Title:
METHOD FOR DRIVING PIXEL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/006820
Kind Code:
A1
Abstract:
A method for driving a pixel circuit, comprising: obtaining actual threshold voltage (Vth) and actual current-voltage conversion coefficient (k) of a drive thin film transistor (T22), and actual light emitting efficiency (η) of an organic light emitting diode (OLED) in sequence (S110); and calculating a compensation data signal input to a source electrode of a switch thin film transistor (T21) according to the obtained actual threshold voltage (Vth) and actual current-voltage conversion coefficient (k) of the drive thin film transistor (T22), and the actual light emitting efficiency (η) of the organic light emitting diode (OLED) (S120).
