A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
Samsung Display enabled the first mass-production of OLED and quantum dot displays and aims to develop next-generation technology such as slidable, rollable and stretchable panels. The company was established as S-LCD Corporation in April 2004 in Chungcheongnam-do as a joint venture between Samsung Electronics (51% share) and Sony Corporation ...

The availability of larger screen sizes at more affordable prices has driven consumer demand. For example, Samsung, a leading electronics manufacturer, introduced its first 98-inch (250 cm) television in 2019 with a price tag of $99,000. In 2024, the company will offer four 98-inch (250 cm) models starting at $4,000.
The classical treatment of both two-dimensional and three-dimensional quantum dots exhibit electron shell-filling behavior. A "periodic table of classical artificial atoms" has been described for two-dimensional quantum dots. [125]
The core and the shell are typically composed of type II–VI, IV–VI, I-III-VI, and III–V semiconductors, with configurations such as CdS/ZnS, CdSe/ZnS, CuInZnSe/ZnS, CdSe/CdS, and InAs/CdSe (typical notation is: core/shell) [2] Organically passivated quantum dots have low fluorescence quantum yield due to surface related trap states. [3]
Silicon quantum dots are metal-free biologically compatible quantum dots with photoluminescence emission maxima that are tunable through the visible to near-infrared spectral regions. These quantum dots have unique properties arising from their indirect band gap , including long-lived luminescent excited-states and large Stokes shifts .
This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance. Quantum processors are difficult to compare due to the different architectures and approaches.
