Description

Display panel, manufacturing method thereof, and display device Technical Field

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

[0002] Currently, flexible touch screens are created using a flexible mesh layer on cell (FMLOC). These displays include a touch layer integrated onto a flexible display substrate, protected by an organic layer on top. For OLED (Organic Light-Emitting Diode) touch screens, signal lines, such as data lines, are typically densely arranged in the periphery. Since these signal lines are made of metal, when strong light strikes the display panel, these densely arranged signal lines can easily reflect light, affecting display quality.

DETAILED DESCRIPTION

[0092] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0093] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0094] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0095] A transistor is a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (drain electrode terminal, drain region, or drain electrode) and a source electrode (source electrode terminal, source region, or source electrode), through which current can flow. The channel region is the area where current primarily flows.

[0096] The first electrode can be a drain electrode and the second electrode can be a source electrode, or vice versa. The functions of "source electrode" and "drain electrode" may be interchanged when using transistors with opposite polarity or when the direction of current changes during circuit operation. Therefore, in this specification, "source electrode" and "drain electrode" may be interchanged.

[0097] In related technologies, a display panel includes a base substrate and multiple sub-pixels and signal lines arranged on one side of the base substrate. The signal lines are used to connect the sub-pixels to peripheral chips, etc., to control the operating status of each sub-pixel. A display panel consists of a display area and a peripheral area. Signal lines are typically densely arranged in the peripheral area. Since the signal lines are made of metal, when strong light shines on the display panel, the densely arranged signal lines in the periphery are prone to light reflection, thereby affecting display quality.

[0098] As shown in Figures 1, 2, 5, 7, 25 and 26, a display panel is provided in an embodiment of the present disclosure, including a base substrate 100, a signal line layer 200 and a touch layer 300, wherein the base substrate 100 includes a display area 110 and a non-display area 120; the signal line layer 200 is provided on one side of the base substrate 100, the signal line layer 200 includes a plurality of signal lines 210, and the signal lines 210 are at least partially located in the non-display area 120; the touch layer 300 is provided on a side of the signal line layer 200 away from the base substrate 100, the touch layer 300 includes a plurality of touch traces 310, and the touch layer 300 includes a first touch layer 301 and a second touch layer 302 stacked, and a touch layer 301 and a touch layer 302 disposed on the first touch layer 301 and the second touch layer 302. 2, a touch trace 310 is at least partially located in the non-display area 120, the multiple touch traces 310 include a plurality of first touch traces 311 and a plurality of second touch traces 312 that are stacked, the first touch traces 311 are distributed in the first touch layer 301, and the second touch traces 312 are distributed in the second touch layer 302, and each touch trace 310 includes a first touch trace 311 and a second touch trace 312 connected in parallel; wherein the non-display area 120 includes a first non-display area, and the first non-display area is located outside the display area 110, and the orthographic projections of the multiple touch traces 310 in the first non-display area on the base substrate 100 at least partially overlap with the orthographic projections of the multiple signal lines 210 on the base substrate 100. In at least a portion of the touch lines 310 within the first non-display area, the first touch line 311 and the second touch line 312 belonging to the same touch line 310 respectively have a first center line O1 and a second center line O2, and in a direction perpendicular to the extension of the touch line 310, the first center line O1 and the second center line O2 are staggered.

[0099] In the display panel provided by the present disclosure, in at least a portion of the touch lines 310 within the first non-display area, the first touch line 311 and the second touch line 312 belonging to the same touch line 310 have a first center line O1 and a second center line O2, respectively. In a direction perpendicular to the extension of the touch line 310, the first center line and the second center line are staggered. In this way, the area used by the first touch line 311 and the second touch line 312 to block the signal line 210 is increased, which can reduce the reflection of light by the signal line 210 in this area, thereby preventing this area from reflecting and shining in strong light, which affects the display quality.

The second corner region 125 connects the second straight region 122 and the third straight region 123. There may be two second corner regions 125.

[0103] In some embodiments of the present disclosure, the base substrate 100 further includes an opening area 130, which is located within the display area 110. The opening area 130 can be used to set functional modules such as a camera, a distance sensor, a flash, or a speaker. The shape of the opening area 130 can be an elliptical, circular, square, or rounded rectangular shape. In this embodiment, the non-display area includes a second non-display area 126 located between the opening area 130 and the display area 110. The second non-display area 126 can be an annular area surrounding the opening area 130. The non-display area 120 includes the second non-display area 126. Of course, in some embodiments, the first non-display area can include the above-mentioned first straight area 121, the first corner area 124, the third straight edge area, the second corner area 125, and the second non-display area 126.

The signal line layer 200 includes a plurality of signal lines 210, which can be used to transmit various signals. The display panel also includes a plurality of sub-pixels. The signal lines 210 can connect the sub-pixels and the peripheral chip 400 to transmit various signals to the sub-pixels. For example, the signal lines 210 include scan signal lines 214 for transmitting scan signals, data signal lines 213 for transmitting data signals, and luminous signal lines for transmitting luminous signals, etc., although the present disclosure does not specifically limit this. The signal lines 210 can be located in the display area 110 and the non-display area 120, with different signal lines 210 having different distribution locations on the base substrate 100. In the present disclosure, the signal lines 210 are at least partially located in the non-display area 120. That is, the signal lines 210 can be divided into multiple segments, with some segments being located in the display area 110 and some segments being located in the non-display area 120. For example, some segments of the data signal line 213 are located in the display area 110, and some segments are located in the non-display area 120, such as the first straight area 121, the first corner area 124, or the second non-display area 126. For another example, some segments of the scan signal line 214 are located in the display area 110, and some segments are located in the second straight area 122, the first corner area 124, or the second non-display area 126. For another example, some segments of the light-emitting signal line are located in the display area 110, and some segments are located in the second non-display area 126. Further, in the present disclosure, the signal line 210 may be the data signal line 213.

