RF4 RF-T01 Original Screen Identification Card for iPhone 12 to 17Pro Max

• To identify an original iPhone screen, remember this "optical mnemonic": 3 Blue, 5 Orange, 7 Dark blue.
• This is the unique spectral code of the original polarizing film.No matter how closely the replica screen is made, it still won't pass this test.
• Product Usage Tutorial And Reference Instructions:
• Before testing, remove the protective film on the phone to ensure the screen is in its original display state.
• Adjust the phone's brightness to the maximum.
• Ensure that the current testing environment has a moderate brightness. Excessive brightness or darkness will cause color deviations from the reference image, but will not affect the test results.
