Journal ArticleDOI
Fringe field effect free high-resolution display and photonic devices using deformed helix ferroelectric liquid crystal
TL;DR: The photonic industry limiting the pixel per inch (PPI) to ~450 as mentioned in this paper, which is one of the biggest bottlenecks for the display, and this is the case for AR/VR headsets.
Journal ArticleDOI
Alleviate microcavity effects in top-emitting white organic light-emitting diodes for achieving broadband and high color rendition emission spectra
Shuming Chen,Hoi Sing Kwok +1 more
TL;DR: In this paper, a tri-cathode-layer top-emitting WOLED with evenly separated red, green and blue emission peaks has been shown to achieve an efficiency of 23cd/A, 10.5lm/W and a high color rendering index of 85.
Journal ArticleDOI
Aggregate‐induced emission in light‐emitting liquid crystal display technology
TL;DR: In this article, the authors studied the aggregate-induced emission effect of a luminescent liquid crystalline molecule TPE-PPE as a luminophore dopant in liquid crystal displays.
Journal ArticleDOI
Active matrix field sequential color electrically suppressed helix ferroelectric liquid crystal for high resolution displays
Liangyu Shi,Abhishek Kumar Srivastava,Alex Cheung,Chia-Ting Hsieh,Ching-Lang Hung,Ching-Hsiang Lin,Ching-Huan Lin,Norio Sugiura,Chia-Wei Kuo,Vladimir G. Chigrinov,Hoi Sing Kwok +10 more
TL;DR: In this paper, a 3-inch 250ppi active matrix field sequential color electrically suppressed ferroelectric liquid crystal (ESHFLC) display is presented, which has a high contrast ratio over 10K:1.
Journal ArticleDOI
CO2 laser‐induced melting of indium antimonide
TL;DR: In this article, the authors used CO2 laser pulses to identify the following sequence of events in high power laser-semiconductor interaction: generation of a dense (≳1018 cm3) plasma, melting of the crystal by free carrier absorption, formation of surface ripples at the breakdown threshold, and formation of a crater at higher intensities.
