[0031] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0032] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0033] In the display panel that adopts the Camera Under Panel (CUP) technology, the display panel can be divided into a light-transmitting area, a transition area and a conventional display area, wherein the light-transmitting area is the area where the under-screen camera is located, and the conventional display area is the other areas in the display screen except the light-transmitting area and the transition area.

[0034] In the related art, the display consistency of the display panel is poor, which affects the user experience.

[0035] Based on the above technical problems, the inventors have discovered that by making the refractive indices of the planarization layer and the light adjustment layer different, the planarization layer is in contact with the light adjustment layer at least in the transition zone, thereby increasing the reflectivity of the transition zone and reducing the reflectivity difference among the light-transmitting zone, the transition zone and the conventional display zone, thereby reducing the display difference among the light-transmitting zone and the conventional display zone, thereby improving the display consistency of the display panel.

[0036] Based on this, the inventors further studied the technical solution of the embodiment of the present application. Specifically, the embodiment of the present application provides a display panel, the display panel includes a light-transmitting area, a transition area and a conventional display area; the transition area is located between the light-transmitting area and the conventional display area; at least part of the transition area is arranged around the light-transmitting area; the display panel includes a substrate, a light-emitting layer, a filter layer, a light adjustment layer and a planarization layer, the light-emitting layer is arranged on one side of the substrate, the light-emitting layer includes a plurality of first light-emitting units arranged in the transition area; the filter layer is arranged on a side of the light-emitting layer away from the substrate; the filter layer includes a plurality of first filter units arranged corresponding to the plurality of first light-emitting units; the light adjustment layer is arranged on a side of the light-emitting layer away from the substrate; the planarization layer is arranged on a side of the light-emitting layer away from the substrate; the planarization layer is arranged on a side of the filter layer and the light adjustment layer away from the substrate; wherein the refractive index of the planarization layer is different from that of the light adjustment layer, and the planarization layer is in contact with the light adjustment layer at least in the transition area.

[0037] By adopting the above technical solution, the light adjustment layer is arranged on the side of the light-emitting layer away from the substrate, and the flattening layer is arranged on the side of the filter layer and the light adjustment layer away from the substrate, so that the refractive index of the flattening layer and the light adjustment layer is different, and the flattening layer is in contact with the light adjustment layer at least in the transition zone. In this way, the reflectivity of the transition zone can be improved, and the difference in reflectivity among the light-transmitting zone, the transition zone and the conventional display zone can be reduced, thereby reducing the display difference among the transition zone, the light-transmitting zone and the conventional display zone, and improving the display consistency of the display panel.

[0038] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] See also Figures 1 to 3As shown, the embodiment of the present application provides a display panel 10, the display panel 10 includes a light-transmitting area 10a, a transition area 10b and a conventional display area 10c; the transition area 10b is located between the light-transmitting area 10a and the conventional display area 10c; at least part of the transition area 10b is arranged around the light-transmitting area 10a; the display panel 10 includes a substrate 11, a light-emitting layer 12, a filter layer 13, a light-adjusting layer and a planarization layer 14; the light-emitting layer 12 is arranged on one side of the substrate 11, and the light-emitting layer 12 includes a light-transmitting layer 10b arranged on the transition area 10b The light-emitting layer 12 comprises a plurality of first light-emitting units 121; the filter layer 13 is arranged on a side of the light-emitting layer 12 away from the substrate 11; the filter layer 13 includes a plurality of first filter units 131 arranged corresponding to the plurality of first light-emitting units 121; the light-adjusting layer is arranged on a side of the light-emitting layer 12 away from the substrate 11; the planarization layer 14 is arranged on a side of the filter layer 13 and the light-adjusting layer away from the substrate 11; wherein the planarization layer 14 has a different refractive index from the light-adjusting layer, and the planarization layer 14 is in contact with the light-adjusting layer at least in the transition region 10b.

