Abstract

The invention discloses a packaging adhesive, a backlight module and a display device. The packaging adhesive comprises a first adhesive tape and a second adhesive tape, wherein the first adhesive tape and the second adhesive tape are arranged in an overlapped manner; the thicknesses of the first adhesive tape and the second adhesive tape are equal; the first adhesive tape comprises a first substrate and two first adhesive surfaces distributed on two sides of the first substrate; the second adhesive tape comprises a second substrate and two second adhesive surfaces; the first adhesive tape is arranged on one side, far away from the second adhesive surface, of the second adhesive tape. The backlight module and a display panel are connected through the packaging adhesive, the problems that the backlight module has wrinkles and light leakage can be solved, furthermore the quality of a display is improved, and the pass percent of the display is increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and in particular, relates to an encapsulant, a backlight module and a display device. Background technique [0002] Liquid crystal display (LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. Since the liquid crystal display is a non-luminescent display device, it needs a backlight module to achieve the display function. The backlight module is composed of a light source, a light guide plate, an optical film, a plastic frame, etc., and provides sufficient brightness and evenly distributed light sources for the display panel, so that the display panel can display images normally. Among them, the frame sticker structure used to connect the backlight module and the display panel has two structures: integral and segmented, to realize the connectio...
