It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a schematic view of a display panel according to an embodiment of the present invention. As shown in fig. 1, the display panel includes: the display area AA surrounds the non-display area BA; the display panel provided by the invention is provided with a non-display area BA in a display area AA, a camera and other devices can be arranged in the non-display area BA, the display panel also comprises a touch electrode layer 10, the touch electrode layer comprises a plurality of touch electrodes 10C arranged in an array, the touch electrodes 10C comprise first touch electrodes 10C1, and at least one first touch electrode 10C1 is at least partially overlapped with the non-display area BA in the direction vertical to the display panel.
It should be noted that fig. 1 only illustrates an embodiment in which the plurality of first touch electrodes 10C1 respectively overlap with a portion of the non-display area BA. In other alternative embodiments of the invention, one first touch electrode 10C1 may be overlapped with all the non-display areas BA, and the description of the invention is omitted. The shape of the non-display area in fig. 1 is only schematically illustrated, and is not intended to limit the present invention, and the non-display area may be any shape such as a rectangle, a triangle, or a polygon. It should be noted that the non-display area defined in the present invention is an area surrounded by the display area, and is not a frame non-display area surrounding the display area, which is conventionally understood.
In a display panel provided with touch electrodes, a display area is generally divided into touch areas with approximately equal areas, and one touch electrode is arranged in one touch area, so that the touch function of the display area of the display panel can be realized on the whole surface. For a display panel with an opening in the display area (i.e., a non-display area is disposed in the display area), the display area is in an incomplete shape, and when the touch electrodes are disposed, the touch electrodes are not disposed at the opening position due to the fact that the opening position does not need a touch function. The display panel is provided with the non-display area in the display area, the touch electrodes comprise the first touch electrodes, at least one first touch electrode is at least partially overlapped with the non-display area, and the touch electrodes are also arranged in the non-display area of the display panel.
In some optional embodiments, the area of each of the first touch electrodes is the same. According to the embodiment, the areas of the first touch electrodes overlapped with the non-display area are equal, so that the touch modulus of the first touch electrodes overlapped with the non-display area is the same in the touch stage, and the reliability of the touch performance is ensured. In addition, the areas of the first touch electrodes overlapped with the non-display area are equal, and the first touch electrodes can execute the same operation rule to realize touch detection, so that the operation amount of the touch detection is simplified.
In an embodiment, fig. 2 is a schematic diagram of an alternative implementation manner of a display panel according to an embodiment of the present invention. As shown in fig. 2, the touch electrode 10C further includes a second touch electrode 10C2, the second touch electrode 10C2 does not overlap with the non-display area BA, and the area of the second touch electrode 10C2 is the same as the area of the first touch electrode 10C 1.
In the display panel provided by the embodiment, at least one first touch electrode is at least partially overlapped with the non-display area, so that the difference in the area between the first touch electrode overlapped with the non-display area and the touch electrode at other positions of the display area can be reduced, and the difference in the touch modulus of each touch electrode in the display panel can be reduced. In addition, the second touch electrode is not overlapped with the non-display area, the area of the second touch electrode is equal to that of the first touch electrode, the touch modulus of the second touch electrode is the same as that of the first touch electrode, the second touch electrode and the first touch electrode can execute the same operation rule to realize touch detection, and the simplification of the operation amount of the touch detection is facilitated.
Fig. 2 only schematically illustrates a case where the corners of the display panel are non-right-angled corners, and optionally, each corner of the display panel may be a right-angled corner, which is not described herein again.
In an embodiment, fig. 3 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 3, the display area AA has a corner G including a non-right-angled corner GF, the first touch electrode 10C1 includes a corner touch electrode 10C1G and a non-corner touch electrode 10C1F, and the corner touch electrode 10C1G is adjacent to the non-right-angled corner G; the touch electrode 10C further includes a second touch electrode 10C2, the second touch electrode 10C2 does not overlap the non-display area BA, and the area of the second touch electrode 10C2 is the same as the area of the non-corner touch electrode 10C 1F.
