Abstract
Techniques are described for operating a display comprising an array of emitters arranged in at least one column. Data is shifted through the emitters of the column using a data shifting circuit. The data can be shifted sequentially, one emitter at a time. The data shifting circuit includes storage elements for temporary storage of the data as it is shifted down the column. The data can be stored as a charge on a capacitor, where the capacitor is charged to a particular voltage according to a current from a current mirror. The shifting can be performed in synchronization with scanning of the emitters by a scanning assembly, where the scanning produces an output image for viewing by a user.
