Abstract

The invention discloses a backlight module and a manufacturing method thereof, a displayer module and annular light shading adhesive tape and belongs to the technical field of liquid crystal display. The backlight module comprises the annular light shading adhesive tape and a backlight source. The annular light shading adhesive tape is attached to the light-out side of the backlight source, and notches are formed in at least one set of opposite corners in the four corners of the annular light shading adhesive tape in order to expose the corners, corresponding to the notches, of the backlight source. The notches are formed in at least one set of opposite corners in the four corners of the annular light shading adhesive tape in the backlight module, when the annular light shading adhesive tape and the backlight source deviate in the attachment process, the corners, corresponding to the notches, in the backlight source can be exposed, and therefore alignment of a display panel and the backlight module is not affected. The backlight module and the manufacturing method thereof, the displayer module and the annular light shading adhesive tape are used for displaying images.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a manufacturing method thereof, a display module and an annular light-shielding adhesive tape. Background technique [0002] A liquid crystal display device is a display device with a backlight module as a light source and a liquid crystal display panel as a display device. The luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display. With the development of liquid crystal display technology, liquid crystal display panels are developing towards ultra-thin and narrow bezels, and the corresponding backlight modules also need to have narrower bezels, thus producing backlight modules without barrier walls. As an indispensable part of the backlight module, the light-shielding glue can bond the display panel and the backlight in the backlight module to achieve the effect of light-shielding. [00...
