. It is a display tool that outputs specific electronic information to the screen and then reflects it to the human eye. The common ones are CRT display, LCD LCD, LED dot matrix display and OLED display.

A CRT display is a display that uses a cathode ray tube (Cathode Ray Tube). It is mainly composed of five parts: an electron gun, a deflection coil, a shadow cover, a phosphor layer and a glass shell. Although CRT flat panel display has many advantages, such as large visual angle, no bad points, high color restoration, uniform chromaticity, withered multi-resolution mode, short response time and so on, it has withdrawn from the market. CRT display is the earliest, the old TV used to be CRT display.

LCD (Liquid Crystal Display) display, or liquid crystal display. Compared with the previous generation of CRT displays (cathode ray tube displays), LCD displays have the advantages of low power consumption, small size, large amount of information and not harmful to the eyes, so it has become the mainstream electronic display equipment, including televisions, computer monitors, mobile phone screens and various embedded devices.

There are many liquid crystal particles inside the LCD display. They are regularly arranged into certain shapes, and each side of them has a different color, which is divided into red, green and blue. These three primary colors can be restored to any other color. When the display receives the display data, it controls each liquid crystal particle to rotate to a different color face, thus combining into different colors and images. Because of this, the disadvantages of LCD display are that the color is not bright enough and the visual angle is not enough.

TFT screen is the abbreviation of Thin Film Transistor (thin film transistor) and one of the active matrix type liquid crystal display (AM-LCD). TFT sets a special light tube on the back of the liquid crystal, which can “actively” control each independent pixel on the screen, which is the origin of the so-called active matrix TFT (active matrix TFT), which can greatly improve the reaction time. In general, the reaction time of TFT is about 80ms, while that of STN is that 200ms will flicker if you want to improve it. And because TFT is an active matrix LCD can make the arrangement of liquid crystals memorable and will not return to its original state immediately after the current disappears. TFT also improves the blurring phenomenon that STN will flicker (water ripple), which effectively improves the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, restoration ability and higher contrast, but the disadvantage is that it consumes more power and costs more.

IPS screen is a technology based on TFT, and its essence is TFT screen. IPS screen (In-Plane Switching, plane conversion) technology is a liquid crystal panel technology launched by Hitachi in 2001, commonly known as “Super TFT”.

TFD screen is the abbreviation of Thin Film Diode (thin Film Diode). Due to the power consumption and high cost of TFT, which undoubtedly increases the availability and cost of mobile phones, TFD technology was developed by Seiko Epson, a mobile screen giant, to be used exclusively on mobile screens. It is a compromise between TFT and STN, with better brightness and color saturation than STN, but more power-efficient than TFT. The key features of TFD are “high picture quality, ultra-low power consumption, miniaturization, dynamic image display ability and fast response time”. The display principle of TFD is that it is equipped with a separate diode as the control source for each pixel on the LCD. Because of this separate control design, each pixel will not influence each other, so the dynamic picture without residual shadow and bright colors can be displayed on the TFD screen. Like TFT, TFD is also an active matrix driver. The TFD originally developed can only display 4096 colors, but it can display the equivalent of 260,000 colors if image processing technology is used. However, it still lags behind TFT in color display.

UFB is the abbreviation of Ultra Fine & Bright. It is characterized by ultra-thin and high brightness. In the design, UFB also uses a special grating design, which can reduce the pixel spacing to obtain better image quality. Usually UFB LCD can display 65536 colors, can reach the resolution of 128×160 pixels, at the same time, the contrast of UFB is twice that of STN LCD screen, the brightness of 65536 colors is comparable to that of TFT display screen, while the power consumption is less than TFT display screen, and the price is similar to that of STN display screen, which can be said to combine the advantages of these two existing products. UFB LCD screen makes the multi-function mobile phone with super-large color LCD display closer and closer to us. However, there is still a certain gap between UFB and TFT, and the power consumption is not satisfactory.
