The disclosure provides a display device and a terminal. The display device includes a display panel, a touch layer, a detecting circuit, and a connecting line. The display panel includes a display area, a first through hole, and a buffer area. The touch layer is provided with a plurality of touch electrodes, and a second through hole is defined in an area of the touch layer corresponding to the first through hole. The detecting circuit is disposed in the buffer area and is configured to detect quality of the first through hole. The connecting line is formed in the touch layer and is configured to connect the detecting circuit to an external circuit. Quality of an area of the display panel where a hole is defined is detected.

Display device and terminal

A touch substrate for a touch screen includes a touch layer. The touch layer includes a first electrode and a second electrode. The first electrode includes a first protrusion and a first dummy electrode. The second electrode includes a second protrusion and a second dummy electrode. Adjacent two first protrusions or adjacent two second protrusions are spaced apart by a size of at least one sub-pixel.

Touch substrate and touch screen

Disclosed is a touch electrode and a touch display device. The touch electrode comprises a plurality of first electrode chains and second electrode chains intersecting with the first electrode chains. Each of the first electrode chains comprises a plurality of first electrodes and a first connecting portion. Each of the second electrode chains comprises a plurality of second electrodes and a second connecting portion. Each of the second connecting portions comprises a connecting island located between the two adjacent second electrodes, at least one first connecting bridge electrically connecting the connecting island and one of the two adjacent second electrodes and at least one second connecting bridge electrically connecting the connecting island and the other of the two adjacent second electrodes. By means of the present invention, the length of the connecting bridge can be reduced and the breaking of the connection can be prevented.

Touch electrode and touch display device

The present disclosure provides a display panel and a display device, wherein the display panel includes at least one of the plates of the storage capacitor provided with a charging element. By providing the charging element, charging the storage capacitor when the storage capacitor is discharged, so that the charge of the storage capacitor tends to stable or keep stable. That is, the voltage supplied from the storage capacitor to the driving transistor is ensured to constant, so that the luminance of the pixel is not distorted.

Display panel and display device

A metal mesh touching sensing electrode assembly includes a metal mesh, first electrode columns, and second electrode rows. The first electrode columns are disposed on the metal mesh. Each first electrode column includes first electrode units which are mutually connected. Each of the first electrode units includes a first outer frame, first connection patterns, and first boundary patterns. The first connection patterns include a first T-shaped portion and a first linear portion. Each second electrode row includes second electrode units which are mutually connected with each other. Each second electrode unit includes a second outer frame, second connection patterns, and second boundary patterns. Each second connection pattern includes a second T-shaped portion and a second linear portion. The first electrode units and second electrode units of the metal mesh touching sensing electrode assembly have complicated patterns to prevent a visibility issue of an unexpected visual strip effect.
