Description

Technical Field

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

[0002] Touchscreens, as an input medium, are currently the simplest, most convenient, and most natural form of human-computer interaction. With the development of display technology, more and more display panels are integrating touch functionality.

[0003] Touchscreen technology is a technology that detects the position (in coordinates) touched by a finger, stylus, or other object when it is mounted on the front of a display device. This information is then sent to the CPU to determine the input information. Currently, touchscreens have a wide range of applications, including touchscreen smartphones, laptops, and other mobile terminals, as well as human-machine interfaces in industrial automation.

[0004] To enable touch functionality in a display device, touch electrodes are typically introduced within the device. When these electrodes are made of metal mesh, parts of the mesh are often visible from a wide viewing angle, affecting the display quality. Summary of the Invention

[0005] In view of this, the present invention provides a display panel and display device that, by avoiding the opening of the second color pixel by the break portion, reduces or avoids the problem of the metal mesh near the break portion being visible at a wide viewing angle, thereby improving the overall display effect of the display panel.

[0006] In a first aspect, the present invention provides a display panel, characterized in that it includes a display layer and a touch layer disposed on one side of the display layer;

[0007] The display layer includes multiple sub-pixels and multiple pixel openings. The sub-pixels include a first color sub-pixel and a second color sub-pixel. The pixel openings include a first color pixel opening and a second color pixel opening. The first color sub-pixel corresponds to the first color pixel opening, and the second color sub-pixel corresponds to the second color pixel opening. The area of ​​the first color pixel opening is larger than the area of ​​the second color pixel opening.

[0008] The touch layer includes a plurality of touch electrodes that are insulated from each other. Each touch electrode includes a plurality of electrically connected metal meshes. The orthographic projection of the metal meshes onto the plane of the display panel is located outside the orthographic projection of the pixel openings onto the plane of the display panel.

[0009] At least some of the adjacent touch electrodes are provided with a break;

[0010] The second color pixel opening includes a plurality of first pixel openings arranged along a first direction, and each first pixel opening includes a first edge and a second edge opposite to each other along a second direction, wherein the first direction and the second direction intersect.

[0011] The first edge and the second edge are straight edges, and the area between the straight line containing the first edge and the straight line containing the second edge is a first area, and the break portion avoids the first area;

[0012] Alternatively, the first edge and the second edge are arc-shaped edges, the first tangent of the first edge and the second tangent of the second edge are both parallel to the first direction, the area between the first tangent and the second tangent is the first area, and the break portion avoids the first area.

[0013] Secondly, based on the same inventive concept, the present invention also provides a display device, including the display panel provided in the first aspect of the present invention.

[0014] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0015] In the display panel and display device provided by this invention, a touch layer is disposed on one side of the display layer. The touch layer includes a plurality of mutually insulated touch electrodes. The display layer includes a plurality of pixel openings. The orthographic projection of the metal mesh in the touch electrodes onto the plane of the display panel is located outside the orthographic projection of the pixel openings onto the plane of the display panel. Adjacent touch electrodes are insulated from each other by a disconnection. The pixel openings include a first color pixel opening and a second color pixel opening. The area of ​​a second color pixel opening is smaller than the area of ​​the first color pixel opening. The human eye is more sensitive to the second color light. If the disconnection is disposed around the second color pixel opening, the light emitted by the second color sub-pixel is more likely to leak at the disconnection, resulting in the metal mesh being visible. When a disconnection is disposed between adjacent touch electrodes, the embodiments of this invention avoid the second color pixel opening as much as possible, reducing the amount of light emitted by the second color sub-pixel that is emitted through the disconnection. This helps to reduce or avoid the problem of the metal mesh being visible at large viewing angles, thus improving the display effect.

[0016] Of course, any product implementing this invention need not necessarily achieve all of the technical effects described above at the same time.

[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0037] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] Various modifications and variations can be made to this invention without departing from its spirit or scope, as will be apparent to those skilled in the art. Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this invention can be combined with each other without contradiction.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] Figure 1 This diagram illustrates the relative positional relationship between pixel apertures and the metal mesh of touch electrodes in related technologies. The touch electrodes include a metal mesh, and adjacent touch electrodes are separated by a break K' in the metal mesh. The break K' is located around the pixel aperture of the green sub-pixel G, which has a smaller aperture area. Since the green sub-pixel has a smaller aperture area, the human eye can more clearly perceive the green color. During display, the light emitted by the green sub-pixel can pass through the break around it, resulting in the metal mesh being visible at a wide viewing angle, thus affecting the display effect.

[0041] Therefore, the present invention provides a display panel and display device, which aims to improve the problem of light leakage from the broken parts of the metal mesh, which makes the metal mesh visible at a wide viewing angle.

Figure 4 The diagram shows one possible arrangement of touch electrodes in the touch layer. Figure 5 The diagram shown illustrates the relative positional relationship between the pixel opening corresponding to the sub-pixel and the metal mesh of the touch electrode in an embodiment of the present invention. Figure 6 The diagram shown illustrates the relative positional relationship between the pixel opening corresponding to the sub-pixel and the metal mesh of the touch electrode in an embodiment of the present invention. Figure 7 The diagram shown illustrates another relative positional relationship between the pixel opening corresponding to the sub-pixel and the metal mesh of the touch electrode in an embodiment of the present invention.

[0043] Please refer to Figures 2 to 5 This invention provides a display panel 100, including a display layer 10 and a touch layer 20 disposed on one side of the display layer 10.

[0044] The display layer 10 includes multiple sub-pixels and multiple pixel openings. The sub-pixels include a first color sub-pixel 11 and a second color sub-pixel 12. The pixel openings include a first color pixel opening P1 and a second color pixel opening P2. The first color sub-pixel 11 corresponds to the first color pixel opening P1, and the second color sub-pixel 12 corresponds to the second color pixel opening P2. The area of ​​the first color pixel opening P1 is larger than the area of ​​the second color pixel opening P2.

