With the continuous improvement of imaging quality, acceleration of imaging speed, and continuous reduction of radiation dose of digital X-ray detectors, they have been recognized by clinical institutions and imaging experts around the world. X-ray machines with detectors as core components are widely used in various fields of medicine and industry. Data shows that the global market size of digital X-ray detectors in 2018 was approximately 1.73 billion US dollars, with medical products accounting for about 74% of the market share, and industrial security products contributing to the remaining market. It is expected that by 2024, the global market size of digital X-ray detectors will reach 2.48 billion US dollars.
The application range of digital X-ray detectors is very wide, involving different fields such as medical, industrial non-destructive testing, and security inspections; According to the working mode, it can be divided into static and dynamic products. The demand for digital X-ray detectors varies greatly in different scenarios, requiring multiple technologies to meet it. From the perspective of technological development trends, digital X-ray detectors are moving towards greater sensitivity and lower noise, while technologies such as CMOS, IGZO, and flexible substrates are also research and development directions in the industry; From the perspective of customer demand, digital X-ray detectors are developing towards low radiation dose, real-time and fast imaging, cone beam CT imaging and 3D rendering, lightweight and portable, and intelligence.
Digital X-ray detectors are typical high-tech products and belong to the high-end manufacturing industry. As the core component of the whole machine, the quality and performance of digital X-ray detectors play a decisive role. The R&D cycle of X-ray detector products is usually long, and enterprises need to gradually form core technologies and processes through years of R&D accumulation. It is difficult for new entrants to master key technologies in a short period of time and produce products that meet market demand. The main technical barriers to entering the industry include difficulty in designing TFT SENSORs, difficulty in mass producing TFT SENSORs, difficulty in mass producing scintillators, and high requirements for interdisciplinary applications and image chain integration.
