Modern videowall systems have made significant improvements over previous generations. The new systems have everything it takes to make control rooms and operations centers more efficient and functional. You can choose from three videowall technologies. They are DLP, DLP will LED illumination, and LCD. However, it’s important to match the appropriate technology to your application. The evaluation process takes a little time and requires a specialist to guide you; however the results are worth the investment.
Integrated videowall systems are comprised of three components. Like the computer at your desk, these components include display (regardless of type), videowall processor (also called a controller) and keyboard with mouse. Video wall systems can be self-contained and free-standing, or wall mounted with components separately placed.
Control rooms, like other mission-critical operations, have special needs and the videowall you choose should fit the operational and physical requirements for the room. Here is an overview of the display types.
Digital light processing (DLP): These videowall systems feature interlocking rear projection cubes with a video processor LED Video Walls. These are sometimes referred to as a projector in a box. The size of a DLP screen size is proportional to its depth. However, it has a relatively small footprint making it suitable for smaller control rooms and operations centers. DLP technology relies on the use of lamps that need to be replaced periodically. The life expectancy for DLP lamps is around 9,000 hours and do not require a specialist to replace them. Rear projection cubes can be either installed into the wall, or a custom cabinet that rests on the floor.
Digital light processing with LED illumination: This technology is similar to DLP lamp except for the light source which is LED (light emitting diodes). These videowall systems are also comprised of interlocking rear projection cubes and video processor. The LED light source doesn’t need to be replaced as often and has an estimated 60,000 hours life expectancy. DLP LED cubes are more expensive initially as compared with DLP lamp, however, they need very little maintenance and attention. They too can be installed into the wall, or free-standing cabinet.
Liquid crystal display (LCD): An LCD videowall consists of flat LCD panels aligned to form a matrix, or one palette. The LED backlighting makes the displays lighter with thinner bezels. An LCD videowall can be mounted directly on the wall, or can be installed in a free-standing, modular cabinet. These commercial grade LCD panels have a small footprint and have become increasingly affordable. However, they do need to be replaced eventually unlike DLP cubes that have an infinite life expectancy if maintained properly.
Regardless of the video wall display system that you choose, high performance, reliability, and cost-effectiveness are attributes to consider. Enlisting the services of a professional consultant will ensure that you are able to make an informed decision and wise investment.
