On September 19, SCXH Optoelectronics Technology Group, an invisible champion in China's electronic glass industry, released a new ultra-thin, drop-resistant glass.
The thinnest glass is only 0.06 mm and will be used for mobile phone screens and back covers. The drop-resistant glass released this time is optimized for soda-alumina-silicate glass, which increases impact resistance and drop resistance, and can achieve 360 degrees Bending filled the domestic gap and was included in the touch screen material resource pool by manufacturers such as Huawei, Lenovo and Xiaomi.
According to the relevant professionals of SCXH research and development, compared with the first released strengthened soda-alumina-silicate glass, the surface compressive stress of the drop-resistant glass is more than doubled, the depth of the stress layer is 2 times higher, and the bending strength is increased by 1.5 times. The height of the drop is increased by more than 5 times, and the drop of 2 meters is "unbreakable" under certain conditions.
SCXH is mainly engaged in the research and development, design and manufacture of flat display screens, curved display screens, special purpose glass and other products. At present, SCXH has a high-strength ultra-thin touch screen glass production line with a production capacity of 10 million square meters per year. In terms of production capacity, the company ranks third in the world; the company's market share is approximately 21.7%, ranking second in the world. At present, it has been supplied to well-known smart terminal companies at home and abroad in batches.
According to Yuan Tong, vice chairman and secretary-general of the China Electronic Materials Industry Association, because 5G mobile phones use millimeter wave technology, they are greatly affected by obstacles. Metal and plastic back covers are very easy to interfere with signals. They will inevitably be eliminated in the 5G era and replaced by It will be a "double glass structure", that is, the front and back covers of the phone are made of glass. Therefore, the requirements for the strength of cover glass will be higher in the future, and the demand for drop-resistant glass will increase sharply.
It is worth mentioning that the choice of 5G mobile phone cover materials is mainly glass, ceramics, and composite materials, involving many listed companies. With the advantages of cost, look and feel, and signal transmission, glass materials are recognized as the mainstream choice.
SCXH person in charge Liu Zaijin said that the development of dual-folding mobile phones is slow. The screen material currently used is polymer PI material, and the curved ultra-thin glass material has the advantages of no fatigue and wear resistance, which will be a major trend in future development. The industry predicts that the number of foldable mobile phones will reach 75 million in 2023.
China's first master of high-aluminum cover glass technology
In 2010, SCXH was established to develop domestic plasma glass. The company focuses on the field of aluminum silicate glass. Through independent innovation, technological research, production line transformation, and quality improvement, it has explored and mastered the PDP glass and high-aluminum cover glass process technology with independent intellectual property rights.
The SCXH team broke the international technology monopoly through core technologies and became the first company in China with independent intellectual property rights and mass production capabilities for high-aluminum cover glass.
It is worth mentioning that cover glass is an important key component of the touch screen industry. Previously, domestic manufacturers of mobile phones, tablets, and touch notebooks that demand cover glass were all dependent on imports.
SCXH's technology has promoted the localization of high-end touch protection glass, and ended the passive situation of the display industry in the high-end touch protection glass, and reduced the cost of the industry by about 30%.
In addition to 5G mobile phones, the rapidly growing automotive display market has also created market space for cover glass. According to Qunzhi Consulting's survey data, the total shipment of vehicle display panels in 2018 was about 160 million (excluding after-installation), an increase of about 6% year-on-year. In 2019, 170 million pieces of vehicle display panels are expected to be shipped, a year-on-year increase of about 5%.
In April this year, the world`s top panel manufacturers signed a "strategic cooperation agreement" with SCXH, covering high-aluminum cover glass substrates, AG glass, automotive glass cover, mobile terminal glass cover, smart home glass cover and A strategic cooperation was reached in the research and development and application of new materials for optoelectronic displays and flexible display materials.
SCXH has made multiple strikes in the field of cover glass, and is planning to produce drop-resistant glass and lithium aluminum silicate glass, ultra-thin glass, curved glass, automotive and anti-glare glass. It will also increase investment in the anti-glare glass and flexible glass industry. which strive to achieve mass production of products in 2020.
