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 ...

Nick Holonyak Jr. (/ h ʌ l ɒ n j æ k / huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator.He is noted particularly for his 1962 invention and first demonstration of a semiconductor laser diode that emitted visible light.
The converting part of the emitted light is converted into pure green and red light by the corresponding color quantum dots placed in front of the blue LED or using a quantum dot infused diffuser sheet in the backlight optical stack. Blank pixels are also used to allow the blue LED light to still generate blue hues.
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 ...
