The bonding technology in the backlight industry is black-and-white light-shielding tape. Black-and-white double-sided tape is mainly used on backlights to fix the light-shielding effect. It is also called black-and-white light-shielding film, or black and white glue for short. The backlight used has higher requirements for shading, so most black and white double-sided tapes are used on the backlight. In addition to black and white glue, there is also black vinyl glue, which is black on both sides and is mainly used to fix the backlight frame of the display components of mobile phones and other products. Black and silver glue is black on one side and silver on one side. In addition to shading, the silver side has a reflective effect. Relatively black and white glue is the mainstream product in the market. The characteristics of black and white double-sided tape, its main characteristics in production and use are not only in terms of viscosity, but also in terms of repulsion, anti-aging, high temperature and high humidity, etc. Comparing the viscosity of the black surface and the white surface, the white surface needs to be larger because the white surface is connected to the rubber frame, while the black surface is connected to the glass. Compared with the adhesion of the glass to the glue, the rubber frame is worse, so the white surface needs to be more viscous. Dai Lai ensures the stability of the entire module. This is also a feature that customers are relatively concerned about when using it. The market demand for black and white double-sided tapes. Since small-size LCD modules are mainly used in mobile phones and similar terminal products, the annual production volume of mobile phones and similar products is basically the demand for black and white double-sided tapes in the entire backlight industry.
Product description Black and white double-sided tape is a double-sided tape made with a black and white two-color film as the base material using a special process. It is compounded with a special black and white base material. It has excellent overall performance, has light-shielding and reflective functions, and the white side is almost Does not absorb light, has good black surface shading effect, no pinpoint light transmission, suitable for fixed and backlighting.
