Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] With the continuous development of display technology, "borderless" and "full-screen" displays have become research hotspots in the display field. A larger screen-to-body ratio brings users a superior visual experience and can display more information. Therefore, pursuing a larger screen-to-body ratio has become the mainstream development trend of display products.

[0003] In current technology, display products are constantly reducing bezels in pursuit of high screen-to-body ratios, and full-screen displays with perforated structures are becoming the latest design trend. These perforations can accommodate devices such as cameras and earpieces. Placing a camera within an opening in the display area maximizes the screen-to-body ratio.

[0004] Improving the display effect of this type of display panel has become an urgent technical problem to be solved. Summary of the Invention

[0005] The present invention provides a display panel and display device to reduce the degree of misalignment of connecting lines at tilted viewing angles.

[0006] In a first aspect, embodiments of the present invention provide a display panel including a display area, the display area including a first display area and a second display area, wherein the transmittance of the first display area is greater than the transmittance of the second display area;

[0007] The first display area includes connecting lines, and the connecting lines include first connecting lines. Multiple first connecting lines extend in different directions from the area near the center of the first display area toward the area away from the center of the first display area.

[0008] In a second aspect, embodiments of the present invention provide a display device, including the display panel described in the first aspect, and a light-sensing element;

[0009] The light-sensing element is located in the first display area, on the non-light-emitting side of the display panel.

[0010] This invention provides a display panel with connecting lines including a first connecting line. The first connecting line is arranged radially within a first display area, extending from a region near the center of the first display area towards a region away from the center of the first display area, in a direction radially or approximately radially relative to the center of the first display area. Here, radially refers to the direction from near the center of the first display area towards a direction away from the center of the first display area. This arrangement aligns with the principle that the viewing angle increases with distance from the center of the first display area. In other words, the extension direction of the first connecting line is consistent with the direction of increasing viewing angle, thereby reducing the degree of misalignment of the connecting line under tilted viewing angles.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0040] Figure 1 This is a top view schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 for Figure 1 A top-view structural diagram of the first display area in the middle, for reference. Figure 1 and Figure 2 The display panel includes a display area 100, which can be used for image display. The display area 100 includes a first display area 110 and a second display area 120, with the first display area 110 having a higher transmittance than the second display area 120. On one hand, the first display area 110 can be used for image display. On the other hand, the first display area 110 has higher transmittance, allowing light to pass through it to reach the non-light-emitting side of the display panel, i.e., the back of the display panel, enabling specific optical functions such as imaging.

[0041] The first display area 110 includes connecting lines 200, and the connecting lines 200 include first connecting lines 210. Multiple first connecting lines 210 extend in different directions from an area near the center O of the first display area 110. Figure 2 (As shown by the dashed circle) extends toward a region away from the center O of the first display area 110. In some alternative embodiments, the region at the center of the first display area refers to the area adjacent to the center O of the first display area.

[0042] It should be noted that the first connecting line 210 may pass through the center O of the first display area. In other embodiments, the first connecting line 210 may not pass through the center O of the first display area. The extension line of the first connecting line 210 may also not pass through the center O of the first display area.

[0043] The inventors discovered that the connecting lines 200 in the first display area 110 are misaligned under tilted viewing angles, leading to problems such as occlusion and diffraction. This invention provides a display panel where the connecting lines 200 include first connecting lines 210. The first connecting lines 210 are arranged radially within the first display area 110, extending from a region near the center of the first display area towards a region away from the center, in a direction radial to or close to the radial direction of the first display area 110. Radial refers to the direction from near the center O of the first display area 110 towards a direction away from the center O. For example, when the first display area is circular, the radial direction is parallel to the radius or diameter of the circle. This arrangement aligns with the principle that the viewing angle increases with distance from the center O of the first display area. In other words, the extension direction of the first connecting lines 210 is consistent with the direction of increasing viewing angle, thereby reducing the degree of misalignment of the connecting lines 200 under tilted viewing angles.

[0044] It needs to be explained that, Figure 3 This is a schematic diagram from a tilted perspective. Figure 4 This is a schematic diagram showing the misalignment of the connecting lines from an oblique perspective. (Refer to...) Figures 2-4 The plane on which the display panel is located is the XY plane, which is determined by the first direction X and the second direction Y. The vertical direction Z is perpendicular to the XY plane. The viewing angle θ is the angle between the observation angle and the vertical direction Z. Taking the center O of the first display area 110 as a reference, the viewing angle θ gradually increases from the direction closer to the center O of the first display area 110 toward the direction farther away from the center O of the first display area 110.

[0045] refer to Figures 2-4 The connecting line 200 includes a first height connecting line 2001. From an oblique viewing angle, the projection of the first height connecting line 2001 is a first projection connecting line 2003. In the XY plane, the first projection connecting line 2003 is offset. That is, the first projection connecting line 2003 from the oblique viewing angle is misaligned relative to the projection of the connecting line 200 from the normal viewing angle.

