45.3: Pentacene Organic Thin‐Film Transistor Integrated with Color Twisted Nematic Liquid Crystals Display (CTNLCD)

Abstract

Pentacene Organic Thin-Film Transistor (OTFT) integrated withColor Twisted Nematic Liquid Crystals Display (CTNLCD) has been developed. This display used photolithography, pentacene deposition, color filter and TNLC. In addition, we successfully develop the OTFT passivation layer process to avoid the damage of TNLC. Above these processes are integrated to manufacture the 3 inch CTNLCD panels with 64×128 pixels.

Influence of Surface Roughness on the Dynamics and Crystallization of Vapor-Deposited Thin Films

“…Finally, focusing on the surface roughness, the properties of materials under confinement are reported to be altered by the roughness of the substrate on which they are deposited. The surface roughness can directly influence the properties such as the adhesion, − hydrophobicity, , elastic modulus, electronic, magnetic, optical properties, − and a lot more. Thus, considering its practical applications, it is inevitable to understand the surface roughness’s influence on the properties of thin films.…”

Liquid-crystal displays using printed plastic TFT backplanes

“…1 In contrast to amorphous silicon, the processing of these polymer TFTs does not require such complex processes as vacuum deposition, photolithography, or any high-temperature steps. [1][2][3][4][5][6] One of the issues associated with the manufacture of liquid-crystal displays (LCDs) from polymer TFT backplanes is the instability of the backplanes' semiconductor and dielectric materials under the processing conditions required for standard LCD fabrication. In particular, plastic TFTs tend to degrade at the high temperatures required to cure the polyimide layers used to induce alignment in LC.…”
