4K UHD TV Visualization Applications

4K UHD TV (ULTRA HIGH DEFINITION) is the next iteration of technology coming to the consumer TV markets. HD was good, 3D was interesting, but is 4K now necessary? While the industry is debating whether or not this is a “must have” technology for the living-room – it is a great solution for advanced visualization applications.

Consider this – many businesses are centered around visualizing complex information, such as seismic imaging, geospatial mapping and analysis, automotive simulation, and other scientific and technological innovators. The more complex the information, the more beneficial collaborative analysis becomes. The best collaboration occurs when everyone can see and discuss the information at the same time. Since 4K TV adds high resolution into large format displays – it is a great fit for visualization rooms.

4K UHD TV Overview

The following video gives an overview of 4K UHD TV technology:

While the current focus of this technology is consumer living rooms for movie watchers, it can also be applied to business visualization solutions. Computer monitors have traditionally had a maximum resolution around the HD range (1920×1080), and traditional monitors are in the 23 to 27-inch size range.

As you scale the size up to the 80+ inch range – as do these TVs, then the additional “4K” resolution (3840×2160) does offer visible benefits to image quality.    Essentially, 4x traditional HD images (1920×1080) can be displayed side by side on a 4K TV.

There are larger TVs, such as the Worlds Largest LED TV announced earlier this year, but without this 4K resolution, they are more suited to be viewed from afar (like traditional conference room / projector environments).   These 4K TVs can be viewed up close while maintaining visual details, which makes them suitable for detailed visual collaboration work.

Passive vs Active 3D on 4K TV

3D is where 4K can really excel.   There are two primary methods used in 3D content display:

  • Active 3D:  Uses expensive, battery-operated shutter glasses that rapidly shutter open and closed.     Information meant for your left eye is blocked from your right eye by a closed shutter.
  • Passive 3D: Uses inexpensive polarized glasses, like most movie theaters.  The TV has a special filter that polarizes each line of pixels. This filter makes the odd lines on the screen only visible to the left eye, and the even lines only visible to the right.

The downside to Active 3D (besides the expensive glasses) is that half of the time the light is blocked from your eye – so the image is noticeably dimmer than non-3D content.     If brightness is not your primary concern, then astounding 3D resolution can be achieved.

The downside to Passive 3D is that half the horizontal resolution is blocked from your eye – so the image is noticeably lower resolution.   However, on a 4K TV, this means that even a 3D image is HD quality (1080p) – and brighter than on an Active 3D display.

At the moment, Sony appears to be leading the charge in 4K UHD – their 84-inch 4K TV is already available. LG and Toshiba have also announced that they have 84-inch 4K TVs “coming soon”, and other manufacturers will soon follow.

Sony also partnered with SES, who operates a fleet of satellites, to demonstrate their new 4K transmission equipment that compresses 4K data down to a size that can be handled by existing HD transmission equipment. Sony is clearly trying to get 4K technology accepted by the industry.

Features at a glance:

  • 84″ (diagonal) screen size
  • 4K (3840×2160) resolution
  • Up scaling to 4K
  • Full HD Passive 3D capable
  • Built-in WiFi, and streaming apps.
  • Media Remote app to control TV with a smartphone
  • DLNA support (stream content from DLNA server on network)
  • 50-watts of audio output – with Surround 3D
