Introduction of LCD Display Types and Its Price Influencing Factors

There are many types of LCD displays. Generally, LCD displays can be divided into TFT, UFB, TFD, STN and other types. The following is an introduction to the characteristics of these types of LCD displays.

Ⅰ. TFT liquid crystal display

TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it.

Thereby, screen information can be displayed at high speed, high brightness and high contrast ratio. TFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy, and bright colors, but it also has the disadvantages of relatively power consumption and high cost.


Ⅱ. UFB LCD screen

UFB is an acronym for Ultra Fine Bright. It is Samsung's dedicated color display technology for mobile phones, which is characterized by ultra-thinness and high brightness.

UFB LCD screen makes the multi-function mobile phone with large color LCD screen closer to us. In general, UFB still has a certain gap compared with TFT, and the power consumption is not satisfactory.

Ⅲ. TFD LCD display

TFD (Thin Film Diode) UFB (UltraFine & Bcenter), TFD has better brightness and color saturation than STN, and saves energy than TFT.

Ⅳ. STN LCD display

STN (SuperTwistedNematic super twisted nematic screen), STN can only display 256 colors at first, and finally supports 4096 colors, even 65536 colors, it is more power-efficient and cheaper.

But you get what you pay for, and the STN LCD display is slow to respond. When playing moving images, it is easy to cause image retention, which affects the picture quality. In addition, color and brightness are fatal flaws, which are always worse than TFT.

Comprehensive expressiveness: TFT>TFD=UFB>STN resolution, comprehensive comparison is now the best LCD display tft.


Ⅴ. LCD liquid crystal display price factors

People often ask, how much is the LCD screen? Some people will compare prices everywhere on the Internet after asking the price, which is understandable.

In fact, this question is very simple. First of all, you need to clarify the quality, size, function, scene and other requirements of the LCD screen you want to purchase. Because for different purchasing needs, the selected LCD screen is different, and the price is naturally different.

1. Quality

At present, there are all kinds of lcd liquid crystal displays on the market. The same type of screen has several different quality grades. LCD displays on the market are often classified into ABC regulations and so on. The higher the grade, the better the quality and the higher the price.

2. Size

Size is also a basic factor that affects the price of LCD screens. The larger the size, the larger the material, the higher the cost, and the higher the price.

3. Function

The function of the lcd liquid crystal display determines the scene of the screen. The more functions, the stronger the usability, the wider the application, and the more applicable objects.

But the more functions it has, the more manpower, technology and capital the LCD Co., Ltd. needs to invest, the higher the research and development costs, and the higher the price.

4. Scene

LCD liquid crystal display is divided into industrial display, commercial LCD and medical display, etc. Different environments have different requirements for LCD screens.

Such as operating temperature, viewing angle, screen brightness and so on. For example, compared with indoor advertising LCD screens, outdoor advertising screens naturally require higher brightness and higher prices.

In addition, the factors that affect the price of lcd liquid crystal display are whether there is touch, and the prices of capacitive touch screen, resistive touch screen and infrared touch screen are different.

So it doesn't matter how much the LCD screen costs, what matters is where you use it, what functions you need to use, how long you use it, and how much you use it.
