Display panel and display device

Abstract

This application discloses a display panel and display device, belonging to the field of display technology. By setting the orthographic projections of the first touch trace portion and the second touch trace portion of the same touch trace in the first area within the visible area on the substrate to be at least partially staggered, at least a portion of the orthographic projection of each second touch trace portion in the first area within the visible area on the first touch layer is located in the gap between two adjacent first touch trace portions. This allows light emitted through the gap between two adjacent first touch trace portions in the first touch layer within the visible area to be reflected by at least a portion of the second touch trace portion above it, thereby reducing the amount of light emitted through the first area within the visible area. This avoids uneven brightness in the visible area due to the different densities of multiple touch traces in different areas of the first area within the visible area, thus improving the display quality of the display panel.

[0006] Optionally, the plurality of touch traces include a first touch trace and a second touch trace that are adjacent to each other and spaced apart. One side of the second touch trace portion of the first touch trace and one side of the first touch trace portion of the second touch trace are projected onto the substrate, and the projected onto the substrate of the second touch trace portion of the first touch trace and the first touch trace portion of the second touch trace are completely offset.

[0008] Optionally, the plurality of touch traces include a first touch trace, a second touch trace, and a third touch trace arranged sequentially along a first direction. The second touch trace portion of the first touch trace is spaced apart from the second touch trace portion of the second touch trace along the first direction by a distance of S1, and the first touch trace portion of the second touch trace is spaced apart from the first touch trace portion of the third touch trace along the first direction by a distance of S2.

The first direction and the second direction are intersecting. The first area includes a first routing area and a second routing area located within the first straight area or the second straight area. The first routing area is closer to the corner area than the second routing area. The number of touch traces in the first routing area is greater than the number of touch traces in the second routing area, and the width of the touch traces in the first routing area is less than the width of the touch traces in the second routing area.

[0010] Optionally, it further includes an encapsulation layer, wherein the touch layer is located on the side of the encapsulation layer opposite to the substrate; the first region further includes a second insulating layer located between the first touch layer and the encapsulation layer.

This allows light emitted through the gap between two adjacent first touch trace portions in the first touch layer within the visible region to be reflected by at least a portion of the second touch trace portion located above it, thereby reducing the amount of light emitted through the first area within the visible region. This prevents uneven brightness in the visible region due to the different densities of multiple touch traces in different areas of the first area within the visible region, thus improving the display quality of the display panel.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] In related technologies, the substrate of a capacitive touch display panel includes a display area, an ink area, and a visible area located between the display area and the ink area. There are a large number of touch traces in the visible area. The dense arrangement of these touch traces in the visible area causes uneven brightness in the visible area located at the edge of the display area.

[0023] This application provides a display panel 100, which includes a capacitive touch display panel. The display panel 100 is applicable to small and medium-sized capacitive touch display devices, including portable devices such as smartphones and smartwatches.

[0024] like Figures 1 to 3As shown, the display panel 100 has a display area 11, an ink area 12, and a viewable area 13, with the viewable area 13 located between the ink area 12 and the display area 11. The display area 11 includes multiple sub-pixels and is used to display images. The ink area 12 is correspondingly provided with an ink layer 6 to shield non-display elements surrounding the display area 11 from light. The ink layer 6 (e.g., ...) Figure 5 (As shown) includes light-shielding ink. A visible area 13 is provided between the display area 11 and the ink area 12 as a buffer to prevent ink from the ink area 12 from intruding into the display area 11, thereby causing incomplete image display in the display area 11.

[0025] The visible area 13 serves as a blank transition zone to connect the display area 11 and the ink area 12. As an example, the visible area 13 surrounds the display area 11, and the ink area 12 surrounds the visible area 13. The surface area of ​​the visible area 13 is significantly smaller than the surface area of ​​the display area 11, and the surface area of ​​the ink area 12 is significantly smaller than the surface area of ​​the display area 11. Alternatively, when the ink area 12 is configured to partially surround the display area 11, for example, when the ink area 12 is located only on one, two, or three of the bottom, top, left, and right sides of the display area 11, the visible area 13 is correspondingly configured to be located on one, two, or three of the bottom, top, left, and right sides of the display area 11. The display area 11 has a bottom and a top opposite each other along its length direction y, and the display area 11 also has a left and a right side opposite each other along its width direction x.

