The embodiment of the invention provides a pressure sensor driving circuit and driving method and a display panel and method. The pressure sensor driving circuit comprises a pressure sensor group, a driving chip and a switching unit corresponding to the pressure sensor group; the pressure sensor group comprises a first pressure sensor and a second pressure sensor; the switching unit is used for switching the first mode and the second mode, the first pressure sensor is connected with the driving chip in the first mode, and the second pressure sensor is connected with the driving chip in the second mode; and by switching the modes, the other pressure sensor in the pressure sensor group is made to be connected with the driving chip to replace the pressure sensor which cannot work normally towork normally, therefore, the number of the normally-working pressure sensors in the pressure sensor driving circuit cannot be decreased, and then the accuracy of a detection result of the pressure sensor driving circuit cannot be reduced.
Description
【Technical field】 [0001] The present invention relates to the field of touch technology, in particular to a pressure-sensitive sensor driving circuit and driving method, a display panel and a device. 【Background technique】 [0002] Display panels with touch functions are widely used in various display devices such as mobile phones, tablet computers, and information inquiry machines in public halls. The user can operate the display device only by touching the mark on the display panel with a finger, which eliminates the user's dependence on other input devices (such as keyboard and mouse) and makes human-computer interaction easier. [0003] In order to better meet the needs of users, a pressure-sensitive sensor driving circuit is usually provided in the touch display panel. The pressure-sensitive sensor driving circuit includes a plurality of pressure-sensitive sensors for detecting the pressure of the user when pressing the touch display panel. The touch display panel can ...
