Abstract
A backlight module comprises an upper and a lower backlight unit. The upper unit includes an upper light source and a substantially rectangular upper light guide plate with a first side edge along a first axis and a second side edge along a second axis which is non-parallel to the first axis. The upper light source is positioned adjacent to the second side edge and extends along the second axis, directing light primarily along the first axis within the light guide plate. 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.