[0045] The touch layer 20 includes a plurality of mutually insulated touch electrodes 21. Each touch electrode 21 includes a plurality of electrically connected metal meshes 22. The orthographic projection of the metal meshes 22 onto the plane of the display panel is located outside the orthographic projection of the pixel opening onto the plane of the display panel. At least some adjacent touch electrodes 21 are provided with a break portion K. Optionally, the metal meshes 22 are mesh-like structures formed by the intersection of multiple metal lines.

[0046] The second color pixel opening P2 includes a plurality of first pixel openings P21 arranged along the first direction D1. The first pixel opening P21 includes a first edge B1 and a second edge B2 opposite to each other along the second direction D2. The first direction D1 and the second direction D2 intersect, and optionally, the first direction D1 and the second direction D2 are perpendicular.

[0047] The first edge B1 and the second edge B2 are straight edges. The area between the straight line where the first edge B1 is located and the straight line where the second edge B2 is located is the first region Q1. The break part K avoids the first region Q1.

[0048] Alternatively, the first edge B1 and the second edge B2 are arc-shaped edges. The first tangent X1 of the first edge B1 and the second tangent X2 of the second edge B2 are both parallel to the first direction. The area between the first tangent X1 and the second tangent X2 is the first region Q1. The disconnection part K avoids the first region Q1. That is to say, the disconnection part K is not set in the first region Q1, but in other regions outside the first region Q1.

[0049] Optionally, the display panel provided in this embodiment can be a display panel using organic light-emitting diode (OLED) display technology. The basic structure of the light-emitting functional layer of an OLED display panel includes an anode 301, a light-emitting material layer 302, and a cathode 303. When a suitable voltage is supplied, holes in the anode 301 and electrons in the cathode 303 combine in the light-emitting material layer, generating light. Compared to thin-film transistor liquid crystal displays, OLED display devices have high visibility and high brightness, and are more energy-efficient, lightweight, and thinner. Of course, in some other embodiments of the present invention, the display panel can also be a display panel using inorganic light-emitting diode (OLED) display technology, such as a MicroLED display panel, or a MiniLED display panel, etc.

[0050] Figure 3 The description focuses on an OLED display panel. Optionally, an encapsulation layer 50 is provided on the side of the cathode 303 away from the anode 301. The display panel also includes a substrate 00 and a driving layer 40 disposed between the substrate and the display layer 10. The driving layer 40 contains a driving circuit for providing a driving voltage to the display layer 10 to drive it to emit light. Optionally, the driving layer 40 includes a first metal layer m1, a capacitor metal layer mc, and a second metal layer m2 disposed on the substrate 00. The first metal layer m1 may be, for example, a gate metal layer, and the gate of the transistor in the display panel may be disposed on the first metal layer m1. The capacitor metal layer mc is used to form a capacitor structure with the first metal layer m1 or the second metal layer m2. The source electrode s and drain electrode d of the transistor T in the display panel may be located in the second metal layer m2. The semiconductor layer poly includes a source region and a drain region, which are formed by doping with N-type or P-type impurity ions. The source electrode s of the transistor is electrically connected to the source region of the semiconductor layer poly through a contact hole, and the drain electrode d of the transistor is electrically connected to the drain region of the semiconductor layer poly through a contact hole. Optionally, the encapsulation layer 50 is a thin-film encapsulation layer, including a first inorganic layer 51, an organic layer 52, and a second inorganic layer 53, to isolate water and oxygen and prevent external moisture and oxygen from affecting the light-emitting material layer.

[0051] Optionally, the display layer 10 includes a pixel definition layer 19, which includes a plurality of pixel openings extending through it along its thickness direction. A light-emitting material layer 302 fills at least the pixel openings. Optionally, the pixel opening corresponding to the first color sub-pixel 11 is filled with a first-color light-emitting material, and the pixel opening corresponding to the second color sub-pixel 12 is filled with a second-color light-emitting material. Along the thickness direction of the pixel definition layer 19, the anode 301 and the cathode 303 are located on opposite sides of the light-emitting material layer. The area of ​​the pixel opening mentioned in this embodiment refers to the overlapping area of ​​the anode 301 and the opening of the pixel definition layer 19 along a direction perpendicular to the substrate 00. When the opening of the pixel definition layer 19 is manifested as follows... Figure 3 In the inverted trapezoidal structure shown, the area of ​​the pixel opening refers to the area of ​​the bottom adjacent to the anode in the inverted trapezoidal structure. Optionally, the second color sub-pixel 12 is a green sub-pixel, and the area of ​​the pixel opening corresponding to this second color sub-pixel 12 is relatively small, as the human eye is more sensitive to green. Optionally, the first color sub-pixel 11 is either a red sub-pixel or a blue sub-pixel. Figure 5 The embodiment shown uses a rectangle as an example to illustrate the shape of the pixel opening's orthographic projection onto the plane of the display panel. Figure 7 The illustrated embodiment uses the shape of the orthographic projection of the pixel opening onto the plane of the display panel as a circle, ellipse, or other non-rectangular irregular structure as an example for illustration. However, the actual shape of the pixel opening is not limited. In some other embodiments of the present invention, the shape of the orthographic projection of the pixel opening onto the plane of the display panel may also be other.

[0052] Figure 5 and Figure 7 The embodiments shown only illustrate two possible pixel arrangement structures in the display panel, but do not limit the actual pixel arrangement structure in the display panel.

[0053] by Figure 5 and Figure 7 Taking the illustrated embodiment as an example, the second color pixel opening P2 includes a plurality of first pixel openings P21 arranged along the first direction D1, and the emission color of the sub-pixels corresponding to the plurality of first pixel openings P21 is the second color. The first pixel opening P21 includes a first edge B1 and a second edge B2 disposed opposite to each other along the second direction D2, and the first edge B1 and the second edge B2 can be... Figure 5 The straight edge shown can also be Figure 7 The curved edge shown.

