The invention provides a film pasting method for an LED module. The film pasting method comprises the following steps of material selecting, specifically, a toughened glass sheet, coiled OCA optical cement, a coiled film material and the LED module are prepared; antireflection film plating, specifically, the toughened glass sheet is placed in a vacuum environment, and an antireflection film is plated on the top surface and/or the bottom surface of the toughened glass sheet by adopting a vacuum evaporation method; film pasting, specifically, the film material is pasted to the bottom surface ofthe toughened glass sheet plated with the antireflection film through the OCA optical cement; and fitting, specifically, the toughened glass sheet pasted with the film material is fitted to the surface of the LED module through the OCA optical cement. According to the film pasting method for the LED module, the film material is attached between the toughened glass sheet and the LED module, and because the toughened glass sheet applies downward pressure on the LED module, the film material can be made not to generate the problem of film material bulging or edge corner warping in the packaging,transporting and working processes; and by means of the manner that vacuum antireflection film plating is performed on the surface of the toughened glass sheet, on the one hand, the transmittance of amask can be improved, on the other hand, dazzling light generated by the surface of the mask by external light rays can be avoided, and the visual experience of audiences is improved.
