Benefits of technology

[0008]Accordingly, it would be advantageous to extend the usable lifespan of a touch screen assembly without necessitating replacement of the touch screen assembly itself, or of the device using the touch screen assembly. Additionally, while meeting the above stated need, it would also be minimize the cost associated with extending the usable lifespan of a touch screen assembly.

Problems solved by technology

One problem associated with touch screen assemblies occurs when they are subject to temperature fluctuations.
For example, when moved from a cold environment (e.g., outdoors in winter) to a warmer environment (e.g., indoors) expansion of the size of touch screen assembly 100 may result in inadvertent activating of the resistive digitizer mechanism.

Abstract

Embodiments of the present invention recite a method and system for extending the lifespan of a touch screen assembly. In one embodiment, a signal is received indicating an input pressure is being applied to a touch screen assembly. It is then determined that the input pressure comprises a valid input event and the coordinates of the valid input event are received from the touch screen assembly.

Description

RELATED APPLICATIONS[0001]The present application benefits from provisional U.S. application Ser. No. TBD, filed Apr. 28, 2006, titled Method and System for Extending the Lifespan of a Touch Screen Assembly, by John Paul Harmon, Chris Peskin, James W. Pearson, and Robert Puckette, assigned to the assignee of the present application, attorney docket number TRMB-1719.PRO, and incorporated by reference in its entirety herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments in accordance with the present invention generally pertain to devices which utilize a touch screen assembly that may be activated by finger touch or by stylus pressure. More particularly, embodiments of the present invention are related to extending the lifespan of touch screen assembly that may be activated by pressure.[0004]2. Related Art[0005]Flat panel resistive touch screen displays are used in numerous electronic products such as wrist watches, hand calculators, cell phones, and PDA's...