[0026] The display area 11 is equipped with multiple touch electrodes and multiple receiving electrodes to form an electric field for capacitive touch.

[0027] like Figure 4 and Figure 6 As shown, the display panel 100 includes a substrate 1 and a touch layer 2, with the touch layer 2 located on one side of the substrate 1.

[0028] The substrate 1 serves as a support substrate and can be either a rigid glass substrate or a flexible polyimide film substrate.

[0029] like Figures 2 to 4 As shown, the touch layer 2 includes multiple touch traces 3, which extend within the ink area 12 and the visible area 13 and connect to multiple touch electrodes and multiple receiving electrodes. In some embodiments, the arrangement of the multiple touch traces 3 within the visible area 13 is substantially the same as their arrangement within the ink area 12, i.e., each touch trace 3 extends from the ink area 12 into the visible area 13 in the same direction, thereby simplifying the structure of the touch layer 2 and facilitating its fabrication.

[0030] like Figure 5 and Figure 7As shown, the touch layer 2 includes a first area 21A and a second area 21B, wherein the first area 21A is located within the visible area 13, and the second area 21B is located within the ink area 12 and is blocked by the ink layer 6 so that light is difficult to escape from the second area 21B.

[0031] The first region 21A includes a first touch layer 211 and a second touch layer 212 stacked along the thickness direction z of the display panel 100, and a first insulating layer 221 located between the first touch layer 211 and the second touch layer 212. The first insulating layer 221 is used to provide interlayer insulation between the first touch layer 211 and the second touch layer 212.

[0032] The embodiments of this application specifically illustrate the stacked arrangement structure of multiple touch traces 3 within the visible area 13. For example... Figures 4 to 7 As shown, as an example, the first area 21A located within the visible area 13 includes a first touch layer 211 and a second touch layer 212. The first touch layer 211 includes a plurality of first touch traces 231 spaced apart along a first direction, and the second touch layer 212 includes a plurality of second touch traces 232 spaced apart along the first direction, wherein each second touch trace 232 corresponds to one first touch trace 231. That is, the number of first touch traces 231 in the first touch layer 211 is the same as the number of second touch traces 232 in the second touch layer 212. The first direction can be the width direction x of the display panel 100.

[0033] The same touch trace 3 includes a first touch trace portion 231 located in the first touch layer 211 and a second touch trace portion 232 located in the second touch layer 212. Along the thickness direction z of the display panel 100, the orthographic projections of the first touch trace portion 231 and the second touch trace portion 232 of the same touch trace 3 on the substrate 1 are set to be at least partially offset.

[0034] Understandably, since the same touch trace 3 includes a first touch trace portion 231 located on the first touch layer 211 and a second touch trace portion 232 located on the second touch layer 212 in the first area 21A of the visible area 13, and the orthographic projections of the first touch trace portion 231 and the second touch trace portion 232 of the same touch trace 3 on the substrate 1 are set to be at least partially offset, therefore at least a portion of the orthographic projection of the second touch trace portion 232 of each second touch layer 212 located in the first area 21A of the visible area 13 on the first touch layer 211 is at least partially offset. In the interval between two adjacent first touch traces 231, light emitted from the interval between two adjacent first touch traces 231 of the first touch layer 211 in the visible area 13 is reflected by at least a portion of the second touch trace 232 located above it, thereby reducing the amount of light emitted through the first area 21A in the visible area 13. This prevents uneven brightness in the visible area 13 due to the different densities of multiple touch traces in different areas of the first area 21A in the visible area 13, thus improving the display quality of the display panel 100.

