Wide color gamut LCD with a quantum dot backlight.
We analyze the color performance and system efficiency of three commonly employed liquid crystal display modes with a blue LED-pumped red and green quantum dots (QDs) backlight. Based on the measured QD emission spectra, we can achieve 115% color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as conventional backlights. Next, we apply multi-objectiv...
متن کاملColor performance of an MVA-LCD using an LED backlight
Ruibo Lu (SID Member) Xiangyi Nie Shin-Tson Wu (SID Fellow) Abstract — The color performance, including color gamut, color shift, and gamma curve, of a multidomain vertical-alignment (MVA) liquid-crystal display (LCD) using an LED backlight are calculated quantitatively. Simulation results indicate that an LED backlight exhibits better angular color uniformity and smaller color shifts than a CC...
متن کاملLED-backlight feedback control system with integrated amorphous-silicon color sensor on an LCD panel
Ki-Chan Lee Seung-Hwan Moon Brian Berkeley Sang-Soo Kim Abstract — Thin-film-transistor liquid-crystal displays (TFT-LCDs) have the largest market share of all digital flat-panel displays. An LCD backlighting system employing a three-color red-green-blue lightemitting diode (RGB-LED) array is very attractive, considering its wide color gamut, tunable white point, high dimming ratio, long lifeti...
متن کاملColor shift reduction of a multi-domain IPS-LCD using RGB-LED backlight.
Color gamut and static and dynamic color shifts of a multi-domain in-plane-switching liquid crystal display (IPS LCD) are calculated quantitatively using RGB (red, green, and blue) light-emitting diodes (LEDs) and cold-cathode fluorescent lamp (CCFL) backlights. Simulation results indicate that the LED backlight exhibits a wider color gamut, better angular color uniformity, and 2-4X smaller sta...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
