Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of, and not restrictive on, the embodiments of the invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a schematic structural diagram of an array substrate according to an embodiment of the present invention, and referring to fig. 1, the array substrate includes: the touch control system comprises a plurality of touch control electrode groups 11, wherein the touch control electrode groups 11 comprise at least one touch control electrode 12, the plurality of touch control electrode groups 11 are arranged along a first direction, and the touch control electrodes 12 in the touch control electrode groups 11 are arranged along a second direction; a plurality of touch leads 13, each touch electrode 12 being electrically connected to at least one touch lead 13; at least one compensation signal line 14 is arranged in a gap area between any two adjacent touch electrode groups 11, wherein the compensation signal lines 14 are arranged along a first direction, and each compensation signal line 14 extends along a second direction; the touch electrode 12 is reused as a common electrode in the display stage; the compensation signal line 14 has a common voltage signal input thereto or has the same potential as the touch lead 13. It should be noted that the first direction and the second direction are both parallel to the surface of the array substrate, and the first direction and the second direction are not parallel to each other. In fig. 1, each touch electrode 12 is exemplarily configured to be electrically connected to one touch lead 13, in other embodiments, each touch electrode 12 may also be configured to be electrically connected to a plurality of touch leads 13, and by adopting a manner that each touch electrode 12 is electrically connected to a plurality of touch leads 13, when one touch lead 13 of a certain touch electrode 12 cannot normally work (for example, one touch lead is disconnected), other touch leads 13 can still provide signals for the touch electrode 12.
In the array substrate shown in fig. 1, in the display stage, the touch electrode 12 is multiplexed as a common electrode, and the compensation signal line 14 inputs a common voltage signal or has the same potential as the touch lead 13. When the compensation signal line 14 inputs a common voltage signal, the touch electrode 12 is reused as a common electrode, so that the potential of the compensation signal line 14 is the same as the potential of the touch electrode 12, and the potential of the gap region between each two adjacent touch electrode groups 11 is the same as the potential of the two adjacent touch electrode groups 11, thereby reducing the phenomenon that the liquid crystal deflection on the gap region is influenced due to the absence of the potential of the gap region.
In the display stage, when the compensation signal line 14 and the touch lead 13 have the same potential, since the touch lead 13 inputs the common voltage signal to the touch electrode 12 in the display stage, the compensation signal line 14 and the adjacent touch electrode group 11 have the same potential, and therefore, the deflection of the liquid crystal on the gap region due to the absence of the potential of the gap region can be reduced.
In the touch stage, the touch lead 13 inputs a touch signal to the touch electrode 12, when the compensation signal line 14 and the touch lead 13 have the same potential, the potential of the gap region between the adjacent touch electrode groups 11 is the same as the potential of the adjacent touch electrode groups 11, and the absence of the potential of the gap region between the adjacent touch electrode groups 11 is compensated, so that the influence on the liquid crystal deflection on the gap region is reduced.
In the touch phase, when the compensation signal line 14 has the same potential as the common voltage signal, the potential of the gap region between the adjacent touch electrode groups 11 is the same as the potential of the common voltage signal, and since the difference between the potential of the touch electrode signal and the potential of the common electrode signal is usually small, the potential loss of the gap region can also be compensated.
Fig. 2 is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 2, the difference from fig. 1 is that only one touch electrode 12 is provided in each touch electrode group 11, a plurality of touch sensing electrodes (not shown in fig. 2) may be provided corresponding to the touch electrode 12, and overlapping portions of the touch sensing electrodes and the touch electrode 12 form touch sensing points, where the touch sensing structures are mutually capacitive structures. As can be known from the description of the array substrate in fig. 1, in the display stage and the touch stage of the array substrate in fig. 2, the compensation signal line 14 inputs a common voltage signal or has the same potential as the touch lead 13, so that the potentials of the gap regions of the two adjacent touch electrodes 12 can be compensated, thereby reducing the influence on the liquid crystal deflection on the gap regions due to the absence of the potentials of the gap regions.
In the array substrate provided by the embodiment of the invention, at least one compensation signal line is arranged in the gap area of any two adjacent touch electrode groups, wherein each compensation signal line is arranged along the first direction, each compensation signal line extends along the second direction, the touch electrodes are reused as the common electrodes in the display stage, and the compensation signal lines are enabled to input common voltage signals or have the same potential as the touch leads, so that the potentials of the gap areas of the two adjacent touch electrode groups in the display stage and the touch stage can be compensated, and the influence on the liquid crystal deflection on the gap areas caused by the absence of the potential of the gap areas is reduced.
