Backlight Module and LCD Device

摘要

The present invention proposes an LCD device having a backlight module. The backlight module includes a light guide plate, a first light source unit set up in a corner of a first light-in side of the light guide plate, and a second light source unit set up in a corner of a second light-in side of the light guide plate. The first light-in side is set up in opposition to the second light-in side, and the corner of the second light-in side is in diagonal to the corner of the first light-in side. The present invention provides a backlight module and an LCD device in which light enters the light guide plate in a corner. The entering light mix uniformly in the LGP without dark area, and the number of LED along with expense and energy consumption are reduced compared to that of a single short light-in side backlight module.
