2D/3D image switching type liquid crystal display

摘要

A 2D/3D image switching type liquid crystal display is described. The 2D/3D image switching type liquid crystal display includes a liquid crystal display (LCD), a film-type patterned retarder (FPR) and a liquid crystal barrier layer. When either the FPR is disposed between the LCD panel and the liquid crystal barrier layer or liquid crystal barrier layer is disposed between the LCD panel and the backlight module, an electrical field controls the first grating regions and the second grating regions to form a bright region and a dark region for adjusting the left-hand circularly polarized light and the right-hand circularly polarized light from the FPR to switch 2D/3D image by switching the liquid crystal barrier layer.

1. A two-dimensional and three-dimensional (2D/3D) image switching type liquid crystal display, comprising:
a liquid crystal display (LCD) panel, for being passed by a light beam along a first direction to form a left-eye image and a right-eye image; a film-type patterned retarder (FPR) disposed on one side of the LCD panel and comprising a plurality of first phase difference regions and a plurality of second phase difference regions mutually interlaced with the first phase difference regions, wherein the left-eye image and the right-eye image correspondingly pass through the first phase difference regions and the second phase difference regions for forming a left-hand circularly polarized light and a right-hand circularly polarized light by the FPR; and a liquid crystal barrier layer comprising a plurality of first grating regions and a plurality of second grating regions mutually interlaced with the first grating regions, the FPR being disposed between the liquid crystal barrier layer and the LCD panel, and the first grating regions and the second grating regions corresponding to the first phase difference regions and the second phase difference regions, wherein an electrical field controls the first grating regions and the second grating regions to form a bright region and a dark region for adjusting the left-hand circularly polarized light and the right-hand circularly polarized light from the FPR so that either a left eye and a right eye of a viewer can simultaneously observe one of the left-eye image and the right-eye image to form a two-dimensional image or the left eye and the right eye can correspondingly observe the left-eye image and the right-eye image respectively via the bright region to form a three-dimensional image by switching the liquid crystal barrier layer.
