  • Patent number: 7358939
    Abstract: An organic light-emitting diode display driver adjusts the display scan period of the current driving the organic light-emitting diodes of a selected row based upon the sum of the display data corresponding to the selected row, thereby removing crosstalk in the OLED display panel. The driver includes an adder for adding the display data corresponding to the selected row and a scan period look-up table storing display scan period values. The scan period look-up table is configured such that it outputs display scan period values substantially proportional or inversely proportional to the sum of the display data to remove bright crosstalk or dark crosstalk, respectively, in the OLED display panel.
