The obvious advantages of OLED over LED screens are better display effects, brighter colors, higher contrast, wider viewing angles, lower energy consumption, better lightness, flexibility, and faster response speed.
The obvious advantages of OLED over LED screens are mainly reflected in the following aspects:
1. Better display effects:
- Brighter colors: Since OLED screens are organic light-emitting diodes, each pixel can emit light by itself, and the color purity is higher, which can present richer color levels and brighter pictures. In contrast, LED screens require backlight sources, and the color performance is relatively bland.
- Higher contrast: OLED screens can achieve true black, because when the pixels are not emitting light, the screen is completely black without any light overflow. This makes the OLED screen extremely high in contrast when displaying dark pictures, and the picture is deeper and more three-dimensional.
- Wider viewing angle: The viewing angle range of OLED screens is very wide, and consistent color and brightness can be maintained from almost any angle without color shift or brightness drop.
2. Lower energy consumption:
- OLED screens have the characteristics of self-luminescence, which means that only pixels that need to display content will emit light, while other pixels remain off, greatly reducing energy consumption. In contrast, LED screens need to continuously provide backlight for the entire screen, and the backlight continues to work even when displaying black or dark images, resulting in higher energy consumption.
3. Better lightness and thinness:
- Since OLED screens do not require backlight and complex backlight modules, their structure is simpler and can achieve thinner designs. This makes OLED screens more advantageous in portable devices such as smartphones, tablets, etc., and can provide users with a thinner and more fashionable appearance.
4. Bendability:
- OLED screens also have good bendability, which means that they can be designed into various shapes and curves, providing device manufacturers with more design possibilities. In contrast, LED screens cannot achieve this bendability.
5. Faster response speed:
- The response speed of OLED screens is very fast, with almost no delay or smearing, which makes it smoother and more natural when displaying dynamic images. LED screens, however, require structures such as backlight modules and liquid crystal layers, so their response speed is relatively slow.
In summary, OLED screens have obvious advantages over LED screens in terms of display effect, energy consumption, thinness, bendability, and response speed. However, OLED screens also have some disadvantages, such as high cost and relatively short lifespan. Users need to weigh their actual needs and budget when choosing.
