Material: Composite material; Thickness: 0.25mm / 0.001 inch; Dimension: 20x15.2cm / 7.9x6 inch; Packing List: 2 x Polarized Film Sheets(one is 0 degree angel and the other one is 90 degree angle) | Advantage: The polarized film measures a thickness of 0.25 millimeters. It comes with protective films on both sides, with one side being adhesive and the other side non-adhesive (Need to remove the protective film which is on the adhesive side when you try to use it). | Instruction: Keep the device powered on, align the adhesive side of the film onto the screen, and rotate the polarized film 360 degrees clockwise. Please try to find a clear position and mark it. Finally, simply cut it into the desired shape and ready for using it after removing the surface dust. | Application: The polarizing film sheet is suitable for light scattering, polarized light projects/experiments, as well as repair or upgrade dashboard displays, electric motorcycle dashboard displays, small LCD screens, projector screens, electronic watches and other LCD display devices. | NOTE: Polarized film sheets need to be rotated during installation to ensure proper alignment with the screen. Each screen has a different angle of polarization, so by rotating the film, we can find the optimal position where the film aligns perfectly with the screen's orientation. This rotation allows for the good performance and clarity of the polarized film when used with a specific screen angle.
