With the development of the times and economic progress, the computer network in the industry has been widely used, Multimedia technology to the display device and the function of the higher performance requirements. Therefore larger-screen projection system seamless tiling has become the most important one of the display device. Larger-screen display system is widely used in traffic control centers, command centers, television stations, industrial control, and so on. Video can be realized right signal monitoring, computer graphics control system, GPS and other computer images of integrated information, forming an accurate information, inquiries convenient, efficient management, aesthetics and practical information indicating management control system.
The topic of the design and production of an edge-blending processor of a DLP projection system, to achieve a high resolution of the images is divided into two sub-images, in part by two overlapping edges of the projection respectively. The first part of the overlapping image signal by integration function relationships Fade out of the edge of integration, superposed in partially overlapping traces can eliminate duplication and achieve seamless tiling of the goal.
This paper presents a larger-screen projection system shows the general structure, and analysis of the DLP Projection Display of physics; elaborate on the edge-blending Technology and Gamma correction principle; stated hardware system and device selection for PCB design, production process; plate MATLAB simulation through the integration of the results, the use of DVI interface with the LCD display shows the experimental results, PR650 against the use of spectral photometric / colorimeter to show results measurement; Analysis of the simulation, display and measuring results.
The seamless tiling DLP projection display system has good market prospects, is a projection of the importance of technology. In Nankai University photoelectron undertaken by the Ministry of Science and Technology 863 flat panel display support for the project, Lanzhou University, as joint training and Nankai University students I chose the seamless tiling DLP Projection Display System Study as my thesis topic.
