Abstract
An optical film structure of a backlight module is disclosed. The backlight module comprises a frame, a reflective board, a light guide plate, an optical film and a light source unit. A lug is disposed at the side of the optical film for aligning with the rabbet. The peripheral of the optical film is printed with masking tape, and a concave arc is disposed at the masking tape of the lug correspondingly. The concave arc is used to reduce the dark band phenomenon generated by coating masking tape on the lug of the optical film, enabling the backlight module to output light source with even and high brightness so as to enhance the overall light extraction efficiency.
