The advantages of OLED screen compared with LCD screen

The first advantage:

The OLED screen can do Aways on display to remind you to turn off the screen.

When the phone locks the screen, it can light up some pixels individually to display some important information such as the time and notifications at low brightness and low refresh rate. Since the LCD screen is turned on, the entire backlight layer of the screen needs to be turned on, so this function cannot be realized with low power consumption.

The second advantage:

OLED screens have nearly infinite contrast.

Contrast refers to the brightness ratio of black and white to dark in the picture, and the higher the contrast, the more vivid the picture looks and the stronger the color. Low-contrast images look like watercolors, while high-contrast images look like oil paintings.

If the LCD wants to display pure black, the ideal state is that the liquid crystal molecules are completely closed, completely blocking the emitted backlight. However, the liquid crystal layer of LCD has a very fatal problem, that is, the deflection of the liquid crystal molecules can not be completely closed, so when the black is displayed, there will be fiber white light emitted, so what you see on this side of the screen is actually not pure black, but a greatly decreasing brightness.

The OLED screen is not the same, the OLED screen itself does not have a backlight, and each pixel can be independently controlled, so we can directly cut off the power supply to display black pixels, so that it can do not emit light at all, to achieve the true sense of pure black. Therefore, the contrast ratio of the OLED screen can be theoretically considered unlimited.

The third advantage:

Light leakage is also a very obvious advantage of OLED screens. 

The OLED screen itself does not have a backlight, each pixel is independently luminous, and the display of pure black is directly turned off, and naturally there is no possibility of light leakage.

Since the LCD screen has a backlight layer, and the screen panel is eventually installed on the phone or display, the backlight of the backlight layer is easy to leak out at the junction of the screen and the border. In the display of pure black picture, there will be a large area of halo phenomenon at the border, which is called light leakage.

The fourth advantage:

The OLED screen has a short response time.

The screen does not always display a static picture, if you want to display a dynamic picture, it means that each pixel needs to quickly switch colors, pixels from color to color all takes a certain amount of time, this time is the screen response time.

Too long the response time will lead to the dynamic screen display when the pixels are too late to change the color, resulting in the last picture has not completely disappeared, the next picture will be displayed, which will lead to residual shadows on the screen. LCD screen color switching is accomplished by controlling the deflection of the liquid crystal layer, so the speed of the liquid crystal layer deflection directly determines the gray response time of the LCD. The deflection of the liquid crystal layer is related to temperature, and the lower the temperature, the slower the deflection speed, which leads to the LCD screen at low temperatures will appear very obvious dragging phenomenon, which is very obvious on the mobile phone.

The OLED screen itself has no liquid crystal layer, and it is naturally not limited by the liquid crystal layer and temperature. The OLED screen is not without response time, the OLED screen in the color switch between the color response time is very short, almost impossible to have the phenomenon of shadow.

But when OLED screens switch from pure black to pure white, or from pure white to pure black, it takes much longer than other colors. OLED screens have a natural advantage in displaying dynamic images.

The fifth advantage:

OLED screen ultra-thin thickness, good ductility. 

The OLED screen has no backlight layer and no liquid crystal layer, so it can be made very thin. LCD is the backlight layer, the middle of the liquid crystal layer, and some polarizers, so the LCD thickness is much thicker than the OLED.

At the same time, OLED screen can be bent as much as paper, LCD due to the existence of backlight layer and liquid crystal layer, backlight layer and liquid crystal layer is a hard substrate, can only do a very small range of bending, which can only be seen on the desktop display such a large panel, mobile phone is certainly not possible. It can be bent, which means that it is easy to achieve a curved screen for the phone, which improves the texture of the phone itself.

The sixth advantage:

OLED screens consume less power.

LCD screen as long as you turn on the screen is the entire backlight is fully lit, so as long as the screen, no matter what is displayed is always consuming power. The OLED screen displays a pure white screen when the power consumption will be higher than LCD, but each pixel of the OLED screen is independently controlled brightness and switch, so that the brightness can be reduced or even turned off respectively.
