How to Ensure a Good Depth Perception on a Light Field Display

In this article, we define the technical requirements for a light field display to provide effective depth cues such as binocular disparity, motion parallax, and accommodation at a pixel resolution expected by the eye. These requirements are evaluated with respect to existing technologies (e.g.,integral imaging displays) or expected future ones (e.g., micro-light-emitting diode (LED) displays). Simulation of light field displays are proposed for different display sizes (smartphone, desktop, or TV), resolution per view, and pixel pitch. These simulations convey the main impact of the pixel pitch to reach the light field display goal in terms of depth cue requirements. The last part of the paper focusses on data generation issues: how to generate the necessary amount of views at the display side and what the adapted data formats are for such a purpose. The paper is associated with supplementary videos that will illustrate the view generation topic using a dedicated data format that is optimized for current graphics processing unit (GPU) processors. Video capture of early-stage light field displays will also be provided
