Lighting Emitting Diode (LED)

“LED” is an abbreviation for “Light emitting diode”. An LED is a solid-state electronic device than emits light when energized by applying power. The LED die is mounted to a lead frame(see below) which is encapsulated in an epoxy lens. The epoxy lens directs the emitted light and protects the LED die from physical damage. The lead frame provides the electrical connections, the physical mounting and a thermal heat sink to remove the heat generated within the LED. A display manufacturer must have an in-depth understanding of LEDs and their properties, as well as use high-quality components in order to develop effective designs than stand the test of time.