[0105] In the present disclosure, the signal line layer 200 may include multiple metal layers, different signal lines 210 may be distributed in different metal layers, and different segments of the same signal line 210 may also be distributed in different metal layers, which is not specifically limited in the present disclosure. The material of the signal line 210 may be a metal material, such as molybdenum (Mu) or copper (Cu), etc., but is not limited thereto. In some embodiments of the present disclosure, the number of signal lines 210 located in the first corner area 124, the first straight area 121 and the second non-display area 126 is large and the arrangement is relatively dense. For example, the spacing between two adjacent signal lines 210 located in the first corner area 124 or the first straight area 121 does not exceed 1.5μm, such as 1μm, 0.5μm or 0.1μm, etc.

[0106] As shown in Figure 4, in some embodiments of the present disclosure, the display panel further includes a driving circuit layer and a light-emitting device layer, and the driving circuit layer may include the above-mentioned signal line layer 200. The driving circuit layer may be composed of a multi-layer film structure. The light-emitting device layer includes a plurality of light-emitting devices. The driving circuit layer may include a pixel circuit, and the pixel circuit is used to drive the light-emitting device of the OLED display panel to emit light. Each sub-pixel may include a pixel circuit and a light-emitting device. The pixel circuit may be a pixel circuit such as 7T1C, 7T2C, 6T1C or 6T2C, and its structure is not particularly limited here. Among them, nTmC means that a pixel circuit includes n transistors (represented by the letter "T") and m capacitors (represented by the letter "C"). The number of pixel circuits is multiple, and one pixel circuit corresponds to driving one light-emitting device to emit light. The data signal line 213 is connected to the source or drain of the transistor in the pixel circuit.

[0107] Taking the transistor in the driving circuit as a top-gate thin film transistor as an example, the driving circuit layer includes an active layer 216, a first gate insulation layer 217, a first gate metal layer 218, a second gate insulation layer 219, an interlayer dielectric layer 221, a first source and drain layer 222, a first planarization layer 223, a second source and drain layer 224 and a second planarization layer 225.

[0108] The active layer 216 is arranged on one side of the base substrate 100; the first gate insulating layer 217 is arranged on the side of the active layer 216 away from the base substrate 100, and the first gate insulating layer 217 covers the active layer 216; the first gate metal layer 218 is arranged on the side of the first gate insulating layer 217 away from the base substrate 100, and the first gate metal layer 218 may include the gate of the transistor and the first plate of the capacitor. A second gate insulating layer 219 is disposed on a side of the first gate metal layer 218 away from the substrate 100, and covers the first gate metal layer 218. A second gate metal layer 220 is disposed on a side of the second gate insulating layer 219 away from the substrate 100, and may include a second plate of a capacitor. An interlayer dielectric layer 221 is disposed on a side of the second gate insulating layer 219 away from the substrate 100. A first source / drain layer 222 is disposed on a side of the interlayer dielectric layer 221 away from the substrate 100, and includes the source and drain of the transistor, which are connected to the active layer 216. A first planarizing layer 223 is disposed on a side of the first source / drain layer 222 away from the substrate 100, a second source / drain layer 224 is disposed on a side of the first planarizing layer 223 away from the substrate 100, and a second planarizing layer 225 is disposed on a side of the second source / drain layer 224 away from the substrate 100. Furthermore, the driving circuit layer further includes a light shielding layer 215 disposed between the base substrate 100 and the active layer 216 .

[0109] The signal line layer 200 may include a first gate metal layer 218, a second gate metal layer 220, a first source / drain layer 222, and a second source / drain layer 224. The signal line 210 may be distributed in any of these conductive layers. It should be noted that the display panel driver circuit layer may also have other structures, such as a driver circuit layer including bottom-gate transistors, but this disclosure does not limit this.

[0110] The light emitting device layer is provided on a side of the driving circuit layer away from the base substrate 100. The light emitting device layer further includes a pixel definition layer 229, which separates a plurality of light emitting devices.

[0111] The pixel definition layer 229 is disposed on the side of the driver circuit layer away from the base substrate 100. The pixel definition layer 229 includes multiple pixel openings, each of which defines the area of ​​a light-emitting device. The shape of the pixel openings, i.e., the outline of their orthographic projection on the base substrate 100, can be a polygon, a smooth closed curve, or other shape, and is not specifically limited herein.

[0112] Taking an OLED light-emitting device as an example, the light-emitting device includes a first electrode layer 226, a light-emitting functional layer 227, and a second electrode layer 228, sequentially arranged in a direction away from the substrate 100. The first electrode layer 226 can serve as the anode layer of the light-emitting device. The light-emitting functional layer 227 covers the first electrode layer 226, and the second electrode layer 228 covers the light-emitting functional layer 227. The first electrode layer 226 can be connected to the source / drain of the transistor. The second electrode layer 228 covers the light-emitting functional layer 227 and can serve as the cathode layer of the light-emitting device. The second electrode layer 228 can be a single layer or a multilayer structure, and its material can include one or more conductive metals, metal oxides, and alloys. The light-emitting functional layer 227 is at least partially disposed within the pixel opening and can include a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer, and an electron injection layer, sequentially stacked in a direction away from the substrate 100. Visible light is generated by the recombination of holes and electrons into excitons in the light-emitting material layer, which then radiate photons. The specific light-emitting principle will not be detailed here.

[0113] In some embodiments, the signal line layer 200 may also include a first electrode layer 226 and a second electrode layer 228 , that is, the signal line 210 may be distributed in the first electrode layer 226 and the second electrode layer 228 .

[0114] The display panel also includes an encapsulation layer 230, which is provided on the side of the light-emitting device layer away from the base substrate 100. The encapsulation layer 230 can be used to protect the light-emitting device layer and prevent external water and oxygen from corroding the light-emitting device. In some embodiments of the present disclosure, encapsulation can be achieved by thin-film encapsulation (TFE). Specifically, the encapsulation layer 230 may include a first inorganic layer, an organic layer, and a second inorganic layer, wherein the first inorganic layer covers the surface of the light-emitting device layer away from the base substrate 100, the organic layer can be provided on the surface of the first inorganic layer away from the base substrate 100, and the boundary of the organic layer is limited to the inner side of the boundary of the first inorganic layer. The second inorganic layer covers the organic layer and the first inorganic layer not covered by the organic layer. The second inorganic layer can block the intrusion of water and oxygen, and the flexible organic layer can achieve flattening.

