Patent ID: 8373684

Claim:
A high resolution 2D-3D switchable autostereoscopic display apparatus comprising: a backlight unit emitting light; a spatial light modulator comprising a plurality of cells, the cells being arranged two-dimensionally and comprising left eye regions and right eye regions that are each independently switchable between a transparent state and an opaque state; a lenticular lens sheet separating and emitting light passed through the spatial light modulator to a left eye viewing zone and a right eye viewing zone; and an image display panel displaying an image, wherein the spatial light modulator is divided into a plurality of horizontal segments that are sequentially switched from top to bottom during vertical scanning, by the image display panel, of a frame of the image, in synchronization with a vertical synchronization signal of the image display panel, and wherein the spatial light modulator is a transmissive liquid crystal device that includes electrodes having a parallax barrier pattern that correspond to the cells, and liquid crystal controlled according to a voltage applied to the electrodes.
