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

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.

Notes:

• The test card is used only as an auxiliary detection tool and its accuracy is not 100%. If the screen is an original polarized screen, it will not be distinguishable. The test card is applicable for screen detection of the iPhone 12-17 series.

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.

• Open the phone's memo function and set the screen background to white. Align the card edge left against the phone's screen border. The deviation of the test card angle will affect the test results.

• When observing,look directly at the test card. If the observation angle is too large, it may affect the test result.
