Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] In the existing technology, full screen with high screen-to-body ratio has gradually become one of the important directions of current panel design. In order to increase the screen-to-body ratio, it is often necessary to compress the width of the border area. It should be noted that on the basis of compressing the border width, the irregular (rounded) corners of the existing display panel are also a common design.

[0003] However, for the portion of the frame area corresponding to the rounded four corners (which may be referred to as the arc frame area), considering that the design of the frame area must give priority to avoiding pixels and the change in the curvature inside and outside the frame area, the width of the arc frame area often decreases along the extension direction. Since the width of the frame area is relatively small, when the width of the arc frame area is compressed, some wiring structures provided in the frame area are likely to be closer to the outer edge of the frame area. In this case, some of the manufacturing processes (such as the cutting process) of the display panel are likely to damage the above wiring structures, and the above wiring structures are more susceptible to corrosion by external water and oxygen, affecting the performance of the display panel. Summary of the invention

[0004] In view of this, the present application provides a display panel and a display device to solve the problem that part of the wiring structure in the frame area is too close to the outer edge of the frame area.

[0005] In a first aspect, the present application provides a display panel comprising a non-display area and a display area, wherein the non-display area at least partially surrounds the display area, and a scanning drive circuit is provided in the non-display area. The scanning drive circuit transmits a scanning signal to a sub-pixel in the display area through a scanning signal line, and at least a portion of the scanning signal line extends along a first direction.

[0006] The non-display area includes a first area, a second area and a transition area. The first area extends along a second direction, and the second direction intersects the first direction. The second area is bent and the opening corresponding to the edge of the second area faces the display area. The edge of the transition area is connected to the edge of the first area and the edge of the second area.

[0007] A plurality of sub-pixels are arranged in the display area, including first-type sub-pixels in the plurality of sub-pixels, and the first-type sub-pixels are located in the edge area of ​​the display area. Along the first direction, the first-type sub-pixels overlap with the first area and the transition area.

[0008] The width of the transition area is greater than or equal to the width of the first area.

[0009] Second aspect, based on the same inventive concept, the present application provides a display device, including a display panel as provided in the first aspect.

[0010] In the present application, for the part of the scan driving circuit located in the transition region, the reason for the weak corrosion resistance of this part is as follows: when the width of the non-display area is compressed, the distance between the scan driving circuit and the outer edge of the non-display area (hereinafter referred to as the edge distance) decreases. Then, when external water and oxygen erode the display panel 10, the scan driving circuit has a higher risk of being eroded. Therefore, the present application ensures that the scan driving circuit has a sufficiently large setting space in the transition region by setting the width of the transition region to be greater than or equal to the width of the first region, ensuring that the above-mentioned edge distance is large, reducing the risk of the scan driving circuit being eroded, and further improving the corrosion resistance of the scan driving circuit. In addition, compared with the above-mentioned edge distance corresponding to the first region, the edge distance corresponding to the scan driving circuit in the transition region can be larger. Correspondingly, the corrosion resistance corresponding to the scan driving circuit in the transition region is stronger, and when the display panel is subjected to a cutting process, the risk of damage to the part of the scan driving circuit in the transition region is also smaller.

Detailed implementation manners

[0013] To better understand the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] Figure 1 Schematic diagram of a partial structure of a display panel related to this application.

[0019] In the prior art, as Figure 1 shown, the popularization of the full-screen design has compressed the width of the border area 01' on the existing display panel 10', resulting in a relatively close distance between some of the wiring structures 011' disposed in the border area 01' and the outer edge of the border area 01'.

[0020] In addition to the narrow frame design, the four corners of the existing display panel 10' are also shaped (rounded) and become a more common design method. Figure 1 As shown, the portion of the border area 01 ′ corresponding to the irregularly shaped area is bent along the edge of the irregularly shaped area, and part of the wiring structure 011 ′ in the border area 01 ′ is also bent accordingly.

