Abstract

The invention provides a touch control device including a plurality of first sensing electrodes, a plurality of second sensing electrodes and a plurality of third sensing electrodes. The first sensingelectrodes extend along a first direction. The second sensing electrodes are in electric isolation with the first sensing electrodes and extend along a second direction. The third sensing electrodesare in electric isolation with the second sensing electrodes and extend along the first direction. At least one part of the first sensing electrodes, at least one part of the second sensing electrodesand at least one part of the third sensing electrodes are formed on different film layers separately.

Description

technical field [0001] The invention relates to an electronic device, in particular to a touch device. Background technique [0002] Whether it's a phone, tablet or laptop, touch devices have their place. The use of touch devices has also gradually advanced from finger touch to the use of active stylus. There are many technologies of active stylus, which can be mainly divided into electromagnetic type and capacitive type. The electromagnetic stylus requires an independent electromagnetic induction board, and the stylus is unique in that it can actively send signals through electromagnetic induction, and its performance has been excellent for a long time. The capacitive stylus achieves electric field output by preloading a voltage on the pen tip, and calculates the touch position of the pen tip above the touch panel through the electric field receiver at the sensing end. The biggest advantage of the capacitive stylus is that it does not need a separate sensor board, and th...
