What is a White Screen Test?
A white screen test is a diagnostic tool used to troubleshoot issues with display screens, particularly those on electronic devices such as smartphones, tablets, and computers. It involves displaying a pure white image on the screen to test its capabilities and identify any problems.
There are several reasons why a white screen test might be used. For example, it can be used to check the brightness, contrast, and color accuracy of the display. It can also be used to identify any dead pixels, which are small defects on the screen that appear as black or colored dots. A white screen test can also help to determine if the screen is evenly lit, or if there are any dark or uneven areas.
