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
layer....
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...
The accomplishments presented in this thesis are the development of three models
for simulation of space charge generation in the phosphor layer of alternating current
thin-film electroluminescent (ACTFEL) devices and the results from simulation
of these models. First, a single sheet charge model is developed and simulated.
The single sheet...
