QLED
QLED is the abbreviation of Quantum Dot Light Emitting Diodes, which is a self-illuminating technology that does not require additional light sources. Quantum (Quantum Dots) are some extremely small semiconductor nanocrystals that cannot be seen by the naked eye, and are particles with a particle size of less than 10 nanometers. Quantum dots have a distinctive feature: whenever stimulated by light or electricity, quantum dots will emit colored light. The color of the light is determined by the composition, material, size and shape of the quantum dots, and its frequency can be adjusted by changing the size of the quantum dots. , shape and material to precisely adjust to achieve a variety of applications.
The structure of QLED is very similar to OLED technology, the main difference is that the light-emitting center of QLED is composed of quantum dots (Quantum dots) material. Its structure is that electrons (Electron) and holes (Hole) on both sides converge in the quantum dot layer to form photons (Exciton), and emit light through the recombination of photons.
The future direction of development is quantum display (QLED). Quantum Display emits light through particles as small as nanometers, which is much stronger than OLED. Now the quantum Display on the market is a pseudo-quantum Display. When will the real quantum Display be available? Still an unknown. Let us wait and see!
