I did an initial post on the topic of latency back in June, shown below is a more complete list of latency measurements for various Digital View LCD controllers. For many applications the latency caused by buffering and image processing in the controller is not an issue, however with the increase in interactive display systems in digital signage and corporate AV it is getting more attention. We recently ran tests using a third party input signal to image latency tester designed to provide a consistent methodology and basis for comparison.

LCD Controller model Latency (ms)
SVX-4096 (60Hz LCD panel) 15ms
SVX-4096 (120Hz LCD panel) 23ms
SVX-2560 35ms
SVX-1920v3 44ms
ALR-1920 / DD-1920 11ms
ALR-1400 / HE-1400 13ms

The timing is measured on a consistent basis using an input signal timed to the middle rows of the display.

LCD Controller Commands Page – Preview

July 11th, 2016 No comments

We have created a new webpage related to the very extensive LCD controller command set available for Digital View controllers, you can see a preview of the webpage here:

There are many reasons users of finished monitors and displays might use commands, for example…

  • Room controllers: To work with room controllers such as from Crestron, Extron, AMX and others. These can be readily programmed to control Digital View LCD controller enabled displays, typically this will be for on/off and brightness but may extend to other functions in more complex installations.
  • Hotkey functions, for example some users have display systems with multiple video sources and want to switch between them easily, integrators make small button boards that send a command string to trigger switching inputs. Other companies want to invoke certain settings, sometimes multiple settings such as changing the color and brightness setting with a single button push.
  • Computer application control: Customers can develop their own applications or integrate control into applications for management of display functions. One interesting example is to provide on-screen display controls to be used with touch screen monitors. A readily accessible example of how to do this is with the Digital View Controller Utility, a free Windows compatible application giving access to the commands supported by a particular LCD controller model.
  • Media player control & data: Especially in digital signage applications being able to control and monitor the display is becoming increasing important. The Digital View provides both as some commands make changes while others are for polling the system and retrieving data.

Latency – Controller Test Results

June 18th, 2016 Comments off

The topic of signal latency from input to image has arisen in various LCD controller and display projects over the years, for many applications the latency caused by buffering and image processing in the controller is not an issue, however with the increase in interactive applications in digital signage and corporate AV it is getting new attention. We recently ran tests using a third party input signal to image latency tester designed to provide a consistent methodology and basis for comparison.

Here are some of the fastest results we achieved with our controllers:

  • Driving a 3840×2160 panel: 15ms
  • Driving a 1920x-1080 panel: 11ms

These are very fast times and to put this is some context we found that some controllers gave results as much as six times slower, ie over 100ms. As mentioned depending on the application it may be that image processing and functions are more important than low latency but if latency is an issue it is worth discussing the controller options with us.

LCD Controllers & Decision Support

May 30th, 2016 No comments

I was reading John Maeda’s book, Simplicity, recently and it made me think about our range of LCD controllers and decision support for users. We have quite a few models so which to choose? There appear to be two main issues, understanding what is available and being able to make an informed choice.

To make selection somewhat easier we could reduce our product range, it would certainly be welcomed by our logistics and supply chain team, but it would limit our ability to meet the needs of niche customers.

So the alternative is how to make the product range easier to understand. One very simple approach is grouping. To some extent we did this when we created the SVX, ALR, DD and HE families. That is three general families plus the HE family stands alone as designed for harsher environments.

These can be briefly explained as:

  • SVX: The top of the range models. Fully buffered, multiple inputs, available up to True 4K input, full command set, Ethernet port for commands.
  • ALR: Line buffered, multiple inputs, available up to Full-HD 1920×1200 panel support, reduced command set.
  • DD: Single input but with many models & inputs to choose, otherwise similar to the ALR range.
  • HE: Made up of a selection of models from the SVX, ALR and DD models that have been modified to suit harsher environments.

But does this grouping make choosing a model easier?

Alternatively is possible to go through a selection of ‘must haves’, for example panel resolution. However most panels are now 1920×1080 and most of our controllers support that so it probably doesn’t do a lot to whittle down the controller choices.

Another is signal inputs, however many of our controllers support multiple inputs and even though only one signal type may be required giving up the flexibility of other inputs is a tough choice as once made is hard to go back on.

Of course price may be an issue and it is generally a matter of deciding over features which is why it is important to review the ‘must have’ functionality.

My recommendation is to use a process of elimination to begin with, strike out the models that absolutely do not meet requirements, for example:

  • Start with panel resolution, it is not a big step but it helps.
  • Then input signals, decide on ‘must have’ input signals and focus on those models.
  • Determine your environment in particular from a temperature and vibration point of view.
  • At this stage you may still be left with a few models so it is probably worth a more in depth consideration of the features of the remaining models and a discussion with us or our resellers.

Attracting many references to movies and science fiction, transparent OLED displays are here and being used in retail and trade shows. They are certainly eye catching as the contrast and transparency exceeds anything that has been available previously. Looking at the image on the right below you can see the transparency is in the dark parts of the image.

So far both the ALR-1920 and SVX-1920v3 controllers from Digital View have been setup to drive the 55″ model (ASI545FB01-0) and have been deployed in displays used at CES 2016, Infocomm Connections as well at the Superbowl in San Jose.

We also recently set one up with a touch screen which started the movie references all over again.
