An active-matrix electroluminescent (AMEL) design tool has been developed for
the simulation of AMEL display devices. The AMEL design tool is a software package
that simulates AMEL device operation using a lumped parameter circuit model. The
lumped parameter circuit model is developed primarily to address AMEL power
dissipation issues. The...
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...
Alternating-current thin-film electroluminescent (ACTFEL) devices are metal-insulator-semiconductorinsulator-
metal (MISIM) structures which emit light under high field, pulsed excitation. One aspect of ACTFEL operation that is not well understood is the aging of such devices with operating time. One of the primary goals of
this thesis is to characterize the kinetics...
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...
Two methods of electro-optically characterizing alternating-current thin-film electroluminescent (ACTFEL) devices are investigated: photo-induced transferred charge (PIQ) and luminescence (PIL), and subthreshold voltage-induced transferred charge (VIQ) techniques. Both techniques provide information related to traps within the phosphor layer. PIQ/PIL experiments monitor the transport of electrons and holes across the phosphor layer...
The purpose of this thesis is to contribute to the understanding of SrS-based alternating-current thin-film electroluminescent (ACTFEL) device operation. Three main accomplishments serving this purpose are presented in this thesis. First, two new methods are developed for estimation of insulator capacitance in ACTFEL devices possessing a large amount of dynamic...