[0046] refer to Figures 2-4The connecting line 200 includes a first height connecting line 2001 and a second height connecting line 2002, which are located at different heights in the vertical direction Z. From an oblique viewing angle, the projection of the second height connecting line 2002 is a second projection connecting line 2004. In the XY plane, the second projection connecting line 2004 is offset. Furthermore, relative to the normal viewing angle where the first height connecting line 2001 and the second height connecting line 2002 are directly opposite each other, the positional relationship of the first projection connecting line 2003 and the second projection connecting line 2004 formed from the oblique viewing angle changes, resulting in an offset in the XY plane. That is, because the first height connecting line 2001 and the second height connecting line 2002 have different heights, the projections formed by the first height connecting line 2001 and the second height connecting line 2002 have different offsets from the oblique viewing angle, causing a change in the positional relationship of the first projection connecting line 2003 and the second projection connecting line 2004 formed by the first height connecting line 2001 and the second height connecting line 2002, respectively. Ultimately, from an oblique perspective, the first height connection line 2001 and the second height connection line 2002 are no longer aligned.

[0047] Optionally, refer to Figure 2 The first connecting line 210 includes a straight line segment, the radial component of which is greater than its tangential component. The radial component refers to the component of the straight line segment along the radial direction of the first display area 110. The tangential component refers to the component of the straight line segment along a direction perpendicular to the radial direction. A larger radial component means the straight line segment's extension direction is closer to the radial direction; a larger tangential component means the straight line segment's extension direction is closer to the direction perpendicular to the radial direction. Therefore, setting the radial component of the straight line segment to be greater than its tangential component makes the straight line segment's extension direction closer to the radial direction, increasing the consistency between the extension direction of the first connecting line 210 and the direction of the increased viewing angle, and reducing the degree of misalignment of the connecting line 200 under tilted viewing angles.

[0048] Optionally, refer to Figure 2 The first connecting line 210 is a straight line segment with a general extension direction or overall routing, and passes through the center O of the first display area 110. The straight line segment included in the first connecting line 210 only has a radial component and no tangential component. The extension direction of the straight line segment included in the first connecting line 210 is radial, and the extension direction of the straight line segment included in the first connecting line 210 is consistent with the direction of increasing viewing angle. Therefore, the extension direction of the first connecting line 210 is consistent with the direction of increasing viewing angle, reducing the degree of misalignment of the connecting line 200 under tilted viewing angle.

[0049] The traces in the display panel are not ideal straight lines or ideal straight segments to accommodate the arrangement direction of the sub-pixels; instead, curves are incorporated into some segments of the traces. However, for a specific trace's extension direction, it is usually along a fixed direction. Therefore, "the first connecting line 210 is a straight line segment" means that the approximate extension direction of the first connecting line 210 or the overall direction of the trace is a straight line segment.

[0050] In other embodiments, the extension of the first connecting line 210 passes through the center O of the first display area 110. The straight segment included in the first connecting line 210 has only a radial component and no tangential component. The extension direction of the first connecting line 210 is consistent with the direction of increasing viewing angle, reducing the degree of misalignment of the connecting line 200 under tilted viewing angle.

[0051] Figure 5 for Figure 1 Another top-view structural diagram of the first display area in the middle, for reference. Figure 1 and Figure 5 The first connecting line 210 includes a straight line segment. The line connecting the center of the straight line segment and the center O of the first display area 110 is denoted as the auxiliary connecting line 230. The angle between the auxiliary connecting line 230 and the first connecting line 210 is less than or equal to 45°. The center of the straight line segment is the center along its length. The auxiliary connecting line 230 does not correspond to any actual connecting line in the display panel; it is merely a virtual connecting line introduced for ease of description.

[0052] For example, refer to Figure 5 , Figure 5 The diagram illustrates a first connecting line 210, which includes a straight line segment FG. Point F is the endpoint of straight line segment FG near the center O of the first display area 110, and point G is the endpoint of straight line segment FG away from the center O of the first display area 110. The midpoint of straight line segment FG is point E, and the angle θ between straight line segment OE and straight line segment FG satisfies: θ ≤ 45°. Therefore, the radial component of the straight line segment included in the first connecting line 210 is greater than the tangential component of the straight line segment.

[0053] It should be noted that, in addition to including a straight line segment, the first connecting line 210 may also include multiple straight line segments, or it may also include curved segments. This is as long as the extension direction of the first connecting line 210 is radial to or close to the radial direction of the first display area 110.

[0054] Figure 6 for Figure 1 Another top-view structural diagram of the first display area in the middle, for reference. Figure 1 and Figure 6The first display area 110 includes a central area 1101 and a peripheral area 1102, with the peripheral area 1102 surrounding the central area 1101. The peripheral area 1102 is located between the central area 1101 and the second display area 120. The central area 1101 of the first display area 110 and the area near the center O of the first display area 110 can be the same area or different areas. A first connecting line 210 is located in the peripheral area 1102. The connecting line 200 also includes a second connecting line 220, which is located in the central area 1101. The second connecting line 220 extends along a first direction X and connects to the first connecting line 210. The first direction X intersects with the second direction Y. In other embodiments, the second connecting line 220 may also extend along the second direction Y. The larger the tilt angle, the more severe the misalignment. The tilt angles of each second connecting line 220 in the central area 1101 are relatively small, while the tilt angles of each first connecting line 210 in the peripheral area 1102 are relatively large. Thus, in the central region 1101, to reduce wiring difficulty, each of the second connecting lines 220 can be configured to extend along either the first direction X or the second direction Y. In the peripheral region 1102, to reduce the misalignment of the connecting lines 200 under tilted viewing angles, each of the first connecting lines 210 can be configured to radiate outwards from the center.

[0055] Figure 7 for Figure 1 A top-view structural diagram of region S1, for reference. Figure 1 and Figure 7 The second display area 120 includes a plurality of pixel units 300, which are arranged in an array along a first direction X and a second direction Y. (Refer to reference...) Figure 6 The second connecting line 220 extends in the row direction of the pixel unit 300, or the second connecting line 220 extends in the column direction of the pixel unit 300.

