Title:
ORGANIC LIGHT EMITTING PANEL STARTING-UP BRIGHTNESS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/201541
Kind Code:
A1
Abstract:
The invention discloses a starting-up brightness control method for an organic light emitting panel. The method comprises the following steps: acquiring a displaying brightness corresponding to each pixel in a starting-up process; comparing the displaying brightness of each pixel with a preset brightness threshold value; if the displaying brightness is greater than the brightness threshold value, adjusting the displaying brightness to be smaller than or equal to the brightness threshold value; adjusting a displaying grayscale value of the pixel by using the adjusted displaying brightness; using the adjusted displaying grayscale value to control the corresponding pixel to display; and gradually increasing the brightness threshold with time, and returns to obtain the displayed brightness corresponding to each pixel during the starting-up process. In this way, the ghost rate of the panel caused by excessive voltage offset during starting up can be reduced and excessive aging speed of a panel device caused by excessive local current is reduced.
