 13 is located on the side of the shading unit 121 away from the light emitting element 111, so the reflection adjustment unit 13 replaces the shading unit 121 to reflect the light from the external ambient light incident on the display panel. The technical solution of the embodiment of the present invention sets the reflectivity of the reflection adjustment unit 13 to be less than the reflectivity of the shading unit 121, which can reduce the reflection of the external ambient light and reduce the emission of the reflected light from the display panel, that is, reduce the interference of the external ambient light on the light emission of the light emitting element 111, which can improve the display effect of the display panel. For example, by setting the reflectivity of the reflection adjustment unit 13 to be less than the reflectivity of the shading unit 121, it can be avoided that the display content of the display panel cannot be seen clearly when the external ambient light intensity is high.

[0044] Based on the above embodiments, continue to refer to Figure 1 As shown, in the display panel 10 provided by an embodiment of the present invention, the display area 11 may include a first display area 11-1 and a second display area 11-2, the first display area 11-1 includes a photosensitive area, and the second display area 11-2 at least partially surrounds the first display area 11-1; along the first direction, the reflectivity of the display panel 10 gradually increases; the first direction is the direction in which the second display area 11-2 points to the first display area 11-1.

[0045] Specifically, in an embodiment of the present invention, the display area 11 includes a first display area 11-1 and a second display area 11-2, wherein the second display area 11-2 can be a normal display area, that is, the main display area of ​​the display panel 10, which is mainly responsible for display. The first display area 11-1 can be a high-transmittance display area or a transparent display area. The first display area 11-1 has both display function and light transmission function, that is, the first display area 11-1 can include a photosensitive area, and the photosensitive element corresponding to the area can realize an optical recognition function through the light passing through the first display area 11-1. Specifically, the photosensitive area can be, for example, an optical imaging area or an optical fingerprint recognition area, corresponding to the imaging function or fingerprint recognition function of the display panel. Optionally, since the pixel circuit that drives the light-emitting element is the main shading element, in order to ensure that the transmittance of the first display area is greater than the transmittance of the second display area, the distribution density of the pixel circuit in the first display area can be set to be smaller than the distribution density of the pixel circuit in the second display area. Specifically, the distribution density of the light-emitting elements in the first display area can be set to be smaller than the distribution density of the light-emitting elements in the second display area, or the same pixel circuit in the first display area can be set to drive at least two light-emitting elements, that is, the distribution density of the pixel circuit in the first display area can be reduced by the "one drive many" method. Alternatively, the size of the pixel circuit in the first display area is set to be smaller than the size of the pixel circuit in the second display area to achieve a higher transmittance in the first display area. The embodiment of the present invention does not limit whether the first display area realizes high-transmittance display or transparent display.

[0046] Specifically, since the first display area 11-1 is a high-transmittance display area or a transparent display area, the first display area 11-1 may not be provided with a light-shielding layer 12, or the distribution density of the light-shielding units in the first display area 11-1 is less than the distribution density of the light-shielding units in the second display area 11-2. Figure 1 The first display area 11-1 may not be provided with a light-shielding layer 12 as an example for explanation. This ensures that the first display area 11-1 can transmit light normally, ensuring that the display panel can realize the optical recognition function. The inventors have found that when the first display area 11-1 is not provided with a light-shielding layer 12 or the distribution density of the light-shielding units in the first display area 11-1 is less than the distribution density of the light-shielding units in the second display area 11-2, the film structure (such as the pixel circuit) of the display panel 10 located below the light-shielding layer 12 has a strong reflective effect on the light incident thereon, so that there is a large display difference between the first display area 11-1 and the second display area 11-2, resulting in a display difference between the first display area 11-1 and the second display area 11-2. Moreover, when the display panel 10 is in a non-display state, due to the different reflectivity of the first display area 11-1 and the second display area 11-2, the user can more clearly observe the boundary between the first display area 11-1 and the second display area 11-2, affecting the user experience.

[0047] Based on this, the embodiment of the present invention creatively sets the direction along the second display area 11-2 pointing to the first display area 11-1, and the reflectivity of the display panel 10 gradually increases, so as to reduce the reflectivity difference between the first display area 11-1 and the second display area 11-2, blur the boundary between the first display area 11-1 and the second display area 11-2, avoid the display difference caused by the large difference in reflectivity of different areas and the problem that the first display area 11-1 is obviously visible in the non-display state, thereby improving the display effect of the display panel and the user experience.

[0048] The following describes how to gradually increase the reflectivity of the display panel along the first direction.

[0049] As a feasible implementation method, Figure 3 yes Figure 1 A schematic diagram of a cross-sectional structure of a display panel along the section line BB' is provided. Figure 4 yes Figure 1 Another schematic diagram of a cross-sectional structure of a display panel along the cross-sectional line BB' is provided. Figure 5 yes Figure 1 Another cross-sectional structural diagram of the display panel provided along the section line BB', combined with Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131 ; along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases.

