What is LED?
LED is standed for Light Emitting Diode,a kind of semiconductor which is used to give and receive the electronic signal into infrared rays or light, using the characteristics of compound semiconductor. This is used for household appliances, remote controller, electric bulletin board, various kinds of automation appliances.
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. ALED 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.
