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. |
