1. Along a certain Angle to or tear the polarizer, it is easier to tear along the Angle of the polarizer;
2. Look at the words or points on the polarizer, and their arrangement direction is the direction of the polarizer.
3. Take a polarizer with a known Angle and overlap the polarizer to be measured, if the degree of light transmission of the two overlapping pieces is almost the same as the degree of light transmission of one, then the two angles are the same, and on the contrary, there is an Angle difference. The rotation Angle is adjusted to the degree that the cross is most opaque (that is, the darkest time), and the Angle between the horizontal and the known Angle of the polarizer is the Angle of the polarizer to be measured.

The growing demand for TVs and the increasing competition among manufacturers have created a highly saturated market for polarizing films. As a result, it is crucial to use high-quality polarizing film to ensure the best picture quality and longevity of your TV.

Conclusion: Measuring the angle of the polarizing film is an essential step in the process of repairing a TV. With the right tools, knowledge, and materials, you can ensure that your TV has the best possible picture quality and meets the specific needs of your customers. Always remember to handle the polarizing film with care and use high-quality materials for optimal results.
