摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present embodiments generally relate to a display panel and a display device which may recognize touch. A display panel is provided in which a touch sensor and a touch line are disposed in an active area in which a part of an outer edge of the touch line is curved to correspond to a curved shape of the active area in the display panel so that the touch sensing is allowed in display panels having various shapes. Further, a touch display device is provided in which an open area is located between two adjacent touch lines disposed on the display panel so that touch sensing is allowed also in the display panel including an open area such as a hole or a notch.

摘要： A touch display device and a touch display panel are provided. The touch display panel includes a bend area adjacent to the periphery of the touch display panel, and touch lines disposed in the bend area have zigzag shapes that extend at angles with respect to a bend axis about which the bend area is bent. A first dielectric layer includes a compensation pattern that is located in the bend area and includes an opening that extends in a direction parallel to the bend axis. A second dielectric layer protrudes into the opening of the compensation pattern in a depth direction. During bending of the bend area, this configuration disperses force applied to portions of the touch lines and the dielectric layers in the bend area. This can consequently prevent both cracking due to bending and moisture permeation due to cracks.
