ABSTRACT:
A large screen display apparatus comprises a plurality of displays constituting a single large screen for displaying an object. The object is formed on the basis of screen data which is generated by a screen data generating section. Each of the displays is provided with a local data generating section for converting a coordinate of the screen data from the screen data generating section into a coordinate of a local coordinate system peculiar to the individual displays. Because the local data generating sections, each provided to one respective display, executes coordinate conversion to the screen data, it is possible to reduce load to the screen data generating section, and to thereby provide a display performance with a rapid response.
