METHOD OF ERASING PARASITIC CAPACITANCE BY USING FRONT/BACK PORCH PERIOD OF SCAN LINE IN ORGANIC LUMINESCENCE ELECTRO DISPLAY PANEL, IN WHICH TWO TIME RESET OPERATION IS PERFORMED DURING ONE LINE SCANNING PERIOD

摘要

PURPOSE: A method of erasing a parasitic capacitance by using a front/back porch period of a scan line in an organic luminescence electro display panel is provided to prevent the deterioration of the luminance. CONSTITUTION: The method of erasing a parasitic capacitance by using a front/back porch period of a scan line in an organic luminescence electro display panel is characterized in that output signal of each scan line maintains a predetermined front porch period(TFR) after it is converted from a high level to a low level, and maintains a predetermined back porch period(TBK) before it converted from the low level into the high level; making the potential in the predetermined front porch period(TFR) among output signals of the scan line equal to that of the predetermined back porch period(TBK).
