Mobile users basically know how to understand the parameters of a cell phone. There are many concerns about CPU, running memory, space memory and so on. Do you pay attention to the screen of a cell phone when you buy your cell phone?
How much do you know about your mobile phone screen? The worst is Samsung?
Screen material classification
With the mobile phone color gradually popular, mobile phone screen material is becoming more and more important. The color screen of the mobile phone is different because of the different LCD quality and research and development technology. There are several kinds of TFT, TFD, UFB, STN and OLED.
We don't explain it in detail, even if there's not a lot of people in detail, right? Try to be simple, just know what mobile phones have used these screens and how it works.
TFT screen
TFT (Thin Film Transistor), a thin film field effect transistor (FET), is one of the active matrix liquid crystal displays.
It can actively control the individual pixels on the screen, which can greatly improve the response time.

The glory of HUAWEI's V9 is TFT (LTPS).
TFD screen
TFD (Thin Film Diode) is the abbreviation of the thin film diode. The TFD technology, developed by the Seiko and Epson Corp, is specially used on a mobile phone screen.
The features of TFD are high quality, ultra low power, miniaturization, dynamic image display and quick response time.

The Samsung SGH-D418's screen is the TFD screen.
UFB screen
The UFB (Ultra Fine & Bright) screen is a LCD display screen developed by Samsung in South Korea. It is characterized by ultra-thin and high brightness.
In design, the UFB screen uses a special grating design to reduce the pixel spacing to obtain better image quality. Usually the UFB screen can display 65536 colors and can reach the resolution of 128x160 pixels.

The Samsung SCH-X609's screen is the UFB screen.
STN screen
STN is the abbreviation of Super Twisted Nematic, the most exposed LCD, because the screen of the gray - scale mobile phone we used in the past is STN.
Aside from the gray scale STN, STN is now mainly divided into CSTN and DSTN.
It belongs to the passive matrix LCD device, so the power consumption is small and the power is saved, but it should be less than 200 milliseconds.
CSTN generally uses transmission mode lighting, must use external light source lighting, called backlight, lighting source should be installed behind LCD.

Panasonic X77 is a STN color screen; 128 pixels.
OLED screen
OLED (Organic Light Emitting Display) is an organic light emitting display, belonging to the new products in the mobile phone LCD, was praised as a dream display.
OLED display technology is different from traditional LCD display. No need for backlight, it uses very thin organic material coating and glass substrate. When organic electric current passes, these organic materials will shine.
And the OLED display screen can be lighter, thinner, more visible, and significantly less power consumption.
Although the better technology of OLED may replace the TFT and other LCD in the future, the organic light-emitting display technology has the disadvantages of short service life and large difficulty in the screen.
OLED can be divided into two kinds: passive driven PMOLED and active AMOLED.
AMOLED screen
Full name: Active Matrix/Organic Light Emitting Diode, which is colorized.
In terms of performance, AMOLED has a faster response, a higher contrast, and a wider perspective, which is a place where AMOLED is better than TFT LCD.
In addition, AMOLED has a self - luminescent feature and does not need to use a backlight board, so it is more thinner and cheaper than TFT.

OPPO R9s and OPPO R11 are all AMOLED screens.
One thing to note is that OPPO R11 Plus is not a AMOLED screen, but a TFT screen.
Super AMOLED screen
Full name: Super Active Matrix/Organic Light Emitting Diode) is a Samsung Corp developed a stunning screen, compared to the traditional AMOLED dazzle screen, abandoned before the touch sensitive layer + display layer architecture design, control is more sensitive.
In addition, the removal of the glass cover also brings a better display in the sun. At the same time, Super AMOLED also carries a mDNIe (mobile digital natural image engine) technology that can watch and react quickly from any angle.
It can be said that the Super AMOLED screen in the world is one of the most excellent phone screens well known to the public.

Vivo X9s and Samsung GALAXY S8 are all Super AMOLED screens.
It's worth noting that vivo X9s is a screen for 1080P, and Samsung GALAXY S8 is a 2K screen.
IPS hard screen
IPS screen (In-Plane Switching, graphic conversion) technology is the LCD technology company Hitachi launched in 2001, commonly known as Super TFT.
The IPS screen is a technology based on TFT, which is actually a TFT screen.
Hard screen technology is a more advanced LCD panel technology in the world.
Apple iPhone 4 and 4S using the IPS screen, of course it is still the basis on the Retina screen display technology, is a pixel split into four pixel display, the pixel density is increased by 4 times, reaching 326ppi, 300ppi people can see the resolution of 326ppi is that you can let you have look at the kind of paper products feeling when looking at the screen.
