An electroluminescent display formed on a ceramic substrate having a front ceramic surface and a back ceramic surface. The ceramic substrate includes a metal core that provides structural support, electrical ground, and heat dissipation. Electroluminescent cells are mounted on the front ceramic surface and driver circuits for driving the of electroluminescent cells are mounted on the back ceramic surface. The driver circuits are positioned directly behind said electroluminescent cells. Connectors extend through said ceramic substrate and the electroluminescent cells to different driver circuits. By positioning the driver circuits close to the EL cells, the drive lines from the drivers to the EL cells are short which allows for high refresh rates and low resistance losses. Each of the driver circuits can drive one electroluminescent cell or a group of electroluminescent cells. EL display cells coupled to a cermet electrode can also be driven by a field emission device or a low power electron beam.