[0054] Figure 4The description only uses a mutual capacitance touch electrode 21 as an example. In some other embodiments of the present invention, the touch electrode 21 may also be a self-capacitance structure, which is not specifically limited by the present invention. Taking the mutual capacitance touch electrode 21 as an example, the touch electrode 21 includes a plurality of first touch electrodes 211 arranged and insulated along the row direction, and a plurality of second touch electrodes 212 arranged and insulated along the column direction. The first touch electrodes 211 and the second touch electrodes 212 are insulated from each other. Optionally, both the first touch electrodes 211 and the second touch electrodes 212 include a plurality of electrode blocks. Although not shown in the figure, each electrode block includes, for example, a plurality of electrode blocks. Figure 5 or Figure 7 The metal mesh shown can optionally have multiple pixel openings corresponding to the orthographic projection of the same electrode block onto the plane of the display panel. Insulation is required between adjacent first touch electrodes 211 along the column direction, between adjacent second touch electrodes 212 along the row direction, and between adjacent electrode blocks of the first touch electrodes 211 and the second touch electrodes 212. In actual manufacturing, this is achieved by breaking the metal mesh at the corresponding locations. In related technologies, the location of the break can easily make the metal mesh visible. Therefore, this invention improves the location of the break in the metal mesh.

[0055] by Figure 5 Taking the illustrated embodiment as an example, the first pixel opening P21 is a rectangular structure, and the first edge B1 and the second edge B2 are both straight edges. The area between the straight line containing the first edge B1 and the straight line containing the second edge B2 is the first region Q1. Assuming that both the first edge B1 and the second edge B2 extend along the first direction D1, the break is set to avoid the first region Q1. That is, the break is set in a region other than the first region Q1. Along the first direction D1, the break does not overlap with the second color pixel opening P2. Even if the human eye is more sensitive to the light of the second color, the light emitted by the second color sub-pixel will not be emitted from the break or the amount of light emitted from the break will be less. Therefore, the problem of the metal mesh being visible at a large viewing angle due to light leakage from the second color sub-pixel at the break is avoided or reduced, thus improving the overall display effect of the display panel.

[0056] Figure 5 In the illustrated embodiment, the first pixel opening P21 includes an edge extending along a first direction D1 and an edge extending along a second direction D2, wherein the first direction D1 and the second direction D2 intersect. Figure 5 The illustrated embodiment is only used as an example where the first edge B1 and the second edge B2 extend along the first direction D1. The same principle applies when the first edge B1 and the second edge B2 extend along the second direction D2. For example, please refer to... Figure 6In this embodiment, the first edge B1 and the second edge B2 extend along the second direction D2. The area defined by the straight line containing the first edge B1 and the second edge B2 is the first region Q1. When the break part K is set to avoid the first region Q1, the break part K does not overlap with the second color pixel opening P2 along the second direction D2. This also helps to reduce or avoid the situation where light emitted from the second color pixel opening P2 exits through the break part, thus improving the overall display effect of the display panel. Assuming that the scan lines in the display panel extend along the row direction and the data lines extend along the column direction, optionally... Figure 5 and Figure 6 In the embodiment shown, the second direction D2 is the extension direction of the scan line in the display panel, and the first direction D1 is the extension direction of the data line in the display panel.

[0057] by Figure 7 Taking the illustrated embodiment as an example, the first pixel opening P21 is an arc-shaped structure, and both the first edge B1 and the second edge B2 are arc-shaped edges. The first edge B1 has a first tangent X1, and the second edge B1 has a second tangent X2 parallel to the first tangent X1. The area between the first tangent X1 and the second tangent X2 is the first region Q1. When the break part K is set to avoid the first region Q1, it is equivalent to setting the break part K in a region other than the first region Q1. Even if the human eye is more sensitive to the light of the second color, the light emitted by the second color sub-pixel will not be emitted from the break part, or the amount of light emitted by the second color sub-pixel from the break part will be reduced. Therefore, the problem of the metal mesh being visible at a large viewing angle due to light leakage at the break part position of the second color sub-pixel is avoided or weakened, thus improving the overall display effect of the display panel. Optionally, assuming that the scan lines in the display panel extend along the row direction and the data lines extend along the column direction, then Figure 7 In the embodiment shown, the first direction D1 is a direction that intersects with the extension directions of both the scan line and the data line, and the second direction D2 is a direction that intersects with the extension directions of both the scan line and the data line.

[0058] Figure 8 The diagram shown illustrates another relative positional relationship between the pixel opening corresponding to the sub-pixel and the metal mesh of the touch electrode 21 in an embodiment of the present invention. Please refer to [the diagram]. Figure 2 and Figure 8In an optional embodiment of the present invention, the sub-pixel further includes a third color sub-pixel 13, and the pixel opening further includes a third color pixel opening P3, with the third color sub-pixel 13 corresponding to the third color pixel opening P3; the area of ​​the third color pixel opening P3 is smaller than the area of ​​the first color pixel opening P1, and greater than or equal to the area of ​​the second color pixel opening P2; along the extension direction of the first region Q1 (in this embodiment, the extension direction of the first region Q1 is taken as the first direction D1 for explanation), the break portion K does not overlap with the third color pixel opening P3, thus effectively setting the break portion as far away from the third color pixel opening P3 as possible. Figure 8 Taking the illustrated embodiment as an example, along the first direction D1, the break portion K does not overlap with either the first color pixel opening P1 or the third color pixel opening P3. Optionally, when the second color sub-pixel 12 is a green sub-pixel, the first color sub-pixel 11 and the third color sub-pixel 13 are respectively a red sub-pixel and a blue sub-pixel. Assuming that the scan lines in the display panel extend along the row direction and the data lines extend along the column direction, optionally, Figure 8 In the embodiment shown, the first direction D1 is the extension direction of the data line in the display panel, and the second direction D2 is the extension direction of the scan line in the display panel.

