Benefits of technology

The present invention is a liquid crystal display that can switch between 2D and 3D images to improve the viewing angle and reduce image crosstalk. The display uses a liquid crystal barrier layer to create a better experience for the viewer.

Problems solved by technology

Conventionally, when the viewer squarely observes the three-dimensional image on the LCD, the vertical viewing angle is decreased, which results from the image crosstalk.
In other words, one eye of the viewer observes the image signal originally projected to the other eye of the viewer so that the image signal of the right eye is interfered with the other image signal of the left eye, which results in a narrowed visual field angle.

Abstract

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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an image display apparatus, and more particularly to two-dimensional and three-dimensional (2D / 3D) image switching type liquid crystal display.BACKGROUND OF THE INVENTION[0002]The three-dimensional image display applies stereoscopic or autostereoscopic technique to display three-dimensional images. The stereoscopic technique implements the three-dimensional effect by the image parallax of the viewer's right and left eyes. The stereoscopic technique includes the methods with the polarized glasses and without the polarized glasses, which are widely employed. In the manner of taking polarized glasses, the image parallax of the viewer's right and left eyes can be displayed on the display apparatus based on direct sense of sight by changing the polarization direction of the image parallax of the viewer's right and left eyes. For example, a film-type patterned retarder (FPR) is applied to liquid crystal display (LCD) so that the...
