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.

Strong versatility, can be used as a human-computer interaction platform-level car gauge chip selection, suitable for almost all human-computer interaction scenes in the car, whether it is single pressure, single capacitive touch or the fusion of the two scenes.

It is said that the dual-mode scheme of pressure touch and capacitive touch fusion is adopted, its high-sensitivity pressure detection is used to identify the pressing action, and the capacitive touch is used to locate the pressing position. The two are complementary, and the overall scheme has the comprehensive advantages of high reliability, low cost and simple application. At present, the major European and American suppliers of car regulation chips have the problems of price increase and shortage. The launch of this series of chips will provide a differentiated choice for car companies.

main products: touch panel, mobile phone touch screen, touch screen tablet pc, car gps touch screen, intelligent learning machine touch screen. main products: resistive/capacitive touch screen. main products: capacitive touch screen, resistive touch screen, optical touch screen and touch screen control card.

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.

When we select the touch screen, we should not only pay attention to the cost, size, resolution and other factors, but also decide according to the application environment, application population and product market of the product. Founded in 2009, it is a high-tech enterprise dedicated to touch product research and development, manufacturing, sales and service. Its factory is an earlier domestic research and development manufacturer and has won many brand awards.

Capacitive touch screens are more common in products that everyone comes into contact with. For example, smart phones and tablet computers generally use capacitive touch technology. On conference tablets, capacitive touch can be directly operated by fingers, with more sensitive response and no need to worry about accidental touch. Fine writing and pressure feeling can be realized with active capacitive pens. Due to high cost, only some high-end conference tablets use capacitive touch technology. However, in large screens, capacitive touch screens are relatively few, the sensitivity of capacitive screens will decrease with the passage of time, and the maintenance cost is very high. It is often necessary to replace the whole screen when touch interaction is not possible or when the screen is abnormal. For infrared nano blackboards, the maintenance convenience is more convenient and the cost is lower.
