Optical composite film for improving flash phenomenon

The utility model discloses an optical composite film for improving the flash phenomenon, the optical composite film for improving the flash phenomenon comprises a prismatic lens 1, a prismatic lens 2, a binder and particles, the prismatic lens 1 comprises a base material 1 and a forming surface, the upper plane of the base material 1 is provided with the forming surface, the cross section of the forming surface is in the shape of triangles which are sequentially distributed in an array mode, and the prism lens 2 comprises a prism lens 3. A prism sheet II is adhered to the lower plane of the base material through a binder, the triangular upper part on the prism sheet II is impregnated in the binder, and particles for preventing flash are dispersed and distributed in the binder, are spherical and have the particle size of 1-2 mu m. By means of the mode, the round particles are dispersed in the binding agent, light rays from bottom to top are scattered through the particles, the problem of flash is solved, the
