Abstract
A device operating in accordance with the invention receives data respective of an image to be displayed, determines the illumination load requirement for at least one illumination period according to the image data and adjusts the operation of the illumination driver according to the illumination load requirement such that a driving current is maintained between an electrode charging phase and an illumination phase according to the illumination load requirement. The invention seeks to negate the driving electrode inductance between the driving circuit and the load by maintaining an electrical current within the driving electrode between the charging phase and the conductive phase.
Claims20
A method comprising, inducing an electrode current for applying a voltage across and a current through a breakover conduction element, comprising a first current component for charging said voltage across and inducing a second current component anticipatory of said current through.
An apparatus comprising;
- an electrode coupled to a cell having capacitance and a switching characteristic therein, a driving circuit for applying a pulse to said electrode, comprising a first switching circuit for inducing a first current to influence a transition time of said pulse and a second switching circuit for providing a second current to said electrode anticipatory of a current requirement of said switching characteristic.
A device comprising;
- a controller for receiving an input signal and driving an electrical load having first and second loading levels according to said input signal, said controller enabling a first switching circuit coupleable to said electrical load, for applying first and second pulses to said first electrode, and during said first pulse, enabling a second switching circuit according to said first loading level and subsequently, during said second pulse, enabling said second switching circuit according to said second loading level, wherein said first and second loading levels are substantially different.
