In traditional video wall, when the image projecting of different display modules is in the different parts of display surface
When.Because image is to be in the state expanding amplification, with regard to different display modules image projecting in aobvious
Show the light beam on the adjacent edge part of different parts in face, its direct of travel is simultaneously incomplete same, such as
This will lead to user watching the adjacent side that display surface can find to be projected on the different parts of display surface
The light intensity of upper two images of edge part simultaneously differs, and allows user perceive the side of display surface difference part
Edge, so that display surface cannot show globality.
In order to solve foregoing problems, if display device 100 increases the first display module 200 and the second display
The projector distance (Throw Distance) of module 300, then can make the 3rd reflected image 440 anti-with the 6th
Projection is projected on the first display surface 210 and the second display surface 310 as 540 in the way of being similar to collimated light beam