[0056] For example, refer to Figure 7 Multiple pixel units 300 are arranged in an array. Along a first direction X, the multiple pixel units 300 are arranged in a row. Along a second direction Y, the multiple pixel units 300 are arranged in a column. Along the second direction Y, one pixel unit 300 overlaps with a pixel unit 300 in an adjacent row. Optionally, two pixel units 300 are aligned in the second direction Y. Optionally, a similar arrangement can be used in the first direction X, which will not be described further here. In other embodiments, the multiple pixel units 300 may also have other arrangement methods.

[0057] For example, refer to Figure 7The first display area 110 includes a plurality of pixel units 300, and the arrangement of the pixel units 300 in the first display area 110 is the same as the arrangement in the second display area 120. In other embodiments, the arrangement of the pixel units 300 in the first display area 110 is different from the arrangement in the second display area 120.

[0058] For example, pixel unit 300 may include multiple sub-pixels. Connecting lines 200 (including first connecting line 210 and second connecting line 220) may pass through at least one sub-pixel. The sub-pixel located in the first display area 110 is the first sub-pixel, and the sub-pixel located in the second display area 120 is the second sub-pixel.

[0059] Figure 8 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 8 The first display area 110 includes a first sub-pixel 310. The first connecting line 210 includes a first sub-connecting line 211 and a second sub-connecting line 212. The first sub-connecting line 211 extends along a third direction J and passes through at least one first sub-pixel 310. The second sub-connecting line 212 extends along a fourth direction K and passes through at least one first sub-pixel 310. The third direction J and the fourth direction K intersect. In this embodiment of the invention, the first sub-connecting line 211 extends along the third direction J, and the second sub-connecting line 212 extends along the fourth direction K. Each first connecting line 210 is configured to extend along both the third direction J and the fourth direction K, which reduces the wiring difficulty. Overall, each first connecting line 210 is configured to radiate from the center, reducing the degree of misalignment of the connecting lines 200 at an oblique viewing angle.

[0060] For example, refer to Figure 1 and Figure 8 The first direction X intersects with both the third direction J and the fourth direction K, and the second direction Y intersects with both the third direction J and the fourth direction K. As an example, the angle between the first direction X and the third direction J is 45°, the angle between the second direction Y and the third direction J is 45°, the angle between the first direction X and the fourth direction K is 45°, and the angle between the second direction Y and the fourth direction K is 45°.

[0061] The first direction X is perpendicular to the second direction Y, and the third direction J is perpendicular to the fourth direction K.

[0062] Optionally, refer to Figure 8 The first sub-connecting line 211 and the second sub-connecting line 212 are connected to form a first connecting structure 410. In the first display area 110, a plurality of first connecting structures 410 are arranged from the area close to the center O of the first display area 110 toward the area away from the center O of the first display area 110.

[0063] For example, refer to Figure 8 Each first connection structure 410 passes through multiple first sub-pixels 310, and the multiple first connection structures 410 pass through all the first sub-pixels 310 in the first display area 110.

[0064] For example, refer to Figure 8 The first connecting structure 410 is V-shaped, with an included angle of 90°. The first connecting structure 410 includes two first connecting lines 210, each including a first sub-connecting line 211 and a second sub-connecting line 212. The first sub-connecting line 211 is perpendicular to the second sub-connecting line 212. It can be understood that, in this embodiment of the invention, the first display area 110 is divided into four regions: the region containing the first connecting structure 410 opening to the right, the region containing the first connecting structure 410 opening to the upper side, the region containing the first connecting structure 410 opening to the left, and the region containing the first connecting structure 410 opening to the lower side.

[0065] Figure 9 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 9 The first sub-connecting line 211 and the second sub-connecting line 212 are both located in the outer region 1102. The second connecting line 220 is located in the central region 1101. The second connecting line 220 extends along the first direction X, with one end of the second connecting line 220 connected to the first sub-connecting line 211 and the other end of the second connecting line 220 connected to the second sub-connecting line 212.

[0066] Figure 10 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 10 ,and Figure 9 The difference is that the second connecting line 220 extends along the second direction Y. The second connecting line 220 is connected to two first sub-connecting lines 211 and two second sub-connecting lines 212. In short, at least one end of the second connecting line 220 needs to be connected to at least one first connecting line 210.

