Recommendations for use
-
LCD Customization
To meet the diverse needs of the LCD market, CDTech can provide size customisation services, including AA size and OD size. We can also support customised square screens(for smart home and industrial control) and round screens(for automotive, cooking equipment, etc.) and other distinctive sizes.
-
Touch Panel Customization
We provide custom cover lens solutions with various shapes, thicknesses (ranging from 0.55mm to 6.0mm), and surface treatments such as AG (Anti-Glare), AF (Anti-Fingerprint), and AR (Anti-Reflection). We can adhere foam to the cover surface and ring-type foam adhesive (like 3M VHB/Tesa) on the back for better installation and dust/water resistance. For UV resistance in outdoor applications, we use special UV-resistant inks or ceramic prints on tempered glass. We can also customize higher-spec cover lenses, like Gorilla and Dragontrail, for IK rating requirements.

Usage Guidelines
CDTech’s LCD products have high quality reliability, allowing customers to use them for a long time without easily breaking down. However, we also suggest that customers will follow the correct operation or storage methods when using them: try to avoid direct contact with the FPC gold fingers with hands to prevent oxidation. It is recommended to wear anti-static gloves or finger cots for operation, and ensure effective grounding. When the products are not used for a long time, they should not be stored in high-temperature and high-humidity environments for a long time, but should be stored in a warehouse with appropriate temperature and humidity.
