System and method for driving and receiving data from multiple touch screen devices
First Claim
1. An apparatus for driving a plurality of touch screen devices from a single graphics signal, comprising:
- a general-purpose computer configured to provide a graphics signal of a particular display resolution, the graphics signal including a plurality of graphics frames;
a display segmentor configured to divide a first portion of each graphics frame of the graphics signal into a plurality of pixel groups, while a second portion of each graphics frame is not a part of any pixel group of the plurality of pixel groups, each pixel group associated with a particular touch screen device of the plurality of touch screen devices, the display segmentor further configured to generate an individual graphics signal from each pixel group of the first portion of each graphics frame but not from the second portion of each graphics frame, each individual graphics signal having a display resolution that is lower than the particular display resolution; and
one or more interfaces configured to transmit each individual graphics signal to a different touch screen device of the plurality of touch screen devices, and to receive coordinates from each touch screen device corresponding to user touches on the respective touch screen device,wherein the display segmentor is further configured to map the coordinates received from each touch screen device to coordinates of a single screen space by adding offset values to the coordinates from at least some of the touch screen devices and to provide the coordinates of the single screen space to the general purpose computer.

Abstract
In one embodiment, multiple touch screen devices are driven from a graphics signal. A general-purpose computer provides a graphics signal of a particular display resolution. A display segmentor is configured to divide each graphics frame of the graphics signal into a plurality of pixel groups, each pixel group associated with a particular touch screen device of the plurality of touch screen devices. The display segmentor is further configured to generate an individual graphics signal from each pixel group, each individual graphics signal having a display resolution that is lower than the particular display resolution. One or more interfaces transmit each individual graphics signal to a different touch screen device of the plurality of touch screen devices.
