[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0029] Please refer to Figure 1 In related technologies, a display panel includes a camera area A1, a non-camera area A2, and a transition area A3 located between the camera area A1 and the non-camera area A2. The display panel also includes pixels 1 disposed in the camera area A1, the non-camera area A2, and the transition area A3. To improve the transmittance of the display panel and reduce its power consumption, a color filter layer is disposed within the display panel to achieve anti-reflection. Consequently, a light-shielding layer 2 is formed in the display panel, and in a top view, the light-shielding layer 2 is located between adjacent pixels 1. At the same time, to improve the transmittance within the camera area A1, most of the light-shielding layer 2 within the camera area A1 is removed, leaving a ring-shaped light-shielding layer 2 surrounding the pixels 1. However, most of the light-shielding layer 2 is retained in the transition area A3 and the non-camera area A2, resulting in a large difference in reflectance between the camera area A1 and the non-camera area A2, which seriously affects the display effect of the display panel.

[0030] Please refer to Figure 2 and Figure 3 This application provides a display panel, which includes a first display area 101, a second display area 102, and a transition display area 103 located between the first display area 101 and the second display area 102.

As the area proportion of the first light-shielding part 21 decreases, the reflectivity of the corresponding area can increase accordingly. As a result, the transition display area 103 can form a reflectivity step between the first display area 101 and the second display area 102, so that the reflectivity difference between the first display area 101 and the second display area 102 transitions smoothly, improving the phenomenon of poor display caused by the large reflectivity difference between the first display area 101 and the second display area 102.

[0061] In this embodiment, the area ratio of the first light-shielding part 21 in the first display area 101 is less than or equal to the area ratio of the first light-shielding part 21 in the transition display area 103, and the area ratio of the first light-shielding part 21 in the transition display area 103 is less than the area ratio of the first light-shielding part 21 in the second display area 102. In this embodiment, by differentiating the area ratio of the first light-shielding part 21 in different areas of the color filter layer 20, and as the area ratio of the first light-shielding part 21 decreases, the reflectivity of the corresponding area can be increased accordingly. Thus, the transition display area 103 can form a reflectivity step between the first display area 101 and the second display area 102, so that the reflectivity difference between the first display area 101 and the second display area 102 transitions smoothly, improving the phenomenon of poor display caused by the large reflectivity difference between the first display area 101 and the second display area 102.

[0062] It should be noted that the area ratio of the first light-shielding part 21 in a region can be the ratio of the area of ​​the first light-shielding part 21 to the area of ​​the region; for example, the area ratio of the first light-shielding part 21 in the first display area 101 can be the ratio of the area of ​​the first light-shielding part 21 to the area of ​​the first display area 101; the area ratio of the first light-shielding part 21 in the second display area 102 can be the ratio of the area of ​​the first light-shielding part 21 to the area of ​​the second display area 102; the area ratio of the first light-shielding part 21 in the transition display area 103 can be the ratio of the area of ​​the first light-shielding part 21 to the area of ​​the transition display area 103.

The second light-shielding portion 30 can be stacked with the pixel definition layer 45 and can be used to reduce light crosstalk and reduce the reflection phenomenon of the display panel.

[0065] In some embodiments, the present application embodiments can also meet the light transmittance requirements of different areas by patterning the second light-shielding portion 30.

[0066] For example, the area ratio of the second light-shielding part 30 in the first display area 101 is smaller than the area ratio of the second light-shielding part 30 in the transition display area 103, and the area ratio of the second light-shielding part 30 in the first display area 101 is smaller than the area ratio of the second light-shielding part 30 in the second display area 102.

[0069] In one specific embodiment of this application, please refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In the first display area 101, in a top view, the first light-shielding part 21 is arranged in a ring around the sub-pixel 10; in the transition display area 103, in a top view, at least part of the first light-shielding part 21 is arranged in a ring around the sub-pixel 10; in the second display area 102, in a top view, the first light-shielding part 21 has holes corresponding to the sub-pixel 10 and multiple holes for light transmission, and does not form multiple isolated rings as in the first display area 101 and the transition display area 103.

