1. The Importance of OCA Optical Adhesive
The touch function has become the core interface when we use digital devices and IoT services. In this key role, OCA optical adhesive (Optically Clear Adhesive) plays a pivotal role. This special adhesive is not only used to bond transparent optical components such as lenses, but is also an ideal choice for touch screen manufacturing.
Characteristics of OCA Optical Adhesive
OCA optical adhesive, based on optical acrylic adhesive, forms a double-sided adhesive tape by laminating a layer of release film on the upper and lower bottom layers. This material is specially designed for the combination of touch screen panels or glass cover plates and displays. Its high cleanliness, high light transmittance, strong adhesion and UV resistance make it match the refractive index of materials such as glass, PC, PMMA, etc. More importantly, there will be no problems such as yellowing, fogging, detachment from the adhered surface or bubbles after long-term use.
The role of OCA optical adhesive
OCA optical adhesive can provide excellent bonding performance, and will not cause yellowing, debonding and other problems after long-term use, ensuring the durability of the touch screen. Looking forward to the future market, DataBridge data shows that the global OCA optical adhesive market size in 2021 is US$2.07 billion, and it is expected to surge to US$4.74 billion by 2029.

3. Application Examples
Application of OCA Optical Adhesive in Display/Optical Devices
OCA optical adhesive plays a vital role in the field of display/optical devices. It is widely used in LCD screens, mobile phone lenses, optical lenses, flat panel display devices and other aspects, providing key support for the performance improvement and quality assurance of these products. OCA optical adhesive provides important performance improvement and protection in the fields of LCD screens and mobile phone lenses, and is a key material for improving display effects and lens quality.
Application of OCA on LCD screens
OCA optical adhesive plays an indispensable role on LCD screens. It is not only used to improve the transparency and brightness of LCD screens, but also enhances its contrast and color saturation, thereby significantly improving the display effect of LCD screens. In addition, the excellent performance of OCA optical adhesive also helps to extend the service life of LCD screens, ensuring their consistent quality and performance.
Mobile phone lens
Mobile phone lens is an indispensable part of modern smartphones, which is responsible for capturing the beautiful moments in life. OCA optical glue can improve the light transmittance and impact resistance of mobile phone lenses, ensuring that they can capture clear images and extend their service life. OCA optical glue plays a key role in this process. It can improve the light transmittance of the lens and reduce light scattering, thereby ensuring that the mobile phone lens can capture clearer and more delicate images. In addition, OCA optical glue can effectively resist external impact, protect the mobile phone lens from damage, and further extend its service life.