[0067] Figure 11 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 11The first connecting line 210 includes a first sub-connecting line 211, a second sub-connecting line 212, a third sub-connecting line 213, and a fourth sub-connecting line 214. The first sub-connecting line 211 extends along a third direction J and passes through at least one first sub-pixel 310. The second sub-connecting line 212 extends along a fourth direction K and passes through at least one first sub-pixel 310. The third sub-connecting line 213 extends along a fifth direction L and passes through at least one first sub-pixel 310. The fourth sub-connecting line 214 extends along a sixth direction M and passes through at least one first sub-pixel 310. Any two of the third direction J, the fourth direction K, the fifth direction L, and the sixth direction M intersect. The second sub-connecting line 212 and the third sub-connecting line 213 are connected to form a second connecting structure 420. The third sub-connecting line 213 and the fourth sub-connecting line 214 are connected to form a third connecting structure 430. The fourth sub-connecting line 214 and the first sub-connecting line 211 are connected to form a fourth connecting structure 440. The multiple second connecting structures 420 are arranged from the region closest to the center O of the first display area 110 towards the region furthest from the center O of the first display area 110. The multiple third connecting structures 430 are arranged from the region closest to the center O of the first display area 110 towards the region furthest from the center O of the first display area 110. The multiple fourth connecting structures 440 are arranged from the region closest to the center O of the first display area 110 towards the region furthest from the center O of the first display area 110. In this embodiment of the invention, the first sub-connecting line 211 extends along the third direction J, the second sub-connecting line 212 extends along the fourth direction K, the third sub-connecting line 213 extends along the fifth direction L, and the fourth sub-connecting line 214 extends along the sixth direction M. Each first connecting line 210 is configured to extend along the third direction J, the fourth direction K, the fifth direction L, and the sixth direction M, which makes the extension direction of each first connecting line 210 closer to the radial direction of the first display area 110, thereby increasing the consistency between the extension direction of the first connecting line 210 and the direction of the increase in viewing angle, and reducing the degree of misalignment of the connecting line 200 under the tilted viewing angle.

[0068] For example, refer to Figure 1 and Figure 11 The first direction X is parallel to the third direction J, and the second direction Y is parallel to the fifth direction L. The first direction X intersects both the fourth direction K and the sixth direction M, and the second direction Y intersects both the fourth direction K and the sixth direction M. As an example, the angle between the third direction J and the fourth direction K is 45°, the angle between the fourth direction K and the fifth direction L is 45°, the angle between the fifth direction L and the sixth direction M is 45°, and the angle between the sixth direction M and the third direction J is 45°.

[0069] For example, refer to Figure 11Each first connection structure 410 passes through multiple first sub-pixels 310, each second connection structure 420 passes through multiple first sub-pixels 310, each third connection structure 430 passes through multiple first sub-pixels 310, and each fourth connection structure 440 passes through multiple first sub-pixels 310. The first connection structure 410, the second connection structure 420, the third connection structure 430, and the fourth connection structure 440 all pass through all the first sub-pixels 310 in the first display area 110.

[0070] For example, refer to Figure 11 The first connecting structure 410, the second connecting structure 420, the third connecting structure 430, and the fourth connecting structure 440 are all V-shaped, with an included angle of 45°. The first connecting structure 410 includes two first connecting lines 210, each including a first sub-connecting line 211 and a second sub-connecting line 212. The included angle between the first sub-connecting line 211 and the second sub-connecting line 212 is 45°. Similarly, the second connecting structure 420 includes a second sub-connecting line 212 and a third sub-connecting line 213, with an included angle of 45°. The third connecting structure 430 includes a third sub-connecting line 213 and a fourth sub-connecting line 214, with an included angle of 45°. The fourth connection structure 440 includes a fourth sub-connection line 214 and a first sub-connection line 211, with the included angle between the fourth sub-connection line 214 and the first sub-connection line 211 being 45°. It can be understood that, in this embodiment of the invention, the first display area 110 is divided into eight regions, namely, the region where the first connection structure 410 opens to the upper right, the region where the second connection structure 420 opens to the upper right, the region where the third connection structure 430 opens to the upper left, the region where the fourth connection structure 440 opens to the upper left, the region where the first connection structure 410 opens to the lower left, the region where the second connection structure 420 opens to the lower left, the region where the third connection structure 430 opens to the lower right, and the region where the fourth connection structure 440 opens to the lower right.

[0071] Figure 12 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 12The first sub-connecting line 211, the second sub-connecting line 212, the third sub-connecting line 213, and the fourth sub-connecting line 214 are all located in the outer region 1102. The second connecting line 220 is located in the central region 1101. The second connecting line 220 extends along the first direction X and is connected to at least one of the first sub-connecting lines 211, 212, 213, and 214, that is, at least one end of the second connecting line 220 needs to be connected to at least one first connecting line 210.

[0072] Optionally, refer to Figure 8 The first connecting line 210 includes a first type of connecting line 201 and a second type of connecting line 202. The distance between the end of the first type of connecting line 201 facing the center O of the first display area 110 and the center O of the first display area 110 is less than the distance between the end of the second type of connecting line 202 facing the center O of the first display area 110 and the center O of the first display area 110. That is, the first connecting line 210 with a shorter distance between its end and the center O of the first display area 110 is called the first type of connecting line 201, and the first connecting line 210 with a longer distance between its end and the center O of the first display area 110 is called the second type of connecting line 202. The number of first sub-pixels 310 traversed by the first type of connecting line 201 is greater than the number of first sub-pixels 310 traversed by the second type of connecting line 202. In this embodiment of the invention, the closer the end of the first connecting line 210 is to the center O of the first display area 110, the more first sub-pixels 310 it passes through; the farther the end of the first connecting line 210 is from the center O of the first display area 110, the fewer first sub-pixels 310 it passes through.

[0073] It should be noted that the present invention does not limit the arrangement of pixel units (including sub-pixels), as long as the first connecting line 210 passes through at least one first sub-pixel 310.

