  • Patent number: 10126885
    Abstract: Disclosed is a capacitive touch panel having a circuitous conductor pattern structure. The capacitive touch panel contains a number of first axial conductor assemblies and a number of second axial conductor assemblies, wherein each second axial conductor assembly includes a number of second axial conductor cells which are composed of a number of bar shape figures with accordion shape or wave shape edges. Electrical fields and induced capacitors are generated between adjacent axial conductor assemblies with different directions when giving control signals. Then the touched position is detected. Circuitous conductor pattern increases the region of the first axial conductor assembly and the inducing range of electrical field, thus the amount of the axial conductor assemblies and conduction lines can be reduced.

  • Patent number: 10067619
    Abstract: In one embodiment, a method for determining the location of a touch on a touch sensor includes receiving input signals in response to a touch proximate to a location on the touch sensor. Each input signal may have a total capacitance that includes a first capacitance associated with the touch and a second capacitance that is parasitic capacitance. The parasitic capacitance of one or more of the input signals may be adjusted to result in the second capacitance of each of the input signals being substantially equal. An average capacitance of the adjusted input signals may be calculated. The location of the touch on the touch sensor may then be determined based on a comparison of the total capacitance of each of the input signals and the average capacitance of the input signals.
