Description
Technical Field
The present disclosure relates to touch electronic systems, and more particularly, to a floor mat device of a touch electronic system.
Background
Electronic systems including touch functions are widely known, and touch panels and touch screens are main input devices for providing touch functions, and touch pens can be used for inputting the touch panels and the touch screens. The touch panel or screen using the capacitive sensing principle is quite easy to receive electromagnetic interference of the external environment or the devices in the electronic system.
Please refer to fig. 1, which illustrates a prior art electronic system 100. The electronic system 100 includes an electronic device 110 that can be erected on a floor or a floor 190, which can include a touch panel or a touch screen. The electronic device 110 may be used as an electronic whiteboard. At least one user 120 standing on the floor 190 may make inputs on the touch panel or screen using a hand or stylus 130.
In the example of fig. 1, the ground potential 111 of the electronic device 110 is different from the ground potential 121 of the user holding the stylus 130 because the points at which the two contact the ground 190 are different. Since the ground potential of the stylus 130 or the hand is different from that of the electronic device 110, the potential difference is an electromagnetic interference when the stylus 130 or the hand approaches or contacts the electronic device 110. In addition, the points at which the two contact the ground 190 are different and may be close to different sources of interference. For example, the user may be closer to an operating blower or cleaner, and the electromagnetic interference may be more powerful to the stylus 130 or hand.
Therefore, how to draw the ground potential of the stylus 130/hand and the touch panel/screen to the ground for reducing the touch sensing error is a need to be solved.