[0074] Figure 13 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 13The first display area 110 includes a first sub-pixel row 31 and a second sub-pixel row 32. Both the first sub-pixel row 31 and the second sub-pixel row 32 extend along a first direction X. Both the first sub-pixel row 31 and the second sub-pixel row 32 include a plurality of first sub-pixels 310. Along the second direction Y, adjacent first sub-pixel rows 31 are spaced apart by one second sub-pixel row 32, and adjacent second sub-pixel rows 32 are spaced apart by one first sub-pixel row 31. Along the second direction Y, the first sub-pixel rows 31 and the second sub-pixel rows 32 are arranged alternately. Each first sub-pixel 310 includes a first color sub-pixel 311, a second color sub-pixel 312, and a third color sub-pixel 313. Any two of the first color sub-pixel 311, the second color sub-pixel 312, and the third color sub-pixel 313 have different luminous colors. In the first sub-pixel row 31, a third-color sub-pixel 313 is spaced between two adjacent first-color sub-pixels 311, and a first-color sub-pixel 311 is spaced between two adjacent third-color sub-pixels 313. The first-color sub-pixels 311 and third-color sub-pixels 313 are arranged alternately. A first gap 51 exists between adjacent first-color sub-pixels 311 and third-color sub-pixels 313. The second sub-pixel row 32 includes a plurality of second-color sub-pixels 312. Along the second direction Y, the second-color sub-pixels 312 and the first gap 51 overlap.

[0075] For example, refer to Figure 13 Pixel unit 300 includes a first color sub-pixel 311, two second color sub-pixels 312, and a third color sub-pixel 313. Within the same pixel unit 300, the first color sub-pixel 311 and the third color sub-pixel 313 are located in the same first sub-pixel row 31, and the two second color sub-pixels 312 are located in the same second sub-pixel row 32. Color display is achieved by mixing light generated from the first color sub-pixels 311, second color sub-pixels 312, and third color sub-pixels 313 within the same pixel unit 300.

[0076] For example, refer to Figure 13 The pixel units 300 are arranged in the same way in the first display area 110 as they are in the second display area 120. The first sub-pixel 310 is arranged in the same way in the first display area 110 as the second sub-pixel 320 is in the second display area 120. Therefore, the first display area 110 and the second display area 120 have the same sub-pixel arrangement, which helps improve display consistency.

[0077] For example, refer to Figure 13 The first color sub-pixel 311 produces red light, the second color sub-pixel 312 produces green light, and the third color sub-pixel 313 produces blue light.

[0078] Figure 14This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 14 The first display area 110 includes multiple pixel unit rows 301, which extend along a first direction X. The multiple pixel unit rows 301 are arranged along a second direction Y. Each pixel unit row 301 includes multiple pixel units 300. In each pixel unit row 301, a second gap 52 exists between adjacent pixel units 300. Along the second direction Y, the pixel unit 300 overlaps with the second gap 52 in adjacent pixel unit rows 301. That is, the pixel units 300 in adjacent rows are arranged alternately. Each pixel unit 300 includes a first sub-pixel 310, which includes a first color sub-pixel 311, a second color sub-pixel 312, and a third color sub-pixel 313. Any two of the first color sub-pixel 311, the second color sub-pixel 312, and the third color sub-pixel 313 have different emission colors. In the same pixel unit 300, the first color sub-pixel 311, the third color sub-pixel 313, and the second color sub-pixel 312 are arranged along the first direction X. Along the first direction X, the third color sub-pixel 313 is located between the first color sub-pixel 311 and the second color sub-pixel 312. Within the same pixel unit 300, two second color sub-pixels 312 are arranged along the second direction Y. The arrangement of pixel units (including sub-pixels) provided in this embodiment of the invention is also applicable to the setting of the connecting line 200 in the above embodiments.

[0079] Figure 15 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 15 The first display area 110 includes a first sub-pixel 310. The first connecting line 210 includes a first sub-connecting line 211 and a second sub-connecting line 212. The first sub-connecting line 211 and the second sub-connecting line 212 are connected to form a first connecting structure 410. In the first display area 110, a plurality of first connecting structures 410 are arranged from the region near the center O of the first display area 110 toward the region away from the center O of the first display area 110. Each first connecting structure 410 passes through a plurality of first sub-pixels 310, and the plurality of first connecting structures 410 pass through all the first sub-pixels 310 in the first display area 110.

[0080] Figure 16 This is a top view of a portion of a display panel provided in another embodiment of the present invention, with reference to... Figure 16Both the first sub-connecting line 211 and the second sub-connecting line 212 are located in the outer region 1102. The second connecting line 220 is located in the central region 1101. The second connecting line 220 extends along the second direction Y, with one end of the second connecting line 220 connected to the first sub-connecting line 211 and the other end connected to the second sub-connecting line 212. One end of the second connecting line 220 is connected to both the first sub-connecting line 211 and the second sub-connecting line 212.

[0081] Figure 17 This is a top view schematic diagram of another first display area provided in an embodiment of the present invention, with reference to... Figure 17 The first display area 110 includes a plurality of first sub-pixel strings 302. Each first sub-pixel string 302 includes a plurality of first sub-pixels 310. The first sub-pixels 310 in each first sub-pixel string 302 are first sub-pixels 310 along the same first connecting line 210. The first connecting line 210 passes through all the first sub-pixels 310 in the first sub-pixel string 302. The extension line of the first sub-pixel string 302 passes through the center O of the first display area 110. In this embodiment of the invention, corresponding to the radial first connecting line 210, the arrangement of the first sub-pixels 310 in the first display area 110 is correspondingly set, and the first sub-pixel strings 302 formed by the plurality of first sub-pixels 310 are also arranged radially. Thus, the arrangement direction of the first sub-pixels 310 in the first sub-pixel string 302 and the extension direction of the first connecting line 210 are both radial directions of the first display area 110. The alignment of the arrangement direction of the first sub-pixels 310 in the first sub-pixel string 302 with the extension direction of the first connecting line 210 facilitates the radial arrangement of each first connecting line 210 through all the first sub-pixels 310 in the first display area 110. This ensures that the number of first sub-pixels 310 connected in series on each first connecting line 210 is as close as possible, avoiding load differences and improving display uniformity.

