BACKLIGHT SPLIT CONTROL APPARATUS AND BACKLIGHT SPLIT CONTROL METHOD USING THE SAME
First Claim
1. A split control apparatus of a backlight which is divided into a plurality of sections, comprising:
- an image signal processor for calculating a section luminance control value which is a representative luminance value of the section, from an image signal;
a control signal generator for calculating a backlight control value which is a control signal of the backlight, by correcting a section luminance calculation value using a difference between the section luminance control value and the section luminance calculation value acquired from a section luminance distribution value of a light source of the backlight; and
an image signal regulator for adjusting the image signal using the backlight control value.
