Abstract:

The inorganic high-luminosity electroluminescent (EL) panel used in this study is a distributed-type EL panel, which can be produced using a printing technique. We obtained a panel with a high luminosity of 7940 cd/m² at 6 kHz. In addition, we believed that the panel temperature and luminosity of this panel were closely related. Therefore, we considered the relationship between the temperature change in the dielectric layer and the luminosity since this relationship is responsible for the supply of electric charge to the phosphor layer. A change in the amount of electric charge by heating in a high-voltage domain originates at the Curie point of BaTiO₃ ferroelectric particles. This indicates that the influence of BaTiO₃ was strong.
