Patent ID: 8049687

Claim:
A method of driving a display device, comprising: simultaneously first-writing a first data signal array of n th frame data signals and a second data signal array of (n−1) th frame data signals on an upper display area and a lower display area of a display panel during a first frame period, respectively, wherein the first frame period includes first and second steps, the first step ranging between a start point and a third quarter of the first frame period, during which the first step three quarters of the first data signal arrays of the nth frame are written onto the upper display area, and three quarters of the second data signal arrays of the (n−1) th frame are written onto the lower display area, the second step ranging between the third quarter and a fourth quarter of the first frame period, during which the second step a residual fourth quarter of the first data signal arrays of n th frame are written onto the upper display area, and a residual fourth quarter of the second data signal arrays of the (n−1) th frame are written onto the lower display area; and simultaneously second-writing a first data signal array of (n+1) th frame data signals and a second data signal array of the n th frame data signals on the upper display area and the lower display area of the display panel during a second frame period, respectively, consecutively to the first-writing to update the first-written upper and lower display areas through the second-writing, wherein the second frame period includes third and fourth steps, the third step ranging between a start point and a first quarter of the second frame period, during which the third step a first quarter of the first data signal arrays of the (n+1) th frame are written onto the upper display area, and a first quarter of the second data signal arrays of the n th frame are written onto the lower display area, the fourth step ranging between the first quarter and a second quarter of the second frame period, during which the fourth step a second quarter of the first data signal arrays of (n+1) th frame are written onto the upper display area, and a second quarter of the second data signal arrays of the n th frame are written onto the lower display area.
