Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display panel and display device. Background Technology

[0002] With the rapid development of display panel technology, users have increasingly higher requirements for display panels. Among these requirements, users pay particular attention to the display effect of the display panel, as a good display effect can provide users with a better visual experience.

[0003] Currently, the display effect of a display panel can be improved through algorithmic compensation. However, with the increase of usage time, the display panel will reappear with jagged edges and color shifts, resulting in a deterioration in its display effect. Summary of the Invention

[0004] This application provides a display panel and a display device, the display panel having a better display effect.

[0005] A first aspect of this application provides a display panel having a first display area and a second display area. The first display area surrounds at least a portion of the second display area. The display panel includes a first sub-pixel group and a second sub-pixel group. The first sub-pixel group is located in the first display area and includes irregularly shaped sub-pixels and non-irregularly shaped sub-pixels. The irregularly shaped sub-pixels have irregularly shaped edges, the shape of which corresponds to the shape of the edge of the first display area away from the second display area. The second sub-pixel group is located in the second display area and includes a plurality of second sub-pixels arranged in an array. The pixel area S21 of the second sub-pixels is larger than the pixel area S11 of the irregularly shaped sub-pixels and the pixel area S12 of the non-irregularly shaped sub-pixels.

[0006] In the display panel provided in this application, the first sub-pixel group located in the first display area includes irregularly shaped sub-pixels and non-irregularly shaped sub-pixels. The irregularly shaped sub-pixels have irregularly shaped edges, and these edges are adapted to the shape of the edge of the first display area away from the second display area, thus reducing jagged edges at the edge of the first display area. Furthermore, the pixel area of ​​the irregularly shaped sub-pixels and non-irregularly shaped sub-pixels is smaller than the pixel area of ​​the second sub-pixels. This allows the luminous efficiency attenuation rates of the first and second display areas to become more consistent, or even identical. Therefore, as the display panel is used over time, the brightness difference between the first and second display areas can be reduced, effectively mitigating the re-emergence of color shift in the display panel. Thus, the display panel provided in this application has a better display effect.

[0018] Optionally, the pixel area S12c of the third non-irregular sub-pixel is less than or equal to the pixel area S12b of the second non-irregular sub-pixel.

[0039] Before describing the technical solutions provided by the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0040] With the rapid development of display panel technology, users have increasingly higher requirements for display panels. Among these requirements, users pay particular attention to the display effect of the display panel, as a good display effect can provide users with a better visual experience.

[0041] To improve the display effect of display panels, the Spread Reduction (SPR) algorithm is commonly used in related technologies to weaken and compensate for the display boundaries, mitigating issues such as jagged edges and color shifts. With prolonged use, the luminous efficiency of the display panel decreases, and this decrease is more pronounced with longer usage time and at higher brightness levels. While the aforementioned weakening compensation method shows significant improvement in the initial display performance, after extended use, the luminous efficiency of pixels treated with the SPR algorithm becomes higher than that of pixels without the algorithm. This leads to increased brightness in the weakened areas, causing jagged edges and color shifts to reappear, resulting in a deterioration in the overall display quality.

[0042] In view of this, this application provides a display panel and a display device, the display panel having a better display effect.

[0043] The preferred embodiments of the display panel and display device disclosed in this application are described in detail below with reference to the accompanying drawings. Compared with the embodiments shown in the drawings, the feasible embodiments within the scope of protection of this application may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, without departing from the spirit of this application, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0044] Display panel

[0045] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 This application provides a schematic diagram of the structure of a display panel according to some embodiments. Figure 2 A schematic diagram of the structure of a display panel provided in some other embodiments of this application is shown.

[0047] like Figure 1 and Figure 2 As shown, the display panel 100 has a first display area AA1 and a second display area AA2. The first display area AA1 surrounds at least a portion of the second display area AA2. The display panel 100 includes a first sub-pixel group 10 and a second sub-pixel group 20. The first sub-pixel group 10 is located in the first display area AA1 and includes irregularly shaped sub-pixels 11 and non-irregularly shaped sub-pixels 12. The irregularly shaped sub-pixels 11 have irregularly shaped edges 111, the shape of which is adapted to the shape of the edge of the first display area AA1 away from the second display area AA2. The second sub-pixel group 20 is located in the second display area AA2 and includes a plurality of second sub-pixels 21 arranged in an array. The pixel area S21 of the second sub-pixels 21 is larger than the pixel area S11 of the irregularly shaped sub-pixels 11 and the pixel area S12 of the non-irregularly shaped sub-pixels 12.