[0082] refer to Figure 17 The first sub-pixel string 302, formed by multiple first sub-pixels 310, is arranged radially. The first connecting line 210 is also radially arranged within the first display area 110, extending radially from the center O of the first display area 110 towards the center O further away from the center O. This arrangement aligns with the principle that the viewing angle increases with distance from the center O of the first display area. This reduces the misalignment of the connecting line 200 at tilted viewing angles. Furthermore, because the difference in the degree of offset between connecting lines 200 at different heights is small, there are no gaps between connecting lines 200 at different heights at tilted viewing angles, avoiding diffraction phenomena.

[0083] Optionally, refer to Figure 17 The first sub-pixel 310 includes a first color sub-pixel 311, a second color sub-pixel 312, and a third color sub-pixel 313, where any two of the first color sub-pixel 311, second color sub-pixel 312, and third color sub-pixel 313 have different emission colors. Within the same first sub-pixel string 302, the first color sub-pixel 311, second color sub-pixel 312, and third color sub-pixel 313 are arranged sequentially. Within the same first sub-pixel string 302, the second color sub-pixel 312 is located between the first color sub-pixel 311 and the third color sub-pixel 313, the third color sub-pixel 313 is located between the second color sub-pixel 312 and the first color sub-pixel 311, and the first color sub-pixel 311 is located between the third color sub-pixel 313 and the second color sub-pixel 312.

[0084] For example, refer to Figure 17 Multiple first sub-pixels 310, located at the same distance from the center O of the first display area 110, are situated on the same pixel ring 303. First color sub-pixels 311 and second color sub-pixels 312 are situated on two different pixel rings 303, as are second color sub-pixels 312 and third color sub-pixels 313.

[0085] Figure 18 This is a top view schematic diagram of another first display area provided in an embodiment of the present invention, with reference to... Figure 18 Multiple first sub-pixels 310, located at the same distance from the center O of the first display area 110, are situated on the same pixel ring 303. Within the same pixel ring 303, first-color sub-pixels 311, second-color sub-pixels 312, and third-color sub-pixels 313 are arranged sequentially. This arrangement ensures that, along the radial direction of the first display area 110, the first-color sub-pixels 311, second-color sub-pixels 312, and third-color sub-pixels 313 within the same first sub-pixel string 302 are approximately arranged sequentially. The distribution of the first-color sub-pixels 311, second-color sub-pixels 312, and third-color sub-pixels 313 along the radial direction of the first display area 110 is also relatively uniform, rather than having only one color of first sub-pixels 310. Therefore, this seed pixel arrangement helps improve the display uniformity of the first display area 110.

[0086] Optionally, refer to Figure 17 and Figure 18The number of first sub-pixel strings 302 overlapping with the pixel ring 303 gradually increases from the region near the center O of the first display area 110 towards the region away from the center O of the first display area 110. In this embodiment of the invention, from the inside out, the further outward one goes, the more numerous the first sub-pixel strings 302 and the more numerous the first sub-pixels 310 become, thereby improving the overall distribution uniformity of the first sub-pixels 310 in the first display area 110 and improving the display uniformity of the first display area 110.

[0087] Optionally, refer to Figure 17 and Figure 18 The first connecting line 210 includes a first type of connecting line 201 and a second type of connecting line 202. The distance between the end of the first type of connecting line 201 facing the center O of the first display area 110 and the center O of the first display area 110 is less than the distance between the end of the second type of connecting line 202 facing the center O of the first display area 110 and the center O of the first display area 110. In this embodiment of the invention, the closer the end of the first connecting line 210 is to the center O of the first display area 110, the more first sub-pixels 310 it passes through; the farther the end of the first connecting line 210 is from the center O of the first display area 110, the fewer first sub-pixels 310 it passes through.

[0088] For example, refer to Figure 17 and Figure 18 The arrangement of the first connecting lines 210, which string together different numbers of first sub-pixels 310, can be periodic. The arrangement direction of each first connecting line 210 is circumferential, surrounding the center O of the first display area 110. The first connecting lines 210 include first-type connecting lines, second-type connecting lines, ..., Nth-type connecting lines. The first-type connecting lines, second-type connecting lines, ..., Nth-type connecting lines are arranged alternately and cyclically in sequence. In this way, the traces with different loads can be evenly distributed, improving the display uniformity of the display panel.

[0089] Figure 19 This is a top view of a portion of a display panel provided in an embodiment of the present invention. Figure 20 for Figure 19 A top-view structural diagram of the S2 region. Figure 21 For along Figure 19 A schematic diagram of the cross-sectional structure of AA' is shown in the reference diagram. Figures 19-21 The display panel also includes a substrate 610. Connecting lines 200 are located on one side of the substrate 610. A first sub-pixel 310 includes a cathode block 331. Connecting lines 200 include cathode interconnects 611, which are electrically connected to the cathode block 331.

