Adhesive tape and display device using same

Abstract

The invention relates to an adhesive tape and a display device using the same. The adhesive tape comprises a first sub-adhesive-tape, a second sub-adhesive-tape and a fiber layer, wherein the first sub-adhesive-tape is provided with a first substrate layer, and a first adhesive layer and a second adhesive layer are arranged between the two sides of the first sub-adhesive-tape; the second sub-adhesive-tape is provided with a second substrate layer, and a third adhesive layer and a fourth adhesive layer are arranged between the two sides of the second sub-adhesive-tape; the third adhesive layeris connected with the second adhesive layer, and the fiber layer is provided with an implantation part and an adhesion part; the implantation part is embedded inside the second adhesive layer, and the adhesion part is wrapped around the surface of the second adhesive layer along a first direction, or the implantation part is embedded inside the third adhesive layer, and the adhesion part is wrapped around the surface of the third adhesive layer along the first direction, so that the resistance generated when the first sub-adhesive-tape is torn relative to the second sub-adhesive-tape along the first direction is less than the resistance generated when the first sub-adhesive-tape is torn relative to the second sub-adhesive-tape along the direction different from the first direction.

Description

technical field [0001] The invention relates to an adhesive tape and a display device using the same, in particular to a light-shielding tape and a display device using the light-shielding tape. Background technique [0002] During the assembly process of the liquid crystal display device, a double-sided light-shielding adhesive tape is required to fix the display liquid crystal panel into the casing. Such as Figure 1A As shown, FIG. 1 is an assembly method of a conventional liquid crystal display device 10 , wherein an adhesive tape 12 is located between the casing 13 and the liquid crystal panel 11 to fix the liquid crystal panel 11 to the casing 13 . This tape usually has a strong adhesive to ensure the effectiveness of the fixation. [0003] However, after the liquid crystal display devices are assembled, some liquid crystal display devices will be returned to the factory for rework due to various defects. During heavy work, the liquid crystal panel needs to be separa...

[0003] However, after the LCD devices are assembled, some LCD devices will be returned to the factory for rework due to various defects.

During heavy work, the liquid crystal panel needs to be separated from the casing. For some small-sized liquid crystal panels, because the glass thickness is relatively thin, it is easy to produce fragments when removing this layer of tape, such as Figure 1B As shown, the edge portion of the liquid crystal panel 11 is broken due to the adhesive force of the adhesive tape 12, so that the entire display is scrapped, and the bad cost of the liquid crystal display device is increased.
