IMPROVEMENTS IN EXTERNAL LIGHT EFFICIENCY OF LIGHT EMITTING DIODES
摘要
<p>A method to improve the external light efficiency of light emitting diodes, the method comprising etching an external surface of an n-type layer of the light emitting diode to form surface texturing, the surface texturing reducing internal light reflection to increase light output. A corresponding light emitting diode is also disclosed.</p>
