It should be noted that, as can be seen from fig. 2 and 3, the element layer 114 corresponding to the region K includes a sub-pixel unit U. In the present embodiment, the sub-pixel unit U can be any sub-pixel unit known to one of ordinary skill in the art, so the detailed structures of the active device T, the scan line SL, the data line DL, and the like are omitted, and the pixel electrode P shown in fig. 3 is only an example of the pixel electrode P, and is not used to limit the structure of the pixel electrode P.
Referring to fig. 3, the active device T may be electrically connected to the scan line SL and the data line DL. In the present embodiment, the active device T may be a thin film transistor, for example, which includes a gate, a channel layer, a drain and a source, wherein a gate insulating layer is disposed between the gate and the source and the drain, and a channel layer is disposed between the gate insulating layer and the source and the drain.

The extending direction of the scan line SL is different from the extending direction of the data line DL, and preferably, the extending direction of the scan line SL is substantially perpendicular to the extending direction of the data line DL. In addition, the scan line SL and the data line DL are located on different layers and are electrically insulated from each other.

However, the present invention is not limited thereto, and in other embodiments, for example (but not limited to): an alloy, a nitride of a metal material, an oxide of a metal material, an oxynitride of a metal material, or other conductive materials, or a stack of a metal material and the other conductive materials.
As shown in fig. 1, the opposite substrate 120 is disposed opposite to the pixel array substrate 110. The opposite substrate 120 can be any opposite substrate known to those skilled in the art for touch display panels. For example, in one embodiment, the opposite substrate 120 may include a blank substrate and a device layer on the blank substrate. For example, in one embodiment, the device layer included in the opposite substrate 120 may include, for example, a color filter layer, a wavelength conversion layer, a light-shielding pattern layer, an opposite electrode layer, or a combination thereof, but is not limited thereto and may be adjusted and changed as needed.
As shown in fig. 1, the display medium 130 is located between the pixel array substrate 110 and the opposite substrate 120. In this embodiment, the display medium 130 may be a liquid crystal material. In other words, the touch display panel 10 may be a touch liquid crystal display panel. However, the present invention is not limited thereto. In other embodiments, the display medium 130 may also be other display materials, such as organic light emitting material (organic light emitting material), inorganic light emitting diode (inorganic light emitting material), electrophoretic display material (electrophoretic display material), or plasma display material (plasma display material). Therefore, the touch display panel 10 may also be a touch organic light emitting display panel, a touch inorganic light emitting display panel, a touch electrophoretic display panel or a touch plasma display panel. The detailed display materials and panel structures are well known to any person skilled in the art, and the relevant description is omitted herein.
Referring to fig. 2, in the present embodiment, the touch electrode layer 140 includes at least one touch serial L1 and at least one touch serial L2. The extending direction of the touch serial L1 is different from the extending direction of the touch serial L2, and preferably, the extending direction of the touch serial L1 is substantially perpendicular to the extending direction of the touch serial L2. In addition, the touch serial L1 and the touch serial L2 are electrically insulated from each other.
In detail, in the present embodiment, the touch serial L1 includes a plurality of touch electrodes TP and a plurality of bridge portions B1, and each bridge portion B1 is electrically connected to two adjacent touch electrodes TP; the touch serial L2 includes a plurality of touch electrodes TP and a plurality of bridge portions B2, and each bridge portion B2 is electrically connected to two adjacent touch electrodes TP. That is, in the present embodiment, the touch electrode layer 140 includes a plurality of touch electrodes TP. It should be noted that although fig. 2 shows a touch serial L1 and a touch serial L2, the invention is not limited thereto. In other embodiments, the number of the touch serial L1 and the touch serial L2 may be multiple, depending on the size of the actual panel.
