What is the difference between TFT and LCD?

Full name of TFT: Thin Film Transistor.The laptops and desktops we use now use relatively advanced TFT displays,these displays are composed of LCD pixels,it is driven by a thin film transistor integrated behind the pixel.Therefore, TFT display is also a kind of display device with source matrix.TFT type displays are the best among color LCD displays.

TFT monitors have many advantages:High responsiveness, high brightness, high contrast, etc.The display effect of TFT display is the closest to CRT display.TFT screens also often appear on the screens of major mobile phones,There are 65536 colors, 160000 colors and 16 million colors respectively, and the display effect is also excellent.

  TFT means that each LCD pixel on the LCD is driven by a thin film transistor integrated behind it.Thus, screen information can be displayed at high speed, high brightness and high contrast.

  The LCD(Liquid Crystal Display) is constructed by placing a LCD cell between two parallel glass substrates,TFT (thin film transistor) is set on the lower substrate glass and color filter is set on the upper substrate glass,control the rotation direction of liquid crystal molecules by changing the signal and voltage on TFT,So as to achieve the display purpose of controlling whether the polarized light of each pixel point emits or not.

  Now LCD has replaced CRT as the mainstream, and the price has dropped a lot and has been fully popularized.

(1)Which is better, lcd screen or tft screen?

  TFT(Thin Film Transistor) is a kind of LCD screen,It means that each liquid crystal pixel on the LCD is driven by a thin film transistor integrated behind it.Thus, screen information can be displayed at high speed, high brightness and high contrast.

  One DOT point=three RGB pixels.

At present, most of the TN panels we see are improved TN+film,Film is the compensation film,It is used to make up for the shortage of TN panel visual angle,At present, the viewing angle of the improved TN panel has reached 160 °,Of course, this is the limit value measured by the manufacturer when the contrast ratio is

  At present, most of the TN panels we see are improved TN+film,Film is the compensation film,It is used to make up for the shortage of TN panel visual angle,At present, the viewing angle of the improved TN panel has reached 160 °,Of course, this is the limit value measured by the manufacturer when the contrast ratio is 10:1,In fact, when the contrast drops to 100:1, the image is distorted or even biased.

  The color screens of mobile phones vary depending on LCD quality and R&D technology,The types are STN (CSTN), TFT (LTPS), TFD, UFB and OLED.

(2)Differences between TFT and LCD　

  LCD(Liquid Crystal Display),It is generally divided into monochrome and color LCD screens,At present, monochrome LCD has almost exited the notebook computer market,the color LCD market continues to develop.Color LCD is mainly divided into STN and TFT,TFT (Thin Film Transistor) LCD

is also known as active electrocrystalline thin film transistor liquid crystal display,It is also called true color LCD by many people.DSTN (Dual-Scn Twisted Nematic)LCD,It's called dual scan LCD.It is a display mode of STN LCD and has been withdrawn from the market.

  I believe you have a general understanding and cognition of TFT and LCD,LCD refers to liquid crystal display, TFT is a kind of LCD.The former is dedicated to laptops, while the latter is dedicated to desktop computers.LCD has several different technologies,FED,PDP,OLED,TFT-LCD,All belong to LCD.However, desktop computers use the first few more, and the cost is low,TFT technology costs a lot and is generally used in laptops or Auto car etc.Now most of the displays are TFT type displays.I believe that you will find it in the selection and purchase of digital goods in the future.
