Design considerations for a future electroluminescent TV panel

In a survey of the total systems aspects for a flat-panel electroluminescent display, it is shown that an EL-TV panel is feasible. This is based on the use of address and drive circuitry characterized by a large-area thin-film transistor (TFT) matrix deposited directly onto the back of the EL layer. Low-voltage dc EL would be most desirable, and a new II-VI polycrystalline heterojunction principle (semibarrier injection EL) to accomplish this is proposed. However, existing ac EL can be used, pending some improvements.
