An electro-optically active organic diode has anode and cathode electrodes, an electro-optically active organic layer between the electrodes, and a charge carrier organic layer between the electro-optically active organic layer and the cathode electrode layer. The charge carrier organic layer is formed of a highly doped organic semiconductor material. A short protection layer is arranged between the cathode electrode layer and the charge carrier organic layer. The short protection layer is formed of an inorganic semiconductor material.

Highly doped electro-optically active organic diode with short protection layer

A device comprising a first transparent and electrically conductive layer (), a second electrically conductive layer (), and a functional layer () comprising at least one organic layer, sandwiched between said first and second conductive layers and to form a functional organic stack. At least one via () is arranged to electrically interconnect said first layer () and at least one segment () of said second layer (), the segment being electrically insulated from the reminder of the second layer. The present invention makes it possible to uniformly supply the first transparent layer with electrical power. The vias and segments are preferably formed by laser applied through the transparent conductive layer.

Organic based device and method for manufacture thereof

In a display device comprising a first substrate having at least one transparent, first picture electrode of a first material, a second substrate comprising at least one second picture electrode of a second material which, jointly with the picture electrode on the first substrate and an intermediate opto-electronic material, defines a pixel, and means for supplying electric voltages to the picture electrodes, the work function between the two picture electrodes is decreased in that at least one of the picture electrodes is coated with at least one layer of conducting material, or a layer of a material comprising a dipole.
