Claim 3:
4. A display comprising:
a plurality of vertical organic light emitting transistors;
a data line that supplies a voltage for controlling a gate electrode of the plurality of vertical organic light emitting transistors;
a current supply line that supplies a current to a source electrode of the plurality of vertical organic light emitting transistors;
a first thin film transistor that is connected between the gate electrode of each of the plurality of vertical organic light emitting transistors and the data line and controls voltage supply to the gate electrode of the vertical organic light emitting transistor;
a first gate line that is connected to a gate electrode of the first thin film transistor and controls the first thin film transistor;
a controller that controls a voltage applied to at least the first gate line;
a current measurement portion that measures a current flowing through the current supply line;
a memory that stores characteristic information of each of the plurality of vertical organic light emitting transistors; and
a second thin film transistor that is connected between the source electrode of the vertical organic light emitting transistor and the current supply line and controls current supply to the source electrode of the vertical organic light emitting transistor,
wherein the controller performs control such that a voltage for brightness inspection is applied to the gate electrode of a vertical organic light emitting transistor to be corrected, and the second thin film transistor connected to vertical organic light emitting transistors that are not to be corrected is in an OFF state,
the current measurement portion measures a current flowing through the 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 stores a value of the measured current in the memory, and
the controller determines a corrected value of the voltage to be applied to the gate electrode of the vertical organic light emitting transistor based on the value of the measured current and the characteristic information of the vertical organic light emitting transistor stored in the memory.
