If you can cut by yourself, it is recommended to buy a larger size and cut the appropriate size by yourself. For example, a 45 degree polarizer with a length and width of 400 * 300mm can be cut from the middle into two 135 degree 300 * 200mm polarizers. For example: now we need to replace the polarizer of a 12.1-inch notebook screen. After tearing off the polarizer of the original screen, the screen will not display anything, white. We #39;re going to reattach the polarizer to the screen and let it display again. Place a 45 degree polarizer horizontally on the surface of the screen (you can #39;t put it upside down, the side with glue is below, it doesn #39;t matter if it #39;s upside down). At this time, you can see the content displayed on the screen through the polarizer. If the display is normal, it means that the screen is 45 degrees. If the color is biased or reversed, we will rotate the polarizer until the normal position is displayed. Measure the rotation angle with a protractor. The 45 degree + (-) rotation angle is the angle of the screen. Common screen angles are 0 degrees (or 180 degrees), 45 degrees, 60 degrees, 90 degrees and 135 degrees
