Abstract
A signal receiver includes a signal receiving line, a signal processing circuit and a compensation circuit. The signal receiving line receives a driving signal through a first capacitor and is coupled to a plurality of display pixel circuits through a second capacitor. The signal processing circuit is coupled to the signal receiving line, receives a received signal on the signal receiving line and generates a touch detection information according to the received signal. The compensation circuit is coupled to the signal receiving line, generates a first compensation current according to driving currents of the display pixel circuits, generates a second compensation current according to sinking currents of the display pixel circuits, and generates a compensation signal according to the first compensation current and the second compensation current.