[0070] It is understood that in related technologies, the first light-shielding part 21 and the second light-shielding part 30 in the transition display area 103 are both arranged around the sub-pixel 10 and are arranged continuously, rather than in isolated multiple forms, so as to achieve better light-shielding and anti-reflection effects. However, in this embodiment, by making at least a portion of the first light-shielding part 21 in the transition display area 103 arranged in a ring around the sub-pixel 10, the area ratio of the first light-shielding part 21 in the transition display area 103 is reduced, which can increase the reflectivity in the transition display area 103 to a certain extent. This makes the transition display area 103 form a reflectivity transition region between the first display area 101 and the second display area 102, improving the phenomenon of poor display caused by the large difference in reflectivity between the first display area 101 and the second display area 102.

[0071] In this embodiment, within the transition display area 103, the first light-shielding portion 21 is arranged in a ring around the sub-pixel 10.

[0072] In some embodiments, a filter hole 211 and a third opening 214 are formed in the first light-shielding part 21 within the second display area 102, and the third opening 214 is spaced apart from the filter hole 211; wherein, the filter part 22 within the second display area 102 is disposed within the filter hole 211; the third opening 214 can be a light-transmitting hole provided within the second display area 102 for a functional sensor below the display panel, so as to increase the amount of light entering the functional sensor.

[0073] Furthermore, in this embodiment, in the first display area 101, the second light-shielding part 30 is also arranged in a ring around the sub-pixel 10; in the transition display area 103, a plurality of first light-transmitting holes are formed in the second light-shielding part 30, and the sub-pixel 10 is disposed in the first light-transmitting holes; in the second display area 102, a plurality of second light-transmitting holes and a plurality of third light-transmitting holes are formed in the second light-shielding part 30, the sub-pixel 10 is disposed in the second light-transmitting holes, and the area of ​​the third light-transmitting hole is smaller than the area of ​​the second light-transmitting hole.

[0074] The third light-transmitting hole and the third opening 214 are aligned along the thickness direction of the display panel to effectively provide light-transmitting holes for the functional sensors below the display panel, thereby increasing the amount of light entering the functional sensors.

[0075] Furthermore, the array substrate 41 includes signal traces disposed within the transition display area 103, and the second light-shielding portion 30 at least partially overlaps with the signal traces along the thickness direction of the display panel. It should be noted that, in this embodiment, the first light-shielding portion 21 within the transition display area 103 is partially removed, so that the first light-shielding portion 21 is disposed in a ring around the sub-pixel 10. At the same time, this embodiment retains the second light-shielding portion 30 within the transition display area 103. That is, within the transition display area 103, the second light-shielding portion 30 only forms a first light-transmitting hole at the position corresponding to the sub-pixel 10, while the second light-shielding portion 30 is continuously disposed at other positions to provide an effective shielding effect to block the signal traces below.

[0076] It is understandable that in related technologies, the first light-shielding part 21 and the second light-shielding part 30 in the transition display area 103 only make openings at the position of sub-pixel 10, while other positions are retained; however, in the embodiment of this application, the first light-shielding part 21 in the transition display area 103 only retains the annular structure around the sub-pixel 10, while other areas are removed, and the second light-shielding part 30 in the transition display area 103 only makes openings at the position of sub-pixel 10, while other positions are retained; thus, on the one hand, the number and thickness of the light-shielding parts stacked along the thickness direction of the display panel in the transition display area 103 are reduced, thereby increasing the reflectivity in the transition display area 103 compared to related technologies; on the other hand, the retention of the second light-shielding part 30 effectively blocks the signal traces, avoiding the reflection of the signal traces.

[0077] In some embodiments, the signal traces may include scan lines connected to the gate driving circuit and data lines connected to the driving chip; wherein, the scan lines extend along a first direction X, and in order to avoid the first display area 101, they are wound around the periphery of the first display area 101 along the extension path, and the wound scan lines are located within the transition display area 103; similarly, the data lines extend along a second direction Y, and in order to avoid the first display area 101 along the extension path, they are wound around the periphery of the first display area 101, and the wound data lines are located within the transition display area 103.

[0078] Furthermore, since the first light-shielding part 21 and the second light-shielding part 30 are both retained in a large area within the second display area 102, the first light-shielding part 21 and the second light-shielding part 30 are both made to have openings at the positions of the sub-pixels 10, and respectively a third opening 214 and a third light-transmitting hole are formed. As a result, the area ratio of the first light-shielding part 21 within the second display area 102 is maximized, and the number and thickness of the light-shielding parts stacked along the thickness direction of the display panel are maximized, thereby maximizing the reflectivity within the second display area 102. Therefore, in this embodiment, the reflectivity of the display panel within the first display area 101 is greater than that within the transition display area 103, and the reflectivity of the display panel within the transition display area 103 is greater than that within the second display area 102. This allows for the formation of a reflectivity gradient among the first display area 101, the second display area 102, and the transition display area 103, improving the display defects caused by the large difference and abrupt change in reflectivity between the first display area 101 and the second display area 102.

