Screen Display
Screen display technology is used in control rooms to allow managers to:
Provide a system overview of a complex, changing environment - Monitor critical and high value assets
- Interpret, analyse and visualise a complex set of information
- Present and communicate status and direction
The screen display serves as a tool to help make complex decisions.
A videowall is a control system and an array of video screens that allows for the display of one or many information sources. Screen display devices can be video monitors, projectors or panels.
- A videowall system provides flexibility for viewing many images on multiple screens or fewer large images enlarged providing greater detail to a larger audience
- High brightness is maintained in the display regardless of the image size
- High resolution display capacity is created with multiple display devices maintaining image quality regardless of display size
- Total system reliability is increased with the redundancy of multiple display devices
- Videowall equipment allows lower cost components to be repaired or replaced quickly

Information Sources displayed in control rooms may originate from a variety of sources including:
- Analog or Digital Video sources from surveillance and replay devices
- Analog or Digital RGB information from computer devices
- Networked information from desktop or application servers
Connecting these sources to the display system may require a variety of interfacing, cabling, switching and control solutions. Screen display systems are capable of accepting information from all of these sources in a manner which preserves the original quality.
Image Processors provide a critical function to a videowall. They combine the visual information from different information sources for presentation in a variety of configurations on a display system.
Important considerations when selecting image processors for your display system include:
- Legacy Information Sources: What are your current information sources and how will you integrate them with the new environment solution?
- Source Flexibility: How many sources and what type of sources are required for your system? How many will you need to display simultaneously? Will new sources need to be integrated into the system in the future?
- Image Quality: What image quality do you require for video, RGB and network sources?
- Presentation Intensity: Does the display need to present static content from information sources that rarely changes or does the solution require that users be able to quickly change the information and the manner in which it is presented?
- System Performance: With what speed do you expect images to be displayed when they are created or repositioned on the display?
Screen Display Systems : Selection criteria for display systems can vary greatly depending upon the physical environment, lighting conditions, viewing positions and budget. Most frequently, digital projection cubes provide the most practical solution for command and control or simulation videowalls.
Control Interfaces : The presentation intensity requirements, network operating system, security policies and interaction with the user environment and business process can shape the requirements for the operator interface.
