Image display device

An image display device comprising a timing controller, wherein the timing controller comprises:

• a first memory;
• a first line buffer having a first line data of a second frame is buffered therein, the second frame is generated later than a first frame;
• a second line buffer, wherein first compressed data is buffered therein;
• a third line buffer;
• an image processing unit receiving second line data of the second frame that is currently entered the timing controller and, retrieving the first line buffer for the first line data of the second frame to generate second compressed data to be stored in the first memory;
• an image reverse processing unit retrieving the first compressed data from the second line buffer to estimate first line data and second line data of the first frame;
• a motion detector comparing the first and second compressed data to generate a control signal;
• an overdrive unit generating interleaving data of a first line according to the estimated first line data of the first frame and the buffered first line data of the second frame, and generating interleaving data of a second line according to the estimated second line data of the first frame and the currently entered second line data of the second frame;
• a first multiplexer receiving the interleaving data of the first line and the buffered first line data of the second frame, and outputting the interleaving data of the first line or the buffered first line data of the second frame to form second line data of an interleaving frame according to the control signal;
• and
• a second multiplexer receiving the interleaving data of the second line and the currently entered second line data of the second frame, and sending the interleaving data of the second line or the currently entered second line data of the second frame to the third line buffer according to the control signal.
