隨著科技的進步與發展,市面上有多種電子裝置都採用觸控面板(touch panel)或觸控板(touch pad)作為操作介面,使用者通常以手指在觸控面板上操作,但是用手指在觸控面板上滑動時因手指接觸面積較廣而容易造成摩擦力太大,不適合大量或快速輸入,同時也可能發生誤觸的情形,因此便有觸控筆問世。With the advancement and development of science and technology, various electronic devices on the market use touch panels or touch pads as the operation interface. Users usually operate on the touch panel with their fingers, but with their fingers When sliding on the touch panel, due to the wide contact area of the finger, it is easy to cause too much friction, which is not suitable for a large amount of or fast input, and may also cause accidental touches, so the stylus has come out.
既有的觸控筆可分為主動式與被動式,其中主動式觸控筆是由筆內的訊號發射電路發送訊號,而使相應的觸控面板(或觸控板)收到訊號後判斷其被接觸位置的座標以及觸壓力。也就是說,主動式觸控筆是通過筆芯受驅動(書寫)時,將筆芯所受的壓力傳送至壓力感測器以產生觸壓力的感測訊號。Existing stylus can be divided into active and passive stylus. The active stylus sends a signal from the signal transmitting circuit inside the pen, so that the corresponding touch panel (or touch panel) can judge its status after receiving the signal.