[0048] In this application, the irregular sub-pixel 11 refers to a sub-pixel whose shape differs from that of other sub-pixels in the display area. For example, the non-irregular sub-pixel 12 and the second sub-pixel 21 have shapes such as squares and rectangles, while the irregular sub-pixel 11 has a triangular shape. Furthermore, the irregular edge 111 of the irregular sub-pixel 11 is adapted to the shape of the edge of the first display area AA1 away from the second display area AA2. It can be understood that the irregular edge 111 of the irregular sub-pixel 11 can be set according to the shape of the edge of the first display area AA1 away from the second display area AA2. For example, the shape of the edge of the first display area AA1 away from the second display area AA2 is a straight line (e.g.,...). Figure 1 As shown), the shape of the irregular edge 111 is also a straight line, or the shape of the edge of the first display area AA1 away from the second display area AA2 is an arc (as shown). Figure 2 As shown in the figure, the shape of the irregular edge 111 is also an arc-shaped edge.

[0049] Pixel area refers to the area of ​​the region enclosed by the edges of each pixel. It can be understood as the area of ​​the region enclosed by the edges of sub-pixels projected onto each display area.

[0050] In the display panel 100 provided in this application, the first sub-pixel group 10 located in the first display area AA1 includes irregularly shaped sub-pixels 11 and non-irregularly shaped sub-pixels 12. The irregularly shaped sub-pixels 11 have irregularly shaped edges 111, and these edges 111 are adapted to the shape of the edge of the first display area AA1 away from the second display area AA2, thus reducing jagged edges at the edge of the first display area AA1. Furthermore, the pixel area of ​​the irregularly shaped sub-pixels 11 and non-irregularly shaped sub-pixels 12 is smaller than the pixel area of ​​the second sub-pixels 21. This allows the luminous efficiency attenuation rates of the first display area AA1 and the second display area AA2 to become more consistent. Therefore, as the display panel 100 is used for longer periods, the brightness difference between the first display area AA1 and the second display area AA2 can be reduced, effectively mitigating the recurring color shift in the display panel 100. Therefore, the display panel 100 provided in this application has a better display effect.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the irregular sub-pixels 11 are arranged at intervals along the edge of the first display area AA1 away from the second display area AA2.

[0052] In the above embodiments, the irregular edge 111 of the irregular sub-pixel 11 is adapted to the edge of the first display area AA1 that is far away from the second display area AA2. Combined with the arrangement of the irregular sub-pixel 11, the jaggedness of the edge of the first display area AA1 that is far away from the second display area AA2 can be further reduced, thereby further improving the display effect of the display panel 100.

[0053] In addition, while irregularly shaped sub-pixels 11 are arranged at intervals along the edge of the first display area AA1 away from the second display area AA2, irregularly shaped sub-pixels 11 can also be arranged between the edge of the first display area AA1 away from the second display area AA2 and non-irregularly shaped sub-pixels 12, which can significantly reduce the generation of jagged edges in the display panel 100.

[0054] In other embodiments of this application, the irregular sub-pixels 11 may also be arranged at intervals along the edge of the first display area AA1 near the second display.

[0055] When the horizontal distance between the irregular edge 111 of the irregular sub-pixel 11 and the edge of the first display area AA1 away from the second display area AA2 is within a suitable range, the jagged edge problem of the display panel 100 can be further improved.

[0056] In some examples, the horizontal distance between the irregular edge 111 of the irregular sub-pixel 11 and the edge of the first display area AA1 away from the second display area AA2 is less than or equal to 50 μm.

[0057] In some embodiments of this application, the irregular edge 111 of the irregular sub-pixel 11 coincides with the edge of the first display area AA1 away from the second display area AA2. It can be understood that the horizontal distance between the irregular edge 111 of the irregular sub-pixel 11 and the edge of the first display area AA1 away from the second display area AA2 is 0, which can effectively reduce the generation of edge jaggedness of the display panel 100 and significantly improve its display effect.

[0058] In this application, the pixel area of ​​each sub-pixel in the first sub-pixel group 10 and the second sub-pixel group 20 is related to the luminous efficiency attenuation rate. Therefore, by adjusting the pixel area of ​​the sub-pixels in the first sub-pixel group 10 and / or the pixel area of ​​the sub-pixels in the second sub-pixel group 20, the luminous efficiency attenuation rates of the first display area AA1 and the second display area AA2 can be made more consistent. In some embodiments of this application, the ratio S11 / S21 of the pixel area S11 of the irregular sub-pixel 11 to the pixel area S21 of the second sub-pixel 21 satisfies: 0.01 ≤ S11 / S21.

[0059] In the above embodiments, the ratio S11 / S21 of the pixel area S11 of the irregular sub-pixel 11 and the pixel area S21 of the second sub-pixel 21 satisfies the above relationship, which can reduce the appearance of jagged edges on the display panel 100, and also help to improve the first display area AA1 and the second display area AA2.

