Recently, a laser DLP display system of Delta has been installed in disaster prevention center of the provincial weather bureau in North China. A set of 2*12 70″ large laser DLP screen splicing system provides comprehensive information display with high brightness, high definition and high intelligent control. It undertakes the role of the provincial weather forecast and the emergency command platform for decision-making on disaster prevention and reduction.

To enhance the pertinence of weather forecast services, weather forecast services have become increasingly refined, and the demand of meteorological departments for large creen display with high resolution has been increasing day by day. To improve the warning and emergency mechanism of meteorological disasters and to minimize losses caused by disasters, meteorological departments have increased the construction of “weather disaster warning platform” in recent years.

According to the special requirements of the weather bureau, Delta has built a set of 2×12 single-screen 70-inch laser DLP large screen splicing system, which adopts the fourth-generation light source (laser) DLP display unit to provide LED light source with ultra-high brightness, high contrast and high uniformity. It also exceeds the ultra-wide color gamut range of Rec. 709 (ITU HDTV color standard), provides real color performance, and achieves high display resolution, so the display of cloud chart is richer and more delicate. With a wider range of brightness control and constant color temperature, it can better ensure the brightness and color uniformity of the whole screen. The life of the light source can reach 60,000 to 80,000 hours, saving a lot of maintenance costs in the later period.

After the establishment of this laser DLP large-screen display system, the weather bureau can watch and monitor various relevant information in real time, including cloud chart, GIS electronic map, real-time video monitoring signal, management information system data, history data image and other information from signal sources like computer, television, projector, DVD and computer network and so on. Judgment can be made and instructions can be issued in time, and the purpose of real-time warning and decision-making can be realized.
