That first board is just a list of departure times by hour, with express trains highlighted. For weekdays and weekends. Not exactly a huge amount of information.

I'm more impressed by their maps of where each station exit leads to, or where on the platform to wait based on your seat number. Those can be tricky to figure out as there are multiple wait points based on the train route and number of carriages. Shinkansen even take into account what end of the carriage you're closest to.
