15‐1: A Novel Compression Algorithm Application for De‐Mura Compensation of AMOLED Panel

Abstract

A novel compression algorithm was adopted to compress De‐mura compensation data, and the compression process was described in detail. The compensation performance of 2x2 compression case is close to the original 2x2 case, and performs better than 4x4 compensation case with the same file size as it. Apart from that, the combination of De‐mura and compression also performs the good compensation results at low gray as well as low display brightness. The better performance, small space occupancy and low power consumption were reached simultaneously, indicating the effective application of combination of compression algorithm and De‐mura algorithm.

69‐2: A Novel Ultra Large Size OLED Display Base on Small‐size OLEDs

“…M ura is inevitable in the production process of OLED, so optical compensation is necessary [5]. The ultra large size OLED in this article is composed of multiple OLED display units, and all OLED display unit have undergone Gamma and Demura algorithm to achieve brightness and color uniformity in a single module.…”
