ABSTRACT:
An improved TFEL matrix panel drive technique, for improving the brightness output, which utilizes a voltage wave form applied to the row which possesses a first initial peak voltage region, which when combined with a column voltage, exceeds a predetermined threshold voltage for the emission of luminescence, the first initial peak voltage region being relatively short in duration and higher in voltage, with respect to a secondary extended plateau region which when taken in combination with any column voltage is below the predetermined threshold for emission of luminescence. The technique accomplishes its result by allowing for the application of voltage signals to more than one row at a time however only one row is permitted to possess a first initial peak voltage region at any one given time.
