LED manufacturing process stage, to enhance the efficiency of LED light-emitting method. Raise LED luminous efficiency, which is to enhance the external LED components to the photon number can be measured by dividing the number of electrons between the external injection ratio of LED. The main factors affecting the luminous efficiency of internal quantum efficiency (Internal Quantum Efficiency) and the efficiency of taking light (Light Extraction Efficiency) to upgrade. The internal quantum efficiency, said second light-emitting layer from the LED emits photons per second, divided by the number of electrons injected from the outside. Simply put, that is, electro-optical conversion efficiency of LED components themselves mainly with their own properties, such as components, materials, components, energy band, defect, impurity, and the composition and structure of components and other related epitaxy.