[0060] The luminous efficiency decay rate tends to be uniform, which can reduce the brightness difference between the first display area AA1 and the second display area AA2 after long-term use of the display panel 100, thereby reducing the reproduction of color deviation of the display panel 100.

[0061] In some other embodiments of this application, the ratio S11 / S21 of the pixel area S11 of the irregular sub-pixel 11 to the pixel area S21 of the second sub-pixel 21 satisfies: 0.25≤S11 / S21≤0.5.

[0062] In some examples, the ratio S11 / S21 of the pixel area S11 of the irregular sub-pixel 11 to the pixel area S21 of the second sub-pixel 21 can be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5 or any range of two of the above values, such as 0.01-0.5, 0.05-0.45, 0.1-0.4, 0.15-0.35 or 0.2-0.3.

[0063] In some embodiments of this application, the pixel area S11 of the irregular sub-pixel 11 is the same as the pixel area S12 of its adjacent non-irregular sub-pixel 12.

[0064] In the above embodiments, it is understood that the ratio S12 / S21 of the pixel area S12 of the non-irregular sub-pixel 12 and the pixel area S21 of the second sub-pixel 21 satisfies: 0.01≤S12 / S21, optionally, 0.25≤S12 / S21≤0.5. This can further make the luminous efficiency attenuation in the first display area AA1 and the second display area AA2 more consistent. After long-term use, the brightness difference between the first display area AA1 and the second display area AA2 of the display panel 100 will be reduced, and the probability of color shift of the display panel 100 will be reduced.

[0065] Please refer to Figure 3 , Figure 3 A schematic diagram of the structure of a display panel 100 provided in some embodiments of this application is shown.

[0066] like Figure 3 As shown, in some embodiments of this application, the irregular sub-pixel 11 includes a first irregular sub-pixel 11a and a second irregular sub-pixel 11b. The first irregular sub-pixel 11a has one irregular edge 111, and the second irregular sub-pixel 11b has at least two irregular edges 111.

[0067] In the above embodiments, it is understood that the first irregular sub-pixel 11a is located at a non-corner of the first display area AA1, and the second irregular sub-pixel 11b is located at a corner of the first display area AA1. The corner refers to the connection point of two edges in the first display area AA1. Therefore, in display panels 100 of various shapes, the arrangement of the first irregular sub-pixel 11a and the second irregular sub-pixel 11b can reduce the probability of jagged edges recurring in the display panel 100, thereby further improving the display effect of the display panel 100.

[0068] In some embodiments of this application, the pixel area S11a of the first irregular sub-pixel 11a is greater than the pixel area S11b of the second irregular sub-pixel 11b.

[0069] like Figure 3 As shown, in some embodiments of this application, the non-irregular sub-pixel 12 includes a first non-irregular sub-pixel 12a and a second non-irregular sub-pixel 12b. The first non-irregular sub-pixel 12a is disposed away from the edge of the second display area AA2, and the second non-irregular sub-pixel 12b is disposed close to the edge of the second display area AA2. The pixel area S12b of the second non-irregular sub-pixel 12b is greater than or equal to the pixel area S12a of the first non-irregular sub-pixel 12a.

[0070] In the above embodiments, the arrangement of the first non-irregular sub-pixel 12a and the setting of the pixel area of ​​the second non-irregular sub-pixel 12b can help reduce the probability of jagged edges at the edge of the display panel 100, while also reducing the brightness difference between the first display area AA1 and the second display area AA2, thereby reducing the probability of color shift reproduction in the display panel 100.

[0071] In some embodiments of this application, the pixel area S12b of the second non-irregular sub-pixel 12b is larger than the pixel area S12a of the first non-irregular sub-pixel 12a. This can significantly reduce the probability of jagged edges reappearing at the edges of the display panel 100, while also effectively reducing the brightness difference between the first display area AA1 and the second display area AA2, thereby reducing the probability of color shift reproduction in the display panel 100.

[0072] In some embodiments of this application, the shapes of the first non-irregular sub-pixel 12a, the second non-irregular sub-pixel 12b, and the second sub-pixel 21 are the same.

[0073] In some examples, the shape of the second sub-pixel 21 can be a rectangle, a square, a parallelogram, a rhombus, etc.

[0074] like Figure 3 As shown, in some embodiments of this application, the non-irregular sub-pixel 12 further includes a third non-irregular sub-pixel 12c, which is disposed near the corner of the first display area AA1. The third non-irregular sub-pixel 12c is closer to the edge of the first display area AA1 than the second non-irregular sub-pixel 12b. The pixel area S12c of the third non-irregular sub-pixel 12c is greater than or equal to the pixel area S12a of the first non-irregular sub-pixel 12a.

