    摘要: The invention relates to a display device comprising a plurality of light emitting elements (1), wherein at least one of the elements has an associated capacitor (C1). The display device comprises pre-charging means (7;8) for generating a pre-charge signal for charging the associated capacitor (C1) at least partly. The pre-charging means (7;8) are adapted for generating a pre-charge signal comprising at least a first pre-charge signal in a first pre-charge stage and a second pre-charge signal in a second pre-charge stage. The pre-charge signal preferably comprises a current pre-charge signal followed by a voltage pre-charge signal. The combined pre-charge signal has the advantage of fast, but accurate pre-charging.

    摘要: The present invention is directed towards a method of scanning lines in a display and towards a display control device for scanning lines in a way which is less trackable by the human eye as well as towards an electronic device including such a display control device. The control device includes a line driving unit (18,20) and a control unit (22), which control unit (22) varies the selection of lines to be scanned and controls the line driving unit (18,20) to scan the selected lines. Selection and scanning is varied in such a way that energy variations caused by the scanning of lines is less trackable by the human eye. In this way bright lines or flickering normally caused by scanning of lines is reduced.

    摘要: A display device has an array of display elements (2) each driven by an input provided on a data conductor (6). These inputs are generated by data conductor addressing circuitry (9) which has a plurality of controllable driver circuits (32,34,40), each for providing an input to an associated data conductor. The number of controllable driver circuits is at least one greater than the number required for providing data to all data conductors. A reference driver circuit (30) is used for calibrating at least one of the controllable driver circuits whilst the other controllable driver circuits provide inputs to the data conductors. This provides a reduction in the spread of driver circuit outputs by calibration of the driver circuits using a reference driver circuit.
