1. Embedded Touch Technology
As users' demands for mobile phone screen visual effects gradually increase and touch and display companies continue to expand their product lines, the trend of fully laminated touch display integration is evident. Touch manufacturers such as TPK, Wintek, and Dahong are actively developing OGS, while panel leaders such as LG, Samsung, and Sharp are accelerating the application of on/in-cell technology. In-cell lamination technology has a higher process difficulty and cost, and is currently mainly used in high-end models. However, as traditional OGS and on-cell screen technologies and production efficiency reach bottlenecks, in-cell technology will increasingly be favored by mobile phone manufacturers, and the market is expected to expand further in the future.
2. OLED Display Technology
OLED is the most promising new display technology after CRT (cathode ray tube) and FPD (flat panel display). It has advantages such as ultra-thinness, high brightness, wide viewing angle, low power consumption, high definition, and flexibility, effectively meeting consumers' new demands for wide viewing angles, thinness, flexibility, and high color saturation. AMOLED is the most widely used. Currently, Samsung, Gionee, ZTE, and other brands have all released flagship models equipped with AMOLED screens. With the mass production of domestically produced AMOLED screens, the adoption and popularization of AMOLED screens will accelerate.
3. 3D Glass
3D glass features a curved design, conforming to ergonomic requirements. It also boasts excellent heat dissipation, good elasticity, and is not easily broken. In particular, using 3D glass as the back panel of a phone effectively solves the problem of traditional metal phone cases shielding radio signals, thus enabling wireless charging and high-bandwidth, high-speed next-generation mobile communication technologies. It has received widespread attention from mobile phone manufacturers in recent years. Currently, many high-end models such as the GALAXY S6 edge, GALAXY S7, and vivo Xplay5 are equipped with 3D glass covers. Brands such as Huawei and OPPO plan to apply 3D glass, and the future of 3D glass may see rapid development.
4. Sapphire Material Application
Sapphire material has high hardness and a high dielectric constant. Glass covers made from sapphire have excellent thermal conductivity, scratch resistance, fingerprint sensitivity, and a beautiful appearance. Currently, companies such as Lens Technology and Zhaoyuan have achieved mass production of sapphire mobile phone cover glass, which is widely used in consumer electronics fields such as smartphones and wearable devices. Flagship models such as Huawei P7, vivo X5L, and Gionee Tianjian W808 have all adopted sapphire screens. In the future, as sapphire manufacturing technology matures and production costs continue to decrease, sapphire screens will see accelerated adoption and widespread use.
