  • Publication number: 20160378239
    Abstract: A touch sensing device comprises a display panel including a plurality of data lines and a plurality of sensor interconnection lines, the plurality of data lines connected to a plurality of pixels of the display panel, and the plurality of sensor interconnection lines connected to a plurality of touch electrodes of the display panel, each pixel including a plurality of sub-pixels that each display a distinct color. A pattern of sub-pixels is arranged in the display panel such that a same number of sub-pixels for each distinct color is arranged adjacent to a first side and adjacent to a second side of one or more of the plurality of sensor interconnection lines, each of the sub-pixels for each distinct color being adjacent to either the first side or the second side of a corresponding one of the sensor interconnection lines.
