What does qled screen mean?

qled screen is a type of LED screen. The Q stands for quantum dot technology. It is based on the original LCD TV and adds a layer of quantum dot material between the backlight module and the image module. , to improve the color purity of the backlight. The advantage of this technology is a higher color gamut and stronger color purity.

What does qled screen mean?

qled screen is a type of LED screen. QLED has always been a selling point of Samsung TVs. The Q stands for quantum dot technology. Based on the original LCD TV, a layer of quantum dot material is added between the backlight module and the image module to improve the color purity of the backlight. Lifting is a bit similar to the color paper and soft light paper that our lighting teachers usually use. The advantage of this technology is that the color gamut is higher and the color purity is stronger.

QLED (Quantum Dot Light Emitting Diodes, quantum dot light-emitting diodes) refers to quantum dots (Quantum Dots) named by Yale University physicist Mark Reed Quantum dots are made of extremely tiny semiconductor nanocrystals that are invisible to the naked eye. Generally speaking, quantum dots are composed of zinc, cadmium, selenium and sulfur atoms.

It is also a particle with a particle size of less than 10 nanometers. If it is made into a thin layer of quantum dots and the layer is placed in the backlight module (BLU, Backlight Unit) of the liquid crystal display (LCD) In order to reduce the loss of backlight brightness and the color crosstalk of RGB color filters (Cross talk) compared to LCDs that do not use quantum dot thin layers, thereby achieving better backlight utilization. And a way to enhance the advantages of the display color gamut space (Color gamut), and the application of this method is also used in white light, blue light or ultraviolet (UV) organic light-emitting diode (OLED) displays with color filter designs or TV equipment.
