數位板是靠磁場工作的,板面上有一層電磁場,電磁筆通過不同的方式也會產生電磁場,工作時,通過計算兩種磁場之間 互相作用的結果來定位並判斷電磁筆的運行軌跡,通過計算電磁場的大小,回饋壓感的大小,從而使繪畫書寫時還原使用者筆 跡。
數位板用電磁遮罩片以鐵基非晶帶材為主要原材料製成,具有高磁導率、低損耗的特性,工作時增強磁通量,提高繪畫靈敏 度。可製成最薄至 0.1mm的磁性薄片,材料為柔性,不會變形或碎裂。
Digital board works by magnetic field, the surface has a layer of electromagnetic field, electromagnetic pen
through different ways to produce electromagnetic fields, computer calculates the results of interaction between the two kinds of magnetic field to locate and determine the trajectory of the electromagnetic pen when it works, through the calculation of electromagnetic field size to feedback the Pressure data, So as to restore the handwriting whenuser writing and drawing.
Electromagnetic Shielding Materials for Digital Plate i s madeof iron-based amorphous ribbons,the amorphous electromagnetic sheet with high permeability andlow loss, i t can enhance the magnetic flux andimprove the sensitivity of the painting whendigital boardat work. Min.100μ m magnetic sheet can be made, the material i s flexible, will not be deformed or fractured.
