Principle and technical superiority of projection fusion technology

Projection Fusion technology is a set of projector projection of the screen edge overlap, and through the fusion technology to show a no gap more bright, super large, high resolution of the whole picture, the effect of the picture is like a projector projection of the screen. General principles of Projection fusion
When two or more projectors combine to project a picture, there will be a part of the image overlap, the most important function of edge fusion is to reduce the brightness of the overlapping parts of two projectors gradually, so that the brightness of the whole picture is consistent.
Now there are a lot of stitching on the market, such as LED splicing wall, TV splicing wall, projection box splicing wall, etc., but relative to different applications, led mosaic wall and projection cabinet wall is always composed of a picture of a jigsaw puzzle, so that the integrity of the picture will be affected. Edge Fusion Technology is a new seamless splicing technology in recent years, which improves the visual effect of stitching image better.

Technical Advantages
increase image size and picture integrity1. Increase image brightness
2. Increase resolution
3. Ultra-High resolution
4, shorten the projector projection distance
5, special shape of the screen projection imaging (such as ARC screen/spherical screen)
6, enhance the image level sense
increase image size, picture integrity
Obviously, more than one projector projection of the screen will be more than a single projector projected out of the screen size larger.
Bright and beautiful picture, will bring people extraordinary visual impact, and how to eliminate the picture splicing optical gap it?Edge BlendingTechnology solves this problem. The advent of this technology, to a greater extent, to ensure the picture of the perfect and color consistency.
The advantages of the full picture do not require too much representation, because the display of the perfect picture is always at a glance for the appreciative person. Projection fusion increases the layering of the video
Increase image Brightness
When the projection size of a projector is enlarged, the image brightness will be reduced, while the same brightness of the projector with more than one projection of the same size image can maintain the original brightness of the picture.
Increase resolution
Each projector casts a portion of the entire image so that the image resolution is increased. For example, the physical resolution of a projector is 800*600, three projectors fused 25%, the resolution of the image becomes 2000*600
Ultra-High resolution
Image processors and computers with multi-channel high-resolution output can produce synthetic images of three or more channels per channel of 1600*1200 pixels. If you blend 25% pixels, you can produce 4000*1200 resolution images by subtracting the extra overlapping pixels. There is currently no standalone display on the market that can operate at such high resolution. The solution is to use the projector matrix, each projector is operating at its maximum resolution, the resultant resolution is subtracted from the overlapping region after the sum of pixels.
Shorten projector projection distance
With the appearance of seamless splicing, the shortening of projection distance becomes inevitable. For example, the original 200-inch (4000*3000mm) screen, if the requirements are not physical and optical stitching, will only be a projector, projection distance = lens focal Length * screen width, even with 1.2:1 wide-angle lens, our projection distance is 4.8 meters, now useEdge Fusion Technology, use 4 projectors to project the same size of the screen, the projection distance of only 2.4 meters.
special-shaped on-screen projection of images (e.g. curved curtains/spherical screen)
For example, projecting a picture on a cylindrical or spherical screen, a single projector requires a far distance to cover the entire screen. The combination of multiple projectors because each projector projected a smaller screen, so the distance is also shortened a lot. Layered sense of projection fusion screen
A more important feature is that if you only use one projector to project the entire ARC screen, it is difficult to focus because the arc chord is too large to pick a suitable benchmark focus. More than one projector can shorten the arc chord distance to as small as possible, so it is easier to find the appropriate focus of the screen. For curved or spherical screen applications, useEdge BlendingTechnology is a better choice for image resolution, luminance, and focus.
Increased screen layering
Due to the use ofEdge BlendingTechnology, the resolution of the screen, the brightness is increased, at the same time with high-quality projection screen, you can make the entire display system of the screen level and expressive performance significantly enhanced.