[0079] Furthermore, in this embodiment, the first light-shielding part 21 in the transition display area 103 and the first light-shielding part 21 in the second display area 102 are connected around the sub-pixel 10 at the boundary line between the transition display area 103 and the second display area 102.

[0080] In some embodiments, please refer to Figure 2 In the top view, the first light-shielding part 21 forms multiple virtual steps 210 at the boundary line between the transition display area 103 and the second display area 102; that is, the first light-shielding part 21 is in the shape of a step at the boundary line between the transition display area 103 and the second display area 102.

[0081] In some embodiments, a plurality of pixel units 100 are arranged along a first direction X and a second direction Y, and each pixel unit 100 includes at least two sub-pixels 10 with different emission colors.

[0082] The virtual step 210 includes a first side 2101 extending along the first direction X and a second side 2102 extending along the second direction Y. The number of pixel units 100 corresponding to and adjacent to the first side 2101 along the second direction Y is an integer, and the number of pixel units 100 corresponding to and adjacent to the second side 2102 along the first direction X is an integer. It should be noted that in this embodiment, each pixel unit 100 can be regarded as a display unit, and the distribution range of the first light-blocking part 21 in the transition display area 103 and the second display area 102 is different. Therefore, there is a gradient in reflectivity between the two. Thus, in this embodiment, the edge of the virtual step 210 can correspond to the entire pixel unit 100, so as to avoid a pixel unit 100 being divided at the boundary line between the transition display area 103 and the second display area 102, which would affect the display effect of the display panel.

[0083] In another specific embodiment of this application, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 In this embodiment, the first light-shielding part 21 in the transition display area 103 is further patterned in a more refined manner to enhance the reflectivity gradient change of the display panel in the first display area 101 and the second display area 102.

[0084] Specifically, the transition display area 103 includes a first sub-area 1031 disposed between the first display area 101 and the second display area 102, and a second sub-area 1032 disposed between the first sub-area 1031 and the second display area 102; wherein, the area ratio of the first light-shielding part 21 in the first sub-area 1031 is smaller than the area ratio of the first light-shielding part 21 in the second sub-area 1032.

[0085] In some embodiments, in the first sub-region 1031, in a top view, the first light-shielding portion 21 is arranged in a ring around the sub-pixel 10; in the second sub-region 1032, the first light-shielding portion 21 has a plurality of filter holes 211 and at least one first opening 212, the filter portion 22 is disposed in the filter holes 211, and the first opening 212 is spaced apart from the filter holes 211.

[0086] It is understandable that within the first sub-region 1031, most of the first light-shielding portion 21 can be removed, leaving only the annular first light-shielding portion 21 around the sub-pixel 10; while within the second sub-region 1032, a filter hole 211 and a first opening 212 are formed in the first light-shielding portion 21, and the rest of the first light-shielding portion 21 are retained, so that the area ratio of the first light-shielding portion 21 in the second sub-region 1032 is greater than the area ratio of the first light-shielding portion 21 in the first sub-region 1031.

[0087] In some embodiments, in a top view, the edge profile of the first light-shielding portion 21 at the boundary line between the first sub-region 1031 and the second sub-region 1032 is serrated, wavy, or arc-shaped.

[0088] Furthermore, in some embodiments, the transition display area 103 further includes a third sub-area 1033 disposed between the second sub-area 1032 and the second display area 102; the first light-shielding part 21 has a plurality of filter holes 211 and at least one second opening 213 formed therein, the filter part 22 is disposed in the filter holes 211, the second opening 213 is disposed at intervals from the filter holes 211, and the area of ​​the second opening 213 is smaller than the area of ​​the first opening 212.

[0089] It is understandable that in the third sub-region 1033, the first light-shielding part 21 has a filter hole 211 and a second opening 213, and the rest of the first light-shielding parts 21 are retained; however, by making the area of ​​the second opening 213 smaller than the area of ​​the first opening 212, the area ratio of the first light-shielding part 21 in the third sub-region 1033 is made smaller than the area ratio of the first light-shielding part 21 in the second sub-region 1032.

