Title:
PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREOF, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2018/149167
Kind Code:
A1
Abstract:
Provided are a pixel driving circuit and a driving method thereof, and a display panel. The pixel driving circuit comprises: a data write circuit (1); a reset circuit (2); a storage circuit (3); a compensation control circuit (4); a light emission control circuit (5); a drive transistor (M0); and multiple light-emitting devices (L_1, L_2, L_3). In the pixel driving circuit, data signals at a data signal terminal (Data) can be inputted at different times by means of the data write circuit (1), and the respective light-emitting devices (L_1, L_2, L_3) and a second electrode (m2) of the drive transistor can be electrically connected at different times by means of the light emission control circuit (5), such that the multiple light-emitting devices (L_1, L_2, L_3) can be controlled to emit light at different times, thereby simplifying a structure of the pixel driving circuit, reducing a space for accommodating the pixel driving circuit, increasing a pixel aperture ratio, and increasing PPI of a display panel.
