Abstract

The invention discloses a touch panel, a driving method thereof and a display device, and belongs to the technical field of touch display. The touch panel comprises a plurality of recognition units and a plurality of touch units; one touch unit is multiplexed into a plurality of identification units; one touch unit row comprises a plurality of identification unit rows, and one touch unit column comprises a plurality of identification unit columns; the first control circuit is electrically connected with the identification unit; the touch panel at least comprises a touch stage and an identification stage; in the touch control stage, the first control circuit provides touch control driving signals for the multiple recognition unit rows of one touch control unit row at the same time; in the recognition stage, the first control circuit sequentially provides recognition driving signals for the multiple recognition unit rows of one touch unit row. The driving method is applied to the touch panel for driving work. The display device comprises the touch panel. The touch mode and the recognition mode can be freely switched, the power consumption can be reduced, and the response time during touch is shortened.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a touch panel, a driving method thereof, and a display device. Background technique [0002] A touch screen is a simple and easy-to-use input device configured to recognize a touch position or related information generated by a user on a screen by touching or pressing with a finger or the like, and transmit the touch position or related information of the screen to a system. Capacitive touch screens have high transmittance, excellent durability, high touch resolution and multi-touch capability. Touch screen panels are applied not only to mobile devices (eg, smartphones, tablet personal computers, etc.) but also to various electronic devices (eg, automatic teller machines (ATMs), automatic ticket vending machines, navigation devices, etc.). In recent years, more and more electronic devices use fingerprint recognition devices to identify users. Because the ...
