PURPOSE: An organic light emitting display device and driving method thereof are provided to reduce power consumption and heat generation by implementing precharging and charge sharing by each data line. CONSTITUTION: A charging line(61) intersects with multiple data lines(DL). Charging voltage(Vpre) is connected to one end of the charging line. A charging switch(57) connects the charging line to the data line. The charging switches are respectively controlled by data line. A charging control part(70) controls the charging switch. The charging control part compares current input data with previous input data. |