[0115] As shown in Figures 1, 2, 4, and 5, the touch layer 300 is disposed on the side of the signal line layer 200 away from the base substrate 100. Specifically, the touch layer 300 is disposed on the side of the encapsulation layer 230 away from the base substrate 100. The touch layer 300 includes multiple touch electrodes and multiple touch traces 310. The touch electrodes are located in the display area 110, and the touch traces 310 can be located in different areas of the base substrate 100. In some embodiments, the touch traces 310 are located outside the display area 110, that is, the touch traces 310 are located in the first straight area 121, the second straight area 122, or the first corner area 124. Such touch traces 310 can connect the touch electrodes to an integrated circuit or a flexible printed circuit board. In other embodiments, the touch traces 310 can be located in the second non-display area 126 to connect the touch electrodes on both sides of the second non-display area 126. The multiple touch traces 310 are arranged in different layers. That is, among the multiple touch lines 310, some touch lines 310 may be located on the same layer, and some touch lines 310 may be distributed on another layer. Of course, touch lines 310 transmitting the same signal may also be distributed on different layers, which is not specifically limited in this disclosure.

[0116] In some embodiments of the present disclosure, the multiple touch electrodes include multiple first electrode groups 330 extending along a first direction Y and multiple second electrode groups 331 extending along a second direction X. The multiple first electrode groups 330 may be arranged sequentially along the second direction X, and the multiple second electrode groups 331 may be arranged sequentially along the first direction Y. The first electrode groups 330 and the second electrode groups 331 are insulated from each other. The first direction Y and the second direction X are substantially perpendicular. The first electrode group 330 may be a driving electrode group connected to a driving circuit, and the second electrode group 331 may be a detection electrode group connected to a detection circuit. Alternatively, the first electrode group 330 may be a detection electrode group connected to a detection circuit, and the second electrode group 331 may be a driving electrode group connected to a driving circuit. Specifically, the first electrode group 330 and the second electrode group 331 may be connected to their respective driving circuits or detection circuits via touch traces 310 located outside the display area 110. When a user's finger touches the touchable area of ​​the display panel, the mutual capacitance between the insulated and intersecting first and second electrode groups 330, 331, at the touch point changes. The driving circuit scans the driving electrode groups in the first electrode group 330 and the second electrode group 331 one by one, and reads the signals of the detection electrode groups in each first electrode group 330 and the second electrode group 331 each time it scans a driving electrode group. After one round of scanning, the coordinates of the touch point can be determined, and the content corresponding to the touch operation is responded to based on the coordinates of the touch point.

[0117] In some embodiments, the plurality of touch traces 310 may include a plurality of first touch traces 311 and a plurality of second touch traces 312. The touch layer 300 includes a first touch layer 301 and a second touch layer 302, which are stacked. The second touch layer 302 is disposed on a side of the first touch layer 301 away from the base substrate 100. Furthermore, the touch layer 300 may further include a first insulating layer 303 disposed between the first touch layer 301 and the second touch layer 302. The first touch traces 311 may be distributed on the first touch layer 301, and the second touch traces 312 may be distributed on the second touch layer 302. Each touch trace 310 includes a first touch trace 311 and a second touch trace 312 connected in parallel. The orthographic projections of the plurality of touch traces 310 on the base substrate 100 in the first non-display area at least partially overlap with the orthographic projections of the plurality of signal lines 210 on the base substrate 100. In at least a portion of the touch lines 310 within the first non-display area, a first touch line 311 and a second touch line 312 belonging to the same touch line 310 respectively have a first center line O1 and a second center line O2. In a direction perpendicular to the extension of the touch line 310, the first center line O1 and the second center line O2 are staggered. In this way, while reducing the resistance of the touch line 310, the coverage area of ​​the touch line 310 on the signal line 210 is increased.

[0118] As shown in FIG. 25 and FIG. 26 , in the present disclosure, the first center line O1 refers to a line connecting the center points of the line width of the first touch trace 311 , and the second center line O2 refers to a line connecting the center points of the line width of the second touch trace 312 .

[0119] As shown in Figures 1, 2, and 5, Figure 2 is a schematic cross-sectional view of a portion of the non-display area 120 of the display panel in an embodiment. In the present disclosure, the light reflectivity of the touch layer 300 is lower than that of the signal line layer 200. The first centerline O1 and the second centerline O2 are staggered. Compared to a case where the first centerline O1 and the second centerline O2 are aligned, the arrangement of the present disclosure helps increase the coverage area of ​​the touch traces 310 over the signal lines 210. This reduces light reflection from the signal lines 210 in this area, preventing this area from appearing luminous under strong light and affecting display quality. In some embodiments of the present disclosure, the material of the touch layer 300 can be a conductive layer containing titanium (Ti) and aluminum (Al) formed using a low-temperature process. Furthermore, the orthographic projections of the plurality of signal lines 210 located at least partially in the non-display area 120 on the base substrate 100 are located within the orthographic projection of the at least one first touch trace 311 and the at least one second touch trace 312 combined on the base substrate 100.

[0120] The touch lines 310 can be located in different areas of the base substrate 100, and the touch lines 310 in different areas can be arranged differently. The touch layer 300 can also include a second insulating layer 304 and a protective layer 305. The second insulating layer 304 is disposed between the signal line layer 200 and the first touch layer 301, and the protective layer 305 is disposed on the side of the second touch layer 302 away from the base substrate 100.

[0121] Next, the covering of the signal line 210 by the touch lines 310 will be described in detail with reference to the touch lines 310 at different positions.

