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.
