A touch display device drives only some of a plurality of common electrodes disposed in a display panel as a touch electrode, so that an increase of lines and a reduction of an aperture ratio according to implementing a function of a touch sensing can be minimized, and as adjusting a total resistance and a resistance distribution according to locations between the common electrode driven as the touch electrode and the common electrode not driven as the touch electrode same or similarly, an abnormality of a display driving due to partial driving the plurality of common electrodes as the touch electrode and provide the function of the touch sensing can be prevented.

Touch display device

Disclosed are an organic light emitting display panel and an organic light emitting display device including the same, in which a pixel driving circuit of a subpixel, sharing an anode with a white subpixel, of subpixels configuring a unit pixel is disconnected from the outside of the subpixel.

Mitigating shorted pixels in an organic light emitting display panel

Discussed is a panel including: a plurality of pixels, each pixel including a plurality of sub-pixels; and a single circuit part, wherein at least one of the plurality of sub-pixels in the each pixel has a plurality of emitting parts that are all light emitting, and wherein the single circuit part is connected to the plurality of emitting parts to drive the plurality of emitting parts to all emit light.

Organic light emitting display panel, organic light emitting display device, and repairing method of the same

The present exemplary embodiments provide a touch display device which connects a touch driving circuit and a plurality of touch sensors using a plurality of dummy pixels disposed on a display panel to recognize touch event of a user. When the touch wiring line is implemented, the same material as the pixel electrode or the source line included in the plurality of dummy pixels is used so that a separate process for implementing the touch wiring line is not necessary. Further, in a pixel structure in which one data line is disposed for every two pixels, the source line is disposed in a region where the data line is not disposed to be used as a touch wiring line. Therefore, the touch recognizable area may expand as compared with a case using a pixel metal.
