Description of the Invention: [Technical Field] The present invention relates to touch panel sensing technology, and more particularly to a touch sensing technology for implementing multiple sensing line panels with a small number of sensors, which is applicable to various Size touch panel. [Previous Technology] The touch sensing technology determines the sensing line where the finger is located by logical calculation by changing the physical parameters between the sensing element and the finger above it (including other various types of pointed objects). The position and its action can be divided into three major categories: resistive, capacitive, and optical. Resistive touch sensing Because of its simple circuit and low cost, it is the mainstream of the current small-size touch product market; however, its color rendering and touch sensitivity still fail to meet consumer requirements. Capacitive touch sensing is becoming the most potential R&D focus for small-sized touch products due to its high sensitivity and high controllability, even without touching the surface of the sensing components. For large-size touch sensing technology, optical touch sensing is currently the main development, but its resolution and related technologies are still not mature, and generally the larger the touch panel, the more the number of sensing lines required. Then the number of infrared transmitting and receiving pairs increases and the circuit structure tends to be complicated. In addition, for a touch panel with two-dimensional coordinates, it is necessary to provide different sensing lines of the X-axis and the Y-axis, which is sufficient for judging the two-dimensional coordinate position of the finger, and the number of sensing lines required is increased, and the circuit cost is correspondingly increase. In order to solve the above-mentioned deficiencies of the prior art, one of the objects of the present invention is to provide a touch sensing technology that can realize touch sensing of a plurality of sensing line panels with a small number of sensors. Suitable for touch panels of various sizes. Another object of the present invention is to use a touch sensing trace group coding method, so that the sensing technology originally only applicable to small-sized touch products can be applied to the development of a large-sized touch panel. In order to achieve the above object, an aspect of the invention discloses one
