Turn your display or mobile device into a ultra-bright pure white flashlight screen. Perfect for finding screen dust, dead pixels, photography backlighting, or reading in the dark.
A white screen is used to test monitors for dead pixels, check display backlight bleed, trace physical drawings like a light table, provide webcam fill light, and clean screen surfaces.
Simply visit this page and press 'F' or double-click to enter fullscreen mode. Your screen will act as an ambient soft white light.
