【 Weak current College 】 edge integration projects require attention to detail

Edge integration project is a face-saving project, but if you listen to some professional advice, take it for granted that: "rest assured, the edge and merged the not so hard!", the project is likely to become a face of the project. Projection screen, projection machine, projector hanger wire structure, projection, brand, etc. every detail you need to be aware of.

Projection screen, select

Edge integration project projection screen generally use easily fixed metal hard curtain, screen gain also as small as possible, generally less than 1.2. Fusion band section is two sets of projector image overlay. Two projectors occur subtly displacement, overlays section will produce images overlap and color transitions not natural, incoherent. Similarly, if the screen had slight displacement would produce ghosting and screen tearing. Metal hard curtain easily fixed, and look upscale atmosphere, large-screen projection edge integration project recommends using metal hard curtain.

The gain of the screen also need attention. The gain of the screen, the greater the Visual angle; the larger the screen's gain, the smaller the Visual angle. If positive, gain a large projection screen and gain a small projection screen of fusion effect there is no difference. But if you are installing from a larger perspective view, gain a large projection screen of the integration with the more obvious that the overall picture is strong enough.

Large-screen projection of seamless mosaic project, using gain small projection screen will make the picture from different angles to watch a whole such as always, the effect is more ideal for large-screen projection edge integration project recommends using gain a small projection screen, the gain in 1.2 following.

Edge fusion band width

Large-screen projection is it sew concatenation, edge integration project, how to determine the width of the edge fusion band, how to determine the dimensions of the projection screen? because to do edge fusion, adjacent projection projector screen needs to have some heavy, heavy match the width of the section should not be less than the width of a single projector projection of 20 per cent.

The edge and merged the large-screen projection, projection and selection of wire

Projector signal transmission quality is not good, bad or immunity to length is too long, the projection screen may appear out of the tail, dynamic ripple or shaking. Project hope to avoid commercial follish rewiring.

Edge integration project, the selection of the projector

Big screen seamless projection, edge integration project, the selection of the projector to note the following:

1. choose the DLP (digital) technologies, the projector cannot take the LCD (LCD) projector technology.

In Fusion splicing project not using LCD projector is an important reason is: LCD projector use for a period of time (approximately 200 hours) chromatism, appears after destroying the integrity of the screen. The effects of chromatic aberration occurs as follows:

LCD projector LCD Panel due to its own characteristics, in use for some time, the overall picture colors too red, blue or green offset, and color deviation is erratic. Is likely to make Fusion 2 machines, one color is red, one blue color bias, the entire screen is divided into two parts, undermine the integrity of the screen.

Because the projector more than 99% of applications are single-projector projection, a single projector is chromatic aberration users simply cannot detect, so LCD projector this feature has not been mentioned. While a large number of projects it is proved that the LCD projector is suitable for integration, when two projectors put together, this difference will be obvious.
While the projector DLP digital technology has no such defects, fusion project it is best to use DLP digital projector. If you deliberately use LCD projector will make the project failed.

2, the projector's lens does automatic drift or reset.

Some projectors on the market, each boot when the lens is automatically reset. This projector is used on a single projector projection of occasions, the relationship is not significant, because a single projector can use before doing a simple rapid adjustment calibration and adjust immediately put to use. But if edge integration project, the projector lens drift back again adjust the fusion band, fusing belt adjustment takes relatively more significantly affect actual use. If you want to do edge integration, selection of projector models tell us, or we recommend projector models.

3. other considerations of projector.

Projector projection distance also needs to pay attention, because the edge and merged the required maximum projection projector range than a slightly larger screen (projection of above and below the screen size greater than 8 cm or so, as far as the projection position level), random selection of projectors that projector lens, screen size and projection distance and other factors.

Big screen edge fusion engineering requirements for projector hanger

Large-screen projection is a relatively high-end application, the requirements of the various equipment are as sophisticated, accurate and attractive. Projector hanger choice or belittled. Because to do Fusion splicing, the projector position slightly move may make screen display with ghosting, or fine image text, Ghost effect will be more obvious that significantly affect the overall effect of the picture.

A rugged, design reasonable hanger will let project more quickly and smoothly, to customers efficient, professional feel.

We have encountered some projects, the project developers to save a little bit of cost, or for other reasons, did not pay attention to the choice of projector hanger. Results in the construction process, find the angle adjustable hanger, aerial work, because it is a few people had a lot of effort to make the screen to the screen. The screen shot to the screen, and found the projector hanger can not be fixed, a slight vibration will shift. On the top of the ceiling often have air-conditioning outlet, outlet of the projector, Fusion better transposition of the screen and in a few days appeared toLight and shadow, are not. There is also the projector hanger and projector do not match, the first hanger load and does not match the weight of the projector, and secondly not hanging up the focus of the projector, for a period of time, because of gravity, projector, offset, screen of the overall effect has been destroyed.

Although the edge Fusion Debug can give the owner training, but the projector hanger usually occurs at the offset of the completion of the previous period, the project has not yet been billing, party a party b has yet to master the method of debugging, the debug constant maintenance costs will be significantly increased. But even if party a mastery of the debugging methods, frequent debugging will allow the owner to the edge and merged the doubts of mature products.

Large-screen projection, have not sewn the concatenation, edge Fusion is a systems engineering, occurring in the projection screen, failure ghosts that might be due to a mobile projector hanger, projector lens shift, projection and wire quality and immunity is insufficient and so on. At this point, so that every part possible perfect can significantly reduce troubleshooting time.

Overall, the projector hanger is a big-screen integration project of an important part, try to fine tune the procurement, around can be easily fixed, earthquake and load appropriate, hanging up weight, appearance of projector hanger.
