Application of Display Materials

Fuyin provides users with wonderful and excellent visual experience through endless innovation.



In the coming era of Internet of Everything, ubiquitous screens are the core medium for smart life interaction. Fuyin will make a sustain effort on technological breakthrough in the future.



With the continuous update of smart phones, tablet PCs, smart wearable devices, OLED TVs, B2B large touch screens and other products, more electronic manufacturers have launched the research and study on "full-covered screen".


The screen is one of the most expensive components of electronic equipment, as well as the core medium for all electronic equipment to realize their functions and interact with users. Its special nature determines the eligibility rate of overall design and manufacturing of electronic equipment, as well as the user experience.


OCA (Optical Clear Adhesive)


OCA(Optically Clear Adhesive)OCA optical clear adhesive is one of the most important raw material of touch screen. Use optical acrylic glue as non-substant, cover a release film on up and down side. OCA is a kind of non-substant double side bongding tape.


Full-covered OCA Tape


It is a special optically transparent double-sided adhesive with high light transmittance, which is capable to reduce glare, increase display brightness, and provide high transmittance to increase contrast in bright light.


Thin OCA Tape


It is a special optically transparent double-sided adhesive with high light transmittance, which is capable to reduce glare, increase display brightness, and provide high transmittance to increase contrast in bright light.


OCA Bonding Solution

Most display screens may fall off or collide under harsh weather conditions in daily life. The way the screen is laminated to the substrate is the key to solve these concerns. Fuyin's OCA products, represented by full-laminated adhesive, help to enhance the color contrast and make the screen display effect more colorful.

Other Features and Applications of OCA

Fuyin also developed UV and HEV resistant OCA products, and can  provide screen manufacturers with a complete solution for "health screen". In the future, Fuyin will continue to make breakthroughs in thin type OCA and improve the gap absorption capacity while improving adhesive strength, so as to make preparations for exploring the market of curved screen and flexible screen.

Special Properties


Impact resistance: The tape is required to have sufficient cushioning performance to cope with mechanical shock accidents such as drop, collision and vibration.








Adhesion/sealing: The greatest challenge of lamination capability is to realize the seamless bonding between the touch screen and the display module; moisture and warping are the key influence factors.








Corrosion resistance: Mobile phones, smart watches and other devices are highly exposed to sweat, hand sanitizer and other corrosive chemicals in use; it is challenge for OCA tape to protect the functions of such devices after long-term exposure to those substances.








Weather resistance: In different regions with diverse climatic environments, the uncontrollable environmental conditions, such as dryness, high pressure, low temperature and humidity, have a huge impact, but OCA tape with excellent weather resistance can always maintain its performance stably.








Easy to rework: It is helpful to realize effective, safe and low-cost maintenance and recycling of fragile electronic equipment in the aftermarket.