[0041] Specifically, the display panel 10 may be various types of display panels 10 , such as an OLED display panel, a Micro-LED display panel, a Mini-LED display panel, etc. The display panel 10 may be a flexible display panel.

[0042] See also Figures 2 to 4 As shown, the substrate 11 may be an array substrate, which includes a substrate 111 and a driving circuit layer 112 disposed on the substrate, wherein the driving circuit layer 112 includes a pixel driving circuit. The driving circuit layer 112 may be located in the conventional display area 10c and the transition area 10b.

[0043] See also Figures 2 to 5 As shown, the display panel 10 includes a pixel defining layer 17, which can be disposed on one side of the substrate 11. A plurality of pixel openings 17a are provided on the pixel defining layer 17, and the first light emitting unit 121 is at least partially disposed in the corresponding pixel openings 17a. The pixel defining layer 17 can be a black pixel defining layer, so that the overall reflectivity of the display panel 10 can be reduced and the display effect of the display panel 10 can be improved.

[0044] See also Figure 5 As shown, the light-transmitting area 10a, also called the CUP area, can realize the light-emitting display function; it can also realize the function of optical signal transmission, such as at least one of the functions of taking pictures and biometric identification. The light-transmitting area 10a can be used to set optical functional elements. For example, the light-transmitting area 10a can be set with a camera, a fingerprint identification structure, and other devices integrated with optical sensors. To ensure that enough light reaches the optical functional elements, the light-transmitting area 10a has a high transmittance, which also makes the reflectivity of the light-transmitting area 10a larger.

[0045] See also Figure 4As shown, the conventional display area 10c is the other area of ​​the display panel 10 except the light-transmitting area 10a and the transition area 10b. The conventional display area 10c is the conventional display area of ​​the display panel 10. To ensure the display effect of the display panel 10, the reflectivity of the conventional display area 10c is relatively large.

[0046] See also Figure 2 and Figure 3 As shown, the transition area 10b is at least partially arranged around the light-transmitting area 10a, and the transition area 10b can realize the light-emitting display function. The transition area 10b can be used for wiring. For example, the transition area 10b can be used to set a pixel driving circuit, and the pixel driving circuit can be electrically connected to the light-emitting element of the light-transmitting area 10a. In this way, it is not necessary to set a pixel driving circuit in the light-transmitting area 10a to improve the transmittance of the light-transmitting area 10a. Since the transition area 10b occupies a small area in the display panel 10, the aperture ratio of the transition area 10b is small, so that the reflectivity of the transition area 10b is small. In the present application, the refractive index of the planarization layer 14 and the light adjustment layer is different, and the planarization layer 14 is in contact with the light adjustment layer at least in the transition area 10b. In this way, the reflectivity of the transition area 10b can be improved, and the reflectivity difference between the light-transmitting area 10a, the transition area 10b and the conventional display area 10c can be reduced, so that the display difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c can be reduced, thereby improving the display consistency of the display panel 10.

[0047] The filter layer 13 is arranged on the side of the light-emitting layer 12 away from the substrate 11. The filter layer 13 is used to replace the polarizer to achieve the effect of reducing reflection, ensure the display effect of the flexible display panel 10, and improve the bendability of the flexible display panel 10. The thickness of the filter layer 13 is much smaller than the thickness of the polarizer, thereby reducing the thickness of the display panel 10.

[0048] See also Figure 2 and Figure 3As shown, the plurality of first light-emitting units 121 may include a red light-emitting unit, a green light-emitting unit and a blue light-emitting unit; the plurality of first filter units 131 may include a red filter unit, a green filter unit and a blue filter unit. Specifically, the red filter unit may be arranged corresponding to the red light-emitting unit, the green filter unit may be arranged corresponding to the green light-emitting unit, and the blue filter unit may be arranged corresponding to the blue light-emitting unit. Taking the red light-emitting unit as an example, after the red light emitted by the red light-emitting unit passes through the red filter unit, due to the filtering effect of the red filter unit, the light that deviates more from the red spectrum can be filtered out, so that the purity of the red light passing through the red filter unit is improved. In this way, the color purity of the display panel 10 can be improved, and the display effect of the display panel 10 can be improved. In addition, when external ambient light is incident on the first filter unit 131, light in the ambient light that is inconsistent with the color of the first filter unit 131 is filtered and cannot further enter the display panel 10, thereby effectively reducing the amount of ambient light reflected by the metal layer in the display panel 10, thereby reducing the reflection of ambient light, improving the contrast of the display panel 10, and improving the display quality of the display panel 10.

