TOUCH CONTROL AND DISPLAY CIRCUIT AND TOUCH CONTROL AND DISPLAY METHOD OF TOUCH SCREEN, AND METHOD FOR CONTROLLING TOUCH SCREEN

摘要

A touch control and display control module of a touch screen includes (n×y) rows of sensing units disposed on a substrate. The touch control and display control module includes: a control circuit, controlling the touch screen to operate in one of a frame update mode and a touch sensing mode; and n first control lines, y second control lines and n control signal output circuits disposed on the substrate. Each control signal output circuit is coupled to one of the n first control line, and includes y control signal buffer units. Each control signal buffer units is coupled to one of the y second control lines and sensing units of one row to output a voltage signal to the sensing units of that row, to cause the sensing units of that row to operate in one of the frame update mode and the touch sensing mode.
