A method and apparatus for providing error voltage compensation in a flat panel display. Voltage errors in a column driver for a flat panel display are compensated for by first measuring the voltage level at each column during a known signal level period and comparing it against a known or reference value. This voltage error signal is then stored in an error memory according to column location. During normal operation of the flat panel display, the memory is accessed every time a particular column is scanned. The error voltage is retrieved and added to the raw video signal in order to remove any voltage offset which is introduced in the column driver electronics. This error voltage compensation substance eliminates any streaking which may appear on a display screen.
