Abstract: A backlight module and a liquid crystal display (LCD) apparatus using the same are disclosed. The backlight module includes a bottom plate and multiple lamps disposed separately over the bottom plate. The bottom plate has multiple lower-reflectivity areas underneath the lamps and multiple higher-reflectivity areas between neighboring lower-reflectivity areas. The LCD apparatus includes such a backlight module and a LCD panel disposed over the lamps.

Abstract: A method for improving backlight uniformity is disclosed in which the two outermost lamps near each of the two sides of the back plate are positioned higher than the other lamps. Hence, the outermost lamps are closer to the scattering plate, thus improving the brightness at the two sides of the LCD panel such that various illumination and the shadows generated in specific regions on the LCD panel are avoided.
