A QLED TV is a type of television that uses Quantum Dot technology to enhance picture quality. This technology involves tiny semiconductor particles that emit different colors when exposed to light, resulting in brighter images and a wider color spectrum. QLED TVs are known for their high brightness levels, making them suitable for viewing in well-lit rooms. These TVs are typically associated with brands like Samsung, which has popularized QLED technology. QLED TVs also support features like 4K resolution and HDR (High Dynamic Range), providing a more immersive viewing experience with improved contrast and detail in both dark and bright scenes.