[0122] As shown in Figures 1, 2, and 5, in some embodiments of the present disclosure, touch traces 310 are located on the periphery of the display area 110, such as in the first straight area 121, the second straight area 122, and the first corner area 124. It should be noted that the plurality of signal lines 210 at least partially located in the non-display area 120 refers to at least a portion of all the plurality of signal lines 210 located in the non-display area 120, such as the signal lines 210 located in the first straight area 121 or the signal lines 210 located in the first corner area 124. For example, a first touch trace 311 and a second touch trace 312 belonging to the same touch trace 310 located in the first straight area 121 or the first corner area 124, respectively, have a first centerline O1 and a second centerline O2. In a direction perpendicular to the extension of the touch trace 310, the first centerline O1 and the second centerline O2 are staggered, as shown in Figures 5 to 15.

[0123] Figure 6 shows the layout of signal lines 210 in area A of Figure 5 , i.e., the layout of signal lines 210 in the first straight section 121. In this figure, signal lines 210 are distributed across different metal layers. Different fill patterns in the figure represent different metal layers, while the same fill pattern represents the same metal layer. Figure 7 shows the layout of first touch lines 311 and second touch lines 312 in area A of Figure 5 , i.e., the layout of first touch lines 311 and second touch lines 312 in the first straight section 121. Figure 8 shows a stacked diagram of signal lines 210, first touch lines 311, and second touch lines 312 in area A of Figure 5 , i.e., a diagram of the layers of signal lines 210, first touch lines 311, and second touch lines 312 in the first straight section 121.

[0124] Figure 9 shows the layout of signal lines 210 in area B of Figure 5 , i.e., the layout of signal lines 210 at the junction of the first straight region 121 and the first corner region 124. In this figure, signal lines 210 are distributed across different metal layers. Different fill patterns in the figure represent different metal layers, while the same fill pattern represents the same metal layer. Figure 10 shows the layout of first touch lines 311 and second touch lines 312 in area B of Figure 5 , i.e., the layout of first touch lines 311 and second touch lines 312 at the junction of the first straight region 121 and the first corner region 124. Figure 11 shows a layer stack of signal lines 210, first touch lines 311, and second touch lines 312 in area B of Figure 5 , i.e., a layer stack of signal lines 210, first touch lines 311, and second touch lines 312 at the junction of the first straight region 121 and the first corner region 124.

[0125] Figure 12 shows the layout of signal lines 210 in area C of Figure 5 , i.e., the layout of signal lines 210 in the first corner region 124. In this figure, signal lines 210 are distributed across different metal layers. Different fill patterns in the figure represent different metal layers, while the same fill pattern represents the same metal layer. Figure 13 shows the layout of first touch lines 311 and second touch lines 312 in area C of Figure 5 , i.e., the layout of first touch lines 311 and second touch lines 312 in the first corner region 124. Figure 14 shows a stacked diagram of signal lines 210, first touch lines 311, and second touch lines 312 in area C of Figure 5 , i.e., a diagram of the layers of signal lines 210, first touch lines 311, and second touch lines 312 in the first corner region 124.

[0126] Figure 15 shows the layout of the first touch trace 311 and the second touch trace 312 in area D of Figure 5 , specifically, the layout of the first touch trace 311 and the second touch trace 312 at the junction of the first corner region 124 and the second straight region 122. The dashed line in Figure 15 represents the boundary between the first corner region 124 and the second straight region 122. Since the present disclosure does not specifically limit the layout of the signal lines 210, the layout of the signal lines 210 in area D of Figure 5 is not shown. For details, reference can be made to the layout of the signal lines 210 in other areas, such as area A.

[0127] As can be seen from Figures 5 to 15, the first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 located in the first straight area 121 or the first corner area 124 have a first center line O1 and a second center line O2, respectively. In the direction perpendicular to the extension of the touch trace 310, the first center line O1 and the second center line O2 are staggered, and the first touch trace 311 and the second touch trace 312 together cover most of the signal line 210 located in this area.

[0128] The first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 in the second straight region 122 correspond to the first center line O1 and the second center line O2. In a direction perpendicular to the extension of the touch trace 310, the first center line O1 and the second center line O2 can be staggered or not staggered. That is, the first touch trace 311 and the second touch trace 312 in the second straight region 122 can combine to cover a larger area, or they can cover less of the signal line 210 in that area than in the first straight region 121 and the first corner region 124.

[0129] In actual applications, the number of signal lines 210 in the second straight region 122 is typically smaller than the number of signal lines 210 in the first straight region 121 and the first corner region 124. Therefore, even if the signal lines 210 in the second straight region 122 are not extensively covered, this region is unlikely to shine under strong light. As shown in Figures 5 and 16, Figure 16 shows the layout of the first touch traces 311 and second touch traces 312 in region E in Figure 5. In this figure, the first touch traces 311 and second touch traces 312 substantially overlap, with gaps between adjacent touch traces 310. In Figure 16, the second touch traces 312 are truncated for ease of illustration. Of course, preferably, the first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 in the second straight region 122 have a first center line O1 and a second center line O2, respectively. In a direction perpendicular to the extension of the touch trace 310, the first center line O1 and the second center line O2 are staggered. In this embodiment, the arrangement of the first touch trace 211 and the second touch trace 212 can refer to the arrangement of the first straight region 121.

[0130] Furthermore, other areas outside the display area 110 may also be similar. For example, the first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 located in the third straight area 123 or the second corner area 125 have a first centerline O1 and a second centerline O2, respectively. In a direction perpendicular to the extension of the touch trace 310, the first centerline O1 and the second centerline O2 are staggered. The arrangement of the first touch trace 211 and the second touch trace 212 in the third straight area 123 can refer to the arrangement of the first straight area 121, and the arrangement of the first touch trace 121 and the second touch trace 122 in the second corner area 125 can refer to the arrangement of the first corner area 124. For example, as shown in Figure 18, Figure 18 is a schematic diagram of the arrangement of the first touch trace 311 and the second touch trace 312 in area G of Figure 5, which is similar to the arrangement of the first corner area 124.

