Structure and application of polarizer film for thin-film-transistor liquid crystal displays

Process Optimization of Deposition Conditions for Low Temperature Thin Film Insulators used in Thin Film Transistors Displays

Deposition process for thin insulator used in polysilicon gate dielectric of thin film transistors are optimized. Silane and N2O plasma are used to form SiO2 layers at temperatures below 150 ºC. The deposition conditions as well as system operating parameters such as pressure, temperature, gas flow ratios, total flow rate and plasma power are also studied and their effects are discussed.  The p...

Low voltage blue-phase liquid crystal displays

A protrusion electrode structure is proposed to dramatically lower the operation voltage of the emerging blue-phase liquid crystal displays BP-LCDs . Simulation results indicate that the generated horizontal electric field is not only strong but also penetrates deeply into the bulk LC layer. As a result, a low voltage 10 Vrms and reasonably high transmittance 70% BP-LCD can be achieved. This ap...

Organic Thin-Film Transistor-Driven Polymer-Dispersed Liquid Crystal Displays on Flexible Polymeric Substrates

P-24: High-Temperature (250°C) Amorphous-Silicon TFT’s On Clear Plastic Substrates

Amorphous silicon (a-Si) thin film transistors (TFT’s) were fabricated on free-standing, clear plastic substrates with a maximum process temperature of up to 250°C. An a-Si TFT backplane for active matrix OLED (AMOLED) application was also made on such substrates. The performance of both the TFT’s and the AMOLED backplane are excellent. These results will enable the fabrication of flexible AMLC...

Defect inspection of patterned thin film transistor-liquid crystal display panels using a fast sub-image-based singular value decomposition

Thin film transistor-liquid crystal displays (TFT-LCDs) have become increasingly attractive and popular as display devices. A machine vision approach is proposed for automatic inspection of microdefects in patterned TFT-LCD surfaces. The proposed method is based on a global image reconstruction scheme using singular value decomposition. A partition procedure that separates the input image into ...
