The present invention relates to an inkjet print head () comprising at least one nozzle chamber (), having a nozzle aperture () defined in one wall thereof for the ejection of printing fluid out of said aperture (), and a printing fluid supply channel interconnected with said nozzle chamber (). A printing fluid droplet tail release guide arrangement () is arranged at a predetermined position at an edge of a circumference of said aperture (). The present invention further relates to a method for increasing droplet placement accuracy in an inkjet print head having at least one nozzle chamber with a nozzle aperture defined in one wall thereof for the ejection of printing fluid out of said aperture. The method comprises the step of providing a printing fluid droplet tail release guide arrangement at a predetermined position at an edge of a circumference of said aperture.

Increased droplet placement accuracy in inkjet printing

An electric device includes at least one organic diode and a driver for driving the diode in at least a light sensing state. A pre-pulse generator is provided for applying one or more electrical pulses to the diode prior to drive the diode in the light sensing state. The pulses include a positive electric pre-pulse and a negative pre-pulse.

The invention provides a tool to select reliable organic LED devices, where the risk for failure before the end of its lifetime is low. This tool comprises the steps of:

Organic electroluminescent device

The electronic device ( ) has a layer ( ) of a material comprising a first and a second element. This material has an amorphous and a crystalline state. A transition from the amorphous to the crystalline state can be effected by heating of the material to above a crystallization temperature, for example with a laser. As a result, the layer ( ) has a first electrically conducting areas ( ), comprising the material in the crystalline state, which are insulated from each other by the first electrically insulating area ( ), comprising the material in the amorphous state. The layer ( ) may be present as an interconnect layer, but also as a covering layer. Preferably, the material is aluminum-germanium. In the method of patterning a layer ( ), electrically conductive areas of the layer can be strengthened by electroplating.