[0049] See also Figure 2 and Figure 3 As shown, the planarization layer 14 is disposed on the side of the filter layer 13 and the light adjustment layer away from the substrate 11, and the planarization layer 14 can prevent dust and water vapor from entering the interior of the display panel 10, and can also maintain the surface cleanliness of the display panel 10. On the other hand, the planarization layer 14 can be a whole film layer to improve the flatness of the side of the filter layer 13 away from the substrate 11, so as to facilitate the subsequent film layer manufacturing.

[0050] In summary, the display panel 10 provided in the embodiment of the present application, by setting the light adjustment layer on the side of the light-emitting layer 12 away from the substrate 11, and setting the planarization layer 14 on the side of the filter layer 13 and the light adjustment layer away from the substrate 11, the refractive index of the planarization layer 14 and the light adjustment layer is different, and the planarization layer 14 is in contact with the light adjustment layer at least in the transition zone 10b. In this way, the reflectivity of the transition zone 10b can be improved, and the reflectivity difference among the light-transmitting zone 10a, the transition zone 10b and the conventional display zone 10c can be reduced, thereby reducing the display difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c, and improving the display consistency of the display panel 10.

[0051] See also Figure 2As shown, in some embodiments, the display panel 10 includes a first light shading structure 151 located in the transition zone 10b, and the first light shading structure 151 is arranged on the side of the light-emitting layer 12 away from the substrate 11; a plurality of first openings 151a are opened on the first light shading structure 151, and a plurality of first filter units 131 are correspondingly arranged in the plurality of first openings 151a; the first light shading structure 151 is reused as a light adjustment layer; the absolute value of the difference between the refractive index of the first light shading structure 151 and the refractive index of the planarization layer 14 is greater than 0.1; the planarization layer 14 is in contact with the surface of the first light shading structure 151 away from the light-emitting layer 12.

[0052] Therefore, by locating the first light shading structure 151 in the transition zone 10b, the first light shading structure 151 is disposed on the side of the light emitting layer 12 away from the substrate 11, a plurality of first openings 151a are opened on the first light shading structure 151, and a plurality of first filter units 131 are correspondingly disposed in the plurality of first openings 151a. In this way, the first light shading structure 151 can separate different first filter units 131, thereby reducing the crosstalk between the light emitted by the first filter units 131 of different colors. The absolute value of the difference between the refractive index of the first shading structure 151 and the refractive index of the planarization layer 14 is greater than 0.1, that is, the difference between the first shading structure 151 and the planarization layer 14 is relatively large. The first shading structure 151 is reused as a light adjustment layer and contacts the planarization layer 14. In this way, on the one hand, the reflectivity of the transition zone 10b can be effectively improved, and the reflectivity difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c can be reduced, thereby improving the display consistency of the display panel 10. On the other hand, by utilizing the refractive index difference between the first shading structure 151 and the planarization layer 14, the first shading structure 151 is reused as a light adjustment layer without the need to specially set up a separate light adjustment layer, which is beneficial to the thinning design of the display panel 10.

[0053] Optionally, the first light shielding structure 151 is a black matrix (BM) or a black light shielding material.

[0054] In some embodiments, the contact area between the planarization layer 14 and the first light shielding structure 151 away from the light emitting layer 12 is L, the area of ​​the first light shielding structure 151 away from the light emitting layer 12 is S, and L / S is 40%-85%.

