Title:
PIXEL DRIVING CIRCUIT WITH WIDE RANGE INPUT VOLTAGE
Document Type and Number:
WIPO Patent Application WO/2019/136898
Kind Code:
A1
Abstract:
A pixel driving circuit for a sub-pixel in light-emitting display is disclosed. The pixel driving circuit includes a driving sub-circuit (21) comprising N driving transistors connected in series. N is an integer greater than 1. The N driving transistors include a first driving transistor having a source electrode coupled to a first input voltage port and an N-th driving transistor having a drain electrode coupled to a light-emitting diode. Additionally, the pixel driving circuit includes a power-storage sub-circuit (22) coupled to a gate electrode of the first driving transistor and the drain electrode of the N-th driving transistor. Furthermore, the pixel driving circuit includes a charge-input sub-circuit (23) configured to use a first control signal from a first scan line to control a connection between the gate electrode of the first driving transistor and a data line supplying a data voltage.
