Follow this step-by-step guide to find a screen suited to your control room. For further information and guidance, please contact your local dnp partner.
Screen size is normally the first thing to be determined when designing a control room. Optimal screen size is conditioned by two factors: the amount and form of information to be displayed; and the operators’ viewing positions.
The crucial thing is that all information displayed should be easy for the human eye to view, read and understand. Use the following guidelines to help you arrive at the appropriate screen size for your instillation:
The optimal screen size and viewing distance also depend on projector resolution.
All dnp screens have a native resolution that is far higher than even the highest resolution standard projectors can currently deliver. This ensures that every single individual pixel projected re-appears in crystalline clarity on the screen itself.
Because control room operators spend many hours in front of the display, it is extremely important that the display is designed in an eye-gonomical way.
This means that the display (the combination of projector and screen) must provide an image which is in balance with the levels of ambient light in the room. If screen contrast is too low in a bright room, the image will look weak and washed-out making it next to impossible to read. On the other hand, a very bright display in a darkened room will often result in viewer eyestrain and headaches.
dnp’s product range includes a wide selection of high-contrast screens optimized for the light conditions in different types of control rooms.
Your local dnp partner can provide you with further information and assistance in measuring room brightness levels and finding the right screen to cope with them.
Should it be an easy-to-install Supernova front projection screen or a built-in rear projection solution? Basically this depends on two things: the level of ambient light in the room, and how much space is available.
If the room is brightly lit, only optical rear projection screens can provide sufficient contrast levels to secure a good all-day viewing experience. However, if room lighting can be controlled and there is no direct light onto the screen from windows, optical front projection is also an option.
A rear projection installation requires space for rigs, mirrors and projector behind the screen. In most cases the screens will be build into an artificial wall that conceils the projection equipment. As a guideline, the build in depth will be 60-100% of the width of individual screens in the display wall (depending on number of mirrors and projector lens throw). If the room layout doesnt allow this, choose front projection.