[0090] In other embodiments of this application, the area of ​​the first opening 212 may be equal to the area of ​​the second opening 213. However, the number of first openings 212 in the second sub-region 1032 is greater than the number of second openings 213 in the third sub-region 1033, so that the total area of ​​the first openings 212 in the second sub-region 1032 is greater than the total area of ​​the second openings 213 in the third sub-region 1033, thereby making the area ratio of the first light-shielding part 21 in the third sub-region 1033 less than the area ratio of the first light-shielding part 21 in the second sub-region 1032.

[0091] In some embodiments, the first aperture 212 is disposed between adjacent filter apertures 211, and the second aperture 213 is disposed between adjacent filter apertures 211. Specifically, in the arrangement of sub-pixels 10, since the first column of sub-pixels has two arrangements of first sub-pixels 11 and second sub-pixels 12, while the second column of sub-pixels only has one arrangement of third sub-pixels 13, the gap between adjacent third sub-pixels 13 in the second column of sub-pixels 10 is relatively large, which can be used to set the first aperture 212 and the second aperture 213. Therefore, the first aperture 212 is disposed between adjacent third sub-pixels 13 arranged along the second direction Y, and the second aperture 213 is disposed between adjacent third sub-pixels 13 arranged along the second direction Y.

[0092] In some embodiments, a filter hole 211 and a third opening 214 are formed in the first light-shielding part 21 within the second display area 102, and the third opening 214 is spaced apart from the filter hole 211; wherein, the filter part 22 within the second display area 102 is disposed within the filter hole 211; the third opening 214 can be a light-transmitting hole provided within the second display area 102 for a functional sensor below the display panel, so as to increase the amount of light entering the functional sensor.

[0093] Furthermore, in this embodiment, in the first display area 101, the second light-shielding part 30 is also arranged in a ring around the sub-pixel 10; in the transition display area 103, a plurality of first light-transmitting holes are formed in the second light-shielding part 30, and the sub-pixel 10 is disposed in the first light-transmitting holes; in the second display area 102, a plurality of second light-transmitting holes and a plurality of third light-transmitting holes are formed in the second light-shielding part 30, the sub-pixel 10 is disposed in the second light-transmitting holes, and the area of ​​the third light-transmitting hole is smaller than the area of ​​the second light-transmitting hole.

[0094] The third light-transmitting hole and the third opening 214 are aligned along the thickness direction of the display panel to effectively provide light-transmitting holes for the functional sensors below the display panel, thereby increasing the amount of light entering the functional sensors.

[0095] In some embodiments, the area of ​​the third opening 214 is smaller than the area of ​​the second opening 213.

[0096] In other words, in this embodiment, within the transition display area 103, the first light-shielding part 21 is patterned differently in the first sub-area 1031, the second sub-area 1032, and the third sub-area 1033, so that the area ratio of the first light-shielding part 21 decreases sequentially. Specifically, the area ratio of the first light-shielding part 21 in the first sub-area 1031 is greater than that in the second sub-area 1032, and the area ratio of the first light-shielding part 21 in the second sub-area 1032 is greater than that in the third sub-area 1033. This forms two reflectivity steps within the transition display area 103, allowing for a smoother transition of reflectivity between the first display area 101 and the second display area 102, thus improving the phenomenon of abrupt changes in reflectivity that severely affect the display panel's display effect.

[0097] Furthermore, in some embodiments, within the second sub-region 1032, a plurality of first openings 212 are formed in the first light-shielding portion 21, and the area of ​​the first opening 212 near the first sub-region 1031 is larger than the area of ​​the first opening 212 near the third sub-region 1033; furthermore, the area of ​​the first opening 212 can gradually decrease along the direction of the first sub-region 1031 near the third sub-region 1033; thereby making the area ratio of the first light-shielding portion 21 within the second sub-region 1032 show a smoother changing trend, which is more conducive to making the reflectivity between the first display area 101 and the second display area 102 transition more smoothly.

[0098] In some embodiments, within the third sub-region 1033, a plurality of second openings 213 are formed in the first light-shielding portion 21, and the area of ​​the second opening 213 near the second sub-region 1032 is larger than the area of ​​the second opening 213 near the second display area 102; thereby making the area ratio of the first light-shielding portion 21 within the third sub-region 1033 show a smoother trend, which is more conducive to a smoother transition of reflectivity between the first display area 101 and the second display area 102.

