Embodiment Construction

[0025] While the embodiments of the present invention allow various modifications and alternative forms, specific embodiments thereof have been shown in the drawings as examples and described in detail herein. However, it should be understood that this description is not intended to limit the invention to the disclosed specific form, but to make the invention cover all modifications, equivalents and substitutions of the embodiments of the invention as defined in the claims.

[0026]As mentioned above, acoustic touch screen technology is superior in detecting the position of an object touching the touch screen substrate (hereinafter referred to as "position sensing"), but generally cannot sense whether the object remains in continuous contact with the substrate or whether the object is being held against the substrate. against the substrate (hereinafter referred to as "hold-release sensing"). To remedy this problem, a simplified capacitive sensing structure has been combined wi...

Abstract

The present invention relates to a simplified touch screen system capable of sensing when an object is in direct or indirect continuous contact with a transparent substrate of the touch screen system and determining the position (eg, X coordinate, Y coordinate) of the object relative to the transparent substrate. Touch screen systems use capacitive technology to sense whether an object is in contact with the transparent substrate, and acoustic sensing technology to determine the location of the object in contact with the transparent substrate. Touch screen systems require a small amount of shielding and isolation layers to be deposited on the transparent substrate, in part because touch screen systems utilize a bezel associated with the underlying display to provide shielding from electromagnetic radiation emitted by the display.

Description

Background technique [0001] Many electronic devices use touch screens or touchpads to detect the presence and location of contact, typically by a finger, hand, or other object, within the display area of ​​the electronic device. Such electronic equipment includes mobile phones, network appliances, portable game consoles, portable readers, music players, navigators, home appliances, automation and electronic control equipment, notebook computers, television screens, and the like. A touchscreen allows direct interaction with what is displayed on the screen where information is displayed, rather than indirect interaction through a mouse or a separate touchpad. The touch screen also allows this interaction without requiring any intermediary device such as a stylus that must be held in the user's hand. [0002] There are some touch screen technologies and from these various technologies, the acoustic touch screen technology has become a durable and precise technology that works ev...
