Fig. 1 be a kind of schematic top plan view of display panel provided in an embodiment of the present invention, Fig. 2 be Fig. 1 in along AA ' directions
Schematic cross-section, as depicted in figs. 1 and 2, in multiple pixel electrodes 1 of array distribution；In multiple common electricals of array distribution
Pole 2, multiple public electrodes 2 include multiple electrodes group 3, and each electrode group 3 includes first electrode 31 and second electrode 32；Multiple pressures
Force detection sensor 4, press detection sensor 4 include first input end 41, the second input terminal 42, the first output terminal 43 and second
Output terminal 44,41 and second input terminal 42 of first input end are used to input the first electric signal to press detection sensor 4, and first is defeated
Outlet 43 and second output terminal 44 are for exporting the second electric signal obtained by the first electric signal, in each press detection sensor
In 4 corresponding electrode groups 3, the first output terminal 43 is coupled with first electrode 31, and second output terminal 44 is coupled with second electrode 32, the
One input terminal 41 is electrically connected with the first detection terminal 61, and the second input terminal 42 is electrically connected with the second detection terminal 62.
Specifically, as shown in Figure 1, display panel includes multiple pixel electrodes 1 and multiple public electrodes 2, in detection pressure
When whether detection sensor 4 short circuit or open circuit occurs, wherein pixel electrode 1 is electrically connected a fixed current potential, each public electrode 2
Multiple pixel electrodes 1 can be covered, the pixel electrode 1 that a public electrode 2 can be covered with it forms electric field, each pressure inspection
Survey sensor 4 respectively correspond to an electrode group 3, the first output terminal 43 of press detection sensor 4 in corresponding electrode group 3
First electrode 31 couples, the second output terminal 44 of the press detection sensor 4 and 32 coupling of second electrode in corresponding electrode group 3
It connects, when being detected, the first output terminal 43 exports an electric signal to first electrode 31, and second output terminal 44 is to second electrode 32

The pixel electrode 1 that the electric field and second electrode 32 of the corresponding formation of pixel electrode 1 of this first electrode 31 are corresponding is formed
Electric field it is identical so that the rotation angle of the rotation angle of 31 corresponding liquid crystal 5 of first electrode and 32 corresponding liquid crystal 5 of second electrode
Spend it is identical so that 31 corresponding region of first electrode is identical with the bright dark degree in 32 corresponding region of second electrode.It is pressing
When short circuit or open circuit occur for force detection sensor 4, the electric signal of the first output terminal 43 and the output of second output terminal 44 differs, because
The pixel electrode 1 that the electric field and second electrode 32 of the corresponding formation of pixel electrode 1 of this first electrode 31 are corresponding is formed
Electric field differ so that the rotation of the rotation angle of 31 corresponding liquid crystal 5 of first electrode and 32 corresponding liquid crystal 5 of second electrode
Angle differs, so that the bright dark degree in 32 corresponding region of 31 corresponding region of first electrode and second electrode not phase
Together.
It, can be by comparing 32 corresponding area of 31 corresponding region of first electrode and second electrode after using above-mentioned design
Whether the bright dark degree in domain is identical to judge whether corresponding press detection sensor 4 occurs short circuit or open circuit, also, the first inspection
The first electric signal, and each pressure can be inputted to multiple press detection sensors 4 simultaneously by surveying 61 and second detection terminal 62 of terminal
Force detection sensor 4 corresponds to different first electrodes 31 and second electrode 32, therefore can be by inputting first electric signal
Each pressure detecting sensing can be judged by the bright dark degree of 32 corresponding region of corresponding first electrode 31 and second electrode
Whether device 4 occurs short circuit and open circuit, so as to improve the detection efficiency of display panel, reduces detection duration and improves aobvious
Show the production efficiency of panel, also, due to when being detected, being manually operated without user, it is only necessary to observe first electrode 31
With the bright dark degree of second electrode 32 it may determine that going out whether corresponding press detection sensor 4 occurs short circuit or open circuit, because
This reduces the operation complexity of cost of labor and detection.
