The problem with OLEDs is not only the yield
Not long ago, some media reported that Hisense would push OLED TVs next year to prove that Hisense had misjudged the direction of the next-generation TV development.
actually not. Regarding the attitude of Hisense to OLED, the outside world has always been misunderstood. As the top three color TV giants in the world, it is believed that Hisense will seriously study every color TV technology and will not simply use “support†or “oppose†to vote.
Hisense's true attitude toward OLEDs is that Hisense never excludes OLEDs. However, based on the deficiencies of OLED technology and its own reserves and judgments on next-generation TV technology, it will not bet OLEDs like some companies. Hisense CEO Liu Hongxin once said that as long as the technology is mature and consumers accept, Hisense is also likely to push OLED TV.
Hisense's attitude is actually very sincere and pragmatic, but for the OLED camp, the lack of the unconditional strength of Hisense, the world's top three giants, is not so optimistic about OLED's prospects.
Why aren’t Samsung and Hisense, the two largest color TV giants, do not have OLED platforms, but have led the development of display technologies such as quantum dots, ULEDs, and laser televisions? In the eyes of the outside world, the big screen yield problem of OLED is the biggest reason, but in my opinion, the yield problem is just one of the reasons.
First of all, at present, OLEDs rarely support 4K and 8K panels, and LCDs have already matured in this area. With the popularity of 4K sources, the disadvantage of OLEDs will become more prominent.
Second, compared to ULED, quantum dot TV, laser TV, OLED TV prices are too high. Especially support 4K OLED, its price far exceeds LCD TV and laser TV. For example, LG Signature OLED TVs, 65-inch in the United States sell for 7999.99 US dollars (approximately 53,400 yuan), 77 inches of 19999.99 US dollars (approximately 133,400,000 yuan), the domestic price of these two TVs is about 6 Ten thousand yuan and 150,000 yuan. This price is 6-7 times that of Hisense 4K ULED products.
Once again, the problem of OLED burning has not been solved well at present, and it is equally difficult to avoid OLEDs that were affected by plasma. With such shortcomings as residual images and aging, OLEDs are still unable to come up with a complete solution, while LCD technology and laser TV technology do not need to worry about this.
Of course, we must mention that although BOE has begun to layout OLED, but in fact this technology is more in the hands of foreign companies, LCD TV companies experience the "core lack of screen" pain, in the next TV era Before taking the initiative to evade, domestic companies such as Hisense must seriously consider.
To sum up, the issue of OLED yield is not the only issue that restricts the development of OLEDs. The multiple constraints of technology, price, and dominant power are all important reasons why OLEDs can't open up. It is also difficult to solve these problems in a short time, Samsung, Hisense chose to wait and see, and vigorously develop their own leading next-generation television technology.
Three standards for next-generation television
If OLED can not represent the direction of the next generation of television, then who can truly represent the future? From the current perspective, quantum dots and laser television are the two main options.
The author believes that although quantum dots have many advantages, they are technically very difficult to achieve electroluminescence and can only achieve photoluminescence, that is to say, they are still the upgrade of liquid crystals or the refurbishment of OLEDs, so if you use Quantum-dot TV is not the best option for measuring next-generation television technology.
To truly represent the next generation of television technology, I believe that at least the following three conditions must be met: First of all, to escape the scope of LCD, LCD TV can not be an extension of innovation. Second, we must avoid the major technical defects of OLED and LCD. Again, it is necessary to have a cost-price advantage that is suitable for rapid adoption. As far as the current situation is concerned, laser TVs will undoubtedly be the first choice for next-generation television technology.
First of all, laser televisions have better picture quality than those of liquid crystals and OLEDs. They are also healthier and more eye-safe. Compared to traditional projections, laser televisions have bright colors and high brightness. The gamut coverage of laser televisions can theoretically be as high as 90% of the human gamut. In terms of picture quality, it can make the entire TV picture look more realistic, with a sense of depth and transparency. At present, Hisense has brought laser television to the high-definition 4K era.
Compared with LCD TVs and OLED TVs, laser TVs have larger and more flexible screens and are not affected by the directionality of viewing angles, allowing users to enjoy excellent screen effects from all angles. At the same time, the bionic optimization of laser television shows that it adopts the principle of reflection imaging to avoid the damage of direct light and can be close to the eye and not hurt the eyes.
Second, the manufacturing cost of laser televisions is more advantageous than liquid crystals and OLEDs. Laser televisions are mainly lasers. After optical signals are processed, light images are used to form images. This can basically remove the traditional related components, save some optical devices, the cost savings is 30% -40%.
Compared with LED LCD TVs and OLED TVs of the same size, the lifespan of laser TV light sources is longer and can reach more than 100,000 hours. The product price is much lower than that of LCD TVs and OLED TVs. For example, Hisense 100-inch 4k laser TV sells for 79999 yuan, while the same size OLED TV sells for 1 million yuan.
Thirdly, laser television is basically independent research and development. Compared with liquid crystals and OLEDs, it has advantages in industrial development initiatives. In the era of flat-panel TVs, panels and chips are the key to the transformation of China's color TV brands from big to strong. The lack of core autonomous technologies has caused Chinese TV companies to suffer a lot of losses. To innovate in the extension of LCD, or follow the development of OLED giants abroad, it is likely to repeat the old era of flat TV China TV companies.
learn from mistakes. In the era of flat-panel TVs, 3S (Sony, Samsung, Sharp) had dominated the development of the color TV industry and gained high profits. China's color TV companies can only be in the downstream of the industrial chain, and more terminal assembly work, it is difficult to have the right to speak. At present, Hisense's independently researched and developed laser television and laser optical engine can be 100% independent R&D and design, and completely independent operation from R&D and design to complete machine manufacturing. More than 70% of manufacturing costs are in their own hands.
The choice is greater than the effort and the direction is wrong. The result can only be the north and the south. Leading technology, controllable costs, and independent research and development depend on these three points, and laser television should lead the next television era.
