Abstract

The invention discloses a screen splicing display system used for long-distance pipeline coal transporting integrated dispatching. The screen splicing display system is formed by splicing at least 32 narrow-side digital information display (DID) systems of 46 inches. The splicing way is 8*4, i.e. 4 rows of narrow-side DID systems are arranged transversally, and 8 rows of narrow-side DID systems are arranged longitudinally. The maximum splicing gap of the screen splicing display system is 7.3mm, and the splicing effect of the screen splicing display system is close to a seamless splicing effect. A high-reliability SAMSUNG DID liquid crystal screen is selected as a splicing large screen, and the service life of the SAMSUNG DID liquid crystal screen is 60 thousand hours at least. The contrast of the liquid crystal screen is 3000:1, the wide extended graphics array (WXGA) resolution is 1360*768, the brightness if 700cd / m<2>, the display color is 16.77 million color, and the visual angle is 178 degrees. By utilizing the large screen splicing display system disclosed by the invention, concentrated displaying can be performed on a computer image-text signal and all front-end video signals of a pipeline coal transporting integrated dispatching management system. The screen splicing display system can be used for the aspects of real-time dispatching, conference, decision and information feedback and the like, and is wide in application prospect.

Description

technical field [0001] The invention relates to a pipeline coal transportation project, in particular to a screen splicing display system for comprehensive scheduling of long-distance pipeline coal transportation. Background technique [0002] Video walls first appeared in the early 1980s. For example, the video wall that first appeared was the splicing wall that appeared at the Funkaustellung Exhibition in Berlin in 1978; the 4×7 video wall was installed in the EPCOT Aquarium in 1986; the Philips Vidiwall installed in the Canada Pavilion at the Vancouver World Expo in 1986 He has won the IfoComm Outstanding Achievement Award; in 1987, the Hippodrome nightclub in London installed a video wall consisting of 108 monitors in order to please club members; in the telecommunications pavilion of Expo92 in Seville, Spain, a video wall consisting of 160 monitors was also installed. A video wall consisting of multiple monitors. However, due to the limitations of equipment and techno...