[0050] Specific, combined Figure 3-Figure 5 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, which is arranged on the side of the shading unit 121 away from the light-emitting element 111, and the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the shading unit 121. In this way, the luminous flux of external ambient light reflected on the surface of the display panel 10 can be reduced, thereby reducing the light interference to the display panel 10.

[0051] Furthermore, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases. This gradually increases the exposed area of ​​the light shielding unit 121 along the first direction, thereby gradually increasing the reflectivity of the display panel. By gradually decreasing the coverage area of ​​the first color reflection adjustment unit, the reflectivity of the display panel gradually increases, reducing the reflectivity difference between the first display area and the second display area, blurring the boundary between the first display area and the second display area, and improving the display quality of the display panel and the user experience.

[0052] It should be noted that the embodiment of the present invention does not limit the specific color of the first color reflection adjustment unit. As a feasible configuration, the first color reflection adjustment unit 131 may be a red reflection adjustment unit.

[0053] Next, how to gradually reduce the coverage area of ​​the first color reflection adjustment unit will be described.

[0054] As a feasible implementation method, continue to refer to Figure 1 and Figure 3 As shown, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 corresponding to two adjacent light emitting elements 111 gradually decreases.

[0055] Specifically, such as Figure 3 As shown, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 corresponding to the two adjacent light-emitting elements 111 gradually decreases, so that the exposure area of ​​the shading unit 121 corresponding to the two adjacent light-emitting elements 111 gradually increases. Since the reflectivity of the shading unit 121 is greater than the reflectivity of the first color reflection adjustment unit 131, it is ensured that the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases along the first direction, and the implementation method of gradually reducing the coverage area of ​​the first color reflection adjustment unit 131 is simple and feasible.

[0056] As another possible implementation method, Figure 1 and4 As shown, along the first direction, the first color reflection adjustment unit 131 is not provided on the side of the light shielding unit 121 close to the first display area 11 - 1 and away from the light emitting element 111 .

[0057] Specifically, such as Figure 4 As shown, along the first direction, the first color reflection adjustment unit 131 is not provided on the side of the shading unit 121 closer to the first display area 11-1 and farther from the light-emitting element 111. That is, the area where the shading unit 121 is provided closer to the first display area 11-1 is staggered from the area where the first color reflection adjustment unit 131 is provided. In this way, the exposed area of ​​the shading unit 121 corresponding to two adjacent light-emitting elements 111 can also be gradually increased. Because the reflectivity of the shading unit 121 is greater than the reflectivity of the first color reflection adjustment unit 131, the solution of gradually reducing the coverage area of ​​the first color reflection adjustment unit 131 along the first direction is ensured, and the implementation method of gradually reducing the coverage area of ​​the first color reflection adjustment unit 131 is simple and feasible.

[0058] It should be noted that, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases, as shown in FIG. Figure 3 As shown, in the gap between any two adjacent light-emitting elements 111, the coverage area of ​​the first color reflection adjustment unit at the gap position close to the first display area 11-1 is smaller than the coverage area of ​​the first color reflection adjustment unit at the gap position far from the first display area 11-1; it can also be as shown in FIG. Figure 4 As shown, there are two areas, in which the coverage area of ​​the first color reflection adjustment unit in the area close to the first display area 11-1 is smaller than the coverage area of ​​the first color reflection adjustment unit in the area away from the first display area 11-1, but each area may include gap positions between multiple light-emitting elements 111.

[0059] As another possible implementation, continue to refer to Figure 1 and Figure 5 As shown, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 corresponding to two adjacent light-emitting elements 111 gradually decreases, and the first color reflection adjustment unit 131 is not provided on the side of the shading unit 121 close to the first display area 11-1 and away from the light-emitting element 111.

[0060] Specifically, such as Figure 3As shown, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 corresponding to the two adjacent light-emitting elements 111 gradually decreases, and the first color reflection adjustment unit 131 is not provided on the side of the shading unit 121 close to the first display area 11-1 along the first direction and away from the light-emitting element 111. In this way, the exposed area of ​​the shading unit 121 gradually increases along the first direction. Since the reflectivity of the shading unit 121 is greater than the reflectivity of the first color reflection adjustment unit 131, it is ensured that the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases along the first direction, and the implementation method of gradually reducing the coverage area of ​​the first color reflection adjustment unit 131 is simple and feasible.

[0061] To sum up, the above embodiment realizes that the reflectivity of the display panel gradually increases along the first direction by setting the coverage area of ​​the first color reflection adjustment unit to gradually decrease along the first direction, thereby reducing the reflectivity difference between the first display area and the second display area, blurring the boundary between the first display area and the second display area, avoiding the display difference caused by the large difference in reflectivity of different areas and the problem that the first display area is obviously visible in the non-display state, thereby improving the display effect of the display panel and the user experience.

