Array substrate, touch screen and display apparatus containing the same, and method for driving the same
Abstract:
The present disclosure provides a method for driving an array substrate for fingerprint recognition. The method includes sequentially sending a switch-on signal by a processing unit to each gate line row by row along the column direction, the switch-on signal being divided into a first phase and a second phase. In the first phase of each switch-on signal, sending a touch-driving signal to pixel electrodes corresponding to the gate line through a first data line in each data line group, receiving a touch-sensing signal through a second data line in each data line group, and constructing a fingerprint pattern based on touch-sensing signals. In the second phase of each switch-on signal, simultaneously sending display signals to the first data line and the second data line in the data line groups to charge subpixel units corresponding to the gate line for displaying an image.
