TECHNICAL TERMS
Our team at EBILLBO, LLC has assembled a cadre of vendors and suppliers whose sole focus is to deliver our customers the highest quality mobile advertising solutions (mobile billboards and mobile LED signs) available today. As we assemble the final product here in Southern Nevada our Quality Control team rigorously inspects each unit to ensure it will not only meet but exceed your expectations. As such, we have developed this website to serve as a clearinghouse for information pertinent to our operations. Consequently, we have created this page to provide additional clarity on industry specific terms.

PIXEL PITCH
What is pixel pitch? Quite simply it is the distance from the center of one LED module (the key component on our mobile billboards) to the center of the adjacent LED module. In our industry LED modules are often classified by their pixel pitch.
Our E-500 Mobile Billboards have a pixel pitch of P5, which means there are exactly 5mm when measured from the center of one LED module to the center of the adjacent LED module. Our E-600 Mobile Billboards have a pixel pitch of P6, which means there are exactly 6mm when measured from the center of one LED module to the center of the adjacent LED module.
From a resolution standpoint the lower the ‘P’ value, the higher the resolution. The net result of selecting our E-500 Mobile Billboard instead of our E-600 Mobile Billboard is an approximate increase of 33% more LED modules in the same predetermined space. However, there are several factors to consider when determining which application most suits your needs including optimal viewing distance (see below), brightness, and power consumption.
In rudimentary terms, as you increase the resolution, the screen brightness (measured by NITS, see below) decreases, while the power consumption increases because of the additional LED modules. These factors may ultimately determine which model will best suit your specific application. The highest resolution screens (lowest ‘P’ Value) are often used indoors, where power consumption and screen brightness are not as high of a concern.
OPTIMAL VIEWING DISTANCE
Optimal Viewing Distance is the point at which you stand before an LED display and the image fidelity is maintained, yet if you were to move closer, the image fidelity would be degrade and the image may appear pixelated. Though you may be tempted to secure a screen with the highest possible resolution, other factors such as power consumption, cost of goods, and screen brightness should also factor into your decision.
NITS
The term ‘nit’ originated from the Latin verb nitere, which literally means ‘to shine’. For our application (mobile LED billboards), the term refers to the measure of light emitted on a specified surface, which is used to articulate the specific level of brightness of the light emitted from a particular billboard.
Why is this important? To be effective a billboard must be highly visible. Given the intensity of the sunlight in the American Southwest we have secured the LED panels, which produce a maximum of 6,500 (+/-) NITS, which make our mobile billboards ideal for use during the daylight hours. However, in conjunction with our software suite our mobile billboard hardware automatically senses the surrounding environment and adjusts the brightness of our mobile billboards accordingly.
IP RATING
‘IP Ratings’ are a globally recognized international protection rating system. IP is an acronym for ‘ingress protection’ and specifically alludes to a level of protection afforded by a given electrical enclosure. The utilization of an IP Rating allows for a more accurate evaluation of a cabinet than simply stating the enclosure is ‘dustproof’ or ‘waterproof’.
The first number in an IP Rating refers to an enclosure’s ability to protect internal electrical components from solids and can range from 0 to 6. The second number in an IP Rating refers to an enclosure’s ability to protect internal electrical components from liquids and can range from 0 to 8.
Our mobile billboard enclosures have an IP Rating of 65. Which means, according to the provided scale, our cabinets are ‘Dust Tight’ and show no ingress of dust during testing. In addition, they are ‘Protected against water jets’ and that water jets, sprayed from any direction, will have no negative effects on the operation of the unit.
SMD LED Technology
SMD an acronym for ‘Surface Mounted Diode’ is the newest evolution in LED lighting. Due to their construction the units themselves are smaller and as a result can be grouped closer together than their predecessor, DIP or ‘Dual Inline Package’. This grouping allows for a higher resolution display and one which is more energy efficient and longer lasting than DIP LED lights.
Asynchronous CONTROL CARD
In the context of mobile LED billboards, there are two distinct types of ‘Control Cards’ used to regulate the image on a billboard, asynchronous and synchronized. Our mobile LED billboards utilize an asynchronous control card, which simply means our control card has a memory function that allows it to store an image or images for display on the billboard. The operator creates an image, which is then processed by our software suite, and uploaded to the control card via a WIFI or 4G Connection. The image(s) are then stored in the control card’s built-in memory for display on the mobile LED billboard.
Conversely a synchronized control card would require a computer to be present and connected to create the image, upload the image, and control the mobile LED billboard. Utilizing an asynchronous control card proves far more economical as it removes the necessity of having a computer always present with the mobile LED billboard.