[0062] Next, how to achieve a gradual increase in the reflectivity of the display panel along the first direction will be described from another perspective.

[0063] Figure 6 yes Figure 1 Another schematic diagram of a cross-sectional structure of a display panel along the cross-sectional line BB' is provided. Figure 7 yes Figure 1 Another cross-sectional structural diagram of the display panel provided along the section line BB', combined with Figure 1 、 Figure 6 and Figure 7 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131 and a second color reflection adjustment unit 132, and the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the second color reflection adjustment unit 132; along the thickness direction of the display panel (the X direction shown in the figure), the reflection adjustment unit 13 covers the shading unit 121 and along the first direction, the coverage area of ​​the second color reflection adjustment unit 132 gradually increases.

[0064] Specific, combined Figure 6 and Figure 7As shown, the reflection adjustment unit 13 covers the shading unit 121 and includes a first color reflection adjustment unit 131 and a second color reflection adjustment unit 132. The reflectivity of the first color reflection adjustment unit 131 and the second color reflection adjustment unit 132 are both lower than the reflectivity of the shading unit 121. In this way, the luminous flux of the external ambient light reflected on the surface of the display panel 10 can be reduced, thereby reducing the interference with the light output of the display panel 10.

[0065] Furthermore, since the reflectivity of the second color reflection adjustment unit 132 is greater than that of the first color reflection adjustment unit 131, the coverage area of ​​the second color reflection adjustment unit 132 is gradually increased along the first direction, thereby ensuring that the reflectivity of the display panel gradually increases along the first direction, reducing the reflectivity difference between the first display area and the second display area, blurring the boundary between the first display area and the second display area, and improving the display effect of the display panel and the user experience.

[0066] It should be noted that the embodiment of the present invention does not limit the specific colors of the first color reflection adjustment unit and the second color reflection adjustment unit. As a feasible setting method, the first color reflection adjustment unit can be a red reflection adjustment unit, and the second color reflection adjustment unit can be a green reflection adjustment unit.

[0067] Next, how to gradually increase the coverage area of ​​the second color reflection adjustment unit will be described.

[0068] As a feasible implementation method, continue to refer to Figure 1 and 6 As shown, along the first direction, the coverage area of ​​the second color reflection adjustment unit 132 corresponding to two adjacent light emitting elements 111 gradually increases.

[0069] Specifically, such as Figure 6 As shown, along the first direction, the coverage area of ​​the second color reflection adjustment unit 132 corresponding to the two adjacent light-emitting elements 111 gradually increases, that is, the coverage area of ​​the first color reflection adjustment unit 131 corresponding to the two adjacent light-emitting elements 111 gradually decreases. Since the reflectivity of the second color reflection adjustment unit 132 is greater than the reflectivity of the first color reflection adjustment unit 131, the solution of gradually increasing the coverage area of ​​the second color reflection adjustment unit 132 along the first direction is realized, and the implementation method of gradually increasing the coverage area of ​​the second color reflection adjustment unit 132 is simple and feasible.

[0070] As another possible implementation, continue to refer to Figure 1 and Figure 7 As shown, along the first direction, the second color reflection adjustment unit 132 is not provided on the side of the light shielding unit 121 close to the second display area 11 - 2 and away from the light emitting element 111 .

[0071] Specifically, such as Figure 7 As shown, along the first direction, the second color reflection adjustment unit 132 is not set on the side of the shading unit 121 close to the second display area 11-2 and away from the light-emitting element 111, that is, the setting area of ​​the shading unit 121 close to the second display area 11-2 is staggered with the setting area of ​​the second color reflection adjustment unit 132, that is, the second color reflection adjustment unit 132 is not set on the shading unit 121 close to the second display area 11-2 in the first direction, but only the first color reflection adjustment unit 131 is set. In this way, the scheme of gradually increasing the coverage area of ​​the second color reflection adjustment unit 132 along the first direction can also be realized, and the implementation method of gradually increasing the coverage area of ​​the second color reflection adjustment unit 132 is simple and feasible.

[0072] It should be noted that, along the first direction, the coverage area of ​​the second color reflection adjustment unit 132 gradually increases, as shown in FIG. Figure 6 As shown, in the gap between any two adjacent light-emitting elements 111, the coverage area of ​​the second color reflection adjustment unit at the gap position close to the first display area 11-1 is larger than the coverage area of ​​the second color reflection adjustment unit at the gap position away from the first display area 11-1; it can also be as shown in FIG. Figure 7 As shown, there are two areas, in which the coverage area of ​​the second color reflection adjustment unit in the area close to the first display area 11-1 is larger than the coverage area of ​​the second color reflection adjustment unit in the area away from the first display area 11-1, but each area may include gap positions between multiple light-emitting elements 111.

