Patent ID: 8064000

Claim:
A parallax-barrier module comprising: a Liquid-Crystal layer (LC layer) including cells arranged in a cell type matrix structure to form barriers of a horizontal or a vertical direction according to a predetermined control method; a controller for controlling said cells of said LC layer in order to form said barriers of the horizontal or the vertical direction, by turning said cells on or off selectively according to said control method; a lower layer formed between said LC layer and a predetermined display module in order to dispose said LC layer and said controller at a position off from said display module by a predetermined distance; an upper layer formed on the top of said LC layer in order to dispose said LC layer and said controller; and a polarizer formed on the top of said upper layer, and visualizing said barriers formed on said LC layer by controlling a polarization angle of light, wherein said light is emitted from said display module and passing through said lower layer, said LC layer and said upper layer, wherein said cell type matrix structure includes: a first cell row having a first cell whose width*length is a*c and a second cell whose width*length is b*c arranged in alternately repeated manner along the horizontal direction; and a second cell row having a third cell whose width*length is a*d and a fourth cell whose width*length is b*d in alternately repeated manner along the horizontal direction, wherein said first cell row and said second cell row are arranged in alternately repeated manner along the vertical direction, and wherein said arranged fourth cells whose width*length is b*d maintain off, wherein said length d of said arranged fourth cells is an interval of said barriers of the horizontal direction, and wherein said width b of said arranged fourth cells is an interval of said barriers of the vertical direction.