[0055] Therefore, by setting the ratio of the contact area L between the planarization layer 14 and the first shading structure 151 to the area S of the surface of the first shading structure 151 away from the light-emitting layer 12 within the above-mentioned appropriate range, the reflectivity of the transition zone 10b can be effectively improved, so that the reflectivity of the transition zone 10b is close to the reflectivity of the conventional display zone 10c, thereby effectively reducing the display difference between the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c, and improving the display consistency of the display panel 10.

[0056] See also Figure 3 As shown, in some embodiments, the display panel 10 includes an inorganic packaging layer 16 and a first light shading structure 151; the inorganic packaging layer 16 is arranged between the filter layer 13 and the light-emitting layer 12; the inorganic packaging layer 16 is reused as a light adjustment layer; the first light shading structure 151 is located in the transition zone 10b; the first light shading structure 151 is arranged on the side of the inorganic packaging layer 16 away from the substrate 11; a plurality of first openings 151a are opened on the first light shading structure 151, and a plurality of first filter units 131 are correspondingly arranged in the plurality of first openings 151a; the absolute value of the difference between the refractive index of the first light shading structure 151 and the refractive index of the planarization layer 14 is less than 0.1, and a through hole 151b is opened on the first light shading structure 151, and the planarization layer 14 is in contact with the inorganic packaging layer 16 through the through hole 151b.

[0057] The inorganic encapsulation layer 16 is generally a film layer with a high refractive index, and the refractive index of the inorganic encapsulation layer 16 may be greater than the refractive index of the planarization layer 14. In this embodiment, the inorganic encapsulation layer 16 is disposed between the filter layer 13 and the light-emitting layer 12. On the one hand, the inorganic encapsulation layer 16 can encapsulate the light-emitting layer 12, thereby reducing the probability of failure of the light-emitting layer 12 and ensuring the normal display of the display panel 10. On the other hand, the absolute value of the difference between the refractive index of the first shading structure 151 and the refractive index of the planarization layer 14 is less than 0.1, that is, the difference between the refractive index of the first shading structure 151 and the refractive index of the planarization layer 14 is small, the inorganic encapsulation layer 16 is reused as a light adjustment layer, and a through hole 151b is opened on the first shading structure 151, and the planarization layer 14 is in contact with the inorganic encapsulation layer 16 through the through hole 151b. By utilizing the refractive index difference between the planarization layer 14 and the inorganic encapsulation layer 16, the reflectivity of the transition zone 10b can be effectively improved, and the reflectivity difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c can be reduced, thereby reducing the display difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c, thereby improving the display consistency of the display panel 10.

[0058] See also Figure 3 As shown, optionally, the display panel 10 may include multiple layers of inorganic encapsulation layers 16 and organic encapsulation layers 162, and at least one layer of organic encapsulation layer 162 may be provided between adjacent inorganic encapsulation layers 16. Specifically, the display panel 10 may include a first inorganic encapsulation layer 161, an organic encapsulation layer 162, and a second inorganic encapsulation layer 163, the first inorganic encapsulation layer 161 is provided on a side of the light-emitting layer 12 away from the substrate 11, the organic encapsulation layer 162 is provided on a side of the first inorganic encapsulation layer 161 away from the substrate 11, the second inorganic encapsulation layer 163 is provided on a side of the organic encapsulation layer 162 away from the substrate 11, the filter layer 13 and the first light shielding structure 151 are provided on a side of the second inorganic encapsulation layer 163 away from the substrate 11, and the second inorganic encapsulation layer 163 may be reused as a light adjustment layer.

[0059] Optionally, the material of the inorganic encapsulation layer 16 includes at least one of silicon nitride and silicon oxynitride.

[0060] In some embodiments, the ratio of the orthographic projection area of ​​the through hole 151 b on the substrate 11 to the orthographic projection area of ​​the first light shielding structure 151 on the substrate 11 is 2% to 10%.

