With the advent of the era of Internet of Everything, cutting-edge technological concepts such as 5G, artificial intelligence, virtual reality and big data have driven consumer electronics products to usher in a new round of upgrades and popularization: 5G technology has led to a significant increase in the shipment volume of the global smartphone market, especially in the Chinese market, achieving rapid growth after the replacement of existing stocks. Wireless charging has regained attention due to Apple's joining the Wireless Power Consortium (WPC). It is estimated that the market size will exceed 10 billion US dollars in 2024. The size of TV panels has been increasing year by year, with an average annual growth of about 1 inch, driving the demand growth rate of LCD screens to remain between 5% and 8% in the next three years. OLED flexible screens have attracted much attention due to their adaptability to the needs of wearable devices. Although the panel industry has been fully localized in China, the demand for local production of optical materials remains strong. Pressure-sensitive adhesive materials play a crucial role in the manufacturing of electronic devices: ① In the field of wireless charging, pressure-sensitive tapes are used to bond, fix and protect the receiving and transmitting modules to ensure their effectiveness. ② In the display field, optical pressure-sensitive adhesives maintain the transparency of the internal optical materials of the screen in high-temperature and high-humidity environments, ensuring clear imaging. ③ Pressure-sensitive adhesives are also used to protect precision electronic components (such as screens, etc.) from being damaged during the manufacturing and transportation processes. Silicone pressure-sensitive adhesives are widely used in protective films in the electronics industry, providing comprehensive protection for the manufacturing, transportation and use of precision components.
