What is Edge Blending Technology

Edge blending technology  is to overlap the edges of the images projected by a group of projectors, and show a brighter, larger and higher resolution whole picture without gaps through fusion technology. The effect of the picture is just like the picture quality projected by a projector. When two or more projectors project a picture on both sides, some of the image lights will overlap. The main function of edge fusion is to gradually lower the light brightness of the overlapping part of two projectors, so that the brightness of the whole picture is consistent. Edge blending projection technology has experienced three stages of development:  hard edge stitching, overlapping patchwork and  edge blending technology . Hard edge stitching(simple stitching): it refers to the edges of the two projectors are aligned without overlap. The display effect shows that the whole picture is divided by a seam. If the projector edge is not enhanced with brightness, the seam is shown as bla...

Projector Resolution and Contrast Selection

Resolution: the projection resolution can be selected according to the actual projection content for deciding what grade of projector to buy. If the demonstration content is dominated by general teaching and word processing, you can select SVGA(800 600); if the demonstration of fine images (such as graphic design), you can choose  XGA(1024 768) . Since the mainstream resolution of laptop and desktop is to meet the XGA(1024 768) standard, it is recommended to choose the projector with the  XGA(1024 768)  resolution if the budget allows.  No matter what kind of digital products, the resolution is everyone's concern factor. Common resolutions and representations are as follows: SVGA: common resolution for 800x600 budget projector  XGA:  1024x768 projector  resolution for mainstream business and education projectors 720p: 1280x720 or 1280x768 mid-range resolution for home projectors 1080p: 1920x1080 or 1920x1200 resolution for high-end home projectors At p...

The Projection Depends on Which Parameters

The following mainly describes  how to choose the projector , involving some of the projector function and parameters of using experience. Lumens can be directly understood as brightness. The higher the lumens are, the more they can be used in the daytime when the light is strong. Theoretically, taller lumen is better, but generally is more expensive. when see a film we always pull a curtain commonly to make the atmosphere in the home dark , so domestic expenses does not need too tall,1000-3000 is ok. Lumen has ANSI standard and IOS standard, just look at the ANSI standard, the above said 1000-3000 is this standard, If you see a merchant on the Internet whose standard is IOS standard, you need to make it 6 times smaller to be equal to the ANSI standard value. You should pay attention to this to avoid being poked. Contrast, you don't have to understand what the contrast does, the translation is that contrast is proportional to sharpness, the higher the contrast, the better, and cert...

How to Overlay Projection of Two Projectors

Laser projector suppliers Shanghai DIDON Industrial Co., Ltd. wholeheartedly provides customers with high-quality projection solutions. Usually, according to the situation of the project site, if the distance is long, the environment in the room is brighter, and the brightness of using a DIDON machine is certainly not enough, so two DIDON projectors are needed to superimpose. Superposition is widely used, and lumen superposition of projector is an important aspect.  The advantages of projection superposition and the equipment used: 1.Ultra-high brightness and ultra-low-cost Superposition system is suitable for users with brightness requirement of 7000 A NSI lumen or more. But the price of 5000 ANSI lumen or more is extremely expensive. In order to save cost, many users have to sacrifice brightness, and then choose a projector with lower brightness and lower price to replace it. The use of the two-machine superposition scheme, you can exchange for a very small investment in hig...