[0061] Therefore, by setting the ratio of the orthographic projection area of ​​the through hole 151b on the substrate 11 to the orthographic projection area of ​​the first shading structure 151 on the substrate 11 within the above-mentioned appropriate range, the reflectivity of the transition zone 10b can be effectively improved, so that the reflectivity of the transition zone 10b is close to the reflectivity of the conventional display zone 10c, thereby effectively reducing the display difference between the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c, and improving the display consistency of the display panel 10.

[0062] In some embodiments, the refractive index of the first light shielding structure 151 is 1.5-2.0; the refractive index of the planarization layer 14 is 1.5-1.6.

[0063] In some embodiments, the refractive index of the inorganic encapsulation layer 16 is 1.8-2.0.

[0064] See also Figure 2 and Figure 3 As shown, in some embodiments, at least one first filter unit 131 extends to a side of the first light shielding structure 151 away from the substrate 11 .

[0065] In other words, see Figure 2 and Figure 3 As shown, the orthographic projection of the filter layer 13 on the substrate 11 overlaps with the orthographic projection of the first light shielding structure 151 on the substrate 11 .

[0066] In this way, the reflectivity of the transition zone 10b can be easily adjusted, and the reflectivity difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c can be reduced, thereby reducing the display difference among the transition zone 10b, the light-transmitting zone 10a and the conventional display zone 10c and improving the display consistency of the display panel 10.

[0067] See also Figure 4As shown, in some embodiments, the light-emitting layer 12 also includes a plurality of second light-emitting units 122 disposed in the conventional display area 10c; the filter layer 13 also includes a plurality of second filter units 132 disposed corresponding to the plurality of second light-emitting units 122; the display panel 10 also includes a second shading structure 152 located in the conventional display area 10c, the second shading structure 152 is disposed on a side of the light-emitting layer 12 away from the substrate 11, a plurality of second openings 152a are provided on the second shading structure 152, and the plurality of second filter units 132 are correspondingly disposed in the plurality of second openings 152a; at least one second filter unit 132 extends to a side of the second shading structure 152 away from the substrate 11.

[0068] Thus, on the one hand, the second filter unit 132 can filter the light emitted by the second light emitting unit 122 and the ambient light, thereby improving the color purity and contrast of the normal display area 10c of the display panel 10, thereby improving the display effect of the display panel 10; on the other hand, the second light shielding structure 152 can separate different second filter units 132, thereby reducing the crosstalk between the light emitted by the second filter units 132 of different colors, thereby improving the display effect of the display panel 10. In addition, at least one second filter unit 132 extends to the side of the second light shielding structure 152 away from the substrate 11, the second filter unit 132 can filter the ambient light, and the second light shielding structure 152 can absorb the ambient light, so that the reflectivity of the normal display area 10c of the display panel 10 can be reduced, and the reflectivity difference between the transition area 10b, the light-transmitting area 10a and the normal display area 10c can be reduced, thereby reducing the display difference between the transition area 10b, the light-transmitting area 10a and the normal display area 10c, and improving the display consistency of the display panel 10.

[0069] It is understandable that the plurality of second light emitting units 122 may include a red light emitting unit, a green light emitting unit and a blue light emitting unit; the plurality of second filter units 132 may include a red filter unit, a green filter unit and a blue filter unit. Specifically, the red filter unit may be arranged corresponding to the red light emitting unit, the green filter unit may be arranged corresponding to the green light emitting unit, and the blue filter unit may be arranged corresponding to the blue light emitting unit.

[0070] See also Figure 4 As shown, in some embodiments, the orthographic projection of the filter layer 13 on the substrate 11 overlaps with the orthographic projection of the second light shielding structure 152 on the substrate 11 .

[0071] Therefore, the filter layer 13 is used to filter the ambient light, and the second shading structure 152 absorbs the ambient light. In this way, the reflectivity of the conventional display area 10c of the display panel 10 can be effectively reduced, and the reflectivity difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c can be reduced, thereby reducing the display difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c, thereby improving the display consistency of the display panel 10.