In some display panels with non-right-angled corners, there may be a small difference between the area of the touch electrode adjacent to the non-right-angled corner and the area of the touch electrode in other display areas, and this difference does not affect the touch performance of the display panel, and if the non-display area is disposed in the area where the touch electrode adjacent to the non-right-angled corner is located, a conventional means of a person skilled in the art is to dig out the touch electrode corresponding to the non-display area, and at this time, the area of the touch electrode adjacent to the non-right-angled corner is reduced more, so that the difference between the areas of the touch electrodes in other display areas becomes larger. In the embodiment of the invention, the first touch electrode includes the corner touch electrode, and the corner touch electrode overlaps at least part of the non-display area, so that the situation that the difference between the area of the corner touch electrode and the area of the touch electrode in other display areas is increased is avoided, and meanwhile, the area of the non-corner touch electrode overlapping the non-display area is ensured to be equal to the area of the touch electrode not overlapping the display area in the display area, so that the difference between the area of the first touch electrode overlapping the non-display area and the area of the touch electrode at other positions in the display area can be reduced, and the difference between the touch modulus of each touch electrode in the display panel is reduced.
In an embodiment, fig. 4 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 4, the non-display area BA includes a module-disposed area BAQ, and the first touch electrodes 10C1 at least partially overlap the module-disposed area BAQ in a direction perpendicular to the display panel. The at least partially overlapping condition defined by the invention includes a condition that only partial areas of the first touch electrode and the module setting area are overlapped, and also includes a condition that the first touch electrode and the module setting area are completely overlapped, namely the touch electrode is arranged in the module setting area.

Alternatively, the module setting area may be an optical module setting area, for example, a camera or a sensor may be set in this area. The module setting area is located in the non-display area, the non-display area is an area surrounded by the display area, and is not a frame non-display area surrounding the display area, which is conventionally understood, namely, the display area surrounds the module setting area, namely, the display area is internally provided with the non-display area without a display function, and certain devices can be arranged in the non-display area.
Optionally, in the display panel provided by the present invention, the manufacturing material of the touch electrode layer includes a transparent metal oxide material, for example, an indium tin oxide material, the indium tin oxide material has little influence on the light transmittance in a thin film state, and when the first touch electrode is arranged to overlap with the module setting region, the first touch electrode overlapping with the module setting region does not affect the optical performance of the device arranged in the module setting region.
In an embodiment, fig. 5 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 5, the non-display area BA further includes a wiring area BAZ surrounding the module setting area BAQ, and the display area AA surrounds the wiring area BAZ; the display panel includes a plurality of touch signal lines CX, one touch electrode 10C is electrically connected to at least one touch signal line CX, fig. 5 schematically shows a case where one touch electrode 10C is electrically connected to one touch signal line CX, and optionally, one touch electrode 10C may be electrically connected to two or more touch signal lines CX; the touch signal line CX includes a first touch signal line CX1, the first touch signal line CX1 is electrically connected to the first touch electrode 10C1, at least a portion of the first touch signal line CX1 includes a first routing line CX1R and a first line segment CX1D, which are electrically connected to each other, the first routing line CX1R is located in the routing area BAZ, and the two first line segments CX1D are respectively located at two sides of the non-display area BA.
In order to clearly illustrate the technical features of the embodiment of the present invention, fig. 5 only shows the first touch signal lines electrically connected to the first touch electrodes in a simplified manner, and the touch signal lines electrically connected to other touch electrodes in the display panel are not shown. As shown in fig. 5, a part of the first touch signal lines need not be disposed in the routing area and the first routing lines need to be disposed in the routing area, so as to electrically connect the two first segments located at two sides of the non-display area. Optionally, in order to ensure that the impedance difference between the touch signal lines in the display panel is small, the touch signal lines electrically connected to the touch electrodes that are not overlapped with the non-display area may also have a winding in the routing area, which is not shown in the figure.
The first touch control signal line comprises a first winding and a first line segment which are mutually connected, and the two first line segments are respectively positioned at two sides of the non-display area. In addition, the touch signal line is usually made of a metal material, and the first winding is arranged in the wiring area in the embodiment, so that the metal wiring in the module setting area is avoided, the influence on the performance of the device when the metal wiring is arranged in the module setting area is avoided, and especially, the influence on the optical performance of the optical device can be avoided when the optical device is arranged in the module setting area.

It can be seen from the figure that the module setting area BAQ is located in the non-display area BA, and the non-display area BA is an area surrounded by the display area BA, that is, no sub-pixel is arranged in the non-display area BA and has no display function. Devices such as a camera or a photosensitive device can be provided in the module setting area BAQ. Generally, the area of the module setting area BAQ is smaller than the area of the non-display area BA, and a trace or other circuit components (not shown in the figure) may be disposed in a portion of the non-display area BA surrounding the module setting area BAQ.
