Why Curved? The main benefit of using curved screens for visual displays, is that for known viewer position, a screen with the same physical screen size produces a wider field of view for a curved screen than a flat screen.	Overlap Regions Before edge blending can occur, the projectors and software application need to be set-up so that an overlapping region between the edges of adjacent projectors is present.	Edge Blending Edge blending is a technique used to describe the process of visually combining several projected images to make a single seamless image. Typically, this is done to increase the size of a projected image to make a very wide image, or by combining a number of lower resolution devices together to increase the total resolution of a display. In both cases, a number of projectors are needed which are firstly overlapped and then visually joined together using an edge blending technique.
Geometric Correction Image warping (geometric correction) is used to make an image look visually correct when it is projected onto a non-planar screen. This process is also referred to as distortion correction or geometric correction.	Multichannel Displays Multichannel display set-ups are used when more than one projector is needed in a display system. This maybe because an increased field of view or a higher resolution displays than that offered by a single projector is required.
