Thus, nonfunctioning or out of specification arrays may be identified at an early point in the manufacturing cycle of the display. The strip may be comprised of amorphous silicon which is illuminated during the test in order to reduce the intrinsic resistance of the strip. The strip may also be comprised of a layer of metalization, which layer is removed from the array at the completion of the test.

Abstract: A DC-AC converter circuit for a power supply contains a parallel resonant circuit topology. Accordingly, stray capacitance associated with the converter forms a part of the resonant circuit and assists in setting the resonant frequency thereof. The energy in the stray capacitance which is normally lost is recovered by the resonant circuitry. A coupled inductor (38) is connected in series with primary winding (56, 58) of an output transformer (53) of the converter. The coupled inductor (38) includes a resonating inductor winding (36) and an energy recovery winding (40) which are tightly wound out of phase with one another. A resonating capacitance (64) is connected across the primary windings (56, 58) of the output transformer (53). Energy from the resonant inductor winding (36) is coupled to the recovery winding (40) when the switching elements (66, 68) of the converter are switched on and off. Therefore, energy otherwise dissipated in switching operation is conserved by being returned to its source. Further, the switching elements (66, 68) of the converter are connected in series through diodes (60, 62) to the return line. Consequently the converter is capable of operating either in a buck or boost mode and to switch from one mode of operation to the other.
