INTEGRATED TOUCH SCREEN
First Claim
1. A touch screen having an integrated display, the touch screen comprising:
- a plurality of display pixels, each having a corresponding circuit element;
a plurality of first lines, each including at least a first plurality of circuit elements of the display pixels connected to one another along both a first direction and a second direction;
a plurality of second lines including at least a second plurality of circuit elements of the display pixels; and
a plurality of touch regions, each touch region formed by ones of the first plurality of circuit elements and ones of the second plurality of circuit elements that are adjacent the ones of the first plurality of circuit elements.

Abstract
Displays with touch sensing circuitry integrated into the display pixel stackup are provided. 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.
