2. Quantum dot - Wikipedia

   en.wikipedia.org/wiki/Quantum_dot

   This type of white light as the backlight of an LCD panel allows for the best color gamut at lower cost than an RGB LED combination using three LEDs. [ 107 ] Another method by which quantum dot displays can be achieved is the electroluminescent (EL) or electro-emissive method.

3. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Green electroluminescence from a point contact on a crystal of SiC recreates Round's original experiment from 1907. Close-up of a 1 watt red power led. Electroluminescence as a phenomenon was discovered in 1907 by the English experimenter H. J. Round of Marconi Labs, using a crystal of silicon carbide and a cat's-whisker detector.

   At CES 2017 Sony showcased the CLEDIS ™ (Crystal LED Integrated Structure) with a Crystal LED video wall approximately 32 by 9 feet (9.7 x 2.7 meter) with a resolution of 8000 x 2000 pixel. According to Sony, it is composed of single display modules measuring 17 7/8" (463.6mm) by 15 7/8" (403.2mm) each. The individual modules were not visible ...

5. Quantum dot display - Wikipedia

   en.wikipedia.org/wiki/Quantum_dot_display

   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 ...

6. Crystal oscillator - Wikipedia

   en.wikipedia.org/wiki/Crystal_oscillator

   A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. [1] [2] [3] The oscillator frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.

7. X-ray crystallography - Wikipedia

   en.wikipedia.org/wiki/X-ray_crystallography

   X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer can produce a three-dimensional picture of ...
