The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted. The words expressing the position and direction described in the present invention are illustrated in the accompanying drawings, but may be changed as required and still be within the scope of the present invention. The drawings of the present invention are for illustrative purposes only and do not represent true scale.
It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
The following describes a display panel and a display device provided in an embodiment of the present invention with reference to the accompanying drawings.
The embodiment of the invention provides a touch display panel, which comprises a display substrate and a touch electrode positioned on the light emergent side of the display substrate;
as shown in fig. 1, fig. 1 is a schematic structural diagram of a display substrate according to an embodiment of the present invention; the display substrate 1 includes a substrate 10, and a plurality of pixels 11 and a plurality of signal traces 12 (not shown in fig. 1) located on one side of the substrate 10 facing the touch electrode 2;
the display substrate 1 includes a first display region a1 and a second display region a2, and the distribution density of the pixels 11 within the first display region a1 is smaller than the distribution density of the pixels 11 within the second display region a 2;
as shown in fig. 2 and 3, fig. 2 is a schematic view of a partial structure of a touch display panel in a first display area according to an embodiment of the present invention; 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 invention; the touch electrode includes 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 a 2;
as shown in fig. 4, fig. 4 is a schematic partial structure diagram of a first touch electrode in a touch display panel according to an embodiment of the present invention; the orthographic projection of the first touch electrode block 21 on the display substrate 1 at least covers the gap of the signal trace 12 between the adjacent pixels 11.
According to the touch display panel provided by the embodiment of the invention, the orthographic projection of the first touch electrode block on the display substrate at least covers the gap of the signal wire between the adjacent pixels. The first touch electrode block can be used for shielding light rays emitted to the gap of the signal wiring between adjacent pixels in the first display area, so that optical diffraction cannot occur at the gap of the signal wiring shielded by the first touch electrode block. In addition, as the gap of the signal wire between the adjacent pixels in the first display area is covered by the first touch electrode, compared with the method of separately manufacturing the light blocking strip for blocking the gap of the signal wire, the method does not need to increase the process steps and the thickness of the touch display panel.
In a specific implementation, in the touch display panel provided in the embodiment of the present invention, the relative position 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, when embodied. In the touch display panel provided by the embodiment of the invention, the first display area is generally a transparent display area because the pixel distribution density in the first display area is low, and a camera can be arranged in the first display area and 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 invention, the first touch electrode block can shield light rays emitted to the gap of the signal trace between adjacent pixels in the first display area, so that the optical diffraction does not occur at the gap of the signal trace shielded by the first touch electrode block, and the shooting effect of the camera is not influenced.
Alternatively, in the touch display panel provided in the embodiment of the present invention, 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 the gap of the signal trace 12 between the adjacent pixels 11 in the orthographic projection of the display substrate 1. Since the distribution density of the pixels in the first display region is low, the distribution density of the first electrode portions 211 surrounding the pixels 11 in the first touch electrode block 21 is correspondingly low, that is, the occupied area of the first touch electrode block in the first display region can be relatively reduced, so that the light transmittance of the first display region can be increased.
In specific implementation, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 5, fig. 5 is a schematic structural diagram of a second touch electrode in the touch display panel provided in the implementation of the present invention; 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 some panels, the pixels further include a yellow sub-pixel or a white sub-pixel in order to improve the display quality, and the disclosure is not limited herein.
In a specific implementation, in the touch display panel provided in the embodiment of the invention, in the first display area, as shown in fig. 5, the second touch electrode block 22 is in a grid-like 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 does not coincide with the light emitting region of each corresponding sub-pixel 110.
Further, in the touch display panel provided in the embodiment of the present invention, the smaller the number of sub-pixels corresponding to each grid of the second touch electrode block is, the more area is occupied by one second touch electrode block on the basis that the grid width is fixed, so that the touch sensitivity is higher.
Therefore, optionally, in the touch display panel provided in the embodiment of the present invention, in the first display area, as shown in fig. 5, the second touch electrode block 22 is in a grid-like structure, and each grid corresponds to at least one sub-pixel 110, so that a contact area between the second touch electrode block and a finger can be increased as much as possible, and an orthographic projection of the second touch electrode block 22 on the display substrate does not coincide with a light emitting area of each corresponding sub-pixel 110, and it can be ensured that the aperture ratio of the second display area is not affected by the second touch electrode block.
