    Abstract: A touch display device and a touch driving circuit are configured to drive at least one of the plurality of first touch electrode lines disposed in a first area with a first touch driving signal having a first touch driving frequency, and drive at least one of the plurality of second touch electrode lines disposed in a second area with a second touch driving signal having a second touch driving frequency that is different from the first touch driving frequency. Each of the first touch driving frequency and the second touch driving frequency is different from a display driving frequency related to display driving. to the touch display device reduces the influence of noise, increases the signal-to-noise ratio, and reduces the influence of driving the display, thereby improving the touch sensitivity.

    Abstract: The disclosure is related to a touch display device including a display panel. By dividing an active area of the display panel into a plurality of sub-areas, and driving a touch electrode disposed on each of the plurality of sub-areas separately, a load of the touch electrodes is reduced depending on a size of the display panel and a performance of a touch sensing can be improved.

    Abstract: A touch display device is disclosed. Since a touch electrode line included in the display device is divided into two or more touch electrode line parts connected to different touch routing lines, an entire load of the touch electrode line and the touch routing line can be reduced. As a portion of the touch routing line is disposed on an active area and touch routing lines connected to different touch electrode line parts are connected to each other between the active area and a touch driving circuit, an entire load can be reduced without an increase of a non-active area and an increase of a channel due to the touch routing lines, and a performance of a touch sensing can be improved.

    Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electrodes have different sizes or shapes or a located in different positions, a difference in capacitance is not formed among the touch electrodes. High touch sensitivity can be obtained. The touch display device comprises a plurality of touch electrodes, wherein a first touch electrode of the plurality of touch electrodes occupies a first area and comprises first mesh-shaped electrode metal. The touch display device comprises first dummy metal in a same layer as the first mesh-shaped electrode metal and in the first area occupied by the first touch electrode, the first dummy metal being electrically disconnected from the first mesh-shaped electrode metal.
