Here is a new gadget we made for a development project but clearly has potential with other projects. It is a USB emulator board supporting up to ten buttons. The USB emulator board can be programmed to send specified commands over USB based on button presses.
This capability may be most relevant in situations where a PC is normally required to send commands over USB to control a device. Instead the Emulator board can replace the PC which is how we are using it in the project is was designed for. That can be a very considerable cost saving in a system design.

Video-walls with touch interactivity is on its way. As a first step in this process now supplies its 46″, 47″ and 55″ ultra-narrow bezel video-wall display modules with the all important protective glass front. The 3mm soda lime glass with AR (anti-reflective) coating is bonded using a temperature cured silicon with a refractive index to match the display to ensure the best visual results.
Optical bonding optimizes the visual clarity of the displays as it eliminates any internal air-gap that would lead to internal reflections then the AR coating further reduces reflections on the front of the display. The operational temperature range of the silicon bonding material is -50C to +150C, furthermore the bonding is repairable.
Video-walls continue to increase in popularity especially with the growth in public digital signage and this has also attracted demand for interactivity using large format touch solutions. These high reliability displays are designed and assembled in the Digital View NRTL approved facility, south Silicon Valley.
In early April 2014 we will be announcing our video-wall touch options.

Over the past few years it has been encouraging to watch LCD panel sizes increase and prices drop to mainstream affordability but having been around CES 2014 the outlook appears positively exciting.
From an industry point of view it is not just the improvements that users can see but also the advances in the technology that enables them. My expectation is that developments will impact cost and functionality as much as image, if not more.
Over the next few years I foresee that certain issues will become non-issues from a customer perspective. Viewing angle is close to being a non-issue while response time, refresh rate, color, contrast and resolution are all rapidly heading in the same direction. And the innovations or inventions to deliver this will result in cost reductions.
Curved screens look cool so will appeal to some but I expect it is the ability to make a curved screen that is most important because of what it indicates about the advances in production technology. It wouldn’t surprise me if the ability to make a curved screen also enables a flat screen to be manufactured for lower cost or to consume lower power, or for screens to made in ever larger sizes or with narrower bezels.
Same with color, some of the technologies to enable perceived color improvements may also enable other benefits that will lower cost.
In the past it may have seemed counter intuitive to consider that a development that delivers significant feature improvements will also result in reduced costs but now it is pretty much expected.
We can look forward to being able to source displays providing the specifications we need, no matter the shape, size, resolution or other characteristic.
The Digital View ALR-1920 family of LCD controllers support a subset of DDC/Ci commands to enable a computer to send commands to the monitor through the video port (VGA, DVI, HDMI). The specific Digital View controllers supporting DDC/Ci include:
- ALR-1920 : A low latency controller supporting panels & signals up to 1920×1200 resolution.
- ALR-1920-SDI : Adds SDI connection up to 3G-SDI.
- ALR-1920-120 : Adds 120Hz panel support.
- DD-1920: Designed for higher volume display applications.
Functions supported include:
- RGB color
- Input source
- Power states:
- On = Always on, displays “No sync” if no input signal.
- Standby = Power off to the panel and backlight.
- Sleep = “No sync” message displayed for 10 seconds then backlight off.
If you have any questions regarding this function or any of our controllers please contact us.
A quick note, content is generally created to the following color standards so the closer a display comes to being able to match these standards the more accurate the display result:
- Color temperature: 6500K
- Gamma: 2.2
- Color gamut: Rec.709
There will however be many other factors that impact how people might judge a video display system, for example resolution, viewing angle, brightness, contrast, response time, refresh rate, latency. Ultimately it will be the needs of the application that will determine which of these are most important, for example a broadcast display will require excellent color fidelity while an outdoor display will need high brightness and contrast.
We have had an interest in digital art for some time but recently taken this a step further with the setup of our showroom in Morgan Hill, California, showcasing both video art and digital display systems for presenting it (here is a video https://vimeo.com/…). Over the next couple of months we will also be sponsoring exhibits in various venues in the Bay Area.
The question is how are people going to monetize digital art. It is a question that has been considered in a couple of publications recently, name Wired (http://www.wired.com/…) and The Verge (http://www.theverge.com/…).
So what is the best way for an artist to sell digital art, or for a customer to buy it:
- With a display?
- On a USB drive?
- As an algorithm?
- As a hosted web domain?
- With a media-player?
Probably all of the above and no doubt people will think of many more business models. Certainly in the past we have sold displays to digital video artists who have then sold the entire system, we have also created a custom media-player locking solution so a video file will only play on the matched media-player which can be used with any display.
Designed for higher volume applications requiring a minimal feature set the DD-1920 LCD controller is a very compact cost effective display interface solution. Suitable for LCD displays up to 1920×1200 resolution the DD-1920 is currently available in three versions:
- DD-1920: This is the base version with HDMI signal compatible headers for video input.
- DD-1920-HDMI: This has a standard HDMI connector for video input.
- DD-1920-Dual-DVI: This model has two DVI inputs, OSD or RS-232 selectable. This model is pictured below and can be seen on our website here.
Under consideration is a VGA input version – let us know if this is of interest. As with most of our LCD controller the DD-1920 family are all multi-panel compatible and have RS-232 for command and controls.
Note these models are subject to an MOQ for purchases, please contact your local Digital View office or distributor for details.
In talking with one of our business partners this morning I was reminded of the issue of video signal latency and our solutions for the problem. Video latency is where there is a delay between the source of a video or image and the image on the display. Some of the ways this issue can be seen as a problem include:
- Lip sync, in this case you hear the audio before the person appears to say the words. This can affect video-conferencing systems as well as other digital media transmission systems.
- ‘Cursor delay’, you move the cursor or click a button and the image lags behind the action. This is likely to be an issue when the system is operating over a digital distribution system.
The solution: Amongst our extensive range of LCD controllers (the electronics that puts the image on a flat panel display in a monitor) we have various models that are low latency, of these the most popular is currently the ALR-1920 that offers HDMI and DisplayPort digital inputs.
Recently we have been testing the tintup.com social media feed system with our square displays to show Instagram photos. The system work really well and is a great way to create a feed for images and show them in their correct aspect ratio.
Here are a few photos:

To make the relocation of video-wall modules, for example when exhibiting at trade shows and other events, we have designed and made video wall module cases as shown.
On 17 September 2013 our US office was honored to have the local Chamber of Commerce attend for a ribbon cutting ceremony.
The IR-LED board (p/n 416302000-3) is one of those small accessories that sometimes gets overlooked but plays a valuable role. Designed to be integrated on the inside of an enclosure with suitable access holes. The IR receiver is used for accessing the On Screen Display (OSD) menu of Digital View LCD controllers and works with the Digital View remote control.
The connection cable (p/n 426302000-3) is available separately or both as a kit.
The cube is a 3D arrangement of 23″ LCD panels around a rigid aluminum chassis – each panel uses a low latency Digital View LCD controller. That is the technical explanation.
From a visual perspective the result was more impressive than we imagined. We made the Cube to be one of our exhibits showing how LCD displays can be used as an artists medium and over the coming weeks we will be experimenting both with content and also graphic processors.
Here is a brief video about the making of the Cube:
