STRUCTURE FOR PIXELATED SELF-CAPACITANCE
First Claim
1. A touch screen having layers, the touch screen comprising:
- a substrate upon which the layers of the touch screen are disposed;
a touch region including a touch pixel electrode, a first display sub-pixel and a second display sub-pixel;
a sense connection coupled to touch sensing circuitry, the sense connection disposed between the touch pixel electrode and the substrate; and
an intermediate connection disposed between the touch pixel electrode and the sense connection, the intermediate connection being electrically coupled to;
the sense connection at the first display sub-pixel, andthe touch pixel electrode at the second display sub-pixel.

Abstract
A touch screen having layers. The touch screen can include a substrate upon which the layers of the touch screen are disposed, and a touch region including a touch pixel electrode, a first display sub-pixel and a second display sub-pixel. The touch screen can also include a sense connection coupled to touch sensing circuitry. An intermediate connection can be disposed between the touch pixel electrode and the sense connection, and can be coupled to the sense connection at the first display sub-pixel and the touch pixel electrode at the second display sub-pixel. In some examples, the sense connection can be disposed at least partially underneath a structure in the first display sub-pixel, such as a data line. In some examples, the intermediate connection can be comprised of a same material type as a structure in the first display sub-pixel, such as a gate line material.
