Po-Tsun Liu Award Candidate A-Si Gate Driver for High Resolution Display


This paper presents a novel gate driver circuit which is suitable for narrow-bezel application. The proposed gate driver is designed by amorphous silicon (a-Si) technology. The so-called bi-side gate driver is divided into two parts, laying on two sides of the panel to drive the odd lines and the even lines of pixel arrays, respectively. The simulated result reveals that the signal could output successfully to 960 stages

Chieh Lo Award Candidate Hydrogen-Induced Effect on the Scaled-Down Channel Length of Top-Gate Amorphous InGaZnO Thin Film Transistors


Hydrogen diffused from the inter layer dielectric to channel can passivate defects and form high carrier concentration region at the edge of a-IGZO channel. As the channel length scales down, the proportion of high hydrogen incorporated edge region in a-IGZO channel is increased which leads to the better channel quality.

Yi Tang Award Candidate Opto-thermal addressing bistable and rewritable liquid crystal device based on gelator-doped liquid crystal in poly(N-vinylcarbazole) film-coated liquid crystal cell


This work demonstrates a bistable and rewritable liquid crystal (LC) device based on gelator-doped LC in poly(N-vinylcarbazole) film-coated LC cell. The performance of bistability and rewritability are achieved by forming the rubbery LC/gel mixture at room temperature.

Yi Chen Chen Award Candidate The Properties of Dynamic Drive Scheme for Bistable Cholesteric Liquid Crystal Display


A system for analyzing the dynamic drive scheme (DDS) of a cholesteric liquid crystal (CLC) display is developed.

This method for CLC has great potential to be used for color reflective bistable energy-saving display.
