The invention discloses a backlight module, which comprises a backboard, a plastic box, a light guiding plate and at least one optical membrane, wherein two opposite sides of the plastic box are respectively provided with at least one adhesive zone pasted to the backboard, and at least one no-adhesive zone which is not pasted to the backboard; two opposite side surfaces of the light guiding platerespectively form a gap with the no-adhesive zone; in addition, the optical membrane is arranged in a space defined by the light guiding plate and the plastic box. When two opposite sides of the plastic box are stressed, each no-adhesive zone of the plastic box is in contact with the side surface of the light guiding plate, and the optical membrane is spaced.
Description
technical field [0001] The invention relates to a backlight module and an optical film positioning method. Background technique [0002] In the current design of the backlight module, when positioning the optical film, it is necessary to consider the problem of film expansion and assembly tolerance, so there must be a gap between the left and right sides of the film and the plastic frame, and the film must be assembled in the middle to avoid Problems such as bright lines caused by extreme assembly. The conventional design usually uses a jig to position the diaphragm, but limited by the influence of cumulative tolerances and the current design requirements for reducing the reserved gap as much as possible, it is difficult to provide enough space for setting the limit jig, resulting in the optical diaphragm Can't pinpoint it quickly. [0003] The paragraph "Background Technology" is only used to help understand the content of the present invention, so the content disclosed i...
