Analysis of Rear Projection Splicing Application of Safety Production Testing Platform

There are 4 large screen splicing methods, including DLP splicing, LED splicing, LCD splicing and PDP splicing. DLP projection stitching is gradually maturing. For many years, DLP rear projection splicing has always occupied the leading position in the whole large screen splicing market, and no one can shake the dominant position of "zero splicing" with its unique super-large format and low price. For the large screen display field, the pursuit is three points:
1, larger. larger display area,
2, higher. Special, higher display resolution.
3, thinner. The thickness should be as thin as possible, and the display device is relatively easy to install.
4, more stable. Better stability, strong and durable. Comparison of Large Screen Splicing
Through the above horizontal comparison, we can conclude that the advantages of large screen display, projection DLP splicing and LED splicing are very prominent. In simple terms, rear projection splicing can be divided into: single-machine single-screen single-picture rear projection display application mode, single-machine single-screen multi-picture rear projection display application mode, multi-machine single-screen rear projection display application mode, multi-machine multi-screen rear projection display application mode, back projection display wall, etc.
Analysis of Application Characteristics of Rear-projection
The project rear projection stitching adopts professional rear projection optical screen, which can provide clear and bright high contrast images. The convex lens built in the screen can help focus, improve and control the projected image, and effectively overcome the key problems such as ambient light, radiation light and wide viewing angle.
Rear projection display scheme
DLP rear projection stitching application adopts rear projection optical screen, which can meet the requirements of high quality picture, large viewing angle, various display proportions, short focus lens and edge fusion. Rear projection application screen requires different lighting forms from LCD and PDP. DLP projector is a point light source imaging mode. Point light sources need to be eliminated or infinitely dispersed, which is impossible for diffuse reflection screen. The optical screen using Fresnel lens and convex lens technology can effectively eliminate uneven brightness and staircase effect caused by point light sources, is suitable for various flexible display ratios, and can be used for edge fusion display of various sizes. Rear Projection Screen Material Analysis
Rear projection stitching, the use of optical screen technology content is higher, the best imaging quality, relatively the highest cost.
Rear projection stitching application field
Rear projection splicing display, the biggest advantage is not affected by ambient light, the use of high-end optical rear projection screen, the picture quality can meet the application needs of most industries. The rear projection stitching mode can still realize the uniformity of color and the unity of brightness in the multi-screen rear projection stitching mode. Of course, the best use of rear projection splicing is interactive application, which can not only ignore the interference of external ambient light, but also avoid the eye damage of projection light to the user, and directly carry out handwriting interactive operation at close range. At this stage, rear projection splicing mainly appears in places such as large-scale building central control, coal mine monitoring, high-end commercial display, and large-scale exhibitions that pay attention to picture details.
Analysis of Safety Production Application
Rear projection splicing applications, in the current market, the use of fewer people, because of its high cost of implementation. However, compared with the effect of direct projection splicing, the rear projection has obvious advantages. The rear projection splicing display is not affected by ambient light, and can ensure a clear output picture in different environments. Rear projection splicing requires the projector to have a short focus function in order to save floor space. In addition, the projection screen also requires a special rear projection screen, and the selection of the screen directly affects the effect of the projection screen. The rear projection splicing scheme of Yuchen high-end display experience center uses a high-end translucent rear projection curtain, which can help the projector achieve better results.
