Abstract
Embodiments of the present disclosure relate to a pixel circuit, comprising: a liquid crystal capacitor; a selection unit having a first input terminal for receiving a row control signal and a second input terminal for receiving a column control signal, and configured to generate a selection signal indicating whether to select the liquid crystal capacitor according to the row control signal and the column control signal and output the selection signal via an output terminal of the selection unit; and a grayscale voltage writing unit having a first input terminal connected to the output terminal of the selection unit, a second input terminal for receiving a grayscale voltage, a first output terminal connected to a first terminal of the liquid crystal capacitor, and a second output terminal connected to a first voltage, and configured to write a corresponding grayscale voltage of multiple grayscale voltages into the liquid crystal capacitor when the selection signal indicates that the liquid crystal capacitor is selected.
