What Is a 4k 3D LED TV?


Quick Answer

A 4K 3D LED TV is a television with a 3840 x 2160 pixel or 4096 x 2160 pixel display that is capable of playing three-dimensional content and uses a light-emitting diode, or LED, backlit LCD screen to play video. These additions to the basic television deliver enhanced Ultra HD video quality that seems to leap off the screen and has greater energy efficiency than standard LCD screens.

The 4K designation refers to the approximately 4,000 pixels that make up half the resolution measurement on the 4K television, delivering up to four times more pixels than 1080p high-definition televisions. More pixels equates to higher potential detail. This earns the television the distinction of being an Ultra HD TV instead of an HD model. Movies and games designed to harness 3D technology add a layer of depth that uses both eyes to create three-dimensional models that appear to break the fourth wall. Many televisions of this sort require special glasses or force users to sit a specific distance from the screen for best effect.

LED technology reduces energy consumption in LCD televisions while delivering more balanced color saturation, allowing for an array of hues and colors on the screen. LED televisions with full array backlighting also have little or no light leakage, ensuring they primarily illuminate the space in front of the screen without casting light elsewhere. TVs using edge-lit LED variants may also be far thinner than other LCD models.
