DISPLAY DRIVING CIRCUIT, DISPLAY APPARATUS AND DRIVING METHOD THEREFOR

摘要

A display driving circuit, a display apparatus and a driving method therefor can avoid influence of a feed through effect on a potential difference between a pixel electrode and a public electrode and improve display quality of an image. The display driving circuit comprises: a grid electrode driving unit (21) used for controlling opening of a thin film transistor (TFT), a source electrode driving unit (22) used for outputting a signal to a source electrode of the TFT, and a circuit unit (23) used for supplying power to the public electrode. When the TFT is in an open state, the circuit unit (23) outputs a first voltage to the public electrode. When the TFT is in a closed state, the circuit unit (23) outputs a second voltage to the public electrode. The first voltage and the second voltage are different voltages.
