Abstract:
1. A driving method for reducing image sticking associated with images of a liquid crystal display, the liquid crystal display comprising a plurality of data lines, a plurality of scan lines, and a plurality of pixel areas, one end of each of the plurality of the pixel areas being connected to a common voltage, the driving method comprising: according to a first data-to-voltage relation, converting a first data to a first voltage and a second voltage; according to a second data-to-voltage relation, converting a second data to a third voltage and a fourth voltage; in a first half of a period of time, turning on a first scan line of the plurality of scan lines; in a first half of a period of time, applying the first voltage to a first corresponding pixel area of the plurality of pixel areas; in a second half of the period of time, turning on the first scan line of the plurality of scan lines; in the second half of the period of time, applying the second voltage to the first corresponding pixel area of the plurality of pixel areas; in the first half of the period of time, turning on a second scan line of the plurality of scan lines; in the first half of the period of time, applying the third voltage to a second corresponding pixel area of the plurality of pixel areas; in the second half of the period of time, turning on a second scan line of the plurality of scan lines; and in the second half of the period of time, applying the fourth voltage to the second corresponding pixel area of the plurality of pixel area; wherein the sum of the difference between the first voltage and the common voltage and the difference between the second voltage and the common voltage is different from the sum of the difference between the third voltage and the common voltage and the difference between the fourth voltage and the common voltage.
