How do you guys test LCD Screens?

We only test our LCD’s using PHONES. Phones are opened and attached to LCD connector cables to be created into testing devices.

Say NO to companies that use testing boxes that are available online.

1. These boxes are unreliable as they provide inaccurate results. These boxes can easily fail 10-30% of screens that are completely working.

2. Your LCD came off of a phone and is going to be used on a phone so it is best practice to test using a phone.

We test every screen in 3 colours: Black, Gray and White. We specifically test screens for:

  • Backlight
  • Dead pixels
  • Red Haze
  • Lines
  • Screen burns
  • Pressure spots
  • Touch functionality
