Abstract
A stereoscopic image display apparatus for displaying a three dimensional image on a screen of a display panel comprises a three dimensional video signal processor for converting an analog three dimensional video signal to a digital three dimensional video signal, and a micropolarizer attached to the display panel. The micropolarizer is composed of a plurality of first polarizing regions having a first polarizing direction and a plurality of second polarizing regions having a second polarizing direction perpendicular to the first polarizing direction. The first and second polarizing regions are alternately arranged with each other in the form of a matrix. The three dimensional video signal processor further includes a video/sync signal separator for separating the analog three dimensional video signal into an analog video signal and a synchronizing signal, a clock signal generator for generating a clock signal with a frequency corresponding to the synchronizing signal, a control signal generator for generating various control signals in response to the clock signal, an A/D converter for converting the analog video signal to a digital video signal, a first memory device for storing the part of the digital video signal belonging to the odd field, a second memory device for storing the part of the digital video signal belong to the even field of the digital video signal, and a multiplexer for multiplexing the left and right eye video signals respectively generated from the first and second field memory devices to generate a three dimensional digital video signal.
