Joint SKL, SID and ECE Seminar - Effectively allocating the information in a light-field display from a high-throughput field sequential color LCD

The light-field display promises to deliver realistic 3D content but is encountering issues with resolution, field of view, and depth of field, which are essentially caused by insufficient input information or ineffective information allocation in 3D space. To advance light-field displays, we first utilize field-sequential color (FSC) LCDs, which increase information throughput by eliminating color filters and subpixels. We correspondingly propose a series of AI-assisted driving algorithms to alleviate the color breakup issue intrinsically induced by FSC. Next, the optical system must effectively allocate the input digital information. To this end, we leverage the unique multi-aperture architecture of light field displays. For example, synthetic apertures enable super-resolution and wavefront coding to unlock more information in the xy- and z-axes, respectively. An aberration-free telecentric scheme and local phase modulation via vectorial rays retrieve distorted information over a wide xy-range (FoV) and for eyes with refractive errors.
