A touch display device is disclosed. By arranging a part of a touch routing line for a driving of a touch electrode on an active area and electrically connecting the touch routing line to an auxiliary routing pattern that overlaps the touch routing line, an area where the touch routing line is disposed and a load of the touch routing line can be reduced.

Touch display device

Embodiments of the present disclosure are related to a display device, as an active area overlapping a light detecting sensor positioned on a rear surface of a display panel has a low resolution and includes a plurality of holes that an insulating layer is etched, thus the display device that the light detecting sensor detects an object positioned in front of the display panel can be provided. Furthermore, as a light blocking pattern is disposed on an area overlapping an inclined surface inside of the hole, thus a distortion of a light entered to the inclined surface inside of the hole can be prevented and a detecting performance of the light detecting sensor positioned on the rear surface of the display panel can be improved.

Display device with multi-resolution

A touch display device is disclosed. The touch display device includes a touch electrode and a touch routing line that are disposed on an area that is different from an area where a spacer is disposed. Thus, a touch sensing function can be provided in the touch display device while reducing an influence that a touch sensor structure affects a viewing angle of an image.

Touch display device including spacers

Embodiments of the present disclosure are related to a touch display device. As a shape of a touch electrode adjacent to a boundary of an active area is implemented according to an arrangement structure of a light-emitting area of a subpixel, a touch sensing structure can be disposed to be suitable to an image display structure of a display panel.

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.

Touch display device and touchscreen panel

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.

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.

Embodiments of the present disclosure are related to a touch display device that includes a touch sensor. The touch sensor has a touch sensor structure that prevents or at least reduces a defect of a touch routing line that electrically connects a touch electrode and a touch pad. The defect is prevented or at least reduced due to a reduction of a height difference between a dam disposed between an active area and a pad area and a peripheral area thereof.

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.

In a touch display device, an electrode pattern is arranged on an area overlapping a touch electrode and a touch routing line which are disposed on an active area. Thus a touch sensor structure can be implemented while improving visibility of a display panel.

Embodiments of the present disclosure are related to a touch display device. By differentiating a cutting shape of a boundary of a portion constituting a touch electrode or a touch routing line and a cutting shape of a boundary of a portion constituting a dummy electrode, a repair of a touch sensor structure can be performed easily in a process implementing the touch sensor structure in a display panel.
