Apple introduced an active organic light-emitting diode (AMOLED) mobile phone to drive the AMOLED display trend. The panel upstream industry said that if the AMOLED panel is to be folded, the problem of the panel and the protective substrate being too thick must be overcome.
Yongjie Polymer, a chemical raw material supplier in the upstream of the panel, said today that the foldable AMOLED display products developed in Taiwan are incomplete in the integration of the upper board. The main technical gap is that the existing protective cover and the substrate are too thick to be scratched. The twisted target.
Yongjie Polymer pointed out that in view of the above phenomenon, the upstream and downstream manufacturers of AM OLED display can improve the problem through alliance and division of labor, including integrated development with polarizing film, transparent polyimide substrate and hard material industry to optimize the whole. The structural design makes AMOLED panel products highly reliable and can be repeatedly folded.
Yong Jie said that since the transfer of the key components of the OLEDs that can be folded by the Institute of Industrial Science and Technology (IRO) last year, the company has actively invested in the research and development of high-hardness and wear-resistant materials, cultivated relevant talents, built production equipment, and assisted in the ITRI. Under the company, we successfully cooperated with two famous domestic technology giants to invest in the “Integrated Development Plan for the Foldable AMOLED Ultra-thin Multi-functional Board” and received the subsidy from the Ministry of Economic Affairs for integrated R&D.
Yongjie believes that the implementation of the plan will help the alliance manufacturer's R&D team to form, upgrade the technology, and expand the domestic and international markets, and can complete the cascade of AMOLED industry chain, assist the domestic panel industry upgrade, and promote the development of the domestic soft display industry. Strengthen the competitiveness of domestic system plants in the international market.
According to the global market research organization IHS analysis, since the third quarter of 2017, the global revenue of the foldable AMOLED panel will surpass the hard AMOLED panel for the first time. In 2017, the global foldable AMOLED panel revenue will grow by 150% compared with 2016; in 2018 The flexible AMOLED panel revenue will be seen at $4.5 million. (Source: Central News Agency)
The screen on some mobile phones almost occupies half of the cost of mobile phones. For example, the recently popular curved screen mobile phone is accidentally broken, and you say it hurts. The quality of the screen also indirectly reflects the consumer's aesthetic and purchasing desire.
Mobile phone screen, mainly look at two parameters, the first is the resolution of the screen, the second is the material of the screen.
The resolution can be understood by everyone, that is, the bigger the value, the clearer it is. It is no longer the era of cell phone particle explosion, but the higher the resolution, the more electricity will be consumed. At present, the market is at least 720P resolution, the standard is 1080p, and the high end is 2K or 4K resolution.
The material of the screen is divided into LCD and LED. The former is represented by Apple's IPS screen, and the latter is represented by Samsung's AMOLED.
The advantages of the IPS screen are: soft and natural color, wide viewing angle, and no discoloration when viewed from any angle. The disadvantages are: light leakage, poor contrast.
The advantages of the AM OLED screen are: bright colors, lighter and lighter than IPS. The disadvantage is: because the pentile arrangement causes the screen to be viewed from different angles, the color will be different. This is the origin of the blue-green screen of the partial color screen. The solution is to increase the PPI, so the 2K on the screen of 5.5 inches and above is very good. necessary.
IPS manufacturers are very common, such as high-end Sharp, Sony, LG, etc., the middle and low end have Tianma. The 2k L-screen is basically Sharp's product.
There are very few AMOLED manufacturers. 95% of AMOLEDs in the world are produced by Samsung. The remaining share is mostly LG, and the only manufacturers that can produce 2k resolution AMOLED screens on a large scale are Samsung.
