Definition statement

This subclass covers:

Control of displays using organic electroluminescent display elements arranged in a matrix together with active elements, wherein each active element enables a driving current flowing through a display element corresponding to a data current supplied to a data electrode, which is supplied when the active element is activated by a scan signal supplied to a scan electrode, e.g. by a current mirror having the data current flowing through the data electrode as an input current, and the driving current flowing through the display element as an output current.

The figure below is an example of data current signal supplied to the data line DL and flowing through the input part PM2 of a current mirror circuit, which controls the driving current flowing through the output part PM1 of the current mirror circuit and the organic electroluminescent display element.
