Stereoscopic display device

摘要

Disclosed is stereoscopic display device in which barriers crossing each other are formed on two substrates and voltage is applied to the barrier pattern to drive liquid crystals between the two substrates such that one of the barriers is selectively driven, enabling selective implementation of 3-dimensional (3D) display and dual view display.

主权项

1. A stereoscopic display device, comprising:
a display panel including a plurality of red, green, and blue pixels; and a barrier cell provided above the display panel and including first and second substrates opposite each other, a plurality of first electrodes formed on the first substrate in a first direction, a plurality of second electrodes formed on the second substrate in a second direction crossing the first direction, and a liquid crystal layer between the first and second substrates, wherein the barrier cell functions as a first barrier or a second barrier according to voltage application such that 3-dimensional (3D) display is implemented during functioning of the barrier cell as the first barrier and dual view display is implemented during functioning of the barrier cell as the second barrier to allow viewers located at different positions to perceive different images, wherein a common voltage is applied to the second electrodes and one first drive voltage greater than the common voltage is applied to the first electrodes during functioning of the barrier cell as the first barrier, wherein a common voltage is applied to the first electrodes and one second drive voltage greater than the common voltage is applied to the second electrodes during functioning of the barrier cell as the second barrier, wherein the first electrodes or the second electrodes function as light shade patterns during voltages are applied to the barrier cell, wherein the first electrodes are equidistantly arranged and have the same width and the second electrodes are equidistantly arranged and have the same width, wherein the first electrodes are structured on a per-pixel basis, each of the first electrodes overlapping pixels that are two of the three colors of red, green, and blue, and pixels that are two of the three colors of red, green, and blue are exposed by each of a plurality of slits formed between the first electrodes, and wherein the first electrodes and the second electrodes have different widths and distances from each other so that the first barrier and the second barrier have different viewer's viewing distances.
