Structure for positioning optical films on a back light module of display
First Claim
1. A positioning structure of a back light module, comprising:
- an optical film, comprising at least one flange respectively disposed at two corresponding edges thereof, and said flange comprising a neck portion having a narrower width than that of said flange; and
a frame, used to position said optical film, and comprising;
a base containing said flange of said optical film;
a constraining block, protruding from a surface of said base and corresponding to said neck portion of said flange so as to limit displacement of said flange parallel to the surface of said base; and
a bridge, mounted on the top of said base, limiting displacement of said flange perpendicular to the surface of said base, wherein gaps as displacement space when said optical film is heated to deform are retained both between said constraining block and said neck portion of said flange, and between said bridge and said flange.

Abstract
A positioning structure of a back light module has an optical film and a frame, wherein at least one flange is respectively disposed at two corresponding edges of the optical film and the flange has a neck portion. The frame is used to position the optical film and includes base, a constraining block and a bridge, wherein the base is used to contain the flange of the optical film, and the constraining block protrudes from the surface of the base and corresponds to the neck portion of the flange so as to restrict displacement of the flange parallel to the surface of the base, and the bridge is mounted on the top of the base to constrain the displacement of the flange perpendicular to the direction of the surface of the base. In addition, appropriate gaps are retained both between the constraining block and the neck portion of the flange, and between the bridge and the flange such that the optical film can freely extend when it is heated to deform.
