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. Quantum dots are excited by the blue light from the display panel to emit pure basic ...
Quantum dots are theoretically described as a point-like, or zero dimensional (0D) entity. Most of their properties depend on the dimensions, shape, and materials of which QDs are made. Generally, QDs present different thermodynamic properties from their bulk materials. One of these effects is melting-point depression.
Many expect that quantum dot display technology can compete or even replace liquid crystal displays (LCDs) in near future, including the desktop and notebook computer spaces and televisions. These initial applications alone represent more than a $8-billion addressable market by 2023 for quantum dot-based components.
Nanocrystalline material. Science portal. Technology portal. v. t. e. Carbon quantum dots also commonly called carbon nano dots or simply carbon dots (abbreviated as CQDs, C-dots or CDs) are carbon nanoparticles which are less than 10 nm in size and have some form of surface passivation. [1][2][3]
A quantum dot laser is a semiconductor laser that uses quantum dots as the active laser medium in its light emitting region. Due to the tight confinement of charge carriers in quantum dots, they exhibit an electronic structure similar to atoms. Lasers fabricated from such an active media exhibit device performance that is closer to gas lasers ...
LED-backlit LCD. An Apple iPod Touch disassembled to show the array of white-edge LEDs powered on with the device. 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 ...
