It has been widely used in various electronic products. Generally speaking, the touch sensing device can be divided into three types: capacitive touch panel, resistive touch panel and electromagnetic touch panel. The boards have their own features, advantages and disadvantages, so the current development application layer is also different. For example, resistive touch panels are often deployed in personal digital assistants (PDAs)' electronic dictionary, mobile phones, MP3 digital players or It is used on the screens of small electronic products such as satellite navigation screens (Gps), while capacitive touch panels are mostly used as notebooks for notebooks, virtual touch buttons, etc. - In-step, the known capacitive touchpad structure includes -# sensing layer (χ trace) and -y axis yee (y traee) 'χ, y minus touch insulation to set the touchpad Inside the body' and ground the x, y-axis sensing layers and connect them to a control circuit.

The principle of the signal processing of the signal principle is that the interrupt signal processing mode is not interrupted or changed. For example, in a non-continuous or new touch sensing operation, a pre-selection will be automatically selected. The priority signal processing mode is set to operate. For example, the preset is based on the capacitive sensing signal. When a mode of operation is selected, the signal processing operation is as described in the above paragraphs. In some special requirements, the signal discriminating circuit of the signal processing unit 3 can also be replaced by a manually operated signal switching switch, so that the user can operate the signal switching switch to determine the desired signal processing mode. When the signal switching switch selects the electric valley sensing signal processing mode, the signal processing unit 3 only accepts and handles the sensing signal of the capacitive touch panel unit 1 and blocks the resistance type from being accepted. The sensing signal of the touch panel 'unit 2; similarly, when the signal switching switch selects the resistive sensing signal processing mode, the signal processing unit 3 only accepts and processes the sensing signal of the resistive touch panel unit 2 And block the inductive signal from the capacitive touch panel unit.
