A Low Grayscale Uniformity Improvement Scheme for OLED Based on Auto Demura

Late-News

Description:

The semiconductor display industry is accelerating its development, with Demura technology mainly applied to OLED Mini/Micro LED, New display devices such as printing display improve image quality through technical adjustments, making the display effect more uniform and clear. The visual effect of OLED can be characterized by objective indicators such as chromaticity uniformity and luminance uniformity, and requires a lot of manual subjective confirmation to ensure the final compensation effect. In order to reduce human resource costs and automate the Demura algorithm, this paper adopts a U-shaped network model of encoder decoder to objectify the visual features of mura and recognize and classify mura. Different compensation values are used to improve the first pass rate of Demura process for display panels.
