ABSTRACT:
A display is arranged in rows and columns with a current source for each column instead of a current source in each display cell. By omitting the current source from the cell, smaller display cell geometries are achieved. In a display where one row is selected at a time, the display of the present invention with smaller circuitry achieves performance identical to the prior art. Application is made to flat panel displays generally including field emission displays, liquid crystal displays, and integrated light emitting diode array displays.
