Electromagnetic screen technology: electromagnetic screen is an electromagnetic pen that emits electromagnetic waves intermittently. When the electromagnetic pen is close to the electromagnetic plate, the internal coil will sense the electromagnetic wave emitted by the electromagnetic pen. Electromagnetic induction technology is composed of an electromagnetic pen that can emit electromagnetic waves and an electromagnetic plate that receives coil grids in horizontal and vertical directions according to certain rules. The main application markets of electromagnetic touch include handwriting boards with the most USB interfaces and flat panel displays commonly used in the education market.

Electromagnetic screen and stylus: The main application markets of electromagnetic touch are handwriting board with USB interface, flat panel display commonly used in education market, electronic whiteboard growing in Asian market, e-commerce, signature board used by POS, and e-book reader with handwriting function.

Uniview (USA) was established in California on 20 1987. Youpai and Hanwang Technology set up a joint venture factory in Shenzhen. Its production and sales mainly include handwritten electromagnetic pen LCD and its components, providing diversified and cost-effective handwritten electromagnetic pen LCD related products for industry users. These products will be used in finance, commerce, government office, public exhibition and industrial control.
