Therefore, the present application is not limited by the specific embodiments disclosed below. The description hereinafter sets forth a preferred embodiment for practicing the application, but is not intended to limit the scope of the application, as the description is given for the purpose of illustrating the general principles of the application. The scope of the application is defined by the appended claims.
The display panel and the display device provided by the embodiment of the application are specifically described below with reference to the accompanying drawings.
The embodiment of the application provides a touch display panel, which comprises a display substrate and a touch electrode positioned on the light emitting side of the display substrate;
fig. 1 is a schematic structural diagram of a display substrate according to an embodiment of the application; the display substrate 1 includes a substrate 10, a plurality of pixels 11 and a plurality of signal traces 12 (not shown in fig. 1) on a side of the substrate 10 facing the touch electrode 2;
the display substrate 1 includes a first display area A1 and a second display area A2, and the distribution density of the pixels 11 in the first display area A1 is smaller than the distribution density of the pixels 11 in the second display area A2;
fig. 2 and fig. 3 are schematic views of a partial structure of a touch display panel in a first display area according to an embodiment of the present application; fig. 3 is a schematic partial structure diagram of a touch display panel in a second display area according to an embodiment of the present application; the touch electrode comprises a plurality of first touch electrode blocks 21 positioned in the first display area A1 and a plurality of second touch electrode blocks 22 positioned in the second display area A2;
fig. 4 is a schematic diagram of a partial structure of a first touch electrode in a touch display panel according to an embodiment of the application; the front projection of the first touch electrode block 21 on the display substrate 1 at least covers the gaps of the signal traces 12 between the adjacent pixels 11.
In the touch display panel provided by the embodiment of the application, the front projection of the first touch electrode block on the display substrate at least covers the gap of the signal wire between the adjacent pixels. Light rays which are emitted to the gaps of the signal wires between adjacent pixels in the first display area can be shielded by the first touch electrode block, so that optical diffraction cannot occur at the gaps of the signal wires shielded by the first touch electrode block. In addition, as the gaps of the signal wires between the adjacent pixels in the first display area are covered by the first touch electrode, compared with the method for independently manufacturing the light blocking strips for shielding the gaps of the signal wires, the method has the advantages that the process steps are not increased, and in addition, the thickness of the touch display panel is not increased.
In a specific implementation, in the touch display panel provided by the embodiment of the present application, the relative positional relationship between the first display area and the second display area is not limited, for example, the first display area may be surrounded by the second display area, or the first display area is located at one side of the second display area, or the first display area is partially surrounded by the second display area, which is not limited herein.
Further, in the specific implementation. In the touch display panel provided by the embodiment of the application, the pixel distribution density in the first display area is low, so that the display panel is generally a transparent display area, a camera can be arranged in the first display area, and the camera can capture images through the first display area, so that a shooting function is realized. In the touch display panel provided by the embodiment of the application, the first touch electrode block can shield the light rays which are emitted to the gap of the signal wiring between the adjacent pixels in the first display area, so that the optical diffraction can not occur at the gap of the signal wiring shielded by the first touch electrode block, and the shooting effect of the camera can not be influenced.
Alternatively, in the touch display panel provided by the embodiment of the application, as shown in fig. 4, the first touch electrode block 21 includes first electrode portions 211 surrounding each pixel 11, and second electrode portions 212 located between adjacent first electrode portions 211 and electrically connected to the first electrode portions 211; the second electrode portion 212 covers at least a gap of the signal trace 12 between the adjacent pixels 11 in the front projection of the display substrate 1. Since the distribution density of the pixels is low in the first display area, the distribution density of the first electrode portions 211 surrounding each pixel 11 in the first touch electrode block 21 is correspondingly low, that is, the occupied area of the first touch electrode block can be relatively reduced in the first display area, so that the light transmittance of the first display area can be increased.
In a specific implementation, in the touch display panel provided by the embodiment of the present application, as shown in fig. 5, fig. 5 is a schematic structural diagram of a second touch electrode in the touch display panel provided by the embodiment of the present application; the pixel 11 includes at least three sub-pixels 110, for example, a red sub-pixel, a blue sub-pixel, and a green sub-pixel including three primary colors. Of course, in order to improve the display quality, in some panels, the pixels further include a yellow sub-pixel, a white sub-pixel, or the like, which is not limited herein.
In a specific implementation, in the touch display panel provided by the embodiment of the present application, in the first display area, as shown in fig. 5, the second touch electrode block 22 is in a grid structure, and each grid corresponds to at least one sub-pixel 110;
the orthographic projection of the second touch electrode block 22 on the display substrate is not overlapped with the light emitting area of the corresponding sub-pixels 110.
Further, in the touch display panel provided by the embodiment of the application, the smaller the number of sub-pixels corresponding to each grid of the second touch electrode block, the larger the area occupied by one second touch electrode block on the basis of fixed grid width, so that the higher the touch sensitivity.
