1. 有關 烙印 (Burn-in): LCD computer monitors, including the display panels used in laptop computers, are not susceptible to burn-in because the image is not directly produced by phosphors.
2. 有關 壽命 (Lifetime): Using a screensaver with a flat panel or LCD screen instead of powering down the screen can actually reduce the lifetime of the display, since the fluorescent backlight remains lit and ages faster than it would if the screen was turned off completely.
也因為這樣,2009年最新的 Windows 7,<螢幕保護裝置>預設是關閉的,<關閉顯示器>預設是開啟的。
