Problems solved by technology
Since the square-shaped structure is usually formed by one-piece molding, the scrap rate of raw materials is high and the manufacturing cost is increased; moreover, such a closed square-shaped structure is not conducive to the passage of destructive experiments, and the product is exposed to high temperature and high humidity. Or low temperature environment is prone to various problems; more importantly, such a closed word-shaped structure is not conducive to the adjustment of the display effect of the backlight and the processing of the image consistency

Embodiment Construction
[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] as attached figure 2 As shown, the light-shielding glue splicing structure of the present invention has a rectangular shape and is formed by pasting and splicing four light-shielding tapes, including a first light-shielding tape 1 at the light source end, a second light-shielding tape 3 opposite to the first light-shielding tape, and two The third light-shielding tape 2 and the fourth light-shielding tape 4 on the side, each tape is spliced together by its own adhesive bonding, and the bonding gap between each tape (that is, the bonding distance between each tape) is controlled within 0.2mm Inside.
[0018] Because the existing light-shielding tapes mainly include black light-shielding glue (that is, the upper and lower sides of the tape are black) and black and white light-shielding glue (that is, the side of the tape that is fix...

The invention discloses a shading glue splicing structure which is in a rectangular shape and comprises a first piece of shading tape, a second piece of shading tape, a third piece of shading tape and a fourth piece of shading tape, wherein the first piece of shading tape is located at a light source end, the second piece of shading tape is opposite to the first piece of shading tape, the third piece of shading tape and the fourth piece of shading tape are located on the two sides, all the pieces of tape are bonded and spliced together through viscidity of the tape, and the first piece of shading tape, the second piece of shading tape, the third piece of shading tape and the fourth piece of shading tape can be the same or different from one another. The shading glue splicing structure is simple in splicing mode and low in raw material rejection rate, and the manufacturing cost can be saved by 20% or more; besides, different glue strips are mixed for use, the proportion of light injection can be effectively raised, and the light utilization rate is effectively raised so that the brightness of the backlight module can be improved by 3-5%; besides, by means of the shading splicing structure, the direction of emitted light rays can be more uniform, and thus the uniformity of the brightness of the backlight module is effectively improved.
Description
technical field [0001] The invention relates to a backlight source component of a liquid crystal display module, in particular to a light-shielding glue splicing structure. Background technique [0002] With the popularity of terminal electronic products such as mobile phones and tablet computers and the improvement of liquid crystal display manufacturing technology, the requirements for backlight sources of liquid crystal display modules (Liquid Crystal Display Module, LCM) are also getting higher and higher. As an important part of the backlight assembly, the light-shielding tape is usually pasted on the outer frame of the display screen to achieve a light-shielding effect. Currently, if figure 1 As shown, in the industry, the structure of the light-shielding glue in the backlight assembly is mostly a closed word-shaped structure. Since the square-shaped structure is usually formed by one-piece molding, the scrap rate of raw materials is high and the manufacturing cost i...
