Rotating LED fan display technology
Taiwan-based Polo Tech, which claims a patent on rotating LED fan display technology, has plans for a USB-programmable model, although the release date is undecided, company representative Alice Wang said at Computex in Taipei. Users will be able to use an internal USB connection and software to change the fan display in real time to show their name, or any other text or simple graphics.
The fans generate the display with a rotating stick of circuit board with a vertical line of LEDs on it. This is mounted on the fan’s axis, and spins as the fan spins. Polo Tech’s driver IC can also handle simple animation, and even colour changes, given suitable LEDs. The IC also handles the precise timing calculations required to keep the display steady.

The World Largest 3D LED Display
The “Electrotechnische Vereeniging”, the association for students of electrical engineering from the Delft University of Technology (TU Delft), will reveal the world’s largest 3D-display Sunday 23rd of April. The display measures 8 metres in width, 4 metres in height and 2 metres in depth and consists of a matrix of 8.000 LEDs with table tennis balls around them. This stunt is being organised because of the celebration of the 100th anniversary of the “Electrotechnische Vereeniging” (ETV). The display will be revealed on Sunday at 9.00 pm local time on the ‘Markt’ in Delft.
It will be possible to send text messages to the MatriXX during the times it is operating. Send your sms/text to +31 (0) 6 24 171 797 . It will be displayed during the next sms display time slot. Threats, rude language etc will be filtered.

The Cubatron - LED PingPong 3D Display
The Cubatron is the world’s largest true 3D color graphics display (until the BRC is built in August 2006). It is 8×8x8 feet in size. It consists of 729 voxels (3D pixels) arranged in a 9×9x9 matrix, spaced 10 inches apart from each other. Each voxel is a 40mm diameter ball that can be independently set to display a 21-bit RGB color. The entire display can be updated about 30 times per second. The voxels “float” in space so that the viewer can see through the cube and have a view of most of the voxels from any position.
There are 729 voxels. Each one has a microcontroller on it. There are 27 strings of 27 voxels. The voxels on each string have an address of 1 through 27. They are sent commands using a special synchronous protocol which consists of a frame which contains RGB data for each of the 27 voxels on the string. A frame is sent on every string about 30 times per second. The voxels take the last RGB value they got and PWM the RGB LED to display the proper color.
A PC running FreeBSD generates the patterns to display. The PC converts the RGB data into the 27 streams of data to be sent to each string of voxels. It sends this data across an ethernet connection to an ethernet printer server. The printer server’s parallel port outputs data to the voxel driver board. The voxel driver board has a PIC18F452 which demuxes the incoming data and sends it out to the 27 voxel strings while maintaining proper timing for the synchronous protocol. The Cubatron requires 100K bytes of data per second.

3D Display Cube
The 3D Display Cube encourages the viewer to think about the limitations of current display systems and the representation of spatial data. To be able to recreate spatial data will allow us to display ideas closer to the way we envision and experience them; with depth. The 3D Display Cube was hand built and constructed from one thousand individually controllable LEDs soldered into a 10×10x10 freestanding matrix.
Each LED acts as one spatial pixel and can be refreshed at a rate of over 60 fps creating a low resolution 3D television. The Cube has an input device (serial input) that allows data to be sent to the cube to manipulate the 3D data live. The display unit can then be hooked up to a camera for live video input , or to a sound module chip to take in live audio input.
