Abstract
A display apparatus including a voltage buffer, a display panel and a pixel loading compensation circuit is disclosed. The voltage buffer is used to receive a ramp voltage and output an output current. The display panel includes pixel switches and pixel capacitors. The pixel switches are arranged in parallel and coupled to the voltage buffer. The pixel capacitors are coupled between the pixel switches and ground. The pixel loading compensation circuit includes compensation switches and compensation current sources. The compensation switches corresponding to the pixel switches are arranged in parallel and coupled to the voltage buffer. The compensation current sources are coupled between the compensation switches and ground. The operation of the compensation switches is opposite to the operation of the corresponding pixel switches.
