We developed a 5.5 inch, VGA (640×480×RGB), stereoscopic 3D display using a wire grid polarizer on patterned retarder. The proposed stereoscopic display uses the existing TFT array panel and a color filter on a wire grid polarizer on patterned retarder. Since a wire grid polarizer is placed adjacent to the LC layer, there is no limitation on viewing angle and viewing distance. Therefore, it is possible for many people to watch stereoscopic display simultaneously.

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.

A nonthermal plasma produced by the streamer corona discharge at an atmospheric pressure was investigated for the treatment of fluorocarbon. The effective treatment of fluorocarbons was performed by controlling the discharge parameters of the plasma. The decomposition rate of fluorocarbon was investigated by varying (a) discharge modes, (b) dilution gases and (c) discharge characteristics, that is, applied voltage V A-K of the main discharge gap and its steepness dV A-K =dt. The maximum decomposition rate of 92% was achieved by the streamer corona discharge.

We have developed a low cost AM backplane using non‐laser polycrystalline silicon (poly‐Si) having inverse staggered TFT. The thin‐film transistors (TFTs) have a center‐offset gated structure to reduce the leakage current without scarifying the on‐currents. A center‐offset length of the TFTs has 3 μm for both switching and driving TFTs. Finally, we have made a 2.2 inch QQVGA (160 × 120) active‐matrix organic light emitting diode (AMOLED) display with conventional 2T 1C pixel circuits.
