Film pasting method for LED module and display screen

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a method for pasting films of LED modules and a display screen. Background technique [0002] In different application scenarios of LED display screens, different film materials need to be pasted on the surface of LED modules. For example, in order to improve the contrast, a bright black film can be pasted, in order to eliminate glare, a matt film can be pasted, in order to achieve a 3D display effect, a polarizing film that matches the polarized glasses can be pasted. [0003] The different film materials used solve the functional requirements of different application scenarios of LED displays, but the pasting process of the film materials is a complicated problem, because the LED display screen will emit heat when it is working, and the basic materials of the film materials are all Polymer materials such as PET are deformed due to changes in internal stress after b...
