Touch display device, touch-driving circuit, and touch-sensing method
Abstract:
A touch display device, a touch driving circuit, and a touch-sensing method are disclosed in which control operation timing at which a charge control circuit connected to an input terminal of a pre-amplifier is controlled in consideration of a difference in a location or time constant for each touch electrode. Accordingly, unnecessary variation in a signal-to-noise ratio for each touch electrode can be reduced, and thus touch sensitivity can be improved.
