Integrated Touch Screen
First Claim
1. A stackup of a plurality of display pixels, the stackup comprising:
- a first layer of conductive material;
a second layer of conductive material;
a third layer of conductive material including first conductive lines in a first direction, each of the first conductive lines including a plurality of first line portions extending through plural display pixels and separated from each other by disconnections; and
second conductive lines in a second direction transverse to the first direction, each of the second conductive lines including a plurality of second line portions extending through plural display pixels and separated from each other by disconnections,wherein circuit elements of the display pixels in a first region are electrically connected together in the first direction by a first plurality of the first line portions, the circuit elements of the display pixels in the first region are electrically connected together in the second direction by a first plurality of the second line portions, and a plurality of display pixels in the first region are contact pixels that include contact points that electrically connect the circuit elements of each of the contact pixels with a conductive pathway that extends from the first region into a second region of display pixels without electrically connecting to circuit elements of display pixels in the second region.

Abstract
Displays with touch sensing circuitry integrated into the display pixel stackup are provided. Circuit elements, such as touch signal lines, such as drive lines and sense lines, grounding regions, in the display pixel stackups can be grouped together to form touch sensing circuitry that senses a touch on or near the display. An integrated touch screen can include multi-function circuit elements that can operate as circuitry of the display system to generate an image on the display, and can also form part of a touch sensing system that senses one or more touches on or near the display. The multi-function circuit elements can be, for example, capacitors in display pixels that can be configured to operate as storage capacitors/electrodes, common electrodes, conductive wires/pathways, etc., of the display circuitry in the display system, and that may also be configured to operate as circuit elements of the touch sensing circuitry.
