I believe that we have a certain understanding of the LCD display, OLED display, but what is the difference between the two, today I came to give you a good science.
First of all to briefly understand the principle of screen display, in fact, no matter what equipment, as long as it is something with a screen, are made up of pixel points, and each pixel has three sub-pixels, that is, red, green and blue are the three primary colors in optical technology, and each screen has countless pixel points, each pixel point according to the ration, are able to display different colors, and ultimately all the pixel points on the composition of the screen we see.
Understand the principle of screen display, we understand the difference between these technologies later, there is a great help, but a screen want to display the picture, light pixel points is not enough, there must be light, but where does the light come from? I am here to distinguish between these screen display technologies.
LCD display
After the development of cell phones to the smartphone stage, LCD display (liquid crystal display) quickly dominated the mainstream, cheap, low power consumption, display color accuracy, basically does not stimulate the human eye, these advantages for the smartphone at the time, LCD display may be the optimal solution for use in the cell phone screen. But the LCD display has no way to self-illumination, want to display the screen, then, must rely on the backlight module, in the context of the technology at the time, want to make the phone into a full-screen, it is necessary to make efforts from the screen display technology, so our next protagonist also shines.
OLED display
OLED (organic light-emitting diode) was born, seems to be in the spirit of the LCD display to go, their biggest difference, determines the two display technologies, in the field of cell phone applications on the different, and LCD display need backlight module to provide light different, OLED does not need a backlight module, the display color is very vivid and good-looking, and can make the screen is very thin, and even can be bent.
But its shortcomings are also obvious, due to the pixel arrangement, OLED display pixel density, in the same size will be smaller than the LCD display, and because the OLED display uses organic materials, each pixel can work independently of the characteristics of its life, it will be shorter than the uniform deployment of the display effect of the LCD display, and a long time to display a more colorful scene, prone to the phenomenon of The phenomenon of screen burning.
Cell phone screens on the market now are basically LCD display or OLED display, want to distinguish between these two kinds of screen is also very simple, full-screen phone or equipped with screen fingerprints of the phone, basically use OLED display, and wider bezel, larger upper and lower chin of the phone, basically use theLCD displayOf course, based on the characteristics of the OLED display does not emit light, it does not emit light when displaying a black background, very pure and transparent, while the backlight module is still working when the LCD display shows black, there will be a slight source of light through, and the black is not pure enough.
Through the above introduction, I don't know if you have a clear understanding of the mainstream screen type now!
