This technology has also been called true QLED display, [63] and Electroluminescent quantum dots (ELQD,QDEL, EL-QLED). [64] [65] The structure of a QD-LED is similar to the basic design of an OLED. The major difference is that the light emitting devices are quantum dots, such as cadmium selenide (CdSe) nanocrystals. A layer of quantum dots is ...
OLED lighting offers several advantages over LED lighting, such as higher quality illumination, more diffuse light source, and panel shapes. [167] Philips Lighting has made OLED lighting samples under the brand name "Lumiblade" available online [ 169 ] and Novaled AG based in Dresden, Germany, introduced a line of OLED desk lamps called ...
OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors.

An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. [1] LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.
1987 optical micro-electro-mechanical technology that uses a digital micromirror device. While the Digital Light Processing (DLP) imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997.
Ching Wan Tang (Chinese: 鄧青雲; pinyin: Dèng Qīngyún; born July 23, 1947) is a Hong Kong–American physical chemist.He was inducted into the National Inventors Hall of Fame in 2018 for inventing OLED (together with Steven Van Slyke), and was awarded the 2011 Wolf Prize in Chemistry. [1]