[0059] When the sub-pixel also includes a third color sub-pixel 13, and the area of ​​the pixel opening corresponding to the third color sub-pixel 13 is smaller than the area of ​​the pixel opening corresponding to the first color sub-pixel 11, and greater than or equal to the area of ​​the pixel opening corresponding to the second color sub-pixel 12, the human eye is more sensitive to the light emitted by the third color sub-pixel 13 and less sensitive to the light emitted by the first color sub-pixel. When the break is set as far away from the third color pixel opening P3 as possible, the light emitted by the third color pixel opening P3 will not be emitted from the break, or the amount of light emitted by the third color pixel opening P3 emitted from the break will be less. Therefore, it is beneficial to reduce the phenomenon of visible metal mesh caused by light leakage of the third color emitted light.

[0060] It should be noted that, although Figure 8 In the illustrated embodiment, some of the disconnected portions are located at the upper left and upper right corners of the third color pixel opening P3, and some of the disconnected portions are located at the lower left and lower right corners of the first color pixel opening P1. In the direction parallel to the plane of the display panel, the locations of the disconnected portions are relatively far from the center of the pixel opening, and the light emitted from the pixel opening that is directed towards the disconnected portions is also relatively weak. Therefore, there is less light leakage at the disconnected portions, and the phenomenon of visible metal mesh at a wide viewing angle is also weaker, or almost non-existent.

[0061] Figure 9 The diagram shown is a schematic representation of a broken portion of the metal mesh of the touch electrode 21. Please refer to... Figure 4 and Figure 9 In an optional embodiment of the present invention, among adjacent touch electrodes, one touch electrode includes a first line segment XD1, and the other touch electrode includes a second line segment XD2. The surface of the first line segment XD1 facing the second line segment XD2 is a first end face M1, and the surface of the second line segment XD2 facing the first line segment XD1 is a second end face M2. The break portion K is located between the first end face M1 and the second end face M2. The first end face M1 can be regarded as the surface of the first line segment XD1 opposite to the second line segment XD2, and the second end face M2 can be regarded as the surface of the second line segment XD2 opposite to the first line segment XD1. In the embodiment, only the top view of the first line segment XD1 and the second line segment XD2 on the plane where the display panel is located is shown. The orthographic projection of the first end face M1 and the second end face M2 on the plane where the display panel is located is represented as a line segment.

[0062] When adjacent touch electrodes 21 are insulated from each other by a break, assuming one touch electrode includes a first line segment XD1 and the other touch electrode includes a second line segment XD2, the break is located between the first line segment XD1 and the second line segment XD2. In actual manufacturing, the first line segment XD1 and the second line segment XD2 are originally a complete line segment connected together. Later, a break K is formed on this complete line segment, dividing the complete line segment into the first line segment XD1 and the second line segment XD2, which are insulated from each other. The end face of the first line segment XD1 facing the second line segment XD2 is the first end face M1, and the end face of the second line segment XD2 facing the first line segment XD1 is the second end face M2. The break K can be regarded as the area between the first end face M1 and the second end face M2.

[0063] Continue to refer to Figure 9 In an optional embodiment of the present invention, the orthographic projection of the first end face M1 onto the plane where the display panel is located is a first straight line segment L1, and the orthographic projection of the second end face M2 onto the plane where the display panel is located is a second straight line segment L2. The first straight line segment L1 and the second straight line segment L2 are parallel and perpendicular to the extension direction of the first line segment XD1, respectively.

[0064] In this embodiment, after the break is formed, the orthographic projection of the first end face M1 corresponding to the first line segment XD1 onto the plane of the display panel forms a first straight line segment L1, and the orthographic projection of the second end face M2 corresponding to the second line segment XD2 onto the plane of the display panel forms a second straight line segment L2. The first straight line segment L1 and the second straight line segment L2 are parallel and both are perpendicular to the extension direction of the first line segment XD1, making the break K a regular shape. The process of forming the regular-shaped break K is relatively simple, which helps to simplify the manufacturing process of the touch electrode 21 in the display panel, and thus helps to improve the production efficiency of the display panel.

[0065] Continue to refer to Figure 9In an optional embodiment of the present invention, along the extension direction of the first line segment XD1, the minimum distance between the break portion K and the edge of the orthographic projection of the second color pixel opening P2 on the plane where the display panel is located is S1, where S1≥5.9μm.

[0066] When the shape of the break K is regular, this embodiment further limits the minimum distance S1 between the break K and the opening P2 of the second color pixel. The minimum distance S1 refers to the distance along the extension direction of the first line segment XD1, between the one closer to the opening P2 in the first straight line segment L1 and the other in the orthographic projection of the opening P2 onto the plane of the display panel, and the distance towards the edge of the break K. The smaller the minimum distance, for example, when S1 < 5.9 μm, the greater the amount of light leaking from the break in the light emitted by the second color sub-pixel. When the display panel is viewed at a wide viewing angle, the visible metal mesh around the break will be more pronounced. When the minimum distance is set to S1 ≥ 5.9 μm, the distance between the opening P2 of the second color pixel and the break along the extension direction of the first line segment XD1 is increased. The amount of light emanating from the second color sub-pixel and directed towards the break will decrease accordingly, thereby helping to weaken the visible metal mesh around the break and improving the display effect of the display panel.

[0067] Since the human eye is more sensitive to the second color, when a break is set around the opening P2 of the second color pixel, the minimum distance S1 between the opening of the second color sub-pixel and the break should be guaranteed to be ≥ 5.9μm. This will weaken the problem of the metal mesh being visible when the second color light is emitted from the break due to the sensitivity of the second color.

[0068] Of course, in some other embodiments of the present invention, if the break portion is disposed around the opening of the third color pixel, the minimum distance between the opening of the third color pixel and the break portion can also meet the above-mentioned distance requirement, which is equivalent to... Figure 9 Based on the embodiment shown, the opening of the second color pixel can be replaced with the opening of the third color pixel to weaken the problem of light leakage at the break point caused by the third color sub-pixel, which makes the metal mesh visible.

