What is the difference between LED and OLED?

9. The liquid crystal panel emits light through the backlight, and various colors are produced by the refraction of the liquid crystal molecules. The liquid crystal molecules cannot emit light by themselves, and the LED refers to the backlight, while the OLED itself can emit light without the need for a backlight.

10. LEDs use metal materials, while OLEDs use organic materials

11. More advanced, it can emit light independently without lighting, and the contrast is relatively good, and the LED that is usually used needs to be illuminated by a back light to see things.

12. The screen made by OLED is lighter and thinner than LED, shock resistance, wide viewing angle, not easy to heat up, and high luminous efficiency, while LED is hardly used on TV display screens at present.

From the current point of view, LED screen is still the mainstream of the market, it has the characteristics of "longevity" and "cheap". OLED can be regarded as a next-generation screen, with better and excellent picture quality advantages, it can also achieve curling, transparent, folding, extremely thin and light design, and has a faster response speed, which is more in line with future display scenarios. All aspects have matured and have begun to have the foundation for a large-scale outbreak. 22.02.16

As the next-generation display technology, OLED 1.3 display technology will be widely used in smartphones, VR, wearable devices, TVs, tablet computers, smart cars, etc., and the overall market prospect is broad. According to relevant data, it is predicted that the global OLED shipments will reach 900 million units in 2020, which will be 2.5 times that of 2015, with a compound annual growth rate of 20%. In addition, as BOE, CSOT and other manufacturers seize the commanding heights of the OLED market, the pace of the domestic display industry to break through the monopoly of Japanese and Korean companies has been accelerated. Some analysts predict that global OLED smartphone panel shipments will reach 1.37 billion units in 2019, and will surpass LCD panel shipments for the first time in 2020, becoming the mainstream of the market.

The technical principles of OLED and LED are far more complicated than the introduction, here is just a quick introduction to the difference between the two. From an experience point of view, OLED screens are obviously more advantageous than LEDs, but the current price is expensive, the lifespan is relatively short, and the penetration rate is relatively low. It is believed that in the future, with the decline of technology and cost, the prospects will be broader, and it is only a matter of time before LED is surpassed, but there will still be a long way to go to completely replace LED.
