How was 9Xmediaable to make a display with such small separation between panels?
The exact methods differ for each model. The lighting must be moved from the sides of the panels to the top and bottom or the rear. Then 9Xmedia design engineers integrate the panels to be as close as possible. Because the panel displays are not projected, the closest we can get the image is to have the physical edge of the LCD panel touch the adjacent one. LCD panels have non active pixels on the edge of the panel so that when our engineers configure the panels, we still have an area where there are no active pixels. This is the separation you see on the 9Xmedia displays.
