Electroluminescent display

摘要

A driver circuit drives an electroluminescent display ( 1 ) which comprises a matrix of display pixels ( 10 ) associated with intersections of data electrodes ( 12 ) and select electrodes ( 11 ). The driver circuit comprises a select driver ( 2 ) which supplies a select signal (VS) comprising non-overlapping select pulses (VSP) with a predetermined repetition frequency to a selected one ( 11 ') of the select electrodes ( 11 ). The data driver ( 3 ) supplies data signals (DS) comprising data pulses (DSP) with the same predetermined repetition frequency to the data electrodes ( 12 ). The data pulses (DSP) occur during the select pulses (VSP) for data electrodes ( 12 ) of which associated pixels ( 10 ) should not produce light. The data pulses (DSP) occur in-between the select pulses (VSP) for data electrodes ( 12 ) of which associated pixels ( 10 ) should produce light.
