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.

Abstract— A low‐cost active‐matrix backplane using non‐laser polycrystalline silicon (poly‐Si) having inverse‐staggered TFTs with amorphous‐silicon (a‐Si) n+ contacts has been developed. The thin‐film transistors (TFTs) have a center‐offset gated structure to reduce the leakage current without scarifying the ON‐currents. The leakage current of the center‐offset TFTs at Vg = −10 V is two orders of magnitude lower than those of the non‐offset TFTs. The center‐offset length of the TFTs was 3 μm for both the switching and driving TFTs. A 2.2‐in. QQVGA (1 60 × 1 20) active‐matrix organic light‐emitting‐diode (AMOLED) display was demonstrated using conventional 2T + 1C pixel circuits.

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 describe a new surface treatment to obtain optical films for liquid crystal display (LCD) applications. The films consist of a phase-separated layer including a fluorine-containing (FC) compound and a widely used polymer resin for providing a hard coating after surface treatment of the optical film. The major features of the resulting configuration are high durability with a good hardness of above 4H and a surface that allows oily contaminants such as ink and fingerprints to be easily removed by gentle dry wiping, owing to the antismudge function of the FC compound with a low surface energy.
