CHANNEL INTERFERENCE COMPENSATION METHOD FOR DISPLAY DEVICE, DATA SIGNAL DRIVING CONTROL APPARATUS AND DISPLAY APPARATUS

摘要

A channel interference compensation method of a display device, a data signal driving control apparatus and the display device are provided to compensate channel interference without increasing the size of a circuit by controlling the length of a discharge period or a maximum amplification period for each scan line. A channel interference compensation method of a display device includes steps of: obtaining pixel data of scan lines(S1~Sm) selected from an external picture memory(200); adding up the obtained pixel data and detecting the compensation time for compensating channel interference generated in the selected scan line by using the sum value; and regulating at least one of the discharge time and maximum amplification time of driving current output to each data line according to the detected compensation time. In the compensation time detecting step, a lookup table storing the compensation time correspondent to the sum value of the pixel data of the scan line is searched by the sum value of the pixel data.
