General Description:

Video display systems are made up of multiple LED panels that can be combined to produce larger display systems. These systems are capable of displaying both dynamic and static video content. Uses include displaying video, static images for building directories, tickers for displaying current information, and advertising.



Attributes of Video Display Systems:

Pixel Pitch affects the resolution of the video. You can choose pixel pitch based the viewing distance of your audience. For example, if your audience will be around 12’ (4m) of the screen, you should choose a smaller pixel pitch around 4mm. If your screen will be hanging from overhead, a pixel pitch of 6mm may be more appropriate.

Viewing Angle will determine the max angle at which your audience will be able to see the content of the screen. If the audience will be viewing content head-on, a smaller viewing angle might be acceptable. However, if the screen will be hung from the ceiling, it may be appropriate to seek a larger vertical viewing angle.

Interface Units must be used between the content player and the LED panels. Some interface units are designed to rotate, scale, and otherwise adjust video content, while others require content to be pre-edited.

Source Compatibility affects the type of media you can hook up to the screens. Depending on your media source (CPU, laptop, USB, SD, etc.), your Interface Unit will need to have the correct ports to accept the connection. From the Interface Unit, the screens are linked together using CAT5 cables.

Power is normally supplied by a standard 120 VAC / 240 VAC wall outlets.



How to Specify:

Editing of Section 101500 is designed to start with the optional checklist at the top of the section. When choices are made using the checklist links will turn on the corresponding information in PART 2. Finish making product decisions in PART 2.  

The various configurations of video display systems specified comprise the main articles in PART 2. When a particular video display system is activated for use in the project, related articles and optional text in PARTS 1, 2, and 3 will be activated as well.

Progress to PART 3, and finish up with PART 1. Review what has been activated by SpecLink’s intelligent linking to be sure all your requirements have been covered. Turn on additional paragraphs, or add “user” paragraphs as necessary.

When a particular article or paragraph is chosen that contains a reference standard in PART 2 and PART 3 the corresponding standard cited under REFERENCE STANDARDS in PART 1 is activated. If the Consolidated List of Citations option is active, cross sectional links (not visible in the links window) will activate the reference standard in Section 014219 – Reference Standards as well.

When a particular article or paragraph is chosen that cites another section in PART 2 and PART 3, the corresponding Section cited under PART 1-RELATED REQUIREMENTS is activated.

Certain Sections cited under PART 1-Related Sections are not cited in either PART 2 or PART 3 but are listed under RELATED REQUIREMENTS because they include items that might be expected to be found within this Section or include action items important for the completion of the work that are not specified in an obvious location (e.g. isn't obvious from the section title).

All optional text and choices under PART 2 include a fill-in to accommodate any updates that listed manufacturers may offer but are not shown in the choice options. Default options for choices are based upon what would be reasonable for the application. The content of PART 2, including the choices, has been structured to accommodate the listed manufacturers.