[0069] Figure 10 The diagram shows a structural schematic of the broken part of the metal mesh of the touch electrode 21. This embodiment shows another implementation scheme of the first straight line segment L1 and the second straight line segment L2 corresponding to the first line segment XD1 and the second line segment XD2.

[0070] Please refer to Figure 10In an optional embodiment of the present invention, the orthographic projection of the first end face M1 onto the plane where the display panel is located is a first straight line segment L1, and the orthographic projection of the second end face M2 onto the plane where the display panel is located is a second straight line segment L2. The first straight line segment L1 and the second straight line segment L2 are parallel, and the first straight line segment L1 intersects the extension direction of the first line segment XD1 but is not perpendicular to it.

[0071] In this embodiment, the first straight line segment L1 corresponding to the first end face M1 of the first line segment XD1 and the second straight line segment L2 corresponding to the second end face M2 of the second line segment XD2 are still parallel structures. The first straight line segment L1 is inclined relative to the extension direction of the first line segment XD1, and the second straight line segment L2 is also inclined relative to the extension direction of the first line segment XD1. That is, the first straight line segment L1 intersects the extension direction of the first line segment XD1 but is not perpendicular to it. At this time, the break portion has an inclined elongated structure. In this embodiment, along the direction from the first line segment XD1 to the opening P2 of the second color pixel, the break portion K does not overlap with the opening of the second color sub-pixel. This is equivalent to avoiding the area with a large light emission from the second color sub-pixel and placing the break portion in the area with a small light emission from the second color sub-pixel to reduce the problem of metal visibility at a large viewing angle when light exits from the break portion.

[0072] Continue to refer to Figure 10 In an optional embodiment of the present invention, the orthographic projections of the first line segment XD1 and the second line segment XD2 onto the plane of the display panel are adjacent to the orthographic projection of the second color pixel opening P2 onto the plane of the display panel; along the extension direction of the first line segment XD1, the first straight line segment L1 is located between the second straight line segment L2 and the second color pixel opening P2; the first straight line segment L1 includes a first end DB1 and a second end DB2 disposed opposite to each other, and along the extension direction of the first line segment XD1, the first end DB1 is located between the second end DB2 and the second color pixel opening P2; along the arrangement direction of the first line segment XD1 and the second color pixel opening P2, the second end DB2 is located between the first end DB1 and the second color pixel opening P2.

[0073] Please refer to Figure 10Along the extension direction of the first line segment XD1, the first straight line segment L1 is located between the second straight line segment L2 and the second color pixel opening P2. That is, the first straight line segment L1 is closer to the second color pixel opening P2 than the second straight line segment L2. The first straight line segment L1 includes a first end DB1 and a second end DB2. Along the direction from the first line segment XD1 towards the second color pixel opening P2, the second end DB2 is located between the first end DB1 and the second color pixel opening P2. The first straight line segment L1 can be considered as being formed by rotating clockwise from a position parallel to the X-axis with the first end DB1 as the origin, where the angle is greater than 0° and less than 90°. When the first straight line segment L1 rotates clockwise from a direction parallel to the X-axis, as the rotation angle increases, the second end DB2 of the first straight line segment L1 becomes farther from the second color pixel opening P2. The amount of light emitted from the second color sub-pixel hitting the break gradually decreases, and the visible metallic mesh at the corresponding position of the break becomes weaker, thus improving the visibility of the metallic mesh at large viewing angles.

[0074] When the first straight line segment L1 is rotated clockwise as described above, along the extension direction of the first straight line segment XD1, assuming the distance between the first end DB1 of the first straight line segment L1 and the lower edge of the second color pixel opening P2 is D02, and the distance between the second end DB2 of the first straight line segment L1 and the lower edge of the second color pixel opening P2 is D01, then D01 > D02. That is, the second end DB2 of the first straight line segment L1 is farther away from the second color pixel opening P2 relative to the first end DB1. Assuming the second straight line segment L2 also includes a third end DB3 and a fourth end DB4, along the direction from the first straight line segment L1 to the second color pixel opening P2, the fourth end DB4 of the second straight line segment L2 is located between its third end DB3 and the second color pixel opening P2. Since the first straight line segment L1 is parallel to the second straight line segment L2, the fourth end DB4 of the second straight line segment L2 is farther away from the second color pixel opening P2 relative to its third end DB3. The area between the first end DB1 of the first straight segment L1 and the third end DB3 of the second straight segment L2 can be regarded as the first opening of the disconnection. The area between the second end DB2 of the first straight segment L1 and the fourth end DB4 of the second straight segment L2 can be regarded as the second opening of the disconnection. Along the extension direction of the first line segment XD1, the second opening is farther away from the second color pixel opening P2 than the first opening. When the light emitted by the second color sub-pixel passes through the disconnection, it will first pass through the second opening. Since the second opening is farther away from the second color pixel opening P2, less light will be emitted through the second opening, thereby effectively reducing the problem of the metal mesh being visible at a large viewing angle due to light leakage from the disconnection.

[0075] It should be noted that, Figure 10This embodiment illustrates one possible structure for the break when it is positioned outside the opening of the second color pixel. The shape of the break can also be used when it is positioned outside the opening of the third color pixel or outside the first color pixel. Figure 10 The shape of the illustrated embodiment is not specifically limited by the present invention.

[0076] Figure 11 The diagram shows a structural schematic of the broken portion of the metal mesh of the touch electrode 21. This embodiment shows an example where the broken portion has an irregular shape.

[0077] Please refer to Figure 11 In an optional embodiment of the present invention, the first end face M1 includes a first sub-surface BM1 and a second sub-surface BM2 connected together; the second end face M2 includes a third sub-surface BM3 and a fourth sub-surface BM4 connected together; wherein the first sub-surface BM1 and the third sub-surface BM3 are opposite to each other, and the second sub-surface BM2 and the fourth sub-surface BM4 are opposite to each other.

