Abstract:
A touch control display screen includes: a touch control electrode layer including a plurality of touch control electrodes; a first electrode layer opposite to the touch control electrode layer and including a plurality of first electrodes; a liquid crystal layer between the touch control electrode layer and the first electrode layer; a switch control circuit connected with at least one touch control electrode; a display control circuit connected with the first electrodes; and a synchronization control circuit connected with the switch control circuit. In the display stage, the display control circuit outputs a first common voltage, and the synchronization control circuit controls the switch control circuit to output a second common voltage equal to the first common voltage. Many advantages are provided, such as a uniform display effect, fewer residual ions, better display quality, higher reliability, simplified circuit, lower cost, and increased light transmittance.
