Abstract
A method for measuring optoelectronic characterstics of an organic light emitting diode. A computer, a power supply and a cavity are provided. The cavity has a tooling, on which at least one photodiode is mounted. A high temperature, high humidity, or high temperature and humidity condition is applied to the cavity. The computer is used to control the power supply for supplying a current or a voltage to the organic light emitting diode to generate a light with a brightness. A signal carrying brightness information of the light is then transmitted to the computer (two signals with different brightness have to be input to the computer first) for performing data process.
