TOUCH DETECTION
First Claim
1. An apparatus comprising:
- a first touch screen comprising a plurality of first touch sensors formed as a first grid of rows and columns;
a second touch screen comprising a plurality of second touch sensors formed as a second grid of rows and columns;
a first processor configured to detect touch areas by scanning through the first touch sensors in a predetermined order along the rows and columns;
a second processor configured to detect touch areas by scanning through the second touch sensors in a predetermined order along the rows and columns; and
a controller configured to cause the first and second processors to scan the first and second grids synchronized such that when the first and second touch screens are arranged side by side, neighboring first and second touch sensors are scanned substantially simultaneously.

Abstract
An apparatus with a first and second touch screen, where the first touch screen has a plurality of first touch sensors formed as a first grid of rows and columns and the second touch screen has a plurality of second touch sensors formed as a second grid of rows and columns. A first processor detects touch areas by scanning through the first touch sensors in a predetermined order along the rows and columns. A second processor detects touch areas by scanning through the second touch sensors in a predetermined order along the rows and columns. A controller causes that the first and second processors scan the first and second grids synchronized such that when the first and second touch screens are arranged side by side, neighboring first and second touch sensors are scanned substantially simultaneously.
