  • Patent number: 11036338
    Abstract: A touch system includes a touch-sensitive surface with emitters and detectors arranged around its periphery. A touch event caused on an object interacts with optical beams that propagate from the emitters along the touch-sensitive surface to the detectors. Beam data indicating detected intensities of the optical beams is received. The touch system determines a set of measured interactions of the optical beams with the detected touch event from the beam data and compares the set of measured interactions with sets of model interactions of the optical beams for different candidate touch feature sets. Based on the comparison, the touch system selects one of the candidate touch features sets for the touch event. The touch system may also classify the touch event as having been caused by a particular object (or class of object) based on the selected touch feature set.

  • Patent number: 10871845
    Abstract: Disclosed are a touch display panel and a touch display device. In a touch display panel and a touch display device, a shielding pattern is arranged between a data link line and a touch link line in a non-active area of the touch display panel, and a signal corresponding to the touch driving signal is applied to the shielding pattern. Parasitic capacitance between the data link line and the touch link line is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line. Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.
