Embodiments of the disclosure may insert a break period when the gate line is not driven, such as a blank period, of an active period of a frame period and perform touch sensing, driven in the same manner as touch sensing driven in the blank period, in the break period, thereby reducing the influence of display driving on touch sensing and enhancing touch sensing performance.

Touch display device

An electroluminescent display is disclosed. The electroluminescent display includes an electroluminescent element disposed in a display area of a substrate, an encapsulation unit disposed on the electroluminescent element, a first mesh electrode layer disposed on the encapsulation unit, an insulating layer covering the first mesh electrode layer, and a second mesh electrode layer disposed on the insulating layer. The first mesh electrode layer includes a first mesh electrode and a second mesh electrode separated from the first mesh electrode. The second mesh electrode layer includes a third mesh electrode extended in a first direction and a fourth mesh electrode extended in a second direction intersecting the first direction through the first mesh electrode intersecting the third mesh electrode.

Electroluminescent display including touch sensor

Embodiments of the present disclosure are related to a touch display device, in a structure that a touch electrode line is disposed to be divided on a plurality of sub-areas included in an active area, by synchronizing a driving of the touch electrode line adjacent to a boundary of the sub-area, or by performing a differential sensing processing by sharing a touch sensing signal detected from the touch electrode line, thus an accuracy of a touch sensing for an area adjacent to the boundary of the sub-area can be improved.

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.

Touch display device and touch driving circuit

The disclosure is related to a touch display device, a shield electrode separated from a common electrode of a light-emitting element can be disposed on an area overlapping a touch electrode under an encapsulation layer, and a shield driving signal corresponding to a signal supplied to the touch electrode can be supplied to the shield electrode. Thus, the shield electrode prevents or at least reduces formation of a parasitic capacitance between an electrode or a signal line for a display driving and the touch electrode, and a touch detection performance can be improved by implementing a noise blocking function by the shield electrode.

Disclosed is a display device integrated with a touch sensor that may include a plurality of gate lines and a plurality data lines crossing each other; a plurality of pixel electrodes between the data lines; a plurality of touch/common electrodes arranged in a first direction and a second direction that cross each other, each of the plurality of touch/common electrodes overlapping at least one pixel electrode; 1-1 routing wires connected to 1-1 touch/common electrodes; 1-2 routing wires connected to 1-2 touch/common electrodes; 2-1 routing wires connected to 2-1 touch/common electrodes; and 2-2 routing wires connected to 2-2 touch/common electrodes.
