The pursuit of bright large screens, pure colors, and high-resolution display effects has always been a potential requirement for people to feel visually. Like command and control centers, network management centers, video conferences, academic reports, technical lectures, multi-function meetings, etc., the demand for large-screen presentations is increasing. The projection splicing system can just meet the needs of users. Large-screen, multi-color, high-brightness, high-resolution display effects can be achieved.
400-inch ultra-wide screen
In this plan, the ASK E1550 projector is selected, which has a high brightness of 5500 lumens, which can also ensure that the picture is clear and bright in a brighter demonstration environment.

The projection screen is a customized frame screen with a 180-degree viewing angle. The following picture shows the effect of the demo screen shot from the side, which is still clear and gorgeous.

Edge fusion controller The key part of the projection splicing system is the edge fusion technology. Whether the image connection is complete and whether the color brightness is consistent is affected by the edge fusion technology. Edge blending is to overlap the edges of the pictures projected by a group of projectors (two or more), and display a brighter, super-large, high-resolution whole picture without gaps through the fusion technology to achieve the effect The picture quality projected by a projector.
In the projection splicing system, the most critical equipment is the edge fusion controller. It determines the effect of the projected picture and the perfect connection of the two projected pictures. At present, the edge fusion controllers on the market, each device can be configured with a set of special software to adjust the brightness, contrast, image misalignment, proportion distortion and other problems of the picture, to ensure that the picture presented is a complete and seamless image.
The application of projection stitching has been very common at present, and the edge fusion technology as the core of stitching is also continuously upgraded. At present, the seamless edge fusion effect is the best, and the picture column and black border phenomenon will not appear in the picture.
The current mainstream seamless edge integration technology is mainly divided into the following four parts:
1. Edge fusion technology: the use of image stitching edge fusion technology to eliminate edge shadows, so that the entire screen achieves an integrated stereo panoramic effect, so that the viewer is fully invested in the virtual world;
2. Green Convergence Technology: The image stitching of multiple projectors will not cause misalignment and proportional distortion, and the green reference of each projector must be aligned;
3. Full-screen contrast modulation technology: For multi-channel systems, edge blending and contrast tuning can produce a seamless and the same brightness image. As a result, multiple projectors are added to create an immersive environment. Gamma correction in the mixing area ensures that the consistency of edge mixing is maintained at various video levels.
4. Extended geometry adjustment technology: In order to adapt to the focus and geometric adjustment of the curved curved screen, in addition to the special large-scale curved surface geometry adjustment lens, the extended geometry adjustment technology is also needed to ensure that the projector is projected at a large tilt angle and a large curvature In the arc screen, the range is fully adjusted. This adjustment capability ensures the accuracy of the image mapped on the column screen in multi-channel projection.
Summary: At present, the increasing demand for the number of theaters, coupled with the increase in the demand for large-screen displays in commercial venues, projection splicing systems will be used more. In the future, the demand for 3D super-large-screen images and the demand for 3D stereoscopic projection splicing systems will also increase significantly.
