1. Overview
Multi-screen processor, also called multi-screen display controller, is a dedicated image
processing device based on certain operating system platform and offering multi-screen
driving function to perform remote display and control on various types of signals through
different modes. Generally speaking, it is a computer system with power functions.
However, different from the ordinary computer system, it is also a powerful image server
system.
When there is no multi-screen processor, the signals from the signal sources can still be
directly input to the digital display wall for display, but the display capacity of the digital
display wall system is completely subject to the display capacity of the display wall. The
application of the multi-screen processor can realize the processing and conversion of
signals before they are input to the digital display wall, thus greatly expanding the display
functions, application scopes and application methods of the display wall. It is a component
of great significance in the digital display wall system.
