OPTICAL FILM AND BACKLIGHT MODULE USING SAME

摘要

An optical film and backlight module using the same are provided to lower the manufacturing cost of the backlight module and solve the problem of conventional apparatus. An optical film has properties of: forming dense arrangement of optical condensing on at least one among a first side and second side; having the first side and second side; and containing pyramid configuration having long axis and short axis. The optical condensing structure focuses the light to vertical direction and horizontal direction to the optical film and emits the condensed light.
