What is the difference between LCD, LED, and OLED monitors, and how do their display technologies affect performance?

LCD (Liquid Crystal Display) monitors use a backlight (usually CCFL or LED) to illuminate pixels, which then filter light to produce colors. LED monitors are essentially LCDs that use LED backlighting instead of CCFL, offering better brightness, contrast, and energy efficiency. OLED (Organic Light Emitting Diode) monitors, on the other hand, do not require a backlight—each pixel emits its own light. This allows OLEDs to achieve true blacks, higher contrast ratios, wider viewing angles, and faster response times, making them ideal for gaming and professional media editing. However, OLEDs are more expensive and can suffer from burn-in issues, while LCD/LEDs are more affordable and durable.
