[Paper] An Autostereoscopic Display with Time-Multiplexed Directional Backlight Using an Electroluminescent Display as a Light Source

Abstract

In this paper, we propose an autostereoscopic display with time-multiplexed directional backlight using an electroluminescent display as a light source to improve power efficiency and luminance uniformity. We made a prototype system composed of a 26.5-inch OLED display with a refresh rate of 120 Hz for backlight, a 24-inch TN LCD panel with the same refresh rate for imaging, and an interleaved linear Fresnel lens array to generate collimated directional light. We evaluate crosstalk level, ratio of luminance to power consumption, and luminance uniformity given by the conventional system using a pair of LCD panels and the proposed system composed of an LCD panel and an OLED display. It is confirmed that our proposed method improves power efficiency and luminance uniformity.
