The CES exhibition in January has come to an end, and the various novel products at the exhibition also broadened my horizons and gave me a lot of insight. On the surface, it is a feast for the eyes, but because this exhibition is not held in China, I have only seen these products in the photos, and have not experienced them in person. Affected by the epidemic, the 2020 China Home Appliances and Consumer Electronics Exhibition (AWE) originally scheduled to be held at the Shanghai New International Expo Center from March 11 to 14, 2020 will be postponed. But what is certain is that the manufacturers of these novelty products unveiled at the CES show in January will bring their black technology to AWE again, and there will even be some more “black” black technology.
Although this year’s AWE has been postponed due to the new crown epidemic, it does not prevent me from bringing you a preview of the Display technology of the AWE2020 exhibition, and you can also see the direction of technology development in the TV market this year. text.
Among these black technologies this year, the “dispute” between OLED and Micro LED should be the most concerned. In the CES exhibition, OLED technology has become a beautiful landscape. I’m excellent”, since everyone is an OLED player, I’m sorry, Samsung, Konka and other leaders have rubbed the big move (Micro LED), and the people who go to the exhibition can’t see the power of this big move, but this big move is for this An industry with a huge impact.
What is Micro LED? Why can it be used for big moves? In fact, in popular terms, it is the miniaturization and matrix technology of LED. A Micro LED Display product is basically composed of three blocks: TFT substrate, ultra-micro LED die, and driver IC. Thin-film, miniaturized, and arrayed LED backlights can make LED units smaller than 50 microns. Like OLEDs, each pixel can be individually customized and driven to emit light (self-luminescence). Micro LED not only inherits the characteristics of high efficiency, high brightness, high reliability and fast response time of inorganic LED, but also has the characteristics of self-illumination without backlight, small size, light and thin, and can easily achieve the effect of energy saving. Also because the manufacturing process of Micro LED is very difficult, it is used as a big move.
On February 5, LG Display announced that the large-size OLED panel has been awarded the “Low Blue Light Display” certification mark by the global safety certification body, UL (Underwriters Laboratories). LGD has obtained the “Low Blue Light Display” certification mark, which means that the blue light radiation of its display panel has reached the harmless standard stipulated by IEC. It is understood that LGD’s OLED panel is 50% lower than the IEC harmless standard (100W/sr/m2), which is equivalent to about 60% of the blue light radiation of LCD TVs with the same size and the highest configuration currently on the market.
In the dispute between OLED and Micro LED, it can be seen from different points of view. From a technical point of view, the gold content of Micro LED technology is indeed higher than that of OLED. better than ever.
From the perspective of future development, although OLEDs have mostly replaced LEDs, LED screens are no longer used on the newly released iPhone 11Pro, and OLED screen manufacturers have even passed the certification of eye protection screens, but the macro The emergence of OLED screens for viewing on the Internet may only be temporary, as better technology emerges.
Finally, let’s take a look at the difference between imagination and reality. The difficulty of OLED production is not as cumbersome as the production process of Micro LED. In the market, OLED has also lowered its price and increased production capacity. Many people can afford OLED, and even some manufacturers have appeared. situation in short supply. Micro LED does not have such a simple production process, and mass production is a problem, but the efforts of various manufacturers to research Micro LED indicate that in the future, Micro LED is likely to become a substitute for OLED .
In my opinion, the emergence of new technologies may be able to ban old technologies, but when new technologies are still in the growth stage and are not mature and stable, the old technologies are better. But to me, whether it is OLED or Micro LED, no matter how difficult it is to make, it is what the public needs to be able to sell it at a price that everyone can accept.