Referring to fig. 1 and fig. 2, each touch electrode TP in the touch electrode layer 140 completely overlaps with the plurality of sub-pixel units U in the display panel 100 in the vertical projection direction. Herein, the perpendicular projection direction is defined as a normal direction of the substrate 112. In this context, complete overlap is defined as follows: if the first object and the second object are completely overlapped, it means that the vertical projection of the first object is completely located within or overlapped with the vertical projection of the second object. Further, referring to fig. 2 to 4, the device layer 114 corresponding to the region K includes a sub-pixel unit U, and the touch electrode layer 140 corresponding to the region K includes a unit region X. That is, in the present embodiment, one unit region X overlaps one sub-pixel unit U in the vertical projection direction. In detail, in the present embodiment, the unit area X and the corresponding sub-pixel unit U are disposed to be completely overlapped. As described above, each touch electrode TP completely overlaps with the plurality of sub-pixel units U in the vertical projection direction, so each touch electrode TP includes a plurality of unit areas X.
On the other hand, each unit region comprises a plurality of slit regions, and each slit region is provided with at least one slit. In this embodiment, when each three sub-pixel units U may constitute one pixel unit in the element layer 114, each unit region X includes three slit regions R1-R3, wherein the slit region R1 may have a slit S1 therein, the slit region R2 has a slit S2 therein, and the slit region R3 has a slit S3 therein. In another embodiment, each unit region X includes four slit regions (not shown), for example, when every four sub-pixel units U can constitute one pixel unit in the device layer 114, for example. In other words, each unit region X includes, for example, N slit regions, while every N sub-pixel units U may constitute, for example, one pixel unit in the element layer 114. However, the present invention is not limited thereto. In other embodiments, the number of slit regions included in each unit region X may be adjusted according to the relative size relationship between the unit region X and the slit region. In the present embodiment, the slit S1 has an extending direction d1, the slit S2 has an extending direction d2, and the slit S3 has an extending direction d 3. In addition, in the present embodiment, each cell region X may have a rectangular shape, and each of the slit regions R1 to R3 may have a square shape. However, the present invention is not limited thereto. In other embodiments, each of the slit regions R1 to R3 may also be rectangular in shape. Details of the design of the slit regions R1 to R3 will be described below with reference to fig. 5. It should be noted that fig. 5 illustrates the slit region R1 as an example, and the details of the slit region R2 and the slit region R3 can be understood by those skilled in the art according to the following description of the slit region R1.
Referring to fig. 4 and 5, in the present embodiment, the slit region R1 has a side RS1 and a side RS2 opposite to each other and disposed oppositely to each otherSide RS3 and side RS 4. In detail, in the present embodiment, the sides RS1 to RS4 of the slit region R1 have the same length a, and the diagonal length of the slit region R1 is c, where a and c satisfy the following relation:
on the other hand, in the present embodiment, the length a of the sides RS1 to RS4 is the same as the width a of the sub-pixel unit U. However, the present invention is not limited thereto. In other embodiments, the length a may also be greater or less than the width a. Specifically, as long as the length a and the width a satisfy the following relationship: a ═ a (1 ± 10%), is within the scope of the invention.
In the present embodiment, the edge of the slit S1 does not go beyond the edge of the slit region R1. In addition, in the present embodiment, the length b of the slit S1 and the diagonal length c of the slit region R1 may satisfy the following relational expression: b >0.5 c. That is, in the present embodiment, the length b of the slit S1 is at least longer than half of the diagonal length c.
In addition, in the present embodiment, an angle θ is formed between the extending direction d1 of the slit S1 and the extending direction d4 of the side RS 1. Specifically, in the present embodiment, the angle θ is, for example, 45 degrees. However, the present invention is not limited thereto. In other embodiments, the included angle θ can be adjusted between greater than 0 degrees and less than 90 degrees according to the actual requirements of product design, and when the included angle θ is between 0 degrees and 90 degrees, the slit S1 can be prevented from being perpendicular or parallel to one of the scan line SL or the data line DL, so as to reduce the display Mura phenomenon of the display screen. In addition, although the included angle θ is defined by the extending direction d1 of the slit S1 and the extending direction d4 of the side RS1, the invention is not limited thereto. In other embodiments, the included angle θ may be defined by the extending direction d1 of the slit S1 and the extending direction of the side RS2, or defined by the extending direction d1 of the slit S1 and the extending direction of the side RS3, or defined by the extending direction d1 of the slit S1 and the extending direction of the side RS 4. That is, the included angle θ can be defined by the extending direction d1 of the slit S1 and the extending direction of one of the sides RS 1-RS 4 of the slit region R1.
