LED stands for Light Emitting Diode, a semiconductor-based light source that emits light when an electric current passes through it. In the context of electronics and mobile devices, LEDs are widely used for display screens, backlighting, notification indicators, and flashlights.
LED technology is known for its energy efficiency, long lifespan, and compact size, making it ideal for modern smartphones, TVs, monitors, and other gadgets. Unlike traditional incandescent bulbs, LEDs produce minimal heat and offer brighter, more vibrant colors.
In displays, LEDs can be used in various forms, including standard LED-backlit LCDs and advanced technologies like OLED (Organic LED) and Mini-LED, which provide better contrast, deeper blacks, and improved power efficiency.
