A phone screen is important as it is one of the most important components of the
phone. But it can be difficult to handle due to its small size, fragility, and complicated calibration. Testing the screen is also a crucial first step when you receive the product, to ensure it is functioning well before installation. At Revivo, we require that our customers test all screens before installation so that we can identify any issues and replace or refund products when necessary.
To help you with this, we have put together a step by step guide to help you test phone screens.
#1 Inspect the screen for any visible damage: Before testing the screen, visually inspect it for any cracks, scratches, or other visible damage. If you notice any issues, it's best not to proceed with the installation. You should report the issue to the supplier.
#2 Connect the LCD flex cable to the motherboard port: This ensures screen compatibility with the phone. Do not force the flex cable to the port because it might cause damage to the port and LCD flex cable. Do not glue or screw the screen on at this point.
#3 Test the touch response: To test the touch response of the screen, turn on the phone and try tapping on various parts of the screen to check if it responds accurately. You can also swipe left, right, up, and down to ensure that the screen recognizes your touch accurately.
#4 Test the color display: To test the color display, open up an image or a video with different background colors and check if the colors are vibrant and accurate. You can also check if the screen has any dead pixels by displaying a completely black image and looking for any small white dots on the screen.
#5 Check for backlight bleeding: To check for backlight bleeding, display a black image and look for any light bleeding from the edges of the screen. If there is any, it could indicate a problem with the backlight.
#6 Check for screen uniformity: To check for screen uniformity, display a white image and check if the screen has any areas that appear darker or lighter than others.
#7 Check for viewing angles: To check for viewing angles, hold the phone at different angles and check if the display remains clear and visible from all angles.
#8 Test the camera: Finally, test the camera to ensure that the screen is not interfering with the camera's functionality. Take a few photos and check if they are clear and sharp.
By simply following these steps, you can test a phone screen and ensure that it is not damaged for your customer!
