OCA for Under-Display Camera

Description

OCA for Under-Display Camera (UDC) is a specialized optical clear adhesive engineered for next-generation smartphone displays featuring under-display camera technology. This advanced adhesive material is designed to support the optical requirements of camera modules placed beneath the display panel while maintaining excellent screen clarity and touch performance.

Under-display camera technology allows smartphone manufacturers to achieve true full-screen displays by integrating the front camera beneath the display. This innovative design requires highly optimized optical bonding materials to ensure that light can pass through the display layers with minimal distortion.

AxisTape Under-Display Camera OCA provides exceptional optical transparency, controlled refractive properties, and excellent flow performance, enabling precise bonding in camera areas while maintaining uniform display quality across the entire screen.

This product is widely used in:

• smartphones with under-display cameras
• advanced OLED display modules
