Title

High Performance Compressive Light Field 3D Displays

Abstract：

Compressive light field 3D display has the advantages of high spatial resolution and large display depth, but it is limited by narrow viewing angle and heavy computation. To address these issues, this presentation introduces our research team's work on improving the viewing angle and reducing the computation of compressive light field 3D display. By introducing foveated rendering into compressive light field near-eye displays, the computation is significantly reduced while providing high-quality focus cues within the fovea. By using deep learning to synthesize encoded images for compressive light field displays, the display quality and uniformity are improved without the need for cumbersome iterations. A weight optimization algorithm for additive light field tracking displays is proposed, which effectively saves display bandwidth to present 3D display content for multiple viewers. Finally, based on the independent visual characteristics of human eyes such as flicker fusion, binocular disparity, and motion parallax, and by fully utilizing the high refresh rate, high spatial resolution, and image content correlation of the display panel, a hybrid naked-eye 3D display combining multi-directional backlighting, integral imaging, and compressive light field is developed to further enhance the viewing angle, display depth, and image quality of 3D display.