[0090] For example, refer to Figures 19-21The cathode interconnect 611 and the cathode block 331 are electrically connected in the same layer. The cathode interconnect 611 and the cathode block 331 can be made of the same material and formed in the same process, thereby saving process steps. Both the cathode interconnect 611 and the cathode block 331 are made of silver alloy, and both the cathode interconnect 611 and the cathode block 331 are configured to be semi-transparent in the visible light band.

[0091] It should be noted that the reference Figure 20 The cathode connecting line 611 is electrically connected to the cathode block 331 on the same layer, and the cathode connecting line 611 connects the two cathode blocks 331. It can be understood that the cathode connecting line 611 and a part of the cathode block 331 that are electrically connected in the same direction of extension can be regarded as the connecting line 200.

[0092] Optionally, refer to Figures 19-21 The connecting line 200 also includes a light-shielding layer 612, which is located between the cathode connecting line 611 and the substrate 610. The light-shielding layer 612 overlaps with the cathode connecting line 611 in a direction perpendicular to the substrate 610. In known technologies, the connecting line 200 includes a cathode connecting line 611 and a light-shielding layer 612, which overlap in a direction perpendicular to the substrate 610. At an oblique viewing angle, both the cathode connecting line 611 and the light-shielding layer 612 are misaligned. Since the cathode connecting line 611 and the light-shielding layer 612 are located in two different film layers, the interlacing of the projections of the different film layers increases the overall light-shielding area. In this embodiment of the invention, by setting the cathode connection 611 and the light-shielding layer 612 to extend from the area near the center O of the first display area 110 toward the area away from the center O of the first display area 110, the degree of misalignment of the cathode connection 611 and the light-shielding layer 612 under the tilted viewing angle is reduced, the overall light-shielding area is reduced, and the transmittance of the first display area 110 is increased.

[0093] For example, the light-shielding layer 612 is configured to be opaque in the visible light band.

[0094] Optionally, refer to Figures 19-21 The cathode interconnect 611 and cathode block 331 are formed by using a light-shielding layer 612 as a mask and irradiating the entire cathode layer with a laser. After the entire cathode layer is formed, the entire cathode layer can be irradiated with a laser from the back of the display panel, from the side of the substrate 610. The cathode layer not blocked by the light-shielding layer 612 is removed by the laser irradiation, while the cathode layer blocked by the light-shielding layer 612 cannot be irradiated by the laser and is retained, thus forming the cathode interconnect 611 and cathode block 331.

[0095] Optionally, refer to Figure 21The second display area 120 includes a pixel driving circuit 620, which is located between the substrate 610 and the film layer containing the cathode connection 611. A light-shielding layer 612 is located between the film layer containing the pixel driving circuit 620 and the substrate 610. Therefore, as an independent new film layer, the thickness of the light-shielding layer 612 is relatively easy to set; that is, an independent thickness can be set for the light-shielding layer 612. Typically, the thickness of the light-shielding layer 612 can be greater than the thickness of a single metal layer in the pixel driving circuit 620 to facilitate the blocking of high-energy laser light. In other embodiments, the light-shielding layer 612 can also be co-layered with the metal layer in the pixel driving circuit 620 and formed using the same material in the same process, thereby saving process steps.

[0096] For example, refer to Figure 21 The pixel driving circuit 620 includes thin-film transistors. The pixel driving circuit 620 may include multiple thin-film transistors and at least one storage capacitor. This embodiment of the invention does not limit the specific circuit structure of the pixel driving circuit.

[0097] Figure 22 This is a top view of a portion of a display panel provided in an embodiment of the present invention. Figure 23 For along Figure 22 A schematic diagram of the cross-sectional structure of BB' (see reference). Figure 22 and Figure 23 The connecting line 200 also includes an anti-reflection layer 613, which is located on the side of the cathode connecting line 611 away from the substrate 610. The anti-reflection layer 613 overlaps with the cathode connecting line 611 in a direction perpendicular to the substrate 610. In known technologies, the connecting line 200 includes a cathode connecting line 611 and an anti-reflection layer 613, which overlap in a direction perpendicular to the substrate 610. At an oblique viewing angle, both the cathode connecting line 611 and the anti-reflection layer 613 are misaligned. Since the cathode connecting line 611 and the anti-reflection layer 613 are located in two different film layers, the interlacing of the projections of the different film layers increases the overall light-shielding area. In this embodiment of the invention, by setting the cathode connection 611 and the anti-reflection layer 613 to extend from the region near the center O of the first display area 110 toward the region away from the center O of the first display area 110, the degree of misalignment of the cathode connection 611 and the anti-reflection layer 613 under the tilted viewing angle is reduced, the overall light-blocking area is reduced, and the transmittance of the first display area 110 is increased.

[0098] For example, the antireflective layer 613 is configured to be translucent or opaque in the visible light band.

[0099] For example, refer to Figure 22 and Figure 23The connecting line 200 includes a cathode connecting line 611, a light-shielding layer 612, and an anti-reflection layer 613, and is perpendicular to the substrate 610. Any two of the cathode connecting line 611, the light-shielding layer 612, and the anti-reflection layer 613 overlap. In this embodiment of the invention, by setting the cathode connecting line 611, the light-shielding layer 612, and the anti-reflection layer 613 to extend from the region near the center O of the first display area 110 toward the region away from the center O of the first display area 110, the degree of misalignment of the cathode connecting line 611, the light-shielding layer 612, and the anti-reflection layer 613 at the tilted viewing angle is reduced, the overall light-shielding area is reduced, and the transmittance of the first display area 110 is increased.

