## Background
CLAIM OF PRIORITY
The present application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Ser. No. 61/580,926, filed on Dec. 28, 2011, which is incorporated herein by reference in its entirety.


TECHNICAL FIELD
This document relates generally to hearing assistance systems and more particularly to a hearing aid including a flexible display integrated with a touch sensor.
BACKGROUND
Hearing aids are used to assist patients suffering hearing loss by transmitting amplified sounds to ear canals. In one example, a hearing aid is worn in and/or around a patient's ear. Patients prefer that their hearing aids are minimally visible or invisible, do not interfere with their daily activities, and easy to control (such as turning on/off and adjusting sound volume). A user interface incorporated onto a hearing aid provides the patient with some control of the hearing aid operation, such as turning the hearing aid on/off and adjusting sound volume. The functionality of such a user interface is limited by design constraints such as the limited space and power available from the hearing aid. Thus, there is a need for a user interface providing a user with improved controllability, ease of use, and/or appearance of a hearing aid while being compatible with power and other constraints of the hearing aid.
SUMMARY
A user interface incorporated onto a hearing aid includes a flexible hybrid component integrating a touch sensor into a bendable display. The touch sensor, such as a capacitive sensor, includes one or more sensor elements allowing a user to control operation of the hearing aid by touching. The bendable display presents information related to the operation of the hearing aid.
In one embodiment, a hearing aid includes a hearing aid circuit, a hearing aid housing, and a user interface.
