Problems solved by technology

[0004] However, adding single-sided adhesive tape or PET film not only increases the cost of materials, but also needs to be assembled separately in separate steps with light-shielding tape and single-sided adhesive tape, which is inefficient and indirectly increases the labor cost of the display device

Embodiment Construction

[0048] The invention breaks the inertial thinking of traditional shading tape design, and cuts the release film of the shading tape at the original place where the single-sided tape needs to be attached. When using, the release film is torn off, and the part that needs to be kept can be broken from the cutting line. , so as to achieve the purpose of saving the cost of single-sided tape and the time of assembling single-sided tape.

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0050] An aspect of the embodiments of the present invention provides a light-shielding adhesive tape. Please refer to Figure 2A , the light-shielding tape 100 includes: a light-shielding tape body 130 and a first release film 110 and a second release film 120 respectively attached to both s...

Abstract

The invention discloses shading adhesive tape, a display device with the shading adhesive tape and a preparation method of the shading adhesive tape. The shading adhesive tape at least comprises an adhesive tape body for shading and a first release film in the thickness detection, wherein the first release film is attached to the first surface of the adhesive tape body. The first release film is provided with one or more cutting lines, reserved parts are defined on the first release film through the cutting lines, and in the process of tearing the first release film away from the adhesive tape body, the reserved parts can be broken from the cutting lines and reserved on the adhesive tape body. By means of the shading adhesive tape, the purposes of reducing the cost of single-sided adhesive tape and shortening the time of assembling single-sided adhesive tape are achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light-shielding tape, a display device using the light-shielding tape and a preparation method thereof. Background technique [0002] In the prior art, the light leakage problem of the backlight module is solved by arranging a light-shielding tape between the backplane of the backlight module and the edge of the lower surface of the display panel. However, the light-shielding tape is often attached to the display panel, which will cause defects of bright and dark spots in front of the backlight module. [0003] In order to solve the above problems, the traditional solution is to add a single-sided tape or PET (Polyethylene terephthalate, polyethylene terephthalate) film on the light-shielding tape at the light entrance of the backlight module, such as figure 1 shown. [0004] However, the addition of single-sided adhesive tape or PET film not only increases the material cost...