[0073] To sum up, the above embodiment realizes that the reflectivity of the display panel gradually increases along the first direction by setting the coverage area of ​​the second color reflection adjustment unit to gradually increase along the first direction, reduces the reflectivity difference between the first display area and the second display area, blurs the boundary between the first display area and the second display area, avoids the display difference caused by the large difference in reflectivity of different areas and the problem that the first display area is obviously visible in the non-display state, thereby improving the display effect of the display panel and the user experience.

[0074] Based on the above embodiments, continue to refer to Figure 6As shown, along the thickness direction of the display panel (the X direction shown in the figure), the reflection adjustment unit 13 covers the shading unit 121; the reflection adjustment unit 13 includes a first color reflection adjustment unit 131 and a second color reflection adjustment unit 132, and the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the second color reflection adjustment unit 132; the coverage area of ​​the first color reflection adjustment unit 131 is M, and the coverage area of ​​the second color reflection adjustment unit 132 is N; along the first direction, M / (M+N) gradually decreases.

[0075] For example, Figure 6 As shown, along the first direction, the coverage area of ​​the first color reflection adjustment unit 131 gradually decreases, and the coverage area of ​​the second color reflection adjustment unit 132 gradually increases, that is, M / (M+N) gradually decreases, and N / (M+N) gradually increases. In this way, it is ensured that along the first direction, the reflectivity of the display panel gradually increases, and it is ensured that the reflectivity difference between the first display area and the second display area can be reduced, and the boundary between the first display area and the second display area is blurred, thereby avoiding display differences caused by large differences in reflectivity in different areas and the problem that the first display area is obviously visible when not in the display state.

[0076] The above embodiment illustrates how to gradually increase the reflectivity of the display panel along the first direction by taking the setting method of the first color reflection adjustment unit and the setting method of the second color reflection adjustment unit as examples. Next, how to adjust the reflectivity of the display panel in the first direction to gradually increase will be described from another perspective.

[0077] Figure 8 FIG. 1 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 8 As shown, the display panel 10 also includes a third display area 11-3, the third display area 11-3 at least partially surrounds the first display area 11-1, and the second display area 11-2 at least partially surrounds the third display area 11-3; the reflectivity of the third display area 11-3 is greater than the reflectivity of the second display area 11-2, and less than the reflectivity of the first display area 11-2.

[0078] Exemplarily, the display area 11 of the display panel 10 may further include a third display area 11-3, and the third display area 11-3 may be located between the first display area 11-1 and the second display area 11-2, that is, the third display area 11-3 at least partially surrounds the first display area 11-1, and the second display area 11-2 at least partially surrounds the third display area 11-3. The third display area 11-3 can serve as a transition area between the first display area 11-1 and the second display area 11-2, specifically, it can be a transition area between the reflectivity of the first display area 11-1 and the reflectivity of the second display area 11-2, that is, the reflectivity of the third display area 11-3 is greater than the reflectivity of the second display area 11-2, and less than the reflectivity of the first display area 11-2. In this way, along the first direction, the reflectivity of the display panel gradually increases, which can reduce the reflectivity difference between the first display area 11-1 and the second display area 11-2, blur the boundary between the first display area 11-1 and the second display area 11-2, avoid display differences caused by large differences in reflectivity in different areas and the problem that the first display area 11-1 is obviously visible when not in the display state, thereby improving the display effect of the display panel and the user experience.

[0079] Furthermore, the first display area 11-1 serves as a high-transmittance display area or a transparent display area, the second display area 11-2 serves as a normal display area, and the third display area 11-3 can also serve as a transition area between the transmittance of the first display area 11-1 and the transmittance of the second display area 11-2. For example, the distribution density of pixel circuits in the third display area 11-3 is set to be greater than the distribution density of pixel circuits in the first display area 11-1 and less than the distribution density of pixel circuits in the second display area 11-2, or the distribution density of light-emitting elements in the third display area 11-3 is set to be greater than the distribution density of light-emitting elements in the first display area 11-1 and less than the distribution density of light-emitting elements in the second display area 11-2, so as to ensure a uniform transition of the display effect between the first display area and the second display area, avoid display differences caused by different distribution densities of pixel circuits or light-emitting elements, and ensure good display uniformity of the display panel.

[0080] Next, it is described how to set the reflectivity of the third display area to be greater than the reflectivity of the second display area and less than the reflectivity of the first display area.

[0081] As a feasible implementation method, Figure 9 yes Figure 8 A schematic diagram of the cross-sectional structure of the display panel along the section line CC' is provided. Figure 10 yes Figure 8 A schematic cross-sectional view of a display panel along the cross-sectional line D-D' is provided. Figure 11 yes Figure 8 A schematic diagram of a cross-sectional structure of a display panel along the cross-sectional line EE' is provided, combined with 8- Figure 11As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, a second color reflection adjustment unit 132 and a third color reflection adjustment unit 133; the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the third color reflection adjustment unit 133, and the reflectivity of the third color reflection adjustment unit 133 is less than the reflectivity of the second color reflection adjustment unit 132; the first color reflection adjustment unit 131 covers the shading unit located in the second display area 11-2, the third color reflection adjustment unit 133 covers the shading unit located in the third display area 11-3, and the second color reflection adjustment unit 132 covers the shading unit located in the first display area 11-1.

