Abstract
The present application provides a touch substrate and a touch screen. The touch substrate 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 a size of at least one sub-pixel apart.
Claims18
A touch substrate, comprising a substrate and a touch layer formed on the substrate, wherein the touch layer comprises:
- at least one first electrode group arranged along a first direction comprising at least two first electrodes arranged along a second direction and sequentially connected to each other, wherein any of the first electrodes comprises at least one first connection region outside the first electrodes, and any of the first connection regions comprises at least one first protrusion;
- and
- at least one second electrode group arranged along the second direction comprising at least two second electrodes arranged along the first direction and sequentially connected to each other, wherein any of the second electrodes comprises at least one second connection region outside the second electrodes, and any of the second connection regions comprises at least one second protrusion;
- wherein the first protrusion is disposed between two adjacent second protrusions, the second protrusion is disposed between two adjacent first protrusions, the first connection region and the second connection region are engaged with each other to form a connection portion of the first electrode and the second electrode;
- wherein at least one first dummy electrode disposed in any of the first electrodes, the first dummy electrode is uniformly distributed in the first electrode, and the first dummy electrode is insulated from the first electrode;
- wherein at least one second dummy electrode disposed in any of the second electrodes, the second dummy electrode is uniformly distributed in the second electrode, and the second dummy electrode is insulated from the second electrode;
- and