[0021] It should be noted that the design of the border area 01' often needs to follow the principle of giving priority to the distribution of pixels 021' in the display area 02', that is, the border area 01' needs to avoid pixels 021'. However, there are edge pixels 021a' that are relatively close to the border area 01' in the existing display panel 10', and the edge pixels 021a' overlap with the bent portion 01a' and the non-bent portion 01b' of the border area 01' in the first direction X. In order to avoid the edge pixel 021a', along the second direction Y, the inner edge of the border area 01' (the edge close to the display area 02') is bent later than the outer edge of the border area 01' (the edge away from the display area 02'). This results in the situation where the width of the border area 01' is reduced from w2 to w1 during the transition from the non-bent portion 01b' to the bent portion 01a' along the second direction Y. Therefore, compared with the non-bending portion 01b', the partial wiring structure 011' is closer to the outer edge of the frame area 01' in the bending portion 01a' (the corresponding area of ​​width w1). In this case, the partial wiring structure 011' is more susceptible to external water and oxygen erosion, thereby affecting the display function of the existing display panel 10'. In particular, if it is necessary to perform a cutting process on the edge of the existing display panel 10', the partial wiring structure 011' is also easily damaged by the cutting process, which damages the functional integrity of the partial wiring structure 011'.

[0022] Figure 2 A schematic diagram of a partial structure of a display panel provided in the present application, Figure 3 Another schematic diagram of a partial structure of a display panel provided in the present application.

[0023] In view of the above problems, combined with Figure 2 and Figure 3 The present application provides a display panel 10 , including a non-display area 01 and a display area 02 , wherein the non-display area 01 at least partially surrounds the display area 02 .

[0024] The non-display area 01 is provided with a scan driving circuit 011 , which may include a cascaded shift register and some signal lines connected thereto, etc. In addition, the scan driving circuit 011 may be extended in a part of the non-display area 01 .

[0025] The scan driving circuit 011 transmits a scan signal to the sub-pixels 021 in the display area 02 through the scan signal line 03, and at least a part of the scan signal line 03 extends along the first direction X. The sub-pixels 021 may include a pixel circuit for providing an electrical signal to the light-emitting device, and the pixel circuit in the sub-pixels 021 can generate a driving current for driving the light-emitting device to emit light after receiving the scan signal transmitted by the scan driving circuit 011.

[0026] The non-display area 01 includes a first area 01a, a second area 01b, and a transition area 01c.

[0027] The first area 01a extends along the second direction Y, and the second direction Y intersects with the first direction X. Among them, the first area 01a may be a non-bent part in the non-display area 01. Along the second direction Y, the first area 01a may be located on a side of the transition area 01c away from the second area 01b.

[0028] The second area 01b is bent and the opening corresponding to the edge of the second area 01b faces the display area 02, and at least a part of the second area 01b can be regarded as being bent from the second direction Y to the first direction X.

[0029] The edge of the transition area 01c is connected to the edge of the first area 01a and the edge of the second area 01b. At this time, the width corresponding to the part of the transition area 01c connected to the first area 01a may be equal to the width of the first area 01a, and the width corresponding to the part of the transition area 01c connected to the second area 01b may be equal to the width of the second area 01b.

[0030] It should be noted that at least a part of the inner edge (the edge close to the display area 02) of the transition area 01c may not extend along a straight line. The outer edge (the edge far from the display area 02) of the transition area 01c may be connected to the outer edge of the first area 01a at the first intersection point A, and the inner edge of the transition area 01c may be connected to the inner edge of the first area 01a at the second intersection point B, and the first intersection point A and the second intersection point B may overlap along the first direction X.

[0031] A plurality of sub-pixels 021 are provided in the display area 02, and the plurality of sub-pixels 021 include first-type sub-pixels 021a, and the first-type sub-pixels 021a are located in the edge area of the display area 02. Relative to other sub-pixels 021, at least a part of the first-type sub-pixels 021a may be closer to the transition area 01c. Along the first direction X, the first-type sub-pixels 021a overlap with both the first area 01a and the transition area 01c. At this time, the distribution of the first-type sub-pixels 021a is likely to affect the width change of the non-display area 01. If it is necessary to ensure that the width of the non-display area 01 (in the extension direction of the non-display area 01) remains unchanged, the shape, area and other characteristics of the first-type sub-pixels 021a can be adjusted.

[0032] Among them, in combination with Figure 2 and Figure 3 , the width w1 of at least a part of the transition region 01c is greater than or equal to the width w2 of the first region 01a.

