Which type of display has the highest contrast ratio?

  1. LCD

  2. OLED

  3. Plasma

  4. LED

The correct answer is: Plasma

A Plasma display has the highest contrast ratio compared to the other options. This is because plasma displays have a deeper level of black and a brighter level of white, resulting in a larger difference between the dark and light shades. LCD and LED displays have a higher ratio than traditional CRT displays, but they cannot match the contrast ratio of plasma displays. OLED displays also offer high contrast ratios, but they may not be as consistent as plasma displays when it comes to maintaining deep blacks.
