An Integrator and Schmitt Trigger Based Voltage-to-Frequency Converter Using Unipolar Metal-Oxide Thin Film Transistors
Yuming Xu,Wei Zhong,Bin Li,Sunbin Deng,Fan Houbo,Zhaohui Wu,Lei Lu,Fion Sze Yan Yeung,Hoi Sing Kwok,Rongsheng Chen +9 more
TL;DR: In this article, the authors proposed a voltage-to-frequency converter (VFC) design using unipolar metal-oxide thin film transistor (TFT) technology, which has an integrator and Schmitt trigger based structure.
Journal ArticleDOI
Comb-on-plane switching electrodes for liquid-crystal displays
TL;DR: In this paper, a comb-on-plane switching (COPS) electrode design is proposed to improve the viewing angle of a high-definition display with a wide viewing angle.
Journal ArticleDOI
32.3: Metal‐Induced Unilaterally Crystallized Polycrystalline Silicon Thin‐Film Transistor Technology for Active‐Matrix Organic Light‐Emitting Diode Displays with Reduced Susceptibility to Cross‐Talk
TL;DR: In this paper, an improved active-matrix organic light-emitting diode (OLED) display was proposed and implemented, employing gate-modulated lightly-doped drain to suppress transistor leakage and to improve image quality.
Journal ArticleDOI
Dynamic Flow, Broken Surface Anchoring, and Switching Bistability in Three-terminal Twisted Nematic Liquid-crystal Displays
TL;DR: In this article, the switching bistability between the Φ and Φ+π twist states in liquid-crystal cells with a three-terminal electrode structure was investigated based on general nematohydrodynamic equations and a modeling potential of surface anchoring.
