TFT or Thin Film Transistor array is a technology used in LCD or Liquid Crystal Display. TFT means that the display consists of transistors placed on a substrate at high density, it is called Active Matrix LED. It will be different from Passive Matrix LED. A TFT substrate is composed of a matrix of pixels and ITO electrode (Indium Tin Oxide, a transparent electric conducting film) each with a TFT device and is so called array. Thousands or millions of these pixels together create an image on the display.

Working Principle
TFT displays are equipped with a backlight (LEDs) that illuminates a layer of liquid crystals. These are connected to so-called thin-film transistors, which control the alignment of the liquid crystals using electrical energy.
Depending on the pixel technology, the electrodes are either arranged opposite each other (with twisted nematic (TN) and vertical alignment (VA)) or in one plane (with in-plane switching (IPS)).
Product Description
Through quantum dot technology, the color saturation is increased from 50% to 100% to achieve brilliant colors.
High stability of the picture, the display effect is very wonderful. High contrast ratio can reach more than 800, rich color levels bring more impactful visual effects.
