TOUCH CONTROL DISPLAY

摘要

A touch control display is disclosed, which includes: a planar display, a display drive circuit, a touch control circuit and a display/touch control signal strobe output circuit or a display/touch control signal load circuit. The touch control circuit is provided with a touch control excitation source and a touch control signal detect circuit. A row electrode set and a column electrode set are provided on the substrate of the display screen. The touch control circuit detects whether the electrode has been touched by applying the touch control signal to certain electrode line of the row electrode set or the column electrode set and detecting the change of the touch control signal on the electrode line. The touch control circuit takes a sample for the touch control signal on certain electrode line with a period of the display frame or a period of the integral multiple of the display frame, and takes a data sample for the touch control signal with the fixed synchronization relationship with the touch control signal applied to the electrode line. The fixed synchronization relationship means that each time for achieving the sample data is on the same specific phase point of the touch control excitation source signal waveform.