[0131] As shown in Figures 7, 10, and 13, the orthographic projections of the first touch traces 311 and the second touch traces 312 on the substrate 100 located in the first straight region 121 or the first corner region 124 are arranged alternately. That is, in the first straight region 121 and the first corner region 124, the arrangement of the first touch traces 311 and the second touch traces 312 is: first touch trace 311, second touch trace 312, first touch trace 311, second touch trace 312, and so on. The spacing between two adjacent first touch traces 311 is no less than 3 μm, and the spacing between two adjacent second touch traces 312 is no less than 3 μm to prevent interference between transmitted signals. Of course, the orthographic projections of the first touch traces 311 and the second touch traces 312 on the substrate 100 located in the third straight region 123 or the second corner region 125 can also be arranged alternately.

[0132] As shown in Figures 2, 5, 7, and 27, in this type of embodiment, the orthographic projections of the first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 on the substrate 100 at least partially overlap, and the first touch trace 311 and the second touch trace 312 whose orthographic projections on the substrate 100 overlap are electrically connected one-to-one through the via holes in the first insulating layer 303 to transmit the same signal. For example, the first touch trace 311 and the second touch trace 312 are connected to form a first signal line, which can be connected to the first electrode group 330 for transmitting a drive signal. For another example, the first touch trace 311 and the second touch trace 312 are connected to form a second signal line, which can be connected to the second electrode group 331 for transmitting a detection signal. Of course, the first signal line can also be connected to the second electrode group 331 for transmitting a detection signal, and the second signal line can also be connected to the first electrode group 330 for transmitting a drive signal, but this disclosure does not limit this.

[0133] In this type of embodiment, the first touch trace 311 and the second touch trace 312 are interconnected to transmit the same signal, which helps reduce resistance and load. Furthermore, to improve the stability of the connection between the first touch trace 311 and the second touch trace 312, the overlapping area of ​​the orthographic projection of the first touch trace 311 and the orthographic projection of the second touch trace 312 on the substrate 100, belonging to the same touch trace 310, has a width of no less than 1.5 μm in the line width direction, so that the first touch trace 311 and the second touch trace 312 are connected by vias.

[0134] As shown in Figures 1 and 5 to 16, in some embodiments, the first touch trace 311 and the second touch trace 312 both include a first straight segment 313, a first connecting segment 314, a first curved segment 315, a second connecting segment 316, and a second straight segment 317 connected in sequence. The first straight segment 313 is located in the first straight area 121, the first connecting segment 314, the first curved segment 315, and the second connecting segment 316 are all located in the first corner area 124, and the second straight segment 317 is located in the second straight area 122. As shown in Figure 15, along the direction from the second straight area 122 to the first corner area 124, the overlapping area of ​​the orthographic projection of the second connecting segment 316 of the first touch trace 311 on the substrate 100 and the orthographic projection of the corresponding second connecting segment 316 of the second touch trace 312 on the substrate 100 gradually decreases. That is, along the direction from the second straight region 122 to the first corner region 124, the second connecting segment 316 of the first touch trace 311 and the second connecting segment 316 of the second touch trace 312 are gradually offset. For a stacking diagram of the first straight segment 313 of the first touch trace 311 and the second touch trace 312, refer to FIG7 ; for a stacking diagram of the first connecting segment 314 of the first touch trace 311 and the second touch trace 312, refer to FIG10 ; for a stacking diagram of the first curved segment 315 of the first touch trace 311 and the second touch trace 312, refer to FIG13 ; and for a stacking diagram of the second straight segment 317 of the first touch trace 311 and the second touch trace 312, refer to FIG16 .

[0135] In the present disclosure, the first touch trace 311 and the corresponding second touch trace 312 refer to the first touch trace 311 and the second touch trace 312 that transmit the same signal.

[0136] Furthermore, the difference in line width between the first touch trace 311 and the second touch trace 312 does not exceed 0.1 μm. The widths of the first touch trace 311 and the second touch trace 312 are substantially equal. The ratio of the overlapping area of ​​the orthographic projection of the second straight segment 317 of the first touch trace 311 and the orthographic projection of the second straight segment 317 of the second touch trace 312 on the substrate 100 to the area of ​​the second straight segment 317 of the first touch trace 311 or the area of ​​the second straight segment 317 of the second touch trace 312 is not less than 95%. In other words, the second straight segment 317 of the first touch trace 311 and the second straight segment 317 of the second touch trace 312 substantially overlap.

[0137] In some embodiments, the line width of the first touch trace 311 and the second touch trace 312 is no less than 4.2 μm. As shown in FIG16 , the second straight segment 317 of the first touch trace 311 and the second straight segment 317 of the second touch trace 312 substantially completely overlap, and the overlap width is equal to the width of the touch trace 310. As shown in FIG15 , the overlap width of the second connecting segment 316 of the first touch trace 311 and the second connecting segment 316 of the second touch trace 312 gradually decreases from the second straight region 122 to the first corner region 124, and the minimum overlap width is no less than 1.5 μm. The overlapping width of the first straight segment 313, the first connecting segment 314, the first curved segment 315 of the first touch trace 311 and the first straight segment 313, the first connecting segment 314, and the first curved segment 315 of the second touch trace 312 is not less than 1.5 μm, and the first straight segment 313, the first connecting segment 314, the first curved segment 315 of the first touch trace 311 and the first straight segment 313, the first connecting segment 314, and the first curved segment 315 of the second touch trace 312 do not completely overlap.

[0138] It should be noted that this design solution is also applicable to the first touch trace 311 and the second touch trace 312 located in the second corner region 125. As shown in Figures 5 and 17 to 20, for example, the first touch trace 311 and the second touch trace 312 each further include a third connecting segment 318, a second curved segment 319, a fourth connecting segment 320, and a third straight segment 321. The third connecting segment 318, the second curved segment 319, and the fourth connecting segment 320 are located in the second corner region 125, and the third straight segment 321 is located in the third straight region 123. As shown in Figure 17, along the direction from the second straight region 122 to the second corner region 125, the overlapping area of ​​the orthographic projection of the third connecting segment 318 of the first touch trace 311 on the substrate 100 and the orthographic projection of the corresponding third connecting segment 318 of the second touch trace 312 on the substrate 100 gradually decreases. That is, the overlapping width between the third connecting segment 318 of the first touch trace 311 and the third connecting segment 318 of the second touch trace 312 gradually decreases from the second straight region 122 to the second corner region 125 , and the minimum overlapping width is not less than 1.5 μm.

