Abstract:
1. A source driver for a display device comprising: a buffer for buffering an analog voltage corresponding to digital image data; and a switching circuit, connected between an output terminal of the buffer and a data line, for supplying an output voltage from the buffer to the data line multiple times during a horizontal scanning interval of the display device in response to a control signal, wherein the supplying of the output voltage from the buffer to the data line multiple times includes: a first activation interval in which a parasitic capacitor of the data line is charged with the output voltage; a second activation interval, occurring after the first activation interval, in which a pixel capacitor of the data line is charged with the output voltage; and a deactivation interval, between the first activation interval and the second activation interval, in which charge sharing occurs between the parasitic capacitor and the pixel capacitor.
