A Novel Mura Compensation Algorithm for VR Displays

Description:

The compensation of Mura defects is a key concern for enhancing image quality in display manufacturing. The Mura compensation method should be tailored to the specific characteristics of each application, such as automotive, notebook PCs, and virtual reality (VR) systems. VR applications, in particular, require compensation that accounts for additional luminance degradation and position adjustments due to lens shape, with area-power efficiency also being important. In this paper, we propose a Mura compensation algorithm that effectively improves luminance uniformity of VR displays. In addition, a compression method is applied, which reduces memory requirements while minimizing data loss, considering area-power efficiency. Our verification results on a test system with VR displays show that the proposed algorithm can achieve high luminance uniformity in the unique shape of VR displays and reduce implementation complexity with compressed compensation data.
