Patent ID: 7523028

Claim:
A method of simulating a plurality of characteristics of a light-emitting device, executed on a computer device, comprising: calculating a plurality of data sets using the computer device including a first data set comprising a light extraction efficiency, a second data set comprising a total emission power factor of excitons, a third data set comprising a photometric quantity and a fourth dataset comprisinq an emission power factor and a power reflector; storing said plurality of data sets in a first storage device; calculating a concentration of carriers in the light-emitting device using the computer device and for storing a carrier recombination rate as an exciton formation rate in a second storage device; reading the exciton formation rate and the second data set calculating using the computer device a concentration of excitons using a total deactivation speed of an exciton; and calculating, using the computer device, and displaying on a display device, device characteristics of the light-emitting device in a measurable dimension by using a data set, selected from the plurality of data sets other than the second data set and an emission deactivation rate, calculated from the concentration of excitons; wherein calculating said first data set comprises calculating the light extraction efficiency as a function of a wavelength and a position, the light extraction efficiency responsive to a fraction of dipoles from a plurality of dipoles having a moment parallel to a light-emitting surface; wherein calculating said second data set comprises evaluating a wavelength integral of a light extraction efficiency; wherein calculating said third data set comprises calculating a photometric quantity using a luminous intensity in a front direction and a total luminous flux emitted; and wherein calculating said fourth data set comprises calculating an exciton emission energy spectrum responsive to a reflection loss caused by external light by determining a power corresponding to an amount of light reflected in an incident direction using a Fresnel coefficient.
