Flat panel displays
This category includes plasma, LCD, and LED, and the right option for you will depend on required size and application. Given the relative newness of flat panels, to date the larger mediums are still more costly than traditional projection systems. However, benefits include vastly improved image quality, resolution and brightness. In addition, whilst the initial outlay is greater, running and maintenance costs are significantly less in the long term. With new technologies being more focused towards energy efficiency, the LED panels are also a better choice environmentally.
Touch screen overlays are available for various mediums, allowing users to interact using the interlay between computer programs and the panel for presentations.