[0082] Specific, combined Figures 8-11 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, a second color reflection adjustment unit 132 and a third color reflection adjustment unit 133, and the reflectivity of the first color reflection adjustment unit 131, the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133 are all less than the reflectivity of the shading unit 121, so that the luminous flux of the external ambient light reflected on the surface of the display panel 10 can be reduced, thereby reducing the interference with the light output of the display panel 10.

[0083] Furthermore, among the first color reflection adjustment unit 131, the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133, the reflectivity of the first color reflection adjustment unit 131 is the smallest, the reflectivity of the second color reflection adjustment unit 132 is the largest, and the reflectivity of the third color reflection adjustment unit 133 is in the middle. Therefore, the first color reflection adjustment unit 131 is set to cover the shading unit located in the second display area 11-2, the third color reflection adjustment unit 133 is set to cover the shading unit located in the third display area 11-3, and the second color reflection adjustment unit 132 is set to cover the shading unit located in the first display area 11-1. The shading unit can ensure that the reflectivity among the second display area 11-2, the third display area 11-3 and the first display area 11-1 gradually increases, that is, along the first direction, the reflectivity of the display panel gradually increases, so as to reduce the reflectivity difference between the first display area 11-1 and the second display area 11-2, blur the boundary between the first display area 11-1 and the second display area 11-2, avoid the display difference caused by the large difference in reflectivity of different areas and the problem that the first display area 11-1 is obviously visible when not in the display state, thereby improving the display effect of the display panel and the user experience.

[0084] It should be noted that the second color reflection adjustment unit 132 covers the shading unit located in the first display area 11-1. At this time, a shading unit can be provided in the first display area 11-1. In order to ensure that the transmittance of the first display area 11-1 is greater than the transmittance of the second display area, the distribution density of the shading unit in the first display area is smaller than the distribution density of the shading unit in the second display area, and / or the size of the shading unit in the first display area is smaller than the size of the shading unit in the second display area.

[0085] It should also be noted that the embodiment of the present invention does not limit the specific colors of the first color reflection adjustment unit, the second color reflection adjustment unit, and the third color reflection adjustment unit. As a feasible setting method, the first color reflection adjustment unit can be a red reflection adjustment unit, the second color reflection adjustment unit can be a green reflection adjustment unit, and the third color reflection adjustment unit can be a blue reflection adjustment unit.

[0086] As another possible implementation, Figure 12 yes Figure 8 Another schematic cross-sectional view of a display panel along the cross-sectional line DD' is provided. Figure 13 yes Figure 8 Another cross-sectional structural diagram of the display panel provided along the cross-sectional line EE' is shown in FIG. Figure 8 、 Figure 9 、 Figure 12 and Figure 13 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, and the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the shading unit 121; the first color reflection adjustment unit 131 covers the shading unit 121 located in the second display area 11-2, and along the thickness direction of the display panel (the X direction shown in the figure), the shading unit 121 located in the third display area 11-3 overlaps with the reflection adjustment unit 13 at most.

[0087] Specific, combined Figure 8 、 Figure 9 、 Figure 12 and Figure 13 As shown, the reflection adjustment unit 13 includes at least a first color reflection adjustment unit 131 and the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the shading unit 121, and the first reflection adjustment unit 131 covers the shading unit 121 located in the second display area 11-2, so that at least the luminous flux of the external ambient light reflected on the surface of the second display area 11-2 can be reduced, and the light interference of the external ambient light in the second display area 11-2 on the display panel 10 can be reduced.

[0088] Further, combined Figure 8 、 Figure 9 、 Figure 12 and Figure 13 As shown, the first color reflection adjustment unit 131 covers the shading unit 121 located in the second display area 11-2, thereby ensuring that the second display area 11-2 has a lower reflectivity. At the same time, along the thickness direction of the display panel (the X direction shown in the figure), the shading unit 121 located in the third display area 11-3 overlaps with the reflection adjustment unit 13 at most. In other words, the third display area 11-3 is provided with a partial reflection adjustment unit or no reflection adjustment unit. Figure 12 The third display area 11-3 is not provided with the reflection adjustment unit 13. In this case, the reflectivity of the third display area 11-3 is necessarily greater than the reflectivity of the second display area 11-2. At the same time, the first display area 11-2 is not provided with a shading unit or the distribution density of the shading unit is less than the distribution density of the shading units in the second display area 11-2 and the third display area 11-3. Therefore, regardless of whether the first display area 11-1 is provided with a reflection adjustment unit ( Figure 13 (Assuming that the reflection adjustment unit is not set in the first display area), at this time, more light will pass through the first display area 11-2 and be reflected by the reflective structure (such as the pixel circuit) in the first display area 11-1. Therefore, the reflectivity of the first display area 11-1 is greater than the reflectivity of the third display area 11-3. In this way, the reflectivity among the second display area 11-2, the third display area 11-3 and the first display area 11-1 can be ensured to gradually increase, that is, along the first direction, the reflectivity of the display panel gradually increases. In this way, the reflectivity difference between the first display area 11-1 and the second display area 11-2 can be reduced, and the boundary between the first display area 11-1 and the second display area 11-2 can be blurred, thereby avoiding display differences caused by large differences in reflectivity in different areas and the problem that the first display area 11-1 is obviously visible when not in the display state, thereby improving the display effect of the display panel and the user experience.

