The stability of ZnS:Mn AC thin film Electroluminescence (ACEFEL)
devices as demonstrated by the brightness-voltage (BV)
characteristics is discussed. Two procedures for improvement of the
stability are demonstrated. The first method is the addition of a
CaS buffer layer to one or both interfaces of the ZnS active phosphor
Alternating-current thin-film electroluminescent (ACTFEL) devices are used in the
formation of pixels in flat panel displays. ACTFEL flat panel displays have many
advantages over other flat panel technologies. Specifically, ACTFEL panels are emissive
displays, they have high brightness, wide viewing angles, and rugged construction.
Although much is already known about...
Development of a suitable thin-film technology has stimulated research in, and production of, a.c. thin film electroluminescent (ACTFEL) devices. The aim of this thesis is to provide a better understanding of the physical processes associated with the device characteristics
of such ACTFEL devices. The unique phenomena exhibited by these devices...
