Embodiment Construction

[0025] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0026] refer to figure 1 , discloses a transparent touch screen sensor 10 . Sensor 10 may be implemented in various electronic devices with displays, including but not limited to mobile computers, computer monitors, mobile phones, personal digital assistants (PDAs), and kiosks. The sensor 10 is configured to detect a touch by measuring a localized pressure exerted on a display area such as a touch screen. Advantageously, sensor 10 allows analysis of a third dimensional input, namely force, in addition to time and position input, enabling a whole new range of applications.

[0027] In one embodiment, the sensor 10 includes a force-sensing transparent polymer-conductor composite (...

Abstract

A transparent force sensor for use in touch panel displays (touch screens) and method for fabricating the same are disclosed. The transparent force sensor is capable of detecting touch by measuring local pressure applied by a touch input to a display area of the touch screen.

Description

[0001] Cross References to Related Applications [0002] This nonprovisional application is related to co-pending U.S. Application Serial No. 12 / 052,365, filed March 20, 2008, entitled "Transparent Pressure Sensor and Method for Using," which The entire contents are incorporated herein by reference. technical field [0003] The present disclosure relates to computing device input arrangements, and more particularly, to transparent force sensors and methods of manufacture for touch panel displays. Background technique [0004] Today, in many electronic devices such as portable communication devices, touch panel displays (touch screens) present information to the user and also receive input from the user. Touch screens are especially useful in portable communication devices where other input devices such as keyboards and mice are not readily available. [0005] There are many different types of touch sensing technologies in use today, including capacitive, resistive, infrare...
