Abstract: A method for controlling printing actions of a print head (1) comprising pumps (10) filled with ink (18), and actuators (16) for generating actuation pulses acting on the ink(18), comprises the step of determining a characteristic frequency of the pumps (10). As the characteristic frequency of the pumps (10) is directly related to the geometry of the pumps (10), the characteristic frequency can be used as an indicator of the state of the pumps (10) and the volume of the ink droplets emitted by the pumps (10). In case a slight change of the characteristic frequency is detected, the actuation pulse is adjusted in order to still meet the requirements regarding the volume of the ink droplets. In case a relatively large change of the characteristic frequency is detected, the printing action of the pump (10) concerned is stopped, and may be taken over by another pump (10).

Abstract: An electroluminescent (EL) display device comprises an array of display pixels, each display pixel comprising an EL display element and a driving circuit. A digital pixel drive signal determines whether the pixel is on or off, and a selected one of a plurality of supply voltages is switched to the EL display element. This device enables a digital drive scheme to be implemented, but the provision of a plurality of different supply voltages enables a grey scale to be implemented without requiring time or area ratio systems to be employed. Alternatively, the device of the invention can allow time or area ratio techniques to be improved.

Abstract: Organic light emitting diodes having a transparent cathode structure are disclosed. The structure comprises a low work function metal in direct contact with the electron transport layer of the OLED covered by a layer of a wide bandgap semiconductor. Calcium is the preferred metal because of its relatively high optical transmissivity for a metal and because of its proven ability to form a good electron injecting contact to organic materials. ZnSe, ZnS or an alloy of these materials are the preferred semiconductors because of their good conductivity parallel to the direction of light emission, their ability to protect the underlying low work function metal and organic films and their transparency to the emitted light. Arrays of these diodes, appropriately wired, can be used to make a self-emissive display. When fabricated on a transparent substrate, such a display is at least partially transparent making it useful for heads-up display applications in airplanes and automobiles. Such a display can also be fabricated on an opaque substrate, such as silicon, in which previously fabricated devices and circuits can be used to drive the display.