[0033] For the part of the scan driving circuit located in the transition region, the reason for the weak corrosion resistance of this part is that when the width of the non-display area is compressed, the distance between the scan driving circuit and the outer edge of the non-display area (hereinafter referred to as the edge line distance) decreases. Then, when external water and oxygen erode the display panel 10, the risk of the scan driving circuit being eroded is relatively high. In the embodiment of the present application, when w1 = w2, it helps to achieve a sufficiently large setting space for the scan driving circuit in the transition region, ensuring that the above-mentioned edge line distance is relatively large, reducing the risk of damage to the scan driving circuit, and thus improving the corrosion resistance of the scan driving circuit. The above-mentioned corrosion resistance can also be understood as the ability of the scan driving circuit 011 to resist external water and oxygen erosion. In addition, when w1 > w2, compared with the above-mentioned edge line distance corresponding in the first region 01a, the edge line distance corresponding to the scan driving circuit 011 in the transition region 01c can be larger. Therefore, this design further increases the available setting space corresponding to the scan driving circuit in the transition region, helps to further increase the above-mentioned edge line distance, and thus effectively improves the corrosion resistance corresponding to the scan driving circuit 011 in the transition region 01c; at the same time, when the display panel 10 is subjected to a cutting process, the risk of damage to the part of the scan driving circuit 011 in the transition region 01c is also relatively small.

[0034] Figure 4 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0035] In an embodiment of the present application, as Figure 4 shown, the length L1 of at least a part of the first type of sub-pixels 021a in the first direction X is less than its length L2 in the second direction Y.

[0036] In the embodiment of the present application, when L1 is less than L2, it means that the first type of sub-pixel 021a has a smaller space requirement in the first direction X than the space requirement in the second direction Y. At this time, a part of the area on the display panel 10 originally used to set the first type of sub-pixel 021a can be divided into a non-display area 01 to provide the space required for the inner edge of the transition area 01c to bend inward. Specifically, it can be understood that for some sub-pixels 021 close to the transition area 01c, the length of these sub-pixels 021 in the first direction X is reduced, and these sub-pixels 021 are moved along the first direction X, so as to reserve the space for the inner edge of the non-display area 01 to bend inward. At this time, the existence of this reserved space avoids the situation where the width of the transition area 01c is less than the width of the first area 01a; these sub-pixels 021 can correspond to the first type of sub-pixels 021a.

[0037] In an embodiment of the present application, as Figure 4 shown, the display panel 10 further includes a first pixel group 020, and the first pixel group 020 includes a plurality of first type of sub-pixels 021a.

[0038] Among them, the areas corresponding to the respective first type of sub-pixels 021a in the first pixel group 020 are the same.

[0039] In the embodiment of the present application, the areas corresponding to the different first type of sub-pixels 021a in the first pixel group 020 are the same, which means that the light-emitting areas corresponding to the light-emitting devices in the respective first type of sub-pixels 021a can be the same, which helps to improve the brightness uniformity of the display screen.

[0040] In a possible implementation manner, as Figure 4 shown, the shapes of the respective first type of sub-pixels 021a in the same first pixel group 020 are the same. In this implementation manner, the shapes of the different first type of sub-pixels 021a are the same and the areas are equal, which helps to reduce the manufacturing difficulty of the sub-pixels 021.

[0041] Figure 5 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0042] In an embodiment of the present application, as Figure 5 shown, the first pixel group 020 includes a first sub-pixel 21a1 and a second sub-pixel 21a2 adjacent to each other along the first direction X. Along the first direction X, the first sub-pixel 21a1 is located between the second sub-pixel 21a2 and the transition area 01c. At this time, the first sub-pixel 21a1 is closer to the transition area 01c than the second sub-pixel 21a2, so the setting conditions (shape, area, etc.) of the first sub-pixel 21a1 are more likely to affect the width size of the transition area 01c.

[0043] The length L21 of the first sub-pixel 21a1 in the second direction Y is less than the length L22 of the second sub-pixel 21a2 in the second direction Y.

