Embodiment Construction
[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0027] The embodiment of the present invention proposes a novel self-capacitance detection method. When the sensing unit is touched, the touch point can divide the sensing unit into two resistances, and the self-capacitance detection can be determined by considering these two resistances at the same time. The position of the touch point on the sensing unit. like image 3 As shown, it is a schematic diagram of the detection principle of the touch device according to the embodiment of the present invention. When a finger touches the sens...
