ABSTRACT:
The present invention relates to a display, and more particularly, to circuit for driving a display of a low power consumption. For the purpose, the circuit includes a light emitting display of current driven type having a plurality of column electrode lines arranged in a column direction, a plurality of row electrode lines arranged perpendicular to the column electrode lines, and a matrix of pixels at crossing points of the column electrode lines and the row electrode lines, a power source part, a column driving circuit connected to the column electrode lines formed in the column direction for supplying/discharging a current to/from the column electrode lines, for driving the light emitting display of current driven type, and an electric transformer for, when the current supplied to the column electrode lines is discharged, recovering the current discharged from the column electrode lines and re-supplying a recovered current to the power source part.
