Patent ID: 10424261

Abstract:
A pixel circuit and driving method thereof and display apparatus are disclosed. The pixel circuit comprises: a selection circuit (P1), whose input terminal is connected to a selection signal terminal, a high level signal terminal and a low level signal terminal, configured to control charging or discharging of a pixel capacitor according to a digital signal input by the selection signal terminal; a charging/discharging circuit (P2), whose input terminal is connected to an output terminal of the selection circuit and a same row gate line signal terminal corresponding to the pixel capacitor and output terminal is connected to the pixel capacitor, configured to charge or discharge the pixel capacitor under the control of the selection circuit; and a pre-charging circuit (P3), whose input terminal is connected to a previous row gate line signal terminal corresponding to the pixel capacitor and output terminal is connected to the pixel capacitor, configured to provide a reference voltage. This pixel circuit saves the digital-analogy conversion circuit and the analogy circuit part in the driving IC.