[0139] The third straight segment 321 of the first touch trace 311 and the third straight segment 321 of the second touch trace 312 may substantially completely overlap or partially overlap, with the overlap width being no less than 1.5 μm. When the third straight segment 321 of the first touch trace 311 and the third straight segment 321 of the second touch trace 312 substantially completely overlap, such as when the ratio of the overlapping area to the area of ​​the third straight segment 321 of the first touch trace 311 or the area of ​​the third straight segment 321 of the second touch trace 312 is no less than 95% (as shown in FIG. 20 ), then, as shown in FIG. 19 , the overlapping area of ​​the orthographic projection of the fourth connecting segment 320 of the first touch trace 311 on the substrate 100 and the orthographic projection of the corresponding fourth connecting segment 320 of the second touch trace 312 on the substrate 100 gradually decreases along the direction from the third straight region 123 to the second corner region 125.

[0140] As shown in Figures 2 and 5, in some other embodiments of the present disclosure, the touch traces 310 are located in the second non-display area 126. In such embodiments, the opening area 130 divides the at least one first electrode group 330 or the at least one second electrode group 331 into two sub-electrode groups located on either side of the opening area 130; the touch traces 310 connect the two sub-electrode groups of the first electrode group 330 or the touch traces 310 connect the two sub-electrode groups of the second electrode group 331; and the orthographic projections of the plurality of signal lines 210 located in the second non-display area 126 on the base substrate 100 at least partially overlap with the orthographic projections of the plurality of touch traces 310 on the base substrate 100.

[0141] In this type of embodiment, the first electrode group 330 includes a plurality of first electrodes 332, with adjacent first electrodes 332 located in the display area 110 connected by a first bridge line 334. The second electrode group 331 includes a plurality of second electrodes 333, with adjacent second electrodes 333 located in the display area 110 connected by a second bridge line 335. Specifically, the first electrodes 332, the first bridge line 334, the second electrodes 333, and the second bridge line 335 may be distributed on different touch layers 300. For example, in one embodiment, the second bridge line 335 is distributed on the first touch layer 301, while the first electrodes 332, the first bridge line 334, and the second electrodes 333 are distributed on the second touch layer 302. In another embodiment, the first electrodes 332, the first bridge line 334, and the second electrodes 333 are distributed on the first touch layer 301, while the second bridge line is distributed on the second touch layer 302.

[0142] In the opening area 130 , the separated first electrode group 330 and second electrode group 331 may be connected by the first touch trace 311 and / or the second touch trace 312 .

[0143] As shown in Figures 2 and 21, in one embodiment, the opening area 130 divides a first electrode group 330 and a second electrode group 331 into two sub-electrode groups located on either side of the opening area 130. The two sub-electrode groups of the first electrode group 330 are connected via the first touch trace 311 or the second touch trace 312. Correspondingly, the two sub-electrode groups of the second electrode group 331 are connected via the second touch trace 312 or the first touch trace 311. The orthographic projections of the plurality of signal lines 210 located in the second non-display area 126 on the substrate 100 are substantially within the orthographic projections of the first touch trace 311 and the second touch trace 312 combined on the substrate 100. In this embodiment, the size of the opening area 130 is generally smaller than the size of a first electrode 332 or a second electrode 333. Therefore, the opening area 130 separates the first electrode group 330 from the second electrode group 331. In this embodiment, the first touch trace 311 and the second touch trace 312 are relatively wide, so as to cover a large area of ​​the signal line 210 in the second non-display area 126. For example, the first touch trace 311 is a single, wide conductive ring structure, or the second touch trace 312 is a single, wide conductive ring structure, so as to cover the signal line 210 in the second non-display area 126.

[0144] As shown in Figures 2, 22, and 23, Figure 23 is a schematic diagram illustrating the arrangement of the first touch traces 311 and the second touch traces 312 in area I of Figure 22. In another embodiment, the opening area 130 divides the multiple first electrode groups 330 and the multiple second electrode groups 331 into two sub-electrode groups located on either side of the opening area 130. That is, in this embodiment, the opening area 130 is larger than the first electrodes 332 and the second electrodes 333, thereby isolating the multiple first electrode groups 330 from the multiple second electrode groups 331. The orthographic projections of the first touch trace 311 and the second touch trace 312 on the base substrate 100 at least partially overlap, and the first touch trace 311 and the second touch trace 312 whose orthographic projections on the base substrate 100 overlap are connected one-to-one; as shown in FIG24 , the partially correspondingly connected first touch trace 311 and the second touch trace 312 are combined to form a first connection line 336, and the partially correspondingly connected first touch trace 311 and the second touch trace 312 are combined to form a second connection line 337; the first connection line 336 connects the two sub-electrode groups of the first electrode group 330, the second connection line 337 connects the two sub-electrode groups of the second electrode group 331, and the first connection line 336 and the second connection line 337 are insulated. Specifically, the area where the first connecting line 336 and the second connecting line 337 intersect is a single-layer design. For example, at the position where the first connecting line 336 and the second connecting line 337 intersect, the area of ​​the first connecting line 336 only includes the second touch line 312, and the corresponding area of ​​the second connecting line 337 only includes the first touch line 311. In this way, the insulation setting of the first connecting line 336 and the second connecting line 337 can be realized.

