Considering limits for resolving EMZ features yields a characterization by two parameters only. This enables to compare different EMZ results numerically and to define optimization targets that can be observed experimentally. Exemplary data on current-dependent EMZ shift illustrate the application of the method.enemission pattern analysisoptical simulationOrganic LEDprofile of the emission zoneconference paper
