Abstract

The invention discloses a supernarrow-bezel light shielding adhesive tape, a light shielding double-side adhesive tape and a preparation method of the light shielding double-side adhesive tape. The light shielding adhesive tape comprises a substrate layer, a first adhesive layer and a second adhesive layer, wherein the first adhesive layer and the second adhesive layer are respectively arranged at both sides of the substrate layer, and adopt the same or different adhesives; each adhesive comprises fluorescent powder; the light shielding adhesive tape is adhered with a heavy release film and a light release film, so as to obtain the light shielding double-side adhesive tape for preparation. By adopting the type, the supernarrow-bezel light shielding adhesive tape, the light shielding double-side adhesive tape and the preparation method of the light shielding double-side adhesive tape have the advantage that one type of nanoparticles with light source absorbing function is added into the high-property adhesive, and the PET (polyethylene terephthalate) substrate with the light shielding effect is used for coating, so that the prepared light shielding adhesive tape can effectively fix a back light module and a liquid crystal display screen, effectively absorb light rays entering the adhesive layer, and effectively improve the screen display effect.

Description

technical field [0001] The invention relates to an ultra-narrow frame light-shielding tape, a light-shielding double-sided tape and a preparation method thereof. Background technique [0002] A backlight module generally includes several parts such as a bracket, a reflector, a light guide plate, and an optical film. Generally speaking, in the assembly of LCD panels and backlight modules on the market, light-shielding tapes are often used to attach the edges of the LCD panel and the backlight module, so that the displacement between the LCD panel and the backlight module is not easy to occur, thereby preventing the liquid crystal display panel. Friction occurs between the backlight module and the optical film of the backlight module to avoid scratching, so as to ensure the display quality of the liquid crystal display panel. In addition, the shading tape can also block excess light emitted from the LCD panel to prevent light leakage. [0003] Liquid Crystal Display (LCD) ha...
