Flat-Panel (LCD) Monitors
Flat-panel, or LCD, monitors, most commonly found on laptops but also common with many desktop computers, have not been found to emit any UV light. The Xeroderma Pigmentosum Society attempted to measure UV levels of LCD screens, but no UV radiation was detected at even the lowest levels.

Blue Light
Though UV light is not such a problem, computer monitors of all types and televisions have been found to emit blue light. While dangers associated with blue light are also mild to none, studies have shown that blue light causes the brain to be more alert, and sleep comes less easily. Because of this, it is best to stop using a computer at least an hour before bedtime and turn off any monitors that may be on in the bedroom for a better night's sleep.
