摘要
A touch control display able to remove touch control impact on display is disclosed, which includes: an active liquid crystal display screen, a display driving circuit, a touch control circuit and a display/touch control signal strobe output circuit or a display/touch control signal load circuit. One substrate of the display screen is provided with a row and column electrode set, and another substrate of the display screen is provided with a common electrode. There is a frame blanking time period between each two display scanning time periods of the electrode of the display screen. In this time period, the display screen does not execute the display driving, the scan to the row electrode is stopped, the column electrode and COM electrode maintain in original outputting state or certain preset outputting signal, and some or all of the active elements in the display screen are on cut-off state. In the period of transmitting the touch control signal by the display screen electrode, the instantaneous potential difference of the applied touch control signal between each electrode enables the active elements to keep in the cut-off state, and removes the touch control signal impact on display.