[0044] In the embodiment of the present application, since L21 < L22, the first sub-pixel 21a1 and the second sub-pixel 21a2 can form a stepped-like structure, which helps to reserve space for the bending of the non-display area 01 during the preparation of the first pixel group 020, preventing the width of the transition area 01c from being too small, and is beneficial to improving the corrosion resistance of the scan driving circuit 011.

[0045] In a possible implementation, as Figure 5 shown, since L21 < L22, considering that the area of the first sub-pixel 21a1 can be equal to the area of the second sub-pixel 21a2, the length L11 of the first sub-pixel 21a1 in the first direction X can be greater than the length L12 of the second sub-pixel 21a2 in the first direction X.

[0046] Figure 6 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0047] In an embodiment of the present application, as Figure 6 shown, the non-display area 01 further includes a third area 01d extending along the first direction X, and the edge of the third area 01d is connected to the edge of the second area 01b.

[0048] Among the multiple first-type sub-pixels 021a, there are a first sub-pixel 21a1 and a second sub-pixel 21a2 adjacent along the first direction X. Along the first direction X, the first sub-pixel 21a1 is located between the second sub-pixel 21a2 and the transition area 01c.

[0049] The orthographic projections of the first sub-pixel 21a1 and the second sub-pixel 21a2 satisfy the same shape and the same area.

[0050] Along the second direction Y, the distance H2 between the second sub-pixel 21a2 and the third area 01d is less than the distance H1 between the first sub-pixel 21a1 and the third area 01d.

[0051] In the embodiment of the present application, since H2 < H1, the first sub-pixel 21a1 and the second sub-pixel 21a2 can form a stepped-like structure, which helps to reserve a space for the bending of the non-display area 01 and prevent the width of the transition area 01c from being too small. In addition, since the first sub-pixel 21a1 and the second sub-pixel 21a2 have the same shape and the same area, it can be understood that on the basis that multiple first-type sub-pixels 021a in the present application have the same shape (the same shape and the same area), by adjusting the relative positions between the first sub-pixel 21a1 and the second sub-pixel 21a2, the width of the transition area 01c is made greater than or equal to the width of the first area 01a.

[0052] Figure 7 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0053] In an embodiment of the present application, as Figure 7 shown, the first sub-pixel 21a1 is electrically connected to the first scanning line 031 at the first node P1, and the second sub-pixel 21a2 is electrically connected to the first scanning line 031 at the second node P2. The first scanning line 031 can provide scanning signals to the first sub-pixel 21a1 and the second sub-pixel 21a2 respectively. It should be noted that the settings of the first scanning line 031 can be adjusted according to the distribution between the first sub-pixel 21a1 and the second sub-pixel 21a2, for example, features such as the extending direction, extending length, and relative position of the first scanning line 031 can be adjusted.

[0054] Among them, the extending direction of the orthographic projection of the part of the first scanning line 031 between the first node P1 and the second node P2 and the second direction Y is the angle θ, and the angle θ is an obtuse angle and the opening corresponding to the angle θ faces away from the transition area 01c.

[0055] In the embodiment of the present application, the extending direction of a part of the first scanning line 031 (referred to as the corresponding part here) and the second direction Y form an obtuse angle θ, which means that the extending direction of the above corresponding part can be adapted to the above two first-type sub-pixels 021a that form a stepped-like structure. That is, in the present application, while adjusting the relative positions between different first-type sub-pixels 021a, the distribution of the corresponding scanning signal lines 03 for each of them is also adaptively adjusted.

[0056] Figure 8 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0057] In an embodiment of the present application, as Figure 8As shown, among the multiple sub-pixels 021, there are also second-type sub-pixels 021b. Compared with the first-type sub-pixels 021a, the second-type sub-pixels 021b are farther from the transition region 01c, and the second-type sub-pixels 021b overlap with the first-type sub-pixels 021a in the second direction Y. Along the second direction Y, the second-type sub-pixels 021b can be located on the side of the first-type sub-pixels 021a away from the second region 01b.

[0058] Among them, the area of the second-type sub-pixels 021b is equal to the area of the first-type sub-pixels 021a, and the length L3 of the second-type sub-pixels 021b in the first direction X is greater than the length L1 of the first-type sub-pixels 021a in the first direction X.

