Glass Touch Screen
First Claim
1. A touch sensitive screen for an electronic device, said electronic device having a control assembly structured to provide a video input to a display assembly input/output assembly and to receive sensor output from a sensor assembly, said touch sensitive screen comprising:
- a display assembly having an input/output assembly and an LCD panel, said input/output assembly structured to receive a video input from said control assembly and to produce an image on said LCD panel;
said LCD panel having an active area and a viewing area;
a sensor assembly having an output device and a plurality of detectors;
each said detectors structured to detect an object adjacent to said detector and to provide a signal to said output device;
said detectors disposed on said display screen in a pattern having at least a first portion and a second portion;
said detector pattern first portion having a spare dispersion of detectors and disposed over said LCD panel active area;
said detector pattern first portion having a dense dispersion of detectors and disposed over said LCD panel viewing area; and
said sensor output device structured to receive each said sensor signal and to provide a sensor output to said control assembly, said sensor output having data indicating the position of said adjacent object relative to said LCD panel active area and viewing area.

Abstract
These needs, and others, are met by at least one embodiment of the disclosed invention which provides for a touch sensitive screen for an electronic device wherein there is a sparse pattern of sensors disposed within the active area and a dense pattern of sensors disposed within the viewing area. In this configuration, the pixels in the active area may have a larger aspect ratio and provide a more pleasing image while the dense sensors disposed within the viewing area provide more accurate touch sensitivity. Further, the software, or other electronics, used to create the image, may be structured to position menus or other selectable images adjacent to the viewing area. Similarly, certain images, such as icons, can be programmed to be displayed directly under the sensors in the active area. Generally, this configuration provides for the best of both worlds; a bright, clear image with some touch sensitivity in the active area and a sensitive sensor grid in the viewing area where there are no pixels.
