    Knowledge LED Tutorial: LED Chips and LED Packages

    An LED chip is a bare semiconductor die that has a p-n junction sandwiched between oppositely doped layers. LED chips have a narrow spectral band and emit light of a single color. The selection of semiconductor and doping materials determines the spectral power distribution of light emitted from...

    Knowledge What is an LED die (LED chip)?

    An LED die, more commonly known as an LED chip, is a small block of compound semiconductor material that has a p-n junction (positive-negative junction) sandwiched between oppositely doped layers. Under biased conditions the p-n junction can break down causing current to flow from the p-side of...
