Aggregation-Induced Emission: Together We Shine, United We Soar!

Luminogenic materials with aggregation-induced emission (AIE) attributes have attracted much interest since the debut of the AIE concept in 2001. In this critical review, recent progress in the area of AIE research is summarized. Typical examples of AIE systems are discussed, from which their structure–property relationships are derived. Through mechanistic decipherment of the photophysical processes, structural design strategies for generating new AIE luminogens are developed. Technological, especially optoelectronic and biological, applications of the AIE systems are exemplified to illustrate how the novel AIE effect can be utilized for high-tech innovations (183 references).

Fluorinated indium-gallium-zinc oxide thin-film transistor with reduced vulnerability to hydrogen-induced degradation

We investigate the switching bistability based on the interaction between dynamic flow and director rota-tion in twisted nematic liquid crystal cells. Numerical calculation shows that there exists a general type of bistable twisted director configurations. Two specific cases are verified experimentally. Keywords: bistability, twisted nematic, liquid crystal displays, backflow, switching 1. INTRODUCTION Twisted nematic (TN) and super-twisted nematic (STN) liquid crystal displays (LCD) are used widelyin many information display systems. Recently, a bistable TN (BTN) LCD has been demonstrated 1,2• This BTN is based on a gross mismatch of the natural twist of the liquid crystal director and the rubbingboundary conditions of the two LC cell surfaces. If the LC cell alignment favors a -twist, then for somevalue of natural helical pitch P, the LC cell can exist either in the -twist state or the (4 + 2ir)-twiststate. Roughly speaking, in the absence of pretilt of the director, the natural twist of the LC cell shouldbe about 4 + ir in order for bistability to occur. Hence the d/P ratio, where d is the LC cell thickness,

Switching behavior in bistable twisted nematic liquid crystal displays

High‐Performance Polycrystalline Silicon Thin‐Film Transistors without Source/Drain Doping by Utilizing Anisotropic Conductivity of Bridged‐Grain Lines

A generalized mixed twisted nematic/birefringent effect mode is presented for reflective liquid crystal displays with only one polarizer. This new MTB mode encompasses all previously published reflective nematic liquid crystal display modes and is clearly shown on the parameter space diagrams. The invention of how to obtain operating conditions of this generalized mixed mode display is discussed. For any given angle between the polarizer and the input director of the liquid crystal cell, a unique range of values of the twist angle and the retardation dΔn for efficient reflection and low dispersion is defined.

Reflective active matrix liquid crystal displays with mixed twisted nematic and birefringent modes

In this letter, degradation of polycrystalline silicon (poly-Si) thin-film transistors (TFTs) under “driving” stress is characterized and analyzed for the first time. Dynamic hot carrier (HC) effect, related to pulse falling time, dominates device degradation. To suppress such “driving”-stress-induced dynamic HC degradation, a bridged-grain (BG) structure is applied to the active channel of poly-Si TFTs. Due to the lateral electric field reduction at source/drain junctions, “driving”-stress-induced dynamic HC degradation is significantly improved by the BG structure. Incorporated with transient simulations, the degradation mechanism is elucidated.
