Recently, Apple's new iPhone model, which will be released in 2019, will have two OLED displays. Even if the iPhone X sales volume is not as expected, however, the OLED display trend of smart phones driven by Apple will inevitably affect the willingness of other brand mobile phone manufacturers to introduce OLED displays. WitsView predicts the wisdom of adopting OLED displays in 2021. Mobile phone penetration will reach 46%.
Dai Zhenjia, general manager of Taiwan's Nichia, said that Apple's smart phones use OLED displays, which have certain impacts and challenges on the LED market. However, LCD backlights and LCD panels are already quite mature technologies. Although the LCD monitors must have a 4 to 4.5 mm frame on the full screen of the smart phone, it is not possible that the OLED display can be almost borderless. Design, but LCD monitors and LED technology continue to evolve, will catch up with the leading distance of OLED displays.
In fact, Nichia's LCD backlight new product NTSV can further reduce the LCD display frame. Nichia's second department of technology chief 坂本考史 said that the company's latest LCD backlight technology NTSV has been able to make LCD display frame from the traditional 4 ~ 45. Mm, reduced to 2 ~ 2.5mm, quite close to the OLED display, and the picture quality is quite refined. In addition, since LCD backlights and LCD displays are mature technologies, they are also more advantageous than OLEDs in terms of cost. At present, a mobile phone manufacturing company has adopted the Nissan Chemicals NTSV LCD backlight product to develop new mobile phones.
Not only that, LCD monitors have an absolute lead in 4K, 8K, and even 10K quality displays. Dai Zhenjia explained that LCD TVs can now achieve 4K picture quality display, and 8K TVs will be available at the end of 2018. In contrast, OLEDs are currently only available in Samsung (4K) OLED displays. OLED displays need to be 8K, 10K, the technical challenges are quite high, and even if they overcome various technical challenges, they can make OLED displays that can display 8K picture quality, but the cost may be high and scary.
In the future, the 5G era will enter the 5G high transmission rate, which will allow more high-quality video and video to be streamed between various smart devices. At this time, LCD and OLED displays stand out, and OLED displays may not become mainstream in smart phone displays. Dai Zhenjia stressed that there are still many functions of LCD monitors that have not been developed. In the development of technology, LCD monitors have gradually caught up, and will soon surpass OLED displays.
In addition, Nichia invested a large amount of resources to develop differentiated high-end technology products, and strived to overcome the problems of Micro LED and Mini LED technology and move toward mass production. It is actually quite difficult to reduce the size of the LED to be smaller than sand and to ensure that it can emit light. The technical director of Nichia Chemicals Division II said that the current Micro LED is still in the development stage. Although it is possible to make experimental products, it is necessary to continue to work hard to achieve industrial products. It takes four years.
As for the Mini LED, Sakamoto said that the technology development has been completed and is now ready to enter the mass production stage, but it is impossible to disclose whether it will be mass-produced this year. After all, mass production also has technical, equipment, stability and other issues to be overcome.