[0145] In this type of embodiment, as shown in FIG23 , within at least a portion of the touch traces 310 within the second non-display area 126 , a first touch trace 311 and a second touch trace 312 belonging to the same touch trace 310 have a first centerline O1 and a second centerline O2, respectively. The first centerline O1 and the second centerline O2 are staggered in a direction perpendicular to the extension of the touch trace 310. Furthermore, the orthographic projections of the first touch trace 311 and the orthographic projections of the second touch trace 312 on the substrate 100 within at least a portion of the touch traces 310 within the second non-display area 126 are arranged alternately. That is, within the second non-display area 126 , the first touch trace 311 and the second touch trace 312 are arranged in the following pattern: first touch trace 311, second touch trace 312, first touch trace 311, second touch trace 312, and so on. The spacing between two adjacent first touch traces 311 is no less than 3 μm, and the spacing between two adjacent second touch traces 312 is no less than 3 μm to prevent interference between transmitted signals. Furthermore, the width of the overlapping area between the orthographic projections of the first touch traces 311 and the orthographic projections of the second touch traces 312 on the base substrate 100 is no less than 1.5 μm in the line width direction, allowing the first touch traces 311 and the second touch traces 312 to be connected by vias.

[0146] As shown in Figures 1, 2, 5, and 28, in some embodiments of the present disclosure, a display panel provided by the present disclosure includes a base substrate 100, a signal line layer 200, and a touch layer 300. The base substrate 100 includes a display area 110 and a non-display area 120. The signal line layer 200 is disposed on one side of the base substrate 100 and includes a plurality of signal lines 210, at least partially located in the non-display area 120. The touch layer 300 is disposed on a side of the signal line layer 200 away from the base substrate 100 and includes a plurality of touch traces 310, at least partially located in the non-display area 120. The non-display area 120 includes a first non-display area, which is located outside the display area 110. The orthographic projections of the plurality of touch traces 310 in the first non-display area on the base substrate 100 at least partially overlap with the orthographic projections of the plurality of signal lines 210 on the base substrate 100. In the first non-display area, there is a first gap L1 between the orthographic projections of two adjacent touch lines 310 on the base substrate 100, and there is a second gap L2 between the orthographic projections of two adjacent touch lines 310 in the non-display area 120 other than the first non-display area on the base substrate 100, and the first gap L1 is smaller than the second gap L2.

[0147] In this type of embodiment, the structural arrangement of the display area 110, the non-display area 120, and the first non-display area can refer to the above embodiment and will not be described in detail here. For example, the first non-display area may include a first straight area 121, a first corner area 124, a third straight area 123, and a second corner area 125.

[0148] In some embodiments, the first gap L1 is 0.1 to 0.3 times the second gap L2.

[0149] In the first non-display area, the minimum distance between the orthographic projections of the first side and the fourth side of two adjacent touch traces 310 on the base substrate 100 is a first gap L1; in the non-display area 120 other than the first non-display area, the minimum distance between the orthographic projections of the first side and the fourth side of two adjacent touch traces 310 on the base substrate 100 is a second gap L2.

[0150] As shown in FIG28 , in the first straight region 121 , there is a first gap L1 between the orthographic projections of two adjacent touch lines 310 on the base substrate 100 , and there is a second gap L2 between the orthographic projections of two adjacent touch lines 310 on the base substrate 100 in the second straight region 122 , and the first gap L1 is smaller than the second gap L2.

[0151] The touch layer 300 includes a first touch layer 301 and a second touch layer 302 that are stacked, and a first insulating layer 303 disposed between the first touch layer 301 and the second touch layer 302. Each of the multiple touch traces 310 includes a first touch trace 311 and a second touch trace 312 that are connected in parallel. The first touch trace 311 is distributed in the first touch layer 301, and the second touch trace 312 is distributed in the second touch layer 302. In at least some of the touch traces 310, the orthographic projections of the first touch trace 311 and the second touch trace 312 belonging to the same touch trace 310 on the base substrate 100 at least partially overlap.

[0152] In the first non-display area, the unit overlapping area between the first touch trace 311 and the second touch trace 312 is smaller than the unit overlapping area between the first touch trace 311 and the second touch trace 312 in the non-display area 120 other than the first non-display area.

[0153] In the present disclosure, the unit overlapping area refers to the overlapping area of ​​the first touch trace 311 per unit area and the second touch trace 312 per unit area.

[0154] In one embodiment, the first touch trace 311 includes a first side and a second side that are oppositely disposed, and the second touch trace 312 includes a third side and a fourth side that are oppositely disposed. In the first non-display area, the orthographic projection of the third side on the substrate 100 is located between the orthographic projections of the first side and the second side on the substrate 100, and the orthographic projection of the second side on the substrate 100 is located between the orthographic projections of the third side and the fourth side on the substrate 100.

[0155] As shown in FIG1 , FIG2 , FIG5 , FIG7 , FIG25 and FIG26 , the present disclosure further provides a method for manufacturing a display panel, comprising:

[0156] Step S100 , providing a base substrate 100 , wherein the base substrate 100 includes a display area 110 and a non-display area 120 ;

[0157] Step S200 , forming a signal line layer 200 on one side of the base substrate 100 , wherein the signal line layer 200 includes a plurality of signal lines 210 , and the signal lines 210 are at least partially located in the non-display area 120 ;

[0158] Step S300, forming a touch layer 300 on a side of the signal line layer 200 away from the base substrate 100, the touch layer 300 including a plurality of touch traces 310, and the touch layer 300 including a first touch layer 301 and a second touch layer 302 arranged in a stacked manner, and a first insulating layer 303 provided on the first touch layer 301 and the second touch layer 302, the touch traces 310 being at least partially located in the non-display area 120, the plurality of touch traces 310 including a plurality of first touch traces 311 and a plurality of second touch traces 312 arranged in a stacked manner, the first touch traces 311 being distributed in the first touch layer 301, and the second touch traces 312 being distributed in the second touch layer 302, and each touch trace 310 including the first touch trace 311 and the second touch trace 312 being connected in parallel;

[0159] The non-display area 120 includes a first non-display area, which is located outside the display area 110. The orthographic projections of the plurality of touch traces 310 in the first non-display area on the base substrate 100 at least partially overlap with the orthographic projections of the plurality of signal lines 210 on the base substrate 100. Within at least a portion of the touch traces 310 in the first non-display area, a first touch trace 311 and a second touch trace 312 belonging to the same touch trace 310 have a first centerline O1 and a second centerline O2, respectively. The first centerline O1 and the second centerline O2 are staggered in a direction perpendicular to the extension of the touch trace 310.

