A new liquid crystal display (LCD) which eliminates the need for a conventional output polarizer is discovered. The display comprises only a liquid crystal (LC) cell, a single input polarizer, a reflector placed behind the cell, and a retardation film placed between the reflector and the cell. A Jo.....

This invention discloses an alternative approach of electrically tuning silicon-based waveguide-coupled microresonators that employs photoaligned liquid crystals as cladding layers. Planar optical microresonators that partially confine light and support sharp optical resonances have long been demon.....

Display is a large and still continuously expanding market. Flat-panel display is the dominating segment in the industry which involves the use of active-matrix driving technology. In conventional active matrix displays, thin film transistors (TFTs) are formed by amorphous silicon (a-Si). However, i.....

A RFID (Radio Frequency Identification) tag with an electromagnetic band gap substrate is introduced to improve the performance of the RFID tag. The electromagnetic band gap substrate acts as a reflector to reflect electromagnetic wave emitted from RFID antenna. This reflected phase of electromagnet.....

Organic electroluminescent or organic light emitting diode (OLED) devices are light emitting devices that are based on the passage of current through one or multiple organic thin layers. This invention proposed a new method of treatment of the transparent conducting anode layer which will therefore .....
