PIXEL CIRCUIT, DISPLAY DEVICE, DISPLAY APPARATUS AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/018883
Kind Code:
A1
Abstract:
Disclosed is a pixel circuit, comprising: a liquid crystal capacitor (Clc), a selection unit (110), wherein a first input end of the selection unit (110) is used to receive a row control signal, a second input end is used to receive a column control signal; the selection unit (110) is used to generate, according to the row control signal and the column control signal, a selection signal indicating whether to select a liquid crystal capacitor; and the selection signal is output by an output end of the selection unit (110), and a gray scale voltage write-in unit (120), wherein a first input end of the gray scale voltage write-in unit (120) is connected to the output end of the selection unit (110); a second input end is used to receive a gray scale voltage (Vgray); a first output end is connected to a first end of the liquid crystal capacitor (Clc); and a second output end is connected to a first voltage (V1), which is used to write, to the liquid crystal capacitor (Clc), a corresponding gray scale voltage in a plurality of gray scale voltages when the selection signal indicates the selection of the liquid crystal capacitor (Clc).
