We test for the following defects on all of our LCD screens:
- Bad back-light
- Dead pixels
- Grey area
- Screen burns
- Water spots
- Edge pressure damage
- Digitizer functions
In most all cases, any of these failure reasons results in a failed LCD assembly.
Our test is conducted with specialized testing boxes for iPhone and our internally developed (publicly available) LCD Screen Tester app for Android.
The test runs through a range of color pallets, which increased the chances a trained eye can see the above defects.
