Abstract (en)
The electroluminescent display device has a lightning or displaying panel having a network of light transmitters disposed in rows and columns, and a network of column electrodes. A voltage generating unit (2) delivers a supply voltage between two output terminals. The resistance of the column transmitter is defined as the resistance of the column electrode to which the transmitter is connected, where the resistance is taken between a supplying point of the electrode and connection point of the transmitter. A compensating unit (3) compensates the differences between the resistances of each column transmitter. An independent claim is also included for a method for controlling image lightning or displaying device.
