ABSTRACT
In the new century, the photoelectron industry wide
attention by society, LED display as an important means of
information dissemination, has been widely used in indoor and
outdoor services, content and services needed publicity purposes
in public places. In particular, there is no projector in place,
rotating LED's superiority reflected very clearly in today's
highly developed economy markets, creative, application wide,
the diversion of convenient, attractive information
dissemination system is extremely important! The twenty-first
century is the era of digital communication, with the LED
technology and the popularity of digital LED display is widely
used. Traditional LED display to effect mostly flat, circular
rotating LED display design is the use of temporary stay in the
human visual effects, high-speed motor to drive the LED array
rotation, the formation of 360-degree circular display can stand
on any point of view, complete without viewing dead, to give
people a new visual experience. The design is based on STC89C52
MCU, using separate LED, driven by DC motor rotation, can form
three-dimensional effect, make it more colorful, more spectator,
can be widely used in homes, businesses and public places.
View traditional LED display single, larger and larger
number of required characteristics of light-emitting diode, LED
display of motor driven circular array of high-speed rotation
of the display, to 360 full view, in the same amount of
information displayed on the lower product volume and reduce on
the use of LEDs, the design can often facilitate the
transformation of a content, can be portable, high information
content, low cost, simple structure, the information broadcast
system, the rotating LED display.
