    Abstract: A touch screen panel includes a substrate and a black matrix located on the substrate in a mesh pattern. On the black matrix are formed a first touch sense electrode and a second sense electrode. The first touch sense electrode extends in a first direction and the second touch sense electrode has a plurality of blocks extending in a second direction. An insulation layer with openings exposes portions of the blocks of the second touch sense electrode. A connection electrode connects the adjacent blocks of the second touch sense electrode via the openings in the insulation layer. The first touch sense electrode and the second touch sense electrode are covered by the pattern of the black matrix.

    Abstract: A display device integrated with a touch screen panel, and a method of driving the same, can prevent parasitic capacitance that would otherwise increase the load during a touch operation, lower the accuracy of touch sensing, or make touch sensing impossible. The display device includes data lines, gate lines, and a plurality of electrodes spaced apart from each other. A common voltage is applied to the electrodes in a display driving mode and a touch drive signal is applied to one or more of the electrodes in a touch driving mode. A data voltage is applied to the data lines in the display driving mode. A scan signal is supplied sequentially to the gate lines in the display driving mode and the touch drive signal or a signal corresponding to the touch drive signal is applied to one or more of the gate lines in the touch driving mode.

    Abstract: A display device and a display panel may comprise a substrate comprising a display area including a plurality of subpixels and a non-display area including a pad area spaced apart from the display area in a first direction, a first sensor electrode in the display area and extending in a second direction crossing the first direction, a second sensor electrode in the display area and extending in the second direction, a first pad in the pad area, a second pad in the pad area, a first trace line electrically connecting the first sensor electrode and the first pad and a second trace line electrically connecting the second sensor electrode and the second pad. The second sensor electrode may be positioned closer to the pad area than the first sensor electrode. The first trace line overlaps the second sensor electrode, and the second trace line may include a first meandering portion.

    Abstract: A touch display device is disclosed. By making at least one of a thickness or an angle of inclination of an insulating layer disposed on an area where a touch routing line is disposed on a non-active area of a display panel and an area that lacks the touch routing line to be different from each other, a short circuit between touch routing lines due to a defect in a process arranging the touch routing lines can be reduced.
