1. An apparatus comprising:
- a display including an array of non-capacitive, image producing display pixels formed in an integrated circuit substrate;
a plurality of capacitive sensors distributed amongst the display pixels and embedded within the display and integrated with said pixels in said substrate, the sensors to detect capacitive coupling between an object placed in proximity to the display pixels and a sensor;
a transimpedance amplifier (TIA);
a capacitance detection element (CDE) coupled to the TIA; and
a buffer coupled to the CDE.

Abstract
Apparatus, systems including an electrical touch screen sensor and methods for implementing an electrical touch screen sensor are disclosed. For example, an apparatus is disclosed including a display having an array of display pixels and a plurality of sensors distributed amongst the display pixels and embedded within the display, where the sensors act to detect changes in capacitance associated with objects placed in proximity to the display pixels. Other implementations are also disclosed.
