Abstract

Various examples are provided related to compensating brightness of a display using a vertical organic light emitting transistor that suppresses variations in brightness over a long period of time and a display. In one example, a method includes applying a voltage for brightness inspection to a gate electrode of the vertical organic light emitting transistor to be corrected, measuring a current flowing through a current supply line through which the current is supplied to a source electrode of the vertical organic light emitting transistor by the application of the voltage for brightness inspection to the gate electrode of the vertical organic light emitting transistor to be corrected, and determining a corrected value of the voltage to be applied to the gate electrode of the vertical organic light emitting transistor based on a value of the current and characteristic information of the vertical organic light emitting transistor stored in the memory.
