Title:
PIXEL DRIVER CIRCUIT, PIXEL DRIVING METHOD, DISPLAY PANEL, AND, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/118055
Kind Code:
A1
Abstract:
The present invention provides a pixel driver circuit, comprising: a driver transistor (MDT), a first storage capacitor (C1), a second storage capacitor (C2), a threshold compensation unit (11), a data writing unit (12), and a light-emission control unit (13). In a threshold compensation phase, the threshold compensation unit (11) controls to switch on the driver transistor (MDT), thereby discharging electricity to a voltage reset path (Vini) until the driver transistor (MDT) is switched off. In every data writing phase, the data writing unit (12) controls a data voltage (SD) and writes into a gate of the driver transistor. In a light-emission phase, the light-emission control unit (13) controls and switches on the driver transistor (MDT) to drive a light emission of a light-emitting element (LE).The total electric charge of the first storage capacitor (C1) and the total electric charge of the second storage capacitor (C2) are the same during the threshold compensation phase and the data writing phase. An electric charge of the first storage capacitor (C1) during the data writing phase is the same as an electric charge of the first storage capacitor (C1) during a light-emission control phase.
