What are the advantages of OLED screens for mobile phones? Technical analysis, worth collecting

Our mobile phone screen is composed of countless small dots, each of which displays its own color. So as long as these dots are small enough and the color they display can be controlled, a complete picture can be displayed. Each point can display three colors - red, green and blue, but this is only the "base color". Anyone who has been exposed to painting knows that we can actually create thousands of colors with just three background colors, so this is why we can see a variety of colors on our mobile phones.

What is the most essential difference between LCD screen and OLED screen?

The LCD screen mainly relies on the backlight layer,corning ces 2024 which is composed of a large number of white backlights. However, with only white as the "background color", other colors cannot be modulated, so a colored film is added to the backlight layer. The white light Color can be displayed through the film. However, in order to control the color of a local area, a layer of liquid crystal layer is added to change the voltage to control the ratio of color light. This is the essential working principle of the LCD screen.

The OLED screen is completely different. You can just make these countless small lights into a combination of colorful lights.oled panel manufacturers There is no backlight layer and liquid crystal layer of the LCD screen.

Advantages of OLED screens:

Thinner. The OLED screen only has countless small lights, no backlight layer and liquid crystal layer, and the thickness is greatly reduced. At the same time, it also means that mobile phone manufacturers can not only make the mobile phone thinner, but also stuff more components into it!

color. In fact, what we usually call contrast is the contrast between white and black, so the higher the contrast, the darker the picture. The LCD screen has a backlight layer and a liquid crystal layer, so the color cannot be pure black, while the OLED screen is almost pure black after turning off all the small lights!

Level of power consumption. The LCD screen has small colored lights, a backlight layer and a liquid crystal layer, etc. It has a lot of power-consuming materials, so it will definitely consume power faster! The OLED screen only has small colored lights, and the colored lights have nothing to do with power consumption!

Degree of bendability. Because the LCD screen has a backlight layer and a liquid crystal layer, it is destined to be unable to bend. The OLED screen can be bent like paper! Therefore, this is the reason why all folding screen mobile phones on the market now have OLED screens!

Disadvantages of LCD screens and OLED screens:

After talking about the advantages of each other, we must also talk about the disadvantages. The disadvantage of LCD screens is light leakage. In the past, many mobile phone users had light leakage around their hands. This is the biggest disadvantage of LCD screens! The shortcomings of OLED screens are equally obvious - screen burn-in! Screen burn-in means that an area or the entire screen of the mobile phone suddenly stops lighting up. In fact, it means that all the LED lights on the screen are broken, and the screen can only be replaced.

Therefore, since most mobile phones now use OLED screen phones, how should we use OLED screens correctly at this time? (That is, how to avoid screen burn-in?) In fact, the reason is very simple, that is, do not display the same content in the same area or full screen for a long time. This will greatly reduce the life of the OLED lights!
