The commercial conference tablet market continues to grow, and capacitive touch screens will gradually replace traditional infrared touch screens, providing a broad application space for the company's touch capacitive screen technology. Since 2020, the demand for commercial conference tablets has continued to increase as a result of the epidemic and the normalization of telecommuting. At present, commercial tablets in the market are still dominated by infrared touch technology, accounting for 86% in the third quarter of 2020, while capacitive touch technology accounts for only 9.7. Capacitive touch screen supports multi-touch, with higher degree and faster response. At present, the technology is gradually mature, the price is declining, the yield is also increasing, and the market share is increasing.

At present, the car regulation touch MCU this sub-area, mainly by the two head manufacturers monopoly, and the continuous supply is in short supply, domestic players in the car regulation capacitive touch button field has been absent. Therefore, the mass production release of the micro-touch MCU series not only fills the gap in the local supply chain of this type of automotive gauge chip, but also provides a strong guarantee for the subsequent outbreak of automotive smart keys and smart surface applications. At the same time, with its innovative products and solutions, Micro is expected to achieve.

Answer: The company's touch display business is mainly the research and development, production and sales of touch screens and touch display integration related products. The products mainly include capacitive touch screens, touch display modules, cover glass, vehicle touch screens, etc. The company is in the middle of the touch display industry chain, product positioning market segments, the implementation of differentiated development strategy. The company's touch display products are mainly large and medium-sized, used in tablets, notebooks, automotive electronics, industrial control (such as treadmills, etc.), Internet of Things smart devices and other fields. Other major suppliers of domestic touch display products are, and so on.

In the field of mobile phones, resistive screens have been largely eliminated and are now replaced by better touch effects. The reason for this situation in the field of mobile phones, I think it is still related to the operating system of mobile phones.

The cancellation of the keyboard and the use of touch screen marks the official entry of the mobile phone into the intelligent era. The principle of the current popular capacitive screen is very simple. Using conductive and transparent ITO (indium tin oxide) film, driving is made into M transmitting channels, induction is made into N receiving channels, and horizontal and vertical interlacing is made to form mutual capacitance, that is, touch sensing points. The pattern can be made into strip, double strip, double-sided diamond, diamond hexagon and so on.

The implementation elements of intelligent surface and intelligent touch are perception and feedback, which means that perception is the need to perceive the user's actions. The implementation methods include capacitance, resistance, inductance, photoelectric, etc. Feedback means that the user's actions need to be confirmed or reminded by feedback. The implementation methods include vibration, sound, light, etc.

In the field of notebook computers, there are also such screens that can rotate 360 degrees while maintaining the conventional form of notebook computers. Multi-touch capacitive screens that can be handwritten and touched can be switched at will between office thin and light books and large-screen high-performance tablets at any time.
