TOUCH-CONTROL FLAT PANEL DISPLAY

摘要

A touch-control flat panel display, includes a display screen, a display driving circuit, and a touch-control detecting circuit. The correlated circuits within the touch-control flat panel display enables the display screen to be used not only for transmitting display driving signals but also for transmitting touch-control signals, enables the display driving and the touch-control detecting to multiplex a display screen electrode, and enables the touch-control flat panel display to be used not only for normally displaying but also for realizing the touch-control detecting. By simultaneously loading touch-control signals on a detecting electrode and a non-detecting electrode, the touch-control flat panel display can reduce the flow of the touch-control signals between the detecting electrodes and between the detecting electrode and non-detecting electrodes, control the flow direction of the touch-control signals, and improve the accuracy of judgment for a touched electrode. By simultaneously loading touch-control signals on multiple sets of the detecting electrodes, and by separately detecting changes of the touch-control signals which flow through each set of the detecting electrode, the touch-control flat panel display shortens the time for detecting touch point on the whole display screen.