Therefore, in the touch display panel provided by the embodiment of the application, in the first display area, as shown in fig. 5, the second touch electrode block 22 is in a grid structure, and each grid corresponds to at least one sub-pixel 110, so that the contact area between the second touch electrode block and a finger can be increased as much as possible, and the orthographic projection of the second touch electrode block 22 on the display substrate does not coincide with the corresponding light emitting area of each sub-pixel 110, and the aperture ratio of the second display area can be ensured not to be affected by the second touch electrode block.
Optionally, in the touch display panel provided by the embodiment of the present application, as shown in fig. 6, fig. 6 is a schematic partial structure diagram of a first touch electrode block provided by another embodiment of the present application; the first electrode portion 211 has a grid structure, and each grid of the grid structure corresponds to one sub-pixel 110; the front projection of the first electrode portion 211 on the display substrate does not overlap the light emitting region of each corresponding sub-pixel 110. In the same way, the contact area between the first touch electrode block and the finger can be increased as much as possible, and the orthographic projection of the first electrode portion 211 on the display substrate does not overlap with the corresponding light emitting area of each sub-pixel 110, and the opening ratio of the first display area can be ensured not to be affected by the first electrode portion 211.
In particular, in the touch display panel provided by the embodiment of the present application, as shown in fig. 7, fig. 7 is a schematic partial structure of a first touch electrode block provided by another embodiment of the present application; the plurality of signal traces includes a plurality of first signal traces 121 extending in the row direction X and a plurality of second signal traces 122 extending in the column direction Y;
the plurality of second electrode portions include a plurality of lateral electrode portions 2121 extending in the row direction X and a plurality of longitudinal electrode portions 2122 extending in the column direction Y;
the front projection of each transverse electrode 2121 on the display substrate covers the gap between at least two first signal traces 121;
and/or each longitudinal electrode 2122 covers a gap between at least two traces of the second signal 122 in an orthographic projection of the display substrate. In this way, the gaps between the first signal traces 121 extending in the row direction X are blocked by the lateral electrode portions 2121, and the gaps between the second signal 122 traces extending in the column direction Y are blocked by the longitudinal electrode portions 2122, so that the diffraction of external light when the first display region is irradiated is reduced as much as possible.
Further, in the touch display panel provided by the embodiment of the application, in order to avoid that the second electrode portion in the first touch electrode block cannot effectively shield the gap between the signal wires when the touch electrode is aligned with the display substrate, the width of the second electrode portion may be set to be greater than the width of the gap between the signal wires, for example, as shown in fig. 7, the width w2 of the transverse electrode portion 2121 is greater than the gap width w1 between the first signal wires 121.
Optionally, in the touch display panel provided by the embodiment of the application, a width of the second electrode portion is at least equal to a width of a gap between the covered signal traces plus an alignment accuracy width. Therefore, even when the touch electrode and the display substrate are in alignment dislocation, the second electrode part can still shield the gap between the signal wires, so that the light rays irradiated in the first display area are ensured not to be diffracted.
In a specific implementation, in the touch display panel provided by the embodiment of the application, the touch electrode block is the smallest touch unit, the edges of any two adjacent touch electrode blocks form a mutual capacitance, and the larger the facing areas of the edges of the two adjacent touch electrode blocks are, the larger the corresponding mutual capacitance is.
Therefore, optionally, in the touch display panel provided by the embodiment of the application, the facing area of the edge of each first touch electrode block located in the first display area is S1, and the facing area of the edge of each second touch electrode block located in the second display area is S2, where S1/S2 is greater than or equal to 0.99 and less than or equal to 1.01. Because S1 and S2 are relatively close, the mutual capacitance between the first touch electrodes in the first display area is designed to be approximately equal to the mutual capacitance between the second touch electrode blocks in the second display area, and the difference between the touch performance in the first display area and the touch performance in the second display area is reduced, so that the uniformity of the touch performance of the display panel is better.
Further, in the touch display panel provided by the embodiment of the application, as shown in fig. 8, fig. 8 is a schematic diagram of a boundary shape of a touch electrode block in the touch display panel provided by the embodiment of the application; the boundary shape of the edge of the first touch electrode block 21 is the same as the boundary shape of the edge of the second touch electrode block 22. Thereby ensuring that the facing area S1 of the edge of each first touch electrode block 21 located in the first display area is equal to the facing area S2 of the edge of each second touch electrode block 22 located in the second display area.
Optionally, in the touch display panel provided by the embodiment of the application, a grid line width of the second touch electrode block is smaller than a width of the second electrode portion of the first touch electrode block. That is, the width of the second electrode portion of the first touch electrode block is set to be larger than the grid line width of the second touch electrode block, so that the second electrode portion can shield gaps between signal wires, and therefore light rays irradiated in the first display area are prevented from being diffracted.
