Phone is good, the screen is the first thing you see, good or bad phone screen is directly related to the operation and visual effects. But to know the phone screen requires a lot of expertise, there is no background knowledge of most people simply do not understand, speak up and very complex. Here, the professor with the most simple words, along with further analysis of the basic knowledge and everyone’s phone screen.
Look at the phone screen parameters, in addition to look beyond the resolution and screen size, the phone screen depends on the material, which is affecting the screen color performance and degree of detail is more important. Depending on the material, cell phone screen can be divided into LCD (liquid crystal display) and OLED (organic light emitting diode) two categories.
1, LCD (liquid crystal display)
LCD (Liquid Crystal Display) stands for liquid crystal displays, is now using more mobile phone screen material, characterized by cheap, widely available, when the display needs the support of the backlight.
In the main phone screen material parameter list this one, we often see TFT, IPS, SLCD, UFB, SNT, NOVA and some letter combinations. Strictly speaking, they are not representative of different screen material, but different LCD display technology. The most common cell phone screen LCD display technology are mainly the following:
TFT (Thin Film Transistor) that is thin-film transistor, active matrix liquid crystal display part in one.
TFT LCD screen is characterized by good brightness, high contrast, strong sense of hierarchy, bright colors, but there are relatively high cost and lack of power.
IPS commonly known as “Super TFT”, from the name to know, IPS is a technology upgrade from the TFT, its essence or TFT screen, just use IPS technology TFT screen. Compared to ordinary TFT screen, it has a large viewing angle, accurate color reproduction, touch no watermarks, environmental protection and energy saving advantages.
SLCD Splice Liquid Crystal Display is the English acronym, that splicing dedicated LCD screen, it is a high-end LCD derivatives, which is characterized by warmer colors and more natural for the human eye.
2, OLED (organic light emitting diode)
OLED (Organic Light-Emitting Diode) refers to the organic light emitting diode, OLED backlight without support, with self-luminescence, also has a wide viewing angle, high contrast, low power consumption, high reaction rates and full-color, process simple.
According to the driving mode to divide, OLED can be divided into passive OLED (PMOLED) and active OLED (AMOLED)
Currently used to make phone screen OLED basically AMOLED, which is widely used in mobile phones, the TV screen. AMOLED self-luminescent, low power consumption, wide viewing angle, high contrast and high response rate advantage, but difficult to see in direct sunlight, reading relatively poor.
Super AMOLED screen
Super AMOLED is an improved version of the AMOLED screen is a lot of use on Samsung mobile phones, but in fact it is not Samsung’s exclusive technology. Super AMOLED very controversial, on the one hand it is more sensitive than AMOLED operation, not only can see the screen in the sun, you can also see from any angle and fast response. But the disadvantages are also obvious, the biggest drawback is the reduction of the color difference, bright colors unreal.
Talk so much, the most important thing we have to remember is that the phone screen is only two kinds of LCD and OLED, TFT, IPS, SLCD screen display technology, etc. are. Second, different materials and different display technologies and there is no absolute good or bad points, their biggest difference is that there are differences of color reproduction, there are different power consumption.
