Light-Field Displays: a View-Dependent Approach

Most 3D displays suffer from the vergence-accommodation conflict, which is a significant contributor to eyestrain. Light-field displays avoid this conflict by directly supporting accommodation but they are viewed as requiring too much resolution to be practical, due to the tradeoff between spatial and angular resolution. We demo three light-field display prototypes that show a view-dependent approach which sacrifices viewer independence to achieve acceptable performance with reasonable display resolutions. When combined with a directional backlight and eye tracking system, this approach can provide a 3D volume from which a viewer can see 3D objects with accommodation, without wearing special glasses.
