The correct answer is LCD, which stands for Liquid Crystal Display. LCDs utilize a fluorescent backlight to create a visible image. This differs from LED screens, which use light-emitting diodes for backlighting, offering better energy efficiency. Plasma displays, commonly used in large TV screens, use small cells containing electrically charged ionized gases, unrelated to fluorescent lighting. OLED, or Organic Light-Emitting Diode displays, generate light through an organic compound layer that emits light in response to an electric current, not requiring a backlight at all.