[0072] See also Figures 2 to 4 As shown, in some embodiments, the second light shielding structure 152 is disposed in the same layer as the first light shielding structure 151. The second light shielding structure 152 and the first light shielding structure 151 can be manufactured and formed simultaneously, and the second light shielding structure 152 and the first light shielding structure 151 can be made of the same material.

[0073] See also Figure 5 As shown, in some embodiments, the light-emitting layer 12 also includes a plurality of third light-emitting units 123 disposed in the light-transmitting area 10a; the filter layer 13 also includes a plurality of third filter units 133 disposed corresponding to the plurality of third light-emitting units 123; the display panel 10 also includes a third light-shielding structure 153 located in the light-transmitting area 10a, the third light-shielding structure 153 is disposed on a side of the light-emitting layer 12 away from the substrate 11, a third opening 153a and a plurality of fourth openings 153b are provided on the third light-shielding structure 153, and the plurality of third filter units 133 are correspondingly disposed in the plurality of fourth openings 153b; at least one third filter unit 133 extends to a side of the third light-shielding structure 153 away from the substrate 11.

[0074] Therefore, on the one hand, the light emitted by the third light-emitting unit 123 can be filtered through the third filter unit 133, and the ambient light can be filtered, so as to improve the color purity and contrast of the light-transmitting area 10a of the display panel 10, thereby improving the display effect of the display panel 10; on the other hand, the third shading structure 153 can separate different third filter units 133, so as to reduce the crosstalk between the light emitted by the third filter units 133 of different colors, thereby improving the display effect of the display panel 10. In addition, at least one third filter unit 133 extends to the side of the second shading structure 152 away from the substrate 11. The third filter unit 133 can filter ambient light, and the third shading structure 153 can absorb ambient light. In this way, the reflectivity of the light-transmitting area 10a of the display panel 10 can be reduced, and the reflectivity difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c can be reduced, thereby reducing the display difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c, thereby improving the display consistency of the display panel 10.

[0075] It is understandable that the plurality of third light emitting units 123 may include a red light emitting unit, a green light emitting unit and a blue light emitting unit; the plurality of third filter units 133 may include a red filter unit, a green filter unit and a blue filter unit. Specifically, the red filter unit may be arranged corresponding to the red light emitting unit, the green filter unit may be arranged corresponding to the green light emitting unit, and the blue filter unit may be arranged corresponding to the blue light emitting unit.

[0076] It should be noted that, see Figure 5 As shown, the light-transmitting area 10a includes a plurality of light-emitting sub-areas and light-transmitting sub-areas, the third light-emitting unit 123 can be arranged in the light-emitting sub-area, the third opening 153a can be located in the light-transmitting sub-area, and a fifth opening 17b is further provided on the pixel defining layer 17, and the fifth opening 17b can be located in the light-transmitting sub-area. In this way, the transmittance of the light-transmitting area 10a can be guaranteed.

[0077] In some embodiments, see Figure 5 As shown, the orthographic projection of the filter layer 13 on the substrate 11 overlaps with the orthographic projection of the third light shielding structure 153 on the substrate 11 .

[0078] Therefore, the filter layer 13 is used to filter the ambient light, and the third shading structure 153 absorbs the ambient light. In this way, the reflectivity of the light-transmitting area 10a of the display panel 10 can be effectively reduced, and the reflectivity difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c can be reduced, thereby reducing the display difference between the transition area 10b, the light-transmitting area 10a and the conventional display area 10c, thereby improving the display consistency of the display panel 10.

[0079] See also Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the third light shielding structure 153 is disposed in the same layer as the first light shielding structure 151. The third light shielding structure 153 and the first light shielding structure 151 can be manufactured and formed simultaneously, and the third light shielding structure 153 and the first light shielding structure 151 can be made of the same material.
