As mentioned in earlier news we are introducing multi-touch video-walls – this is now on show in our Silicon Valley showroom in Morgan Hill.
The displays are protected with bonded AR coated glass using high temperature silicon. The touch wall size can be up to 7ft high and any width and is resistant to ambient light interference.
Visitors are welcome – 18440 Technology Drive, Morgan Hill, California 95128. Tel: 408-782 7773
The following is a quick summary comparison of the two product families, SVX and ALR showing some of the main differences:
|| SVX family
|| ALR family
||Up to 10 bit
||Up to 8 bit
|RS-232 / Ethernet command set
|Display resolution support
||Up to 4k
||Up to 1920×1200
|Input signal frequency
||Up to 75Hz
A few notes:
- Memory buffer: This allows for more signal processing so the controller can accept a wider range of frame rates and interlaced signals. It also enables functions such as Picture-in-Picture (PiP), image zoom, variable aspect scaling, screen markers.
- SVX-2560 will support the image flip function.
- * Ethernet support: The ALR family of boards do not have integrated Ethernet support but will work with the IP-60 add-on board for Ethernet command support via RS-232.
- ** In most cases the input frequency is limited to 50/60Hz.

The IP-60 Ethernet to RS-232 add-on board for Digital View controllers is due to be fully released within the next week. This board enables a display system developer to add Ethernet connection to make use of the extensive RS-232 command set. As with the IP-50 the IP-60 operates in two modes:
- Web server mode: Create a web-page stored on the IP-60 and then accessed using a web-browser.
- Direct command mode: Use a PC, control device like a Crestron, AMX, Bitwise type controller or a custom device.
As noted in an earlier blog, the IP-60 is integrated into the upcoming SVX-2560. The IP-60 will be updated in coming months with added support for sensors and other display related accessories such as cooling fans.

The full RS-232 command set for the SVX family of controllers (SVX-1920, SVX-1920-SDI, SGX-1920, SGX-1920L) has now been posted to the Digital View website for download, see www.digitalview.com/software-services. At this stage it is an initial draft, the commands are all there but future versions of the document will improve formatting and provide additional information.
The commands cover functions for:
- OSD buttons
- General settings
- On-Screen-Display (OSD) related
- Input signal selection
- Input signal data
- Hardware settings & Data
- Picture in Picture (PiP) functions
- Image Zoom & Position
- Color Temperature functions
- Gamma correction functions
- Backlight functions
- On-screen markers
- DisplayMark integration functions
- Ethernet input settings
- Text overlay
These are ideal for creating your own RS-232 application; Programming a device like Crestron, AMX, Bitwise type AV control systems; Creating your own device such as a button board to directly access specific functions.
In a subsequent post we will also be providing the RS-232 commands for the ALR family of controllers as well as the manual for sending commands over Ethernet (the command set is the same). One thing to note is that if the functions are the same we keep the commands common across all models subject to any specific limitations.
As the first of a number of software utilities for use with Digital View LCD controllers and displays using them the Controller Utility for the SVX / SGX controller family has been posted to the Digital View website for download. This Windows based app connects to a controller using RS-232 serial communications and provides functions to:
- Adjust and set colors
- Rename the input ports

Here is a preview of a new video we prepared for our video-wall displays…
Further to the earlier post about bonded glass video-wall displays for touch integration the news is that our touch options will extend from standard single display options, through 2×2 video-walls and beyond.
The size limit for the touch enabled video-wall is looking like it will be over 2 meters in height with no limits on width!
And with multi-touch.
More details shortly…
Digital View LCD controllers have incorporated Ethernet connectivity for quite a few years now as an alternative to the RS-232 serial interface that is also provided on all its LCD controller models. The Ethernet interface has also been available as a separate module known as the IP-50.
Over the past nine months we have introduced the IP-60, a more powerful version of the Ethernet module. The improvements are most easily described as a faster processor, more memory and more I/O functionality. So for example in the web server mode, larger and more complex web pages can be written as a user interface. In general the performance is faster. We are progressively enabling more device interface capabilities, for example to various sensors (light, heat etc) and devices such as fans.
To help with the usability of this Ethernet connectivity we will be providing various applications designed to run on Windows and communicate through TCP as well as UDP in another update. As with the IP-50 and RS-232 serial connection, the full command set of the controller are available.
The IP-60 is incorporated in the upcoming SVX-2560 controller as mentioned in an earlier post and will also feature in our soon to be announced 4K controller.
With limited samples due for mid Q2, 2014 here is a photo of the upcoming SVX-2560. This board will offer panel and input support for up to 2560×1600 (60Hz) and 1920×1080 (120Hz) with dual digital inputs, image flip (H&V) as well as all the functions of the SVX-1920. The SVX-1920 also features the new more powerful IP-60 Ethernet interface enabling both a web-server as well as TCP comm with UPD planned.
In coverage of a recent SID (Society of Information Display) conference the case was put forward that quantum dot technology will make OLED irrelevant within 5 years. The point being put forward is that while quantum dot backed LCDs already provide a color gamut that surpasses OLED a future technology referred to as QLED using quantum dot LEDs will replace OLED.
As reported in an earlier blog the market for displays is looking exciting with plenty of technical innovation and invention yet to happen, it is good to see another perspective added to the potential evolution of displays.
Speaking of SID, Digital View will again be exhibiting at Display Week which we are happy to see is back to being held in San Diego this year, the dates for the exhibition are June 3-5. This will probably be our 17th or 18th year exhibiting there.
Over the last couple of years we have been consolidating our products into two distinct families:
- SVX-xxxx: This the most feature rich family and includes models such as the SVX-1920, SGX-1920/L, SVX-1920-SDI as well as harsh environment versions.
- ALR-xxxx: Providing compact and cost effective solutions the ALR family includes the ALR-1400, ALR-1920, ALR-1920-SDI, ALR-1920-120 and the DD-1920-Dual-DVI.
Each of these models provides clearly differentiated functionality such as support for 120Hz panels or HD-SDI inputs. In addition we of course still support a number of legacy models.
SVX-2560: Looking forward at the rest of 2014 we will continue this with the introduction of the SVX-2560 providing support for panels up to 2560×1600 as well as some 120Hz support at 1920×1080 making a versatile platform for display system developers. This is approaching launch status and is planned for Q2, 2014.
SVX-3840: After that will be the SVX-3840, our first 4K controller with similar functionality to the SVX-2560. More details later but we will be showcasing this very soon!
Later this month, March 2014, we will be introducing an update to the ALR-1920-SDI controller providing a number of excellent enhancements:
- PWM backlight brightness adjustment support, controllable through OSD menu and RS-232 commands.
- Repeat function on OSD menu button (up/down key & left/right key) control, e.g. press and hold to auto forwards/backwards.
- Custom panel timing programming (e.g. *.inf) through programming tool, G-Probe.
- SmartISP programming for firmware upgrade through HDMI/DisplayPort.
- DDC/CI commands, e.g. brightness, contrast, RGB gain, power states (e.g. On, Standby, Sleep mode).
- Software controlled power on/off through RS-232 command “0xc8”.
- Improved EMI performance.
- Improved HDMI sync detection.
- Modified image defaults and various other updates.
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.
