Abstract
An active matrix electroluminescent device that includes a plurality of layers. A rearwardly disposed support layer supports the plurality of layers and an interface circuit. The interface circuit is electrically connected to row and column drivers by a plurality of first electrical lines. The drivers are electrically connected to the plurality of layers so as to enable pixels within the electroluminescent device to be selected. An interface controller is remotely located from the support layer and is electrically connected to the interface circuit by at least one second electrical line so as to indicate which pixels within the device to illuminate. The number of first electrical lines is greater than the number of the at least one second electrical line. In another embodiment of the present invention, the number of lines required to interconnect a passive thin film electroluminescent device with an interface controller can in a similar manner be reduced by including an interface circuit.
