<P>PROBLEM TO BE SOLVED: To solve a problem that, in an LED light source module capable of backlight scanning, deviation in brightness caused by individual differences in such as an LED and a light guiding body occurs prominently in every light source block when particularly thinned. <P>SOLUTION: The LED light source module comprises light source blocks 1 to N which can be individually lighted. In a backlight (BL) scan signal arithmetic device, BL scan signals 1 to N synchronized with video signals are transmitted to LED rows to perform BL scan. Based on a correction value written in advance in EEPROM in a production process, lighting periods of the BL scan signals 1 to N are individually corrected, and the deviation in the brightness of light source blocks 1 to N is made adjustable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
