P-151: Color Filter Liquid-Crystal-on-Silicon Microdisplays
TL;DR: In this article, a single-panel WXGA color projector based on color filter microdisplay technology was demonstrated, where the color filters are aligned on a separate glass plate and aligned to pixels on a TFT plate.
Journal ArticleDOI
From a fluorescent chromophore in solution to an efficient emitter in the solid state.
Yang Liu,Yang Liu,Yun Lv,Xiying Zhang,Shuming Chen,Jacky Wing Yip Lam,Ping Lu,Ryan T. K. Kwok,Hoi Sing Kwok,Xutang Tao,Ben Zhong Tang,Ben Zhong Tang +11 more
TL;DR: A highly efficient solid-state emitter with a fluorescence quantum efficiency of unity in the aggregated state was obtained using the planar PAH fluoranthene as a building block to bestow PAHs a luminescent ability in the solid state.
Journal ArticleDOI
A Physical Model for Metal–Oxide Thin-Film Transistor Under Gate-Bias and Illumination Stress
TL;DR: In this article, a more physically based model was formulated, incorporating the photogeneration, transport, and trapping of holes, and the model parameters of generation energy barrier, hole mobility and trapping time constant were extracted from the measured gate-bias dependent turn-on voltage shift.
Journal ArticleDOI
Reflective Supertwisted Nematic Liquid Crystal Displays
TL;DR: In this article, the rear polarizer has been removed and no retardation film is used for dispersion compensation, which can potentially yield higher brightness than conventional supertwisted nematic (STN) displays.
Journal ArticleDOI
Synthesis, Light Emission, and Photovoltaic Properties of Perylene-Containing Polyacetylenes
Jianli Hua,Jacky Wing Yip Lam,Xiaoming Yu,Lijun Wu,Hoi Sing Kwok,Kam Sing Wong,Ben Zhong Tang,Ben Zhong Tang +7 more
TL;DR: Perylene (Py)-containing polyacetylenes with different skeleton structures are synthesized in satisfactory yields by Rh-catalyzed polymerization (for P1 and P2) and polymer reaction (forP3) as mentioned in this paper.