[0035] For example, Figure 4 and Figure 5 As shown, the number of touch traces 3 in the first area 21A within the visible area 13 is relatively large, correspondingly resulting in a large number of first touch trace portions 231 in the first touch layer 211 and a large number of second touch trace portions 232 in the second touch layer 212, thus increasing the spacing between the multiple first touch trace portions 231. Figure 6 and Figure 7 As shown, the number of touch traces 3 in the second area 21B within the visible area 13 is relatively small. Correspondingly, the number of multiple first touch trace portions 231 in the first touch layer 211 and the number of multiple second touch trace portions 232 in the second touch layer 212 are also relatively small, resulting in a smaller spacing between the multiple first touch trace portions 231. It is understandable that if the second touch trace portions 232 do not block the spacing between adjacent first touch trace portions 231, a large amount of light will be obstructed. Figure 4 and Figure 5 The light emitted from the first region 21A shown, while a small amount of light was emitted from areas such as... Figure 5 and Figure 6 The light emitted from the first region 21A shown causes uneven brightness in the first region 21A at different positions within the visible area 13.

[0036] In some embodiments, continue to refer to Figures 4 to 7Multiple touch traces 3 include adjacent and spaced first touch traces 31 and second touch traces 32. The right side of the second touch trace portion 232 of the first touch trace 31 located in the visible area 13 and the left side of the first touch trace portion 231 of the second touch trace 32 located in the visible area 13 are projected onto the substrate 1, and the projected onto the substrate 1 of the second touch trace portion 232 of the first touch trace 31 and the first touch trace portion 231 of the second touch trace 32 are completely offset.

[0037] Understandably, the first touch trace 31 and the second touch trace 32 can be different touch signal lines. When the orthographic projections of the second touch trace portion 232 of the first touch trace 31 and the first touch trace portion 231 of the second touch trace 32 on the substrate 1 partially overlap, signal interference will occur, thereby affecting the display quality of the display panel 100. By setting the orthographic projections of the second touch trace portion 232 of the first touch trace 31 and the first touch trace portion 231 of the second touch trace 32 on the substrate 1 to be completely staggered, signal interference can be avoided. Meanwhile, the right side of the second touch line portion 232 of the first touch line 31 and the left side of the first touch line portion 231 of the second touch line 32 are projected onto the substrate 1 to coincide with each other. That is, the right side of the second touch line portion 232 of the first touch line 31 and the left side of the first touch line portion 231 of the second touch line 32 are vertically aligned, so that the light emitted through the gap between the first touch line portion 231 of the first touch line 31 and the first touch line portion 231 of the second touch line 32 is completely reflected by the second touch line portion 232 of the first touch line 31 without light leakage.

[0038] In some embodiments, the width of the second touch trace portion 232 of the first touch trace 31 located in the visible area 13 extending along the length or width direction of the display panel 100 is w, and the distance between the first touch trace portion 231 of the first touch trace 31 and the first touch trace portion 231 of the second touch trace 32 along the length or width direction of the display panel 100 is d, wherein w > d.

[0039] By setting the width w of the second touch line portion 232 located within the visible area 13 of the first touch line 31 to be greater than the interval d between the first touch line portion 231 of the first touch line 31 and the first touch line portion 231 of the second touch line 32, the light emitted through the interval between the first touch line portion 231 of the first touch line 31 and the first touch line portion 231 of the second touch line 32 is completely reflected by the first touch line portion 231 located above it, thereby preventing light from being emitted through the first area 21A within the visible area 13. This also prevents uneven brightness in the visible area 13 due to the different densities of multiple touch lines in different areas of the first area 21A within the visible area 13, thus improving the display quality of the display panel 100.

[0040] In some embodiments, the plurality of touch traces 3 include a first touch trace 31, a second touch trace 32, and a third touch trace 33 arranged sequentially along the width direction of the display panel 100. The interval between the second touch trace portion 232 of the first touch trace 31 and the second touch trace portion 232 of the second touch trace 32 along the width direction of the display panel 100 is S1, and the interval between the first touch trace portion 231 of the second touch trace 32 and the first touch trace portion 231 of the third touch trace 33 along the width direction of the display panel is S2. The width of the first touch trace portion 231 of the first touch trace 31 is w1, and the width of the first touch trace portion 231 of the second touch trace 32 is w2, wherein w2≥S1 and w2≤w1+S1-S2.

