Electromagnetic screens are made of conductive materials and are used to suppress the penetration of changing electromagnetic fields into a specified area. Electromagnetic touch has been available since 1964. It was used in smart tablets from the 1970s to the 1980s. Many high-end computer-aided drawing (CAD) systems such as AutoCAD are widely used, and the Apple computers of that year were also used as AppleII equipment.
Electromagnetic screen technical level analysis
Compared with the current mainstream capacitive and resistive screens, the electromagnetic screen technology is called the crown of 2012 touch technology by virtue of a series of advantages such as realizing "original handwriting" input, higher accuracy and faster response time Gems. And because of this, the current electromagnetic screen technology has been applied in more and more industries, and the development momentum continues to rise. According to industry analysis, electromagnetic screen technology contains huge potential for development, and 2013 will be an important year for the development of electromagnetic screen technology.
From a technical level, through the core component of the electromagnetic screen technology, the built-in pressure-sensing device of the electromagnetic pen is combined with the change of the magnetic field. In addition to the finer X and Y axes, the electromagnetic screen technology can also realize its unique Z axis. It is also the key that the electromagnetic screen can realize the "original handwriting". At the same time, the touch is more accurate, the synchronization and response time are also enhanced, whether in the input method or touch experience, the electromagnetic screen technology is better than the capacitive and resistive touch screen technology . It is also because of this that electromagnetic screen technology has been applied in more and more industries, especially in the field of education.
The representative manufacturer of the main electromagnetic technology in the market, the largest Wacom is dominated by its own brand. The revenue in the first three quarters of 2009 was NT $ 8.1 billion. The product pricing is higher and the resolution can be 5,000 lpi; That is committed to the high-accuracy CAD / CAM market with drawing functions, and now also offers 100-inch large-size products. In fact, the electromagnetic technology can be spliced, which can be said to have no size restrictions at all. N-Trig is a component supplier with relatively high cost. Taihan was established in 2004, the unit cost of the product is low; the cost of the electromagnetic type above 10 inches is low, and the resistance type has a price advantage if it is below 10 inches.
Application market
The main application markets for electromagnetic touch include pen-type tablets that use the most USB interfaces, tablet monitors commonly used in the education market, growing whiteboards in the Asian market, signature boards for e-commerce, POS, and electronic devices with increased handwriting capabilities Book readers, Samsung products are built-in electromagnetic sensing module, can provide notes, notepad function, TabletPC, and Tablet & Book. E-book readers are considered to be a fairly fast-growing market in recent years, and the trend towards soft displays is obvious. The electromagnetic touch module is flexible and can be used with a flexible display; although the use of a pen is considered to be a disadvantage, the pen size is small and can be integrated into the system.
It is estimated that the potential market for electromagnetic touch technology is estimated to be the most watched for growth in e-books and TabletPCs, with growth rates approaching multiples from 2010 to 2012, and total shipments are expected to grow from 9.9 million in 2010 to 14.7 million in 2011 , Reached 24.8 million in 2012. Taihan currently has 117 patents and possesses core technical advantages.