Optionally, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 6, fig. 6 is a schematic view of a partial structure of a first touch electrode block provided in another embodiment of the present invention; the first electrode portion 211 is of a grid-shaped structure, and each grid of the grid-shaped structure corresponds to one sub-pixel 110; the orthographic projection of the first electrode portion 211 on the display substrate does not coincide with the light emitting region of each corresponding sub-pixel 110. Similarly, the contact area between the first touch electrode block and the finger can be increased as much as possible, the orthographic projection of the first electrode part 211 on the display substrate does not coincide with the light emitting area of each corresponding sub-pixel 110, and the first electrode part 211 can be ensured not to influence the aperture ratio of the first display area.
In a specific implementation, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 7, fig. 7 is a schematic partial structure diagram of a first touch electrode block provided in another embodiment of the present invention; the plurality of signal traces include a plurality of first signal traces 121 extending along the row direction X and a plurality of second signal traces 122 extending along the column direction Y;
the plurality of second electrode portions includes 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;
each transverse electrode part 2121 covers the gap between at least two first signal traces 121 in the orthographic projection of the display substrate;
and/or the orthographic projection of each longitudinal electrode part 2122 on the display substrate covers the gap between at least two second signal 122 traces. In this way, the transverse electrode 2121 blocks the gap between the first signal traces 121 extending along the row direction X, and the longitudinal electrode 2122 blocks the gap between the second signal traces 122 extending along the column direction Y, so as to reduce the diffraction of the external light when irradiating the first display region as much as possible.
Further, in the touch display panel provided in the embodiment of the invention, in order to avoid that the second electrode part in the first touch electrode block cannot effectively block the gap between the signal traces when the touch electrodes are aligned with the display substrate, the width of the second electrode part may be set to be greater than the width of the gap between the signal traces, for example, as shown in fig. 7, the width w2 of the transverse electrode part 2121 is greater than the gap width w1 between the first signal traces 121.
Optionally, in the touch display panel provided in the embodiment of the present invention, the width of the second electrode portion is at least equal to the width of the gap between the covered signal traces plus the width of the alignment precision. 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, and therefore light irradiated on the first display area can not be diffracted.
In a specific implementation, in the touch display panel provided in the embodiment of the present invention, 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 area of the edges of the two adjacent touch electrode blocks is, the larger the corresponding mutual capacitance is.
Therefore, optionally, in the touch display panel provided in the embodiment of the invention, the facing area of the edge of each first touch electrode pad in the first display area is S1, and the facing area of the edge of each second touch electrode pad in the second display area is S2, where 0.99 ≦ S1/S2 ≦ 1.01. Since S1 and S2 are relatively close, it is equivalent to design the mutual capacitance between the first touch electrodes in the first display area to be substantially equal to the mutual capacitance between the second touch electrode blocks in the second display area, so as to reduce the difference between the touch performance in the first display area and the touch performance in the second display area, and thus the uniformity of the touch performance of the display panel is better.
Further, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 8, fig. 8 is a schematic diagram illustrating a boundary shape of a touch electrode block in the touch display panel provided in the embodiment of the present invention; the shape of the boundary of the edge of the first touch electrode block 21 is the same as the shape of the boundary 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 in the first display region is equal to the facing area S2 of the edge of each second touch electrode block 22 in the second display region.
Optionally, in the touch display panel provided in the embodiment of the present invention, 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. The width of the second electrode part 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 part can shield gaps between signal wires, and light irradiated on the first display area can not be diffracted.
Optionally, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 2, the touch electrode further includes:
the first bridge connection parts 23 of the first touch electrode blocks 21 adjacent in the column direction Y are connected, or the first bridge connection parts of the first touch electrode blocks adjacent in the row direction are connected;
as shown in fig. 9, fig. 9 is a schematic cross-sectional structure view of a touch display panel according to an embodiment of the invention; the first bridge connection portion 23 is disposed in a different layer from the first touch electrode block 21, and the first bridge connection portion 23 is electrically connected to the first touch electrode block 21 through a via hole.
In the touch display panel provided in the embodiment of the present invention, the touch electrode includes the two layers of metal, namely the touch electrode block and the bridging connection portion, so that, in specific implementation, a gap of the signal trace can be shielded by the metal layer of the touch electrode block, or by the metal layer of the bridging connection portion, or by the two layers of metal layers of the touch electrode block and the bridging connection portion, which is determined specifically according to actual conditions, and is not limited herein.