[0078] Specifically, in this embodiment, the first end face M1 and the second end face M2 of the first line segment XD1 are not planar structures. The first end face M1 includes a connected first sub-surface BM1 and a second sub-surface BM2. The orthographic projection of the first sub-surface BM1 and the second sub-surface BM2 onto the plane where the display panel is located is a sharp angle. The second end face M2 includes a connected third sub-surface BM3 and a fourth sub-surface BM4. The orthographic projection of the third sub-surface BM3 and the fourth sub-surface BM4 onto the plane where the display panel is located is also a sharp angle. The first sub-surface BM1 and the third sub-surface BM3 form a light-emitting channel, and the second sub-surface BM2 and the fourth sub-surface BM4 form another light-emitting channel. When the light emitted by the second color sub-pixel passes through the break, it needs to pass through the two light-emitting channels. Compared with the way the light-emitting channel extends perpendicularly to the first line segment XD1, this embodiment uses two light-emitting channels to increase the light transmission path. The light will attenuate during transmission, so when the light emitted by the sub-pixel passes through the two light-emitting channels in this embodiment, the amount of light emitted will be less. Therefore, it is also beneficial to reduce the problem of visible metal mesh caused by light leakage at the break.

[0079] Continue to refer to Figure 11 In one optional embodiment of the present invention, the plane containing the first sub-surface BM1 intersects the plane containing the second sub-surface BM2, the plane containing the third sub-surface BM3 intersects the plane containing the fourth sub-surface BM4, the first sub-surface BM1 is parallel to the third sub-surface BM3, and / or the second sub-surface BM2 is parallel to the fourth sub-surface BM4.

[0080] Figure 11The illustrated embodiment shows a scheme where the first sub-surface BM1 is parallel to the third sub-surface BM3, and the second sub-surface BM2 is parallel to the fourth sub-surface BM4. This arrangement of parallel sub-surfaces simplifies the formation process of the break portion K. In some other embodiments of the invention, the first sub-surface BM1 and the third sub-surface BM3 can be parallel, and the extension directions of the second sub-surface BM2 and the fourth sub-surface BM4 can intersect; or, the extension directions of the first sub-surface BM1 and the third sub-surface BM3 can intersect, and the second sub-surface BM2 and the fourth sub-surface BM4 can be parallel. All of these arrangements help to extend the transmission path of light emitted from the sub-pixels in the break portion, reduce the amount of light emitted through the break portion, and improve the visibility of the metal mesh.

[0081] Figure 12 The diagram shows a structural schematic of the broken portion of the metal mesh of the touch electrode 21. This embodiment shows a scheme in which the first end of the first line segment XD1 and the second end of the second line segment XD2 both include three sub-surfaces.

[0082] Please refer to Figure 12 In an optional embodiment of the present invention, the first end face M1 further includes a fifth sub-surface BM5 connected to the second sub-surface BM2, and the second end face M2 further includes a sixth sub-surface BM6 connected to the fourth sub-surface BM4, with the fifth sub-surface BM5 and the sixth sub-surface BM6 opposite to each other.

[0083] Specifically, in this embodiment, the orthographic projections of the first sub-surface BM1, the second sub-surface BM2, and the fifth sub-surface BM5 corresponding to the first end face M1 onto the plane of the display panel are three straight line segments, which are connected in pairs to form a Z-shape. Similarly, the orthographic projections of the third sub-surface BM3, the fourth sub-surface BM4, and the sixth sub-surface BM6 corresponding to the second end face M2 onto the plane of the display panel are also three straight line segments, which are also connected in pairs to form a Z-shape. The first sub-surface BM1 and the third sub-surface BM3 form one channel, the second sub-surface BM2 and the fourth sub-surface BM4 form another channel, and the fifth sub-surface BM5 and the sixth sub-surface BM6 form yet another channel. When the light from the sub-pixel exits through the break, it needs to pass through these three channels, further extending the light transmission path and reducing the amount of light emitted from the break, thus helping to weaken or eliminate the problem of visible metal mesh.

[0084] Optionally, the first sub-surface BM1 and the third sub-surface BM3 are parallel, the second sub-surface BM2 and the fourth sub-surface BM4 are parallel, and the fifth sub-surface BM5 and the sixth sub-surface BM6 are parallel, in order to simplify the manufacturing process of the disconnected part.

[0085] Optionally, the first sub-surface BM1 and the fifth sub-surface BM5 are perpendicular to the second sub-surface BM2, respectively, and the third sub-surface BM3 and the sixth sub-surface BM6 are perpendicular to the fourth sub-surface BM4, respectively.

[0086] It should be noted that this embodiment is only used as an example where the extension direction of the straight line segment formed by the orthographic projection of the six sub-surfaces onto the display panel is parallel or perpendicular to the extension direction of the first line segment XD1. In some other embodiments of the present invention, the straight line segment formed by the orthographic projection of at least some of the sub-surfaces onto the display panel may also be inclined relative to the extension direction of the first line segment XD1, for example, intersecting the extension direction of the first line segment XD1 but not perpendicular to it. The present invention does not specifically limit this.

[0087] Continue to refer to Figure 12 In an optional embodiment of the present invention, the length L2 of the line segment corresponding to the orthographic projection of the second sub-surface BM2 onto the plane where the display panel is located is greater than the length L1 of the line segment corresponding to the orthographic projection of the first sub-surface BM1 onto the plane where the display panel is located, and / or is greater than the length L5 of the line segment corresponding to the orthographic projection of the fifth sub-surface BM5 onto the plane where the display panel is located; the length L4 of the line segment corresponding to the orthographic projection of the fourth sub-surface BM4 onto the plane where the display panel is located is greater than the length L3 of the line segment corresponding to the orthographic projection of the third sub-surface BM3 onto the plane where the display panel is located, and / or is greater than the length L6 of the line segment corresponding to the orthographic projection of the sixth sub-surface BM6 onto the plane where the display panel is located.

