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 display device according to an embodiment comprises a substrate including a display area where subpixels are disposed and a non-display area outside the display area, each of the subpixels including an anode electrode, a light emitting layer, and a cathode electrode for displaying an image, an encapsulation layer positioned on the substrate, a shielding electrode positioned on the encapsulation layer, an intermediate organic layer positioned on the shielding electrode, a touch electrode positioned on the intermediate organic layer, a touch insulation layer positioned on the touch electrode, a shielding electrode line electrically connected with the shielding electrode, and a shielding electrode pad electrically connected with the shielding electrode line. The shielding electrode receives a voltage through the shielding electrode pad.

Display device

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.

Touch display device

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 display device includes a substrate including a display area and a pad area; a thin film transistor in the display area; a light emitting film layer on the thin film transistor; an encapsulation layer on the light emitting film layer; a touch buffer layer on the encapsulation layer; a bridge, first touch electrodes and second touch electrodes disposed on the touch buffer layer; a touch insulating film disposed between the bridge and the first touch electrodes and the second touch electrodes; a touch pad in the pad area; a touch sensing line connected to the first touch electrodes; and a touch driving line connected to the second touch electrodes, wherein at least one of the touch sensing line and the touch driving line is provided on a side surface of the encapsulation layer.

Display device including touch sensor and method of manufacturing the same

The present disclosure provides a touch display device having a structure in which at least one touch electrode is disposed on an encapsulation layer, and including a noise shielding layer located between a layer in which the signal line under the encapsulation layer is disposed and a layer in which at least one light emitting element is disposed. The noise shielding layer can block coupling between the signal line and an electrode of the light emitting element, and reduce or prevent a fluctuation in the voltage of the electrode of the light emitting element from causing noise to occur in a touch sensing signal detected by the at least one touch electrode on the encapsulation layer.

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.

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.

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.

According to embodiments of the disclosure, a transparent touch display device may comprise a substrate including a display area displaying an image and a non-display area not displaying the image, the display area including a plurality of light emitting areas and a plurality of transmissive areas and a touch sensor including a touch sensor metal disposed while avoiding the plurality of light emitting areas and the plurality of transmissive areas and a transparent electrode disposed in the transmissive areas and electrically connected with the touch sensor metal. The transparent touch display device according to embodiments of the disclosure may provide high transmittance and high touch sensitivity.

Transparent touch display device

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.
