Abstract
In the present invention a matrix array of organic electroluminescent storage display elements along with row and column selection circuitry are used to select the particular display elements within the matrix to be illuminated. Interposed between the column and row selection electronics are a plurality of memory cells receiving as inputs bit values that correspond to the desired intensity requested from a display element. The memory cells output activation signals which drive corresponding MOS switches each of which in turn is parallel connected as part of a current driver source feeding a single display element. Activation of one or more of the MOS switches provides a controlled amount of current to be applied to the display element to in turn provide a related amount of light from the display element.