In the present embodiment, the slit S1 has a strip shape, for example. However, the present invention is not limited thereto. In other embodiments, the shape of the slit S1 may be, for example, an arc, a needle, an ellipse, a polygon, a dendrite, or a wave.
In addition, based on the above description of the slit region R1, it can be understood by those skilled in the art that there is an angle between the extending direction d2 of the slit S2 and the extending direction of one of the four sides of the slit region R2, and between the extending direction d3 of the slit S3 and the extending direction of one of the four sides of the slit region R3, respectively. Further, in the present embodiment, the angle θ between the extending direction d1 of the slit S1 and the extending direction d4 of the side RS1, the angle between the extending direction d2 of the slit S2 and the extending direction of one side of the slit region R2, and the angle between the extending direction d3 of the slit S3 and the extending direction of one side of the slit region R3 are, for example, the same as each other. In the present embodiment, an angle between the extending direction d2 of the slit S2 and the extending direction of one side of the slit region R2 is, for example, 45 degrees, and an angle between the extending direction d3 of the slit S3 and the extending direction of one side of the slit region R3 is, for example, 45 degrees. In the present embodiment, the extending directions d1 to d3 of the slits S1 to S3 and the extending direction of one of the sides of the slit region R1 to R3 have the same angle. In addition, in the present embodiment, the included angle θ may also be defined by the extending direction d1 of the slit S1 and the extending direction of one side of the slit region R2 or the slit region R3.
It should be noted that, in the touch display panel 10, one of the plurality of cell areas X included in the touch electrode layer 140 overlaps one of the plurality of sub-pixel units U included in the display panel 100 in a vertical projection direction, each of the cell areas X includes, for example, slit areas R1 to R3, and the slit areas R1 to R3 may have slits S1 to S3, respectively, so that compared with the conventional touch display panel, the difference in light transmittance of the touch display panel 10 at different positions is reduced, thereby contributing to improving the problem of uneven display of the image and enabling the touch display panel 10 to have good display quality.
In addition, as can be seen from fig. 2, the sub-pixel units U adjacent to the edge of each touch electrode TP and the adjacent edge of the corresponding touch electrode TP do not completely overlap in the vertical projection direction. That is, the complete sub-pixel unit does not completely overlap with the portion of the touch electrode TP adjacent to the edge. Based on this, in the portion adjacent to the edge of the touch electrode TP, the slit may be set or not set according to the area overlapped with the corresponding sub-pixel unit U. In detail, based on the above description of the slit regions R1-R3, it can be understood by those skilled in the art that slits can be provided if the overlapping area of the adjacent edge portion of the touch electrode TP and the corresponding sub-pixel unit U is enough to divide the slit region.
In the embodiment of fig. 4 and 5, the extending direction d1 of the slit S1, the extending direction d2 of the slit S2, and the extending direction d3 of the slit S3 are, for example, parallel to each other. That is, each of the slit regions R1, R2, and R3 has one slit S1, S2, and S3 therein, and the extending directions of the slits in two adjacent slit regions are, for example, parallel to each other. However, the present invention is not limited thereto. Hereinafter, other modifications will be described in detail with reference to fig. 6. It should be noted that the following embodiments follow the reference numerals and some contents of the foregoing embodiments, wherein the same or similar reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted portions, reference may be made to the foregoing embodiments, and the following embodiments will not be described in detail.
