This 24-inch LEDA light-emitting-diode (LED) is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electro luminescence where incoherent and narrow-spectrum light is emitted from the p-n junction. HDTV comes equipped with built-in speakers and is VESA Wall mountable. The display is energy star rated and comes with our Photo Gallery Feature, which allows the user to view JPEG images through its USB direct playback feature. It features a 2,000,000:1 dynamic contrast ratio, a 5 ms response time and its PC compatible.
