What's the difference between LCD screens and OLED screens?

Mobile phone screens are mainly divided into LCD and OLED screens. The most fundamental difference between them is that LCD needs a backlight to emit light. The oled screen is self-luminous. It is precisely because of this difference that they differ in display.

For example, if the display is also green, it is obvious that the oled color is more intense. LCD has a backlight layer. It is inevitable that there will be losses in brightness and color. The display including black is not pure black. The oled screen is characterized by self-illumination. Use very thin, organic material coating and glass substrate. The screen is thinner and the color gamut is wide. The colors are also very vivid and visually more pleasing. But too bright colors can easily cause visual fatigue. oled screen method of controlling brightness. It is the constant switching of pixels. That is, pwm dimming. In low brightness, such as using mobile phones at night, there will be flickering. It is this kind of black that faces such a screen for a long time that will make some people with sensitive eyes feel uncomfortable.

In contrast, LCD screens are much better. However, some manufacturers will also equip the OLED screen with DC dimming to solve the review problem. So everyone is choosing OLED screen to see if there is DC dimming? Or turn on the lights when playing on the phone at night. oled works independently because of pixels. More power saving but because the working time of each pixel is different. A long time will easily lead to uneven screen aging. That is, the flask is also the Achilles heel of the OLED screen. Of course, there is no problem in normal use for 3 to 4 years.

No matter what color the LCD screen displays, the backlight is fully turned on. So the corresponding will consume more power but as long as the screen is not damaged. There will be no obvious color cast. There is no burn-in phenomenon. In fact, through the comparison just now, what I want to say is. Whether it is LCD or OLED screen. They all have their own advantages and disadvantages. But now it is obvious that high-end mobile phones basically use OLED screens. Many mid-range machines, even thousands of yuan machines, have begun to carry oled screens. Do you think the OLED screen will replace the LCD screen? Welcome to leave a message in the comment area.
