Abstract

The processing effects of polyvinyl-butyrol (PVB)-based binding organics (PBBO) on the characteristics of the ZnS:Cu electroluminescent (EL) devices are discussed. The characteristics of the EL devices fabricated using the PBBO are compared with those of devices fabricated using a membrane switch composition (MSC). It is demonstrated that the performance of the PBBO be comparable with the MSC. The brightness and the output current of devices using PBBO at 100 V and 400 Hz are 55 cd/m2 and 2.2 mA, respectively. The reliability test performed under the harsh environment (333 K and 90% RH) exhibits the life time (time at the half of the original brightness) of device longer than 140 hr.
