CONTROL DEVICE FOR LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, METHOD FOR CONTROLLING LIQUID CRYSTAL DISPLAY DEVICE, PROGRAM, AND STORAGE MEDIUM FOR PROGRAM

A liquid crystal driving circuit controls operations of display areas in a liquid crystal display panel based on a plural pieces of divided image data which are prepared by dividing image data for a single screen in accordance with the display areas in the liquid crystal display panel. In response to an luminance signal corresponding to an LED resolution generated by an LED resolution signal generating circuit based on image data for a single screen which is not divided, the LED driving circuit controls operations of LEDs provided in a backlight unit. With the configuration of at least one embodiment, according to a liquid crystal display device including a backlight, in a case where display image data for a single screen is divided into a plural pieces of divided image data for a plurality of areas of a display screen and images to be displayed in the plurality of areas are controlled based on the plural pieces of divided image data, display quality in a border area of the plurality of areas can be improved.
