ABSTRACT:
Disclosed are an apparatus and a method for compensating for an interlaced-scan type video signal for stably displaying the video signal in the LCD panel. An aft part of 264thdata of a first field and a fore part of 23rddata of a second field are stored in memories. A present video signal is determined whether the present video signal is a first field signal or a second field signal through an equalizing pulse period. If the present video signal is the first field signal, a fore part of 23rddata is copied to the first data field, and if the present video signal is the second field signal, the aft part of the 263rddata is added to the second field data. In case of a PLA-type video signal, first data represent 23rddata, and final data represent 313rddata.
