The first silicon-based OLED evaporation machine was successfully introduced into the mass productio

Recently, the first silicon-based OLED evaporation machine developed by Hefei xinyihua Intelligent Machine Co., Ltd. (hereinafter referred to as "Hefei xinyihua"), an intelligent equipment manufacturer in the pan semiconductor industry, was successfully introduced into the mass production line of Taizhou Guanyu Technology Co., Ltd. (hereinafter referred to as "Guanyu technology") and lit in full color, This marks a new milestone in the realization of the autonomy of the core process equipment of China's Pan semiconductor industry.

It is reported that Guanyu micro display adopts colorless film and self luminous native RGB AMOLED technology, which can realize high pixel density, high brightness, high contrast, high color saturation and low power consumption. As a domestic manufacturer of OLED equipment, Hefei xinyihua has successfully completed the development of silicon-based OLED evaporation machine, the core process equipment. This is the first silicon-based OLED evaporation machine independently developed and launched in China. Based on long-term technical accumulation, Hefei xinyihua has overcome the technical problem of "neck sticking", and successfully developed G1 (evaporation substrate size 200 * 200mm) and G2 5 (size of evaporated substrate 370 * 470mm) OLED evaporation machine and G6 H (size of evaporated substrate 925 * 1500mm) evaporation machine are another major breakthrough after the key devices, and it is also another milestone on the road of self-determination of core process equipment in China's Pan semiconductor field.

The vapor deposition machine is the core equipment in the preparation of OLED display devices. The vapor deposition machine evaporates organic light-emitting materials onto the substrate accurately, evenly and controllably, which is not only the most key factor to promote the industrialization of relevant technologies, but also the core element to ensure the smooth mass production of high-precision display products. Hefei xinyihua has overcome the technical problems of film thickness uniformity, stability and micron high-precision positioning of silicon-based OLED evaporation machine by learning from the R & D and design experience of OLED evaporation machine and relying on the secondary innovation of evaporation source design and alignment technology of OLED evaporation machine. At the same time, for some special evaporation materials, through the evaporation trend simulation, develop specific evaporation sources and formulate evaporation processes to achieve long-term stable evaporation.

Hefei xinyihua now has a 30000 square meter clean workshop for the development of evaporation machines, more than 20 sets of various advanced R & D equipment and instruments, has established an international high-end talent team, and has formed a perfect technology R & D system of evaporation machines. Cao Jingbo, general manager of Hefei xinyihua OLED business department, said: "Hefei xinyihua has formed a perfect technology R & D system related to evaporation machine, and the relevant technical level in evaporation source, vacuum cavity, high-precision alignment, packaging and process control has reached the international advanced level." It is understood that the OLED evaporation machine developed by Hefei xinyihua has achieved a number of sales performance. It is a manufacturer of evaporation machine at the forefront of domestic R & D, production and sales. It takes innovation as the driving force, closely follows the market situation, and speeds up the research and development of new equipment such as silicon-based evaporation machine. Just as Lu Longming, general manager of Guanyu technology, said: "continuous innovation and open cooperation are the basis for the company to move towards sustainability." Zhang Haitao, CEO of Hefei xinyihua, said: "The company has completed the delivery of the first self-developed mass production silicon-based evaporation machine in China. On the one hand, it benefits from our long-term technical accumulation in the development of evaporation machine and its key devices, on the other hand, it benefits from the recognition and support of customers. It is the result of joint innovation between us and customers. We are very optimistic about the future development of silicon-based OLED display technology driven by yuancosmos and are willing to continue to provide Make our contribution to the rapid development of the industry. "

Silicon based OLED display devices are based on monocrystalline silicon chips. Using IC technology, the pixel density can reach more than 2000ppi, and the fineness is much higher than that of traditional display devices, which can perfectly fit with AR / VR and other devices. With the continuous expansion of market application, the attention to silicon-based OLED micro display products is increasing day by day. China Electronic Information Industry Development Research Institute predicts that the market scale of silicon-based OLED is expected to reach US $90 billion in 2023. Recently, the popularity of metauniverse has remained high. As a key equipment for building metauniverse, AR / VR has been highly sought after, and large Internet technology enterprises at home and abroad have made layout in succession. According to the data of IDC, the market scale of China's VR industry exceeded 40 billion yuan in the first quarter of 2021, with a year-on-year increase of 52.4%. Meanwhile, industry data show that the market scale of China's VR industry is expected to reach 105.16 billion yuan in 2023. In the face of favorable market prospects, relevant domestic enterprises have increased investment in silicon-based OLED related industries in recent years, which will bring a large demand market space for silicon-based evaporation machine in the future.