[0089] As another possible implementation, Figure 14 yes Figure 8 Another cross-sectional structural diagram of the display panel provided along the cross-sectional line D-D' is provided, combined with Figure 8 and Figure 14As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, a second color reflection adjustment unit 132 and a third color reflection adjustment unit 133; the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the third color reflection adjustment unit 133, and the reflectivity of the third color reflection adjustment unit 133 is less than the reflectivity of the second color reflection adjustment unit 132; the first color reflection adjustment unit 131 and the third color reflection adjustment unit 133 cover the shading unit 121 on the side of the third display area 11-3 close to the second display area 11-2, and the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133 cover the shading unit 121 on the side of the third display area 11-3 close to the first display area 11-1.

[0090] Specific, combined Figure 8 and Figure 14 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, a second color reflection adjustment unit 132 and a third color reflection adjustment unit 133. Since the reflectivities of the first color reflection adjustment unit 131, the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133 are all lower than the reflectivity of the shading unit 121, and the first reflection adjustment unit 131, the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133 all cover the shading unit 121 located in the third display area 11-3, the luminous flux of the external ambient light reflected on the surface of the third display area 11-3 can be reduced, thereby reducing the light interference of the external ambient light in the third display area 11-3 on the light output of the display panel 10.

[0091] Furthermore, since the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the third color reflection adjustment unit 133, and the reflectivity of the third color reflection adjustment unit 133 is less than the reflectivity of the second color reflection adjustment unit 132, the first color reflection adjustment unit 131 and the third color reflection adjustment unit 133 are set to cover the shading unit 121 on the side of the third display area 11-3 close to the second display area 11-2, and the second color reflection adjustment unit 132 and the third color reflection adjustment unit 133 cover the shading unit 121 on the side of the third display area 11-3 close to the first display area 11-1, which can ensure that the reflectivity in the third display area 11-3 gradually increases along the first direction, that is, the third display area 11-3 gradually increases. The reflectivity of the display area 11-3 on the side close to the second display area 11-2 is smaller and is close to the reflectivity in the second display area 11-2. The reflectivity of the third display area 11-3 on the side close to the first display area 11-1 is larger and is close to the reflectivity in the first display area 11-1. This ensures that the reflectivity of the display panel gradually increases along the first direction, thereby reducing the reflectivity difference between the first display area 11-1 and the second display area 11-2, blurring the boundary between the first display area 11-1 and the second display area 11-2, avoiding display differences caused by large differences in reflectivity in different areas and the problem that the first display area 11-1 is obviously visible when not in display state, thereby improving the display effect of the display panel and user experience.

[0092] It should be noted that the above embodiment is described using the reflectivity gradient in the third display area as an example, i.e., the reflectivity is lower on the side closer to the second display area and higher on the side closer to the first display area. It is understandable that the coverage area of ​​the first color reflective unit in the third display area can also be gradually reduced along the first direction (for specific implementation, see the above embodiment description), and / or the coverage area of ​​the second color reflective unit in the third display area can be gradually increased (for specific implementation, see the above embodiment description), to achieve a gradual increase in the reflectivity of the third display area along the first direction, thereby ensuring a gradual increase in the reflectivity between the second display area, the third display area, and the first display area. That is, the reflectivity of the display panel gradually increases along the first direction, thereby reducing the reflectivity difference between the first display area and the second display area, blurring the boundary between the first display area and the second display area, and improving the display effect of the display panel and the user experience.

[0093] In summary, the above embodiment adds a third display area between the first display area and the second display area, and at the same time sets the reflectivity of the third display area between the reflectivity of the first display area and the reflectivity of the second display area, that is, the reflectivity of the third display area is less than the reflectivity of the first display area and greater than the reflectivity of the second display area. In this way, it is ensured that along the first direction, the reflectivity of the display panel gradually increases, the reflectivity difference between the first display area and the second display area is reduced, the boundary between the first display area and the second display area is blurred, and the display effect of the display panel and the user experience are improved. Furthermore, the reflectivity of the third display area is set to be less than the reflectivity of the first display area and greater than the reflectivity of the second display area. The reflectivity of the third display area can be set to remain unchanged as described in the above embodiment, or the reflectivity of the third display area can be set to change gradually as described in the embodiment, that is, along the first direction, the reflectivity of the third display area gradually increases. The above multiple real-time methods can all ensure that the reflectivity of the display panel gradually increases along the first direction.

