What is TFT-LCD Display?

TFT-LCD Display(Thin film transistor liquid crystal display，Abbreviated as TFT-LCD) is one of LCD displays,it uses thin film transistor technology to improve image quality.Although TFT-LCD is collectively referred to as LCD,However, it is an active matrix LCD, which is used in televisions, flat panel displays and projectors.

1.Brief Introduction:

  In short, TFT-LCD screen is a layer of liquid crystal sandwiched between two glass substrates,the upper glass substrate is connected with the color filter、and the lower glass is inlaid with transistors.When the current passes through the transistor, the electric field changes,deflection of liquid crystal molecules,to change the polarization of light,then the polarizer is used to determine the light and dark state of the pixel.

  In addition, the upper glass is bonding with the color filter,each pixel contains red, blue and green,these red, blue and green pixels constitute the image on the panel.

  Thin film transistor liquid crystal display technology is an ingenious combination of microelectronic technology and LCD technology.Transplant the technology of micro electronic fine processing on single crystal to the processing of thin film transistor (TFT) array on large area glass,then the array substrate and another substrate with color filter film are combined to form a liquid crystal box by using mature liquid crystal display (LCD) technology,after that, the liquid crystal display device is finally formed through subsequent processes (such as polarizer coating).
