Abstract
A driving architecture for a matrix addressed TFEL display includes upper and lower data electrode arrays divided by a narrow gap and scanning electrodes arranged in complementary pairs one for each array of data electrodes. The data electrodes are charged at a rate which minimizes the power loss in the resistive component of the data electrode circuitry. The top and bottom data electrode arrays may be driven simultaneously, thereby decreasing the time needed to scan the panel, thus permitting more electrodes and larger screens. The split-screen array provides shorter data electrodes which take less time to charge, thus permitting use of energy-saving techniques which require a slower charging rate.
