A quantum dot display is a
display device that uses
quantum dots (QD), semiconductor
nanocrystals which can produce pure monochromatic red, green, and blue light.
''Photo-emissive'' quantum dot particles are used in LCD backlights and/or display color filters. Quantum dots are excited by the blue light from the display panel to emit pure basic colors, which reduces light losses and color crosstalk in color filters, improving display brightness and
color gamut. Light travels through QD layer film and traditional RGB filters made from color pigments, or through QD filters with red/green QD color converters and blue passthrough. Although the QD color filter technology is primarily used in
LED-backlit LCDs, it is applicable to other display technologies which use color filters, such as blue/UV

MicroLED display panels. LED-backlit LCDs are the main application of photo-emissive quantum dots, though blue OLED panels with QD color filters are being researched.
''Electro-emissive'' or ''electroluminiscent'' quantum dot displays are an experimental type of display based on quantum-dot light-emitting diodes (QD-LED; also EL-QLED, ELQD, QDEL). These displays are similar to
active-matrix organic light-emitting diode (AMOLED) and
MicroLED displays, in that light would be produced directly in each pixel by applying electric current to inorganic nano-particles. Manufacturers asserted that QD-LED displays could support large, flexible displays and would not degrade as readily as OLEDs, making them good candidates for
