3-D HLCD SYSTEM AND METHOD OF MAKING

摘要

The invention is directed to an autostereoscopic three-dimensional liquid crystal display system and a method of making the system. The system comprises a collimated backlight (12), a first light diffracting hologram (16), a second right-left interlacing hologram (18) and a liquid crystal display. If the backlight is not collimated, a micro-collimator array (14) is used to collimate the backlight prior to passing into the first hologram. The second right-left interlacing hologram is formed through a two step process. The process comprises positioning a photolithographic mask (44) and a view region mask (52) in a first position, recording the first holographic recording in the first position, shifting the photolithographic mask (44) and the view region mask (52) to a second position and recording the second holographic recording in the second position.
