Apple launched an active organic light-emitting diode (AMOLED) mobile phone, driving the AMOLED display trend, the upstream chemical industry of the panel said that if the AMOLED panel to be folded, the problem of the panel and the protection substrate is too thick.

Yongjie Polymer, an upstream chemical raw material industry that put into the panel, said today that the current foldable AMOLED display products developed in Taiwan have incomplete upper board integration technology, and the main technical gap is that the existing protective cover plate and substrate are too thick to achieve the goal of flexural overlap.

Yongjie Polymer pointed out that in response to the above phenomenon, AMOLED display upstream and downstream manufacturers through alliance and division of labor to improve the problem, including combining polarizing film, transparent polyimide substrate, hard material manufacturers for integrated development, in order to optimize the overall structural design, so that AMOLED panel products have high reliability and can be folded repeatedly.

Yongjie said that since obtaining the technology transfer of key components of foldable organic light-emitting diode displays from the Institute of Industry and Research last year, it has actively invested in the research and development of high-hardness wear-resistant material formulas, cultivated relevant talents, built production equipment, and successfully cooperated with two well-known domestic science and technology manufacturers with the strong assistance of the Institute of Industry and Research, invested in the "integrated development plan for foldable AMOLED ultra-thin multi-functional upper board", and obtained the integrated R&D plan subsidy of the Ministry of Economic Affairs.

Yongjie believes that the implementation of the plan will help the R&D team of the alliance manufacturers to form, upgrade technology, and expand domestic and foreign markets, and can completely connect the foldable AMOLED industry chain, assist the upgrading of the domestic panel industry, promote the development of the domestic soft display industry, and strengthen the competitiveness of domestic system factories in the international market.

According to the analysis of IHS, a global market research agency, the global revenue of foldable AMOLED panels will surpass that of hard AMOLED panels for the first time since the third quarter of 2017, and the global foldable AMOLED panel revenue in 3 will increase by 2017% compared with 2016; In 150, flexible AMOLED panel revenue will increase by $2018.450 million.

This screen on some mobile phones occupies almost half of the cost of the mobile phone, such as the recently popular curved screen mobile phone, accidentally broken, you say distress no. The quality of the screen also indirectly imposes the consumer's aesthetics and desire to buy.

What about the mobile phone screen, mainly look at two parameters, the first is the resolution of the screen, and the second is the material of the screen.

The resolution can be understood by everyone, that is, the larger the value, the clearer, and it is no longer the era of the grainy explosion of mobile phones, but the higher the resolution, the more power will be consumed. At present, the minimum resolution on the market is 720P, the standard is 1080p, and the high-end one reaches 2K or 4K resolution.

The material of the screen is divided into LCD and LED, the former represented by Apple's IPS screen, and the latter represented by Samsung's AMOLED.

The advantages of IPS screen are: soft and natural color, wide viewing angle, no color change when viewed from any angle. The disadvantages are: light leakage, poor contrast.

The advantages of AMOLED screen are: bright colors, thinner and thinner than IPS. The disadvantage is: because the pentile arrangement causes the screen to be viewed from different angles, the color will be different, which is the origin of the color screen blue-green screen, the solution is to increase the PPI, so a screen 5.5 inches and above screen 2K is very necessary.

IPS manufacturers are very common, such as high-end Sharp, Sony, LG, etc., and low-end Tianma. The 2K L screen is basically Sharp's products.

95% of the world's AMOLED is produced by Samsung, and the remaining share is LG production, and the only manufacturer that can mass-produce 2K resolution AMOLED screens is Samsung.