Fig. 3 is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 3, a compensation signal line 14 (only one compensation signal line 14 is schematically shown between two adjacent touch electrode groups 11 in fig. 3) is electrically connected to an adjacent touch lead 13, and by electrically connecting the compensation signal line 14 to the adjacent touch lead 13, the length of a connection lead between the touch lead 13 and the compensation signal line 14 and the complexity of a connection route are reduced, the space utilization rate of the array substrate is improved, the difficulty of a processing process is reduced, and the yield is indirectly improved. In addition, if the compensation signal line 14 is connected to the touch electrode 12, a via process is usually required to electrically connect the compensation signal line 14 and the touch electrode 12, when a via is formed, the etching process may cause a certain damage to the touch electrode, and the connection of the compensation signal line 14 to the touch lead 13 may prevent the damage to the touch electrode 12.
Fig. 4 is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 4, the array substrate includes a non-display area, and electrical connection points of the compensation signal lines 14 and the touch leads 13 are located in the non-display area. By electrically connecting the compensation signal line 14 and the touch lead 13 in the non-display area, the electric connection position of the compensation signal line 14 and the touch lead 13 can be prevented from occupying the space of the display area, and the aperture ratio of the display area is prevented from being reduced. In addition, since the gap between the touch electrodes 12 in the display area is usually small, if the compensation signal line 14 is disposed in the display area and electrically connected to the touch lead 13, the structure of the display area is too complex, and therefore, the electrical connection point between the compensation signal line 14 and the touch lead 13 is located in the non-display area, which can reduce the process complexity of the display area. The compensation signal line 14 is electrically connected to the adjacent touch lead 13, the compensation signal line 14 may be electrically connected to the left touch lead 13 as shown in fig. 3, or the compensation signal line 14 may be electrically connected to the right touch lead 13 as shown in fig. 4.
Fig. 5 is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 5, the array substrate includes a first driving chip 15, the compensation signal line 14 is electrically connected to the first driving chip 15, and the first driving chip 15 provides a common voltage signal for the compensation signal line 14. The array substrate shown in fig. 5 uses the first driving chip 15 to provide the common voltage signal for the compensation signal line 14 to compensate for the potential loss in the gap region between two adjacent touch electrode sets 11, and provides another way to provide the common voltage signal for the compensation signal line 14.
Fig. 6A is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 6A, the array substrate includes a second driving chip 16, and the second driving chip 16 is electrically connected to both ends of the touch lead 13 to provide signals for the touch lead 13. As can be seen from fig. 6A, the second driving chip 16 can be accessed from the upper and lower sides of the touch electrode 12 to provide signals for the touch lead 13, the second driving chip 16 includes a signal output port 161 and a control port 162, and the control port 162 controls whether to allow the signals in the signal output port 161 to be input into the corresponding touch electrode 12. In other embodiments, there are multiple connection manners between the second driving chip 16 and the touch lead 13, referring to fig. 6B, the second driving chip 16 can also be accessed from the upper side of the touch electrode 12 alone to provide signals for the touch lead 13. Referring to fig. 6C, the second driving chip 16 can also be accessed from the lower side of the touch electrode 12 alone to provide signals for the touch lead 13. In the actual design process, what access method is adopted needs to be determined according to the space size of the non-display area of the array substrate, the layout of the touch leads 13 and the like. In addition, when the second driving chip 16 is inserted from the upper side and the lower side of the touch electrode 12, the influence of voltage drop caused by the resistance of the touch lead 13 when the length of the touch lead 13 is long can be reduced.
Fig. 7 is a schematic structural diagram of another array substrate according to an embodiment of the present invention, and referring to fig. 7, the compensation signal lines 14 between any two adjacent touch electrode groups 11 are electrically connected to each other. The compensation signal lines 14 between two adjacent touch electrode groups 11 are electrically connected with each other, so that on one hand, the potentials of the compensation signal lines between two adjacent touch electrode groups 11 are the same, on the other hand, the wiring complexity of the compensation signal lines 14 is simplified, and the signal sources of the compensation signal lines 14 between two touch electrode groups 11 are consistent, and the uniformity of compensation signals is relatively good; in addition, the compensation signal lines 14 between any two adjacent touch electrode groups 11 are electrically connected with each other, so that the number of connection points or interfaces required for the compensation signal lines 14 to be electrically connected with the touch leads 13, the first driving chip 15 and the second driving chip 16 is also reduced.
On the basis of the above embodiments, optionally, the compensation signal line 14 and the touch lead 13 are formed in the same layer. The compensation signal line 14 and the touch lead 13 are formed in the same layer in the processing process, so that the processing steps can be simplified, and the processing time and the processing cost can be reduced.
On the basis of the above embodiment, optionally, each touch lead 13 is electrically connected to the corresponding touch electrode 12 through at least one via hole. Each touch electrode 12 is electrically connected with a touch lead 13, and since the touch lead 13 and the touch electrode 12 are located on different layers, at least one via hole is formed between the touch lead 13 and the touch electrode 12 by using a via hole process, and the touch lead 13 is electrically connected with the corresponding touch electrode 12 by using the via hole. When a plurality of via holes are used for connection, it can be ensured that the touch lead 13 and the touch electrode 12 can still be electrically connected when a certain via hole has a connection defect.