[0059] In the embodiment of the present application, the setting method with the same area between the second-type sub-pixels 021b and the first-type sub-pixels 021a helps to make the light-emitting area of the first-type sub-pixels 021a the same as that of the first-type sub-pixels 021a, which is beneficial to improving the brightness uniformity of different regions of the display screen. In addition, when L3 > L1, compared with the space length occupied by the second-type sub-pixels 021b in the first direction X, the space length occupied by the first-type sub-pixels 021a in the first direction X is smaller, which is beneficial to reserve the space for the inward bending of the non-display area 01, and further helps to improve the corrosion resistance of the scanning driving circuit 011 in the transition region 01c.

[0060] In an embodiment of the present application, as Figure 8 shown, along the first direction X, the distance H3 between the second-type sub-pixels 021b and the first region 01a is less than the distance H4 between the first-type sub-pixels 021a and the first region 01a.

[0061] In the embodiment of the present application, compared with the second-type sub-pixels 021b, the first-type sub-pixels 021a are farther from the first region 01a in the first direction X. This design method is more conducive to adjusting the first-type sub-pixels 021a to avoid the bent part of the non-display area 01, helps to improve the degree of inward bending of the transition region 01c, and increases the distance between the part of the scanning driving circuit 011 in the transition region 01c and the outer edge of the non-display area 01.

[0062] Figure 9 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0063] In an embodiment of the present application, as Figure 9 shown, the non-display area 01 further includes a third region 01d extending along the first direction X, and the edge of the third region 01d is connected to the edge of the second region 01b.

[0064] Among them, the closer to the third region 01d, the larger the first pitch ΔL corresponding to the first type of sub-pixel 021a. The first pitch ΔL is the pitch between the edge of the first type of sub-pixel 021a facing the first region 01a and the first region 01a in the first direction X.

[0065] In the setting manner of the embodiment of the present application, the extending direction of the projection of the side of the first type of sub-pixel 021a facing the transition region 01c can be inclined relative to the second direction Y, which helps to reserve space for the non-display area 01 to be bent inward.

[0066] In a possible implementation manner, as Figure 9 shown, along the second direction Y, the width L1 of the first type of sub-pixel 021a can remain unchanged.

[0067] Figure 10 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0068] In a possible implementation manner, as Figure 10 shown, the closer to the third region 01d, the smaller the width L1 of the first type of sub-pixel 021a can be.

[0069] In a possible implementation manner, as Figure 10 shown, the orthographic projection shape of the first type of sub-pixel 021a can be triangular.

[0070] Figure 11 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0071] In an embodiment of the present application, as Figure 11 shown, the display panel 10 further includes a plurality of data signal lines 04, and the data signal lines 04 can be located in the display area 02. The sub-pixels 021 receive the data signals transmitted by the data signal lines 04, and the above data signals can be used to participate in the process of generating a driving current in the pixel circuit of the sub-pixels 021.

[0072] The data signal line 04 includes a first portion 041, the first portion 041 is located on the side of its corresponding first type of sub-pixel 021a close to the transition region 01c, and the tangent of the first portion 041 is parallel to the edge of the first type of sub-pixel 021a facing the transition region 01c.

[0073] In addition to the first type of sub-pixels 021a, the partial wiring structure in the display area 02, which is disposed between the first type of sub-pixels 021a and the transition area 01c, also easily affects the bending condition of the non-display area 01. In the embodiment of the present application, by setting the tangent of the first part 041 of the data signal line 04 to be parallel to the edge of the first type of sub-pixels 021a, it helps to set the data signal line 04 on the premise of avoiding the transition area 01c, and further improves the problem that the non-display area 01 is not bent in time in the rounded corner area.

[0074] Figure 12 It is a schematic diagram of a display device provided by the present application.

[0075] The present application provides a display device 20, as Figure 12 shown, the display device 20 includes the display panel 10 provided in the above embodiment. The display device 20 may be a mobile phone. In addition, the display device 20 may also be an electronic device such as a computer or a television.

[0076] The corrosion resistance corresponding to the scan driving circuit 011 in the display device 20 provided in the embodiment of the present application has been greatly improved.

[0077] For the same and similar parts among the various embodiments in this specification, reference can be made to each other. In particular, for the device embodiments and the terminal embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the description in the method embodiments.
