Patent
Method of achieving high pretilt angles in a lilquid crystal cell
TL;DR: In this paper, a method of obtaining high pretilt angles of predetermined values in a liquid crystal cell is disclosed, where appropriate amounts of compatible homogeneous and homeotropic alignment materials are mixed with special treatment methods to achieve the desired results.
Patent
Anode for organic light emitting diode
TL;DR: In this paper, an organic light emitting diode consisting of multiple organic layers, disposed between a transparent conducting anode and metallic cathode, was provided with a metal fluoride layer to enhance the overall performance of the device.
Journal ArticleDOI
On the formation of solid state crystallized intrinsic polycrystalline germanium thin films
TL;DR: In this article, a two-step heat treatment process was employed to crystallize low pressure deposited thin films of amorphous germanium and high Hall effect electron mobility was obtained.
Patent
Polycrystalline silicon as an electrode for a light emitting diode and method of making the same
TL;DR: In this article, metal induced polycrystallized silicon is used as the anode in a light emitting device, such as an OLED or AMOLED, and a thin film transistor can be formed onto the poly crystalized silicon anode.
Journal ArticleDOI
Generalized mixed-mode reflective LCDs with large cell gaps and high contrast ratios
TL;DR: In this paper, a generalized mixed twisted-nematic/birefringent effect mode reflective LCD is presented, which encompasses all previously published reflective nematic LCD modes and is clearly shown on the parameter space diagrams.
