Title:
OLED DISPLAY METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/062456
Kind Code:
A1
Abstract:
The present invention provides an OLED display method and device. The method comprises: obtaining a resistance value of an N-th row of Data lines; determining the duty cycle of an EM signal of the N-th row of Data lines according to the resistance value of the N-th row of Data lines, a preset resistance value, and the duty cycle of a preset light-emitting EM signal; and finally, outputting a control signal to the N-th row of Data lines according to the duty cycle of the EM signal of the N-th row of Data lines. The duty cycle of the EM signal of each row of Data lines is determined based on the preset resistance value, the duty cycle of the preset EM signal, and the resistance value of each row of Data lines, so that each row has corresponding duty cycle of the EM signal. When the EM signals of each row of Data lines are used to control the signals of each row respectively, the luminance of the OLEDs corresponding to each row of Data lines tends to be consistent, and the luminance uniformity of the OLED products is effectively improved.
