Hi, I am looking for an LED display screen which can be placed atop a table and can run ads. The screen should run a program to sync data related to ads shown. I found several screens online which run android OS and have RAM and storage which can do the job but this is out of budget. What is the best and cheapest way I can achieve this? Can I do this with just a screen without an OS but connected to a Raspberry Pie? I want the best affordable solution.
