Abstract
Various examples are provided related to driving a light emitting display in which variations in image quality and brightness can be suppressed despite long-term use, without adding a complicated circuit configuration. In one example, a method includes applying a voltage based on image data to be displayed to a gate electrode of a vertical organic light emitting transistor and applying a voltage, having a polarity opposite to that of the voltage applied to the gate electrode of the vertical organic light emitting transistor, to the gate electrode of the vertical organic light emitting transistor based on a value of a voltage being applied to a source electrode of the vertical organic light emitting transistor.

A method of driving a light emitting display comprising:
- a step (A) of applying a voltage based on image data to be displayed to a gate electrode of a vertical organic light emitting transistor including source, drain, and gate electrodes arranged in one direction;
- and
- a step (B) of, after the step (A), applying a voltage, having a polarity opposite to that of the voltage applied to the gate electrode of the vertical organic light emitting transistor in the step (A), to the gate electrode of the vertical organic light emitting transistor based on a value of a voltage being applied to a source electrode of the vertical organic light emitting transistor.
A display comprising:
- a plurality of vertical organic light emitting transistors including source, drain, and gate electrodes arranged in one direction;
- and
- a controller for controlling driving of a vertical organic light emitting transistor, wherein the controller is configured to display an image by:
- (A) applying a voltage based on image data to be displayed to a gate electrode of the vertical organic light emitting transistor of the plurality of vertical organic light emitting transistors;
- and
- (B) applying a voltage, having a polarity opposite to that of the voltage applied to the gate electrode of the vertical organic light emitting transistor in (A), to the gate electrode of the vertical organic light emitting transistor based on a value of a voltage being applied to a source electrode of the vertical organic light emitting transistor.
