Patent ID: 7604390

Claim:
A supporting structure applied to a backlight module, the backlight module comprising at least a plurality of optical sheets, the supporting structure comprising: a fixing component with a through-hole and two openings; and a supporting component, comprising: a supporting pin having a top end and a bottom end, the top end for supporting the optical sheets; an elongated block having a width and a length that is greater than the width, the length of the block defining a longitudinal direction of the block, the block being disposed at the bottom end; a plate disposed on the supporting pin and being disposed above the block and separated thereby by a narrowed neck portion; and two protrusions disposed at two opposite sides and directly on a bottom of the plate and facing the bottom end, the protrusions corresponding to the respective openings, an angle being defined between a direction connecting the protrusions and the longitudinal direction of the block, and the angle being larger than zero degrees; wherein after the block goes through the through-hole and is rotated by the angle, the plate presses against an upper surface of the fixing component the block presses against a lower surface of the fixing component, and the protrusions engage in the corresponding openings for positioning the supporting component, so as to fix the supporting component onto the fixing component.
