Recently, the most concerned OLED products are OLED TVs, which are recognized by the industry as the next generation display technology due to their scalability, large viewing angle and power saving. However, the high price is prohibitive.
In addition to some small-screen products, the well-known large-screen OLED products are OLED TVs launched by home appliance companies represented by LG. Can not help but ask, since OLED is the future display trend, and has many excellent characteristics, why OLED TV is slow to promote in China, and most home appliance companies are only customizing several OLED TV prototypes without energy production, the growth of this "role" What are the "difficult" places?
High price and low panel yield
Take the 55-inch TV as an example. At present, the LG 55-inch OLED TV is priced at 29,999 yuan in Jingdong Mall, while the LED TVs of mainstream domestic brands such as Hisense, Skyworth, TCL and the like are in the price of 4500-5000 yuan in Jingdong Mall. The price of OLED is about 6 times that of domestic LED TV, which will inevitably directly affect consumers' purchase of OLED TV, and naturally become the first obstacle to the promotion of OLED TV.
The yield rate is one of the important indicators to measure the maturity of the panel production line. Although the LG Display executives who master the right to speak on the OLED panel recently revealed that the “OLED panel yield is now close to 70%â€, the industry has no doubt about this number. Voice: "A year ago, the figure was only a dozen percent, and it was increased to 70% in one year. Unless it was a major technical difficulty during the period, the industry did not hear any relevant news."
The low yield rate directly leads to high cost of OLED TVs. The terminal consumer market is naturally rising, and most consumers still cannot accept high prices.
Technology is still immature, scale effect is not obvious
At present, OLEDs used in mobile phone displays can maintain 5,000 to 10,000 hours, while OLED TVs must maintain at least 30,000 to 50,000 hours. In addition, when using an OLED TV, image quality should not be a problem, the key is how long a high level of image quality can last. Such technical problems still need to be overcome, and OLEDs can make a qualitative leap.
With Sony and Panasonic announcing the exit of OLED research and development, the OLED camp is slimming down. The withdrawal of Sony and Panasonic does not mean that it is not optimistic about the future of OLED, but because OLED technology is too difficult, and the research and development of related technologies needs to be invested. Too much cost, which is undoubtedly unaffordable for companies that have been sluggish in their TV business.
Without the brainstorming of many companies, it is hard to imagine the difficulty of making breakthroughs in promotion by one or two companies alone. However, it is gratifying that in the future, Chinese enterprises will not be inferior in the field of OLED. The BOE 5.5-generation OLED panel line will be mass-produced, and the OLED line of Huaxing Optoelectronics is also actively exploring.
The industry believes that OLED is the future display technology direction that the industry is paying attention to. At present, it is subject to some key technologies, low cost and low yield. The scale application and large-scale industrialization of the panel still have a long process. In the next 2-3 years, OLED technology will be presented in parallel with the current mainstream TFT-LCD technology. In the short term, OLEDs cannot replace LCD TVs.
