Novel FPC two-sided glue adhesion method

Abstract

The invention provides a novel FPC double-sided adhesive cementation method; the novel FPC double-sided adhesive adopts a black-white double-sided adhesive; the black-white double-sided adhesive is used for replacing the common transparent double-sided adhesive for innovation application; the novel FPC double-sided adhesive is adhered on the FPC; then the FPC is adhered on the adhesive frame and a light guide plate, or the FPC double-sided adhesive is firstly adhered on the adhesive frame and the light guide plate, then the FPC is adhered; the release paper on both surfaces of the novel FPC double-sided adhesive are torn and adhered on the corresponding FPC, adhesive frame and the light guide plate so that the lighting effect of the backlight product is improved effectively; the uniformity is improved; the generation of the bright spot is prevented; the manufacturing process of the novel FPC double-sided adhesive is simple, convenient and easy to master; the production cost is reduced to the maximum extent; the novel FPC double-sided adhesive cementation method has great market popularization value.

Description

technical field [0001] The invention relates to a double-sided adhesive bonding method, in particular to a novel FPC double-sided adhesive bonding method that can improve the uniformity of a backlight source product and improve the front effect of the product. Background technique [0002] At present, there is a great demand for ultra-thin backlight products in the market, and the unit price requirements for the products are relatively low, and the prices of LED lights with different thicknesses applied to ultra-thin backlight products also vary by 20% - 40%. , the thinner the LED lamp is, the more expensive it is, so it is necessary to consider using a lamp thicker than the light guide plate in ultra-thin backlight products. [0003] However, in the current backlight products made by the above scheme, because the lamp is 0.05 to 0.1 mm thicker than the light guide plate, all the light cannot enter the light guide plate, and transparent double-sided adhesive is used as the d...

Problems solved by technology

[0003] However, in the current backlight products made by using the above scheme, because the lamp is 0.05 to 0.1 mm thicker than the light guide plate, all the light cannot enter the light guide plate, and transparent double-sided adhesive is used as the double-sided adhesive for sticking FPC. In some cases, the light will directly shine on the enhancement film through the double-sided adhesive tape, forming bright spots, causing light leakage from the lamp port, and poor visual effects of the product. As the market and end users have increasing requirements for the display of backlight modules , will inevitably form a contradiction between cost reduction and quality improvement
