Abstract
Light-emitting diode (LED) displays are currently
experiencing a growing interest in many applications
such as publicity, mass shows, etc., because of their
high performance in terms of component reliability,
brightness, power efficacy, modularity and scalability.
However, the complexity of the control architecture of
the present designs, based on current drivers, is the
biggest obstacle to a significant cost reduction and
massive spreading of this technology. In this paper, a
new control architecture based on D-type flip-flops
registers (HC logic) is presented. This design reduces
in a significant way the cost and complexity of the
large LEDs displays. It works as a write only memory on
the basis “it is seen what is
saved”. This design is adequate for variable
brightness screens on multicolor displays.
