Abstract
A method is used for measuring injection energy associated with an organic light emitting diode display device. The method includes disposing the display panel inside a chamber and controlling temperature inside the chamber. The method further includes determining a plurality of electric current values corresponding to a plurality of temperature values for each voltage value of plurality of voltage values, the plurality of voltage values being associated with voltages provided to the organic light emitting member. The method further includes calculating a plurality of injection energy values using the plurality of electric current values and the plurality of temperature values.
