Digital billboard is expensive. If there is no access to the power supply, then it is doubled and triple expensive. New technology will reduce maintenance costs in 10 times or more.
The main reason why digital billboards aren't ubiquitous is the lack of high-wattage power supply. There is 1 mln billboards in the world. Only 10% of them are digital. 800,000 traditional billboards have no access to high-wattage power supply. In some cases, they source power from the lightning systems.

Digital billboards have only been installed in locations with high-wattage power supply. In other locations, supplying 1kW may cost up to several thousands of dollars.
Powering a billboard may cost more that the billboard itself. This is the problem of highways that connect big cities and airports. Busy highways are perfect locations for digital billboards in terms of audience. However, there is no power supply there.
There is a clumsy solution if there is no access to the network. If there is no power supply, you can use a diesel generator to power a billboard.
The biggest con is that a diesel generator needs to be refueled every day. Power produced by a diesel generator costs 3-4 times more than the power from an electrical power line. Plus, a diesel generator needs to be maintained every 8,000 hours. It needs to be reassembled once a year. Maintenance costs of a diesel generator come close to the cost of a digital billboard. As a result, this pushes ad placement prices up.
How to solve the problem more economically?
Ledder's screen will have built-in solar batteries. This way, solar energy will power the screen at daytime and charge the batteries. The batteries will power a billboard at nighttime.
Solar batteries and LED are highly effective solutions. The production costs of Li-Ion batteries dropped to 100$ per 1kWt-hour. The production costs of solar batteries is now at 50$ per 1 sq. meter. Most of the billboards will be digital and solar-powered in the upcoming years.
