Huawei Mate 30 Pro Glass Whit Oca

The Huawei Mate 30 Pro features a glass back panel with an OCA ayer. This OCA layer helps to bond the glass panel to the device's frame, providing a seamless and smooth finish. The use of OCA also helps to improve the display quality by reducing glare and reflections.

OCA glass is a type of screen protector for electronic devices that is made from a layer of adhesive material that is optically clear and transparent.   It is often used in smartphones, tablets, and other electronic devices to protect the screen from scratches, cracks, and other damage.   OCA glass is designed to adhere to the device's screen without leaving any residue or air bubbles, providing a smooth and seamless surface for users to interact with.

OCA glass is also known for its high transparency and clarity, which allows for a clear and vivid display of images and text on the screen.

The touch screen glass is typically made from a specialized type of glass, often strengthened or tempered for added durability.  It is designed to be responsive to touch inputs, enabling users to perform various gestures like tapping, swiping, and pinching to control the device and interact with applications.
