Title:
OUTPUT DRIVER OF DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/235731
Kind Code:
A1
Abstract:
An output driver of a display device according to an embodiment of the present application comprises: a digital-to-analog converter which generates a coarse voltage and a fine voltage; a control unit which alternately charges first and second capacitors on the basis of the voltage difference between the coarse voltage and the fine voltage; and an amplifying unit which alternately receives the respective charging voltages charged in the first and second capacitors, and continuously outputs an output voltage. The control unit outputs a second charging voltage charged in the second capacitor to an output node of the amplifying unit during a first charging period for charging a first charging voltage in the first capacitor.
