LED televisions are a type of flat-screen display that use light-emitting diodes (LEDs) to illuminate the screen. They are known for their bright colors, high contrast, and energy efficiency compared to older technologies like LCD and plasma TVs. LED TVs come in various sizes and resolutions, including 4K and 8K, providing options for different viewing preferences. These televisions are popular for their slim design and lightweight construction, making them easy to mount on walls or place on stands. Many models also offer smart features, allowing users to access streaming services and apps directly from the TV.
