CompTIA A+ Question C-33

Which of the following panel types consumes the MOST power?

A. Plasma
C. LED with no backlight
D. LED with backlight

Correct Answer: A

A Light emulsification diode with a backlight consumes more power than an LCD or plasma. First the LED needs power. The backlights are another component that requires power. Although the power an LED consumes is far less than what CRT monitors consumed.
