Embodiment Construction

[0021] Referring to FIG. 2A , a 3-D image display according to a first preferred embodiment of the present invention includes a backlight 20 , a display device 25 , and a liquid crystal shutter array 30 .

[0022] The liquid crystal shutter array 30 selectively energizes the areas where the openings 32 and the masks 34 are alternately arranged and switched periodically. The display device 25 is, for example, a transmissive LCD panel.

[0023] The process of forming a left-eye image and a right-eye image by the switching operation of the liquid crystal shutter array 30 is shown in FIGS. 2A and 2B . The display device 25 has left-eye image information and right-eye image information. In addition, each of the left-eye image information and the right-eye image information includes image information according to a plurality of viewpoints. For example, left-eye image information and right-eye image information may include two pieces of image information having different viewpoints...

Abstract

A 3-D image display comprising a backlight, a liquid crystal shutter array having an opening and a mask alternately formed therein and selectively passing light emitted from the backlight by switching the opening and the mask. A display device having left eye image information and right eye image information at a plurality of viewpoints, in which the left eye image information and the right eye image information are changed along the movement of the opening. An image according to the left eye image information and the right eye image information of a plurality of viewpoints is sequentially displayed through the opening.

Description

[0001] This application claims priority from Korean Patent Application No. 2003-52460 filed on Jul. 29, 2003 in the Korean Intellectual Property Office, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a 3-D (three-dimensional) image display, and more particularly, to a 3-D image display that improves resolution by sequentially moving images of a plurality of viewpoints and selectively displaying the images. Background technique [0003] Generally, 3-D images are generated by human eyes based on the principle of stereoscopic vision. Binocular parallax caused by eyes separated by about 65mm from each other can be considered as the most important factor in producing the 3-D effect. Among the 3-D image displays, there are those using glass and those not using glass. Glass-free displays achieve 3-D images by separating the left and right images without using gla...
