Seven main factors affecting the design of edge fusion system

Large visual electronic Edge Fusion Display system is a professional, complex video display system. In the design of the establishment must be considered carefully, eliminate all kinds of undesirable factors. Because the edge fusion system construction has the related equipment many, the system connection is complex, is susceptible to the environmental factor disturbance characteristic, therefore if did not have in the design initial consideration thorough, chooses the unsuitable equipment or the hoisting method, will bring the extremely difficulty for the late project implementation, the serious time even must cause the rework.

first, the projectorThe selection of the projector should be used as an important part of the preparation of the project, the choice should avoid multiple projectors between the brightness and color differences too large (recommended should be more than twice times the number of selected color to restore the most close to the group). Hoisting should choose a solid and reliable hanger, to ensure that the projector is stable and strong lifting, at the same time to ensure that the lifting approval to facilitate manual position adjustment. second, the type of the screenCan be used according to the actual situation of white plastic screen, metal screen, high-energy curtain, glass bead screen, and so on, because of the edge of a single projection of the screen than the requirements of higher, so should try to choose a good visual angle of the screen, not simply the pursuit of high efficiency. third, the screen gain and half-gain angle of viewA higher gain rate increases the brightness of the projection, but at the same time affects the viewing angle of the screen, which affects the fusion effect. It is necessary to consider the equalization of gain and semi-gain angle of view when selecting projection Fusion screen. The larger the half-gain angle, the more uniform The scattering light is, the less likely it is to observe the boundary of the fusion band and the better the fusion effect. Four, the uniformity of the screenHigh uniformity of screen is required to ensure the overall color symmetry of the picture. v. Smoothness of the curtainSoft curtain smoothness is susceptible to external factors (stent deformation, air conditioning wind, etc.) are not recommended to be used. Hard curtain installation should pay attention to flatness, can not appear protruding or concave, otherwise it will be easy to create a picture deformation. Vi. depolarization of the curtainFor polarization 3D (polarization type) projection Fusion, the curtain is required to be non-depolarization screen. (Generally, the gain of non-depolarization screen is very high, at least about 2.0, suitable for polarization 3D projection fusion system) Vii. Wire and cableIt is recommended to use DVI digital signal transmission. VGA cable transmission is susceptible to external factors, resulting in different degrees of drag tail, jitter, attenuation, ripple or manic point, etc., seriously affect the final image quality of the system. Twisted-pair or fiber-optic transmission is recommended when transmission distances exceed 15 meters.http://www.mviewtech.com/
