LED monitors primarily utilize LED backlight technology. This technology incorporates light-emitting diodes (LEDs) to provide the necessary illumination behind the display panel, which is usually an LCD (liquid crystal display). By employing LEDs, these monitors can achieve brighter images, enhanced color accuracy, and improved energy efficiency compared to traditional LCD monitors that use fluorescent backlighting.

LED backlight technology allows for different configurations, such as edge-lit and full-array backlighting, each offering varied performance in terms of luminosity and contrast. This advancement in display technology directly contributes to the overall viewing experience with better brightness controls and more vibrant visuals.

Other technologies listed, such as OLED, plasma, and cathode ray, serve different purposes and have different operational principles. OLED uses organic compounds to emit light directly from the pixels, plasma employs tiny gas-filled cells to create images, and cathode ray technology is an older form of display technology utilizing electron beams. Each has its unique qualities and is not synonymous with the LED backlighting method used in modern LED monitors.
