Which material of mobile phone screen is the best?

With the rapid development of the times, smartphones have spread all over the world. However, among all the parts of a smartphone, the one we touch most should be the screen. Sometimes the quality of the screen is the main condition that determines whether we buy or not, so many of our mobile phone friends will take the screen size as the first choice when buying a mobile phone. But only care about the size or resolution of the mobile phone screen, and don't care about the quality of the screen material, this is a big misunderstanding when buying. You should know that the quality of a mobile phone's screen is related to many factors, such as screen material and bonding technology.
 

 
The material types of the mobile phone screen include LCD, TFT, IPS, OLED, and AMOLED.  
 
However, which material of mobile phone is better? Let KTBABA tell you how to distinguish mobile phone screen materials: LCD, TFT, IPS, OLED, AMOLED.
 
The full name of LCD is liquid crystal display, which is the most widely used mobile phone screen material. It is characterized by low price and widespread use. It needs backlight support when displaying.
 
In the main screen material of the mobile phone parameter table, some letter combinations such as TFT, IPS, SLCD, UFB, SNT, NOVA, etc. are often seen. They do not represent different screen materials, but different display technologies of LCD. The most common LCD technologies in mobile phone screens mainly include TFT, IPS, SLCD, and other screen materials:
 

LCD Display
 
The LCD screen is composed of a backlight, a lower polarizing plate, a driving layer, a liquid crystal layer, a color filter, and an upper polarizing plate. Among them, the driving layer is composed of thin-film transistors (TFT), so the term TFT-LCD is often seen.
 
TFT Display
TFT (Thin Film Transistor) is a thin-film field-effect transistor, which is a type of active-matrix liquid crystal display.
 
The TFT liquid crystal display is characterized by good brightness, high contrast, strong layering, and bright colors, but it also has the disadvantages of relative power consumption and high cost.
 

For example, the famous JDI screen is a TFT-LCD display, which uses LTPS low-temperature polysilicon technology screen. Compared with traditional LCD screens, JDI screens are thinner and more transparent.
Many representative models are using JDI screens, such as Huawei mate10 and Nubia Red Devils gaming phone.
 
IPS Display
IPS, commonly known as "Super TFT", is a technology upgraded from TFT. The essence is still a TFT screen, but a TFT screen using IPS technology. Compared with the ordinary TFT screen, it has the advantages of a large viewing angle, accurate color reproduction, no watermark on the touch, environmental protection, and power saving.
 

The representative model is the iPhone. For a long time, the iPhone has used an IPS screen. The best quality IPS screen is basically bought by Apple every year. Compared with Android phones of the same price, the iPhone uses an IPS screen, even if the resolution is lower. , The look and feel of the screen can still be maintained to the top level. But starting with iPhone X, Apple mobile phones have begun to use AMOLED screens.

But starting with iPhone X, Apple mobile phones have begun to use AMOLED screens.
 
SLCD Display
SLCD is a special LCD screen for splicing. It is a high-end and advanced variety of LCDs. It is characterized by warmer colors, realism, is more natural, and is suitable for human eyes.

At present, HTC mobile phones use the most SLCD screens.
OLED
OLED (Organic Light-Emitting Diode) refers to organic light-emitting diodes. OLED does not require backlight support, has self-luminescence, and has the advantages of wide viewing angle, high contrast, low power consumption, high response rate, full color, and simple manufacturing process.
According to the driving method, OLED can be divided into passive OLED (PMOLED) and active OLED (AMOLED).
 
AMOLED screen
 
AMOLED screens have the characteristics of bendable, wide color gamut, display colors are more vivid, and have the advantages of self-luminous and low power consumption, and have become a hot choice for mainstream high-end mobile phones.
In the field of AMOLED displays, SS and LG can be said to dominate the world, with a market share of more than 90%, so the best AMOLED screen phones are of course SS’s latest flagship phones, such as SS Note9, S9, Xiaomi 8, OPPO Find X, Vivo Nex, Meizu 16, Apple iPhone X, etc.


According to the driving method, OLED can be divided into passive OLED (PMOLED) and active OLED (AMOLED).
 
In short, if you want to choose a good screen, look for AMOLED and IPS screens, especially AMOLED. Most high-end flagship phones use AMOLED screens.
 
In addition to paying attention to the screen material and resolution, we also need to care about the screen's full bonding technology and packaging technology, and other parameters.
