interactive screen real.( 2) It is difficult to fit the explosion-proof film. Another problem with OGS is the fit of explosion-proof membranes. In addition to being prone to yellow light and uneven unevenness, explosion-proof film bonding also affects light transmittance, touch sensitivity, or power consumption performance. At present, many touch panels are accustomed to adopting optical tape (OCA) bonding technology with high production efficiency and easy uniform thickness during the bonding process. However, during this bonding process, small bubbles are easily generated, which leads to a decrease in yield. And these tiny bubbles may expand over time. Only by using expensive vacuum equipment can the opportunity be suppressed. In addition, there is no way to rework optical tapes, and most of the defective products can only be scrapped, which results in reduced production efficiency and increased pressure on the bonded products. The more thoughtful way is to use the liquid optical adhesive bonding technology. However, although this technology has obvious advantages, it is more difficult to adjust the thickness and maintain the parallelism. If there is too much optical glue during lamination, it is easy to cause overflow glue, and too little will cause uneven surface unevenness.
