Can improve backlight unit who warp light leak

The utility model provides a can improve backlight unit who warp light leak, include lower iron frame, glue the frame, go up chase, optics diaphragm and FOG, still include a plurality of magnetic sheets, the mounting groove that lower iron frame has bottom surface, side and is enclosed by this bottom surface and side, it sets up in the mounting groove to glue the frame cooperation, the optics diaphragm sets up in lower iron frame's bottom surface, gluing the frame and having the step face, FOG sets up on the step face, and FOG is on a parallel with the optics diaphragm, the position that is close to FOG at the top surface of gluing the frame sets up the magnetic sheet, the top surface of going up the chase supports the top surface of FOG, magnetic sheet, gluey frame, the side knot of going up the chase links in lower iron frame's side. The beneficial effects of the utility model are that: add the magnetic sheet, adsorb by the magnetic sheet and go up the chase top surface to chase and FOG's cooperation positi
