Abstract
A wide field of view (FOV) is required to improve the user experience in mobile applications of light-field displays (LFDs). However, the FOV of liquid-crystal-display-based LFDs is narrow owing to the thick gap between the light-direction-control element and the pixel plane. The thin-encapsulated self-emissive displays, such as organic light-emitting diodes (OLEDs), are beneficial for widening the FOV without losing spatial resolution. With OLEDs, a 72-degree FOV, 12-view, 166-ppi LFD with smooth motion parallax is demonstrated. A moiré-free parallax barrier of arctan (1/4) slant angle is used to reconcile the triangular sub-pixel pattern of OLEDs, and further doubles the spatial resolution by aligning sub-pixels into a single column, instead of the conventional two columns. The effects of crosstalk due to the wide slits on the three-dimensional image quality are analyzed.