[0041] By setting the width w2 of the first touch trace portion 231 of the second touch trace 32 to be greater than S1, and setting the width w2 of the first touch trace portion 231 of the second touch trace 32 to be less than the sum of the width w1 of the first touch trace portion 231 of the first touch trace 32 and S1-S2, the width w2 of the first touch trace portion 231 of the second touch trace 32 has a suitable range, under the premise that S1 and S2 have a minimum spacing based on the process requirements. This avoids the situation where the width w2 of the first touch trace portion 231 of the second touch trace 32 is too large. This causes the first touch trace portion 231 of the third touch trace 33 to move to the right, which in turn causes the right side of the second touch trace portion 232 of the second touch trace 32 and the left side of the first touch trace portion 231 of the third touch trace 33 to be misaligned along the thickness direction of the display panel. As a result, light is emitted through the gap between the right side of the second touch trace portion 232 of the second touch trace 32 and the left side of the first touch trace portion 231 of the third touch trace 33, and the uneven density of the touch traces in different gaps causes uneven brightness in the visible area 13.

[0042] In some embodiments, the distance between the second touch trace portion 232 of the first touch trace 31 and the second touch trace portion 232 of the second touch trace 32 along the width direction of the display panel 100 is S1, and the distance between the first touch trace portion 231 of the second touch trace 32 and the first touch trace portion 231 of the third touch trace 33 along the width direction of the display panel is S2, wherein S1 may be equal to S2 or may not be equal to S2.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the visible area 13 of the display panel 100 includes a first straight area 131, a second straight area 132, and a corner area 133 connecting the first straight area 131 and the second straight area 132. The first straight area 131 is located on one side of the visible area 13 in a first direction, and the second straight area 132 is located on one side of the visible area 13 in a second direction. The first and second directions are intersected. As an example, the first straight area 131 may be located on the left or right side of the visible area 13, and the second straight area 132 may be located above or below the visible area 13.

[0044] The first area 21A located in the visible area 13 includes a first wiring area 241 and a second wiring area 242. The first wiring area 241 and the second wiring area 242 are located in the first straight area 131 or the second straight area 132. The first wiring area 241 is closer to the corner area 133 of the visible area 13 than the second wiring area 242. The number of touch wiring lines 3 in the first wiring area 241 is greater than the number of touch wiring lines 3 in the second wiring area 242. The width of the touch wiring lines 3 in the first wiring area 241 is smaller than the width of the touch wiring lines 3 in the second wiring area 242.

[0045] Understandably, the multiple touch traces 3 include multiple driving electrode traces and multiple receiving electrode traces. When multiple driving electrode traces and multiple receiving electrode traces are simultaneously provided in the first trace area 241, while only one of the multiple driving electrode traces and multiple receiving electrode traces is provided in the second trace area 242, in order to keep the trace resistance of the first trace area 241 and the second trace area 242 close, the line width of each touch trace 3 in the first trace area 241 is set to be smaller than the line width of each touch trace 3 in the second trace area 242, so as to improve the signal-to-noise ratio and response speed.

[0046] In some embodiments, a plurality of first wiring areas 241 and a plurality of second wiring areas 242 are provided on the same side of the display area 11. The same side may be the bottom, left, or right side of the display area 11.

[0047] In some embodiments, the display panel 100 further includes an encapsulation layer 4, with a touch layer 2 located on the side of the encapsulation layer 4 facing away from the substrate 1, and the touch layer 2 disposed on top of the encapsulation layer 4. The encapsulation layer 4 is configured to prevent water and oxygen molecules from penetrating into the touch layer. The encapsulation layer 4 may include at least one inorganic layer and at least one organic layer, wherein the material of the inorganic layer includes at least one of silicon nitride, aluminum oxide, and silicon oxide. The material of the organic layer includes at least one of acrylate and epoxy resin. As an example, the encapsulation layer 4 includes a first inorganic layer, an organic layer disposed on the side of the first inorganic layer facing away from the substrate 1, and a second inorganic layer disposed on the side of the organic layer facing away from the first inorganic layer.

