1、 Different categories1. TFT screen(1) TFT-LCD is a kind of thin film transistor LCD, which is also called "true color" (TFT);(2) Ufb, ufb is a display specially designed for mobile phones and PDAs;(3) STN screen, also known as super twisted nematic LCD screen2. LED screen(1) According to the use environment, it can be divided into indoor, outdoor and semi outdoor;(2) According to the color, it can be divided into single color, double primary color and three primary color;(3) According to the control or use mode, it can be divided into synchronous and asynchronous;(4) According to the display performance, it can be divided into video display, text display, graphic display and quotation display;(5) According to the display device, it can be divided into LED digital display, LED dot matrix graphic display and LED video display2、 Different application places1. TFT screen: it is one of the LCD screens.

The difference between TFT and LED screen

for example, LCD TV, LCD computer display, mobile phone display, etc.
TFT screen is one of the LCD screens2. LED screen: used for LED display in sports venues and outside shopping mallsExtended information:1、 Advantages1. LED screenThe screen is ultra-thin and light-emitting on the side.
the whole screen is illuminated by the light guide plate, and there is no delay in the instant lighting;The efficiency of LED is generally higher than 100 LM / W, and CCFL is about 60-90 LM / W;It has a long life2. TFT screenThe color is bright and true;The price is low;The uniformity of screen light is better;The technology is mature2、 Disadvantages1. LED screenThe color is not bright;The brightness is uneven2. TFT screenShort service life;The power consumption is slightly higher.
the fever is slightly higher.
the power consumption is slightly higherSource: Baidu Encyclopedia - TFT screenReference source: Baidu Encyclopedia - LED display screenThese are two different types of problems in the field of liquid crystal technology.
in the field of liquid crystal technology, there are two types of problemsFirst of all, TFT: TFT (thin film transistor) refers to thin film transistor.
it means that each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel.
it is an active driving mode now.
corresponding to the passive driving mode of black-and-white display in the early days.
now basically, TFT LCD is used for color screens with higher resolution.
in recent years, TFT LCD is widely usedBesides, LED backlight.
because liquid crystal display is a non active light-emitting display technology, that is to say, the liquid crystal panel is just a light switch, It controls the switch of each pixel to display the image.
behind the light switch, an area light source is needed to emit light.
this area light source is called backlight.
there are generally two kinds of backlight light sources.
one is FCCL (cold cathode tube) and LED (light emitting diode).
and the LED backlight is the light source of LED. they can coexist. Nowadays, most of the displays are LED backlight and TFT panel.
these two concepts are different from each otherAs for LCD.
it should be a clerical error upstairs. If you want to write FCCL, LCD is the abbreviation of liquid crystal display, which translates into Chinese as liquid crystal display.
in Chinese, LCD is the abbreviation of liquid crystal displayAs for the difference between LED and FCCL.
from the general trend, LED has more advantages, and it is likely to replace FCCL, mainly for thinner design.
there is not much difference in energy consumption in other life.
FCCL only needs higher voltage.
LED needs lower voltage.
FCCL needs lower voltageBut in terms of luminous efficiency,
there is little difference.
but FCCL is a lamp tube.
there is mercury vapor inside, which is a bit like fluorescent lamp tube (there are still some differences), which is not very environmental friendly, and the design is difficult to thin.
the design of FCCL is simple and convenientFor ordinary users,
the LED is thinner.
more fashionable.
for ordinary users, the LED is thinner