[0094] Based on the above embodiments, Figure 15 yes Figure 8 Another cross-sectional structural diagram of the display panel provided along the cross-sectional line EE' is shown in FIG. Figure 8 and Figure 15 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit (not shown in the figure), a second color reflection adjustment unit 132 and a third color reflection adjustment unit (not shown in the figure); the reflectivity of the first color reflection adjustment unit is less than the reflectivity of the third color reflection adjustment unit, and the reflectivity of the third color reflection adjustment unit is less than the reflectivity of the second color reflection adjustment unit 132; the second color reflection adjustment unit 132 covers the first display area.

[0095] Specifically, the second color reflection adjustment unit 132 can be a green reflection adjustment unit. Since the photosensitive element (such as the fingerprint recognition element) arranged corresponding to the photosensitive area is more sensitive to green light, the second color reflection adjustment unit 132 is set to cover the first display area, that is, the second color reflection adjustment unit 132 covers the photosensitive area. In this way, it can be ensured that when the light passing through the photosensitive area is incident on the photosensitive element, the sensitivity of the photosensitive element can be guaranteed to be high.

[0096] Furthermore, since the reflectivity of the second color reflection adjustment unit 132 is lower than the reflectivity of the shading unit, regardless of whether the shading unit is set in the first display area, the reflectivity of the first display area can be reduced by setting the second color reflection adjustment unit 132 to cover the first display area, thereby reducing the reflectivity difference between the first display area and other display areas, blurring the boundary between the first display area and the second display area, and improving the display effect of the display panel and the user experience.

[0097] Based on the above embodiments, Figure 16is a structural diagram of a second display area provided by an embodiment of the present invention, Figure 17 yes Figure 16 A schematic structural diagram of the second display area along the section line FF' is provided. Figure 18 is a structural diagram of a third display area provided by an embodiment of the present invention, Figure 19 yes Figure 18 A schematic cross-sectional structure diagram of the third display area along the section line G-G' is provided, Figure 20 is a structural diagram of a first display area provided by an embodiment of the present invention, Figure 21 yes Figure 20 The schematic diagram of the cross-sectional structure of the first display area along the section line H-H' is provided, combined with Figures 16-21 As shown, the display panel also includes a color filter layer 14 located on the light-emitting side of the light-emitting element 111. The color filter layer 14 includes a plurality of color filter units 141. Along the thickness direction of the display panel (the X direction as shown in the figure), the color filter unit 141 at least partially overlaps with the limited area of ​​the shading unit 121; the reflection adjustment unit 13 is arranged on the same layer as the color filter unit 141.

[0098] Specifically, the display panel provided by the embodiment of the present invention may further include a color filter layer 14 located on the light-emitting side of the light-emitting element 111. The color filter layer 14 includes a plurality of color filter units 141, such as a red color filter unit 141-R, a green color filter unit 141-G, and a blue color filter unit 141-B. Along the thickness direction of the display panel, the color filter units 141 at least partially overlap with the area defined by the light-shielding unit 121, that is, the color filter units 141 at least partially overlap with the light-emitting element. In this way, the color filter units 141 of different colors can filter the light emitted by the light-emitting element 111 to achieve the color display function of the display panel.

[0099] Furthermore, the display panel in the prior art generally sets a polarizer on the light-emitting side of the light-emitting element, and absorbs the external ambient light through the polarizer, thereby increasing the proportion of the display panel's own light output, thereby achieving normal display of the display panel. However, since the polarizer also absorbs the normal light output of the display panel, and the polarizer is relatively thick and not easy to bend, setting the polarizer will reduce the normal light output of the display panel, and cause the overall thickness of the display panel to be relatively large and unable to realize a bendable or curved display panel. In the technical solution of the embodiment of the present invention, by setting a color filter layer and a light-shielding layer on the light-emitting side of the light-emitting element 111, the color filter layer and the light-shielding layer are used to filter or absorb the external ambient light, thereby reducing the light incident on the inside of the display panel, that is, the reflection of the external ambient light by the reflective layer (such as the pixel circuit or other metal reflective layer) inside the display panel can be reduced, reducing the reflection of the external ambient light by the display panel, increasing the proportion of the display panel's own light output, and improving the display effect of the display panel. Therefore, the scheme of the light-shielding layer and the color filter layer can replace the polarizer, and the overall thickness of the light-shielding layer and the color filter layer is relatively small and easy to bend. Therefore, in the embodiment of the present invention, by arranging the color filter layer and the light-shielding layer on the light-emitting side of the light-emitting element, it is ensured that the interference of the external ambient light on the normal light output of the display panel can be reduced, and at the same time, the overall thickness of the display panel is relatively small, which makes it easy to realize a bendable or curved display panel.

