Vladimir G. Chigrinov,Abhishek Kumar Srivastava,Eugene P. Pozhidaev,Guo Qi,Ma Ying,Hoi Sing Kwok +5 more
TL;DR: In this paper, photoaligning layers in FLC cells are used to achieve fast response time, high contrast ratio, and high contrast ratios for pico-projectors with high resolution in the field sequential color (FSC) microdisplays.
Patent
Transflective liquid crystal device and method of manufacturing the same
TL;DR: In this article, the construction of electrodes for liquid-crystal displays using larger grain lower absorption (LGLA) poly-Si showing an absorptivity below 20% in the visible light region is described.
Journal ArticleDOI
Enhancing the optical and electrical properties of AlGaN ultraviolet-C micro-LED via a hybrid scheme of plasma and chemical treatment
TL;DR: In this paper , three types of 20 × 20 µm2 UV-C micro-LEDs with the peak wavelength of 269 nm were fabricated by different etching strategies, including an inductively coupled plasma (ICP), post-ICP tetramethylammonium hydroxide, and a hybrid scheme combining plasma and chemical treatment.
Journal ArticleDOI
P-22: Top-Gate Thin Film Transistor with ZnO:N Channel Fabricated by Room Temperature RF Magnetron Sputtering
TL;DR: In this article, a top-gate thin-film transistor (TFT) with ZnO doped nitrogen (ZnO:N) channel fabricated by room temperature rf magnetron sputtering is demonstrated.
Journal ArticleDOI
A novel approach to LCD optimization
TL;DR: A novel approach to optimization liquid‐crystal displays (LCDs) is presented, which allows for a prediction with a high accuracy for the best results, which can be obtained for one or the other configuration of the polarizers and phase retarders in various electro‐optical modes, if the LC parameters and the operating voltages are fixed.
