Description:

In the design of VR products based on mini LED backlight (BLU), special attention is paid to reducing halo, improving brightness, and enhancing contrast. This article aims to optimize the PSF curve narrowing and brightness improvement of a small VR mini LED BLU. This scheme is helpful for subsequent local dimming and image contrast improvement.
