CPU AND LED module for displaying pictures

• CLIENT: ARATRON TECHNOLOGIES s.r.o.

Device for displaying pictures and performing light shows using LED stripes and CPU module. These modules are combined inside a transparent tube and connected to a battery. The design is modular, therefore it is possible to combine more LED modules to create longer display area. Pictures for the show are stored inside the CPU module, which is dividing them into separate lines. These lines are then being displayed one-by-one using the LED lights on the LED module. To achieve that, these lights are blinking thousands of times per second and when the transparent tube is being quickly rotated in a circle, the eye percieves the blinking of the LED lights as a whole circular picture. It is caused by the effect known as persistence of vision and it is a similar effect to seeing aircraft propeller as a solid circle instead of separate blades when in motion.

The device has record-breaking parameters:

• 160 LED lights on a single module (80 on each side), minimal distance between LEDs

• 180 degrees light emission angle

• LED blinking rate from 2600 Hz – 4000 Hz

• 10 bit colours

• Powerful RISC CPU

• 256 MB memory

• Image stabilisation (world´s first)

• High-speed USB 2.0, USB charging

• Wireless synchronization

• Built-in remote controller