Fig. 6 is a schematic top view of a corresponding area K of the touch electrode layer in another embodiment of fig. 2. The embodiment of fig. 6 is similar to the embodiment of fig. 4 described above, and therefore, only the main differences from each other will be described below.
Referring to fig. 6, in the present embodiment, in the region K, the extending direction d1 of the slit S1 and the extending direction d2 of the slit S2 are staggered with each other, and the extending direction d2 of the slit S2 and the extending direction d3 of the slit S3 are staggered with each other. In other words, each of the slit regions R1, R2, R3 may have one slit S1, S2, S3 therein, and the extending directions of the slits in two adjacent slit regions are staggered with each other, for example. That is, in the touch display panel 10, the orientations of the extending directions d1 to d3 of the slits S1 to S3 may not be completely the same as long as the extending directions d1 to d3 of the slits S1 to S3 and the extending direction of one of the side edges of one of the slit regions R1 to R3 have the same included angle, so as to reduce the difference of the light penetration degrees at different positions. Specifically, in the present embodiment, the orientation of the extending direction d1 of the slit S1 is the same as the orientation of the extending direction d3 of the slit S3, and the orientation of the extending direction d2 of the slit S2 is different from the orientation of the extending direction d1 of the slit S1 and the orientation of the extending direction d3 of the slit S3.
In the embodiment of fig. 4 and 5, the slit regions R1 to R3 each have one slit (i.e., the slit S1, the slit S2, and the slit S3). However, the present invention is not limited thereto. In another embodiment, the slit regions R1 to R3 may have a plurality of slits therein. Hereinafter, other modifications will be described in detail with reference to fig. 7. It should be noted that the following embodiments follow the reference numerals and some contents of the foregoing embodiments, wherein the same or similar reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted portions, reference may be made to the foregoing embodiments, and the following embodiments will not be described in detail.
Fig. 7 is a schematic top view of a corresponding area K of the touch electrode layer in another embodiment of fig. 2. The embodiment of fig. 7 is similar to the embodiment of fig. 4 described above, and therefore, only the main differences from each other will be described below.
Referring to fig. 7, in the present embodiment, in the region K, the slit region R1 has the slit S1 and the slit S4 staggered with each other, the slit region R2 has the slit S2 and the slit S5 staggered with each other, and the slit region R3 has the slit S3 and the slit S6 staggered with each other. That is, in the present embodiment, the slit regions R1 to R3 have two slits respectively and intersect with each other.
On the other hand, as described above with respect to the extending directions d1 to d3 of the slits S1 to S3, it can be understood by those skilled in the art that the included angles between the extending directions of the slits S4 to S6 and the extending direction of one of the sides of the slit regions R1 to R3 are substantially the same as the included angles between the extending directions d1 to d3 of the slits S1 to S3 and the extending direction of one of the sides of the slit regions R1 to R3, so as to reduce the difference of the light penetration degrees at different positions.
It should be noted that, in the touch display panel 10, one of the plurality of cell areas X included in the touch electrode layer 140 overlaps one of the plurality of sub-pixel units U included in the display panel 100 in the vertical projection direction, each of the cell areas X includes slit areas R1 to R3, and the slit areas R1 to R3 respectively have a plurality of slits, for example, two slits, so that the difference of light transmittance at different positions of the touch display panel 10 is reduced compared with the conventional touch display panel, thereby being beneficial to improving the problem of uneven image display and enabling the touch display panel 10 to have good display quality.
In summary, in the touch display panel of the present invention, one of the plurality of cell areas included in the touch electrode layer on the display panel is overlapped with one of the plurality of sub-pixel units included in the display panel in the vertical projection direction, and each cell area includes a plurality of slit areas having at least one slit therein, so that the difference of light transmittance at different positions of the touch display panel of the present invention is reduced compared with the conventional touch display panel, thereby contributing to improving the problem of uneven display of images and providing the touch display panel of the present invention with good display quality.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
