An electronic screen is different in this respect. It combines brightness, image clarity and constant change of pictures. It draws your attention from a long distance, people start looking at it long before they can distinguish the image details. This is how human brain and sight works: we are attracted to anything that moves.
The eye structure determines that a sharp image on the retina is located in the central part of the eye. Thus, everything that did not cause interest and did not result in subconscious focusing on an object, stays in the background, barely seen, as if through the dark-stained glass.
Therefore, good commercials displayed on a good electronic advertiisng screen have a perfect efficiency. Since the screen is located along the main Californian highway (densely populated and rich area), it guarantees high return-on-investment for both screen manufacture and advertising time.
Since the advertizing screen is installed in a “quiet” spot – long straight stretch of the highway – it does not negatively affect the safety of driving. The images are changing in the slide-show mode, that is it is a simple change of images without special video effects. This makes you think about poor software that does not allow to view video and to link images by special effects.
However, the reason may also be in the low capacity of video controller that is unable to process video stream. At least this is what manufacturers of similar systems believe. Indeed, live video requires nearly 30 times higher flow band compared to separate slides that change once every second (in reality even slower than that).
It is important to remember that an image on a large high-resolution LED screen contains more information that an image on a similar sized lamp screen.
Thus, if the LED screen was built on a “outdated controllers” to make it cheaper, narrow flow bands will prevent live video broadcasts.
It is most discouraging, because this drastically limits the capabilities of such a wonderful screen in advertising commercial products. Some products have to be displayed in dynamic motion, like cars, for example. Other products, like tourist services, freight etc. may need less of live video effects.
To conclude: the appearance of a purely commercial electronic screen that sells advertising time is a new approach for the USA, though in many other countries this has become traditional. The site for the screen is selected from the viewpoint of covering the largest audience. The advantages of the electronic advertising screen are: large image area, positioning, full-color capability, brightness and high resolution
