  • Patent number: 11036341
    Abstract: A plurality of metallic components (e.g., conductive rods) can be included within an insulator layer of a touch sensor panel. The metallic components included within the insulator layer can be electrically floating. The metallic components can increase a signal coupling strength across the thickness of the insulator layer. In some examples, the metallic components can have a uniform spacing and uniform physical dimensions. In some examples, the metallic components can provide increased signal coupling in areas directly above touch sensitive regions of underlying touch sensor electrodes. In some examples, the metallic components can pass through the insulator in a straight line that is normal to opposing surfaces of the insulator layer. In some examples, the metallic components can be flared or otherwise pass through the insulator along a path that is not straight and/or not orthogonal to opposing surfaces of the insulator layer.

    Abstract: A touch display device accurately distinguishes a touch input performed using a finger and a touch input performed using a pen, such as a stylus, significantly reduce a touch sensing time, simultaneously perform a display operation and a touch sensing operation, and operate in a power saving manner. Touch sensing does not restrict an image display time of a display panel. Touch inputs are sensed without degradation in touch performance, which would otherwise be caused by parasitic capacitance occurring in electrodes within the display panel, such as data lines or gate lines.

  • Patent number: 11036325
    Abstract: Provided is a touch display device. Because a shielding electrode, which is disposed in a non-active area and electrically coupled between a common electrode and a common voltage supply line, is located between a touch routing line and a signal line, the effects of noise caused by the signal line on the touch routing line may be reduced. Further, an encapsulation portion located on the shielding electrode has a planarized structure. The resulting maintenance of a certain distance between the shielding electrode and the touch routing line may reduce noise caused by the signal line from indirectly affecting the touch routing line through the shielding electrode.

  • Patent number: 11036335
    Abstract: A method for calibrating a capacitive touch module includes: acquiring, for any of touch regions, touch parameters of the touch nodes in the touch region; determining whether the touch region is an abnormal touch region based on the touch parameters; and correcting the touch parameters of the touch nodes in the abnormal touch region based on the touch parameters, if the touch region is the abnormal touch region, so as to enable the touch parameters of the touch nodes in the abnormal touch region to be within a preset normal range. After the abnormal touch region of the touch module is determined, the touch parameters of the touch nodes in the abnormal touch region are corrected based on the acquired touch parameters so as to be within the preset normal range, thereby reducing the probability of abnormality of the touch module.
