While people struggle with signal quality over extended cable lengths and talk in terms of meters (or yards) fiber makes video cabling over a kilometer easy and reliable. Digital View offers the SVX-1920-SDI interface controller for display system developers as well as the point to point fiber connection boards. We will be talking more about fiber in the coming months.
Flat panel displays such as LCD (or LED as they are incorrectly called in consumer products) are exciting, they have enabled a revolution after revolution in all manner of devices, but they are also exciting as a medium for art and self expression.
We put together a sizable showroom in our Morgan Hill facility where we design and assemble all our large screen display products as a venue for people to see some of what is possible. Our goal is to provide inspiration for video artists, display system users and developers alike.
On show in September we have convex curved video displays, these look great with wide angle video footage such as may be taken with a GoPro Hero3, there are video-walls using near seamless ultra-narrow bezel displays, an LCD table which features the mesmerizing and omni-directional video art of Anne Spalter and more.
Over the coming months we will be featuring even more so please come back for updates.
We made a short time-lapse video documenting the making of the obsidian rock display for our Digital Display Showroom in Silicon Valley, California.
The showroom features video-walls, video-squares, video-table, curved video-displays and custom video displays for corporate and digital signage video applications.
The Digital View display builder product guide which includes the LCD controller products and accessories is now available in English, German and French. A Spanish version is scheduled for release in the near future.
The download links are on the main Digital View display builder web page at http://www.digitalview.com/display-builder-home.
A quick look at a few LED type LCD panel sizes, resolution and ppi (Pixels Per Inch:
- 27” 2560 x 1440: The ppi is 109 pixels per inch.
- 24” 1920 x 1200: The ppi is 94 pixels per inch.
- 15.6” 1920 x 1080: The ppi is 141 pixels per inch.
To put this in some context:
- Laser print quality 20 years ago was 300dpi and models with this resolution are still available, for some time now 600dpi has been normal and 1200dpi is readily available. Even 2400 dpi is available but expensive.
- Inkjet printers typically offer 1200dpi or higher, up to around 4800 dpi.
- Amazon Kindle Paperwhite is 212 ppi.
- Apple iPad Retina is 264 ppi (older iPad 2 is 132 ppi).
- Apple iPad Mini is 163 ppi.
- Apple iPhone 4 & 5 is 326 ppi.
- HTC One is 468 ppi.
- Per Ray Soneira, human vision is at best capable of resolving 600 ppi from 10 inches.
Digital View will be exhibiting for the 16th year at SID’s Display Week being held in Vancouver May 21-23. Many companies show their latest display related technologies at Display Week and for Digital View this will include some new controllers for HD-SDI and video-walls.
Update: Here is the booth photo…
The free Controller Utility application allows users to remotely access, monitor and control display systems using Digital View controllers over RS-232.
It is a full version with all functions enabled letting users explore the opportunities for system solutions. Digital View also offer engineering services to modify the user interface for custom user interface, logo etc.
Contact us for the latest version and further information.
The more recent Digital View controller models also support Ethernet communications for similar functionality. Although the Controller Utility does not support Ethernet access it provides a great test method for considering development options.
Product samples and full details on the Digital View website are expected in time for SID which is being held in Vancouver this year, 21-23 May.
An interesting use for transparent LCDs was demonstrated by Jinha Lee (MIT Media Lab) who developed the idea in collaboration with Daewung Kim. The video really explains itself:
As Lee explains in a Fast Company article (here) with just a camera you can’t rotate your arm as the watch will not follow you.
Using the Controller Utility on a PC connected to the SVX-1920 or HX-1920 via RS-232 ports can be renamed within the OSD as seen by users of the display system.
The Digital View Accessories
webpage has been updated with a number of new items such as Autobrite+ and others that are coming soon.
These accessories include add-on boards enabling an even more enhanced feature set for display systems. An example is the HD-SDI add-on boards that provide up to 3G-SDI input for compatible controller (LCD driver) models. The upcoming HD-3000SF model adds fiber connection for long distance signal cabling.
Another board soon to be upgraded is the IP-50, this enables Ethernet network connection for command and control of the display system. The upcoming IP-60 will be faster and add more memory for user interface pages.
To meet the connection requirements of very thin displays Digital View uses a flexible PCB to go from the flat flexible cable (FFC) with board to wire connector type to its standard panel cables. These are made to order to suit the specifications of the LCD or OLED panel.
Digital View is at Electronica 2012 in Munich – the exhibition runs from 13 to 16 November. On show will be our latest LCD/LED panel interface controllers, an extensive selection of display system accessories and a video-wall system solution.
All Digital View LCD controllers (LED display drivers) come with an RS-232 port providing full access to the very extensive functions available.
This capability can be used in display systems requiring control from Crestron, AMX and similar media installation control systems.
