Abstract: An integrated drive circuit for multi-segment electroluminescent displays is provided. During a charging phase, the electroluminescent segments are charged by a common charge circuit, and partially discharged using separate discharge circuits associated with individual electroluminescent segments. A controller provides essentially independent control over the respective discharge circuits so, by the end of the charging phase, the EL segments can be charged to correspondingly different final voltages. Then during a discharging phase following the charging phase, the electroluminescent segments are completely discharged, thereby emitting an intensity of light that varies roughly in proportion to the final accumulated voltage. The controller can be pre-programmed with a spatial-temporal light pattern so that, using the disclosed integrated drive circuit, the electroluminescent display can be operated to generate rudimentary animations.
