Wide field-of-view light-field displays based on thin-encapsulated self-emissive displays

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 moire-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.

Automated summary

Using thin-encapsulated self-emissive displays like OLEDs can widen the FOV and improve the user experience in LFD mobile applications. By aligning sub-pixels into a single column and using a moire-free parallax barrier, the spatial resolution and motion parallax of LFD can be enhanced significantly. The crosstalk effects caused by wide slits on the 3D image quality are also analyzed in the study.
