A backlight module has a first side viewing angle luminance LAS1 and a first normal viewing angle luminance LAN1 in the side viewing mode, wherein LAS1/LAN1>50%. The backlight module has a second side viewing angle luminance LAS2 and a second normal viewing angle luminance LAN2 in the narrow viewing mode, wherein LAS2/LAN2<0.5%. The first side angle and the second side angle occur in a slanting direction. The first normal view and the second normal view occur in a normal direction. When executing a side viewing execution step, an upper backlight unit and a lower backlight unit are activated to form the side viewing mode. When executing a narrow viewing execution step, the upper backlight unit is turned off and the lower backlight unit is activated to form the narrow viewing mode. The invention also provides a display device including the backlight module.
A backlight module, capable of switching between a side viewing mode and a narrow viewing mode, wherein in the side viewing mode, the backlight module has a first side luminance LAS1 and a first normal luminance LAN1, wherein LAS1/LAN1>50%, and in the narrow viewing mode, the backlight module has a second side luminance LAS2 and a second normal luminance LAN2, wherein LAS2/LAN2<0.5%, the first side angle and second side angle are in a slanting direction, and the first normal angle and second normal are in a normal direction.
