Technical introduction of "H&T stylus pen"
Operating principle of electronic pen
H&T ‘s stylus pen applies the principle of electromagnetic induction to detect the presence and pressure of the pen.
When the electronic pen is brought closer to the touch pen sensor, the value of the electromagnetic coupling between the coil of the orthogonal cell part in the sensor and the resonance coil of the electronic pen changes.
The change in the value of this electromagnetic coupling is captured as a signal, and the coordinate position is calculated from the output value of each cell in which the change in coupling is detected.
At that time, by detecting the phase, pen down and pen pressure are detected.
Unique electronic pen technology developed by H&T Technology
[Part 1] "Pressure detection technology" that realizes excellent drawing performance and natural writing comfortable.
◆Original pen pressure detection technology (patented)
H&T Technology has developed a unique pen pressure sensing technology (patented) by making full use of the semiconductor and electromagnetic induction technology cultivated to realize a simple and high-performance low-cost electronic pen.
H&T’s stylus pen can express the strength, color depth, touch feeling, etc. when drawing, the drawing performance is excellent, so you can experience the fun of pen writing & drawing.
In addition, it is battery-free and can be stored in a smartphone or tablet, making it convenient to carry!

[Part 2] H&T's unique "hybrid touch pen sensor technology"
◆Hybrid sensor technology that enables low-cost products
H&T Technology has developed its own hybrid touch pen sensor, succeeded in reducing the number of parts and mounting costs to achieve the low cost!
Conventional electronic pens with electromagnetic induction have two types of sensors a finger touch sensor & a pen sensor, in which, it is difficulty of adjusting these sensors has been an obstacle to their adoption.
H&T Technology has achieved a finger touch sensor and a pen sensor with a single hybrid sensor. It becomes more fixable in panel selection, simplifies assembly, and enables low-cost products.
