A Smart Foveal VR Display Algorithm base on SPR Pixel Arrangement and Smart View Driving

VR(Virtual Reality) Display always need high PPI(Pixel Per Inch) and high resolution because of its near eye amplification effect and large viewing angle. It is not uncommon to find a 4K or 8K solution today. With the growth of PPI and resolution, display manufacture technology and data transmission become a much more harder problem. Central foveal technology is usually used in gazing point VR system, there is a lot of good ideas in camera and GPU technology, but it seems rarely have something that display panel can do. In this paper, we present a smart foveal VR display algorithm base on BOE SPR (Sub‐pixel Rendering) pixel arrangement(which is called BV3: BrightView3 by BOE) and smart view driving function. The change of pixel arrangement relieve the pressure of manufacture requirement, and SPR algorithm used to maintain the picture quality. And the change of panel’s driving method help to solve the data transmission problem, we use a smart foveal algorithm to deal with the data of central foveal area and non‐foveal area separately. As a result, the algorithm can help to save 3/4 data transmission band width.