Optionally, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 10, fig. 10 is a schematic cross-sectional structure diagram of a touch display panel provided in another embodiment of the present invention; the second electrode portion 212 includes a first sub-electrode 001 and a second sub-electrode 002 that are electrically connected;
the orthographic projections of the first sub-electrode 001 and the second sub-electrode 002 on the display substrate at least cover the gaps of the signal wires 12 between the 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.
When the touch screen is specifically implemented, the first sub-electrode and the second sub-electrode are used for shielding 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 gap of the signal wiring is shielded by combining the second sub-electrode and the first sub-electrode on the basis of ensuring the consistent metal line width of the touch electrode block layer. In addition, the second sub-electrodes can be partially overlapped with the first sub-electrodes, that is, the area of the second sub-electrodes is increased by the overlapped part of the second sub-electrodes with the first sub-electrodes, so that the resistance of the first touch electrode block can be reduced, and the transmittance of light is not affected.
Further, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 11, fig. 11 is a schematic cross-sectional structure diagram of a touch display panel provided in another embodiment of the present invention; the orthographic 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 in alignment dislocation, the second electrode part can still shield the gap between the signal wires, and therefore light irradiated on the first display area can not be 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 in the embodiment of the present invention, the second sub-electrode multiplexes the first alignment mark. Namely, the second sub-electrode is used as the alignment mark, so that the manufacturing process can be simplified.
Further, in the touch display panel provided in the embodiment of the present invention, as shown in fig. 12, fig. 12 is a schematic structural diagram of a touch display panel provided in another embodiment of the present invention; 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 first metal blocks 13 disposed at the same layer as the first touch electrode blocks 21 or at the same layer as the first bridge connection parts 23 (shown by dotted lines), the first metal blocks 13 multiplexing a second alignment mark. Therefore, a process for manufacturing the alignment mark does not need to be added independently, and the second alignment mark can be formed when the first touch electrode block or the first bridging connection part is formed only by modifying the graph of the layer where the first touch electrode block or the first bridging connection part is located.
In a specific implementation, the pattern of the second alignment mark may be a character, a cross, a Chinese character 'mi', or the like, and is not limited herein.
Optionally, in the touch display panel provided in the embodiment of the invention, in a unit area, a ratio of an area occupied by the first touch electrode block to an area occupied by the second touch electrode block is 0.9 to 1.1, which is not limited herein. In specific implementation, the closer the area occupied by the first touch electrode block and the area occupied by the second touch electrode block are, 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 in the embodiment of the present invention, 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.
Optionally, in the touch display panel provided in the embodiment of the present invention, an encapsulation layer covering the pixels and the traces is further included;
the touch electrode is positioned on one side of the packaging layer facing the substrate base plate, namely the touch display panel is an in-cell touch screen.
Or the touch electrode is positioned on one side of the packaging layer, which is far away from the substrate, namely the touch display panel is an on-cell touch screen.
Based on the same inventive concept, an embodiment of the present invention further provides a display device, including any one of the touch display panels provided in the embodiments of the present invention. Since the principle of the display device for solving the problems is similar to that of the touch display panel, the implementation of the display device can be referred to that of the touch display panel, and repeated descriptions are omitted.
In a specific implementation, the display device may be: any product or component with a display function, such as a mobile phone, a tablet computer, a notebook computer, etc., as shown in fig. 13. The display device can be implemented by referring to the above embodiments of the display panel, and repeated descriptions are omitted.
According to the touch display panel and the display device provided by the embodiment of the invention, the orthographic projection of the first touch electrode block on the display substrate at least covers the gap of the signal routing wire between the adjacent pixels. The first touch electrode block can be used for shielding light rays emitted to the gap of the signal wiring between adjacent pixels in the first display area, so that optical diffraction cannot occur at the gap of the signal wiring shielded by the first touch electrode block. In addition, as the gap of the signal wire between the adjacent pixels in the first display area is covered by the first touch electrode, compared with the method of separately manufacturing the light blocking strip for blocking the gap of the signal wire, the method does not need to increase the process steps and the thickness of the touch display panel.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention.
