Touch screen fully bonded water-based adhesive, also known as Liquid Optical Clear Adhesive (LOCA), is a special adhesive mainly used for bonding transparent optical components. It has the following significant functions and advantages:
1. High transmittance: The fully bonded water-based adhesive is colorless and transparent, with a high transmittance of over 98%, ensuring that the screen still has a good display effect after bonding.
2. Isolate dust and moisture: Compared with traditional frame pasting technology, full lamination technology uses water-based glue to fill the gap between the display screen and touch screen, effectively preventing the intrusion of dust and moisture and maintaining the cleanliness of the screen.
3. Improve display effect: Full lamination technology eliminates the air layer between screens, reduces the reflection of light and the loss of transmitted light, thereby improving brightness and enhancing display effect.
4. Reduce noise interference: Full lamination tightly integrates the touch screen with the display panel, effectively reducing the interference of noise on touch signals and improving the smoothness of touch operations.
5. Thinner body: The use of fully bonded water-based adhesive only increases the thickness by 25 μ m-50 μ m, which can make the body thinner compared to ordinary bonding methods.
6. Simplified assembly: The assembly of the fully bonded module and the entire machine can be directly fixed by snap fasteners or locking screws, simplifying the assembly process, reducing assembly costs, and helping to achieve narrow frame design.
7. Good bonding strength: The fully bonded water-based adhesive has high bonding strength and good vibration resistance, ensuring the good operation of the product during continuous driving and reducing the risk of glass breakage under impact.
8. Suitable for complex structures: Fully bonded water-based adhesive is suitable for large-sized bonding, bonding of curved surfaces or more complex structures, as well as bonding of higher ink thickness or uneven surfaces.
9. Cost effectiveness: Compared with traditional OCA tape, the cost of fully bonded water-based adhesive is lower, and due to its liquid nature, it can flexibly adjust the bonding size and thickness to meet diverse product needs.
10. Easy rework: The rework of fully bonded water-based adhesive is relatively easy, which is an advantage in the production process, especially when facing complex or large-sized bonding operations.
The characteristics of fully bonded water-based adhesive make it an ideal choice for high-end applications such as car displays, providing superior display effects and more reliable product performance.
