What are the advantages of OLED screens? OLED display technology is different from traditional LCD display methods. It does not require a backlight. It uses very thin organic material coatings and glass substrates. When current flows through, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, with a larger viewing angle, and can significantly save power consumption.

Thickness: LCD is much thicker than OLED due to the existence of backlight layer and liquid crystal layer, so OLED screens are very easy to make mobile phones or displays thinner, which is a great improvement for mobile phones, and thinner screens allow you Insert more components to enhance the experience of other parts.

Flexibility: Because of the existence of the liquid crystal layer and the backlight layer, the LCD screen cannot be bent greatly, and the OLED can be folded almost like origami. Samsung's curved screen is supported by OLED technology. It should be noted that the curved screens on desktops are still LCDs. You can find that the degree of curvature is not large. OLEDs can be folded in half like paper.

What are the advantages of OLED screens

Color: Contrast refers to the ratio of white to black. The higher the contrast, the darker the picture. Because LCD has a backlight layer, black is not pure black, so the contrast is difficult to increase. OLED black does not emit light, so you can directly turn off the black area. Pixels, so that it is basically infinitely close to black.

Separate lighting: When LCD is turned on, the entire backlight layer is turned on, so LCD is either fully turned on or fully turned off, and each pixel of OLED is independent, so OLED can individually light up certain pixels, so that you can Screen reminders (aways on display), which can greatly reduce the number of times the screen is turned on and indirectly save power.

Power consumption: OLED, because the pixels work independently, should be bright, dark and dark, and off, no matter what color the LCD displays, the backlight is fully turned on, so LCD is destined to consume power.

Screen response time: The color of the screen is displayed by pixels, and it takes time to change the color of pixels. This time is called gray-scale response time. If the gray-scale response time is too long, afterimages will appear. Smear will appear visually, which greatly affects the visual perception. There is almost no procrastination on the OLED screen, while the smear is still a smear on the LCD screen.
