Over the last decade, we have integrated digital signage into our professional signage solutions, the core of our business. Holographic 3D LED Visual Fan is the latest product from Hardy Signs in the digital signage provision.

With Persistence of Vision (POV) technology, Hologram 3D LED Visual fan is a kind of display which can present holographic 3D visual effect through a series of high-density LED rotating objects imaging.

 

 

History and Development

According to Zharkiy (‘’History of the holography’’): ‘’The concept of a hologram was first introduced by the British-Hungarian scientist Dennis Gabor in 1947. Gabor came up with the term hologram from the Greek word holos (meaning ‘whole’) and gramma (meaning ‘message’).’’

‘’Laser technology which serves as the basis of some modern-day holographic displays, was initially developed by Russian scientists Nikolay Basov and Alexander Prokhorov and American scientist Charles Hard Townes in 1960. The invention of laser was a crucial step into the development of holographic displays. Prior to this, light sources available were not truly ‘coherent’.’’

‘’In 1972, Lloyd Cross developed the integral hologram by combining white-light transmission holography with conventional cinematography to produce moving 3-dimensional images. Sequential frames of 2-D motion-picture footage of a rotating subject is recorded on holographic film. When viewed, the composite images are synthesized by the human brain as a 3-D image.’’

In 2005, the University of Texas developed the laser plasma display, which is considered the first real 3D holographic display.

In 2013, the Massachusetts Institute of Technology’s researchers predicted that holographic displays will be entering the mass market during the next 10 years, as all the technology necessary was ready since then.

Holographic 3D LED Visual Fan

Holographic 3D LED Visual fan is the first holographic product that we’re adding to our signage solutions.  Similar to Lloyd Cross’ research and development, our product consists of sequential frames of 2D and 3D motion-picture and video footage of a rotating digital display recorded on a holographic film. The human brain perceives this as a 3D display.

You can install these displays on a wall or a stand and control the software and content via any normal PC or Wi-Fi. Formats recognised include jpeg, gif, mp4, avi, apeg, etc.

In the near future, we aim to integrate other new holographic technologies that would help our customers in all sectors boost their products’ visibility.

Any companies and sectors can make use of these technologies, whether that is in their shops, offices, or exhibition stands. We’re publishing the guide for this in the next few days.
