Front Screen Outer Glass Lens with OCA Optically Clear Adhesive. Before installation, test the part without removing any protective film or tags. Take precautions against static electricity by using an ESD (electrostatic discharge) strap to prevent damage to electronic components. Wear eye protection and handle with care to avoid injury from glass splinters. Screen replacement is a delicate component; testing before installation is strongly recommended. Perform a simulation test by connecting the motherboard, LCD or screen, and cable with the replacement part, then power on the device. If the test is successful, proceed with installation. If the screen does not display, contact support immediately. Do not force installation if issues are present. No responsibility is assumed after the screen is installed. Avoid over-bending the LCD cable; bending beyond 90 degrees may result in display issues such as a black screen.
