Abstract
Display panel driving circuits and methods of driving a display panel with first video data and second video data include determining a starting position and a stopping position of the first video data if the first video data is window data and reducing the size of the first video data if the first video data is full screen data. Alternating lines of a first portion of the display panel and a second portion of the display panel are driven with the reduced size first video data and the second video data so as to display the reduced size first video data in the first portion of the display panel and the second video data in the second portion of the display panel if the first video data is full screen data. Lines of a portion of the display panel corresponding to the starting position and the stopping position are driven with the first video data and remaining portions of the display panel are sequentially driven with the second video data so as to display the first video data in the portion of the display panel corresponding to the starting position and the stopping position and the second video data in the remaining portions of the display panel. Subcombinations are also provided.
