1. Nowadays, OCA optical film products have achieved a large number of breakthroughs in VR and mobile phone terminal brands.
Many companies have achieved independent research and development and mass production supply including optical tape, OCA optical glue, and precision coating liquid. In recent years, major manufacturers are also on the road of material application innovation, and the globalization of the OCA optical adhesive industry is gradually taking shape. Many major manufacturers have broken through the monopoly of foreign companies in fully laminating OCA optical adhesives, and have broken the market perception.
2. It is understood that the full name of OCA optical adhesive is Optically Clear Adhesive, which mainly refers to a special double-sided adhesive film that is used for bonding between two flat optical components and has no substrate; OCA is used for bonding transparent optical components (such as lenses, etc.) ) special adhesives, which belong to the category of pressure-sensitive adhesives.
Moreover, OCA optical glue is used to attach the LCD module and TP on the mobile phone in daily life, and can also be used to attach notebooks, LCD screens, tablets, curved screen mobile phones, folding screen mobile phones, education screens, blind Hole screen fit.
3. It’s just that many manufacturers are currently stuck in the OCA optical adhesive market, and there are more and more situations where the upstream is “eating meat” and the downstream is “drinking soup”.
At the same time, the competition in the OCA optical adhesive industry has become increasingly fierce. During this period, touch screen equipment has promoted the development of the industry. Some optoelectronic giants said: In the future, the implementation of ITO conductive film construction projects should be accelerated to increase the proportion of OCA optical glue business revenue.
4. According to reports, in recent years, the cooperation between major optoelectronic giants has mainly focused on investment and expansion of OCA optical film projects and optical film R&D and production projects.
The "new breakthrough" in these cooperations is: OCA optical adhesive film cut into the rework field. A large number of OCA optical adhesive manufacturers have completed the B+ round of financing of nearly 100 million yuan, and other capital companies led the investment. OCA optical adhesive products have completed the verification of each screen factory, and mass production is just around the corner.
5. On the other hand, in 2019, Samsung Electronics was entangled in lawsuits, and infringement lawsuits cast a shadow over its development, and disputes continued.
In 2021, Mitsubishi Chemical filed an optical glue infringement lawsuit against Korean company TMS; and Seoul Semiconductor started a smartphone infringement lawsuit. As early as 2011, Mitsubishi Chemical sued Intematix in South Korea for infringing its red phosphor patent.
6. In 2010, OCA optical tape has been known as the king of optical products in Japan.
Today, many years later, the rapidly developing OLED folding screen challenge heralds a "heavenly mission" for OCA. OCA tape is undoubtedly the leader in functional composite materials.
