Definition of LED TV

LED, which stands for Light Emitting Diode, is a technology that has revolutionized the television industry. An LED TV is a type of television that uses LED backlighting to illuminate the display panel. Unlike traditional LCD (Liquid Crystal Display) TVs that use fluorescent tubes for backlighting, LED TVs utilize an array of light-emitting diodes to produce light.

Explanation of LED Technology

LED technology works by utilizing tiny electronic components called light-emitting diodes to emit light when an electric current passes through them. These diodes are mounted behind the screen of the TV and emit light directly or indirectly onto the display panel. The use of LED backlighting allows for precise control of brightness levels, resulting in improved picture quality and overall visual experience.
