Panel display technology diversification, LCD is still the mainstream

2021.09.15

In recent years, the color TV industry continues to emerge new panel display technology and accelerate the iteration, for the industry set off round after round of climax. In this regard, Dong Min, general manager of black electricity division of AVC, said that the display technology "flowers bloom", to a certain extent, can create better user experience, promote the rapid development of the industry.

From full HD to ultra HD display technology, from "flat" to unique curved surface display technology, LCD liquid crystal technology has shown a strong vitality. In 2013, when UHD was in its infancy, only about 900,000 units were sold in mainland China. After entering 2014, the screen factory seized the development opportunity, comprehensively upgraded the resolution of LCD TV, and large-scale 4K market; In order to further improve the picture quality, the screen factory even introduced 8K display panel, the overall layout of the ultra HD display field. For now, 2014 is expected to be a breakout year for UHD, as 4K TVS become increasingly available in a variety of sizes and features, and become more affordable. According to AVC, 13.9 million UHD panels are expected to be shipped to the Chinese mainland in 2014, and UHD terminal sales are expected to exceed 10 million units.

Since SONY was the first to release curved LCD TV in 2013 and brought it into public view, many companies have launched new curved TV products. Although 4K is the mainstream at present, there are still limitations of live broadcasting and content, so that consumers may not feel obvious differences; In addition, the current LCD curved TV is only the change of physical form, which does not involve a great technological leap. At present, the main first-line panel manufacturers are capable of introducing curved modules, or supply the Open Cell that can be bent to the whole machine manufacturer, and then the whole machine manufacturer will produce curved LCD TV at the system end. Therefore, it will be a good marketing point to promote "curved TV" as a new trend.

Dong Min stressed that the size of the future development space of curved TV is not focused on technology, production capacity, or even cost, but need to be verified by the market and consumer acceptance. In addition, considering the low yield and high price of curved screen, it still takes time to improve the display Angle of view and the sense of presence, "it is expected that the development prospect of curved TV remains to be seen".

OLED was once recognized as the "next generation display technology", but its current development is limited due to immature technology and low yield. Although some screen manufacturers, such as SDC, hold a conservative attitude towards OLED, there are still some manufacturers, such as LGD, who are full of confidence in OLED. They not only actively layout in production line planning and product planning, but also improve the yield from 40% to about 70% through technical improvement. At PRESENT, due to the influence of key technologies, costs and other factors, the large-scale application of panels and large-scale industrialization still have a long way to go. According to AVC, global OLED panel shipments will reach 200,000 in 2014. In the next 2-3 years, OLED technology will be in parallel with TFT-LCD technology, with a turning point in 2017. However, OLED will not replace LCD TV in the short term.

Although the laser cold screen display appears after the LCD and OLED, but it has the advantages of the screen is not dazzling, the picture quality is clearer, the same size price is lower, the TV is more energy saving, long service life and so on, it also shows strong vitality. With further advance of industrialization, technology and the market matures, lower cost price, especially the lower cost of laser, laser TV in big venues utility ratio will rise sharply, general will shorten the period of time in the family, is expected to take five to 10 years, will form a challenge to the current LCD industry.
