Abstract

A multilayer liquid crystal display (LCD) is a display device constructed by stacking multiple liquid crystal layers on top of a light source. As shown in a previous study, a multilayer LCD can deliver varying images depending on the viewers'eye positions, and can be used for auto-stereoscopic 3D viewing. However, undesirable blurring is sometimes observed in the images that a viewer receives from the display. Such blurring is notable especially around objects in the scene that are far away from the viewer. To address this problem, we propose to put a convex lens in front of the layers of liquid crystal. The lens refracts the beams of light, thus bringing the effects of moving the objects to nearer positions. Through a simulation-based study, we show that an optimal choice exists for the focal length of the lens, which reduces the local image blurring while not compromising the overall image quality.