Optionally, in the touch display panel provided by the embodiment of the present application, as shown in fig. 2, the touch electrode further includes:
first bridging connection parts 23 connecting the first touch electrode blocks 21 adjacent in the column direction Y, or first bridging connection parts connecting the first touch electrode blocks adjacent in the row direction;
fig. 9 is a schematic cross-sectional view of a touch display panel according to an embodiment of the application; the first bridging connection part 23 is arranged in different layers with the first touch electrode block 21, and the first bridging connection part 23 is electrically connected with the first touch electrode block 21 through a via hole.
In the touch display panel provided by the embodiment of the application, since the touch electrode comprises the touch electrode block and the bridging connection part, the gap of the signal wiring can be shielded by the metal layer of the touch electrode block or the bridging connection part in specific implementation, and of course, the two metal layers of the touch electrode block and the bridging connection part can be shielded, which is determined according to practical situations and is not limited herein.
Optionally, in the touch display panel provided by the embodiment of the present application, as shown in fig. 10, fig. 10 is a schematic cross-sectional structure of a touch display panel provided by another embodiment of the present application; the second electrode portion 212 includes a first sub-electrode 001 and a second sub-electrode 002 electrically connected;
the front projection of the first sub-electrode 001 and the second sub-electrode 002 on the display substrate at least covers the gap of the signal wiring 12 between adjacent pixels;
the first sub-electrode and the first touch electrode block are arranged on the same layer, and the second sub-electrode and the first bridging connection part are arranged on the same layer.
In the implementation, the first sub-electrode and the second sub-electrode are utilized to shield the gap of the signal wiring, so that the line width of the first sub-electrode is the same as the grid line width of the second touch electrode block, namely, the combination of the second sub-electrode and the first sub-electrode is utilized to shield the gap of the signal wiring on the basis of ensuring the consistent metal line width of the touch electrode block layer. In addition, the second sub-electrode and the first sub-electrode may be partially overlapped, that is, the area of the second sub-electrode is increased by using the portion of the second sub-electrode overlapped with the first sub-electrode, so that not only the resistance of the first touch electrode block may be reduced, but also the transmittance of light may not be affected.
Further, in the touch display panel provided by the embodiment of the application, as shown in fig. 11, fig. 11 is a schematic cross-sectional structure of a touch display panel provided by another embodiment of the application; the front projection of the second sub-electrode 002 on the display substrate covers the gap of the signal trace 12 located at the gap of the adjacent first touch electrode block. Therefore, when the touch electrode and the display substrate are prevented from being in alignment dislocation, the second electrode part can still shade gaps between the signal wires, and therefore light rays irradiated in the first display area are prevented from being diffracted.
In a specific implementation, in order to improve the alignment accuracy of the touch display panel, an alignment mark needs to be manufactured, and optionally, in the touch display panel provided by the embodiment of the application, the second sub-electrode multiplexes the first alignment mark. Namely, the second sub-electrode is used as an alignment mark, so that the manufacturing process can be simplified.
Further, in the touch display panel provided by the embodiment of the application, as shown in fig. 12, fig. 12 is a schematic structural diagram of a touch display panel provided by another embodiment of the application; the display substrate 1 includes a non-display area B surrounding the first display area A1 and the second display area A2, the non-display area B including a first metal block 13 disposed in the same layer as the first touch electrode block 21 or in the same layer as the first bridge connection portion 23 (shown by a dotted line in the figure), the first metal block 13 multiplexing the second alignment mark. Therefore, a process for manufacturing the alignment mark is not required to be added separately, and the second alignment mark can be formed when the first touch electrode block or the first bridge connecting part is formed only by modifying the pattern of the layer where the first touch electrode block or the first bridge connecting part is located.
In the specific implementation, the pattern of the second alignment mark may be a pattern such as a one-type pattern, a cross-type pattern, or a rice-type pattern, which is not limited herein.
Optionally, in the touch display panel provided by the embodiment of the present application, a ratio of an area occupied by the first touch electrode block to an area occupied by the second touch electrode block is between 0.9 and 1.1 in a unit area, which is not limited herein. In the implementation, the closer the area occupied by the first touch electrode block is to the area occupied by the second touch electrode block, the more consistent the touch performance of the first display area and the second display area is. Therefore, optionally, in the touch display panel provided by the embodiment of the present application, in a unit area, an area occupied by the first touch electrode block is equal to an area occupied by the second touch electrode block.

Based on the same inventive concept, the embodiment of the application also provides a display device, which comprises any one of the touch display panels provided by the embodiment of the application. Because the principle of the display device for solving the problem is similar to that of the touch display panel, the implementation of the display device can be referred to the implementation of the touch display panel, and the repetition is omitted.