[0160] In step S100, the non-display area 120 may include multiple regions. In some embodiments of the present disclosure, the non-display area 120 is located outside the display area 110 and includes a first non-display area. The first non-display area is located outside the display area 110. The non-display area 120 also includes a second straight area 122 located on at least one side of the display area 110 in the second direction X. The first non-display area includes a first straight area 121 and a first corner area 124. The first straight area 121 is located on one side of the display area 110 in the first direction Y; the first corner area 124 connects the first straight area 121 and the second straight area 122. The non-display area 120 also includes a binding area 17 located on the side of the first straight area 121 away from the display area 110. Furthermore, the first non-display area also includes a third straight area 123 and a second corner area 125 . The third straight area 123 is located on a side of the display area 110 away from the first straight area 121 . The second corner area 125 connects the second straight area 122 and the third straight area 123 .

[0161] In some embodiments of the present disclosure, the base substrate 100 further includes an opening area 130, which is located within the display area 110. The display panel further includes a second non-display area 126 located between the opening area 130 and the display area 110. The non-display area 120 further includes the second non-display area 126.

[0162] In step S200, the signal line layer 200 is formed with a relatively dense arrangement of signal lines 210. The material of the signal lines 210 includes a metal material with strong light reflectivity, such as molybdenum (Mu). The formed signal line layer 200 can be multi-layered, such as forming a first metal layer and a second metal layer stacked together, with the signal lines 210 in the first metal layer and the signal lines 210 in the second metal layer being relatively densely arranged.

[0163] In step S300, the formed touch layer 300 may include two layers: a first touch layer 301 and a second touch layer 302. The light reflectivity of the first touch layer 301 and the second touch layer 302 is lower than that of the signal line layer 200. Specifically, the light reflectivity of the touch layer 300 can be adjusted by adjusting the material and formation process of the touch layer 300.

[0164] In one embodiment, the materials of the first touch layer 301 and the second touch layer 302 may include titanium (Ti) and aluminum (Al). The first touch layer 301 and the second touch layer 302 may both have a multi-layer stacked structure. For example, the structure of the first touch layer 301 and the second touch layer 302 is titanium (Ti)-aluminum (Al)-titanium (Ti), that is, a stack of a titanium (Ti) metal layer, an aluminum (Al) metal layer, and a titanium (Ti) metal layer. Furthermore, the formation temperature of the first touch layer 301 and the second touch layer 302 is no higher than 85°C. In this way, a touch layer 300 with low light reflectivity can be formed. Specifically, a titanium metal layer can be first formed by evaporation on the side of the signal line layer 200 away from the base substrate, and then an aluminum metal layer can be formed by evaporation on the side of the titanium metal layer away from the base substrate. Subsequently, a titanium metal layer can be formed again on the side of the aluminum metal layer away from the base substrate. The temperature of the entire process does not exceed 85°C.

[0165] The plurality of touch traces 310 may include a plurality of first touch traces 311 and a plurality of second touch traces 312. The first touch traces 311 may be distributed in the first touch layer 301, and the second touch traces 312 may be distributed in the second touch layer 302. The touch traces 310 may be located in different regions of the base substrate 100, and the touch traces 310 in different regions may be arranged differently. Specifically, the touch traces 310 may be formed with a pattern specific to each region by performing different patterning in different regions. For example, a first touch material layer may be formed on a side of the signal line layer 200 away from the base substrate 100, and then this touch material layer may be patterned to form the first touch layer 301 including the first touch traces 311. Then, a second touch material layer may be formed on a side of the first touch layer 30 away from the base substrate 100, and then this touch material layer may be patterned to form the second touch layer 302 including the second touch traces 312. The patterns of the first touch traces 301 and second touch traces 302 formed in different regions can vary. The specific pattern can vary depending on the arrangement of the signal lines 210 in that region. For example, as shown in Figures 5, 7, 10, and 13, the patterns of the first touch traces 301 and second touch traces 302 are formed such that the orthographic projections of the plurality of signal lines 210 located in the first straight region 121 or the first corner region 124 on the substrate 100 are within the orthographic projections of the plurality of first touch traces 311 and the plurality of second touch traces 312 combined on the substrate 100. Furthermore, the orthographic projections of the first touch traces 301 and the second touch traces 302 formed by at least some of the touch traces 310 on the substrate 100 are arranged alternately. That is, in the first straight area 121 and the first corner area 124 , the first touch traces 311 and the second touch traces 312 are arranged in the following order: first touch trace 311 , second touch trace 312 , first touch trace 311 , second touch trace 312 . . . , and so on.

[0166] The present disclosure provides a method for manufacturing a display panel, in which the light reflectivity of the touch layer 300 of the display panel formed is lower than that of the signal line layer 200. At least a portion of the multiple touch lines 310 located in the non-display area 120 can cover the multiple signal lines 210 located in the area. In this way, the reflection of light by the signal lines 210 in the area can be reduced, thereby preventing the area from reflecting light and shining under strong light, thereby affecting the display quality.

[0167] Furthermore, when forming the touch layer 300, the touch layer 300 is a stacked conductive layer including a titanium metal layer, an aluminum metal layer and a titanium metal layer, and the formation process does not exceed 85°C. Under this condition, a touch layer 300 with lower light reflectivity can be formed, thereby helping to better reduce the light reflectivity of the signal line layer 210.

[0168] The present disclosure further provides a display device including a display panel. The display panel may be any of the display panels described above. The specific structure and beneficial effects thereof may be referenced above with respect to the display panel embodiments, and are not further described herein. The display device of the present disclosure may be an electronic device such as a mobile phone, a tablet computer, or a television, and these are not listed here.

[0169] It should be noted that although the steps of the method of the present disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in this specific order, or that all steps must be performed to achieve the desired results. Additional or alternative steps, such as omitting certain steps, combining multiple steps into one step, and / or decomposing a step into multiple steps, should all be considered part of this disclosure.

The present disclosure is capable of other embodiments and can be implemented and executed in a variety of ways. The aforementioned variations and modifications fall within the scope of the present disclosure.