[0048] In some embodiments, a second insulating layer 222 is further provided between the encapsulation layer 4 and the first touch layer 211 of the first region 21A, the second insulating layer 222 being used to provide electrical insulation between the first touch layer 211 and the encapsulation layer 4.

[0049] In some embodiments, the display panel 100 further includes a backplate 5, which is located on the side of the encapsulation layer 4 opposite to the touch layer 2. The backplate 5 includes a thin-film transistor array. The backplate 5 is configured to extend within the display area 11, the visible area 13, and the ink area 12. Light emitted from the display area 11 is reflected by the backplate 5 and enters the first area 21A of the visible area 13. Since the multiple first touch traces 231 of the first touch layer 211 of the first area 21A form multiple intervals, and each interval is provided with a corresponding second touch trace 232, the light is reflected by the touch traces of the second touch trace 232 and cannot continue to be emitted, thereby reducing the problem of uneven brightness in the area where the first area 21A is located.

[0050] In some embodiments, the display panel 100 includes an ink layer 6 disposed on a cover plate located above the touch layer 2, the ink layer 6 being disposed only in relation to the ink area 12.

[0051] In some embodiments, such as Figure 7 and Figure 8 As shown, the second region 21B is located within the ink region 12 and is blocked by the ink layer 6. Therefore, the multiple touch traces 3 of the second region 21B located inside the ink region 12 are completely blocked by the ink layer 6, and no light leakage occurs.

[0052] In some embodiments, such as Figure 8As shown, the second region 21B includes a third touch layer 213 and a fourth touch layer 214 stacked together. The same touch trace 3 includes a third touch trace portion 233 located in the third touch layer 213 and a fourth touch trace portion 234 located in the fourth touch layer 214. Along the thickness direction of the display panel 100, the orthographic projections of the third touch trace portion 233 and the fourth touch trace portion 234 of the same touch trace 3 onto the substrate 1 can be either completely overlapping or partially offset. When the orthographic projections of the third touch trace portion 233 and the fourth touch trace portion 234 of the same touch trace 3 onto the substrate 1 are partially offset, that is, the structures of the first region 21A and the second region 21B can be identical, which is beneficial for processing and molding.

[0053] In some embodiments, continue to refer to Figure 6 and Figure 8 As shown, the staggered interval between the orthographic projections of the third touch trace portion 233 and the fourth touch trace portion 234 of the same touch trace 3 on the substrate 1 is set to L1, and the staggered interval between the orthographic projections of the first touch trace portion 231 and the second touch trace portion 232 of the same touch trace 3 on the substrate 1 is set to L2, where L1≤L2. The staggered interval L1 between the third touch trace portion 233 and the fourth touch trace portion 234 of the same touch trace 3 in the second area 21B located inside the ink area 12 is small, so as to make good use of the light-shielding performance of the ink area 12 to arrange more touch traces 3 in the second area 21B. On the other hand, the staggered interval L2 between the first touch trace portion 231 and the second touch trace portion 232 of the same touch trace 3 in the first area 21A located in the visible area 13 is large, so that the second touch trace portion 232 can fully block the gap between two adjacent first touch trace portions 231 to avoid uneven brightness in the visible area 13 and improve the display quality.

[0054] It should be noted that, since ink layer 6 is provided corresponding to ink area 12, the multiple touch traces 3 located in the second area 21B inside ink area 12 are completely blocked by ink layer 6, and no light leakage occurs. Therefore, the same touch trace 3 can be aligned with the third touch layer 213 and the fourth touch layer 214 in ink area 12, i.e., L2=0. Furthermore, the alignment of the same touch trace 3 with the third touch layer 213 and the fourth touch layer 214 in ink area 12 can improve the integrity of touch trace signals, reduce delay and crosstalk, and simplify the manufacturing process of the third touch layer 213 and the fourth touch layer 214, thereby improving yield and reliability.

[0055] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