[0100] Optionally, refer to Figure 22 and Figure 23 The anti-reflection layer 613 includes black matrix connecting lines 711, and the black matrix connecting lines 711 include light-absorbing material.

[0101] For example, refer to Figure 22 and Figure 23 The display panel also includes a black matrix layer 712 and a color resist 72. The black matrix layer 712 is located in the second display area 120. The black matrix layer 712 has multiple openings. The color resist 72 is located on the side of the film layer containing the cathode interconnect 611 away from the substrate 610. In the first display area 110, in a direction perpendicular to the substrate 610, the color resist 72 overlaps with the first sub-pixel 310. In the second display area 120, in a direction perpendicular to the substrate 610, the color resist 72 overlaps with the second sub-pixel 320, and the color resist 72 is located in the openings formed by the black matrix layer 712.

[0102] Figure 24 This is a top view of a portion of a display panel provided in an embodiment of the present invention. Figure 25 For along Figure 24 A cross-sectional structural diagram of CC' (see reference). Figure 24 and Figure 25 The antireflection layer 613 includes a polarizer connecting line 731, which includes a polarizing material configured to alter the polarization state of light passing through it. Light passing through the polarizer connecting line 731 experiences reduced brightness because at least some of its polarized states are blocked.

[0103] For example, refer to Figure 24 and Figure 25 The display panel also includes a polarizer layer 732, which is located in the second display area 120. In the second display area 120, the polarizer layer 732 is disposed in a single layer, covering a plurality of second sub-pixels 320.

[0104] Optionally, refer to Figures 19-25The second display area 120 includes a second sub-pixel 320. All second sub-pixels 320 share the same cathode layer 321, and cathode interconnect 611 is electrically connected to cathode layer 321, thereby cathode interconnect 611 and cathode layer 321 have the same common potential.

[0105] For example, refer to Figure 2 as well as Figures 19-25 The first connecting line 210 is located in the first display area 110, and the first connecting line 210 can be connected to a structure in the second display area 120. For example... Figure 19 As shown, when the first connecting line 210 includes a cathode connecting line 611, the cathode connecting line 611 is connected to the cathode layer 321 in the second display area 120. Figure 22 As shown, when the first connecting line 210 includes the black matrix connecting line 711, the black matrix connecting line 711 is connected to the black matrix layer 712 in the second display area 120. For example... Figure 24 As shown, the first connection line 210 includes a polarizer connection line 731, which is connected to the polarizer layer 732 in the second display area 120.

[0106] For example, refer to Figure 2 as well as Figures 19-25 The first connecting line 210 is located in the first display area 110, and the first connecting line 210 may not be connected to any structure in the second display area 120. For example... Figure 21 As shown, the first connecting line 210 includes a light-shielding layer 612, which serves as a mask when the laser irradiates the first display area 110. Since the laser does not irradiate the second display area 120, no structure at the same layer as the light-shielding layer 612 is provided in the second display area 120. Therefore, the light-shielding layer 612 may not be connected to any structure in the second display area 120.

[0107] Figure 26 This is a top view schematic diagram of another display panel provided in an embodiment of the present invention. Figure 27 For along Figure 26 A schematic diagram of the cross-sectional structure of DD' (see reference). Figure 26 and Figure 27The display area 100 also includes a transition area 130, which is located between the first display area 110 and the second display area 120. As an example, the transition area 130 is located around the first display area 110. The second display area 120 is located around the transition area 130. The first sub-pixel 310 also includes an anode 333. The transition area 130 includes a pixel driving circuit 620, which is electrically connected to the anode 333 and provides a driving voltage and / or driving current to the anode 333. In this embodiment of the invention, the pixel driving circuit 620 for driving the first sub-pixel 310 in the first display area 110 is disposed in the transition area 130, so that the pixel driving circuit 620 does not occupy the space of the first display area 110, increasing the transmittance of the first display area 110.

[0108] For example, refer to Figure 27 The first sub-pixel 310 also includes a light-emitting functional layer 332. In the first sub-pixel 310, perpendicular to the substrate 610, the light-emitting functional layer 332 is located between the anode 333 and the cathode block 331. The second sub-pixel 320 also includes a light-emitting functional layer 332 and an anode 333. In the second sub-pixel 320, perpendicular to the substrate 610, the light-emitting functional layer 332 is located between the anode 333 and the cathode layer 321.

[0109] For example, refer to Figure 27 The display panel also includes a transparent electrode connection line 80, which is transparent in the visible light band. One end of the transparent electrode connection line 80 is electrically connected to the anode 333 of the first sub-pixel 310 in the first display area 110, and the other end of the transparent electrode connection line 80 is electrically connected to the pixel driving circuit 620 in the transition area 130. Because the transparent electrode connection line 80 is transparent in the visible light band, the transparent electrode connection line 80 located in the first display area 110 will not reduce the transmittance of the first display area 110.

[0110] Figure 28 This is a cross-sectional structural diagram of a display device provided in an embodiment of the present invention, with reference to... Figure 28 The display device includes a display panel 91 and a light sensor 92. The light sensor 92 is located in the first display area 110, on the non-light-emitting side of the display panel 91. Ambient light passes through the first display area 110 of the display panel 91 and reaches the light sensor 92 located on the back of the display panel 91, thereby achieving specific optical performance, such as imaging.

[0111] in, Figure 28 The direction of the middle arrow indicates the light emission direction of the display panel 91. The display device can specifically be a mobile phone, tablet computer, or smart wearable device, etc.