[0075] In these embodiments, the display panel 100 is configured into different shapes according to actual application requirements. Therefore, the configuration of the third non-irregular sub-pixel 12c can reduce the probability of jagged edges recurring in the display panel 100, thereby further improving the display effect of the display panel 100.

[0076] In some other embodiments of this application, the pixel area S12c of the third non-irregular sub-pixel 12c is less than or equal to the pixel area S12b of the second non-irregular sub-pixel 12b.

[0077] In some embodiments of this application, the subpixel density of the first display area AA1 is greater than or equal to the subpixel density of the second display area AA2.

[0078] In the above embodiments, the setting of the sub-pixel density of the first display area AA1 and the sub-pixel density of the second display area AA2 can help reduce the brightness difference between the first display area AA1 and the second display area AA2, reduce the probability of color shift in the display panel 100, and thus improve the display effect of the display panel 100.

[0079] In some other embodiments of this application, the subpixel density of the first display area AA1 is greater than the subpixel density of the second display area AA2.

[0080] In some embodiments of this application, the ratio of the luminous efficiency attenuation amplitude v11 of the irregular sub-pixel 11 to the luminous efficiency attenuation amplitude v2 of the second sub-pixel 21 satisfies: 0.9≤v11 / v2≤1.05.

[0081] In the above embodiments, the ratio of the luminous efficiency attenuation amplitude v11 of the irregular sub-pixel 11 to the luminous efficiency attenuation amplitude v2 of the second sub-pixel 21 satisfies the above relationship, which can further reduce the brightness difference between the first display area AA1 and the second display area AA2, thereby improving the display effect of the display panel 100.

[0082] In some other embodiments of this application, the luminous efficiency attenuation amplitude v12 of the non-irregular sub-pixel 12 is equal to the luminous efficiency attenuation amplitude v11 of the irregular sub-pixel 11.

[0083] In some other embodiments of this application, the luminous efficiency attenuation amplitude v11 of the irregular sub-pixel 11 is equal to the luminous efficiency attenuation amplitude v2 of the second sub-pixel 21. This can further reduce the brightness difference between the first display area AA1 and the second display area AA2 after long-term use, thereby improving the display effect of the display panel 100.

[0084] In some examples, the luminous efficiency attenuation of the irregular subpixel 11 can be 0.003 nit / h to 0.3 nit / h.

[0085] In some embodiments of this application, the display panel 100 further includes a substrate, a device layer located between the substrate and the pixel group layer, and a pixel definition layer located on the side of the device layer facing away from the substrate. The substrate may be made of a light-transmitting material such as glass or polyimide (PI). The device layer may include a first pixel group circuit and a second pixel group circuit. The first pixel group circuit is electrically connected to the irregularly shaped sub-pixels 11 and the non-irregularly shaped sub-pixels 12, respectively, for driving the irregularly shaped sub-pixels 11 and the non-irregularly shaped sub-pixels 12 to display. The second pixel group circuit may be electrically connected to the second sub-pixel 21 for driving the second sub-pixel 21 to display.

[0086] In some embodiments of this application, the irregularly shaped sub-pixel 11 includes a first light-emitting structure, a first electrode, and a second electrode stacked sequentially. The pixel definition layer includes an irregularly shaped sub-pixel opening, the first light-emitting structure is located within the irregularly shaped sub-pixel opening, the first electrode is located on the side of the first light-emitting structure facing the substrate, and the second electrode is located on the side of the first light-emitting structure facing away from the substrate. One of the first electrode and the second electrode is an anode, and the other is a cathode.

[0087] In this application, the non-irregular sub-pixel 12 has the same structure as the irregular sub-pixel 11 except for its shape, and will not be described again here.

[0088] In some embodiments of this application, the second sub-pixel 21 includes a second light-emitting structure, a third electrode, and a fourth electrode. The pixel definition layer includes a second sub-pixel opening, the second light-emitting structure is located within the second sub-pixel opening, the third electrode is located on the side of the second light-emitting structure facing the substrate, and the fourth electrode is located on the side of the second light-emitting structure facing away from the substrate. One of the third and fourth electrodes is an anode, and the other is a cathode.

[0089] In the embodiments of this application, the first and third electrodes are anodes, and the second and fourth electrodes are cathodes, as an example for explanation.

[0090] The first light-emitting structure and the second light-emitting structure may each include an OLED light-emitting layer. Depending on the design requirements of the first light-emitting structure and the second light-emitting structure, each may also include at least one of a hole injection layer, a hole transport layer, an electron injection layer, or an electron transport layer.

[0091] In some embodiments of this application, the first electrode is a light-transmitting electrode.
