25.3: Auto‐Stereoscopic TFT‐LCD with LC Parallax Barrier on Wire Grid Polarizer

Abstract

We have developed a 5.5 inch auto‐stereoscopic TFT‐LCD (640 × 480 × RGB) display with LC (liquid crystal) parallax barrier having the pitch of 58 μm on the back of wire grid polarizer substrate. The auto‐stereoscopic display of the proposed structure can be 2D/3D convertible LCD, indicating that it can provide us with 3D display as well as conventional 2D display. The auto‐stereoscopic 3D display with wire‐grid polarizer has the advantages of short viewing depth and thinness.

“…Some ideas have been presented to prevent this decrease in brightness. For example, a method of using a lens instead of a barrier and a method of applying a wire grid polarizer have been reported . The third drawback is 3D crosstalk.…”

“…In recent days, three-dimensional (3-D) display technologies have been actively studied. [1][2][3][4] Among these 3-D display technologies, 3-D stereoscopic technologies for flat-panel displays use a principle that projects separate images on each eye after separating the images for the left and right eye for the realization of the 3-D effect, and these are classified into autostereoscopic [5][6][7] and stereoscopic [8][9][10] methods based on the use of glasses. The autostereoscopic method has merit in that it does not require glasses when watching a 3-D display, but the viewing region is narrow and the resolution is reduced.…”

“…These stereoscopic 3D displays require special glasses, but become widespread in home televisions and movie theaters because the users can naturally see 3D images. These days, auto-stereoscopic 3D displays also attract attention [2]. Auto-stereoscopic 3D displays allow the users to see 3D images without wearing special glasses.…”
