Journal ArticleDOI
11.4: Coupling Efficiency Enhancement of Organic Light Emitting Devices with Refractive Microlens Array on High Index Glass Substrate
TL;DR: In this article, an approach to increase the coupling efficiency of organic light emitting diodes (OLEDs) is studied, where refractive microlens arrays are formed on the high refractive index glass substrate by etching the glass using reflowed photoresist as mask.
Journal ArticleDOI
Complex Nanoscale-Ordered Liquid Crystal Polymer Film for High Transmittance Holographic Polarizer.
TL;DR: A special design of a complex-ordered liquid crystal polymer film is developed into a holographic polarizer, which provides a simple solution to make LEDs polarized.
Patent
Method and device for stand-off laser drilling and cutting
TL;DR: In this article, a free-running laser beam creates a melt on the target and then a Q-switched short duration pulse is used to remove the material through the creation of a laser detonation wave.
Journal ArticleDOI
Elevated-Metal–Metal-Oxide Thin-Film Transistor: Technology and Characteristics
TL;DR: In this paper, an elevated metal-metaloxide (EMMO) thin-film transistor (TFT) was proposed, which accommodates an etch-stop/passivation layer without increasing the mask count.
Journal ArticleDOI
Study of collisionless multiphoton absorption in S F 6 using picosecond C O 2 laser pulses
TL;DR: In this article, the dynamics of collisionless infrared multiphoton absorption in S${\mathrm{F}}_{6}$ was studied using picosecond C${O}}_{2}$ laser pulses, and it was found that at very high laser intensities, the absorption in the quasicontinuum has a considerable intensity dependence.
