Shading glue film production method

Abstract

The invention relates to a process for preparation of a shading glue film, which provides a process for preparation that centralized light can be assuredly projected on a shading glue film of an outer frame of a display screen, when in use, the invention has more convenient employment, easy pasting and easy tearing, and no remaining trace, which can be attached for a long term. The process for preparation of the shading glue film of the invention firstly has a fist time pasting, and materials such as a separating type film membrane, a double-sided adhesive, and an auxiliary separating type film membrane are respectively arranged on each feeding shaft and are fixed, and then a separating type surface of the separating type film membrane is pasted with the double-sided adhesive, and then the separating type surface of the separating type film membrane and the double-sided adhesive which are pasted are stamped in one time to start a waste discharging procedure, and remainder of an inner frame is torn, products of waste material which is torn are cut off to get a bale packing procedure through a trimming machine and a photoinduction after a second time pasting, a second time stamping, a second time waster discharging procedure. The shading glue film of the invention is convenient for assembling staffs to tear off the shading glue film of the outer frame which is accurately pasted on the periphery of the display screen, and assembling work can be effectively simplified and working efficiency can be improved.

Description

technical field [0001] The invention relates to a light-shielding adhesive film for a liquid crystal display panel, in particular to a method for producing a light-shielding adhesive film for an outer frame of a concentrated liquid crystal display panel light source. Background technique [0002] At present, most high-tech electronic products are developing in the direction of lightness, lightness and shortness. Especially in terms of displays, a large number of LCD liquid crystal displays with active light emitters are used to form screen output and display rich-color images on the liquid crystal display. Since the light source is scattered in the edge area of ​​the liquid crystal display, the light efficiency at the edge of the liquid crystal display becomes lower, making the picture in the edge area darker. At present, a light-shielding film is pasted on the outer frame of the liquid crystal display, and black ink is coated on a layer of film for light-shielding. However,...

Problems solved by technology

At present, a light-shielding film is pasted on the outer frame of the liquid crystal display, and black ink is coated on a layer of film for light-shielding. However, the ink-coating process has the defects of uneven coloring and easy fading, which weakens the light-shielding performance and affects the product. quality
