Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for controlling operations of a liquid crystal display device which includes a liquid crystal display panel and a backlight unit having a plurality of light sources arranged in a matrix manner in a backside of the liquid crystal display panel, said control device comprising: a liquid crystal control section which controls pixels of the liquid crystal display panel in accordance with plural pieces of divided image data, the plural piec…
