Problems solved by technology

Although the liquid crystal module has many advantages, but at the same time, the module has strong sensitivity. When the liquid crystal module is squeezed by external force, it is easy to produce light leakage phenomenon (also called stress mura phenomenon), which affects the vision of the client. Effect

Abstract

The invention discloses a PU black foam double-sided tape material. The material is formed by sticking an easy-to-pull adhesive material layer, a foam layer, an ultrathin black PET base material layer, a shading adhesive material layer and a double silicon PET release film base material layer in sequence from top to bottom; the thickness of the PU black foam double-sided tap material is 0.46-0.86mm. By combining multiple test detection, the material has the following advantages that the material is light, excellent adhesion is achieved, the adhesion to a thin edge is excellent, the stress relieving effect, reflex action resistant property, surface resistance and anti-rejection property are good, the material can be removed safely on a glass panel and the surfaces of a PC, stainless steeland plastics, the die-cut machining property is excellent, and the material is applicable to large-size intelligent TV module assembly and the like.

Description

technical field [0001] The invention relates to the field of adhesive product materials, in particular to a PU black foam double-sided adhesive tape material. Background technique [0002] In recent years, as people's requirements for the quality, size and on-the-spot effect of intelligent display images have increased, more and more large-size LCDs have become the first choice of consumers; to make the LCD screen display images correctly, LCD backlight modules The design is the key, its comprehensive performance and cost, the designer must choose the lamp beads reasonably, design the matching lens and add the appropriate optical device; the backlight module converts the point light source into a uniform surface light source, while ensuring the necessary light Energy utilization and uniformity. [0003] As the market and customers demand more and more wide viewing angles for liquid crystal displays, the resolution of liquid crystal modules has been greatly improved, and liq...
