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 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 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; 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.

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.
