Embodiment

[0016] Such as figure 1 , 2 As shown, the present invention is an anti-light leakage tape for a narrow frame backlight module, comprising a panel edge-wrapping tape 1 having an adhesive surface and an adhesive-free outer surface 1-2 and having a third adhesive surface 2-1, a fourth adhesive surface The panel fixing tape 2 of the adhesive surface 2-2, the panel fixing tape 2 is bonded to the adhesive surface of the panel edge tape 1, and the adhesive surface of the panel edge tape 1 is divided into two sub-surfaces, that is, the first adhesive surface 1-1 And the second glue surface 1-3, the first glue surface 1-1 and the third glue surface 2-1 form a bent glue surface, the second glue surface 1-3 and the fourth glue surface 2-2 form another bend Fold the plastic surface. The shape and size of the panel edge-wrapping tape 1 and the panel fixing tape 2 refer to the shape and size of the existing panel edge-wrapping tape and panel fixing tape. In this embodiment, the bending a...

Abstract

The invention discloses a light leakage prevention adhesive tape for a narrow-frame backlight module. The adhesive tape comprises a panel edge covering adhesive tape body with an adhesive face and a panel fixing adhesive tape body with two adhesive faces, the panel fixing adhesive tape body is arranged on the adhesive face of the panel edge covering adhesive tape body to divide the adhesive face of the panel edge covering adhesive tape body into two sub-adhesive faces, and the two sub-adhesive faces and the two adhesive faces of the panel fixing adhesive tape body form two bent adhesive faces.The adhesive tape has the advantages that the problems of module line missing and side edge bright line abnormity are solved, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of bonding products, and in particular relates to a light-leakage-proof adhesive tape for a narrow frame backlight module. Background technique [0002] With the technological breakthroughs in the liquid crystal display industry and the promotion of market differentiation and diversified needs, more and more light-weight and narrow-frame backlight module products have been designed and developed, and the products are widely used. In ultra-narrow bezel backlight products, the adhesive tape that is pasted and fixed to the panel is difficult to attach due to its narrow width. On the one hand, the operator is prone to the problem of tape offset when attaching it, which leads to poor module line loss; on the other hand The tape attachment tolerance is difficult to control, and the product is prone to abnormal bright lines on the side edges; in addition, the original panel fixing tape and the panel edge protection...
