OLED technology in Taiwan falls behind Korea for three years

LCDs can be seen everywhere in life and are currently the main display technology for mobile display devices. However, it is a perspective problem criticized by people and it is also one of the challenges that manufacturers want to solve. Because the viewing angle of the liquid crystal display is small, the screen will be distorted when the viewing angle is too large, and the contrast and color performance are also poor, so the panel maker has developed a wide viewing angle technology. The wide viewing angle technology not only directly relates to the viewing angle of the liquid crystal display, but also affects the response time, brightness, and the like of the liquid crystal panel.

Of course, AMOLED will not have the problem of perspective. However, Taiwan’s technology still lags behind South Korea for three years and will need to catch up in the future. Wide viewing angle technology is common TN panel, VA panel, IPS panel and FFS panel extended by IPS technology, in which VA panel is divided into MVA panel led by Fujitsu, PVA panel developed by Samsung and CPA panel developed by Sharp. The leading technology vendors include Hitachi's LG Display, Samsung's PVA, Fujitsu's MVA (AUO and Chi Mei), Sharp's CPA (ASV), and Yuantai's South Korea's Hydis' FFS.




AMOLED Panel DisplaySearch stated that in order to meet the demand for high-performance screens such as wide viewing angles, high contrast, and low color shifts in smart phones and tablet PCs, the development of two wide-view technologies, such as IPS and FFS, is currently expected to be the most promising. Volume will grow from 214 million tablets in 2010 to 600 million tablets in 2014. According to Xie Qinyi, vice president of DisplaySearch, in the past, panel makers such as AUO, Chi Mei, and Samsung all belonged to the VA wide viewing angle camp. However, it will be inevitable that all panel makers will face cross-platform in the future, that is, those who have invested in the VA camp in the future. It is also possible to develop both IPS and FFS technologies.

As for the original focus on the IPS camp industry, including Hitachi, Lucky Gold Display (LGD), and FTS's Yuan Tai, is expected to take advantage of the fisherman. It is understood that Yuantai has changed many of the company's old production lines to FFS products. This has enabled Yuantex's FFS-only franchise and products to reach 40% of its revenue, and it has also become the main driving force for growth.

In addition, according to the Nihon Keizai Shimbun, Hon Hai is actively involved in the capital increase of Hitachi Display Corp. and plans to acquire more than half of Hitachi’s Hitachi displays for up to 100 billion yen (approximately NT$36 billion) in the next 2 years. Equity. Industry pointed out that Hon Hai’s Chi Mei and HITACHI signed the IPS cooperation agreement for wide-angle LCD panel technology. If Hon Hai further acquires Hitachi Display’s equity, Apple’s “Double i” panel order and “Anti-Korean” business will take place. At the same time, you will be able to use the magical effect of a double-edged sword.

Of course, the main reason for the development of a wide viewing angle panel is that the liquid crystal display must use two layers of color filters to cause the problem of too small a viewing angle. This kind of problem, in fact, can be self-luminous panels, such as PMOLED or AMOLED display will not happen. However, after Taiwan's panel makers entered the OLED display industry two times, they are now back to catch up with South Korean manufacturer Samsung. The pace is already too late. Experts believe that the current technology of Taiwanese manufacturers is about three to four years behind South Korea. In the future, it is necessary to catch up with the progress of Samsung's AMOLED technology development. In terms of resolution and large size, they have to step up their efforts and have the opportunity to catch up.
