Alaska Airlines Boarding Display

This is the best airline boarding sign / display I’ve seen to date. Its by Alaska Airlines. The display hangs close to the gate and prior to boarding has things like departure information (or arrival info if a flight is arriving). When the airline is ready to get people on board, the display switches to this image. It quickly lets you (a passenger) figure out if your row is boarding or not.

At some point in the future I hope to see the displays include a diagram of the rows indicating which rows are boarding. Many flights board “from the rear of the aircraft”. A diagram showing the rows would make this easier to understand.
