Frequency Decomposition-Based High-Performance Demura Processing with Low Memory Cost

• Pilseung Heo

Description:

We propose a novel demura method that decomposes the display mura profile into a high spatial frequency component and several low spatial frequency components. By effectively allocating the components during demura processing, we achieved high performance in luminance uniformity. This approach can also implement h/w reduction in memory size, making it more cost-effective in DDIC.
