STEREOSCOPIC IMAGE DISPLAY APPARATUS
First Claim
1. A stereoscopic image display apparatus comprising:
- a liquid crystal display which comprises a liquid crystal panel including a plurality of horizontal rows of aligning pixels, the horizontal rows being arranged in vertical direction, and a pair of polarizing plates which sandwich the liquid crystal panel;
a backlight located on a back surface side of the liquid crystal display;
an optical unit located on a front surface side of the liquid crystal display;
polarizing eyeglasses worn by a viewer in viewing images on the liquid crystal display; and
a control apparatus which controls image display on the liquid crystal display, and phase difference states of the optical unit, whereinthe liquid crystal display comprises a first image forming area and a second image forming area, and is controlled by the control apparatus such that the first image forming area displays one of a right eye image and a left eye image and, simultaneously, the second image forming area displays the other image of the right eye image and the left eye image, and the liquid crystal display displays a frame image in which the right eye image and the left eye image are respectively interlaced,the control apparatus controls the first image forming area and the second image forming area so that(1) the right eye image and the left eye image are replaced every time a frame is switched, or(2) the right eye image and the left eye image are replaced when the frame is switched or an image displayed in an immediately previous frame is overwritten,the frames are switched at a rate of at least 120 Hz, andthe optical unit arranges a first polarizing area and a second polarizing area in ranges corresponding to the first image forming area and the second image forming area and the first polarizing area and the second polarizing area have respective different phase difference states, the different phase difference states being controlled by the control apparatus in synchronization with the timing at which the right eye image and the left eye image are replaced.

Abstract
A stereoscopic image display apparatus reduces flicker and crosstalk, and provides a viewing screen of high brightness without decreasing resolution. The stereoscopic image display apparatus includes: a liquid crystal display which has a first image forming area and a second image forming area corresponding to horizontal rows; and an optical unit in which a first polarizing area and a second polarizing area are arranged in correspondence with the first and second image forming areas. A frame image displays a right eye image on the first image forming area and a left eye image on the second image forming area, and alternately replaces or overwrites the image forming areas every time the frame is switched. The optical unit replaces, in synchronization with the timing at which the first and second image forming areas are replaced. The phase difference states are replaced between the first polarizing area and the second polarizing area.
