Abstract
An electroluminescent display and method of fabricating the same is described in which an active driver panel (14) is integrated with a processed display panel (12) using a unique application of semiconductor wafer technology. A microelectronic driver circuit (32) and back electrode (34) are fabricated on a semiconductor wafer (30) to provide a panel for driving the display. Multiple driver circuits (32) and respective back electrodes (34) may be arranged on the wafer to form an active-matrix electroluminescent display. The display panel (12) includes a front electrode (18) and an adjacent phosphor panel (20) for illuminating the display. The driver panel (14) is adhered to the display panel (12) using either an indium bump connection or a thermal bond, which provide both mechanical and electrical coupling between the back electrodes (34) and the phosphor panel (20). Exposure of the active devices on the driver panel to destructive high processing temperatures inherent in display panel processing is avoided.