[0088] In this embodiment, it is assumed that the channel formed by the relative arrangement of the first sub-surface BM1 and the third sub-surface BM3 is the first channel, the channel formed by the relative arrangement of the second sub-surface BM2 and the fourth sub-surface BM4 is the second channel, and the channel formed by the relative arrangement of the fifth sub-surface BM5 and the sixth sub-surface BM6 is the third channel. The second channel is connected to both the first and third channels, and the extension direction of the second channel intersects with the extension directions of the first and third channels. When the light emitted from the sub-pixel is directed toward the break, it passes through the third channel, the second channel, and the first channel in sequence before exiting. Since the lengths of the first and second channels are limited by the linewidths of the first line segment XD1 and the second line segment XD2, they cannot be made too large. When the extension direction of the second channel is the same as the extension direction of the first line segment XD1, the length of the second channel is not limited by the linewidth of the first line segment XD1, and therefore the length of the second channel can be set to be larger, for example, greater than the lengths of the first and second channels. Thus, by increasing the length of the second channel, the light transmission path at the break can be increased. The longer the light transmission path, the greater the light loss and the less light emitted from the break, which is more conducive to improving the problem of light leakage at a large viewing angle caused by light leakage at the break.

[0089] It should be noted that, Figure 12 This explanation only uses the example of the interlocking structure at the periphery of the opening P2 of the second color pixel. The same structure can be used when the opening is placed in other locations. Figure 12 The present invention does not specifically limit the structure shown.

[0090] The above embodiments use a scheme where the orthographic projections of the first end face M1 of the first line segment XD1 and the second end face M2 of the second line segment XD2 onto the plane of the display panel are a single straight line segment or a broken line segment formed by at least two straight line segments. In some other embodiments of the present invention, the orthographic projections of the first end face M1 of the first line segment XD1 and the second end face M2 of the second line segment XD2 onto the plane of the display panel can also be represented as arc-shaped line segments, for example, please refer to Figure 13 .

[0091] Figure 13 The diagram shows another structural schematic of the broken portion of the metal mesh of the touch electrode 21. In an optional embodiment of the present invention, the first end face M1 includes a first arc-shaped surface, and the projection of the first arc-shaped surface onto the plane where the display panel is located is a first arc-shaped segment; the second end face M2 includes a second arc-shaped surface, and the projection of the second arc-shaped surface onto the plane where the display panel is located is a second arc-shaped segment; the first arc-shaped surface includes a first protrusion, and the second arc-shaped surface includes a second recess, the shapes of the first protrusion and the second recess are fitted together, that is, the shapes of the first arc-shaped segment and the second arc-shaped segment are fitted together.

[0092] When the orthographic projections of the first end face M1 and the second end face M2 onto the display panel are both arc-shaped line segments, the shapes of the first and second arc-shaped line segments fit together, thus... Figure 13 Taking the illustrated embodiment as an example, "fitting" refers to the first and second arc-shaped segments bending in the same direction. For instance, both the first and second arc-shaped segments bend along the direction from the second segment XD2 to the first segment XD1. The first and second arc-shaped segments form a curved light guide channel. Compared to a light guide channel whose extension direction is perpendicular to a single segment, the curved light guide channel helps to increase the transmission distance of light in the break and reduce the amount of light emitted from the break. It also helps to mitigate the problem of the visible metal mesh.

[0093] Continue to refer to Figure 5 In an optional embodiment of the present invention, the display panel includes a first pixel column 71 and a second pixel column 72 arranged alternately along a second direction D2. The first pixel column 71 includes a plurality of second color sub-pixels 12 and third color sub-pixels 13 arranged alternately along a first direction D1. The second pixel column 72 includes a plurality of first color sub-pixels 11 arranged along a first direction D1, wherein the first direction D1 is the column direction and the second direction D2 is the row direction.

[0094] Specifically, Figure 5 The illustrated embodiment shows a pixel arrangement structure for a display panel provided by an embodiment of the present invention. In this pixel arrangement structure, the second color sub-pixels 12 and the third color sub-pixels 13 in the first pixel column 71 are arranged alternately along the first direction D1, and the first color sub-pixels 11 in the second pixel column 72 are arranged along the first direction D1. The area of ​​the pixel opening corresponding to the first color sub-pixel 11 is larger than the area of ​​the pixel opening corresponding to the second color sub-pixel 12 and also larger than the area of ​​the pixel opening corresponding to the third color sub-pixel 13. The pixel arrangement structure in this embodiment is simple, and the orthographic projection of each pixel opening onto the display panel is a square structure, making the manufacturing process relatively simple.

[0095] In an optional embodiment of the present invention, the metal mesh 22 includes a first metal line segment 221 and a second metal line segment 222, wherein the first metal line segment 221 extends along a first direction D1, and the second metal line segment 222 extends along a second direction D2. When the pixel arrangement adopts such... Figure 5 In the structure shown, the extension direction of the metal lines in the metal mesh can follow the extension direction of the edge of the pixel opening of the sub-pixel, that is, follow the arrangement direction of the pixel column and the arrangement direction of the sub-pixels in the pixel column. This helps to simplify the manufacturing process of the metal mesh and improve the production efficiency of the display panel.

[0096] Figure 14 The diagram shown illustrates another relative positional relationship between the pixel opening corresponding to the sub-pixel and the metal mesh of the touch electrode 21 in an embodiment of the present invention.

