| Title: |
Smart Light Emitting Diode Cluster and System |
| Abstract: |
A smart light emitting diode cluster and system includes a central
processing unit (CPU) and a plurality of LED cluster strings, each
comprising a plurality of LED cluster connected in series. Each LED
cluster includes an LED drive circuit and a plurality of LEDs. The CPU
receives external input image signal, and then desired control signal and
image data are sent to the LED cluster strings by appropriate processing.
The control signal is used to switch the LEDs in the cluster to generate
desired image and related color variation. The control signal and image
data are transferred to the next LED cluster by the present LED drive
circuit. In this manner, the control signal and image data are
progressively transferred from the first to the last cluster so that a
whole image with color variation can be displayed by all the LEDs in the
system.
