interactive screen stand.( 1) Key bottleneck-glass strength. OGS can be divided into a small piece process that is cut first and then strengthened and a large piece process that is strengthened first and then cut. No matter which one, they face the dilemma of production efficiency and glass strength. In touch panels, glass is the main material, and strength is very important. Industry standards require strength above 450 MPa, so it must be strengthened on six sides. It is reported that the strength of the iPhone 5 reaches 800 MPa. However, after chemical strengthening, cutting or grinding, the strengthening of the hexahedron is destroyed. Unless the secondary strengthening process is added, the strength of the glass itself will be destroyed, and the strength of the glass frame will be weakened. However, during the secondary strengthening process, the temperature of the strengthening furnace, the concentration of the chemical solution, the immersion time, the filtering system, and leaving the field may affect the touch sensitivity of the final product. In addition, the chemical solution cyanuric acid used in the second strengthening is an unstable substance and contains strong and highly toxic substances. Accidental use will cause harm to the human body. Many countries have banned cyanuric acid. Therefore, the glass process of strengthening and cutting first has always been considered by all in terms of glass strength. In contrast to the large piece process, which is first strengthened and then cut, the small piece process is strengthened after cutting, edging, and chamfering, so there is no problem of insufficient strength, but the small piece process is not as efficient in production efficiency as the large piece process. At present, the whole strengthened glass is more effective in the yellow light process. The problem faced by the panel industry is that if the cut strengthened glass is used as OGS, it will inevitably encounter problems in the yellow light process. The production efficiency and equipment will be affected.
