Abstract
The present invention provides an edge-lit backlight module containing 2n+1 sequentially and equally separated backlight partitions where the 2n+1 backlight partitions are lit or turned off individually under a time-sequence control; a LCD panel scanned by the edge-lit backlight module is correspondingly separated into 2n+1 display partitions; the signal to the LCD panel is loaded into the LCD panel frame by frame and display partition by display partition under a time-sequence control; the time sequences to the signal to the LCD panel and the signal to the backlight partitions are controlled so that, whenever the signal loaded into the 2n+1 display partitions of the LCD panel constitutes a complete frame, the n+1 backlight partition in the middle of the edge-lit backlight module is always lit. The present invention also provides a scanning method of an edge-lit backlight module.
