ABSTRACT:
A direct type backlight module comprises a bezel, a reflection sheet, a light source, a diffusion plate, and a supporting unit. The light source is positioned between the bezel and the diffusion plate, and the reflection sheet is positioned on the upper surface of the bezel. The supporting element is fixed within the bezel to support the diffusion plate upwardly. The bezel further comprises a fixing hole and a button hole for fixing the supporting element. The supporting unit comprises a planar plate, a cone, a jammed plug, and a fixing button. The cone is positioned upon the planar plate to erect between the planar plate and diffusion plate. The top of the cone contacts with the diffusion plate. The jammed plug connects to the bottom surface of the planar plate by passing through the bezel via the fixing hole. The fixing button connects to the bottom surface of the planar plate, but distances the jammed plug by a fix distance, and inserts through the button hole of the bezel.
