(54) LIQUID CRYSTAL PANEL DRIVE DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD, DRIVE CONDITION SETTING PROGRAM, AND TELEVISION RECEIVER


(57) A liquid crystal panel driving apparatus which sequentially receives pieces (1, 2 ...) of video data for one data signal line, (i) prepares a data string by sorting, in order of outputting, a plurality of pieces of video data inputted in a predetermined period while adding a piece of dummy data (D) to a predetermined position, (ii) assigns one horizontal scanning period (HtotalY) to an output of a piece of video data while assigning a dummy scanning period (DtotalY) to an output of a piece of dummy data, and (iii) sets one horizontal scanning period (HtotalY) shorter than an interval (HtotalX) of inputting of pieces of video data. This makes it possible to suppress an increase in vertical display period even though a piece of dummy data is added to inputted video data while a dummy scanning period is assigned thereto.
