Development of P4140 video data wall projector

摘要

The P4140 is a 3 cathode-ray tube (C RT) video data wall projector for super video graphics array (SVGA) signals. It is used as an image display unit, providing a large screen when several sets are put together.A high-quality picture has been realized by higher resolution and improved color uniformity technology. A new convergence adjustment system has also been developed through the optimal combination of digital and analog technologies. This video data wallinstallation has been greatly enhanced by the automation of cubes and cube performance settings.The P4140 video data wall projector can be used for displaying not only data but video as well.
