Answer / Keerti Pandey

LED (Light Emitting Diode) and LCD (Liquid Crystal Display) are both display technologies, but they operate differently. An LED emits light when an electric current passes through it, while an LCD does not emit its own light but uses a backlight to illuminate pixels that contain liquid crystals which block or filter the light. LEDs are typically smaller and more energy-efficient than LCDs, but LCDs offer better image quality and larger display sizes.