[0099] In some embodiments, the length of the first sub-region 1031 along the direction from the first display area 101 to the second display area 102 is greater than or equal to 400 micrometers and less than or equal to 1000 micrometers; the length of the second sub-region 1032 along the direction from the first display area 101 to the second display area 102 is greater than or equal to 400 micrometers and less than or equal to 1000 micrometers; and the length of the third sub-region 1033 along the direction from the first display area 101 to the second display area 102 is greater than or equal to 400 micrometers and less than or equal to 1000 micrometers.

[0100] Furthermore, this application provides comparative examples and Embodiments 1 and 2 to verify the solutions in the embodiments of this application; and the difference is that the distribution of the first light-shielding part 21 in different regions is different in the comparative examples and Embodiments 1 and 2.

[0101] In the comparative example, in the first display area 101, the first light-shielding part 21 is arranged in a ring around the sub-pixel 10; in the transition display area 103, the first light-shielding part 21 only has a filter hole 211 corresponding to the sub-pixel 10; in the second display area 102, the first light-shielding part 21 has a filter hole 211 corresponding to the sub-pixel 10 and a third opening 214.

[0102] In the first display area 101, the second light-shielding part 30 is also arranged in a ring around the sub-pixel 10; in the transition display area 103, a plurality of first light-transmitting holes are formed in the second light-shielding part 30, and the sub-pixel 10 is disposed in the first light-transmitting holes; in the second display area 102, a plurality of second light-transmitting holes and a plurality of third light-transmitting holes are formed in the second light-shielding part 30, and the sub-pixel 10 is disposed in the second light-transmitting holes.

[0103] In Embodiment 1, the first light-shielding part 21 and the second light-shielding part 30 are as follows: Figure 2 The settings are configured as shown in the embodiment.

[0104] In Embodiment 1, the length of the transition display area 103 along the direction from the first display area 101 to the second display area 102 is 500 micrometers.

[0105] In Embodiment 2, the first light-shielding part 21 and the second light-shielding part 30 are as follows: Figure 6 , Figure 7 as well as Figure 8 The settings are configured as shown in the embodiment.

[0106] In Embodiment 2, the length of the first sub-region 1031 along the direction from the first display area 101 to the second display area 102 is 500 micrometers; the length of the second sub-region 1032 along the direction from the first display area 101 to the second display area 102 is 500 micrometers; and the length of the third sub-region 1033 along the direction from the first display area 101 to the second display area 102 is 500 micrometers.

[0107] The reflectance was verified and the data are shown in Table 1 below.

[0108] Table 1

[0109] As can be seen from the reflectance data in Table 1, the reflectance differences in the comparative examples are 14% and -2%, respectively, while the reflectance differences in Example 1 are 3% and 9%, respectively, and the reflectance differences in Example 2 are 3%, 5%, 2%, and 2%, respectively. That is, the reflectance transition in the scheme shown in Example 2 of this application is optimal, while the reflectance transition in the scheme shown in Example 1 is second best. In contrast, the reflectance transition in the scheme shown in the comparative examples is poor, which easily leads to abrupt changes in reflectance, thereby seriously affecting the display effect of the display panel.

[0110] In summary, this embodiment differentiates the area proportion of the first light-shielding part 21 in different regions of the color filter layer 20. Specifically, the area proportion of the first light-shielding part 21 in the first display area 101 is less than or equal to the area proportion of the first light-shielding part 21 in the transition display area 103, and the area proportion of the first light-shielding part 21 in the transition display area 103 is less than the area proportion of the first light-shielding part 21 in the second display area 102. As the area proportion of the first light-shielding part 21 decreases, the reflectivity of the corresponding area can increase accordingly. As a result, the transition display area 103 can form a reflectivity step between the first display area 101 and the second display area 102, so that the reflectivity difference between the first display area 101 and the second display area 102 transitions smoothly, improving the phenomenon of poor display caused by the large reflectivity difference between the first display area 101 and the second display area 102.

[0111] In addition, this application embodiment also provides a display device, which includes a sensor and a display panel as described in the above embodiments, wherein the sensor is disposed on one side of the display panel corresponding to the first display area 101.

[0112] In this embodiment, the display panel provides a differentiated distribution of the first light-shielding part 21, which ensures that the sensor has sufficient light intake and allows for a smooth transition between the reflectivity difference between the first display area 101 and the second display area 102, thus improving the display defects caused by the large reflectivity difference between the first display area 101 and the second display area 102.

[0113] It is understood that since the display device has the same display panel as in the above embodiments, the display device has the same beneficial effects as the display panel described in the above embodiments, and will not be repeated here.