[0097] Please refer to Figure 14In an optional embodiment of the present invention, the display panel includes a plurality of pixel column units 80 arranged along a third direction D3. Each pixel column unit 80 includes a first pixel column 81, a second pixel column 82, and a third pixel column 83 arranged sequentially along the third direction D3. The first pixel column 81 includes a plurality of first color sub-pixels 11 arranged along a fourth direction D4; the second pixel column 82 includes a plurality of second color sub-pixels 12 arranged along the fourth direction D4; and the third pixel column 83 includes a plurality of third color sub-pixels 13 arranged along the fourth direction D4. The third direction D3 intersects with the first direction D1, the second direction D2, and the fourth direction D4, and the fourth direction D4 intersects with the first direction D1 and the second direction D2. In the same pixel column unit 80, the first color sub-pixels 11 and the third color sub-pixels 13 are located in the same row along the third direction D3, while the second color sub-pixels 12 are located in another row. Optionally, when the second color sub-pixel 12 is a green sub-pixel, the first color sub-pixels 11 and the third color sub-pixels 13 are respectively a red sub-pixel and a blue sub-pixel. Optionally, in this embodiment, the third direction D3 is the row direction, and the fourth direction D4 is the column direction. Assuming the scan lines in the display panel extend along the row direction and the data lines extend along the column direction, then... Figure 14 In the embodiment shown, the third direction D3 is the extension direction of the scan line in the display panel, the fourth direction D4 is the extension direction of the data line in the display panel, the first direction D1 is the direction that intersects with the extension directions of both the scan line and the data line in the display panel, and the second direction D2 is the direction that intersects with the extension directions of both the scan line and the data line in the display panel.

[0098] Specifically, this embodiment illustrates another feasible pixel arrangement structure of the present invention. In the pixel column unit 80 included in the display panel, the first pixel column 81, the second pixel column 82, and the third pixel column 83 each include only sub-pixels of a single color, and the colors of the sub-pixels corresponding to different pixel columns are different. Along the fourth direction D4, the sub-pixels in the second pixel column 82 are staggered with the sub-pixels in the first pixel column 81 and with the sub-pixels in the third pixel column 83. For example, along the fourth direction D4, the second-color sub-pixel 12 is located between two adjacent first-color sub-pixels 11 and simultaneously between two adjacent third-color sub-pixels 13. This type of pixel arrangement structure is also applicable to the position setting of the break portion in the embodiments of the present invention. Figure 14Taking the first pixel opening P21 as an example, the area between the straight line containing the first edge B1 of the first pixel opening P21 and the area containing the second edge B2 is the first region Q1. The break part K is located in this first region Q1. Thus, along the extension direction of the first edge B1, the break part K will not overlap with the second color pixel opening P2. The amount of light emitted by the second color sub-pixel 12 that exits from the break part will be less, thereby reducing the problem of the metal mesh being visible at a large viewing angle due to light leakage from the second color sub-pixel 12 at the break part. Therefore, it is beneficial to improve the performance of the second color sub-pixel 12. Figure 14 The overall display effect of the display panel with the pixel arrangement structure shown.

[0099] Continue to refer to Figure 14 In an optional embodiment of the present invention, the metal mesh 22 includes a first metal line segment 223 and a second metal line segment 224, the first metal line segment 223 extending along a second direction D2 and the second metal line segment 224 extending along a first direction D1.

[0100] In this embodiment, the first color pixel opening P1, the second color pixel opening P2, and the third color pixel opening P3 all include an edge extending along the first direction D1 and an edge extending along the second direction D2. When a metal mesh-shaped touch electrode 21 is formed around the pixel opening, the first metal line segment 223 in the metal mesh is extended along the second direction D2, and the second metal line segment 224 is extended along the first direction D1. This is equivalent to wiring at least a portion of the metal line segments in the metal mesh along the periphery of the edge of the corresponding pixel opening, which helps to reduce the manufacturing process of the touch electrode 21 and improve the production efficiency of the display panel.

[0101] It should be noted that the pixel arrangement structure shown in the embodiments of the present invention is only illustrative and does not limit the actual pixel arrangement structure of the display panel in the present invention. The setting method of the disconnection part in the present invention is also applicable to other types of pixel structures.

[0102] Figure 5 , Figure 8 and Figure 14 The illustrated embodiment uses the edge of the pixel opening as a straight line segment and the line segments contained in the metal mesh as straight line segments as an example. The metal mesh is wired along the outer periphery of the pixel opening edge. In some other embodiments of the present invention, the shapes of the pixel opening and the metal mesh projected onto the display panel can also be different. When the pixel opening includes arc-shaped line segments, the corresponding metal mesh can also include arc-shaped line segments. For example, please refer to... Figure 7 In an optional embodiment of the present invention, the metal mesh 22 includes arcuate line segments.

[0103] When the shape of the pixel opening includes curved line segments, setting the corresponding line segments of the metal mesh surrounding the pixel opening as curved line segments can simplify the manufacturing process of the touch electrode and prevent the touch electrode from blocking the pixel opening.

[0104] Based on the same inventive concept, the present invention also provides a display device. Figure 15 The image shown is a top view of a display panel provided in an embodiment of the present invention, which includes the display panel provided in the above-described embodiment of the present invention.

[0105] It is understood that the display device provided in the embodiments of the present invention can be other display devices with display and touch functions, such as mobile phones, tablets, computers, televisions, and vehicle-mounted display devices, and the present invention does not impose specific limitations on them. The display device provided in the embodiments of the present invention has the beneficial effects of the display panel provided in the embodiments of the present invention. For details, please refer to the specific descriptions of the display panel in the above embodiments, which will not be repeated here.

[0106] As can be seen from the above embodiments, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0107] In the display panel and display device provided by this invention, a touch layer is disposed on one side of the display layer. The touch layer includes a plurality of mutually insulated touch electrodes. The display layer includes a plurality of pixel openings. The orthographic projection of the metal mesh in the touch electrodes onto the plane of the display panel is located outside the orthographic projection of the pixel openings onto the plane of the display panel. Adjacent touch electrodes are insulated from each other by a disconnection. The pixel openings include a first color pixel opening and a second color pixel opening. The area of ​​a second color pixel opening is smaller than the area of ​​the first color pixel opening. The human eye is more sensitive to the second color light. If the disconnection is disposed around the second color pixel opening, the light emitted by the second color sub-pixel is more likely to leak at the disconnection, resulting in the metal mesh being visible. When a disconnection is disposed between adjacent touch electrodes, the embodiments of this invention avoid the second color pixel opening as much as possible, reducing the amount of light emitted by the second color sub-pixel that is emitted through the disconnection. This helps to reduce or avoid the problem of the metal mesh being visible at large viewing angles, thus improving the display effect.

[0108] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
