2D/3D switchable image display device

摘要

A two-dimensional (2D)/three-dimensional (3D) switchable image display device is provided. The 2D/3D switchable image display device forms gradation of an image in a light modulation panel, provides color to light beams that penetrate a plurality of electro-wetting prisms arranged in correspondence to the plurality of pixels of the image, and adjusts the direction of the light beam such that the light beams of the pixels of the image are directed towards at least two different view zones in a 3D mode and such that the light beams maintain their paths in a 2D mode.

1. A two-dimensional/three-dimensional (2D/3D) switchable image display device comprising:
a backlight unit configured to emit light; a light modulation panel configured to modulate the light emitted from the backlight unit based on image information and for forming image gradation; an electro-wetting prism array comprising a plurality of electro-wetting prisms that are arranged to correspond to a plurality of pixels of the image in a display panel, for providing color to light beams that penetrate the plurality of electro-wetting prisms, and for adjusting the direction of the light beams; and a control unit configured to control the backlight unit and the electro-wetting prism array such that the light beams of the plurality of pixels of the image are directed towards at least two different view zones in a 3D mode, and such that the light beams of the plurality of pixels of the image maintain the paths of the light beams in a 2D mode, wherein the electro-wetting prism array further comprises a barrier wall formed between each of the plurality of electro-wetting prisms, and the barrier wall is formed of a black material for blocking light.
