Since the beginning of this year, a large number of companies and capital have flocked to the OLED field. From the upstream panel to the downstream machine, all aspects of OLED have shown explosive growth. Among the domestic manufacturers, Skyworth, Konka, and Changhong have all started mass production of 4K OLED organic televisions and launched a series of products. Among foreign manufacturers, LG Electronics, Panasonic, and Philips have also entered the OLED field.
In the display market, there are a lot of content that compares OLED and quantum dot TV. Whoever is better display technology has become the concern of the industry. It is understood that the quantum dot TV products currently on the market are not comparable to OLEDs because the technology products are still LCDs that require backlights for light emission. In principle, quantum dot films are only attached to the backlight of LCD components. Increasing the color gamut increases the cost and reduces the light transmission rate. In some colors, it is more natural to expand. Moreover, this quantum dot film is limited by the material temperature and has a limited range of applications. The OLED adopts a mature self-luminous OLED technology, which can control each pixel, so it has perfect black and accurate color performance, a wide viewing angle, and a vivid image quality without the backlight source.
QLEDs, the future quantum dot TV technology being developed, are more advanced, and QLEDs have similar lighting principles to those of OLEDs. However, the development process of QLED is complicated and huge, resulting in the formal commercial use of QLED TV still takes 4-5 years. The OLED display technology has entered the market for many years, and the technology has become more mature. At the same time, it has achieved remarkable results in terms of market performance and popularity.
The superiority of OLED is undoubted, but there are still doubtful voices. Afterimages, longevity, yield, and other issues are often mentioned. In fact, the "OLED bottleneck" mentioned in the current market has long been resolved. According to Lu Xiangde, president of LG Display's OLED Division, the lifespan of OLED products can now be guaranteed to be over 50,000 hours. If you watch 8 hours a day, you can use it for more than 17 years. In addition, the OLED panel has been completely resolved by the algorithm for improving the image quality and improving the characteristics of the components for the "ghost image" problem mentioned by the skeptics. At present, it is possible to ensure that 10,000 hours will not appear afterimages.
If we look at the yield rate, the initial yield of LCD panels is only less than 50%, and it only reaches 80% after 10 years; while 2K OLED panels have reached 80% of the yield in just two years. This speed of development is the inability of LCD panels. Catch up. Therefore, so-called OLED bottlenecks or defects have now been completely resolved, which also provides a huge impetus to the development of the OLED industry.
