DIGITAL CAPACITIVE TOUCH CONTROL SCREEN

摘要

A digital capacitive touch control screen (100) comprises a touch control substrate (110) and a touch control circuit (140) which comprises a touch control excitation source and a touch control signal detection circuit. At least two intersecting electrode groups (120,130) are arranged on the touch control substrate (110), each electrode line of which is connected to the touch control actuator. During touch control circuit (140) operation, the touch control excitation source applies, for at least one moment, a touch control signal to more than two electrode lines simultaneously, and the touch control signal detection circuit detects the change of the touch control signal of at least one electrode line thereof. This enables the realization of a large, high resolution digital capacitive touch control screen.
