Definition statement

This subclass covers:

Control of displays using organic electroluminescent display elements arranged in a matrix, wherein each display elements is located together with an active element such as a transistor or a diode, other than the light-emitting one, at the intersection of a scan electrode and a data electrode. The active element has to be enabled by the application of a scan signal to the scan electrode so that the display element receives the data signal.

The figure below is an example of an active matrix. In the figure, active matrix is an individual driving method where light-emitting devices are turned on by each film transistor (TFT), and a matrix is an arrangement of light-emitting devices or TFTs or their combinations.
