Abstract

The invention provides a backlight module and a displayer. The displayer comprises the backlight module and a liquid crystal panel, wherein the liquid crystal panel is stacked on the backlight module. The backlight module comprises shading adhesive, a rubber frame, a reflecting sheet, a light guide plate and an optical membrane, wherein the reflecting sheet, the light guide plate and the optical membrane are stacked sequentially; the reflecting sheet, the light guide plate and the optical membrane are surrounded by the rubber frame; the shading adhesive comprises a first segment and a second segment connected to the first segment, the first segment is double faced adhesive tape, the second segment is single faced adhesive tape, the first segment adheres to the rubber frame and the reflecting sheet, the second segment partially adheres to the end face of the rubber frame, and the other part of the second segment stretches out of the backlight module and adheres to the end face of the liquid crystal panel. Shading colloid thickness can be controlled by the shading adhesive, and therefore the technical effect of narrow bezel is achieved.

Description

technical field [0001] The invention relates to the technical field of display equipment, in particular to a backlight module and a display. Background technique [0002] With the rapid development of liquid crystal display technology and the increasing demand of users for display devices, electronic products with narrow frame display effects are more and more popular among users, especially mobile display products such as TVs, computers and mobile phones. [0003] At present, for liquid crystal display technology with backlight, the narrow frame will increase the risk of light leakage at the edge. Therefore, in the process of narrow frame, a dispensing process will be added to effectively fix the various components and prevent light leakage at the edge of the display, thereby improving the display of the display image. Effect. However, the thickness of the liquid glue used in the dispensing process cannot be precisely controlled, which will seriously affect the technical e...
