Abstract
A driver includes a plurality of variable resistors each coupled to a corresponding one of the rows of the organic light-emitting diode display panel, generally between Ground (GND) and the cathodes of the OLEDs on the rows. A variable resistor controller in the driver is coupled to the variable resistors, and adjusts the resistance of the variable resistor coupled to the selected row based upon the display data corresponding to the selected row. The variable resistor controller adjusts the resistance of the variable resistor coupled to the selected row to be inversely proportional to the sum of the display data corresponding to the selected row.
