Abstract
A parallax-barrier comprises a Liquid-Crystal layer (LC layer) including pixels that form a barrier according to a control method. A controller controls the pixels of the LC layer to form a barrier pattern, by turning pixels on or off according to the control method. A lower layer is formed between the LC layer and a display module to dispose the LC layer and controller at a position off the display module by a predetermined distance. An upper layer is formed on the LC layer to dispose the LC layer and controller, and a polarizer on the upper layer, and visualizing the barrier according to the barrier pattern on the LC layer by controlling polarization angle of the light. The light passes through the lower layer, LC layer and upper layer. Stereoscopic images that are rotated in the horizontal/vertical direction can be displayed using the parallax-barrier and stereoscopic image.
