The following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies.
These are the most often used technologies for television and computer displays.
A less detailed comparison of a wider variety of display technologies is available at Comparison of display technology.
OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight,[35] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.
