Product Description
Capacitive screen
By taking advantage of human body current sensing, the screen surface is coated with conductive materials. When a finger touches it, the changes in the electric field are detected by the sensor.
It only responds to conductive objects. It is ineffective to operate ordinary insulators (such as gloves, plastic pens) with fingers or capacitive pens (with conductive materials).
Supports multi-touch, can recognize multiple touch points, and achieve gestures such as zooming and rotating.
Electromagnetic screen
Relying on the electromagnetic pen signal, there is a grid antenna below the screen. The electromagnetic pen emits electromagnetic signals, and the screen precisely positions after receiving them.
Detection can be carried out without direct contact with the pen tip within about 1cm of the screen. Hovering operations may be possible (such as previewing the pen stroke effect).
High precision and professional-level pressure sensing (such as 2048 levels), suitable for drawing and note-taking, but usually does not support finger touch or multi-touch.