[0100] Furthermore, the color filter unit 141 has a relatively low reflectivity, so the reflection adjustment unit 13 can be set on the same layer as the color filter unit 141, that is, the reflection adjustment unit 13 and the color filter unit 141 are made of the same material and prepared by the same process. In this way, on the one hand, the setting method of the reflection adjustment unit 13 is simple, and on the other hand, the reflection adjustment unit 13 and the color filter unit 141 are set on the same layer to ensure that the display panel film layer structure is simple, which is conducive to realizing a thin design of the display panel.

[0101] Furthermore, the display panel provided by the embodiment of the present invention may also include an encapsulation layer (not shown). The encapsulation layer is disposed between the light-emitting element and the color filter layer to encapsulate and protect the light-emitting element, preventing moisture or oxygen from entering the light-emitting element and corroding the light-emitting element, thereby ensuring normal operation of the light-emitting element. Specifically, the encapsulation layer may be a thin film encapsulation layer, such as TFE. The color filter layer is formed on the thin film encapsulation layer to form a "CFOT" structure.

[0102] Specifically, such as Figure 16 and Figure 17 As shown, in the second display area 11-2, the first color reflection adjustment unit 131 can be provided in the same layer as the red color filter unit 141-R; Figure 18 and Figure 19 As shown, in the third display area 11-3, the third color reflection adjustment unit 133 can be provided in the same layer as the blue color filter unit 141-B; Figure 20and Figure 21 As shown, in the first display area 11-1, the second color reflection adjustment unit 132 can be disposed in the same layer as the green filter unit 141-B. This ensures that the arrangement of the reflection adjustment unit 132 is simple, and that the reflectivity of the display panel gradually increases along the first direction by combining the reflective properties of the different color filter units 141.

[0103] It should be noted that Figure 20 and Figure 21 The first display area 11-1 is not provided with a light shielding unit as an example for description. Figure 16 、 Figure 18 and Figure 20 In the embodiment, the reflection adjustment unit and the shading unit or the substrate are staggered, while in an actual display panel, the reflection adjustment unit and the shading unit or the substrate are not staggered.

[0104] Based on the above embodiments, continue to refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the reflection adjustment unit 13 includes a first color reflection adjustment unit 131, a second color reflection adjustment unit 132 and a third color reflection adjustment unit 133; the reflectivity of the first color reflection adjustment unit 131 is less than the reflectivity of the third color reflection adjustment unit 133, and the reflectivity of the third color reflection adjustment unit 133 is less than the reflectivity of the second color reflection adjustment unit 132; the first color reflection adjustment unit 131 includes a first adjustment surface 1311 close to the light emitting element 111 and a second adjustment surface 1312 away from the light emitting element 111, and the second color reflection adjustment unit 13 The third color reflection adjustment unit 133 includes a third adjustment surface 1321 on a side close to the light-emitting element 111 and a fourth adjustment surface 1322 on a side away from the light-emitting element 111. The third color reflection adjustment unit 133 includes a fifth adjustment surface 1331 on a side close to the light-emitting element 111 and a sixth adjustment surface 1332 on a side away from the light-emitting element 111. Along the thickness direction of the display panel (the X direction shown in the figure), the first adjustment surface 1311 covers the second adjustment surface 1312, the fourth adjustment surface 1322 covers the third adjustment surface 1321, and the fifth adjustment surface 1331 covers the sixth adjustment surface 1332.

[0105] For example, Figure 9As shown, the first color reflection adjustment unit 131 includes a first adjustment surface 1311 on the side close to the light emitting element 111 and a second adjustment surface 1312 on the side away from the light emitting element 111, wherein along the thickness direction of the display panel (the X direction shown in the figure), the first adjustment surface 1311 covers the second adjustment surface 1312, that is, the first color reflection adjustment unit 131 is a structure approximately in the shape of a "normal trapezoid", which ensures that the manufacturing process of the first color reflection adjustment unit 131 is simple and the structural feasibility is high. Figure 10 As shown, the third color reflection adjustment unit 133 includes a fifth adjustment surface 1331 on the side close to the light emitting element 111 and a sixth adjustment surface 1332 on the side away from the light emitting element 111. Along the thickness direction of the display panel (the X direction shown in the figure), the fifth adjustment surface 1331 covers the sixth adjustment surface 1332, that is, the third color reflection adjustment unit 133 is a structure approximately in the shape of a "normal trapezoid", which ensures that the preparation process of the third color reflection adjustment unit 133 is simple and the structural feasibility is high. Figure 11 As shown, the second color reflection adjustment unit 132 includes a third adjustment surface 1321 on the side close to the light-emitting element 111 and a fourth adjustment surface 1322 on the side away from the light-emitting element 111. Along the thickness direction of the display panel (the X direction as shown in the figure), the fourth adjustment surface 1322 covers the third adjustment surface 1321, that is, the second color reflection adjustment unit 132 has an approximately "inverted trapezoidal" structure.
