    The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale. Notice that some have a fixed intensity, while the illuminated period is variable. This is a kind of pulse-width modulation. Others can vary the actual intensity in response to the input signal.

    en.wikipedia.org/wiki/Quantum_dot_display

    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 ...

    en.wikipedia.org/wiki/LED-backlit_LCD

    To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. The quantum dots may be in a separate layer as ...

    Can have poor brightness, especially when most of the picture is white [5] Electro-magnetic radiation emission Can emit a small amount of X-ray radiation. Only emits non-ionizing radiation. [39] Emits strong radio frequency electromagnetic radiation [40] None, although control circuitry may emit radio interference Size Up to 43 in (1.1 m) [41]

  7. Quantum dot - Wikipedia

    en.wikipedia.org/wiki/Quantum_dot

    Quantum dot displays use blue-emitting LEDs rather than white LEDs as the light sources. 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.
