The LEAD's Demura System is an integrated Mura compensation solution designed for OLED module. The design team studied various AMOLED products, optimized the mechanical structure, optical system and control system, matched the most advanced detection algorithm, and accurately extracted sub-pixel luminance (within 2% of the accuracy). The optimized image preprocessing procedure solves the problems of dust and moire pattern, so as to better adapt the Demura-IP compensation characteristics of various IC chips and the best compensation effect. The system can be developed for OLED modules with different SPR layout, size and PPI, especially for various notch shapes and also flexible OLED. It also can quickly change module models ,correspond new products, cycle time customize mass production process, and meet the needs of high-efficiency CT.
