C4UV is Feaglet’s iPhone cover glass solution developed for professional flexible OLED glass-only refurbishment. It combines precision cover glass with pre-applied C4UV anti-wrinkle OCA for qualified repair factories and experienced technicians.
Pre-Applied C4UV Anti-Wrinkle OCA
Designed for Flexible OLED Refurbishment
Controlled Laser Rework Compatibility
Professional Use Only
C4UV is intended for professional refurbishment workflows where optical appearance, OCA behavior and rework capability require closer process control.
The C4UV glass and OCA configuration is designed for iPhone flexible OLED refurbishment. Compared with Feaglet Original Series using Mitsubishi OCA, C4UV requires more precise technician alignment before initial contact because of its stronger OCA flow characteristics.
The anti-wrinkle feature refers to the optical appearance of the OCA layer after correct lamination. Under Feaglet-defined UV visual inspection conditions, C4UV OCA is designed to reduce visible OCA wave patterns after proper lamination.
*Final appearance depends on display condition, glass alignment, lamination control, debubbling process and technician experience.
The C4UV OCA configuration may support secondary laser-assisted separation of the display panel and cover glass in qualified rework workflows.
This capability can help professional refurbishment operations manage selected rework situations. Rework suitability depends on the original display condition, laser equipment, process validation and technician skill.
*Feaglet does not recommend laser rework for untrained users or uncontrolled repair environments.
C4UV OCA has stronger flow characteristics than the Mitsubishi OCA used in Feaglet Original Series. Technicians should complete alignment accurately before initial glass-to-display contact.
Recommended professional controls include:
Model-specific positioning fixture
Clean and level display bonding surface
Accurate first-contact alignment
Controlled lamination and debubbling workflow
Incoming and final visual inspection
Process validation before volume production
*Detailed process guidance and product-specific technical data are available for qualified customers upon request.
C4UV is Feaglet’s iPhone cover glass product with pre-applied C4UV anti-wrinkle OCA, developed for professional flexible OLED refurbishment.
It refers to OCA behavior and optical appearance after qualified lamination. C4UV is designed to reduce visible OCA wave patterns under Feaglet-defined UV visual inspection conditions.
No. C4UV has stronger flow characteristics and requires more accurate technician positioning before initial contact.
It may be used in qualified laser-assisted rework workflows. Technicians must validate their equipment and process before production use.
The key difference is the OCA configuration. Original Series uses Mitsubishi OCA for mainstream refurbishment workflows, while C4UV uses anti-wrinkle OCA for flexible OLED workflows requiring closer alignment and process control.
