What should a Bus Led Sign or Bus LED Display Cost?
The purchase cost of bus led sign, bus led displays or electronic bus billboards depends consists of A) screen cost and B) the Led system ( including installation and operation). The former depends on three key variables. Those three variables are the 1) total size of the Led screen, 2) the pixel resolution of the led screen and, 3) the brightness of pixels.
(1) The total size of the bus Led signs: the bigger or larger the Led signs the higher the cost for similar Led signs. The prices are based on per square meter, which means that if the total size is N square meters, the price will be N multiplied by the cost of per WQM;
(2) The pixel resolution of the screen: The more pixels, or the more number of LED’s, the screen has the higher the cost will be. For example if a P4 bus screen sign is 2sqm and has 12500 pixels, it will be cheaper if the P5 LED screen sign is 2sqm with 80000 pixels. This is because more Led lamps will be placed onto the screen sign which is a higher cost. But on the other hand the more LED’s the screen has, the higher the detail will be of the videos and images that the Led screen sign will publish;
(3) The brightness or contrast – while the size and resolution determine the viewing pixel matrix and granularity of the image displayed it is the lighting contrast of Led sign with its environmental backdrop that determines the viability of display image. For example, a larger P10 SMD semi-outdoor Led screen of low brightness may be washed in the sunlight and not be as viewable in any range compared to a brighter and smaller P8 SMD Led screen
.
A brighter screen sign with lighting control will save on power consumption and provide best viewable and visible image and may cost more to purchase but will cost far less to own due to operating expense and life-expectancy (replacement cycle).
The cost of ownership of Led screen sign is the sum of purchase and installation / operation costs of the led over its life-circle (less the revenue it generates). Of the two costs the cost of ownership is more important factor than the cost of purchase. In reality, it is the capital expenditure or the budget that usually becomes the deciding factor for in-experienced users.
It is important to note that in any circumstance there is only one ‘best solution’ as compared to many cheap or inexpensive options. The best solution takes into account not only the costs but also the revenue potential and measures the impact on the bus advertising business.
