A quantum dot display is a display device that uses quantum dots (QD), semiconductor nanocrystals which can produce pure monochromatic [a] red, green, and blue light. Photo-emissive quantum dot particles are used in LCD backlights or display color filters.
Another method by which quantum dot displays can be achieved is the electroluminescent (EL) or electro-emissive method. This involves embedding quantum dots in each individual pixel. These are then activated and controlled via an electric current application. [106]
Since each dot on the screen is lit by a single emitter, there is no need to steer or direct the beam as there is in a CRT. The quantum tunneling effect, which emits electrons across the slits, is highly non-linear, and the emission process tends to be fully on or off for any given voltage. This allows the selection of particular emitters by ...
Quantum Materials CEO Stephen Squires specifically claims his company's tetrapod technology works with fewer dots overall and better manufacturing tech to hit the lowest cost possible.
Quantum dot displays utilize quantum dots to produce pure monochromatic light. Most of the work designing LEDs based on silicon quantum dots have focused on electroluminescence of the silicon quantum dots. [45] [46] By changing the size of the SiQDs, the LED emission can be tuned from deep red (680 nm) to orange/yellow (625 nm). [47]
A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode-ray tubes , each tube producing a single sub-pixel, grouped in threes to form red-green-blue ...
