Another accessory for display systems to complement the Digital View family of LED (LCD) panel solutions, the Green Power board – this little board, pictured below, can be used with any Digital View controller (or display driver if you prefer) to power down the system with less than 0.1W power consumption when in standby mode.

The ‘Green Power’ board uses RS-232 to trigger a power Off or On command, the display system will then shut-down just leaving the Green Power board awake but only drawing less than 0.1W. The board can also be daisy chained so a series of displays can be deactivated or activated simultaneously.

This mini joystick can be used to control the OSD or to invoke preset functions with any Digital View LCD controller / driver board – it can even be used to replace the normal OSD button board. The joystick incorporates an RS-232 interface that can be factory custom programmed to set the functions of the joystick to any of the very extensive Digital View RS-232 command set.

With a lifetime of over 100,000 cycles the joystick is suitable for industrial applications. The joystick operates in 5 directions, up/down, left/right & push.

We have been testing Samsung’s 21.6” square LED (LCD) panel with our controllers – this seems to be an excellent display for interior designers to build concepts around. The super narrow bezels mean that the displays can be assembled into walls.

The ICDM (International Committee for Display Metrology) and SID (Society for Information Display) have published a very comprehensive set of standards for measuring display characteristics. 

It is very impressive and available for free download at, well worth a look for anyone who wants to know more about display specifications and their measurement.

Viewrinal, an idea that keeps going…

Back in 2001 Captive View (a Digital View joint venture) launched a washroom media product called the Viewrinal, an LCD display built into a urinal. The Viewrinal was successfully installed in a number of venues, most notably a few nightclubs in London, UK, and also caught some good media attention. Captive View was sold during 2003 and since then the concept has resurfaced many times with other companies – most recently with Sega and their Toylets, see

Color & LCD Panels

April 19th, 2012 No comments

Color is an involved topic but in the context of LCD panel selection there are generally two main parameters specified:

  • Color depth: This represents how many colors a panel is technical capable of showing within its color gamut. LCD panels mostly comprise 3 colors R (red), G (green), B (blue) so the number of shades possible for each color indicates the theoretical number of colors. See table.
  • Color gamut: This refers to the range of colors a panel is able to show out of the visible spectrum, it is typically represented on a 3 coordinate color map. Typical color-space references are NTSC, Rec. 601 and Rec.709, the color gamut will be the extent (as a %) to which a panel is able to achieve the color-space reference.
For most industrial applications the color depth is unlikely to be particularly important. For applications where video or images are shown, particularly of things like the sky or skin, a greater color depth should enable a smoother looking image without noticeable steps between color shades. This of course depends on other parts of the display system being up to the same standard.
Color gamut will be considered further in a later blog.

LCD Controller Recommendations – Digital Signage

April 3rd, 2012 No comments

If you are planning a digital signage display system the following LCD controllers are a great place to begin:

  • SVX-1920, the most popular choice as it offers a significant number of functions and control options together with support for DisplayMark display and system monitoring as well as support for 120Hz panels when used with the IE-1000 add-on board.
  • ALR-1920, when straightforward full-screen video is required and cost is a key factor the ALR-1920 is a great choice. It is compact and easy to work with and gives excellent results.
  • SGX-1920, this is the very top of the range providing all the features of the SVA-1920 plus a considerable number of input signal options as well dual digital input and powerful Picture in Picture capabilities.

For details of all Digital View controllers see, this also provides details of complementary accessories.

Various display resolutions have been given names, the list below shows what I feel are the most common names with the respective resolutions – there are are plenty more but they are not in common usage:

  • QVGA: 320 x 240
  • VGA: 640 x 480 (VGA is also used a generic name for the ARGB input)
  • SVGA: 800 x 600
  • XGA: 1024 x 768
  • WXGA: 1280 x 768
  • SXGA: 1280 x 1024
  • UXGA: 1600 x 1200
  • WUXGA: 1920 x 1200
  • WQXGA: 2560 x 1600

Personally I prefer to stick with the actual resolution, it is less ambiguous.

Autobrite sensorThe ‘Autobright+’ sensor board (pictured) changes LCD contrast and black-level to preset levels according to ambient light conditions. It also recognizes RS-232 commands for remote control of these settings. This kind of setting adjustment is useful for low light conditions.

It is an example of one of the many add-ons and product extensions that add value to a display system.
