That's incorrect.
The
screen doesn't use any power when it's not doing a page turn, but an eBook reader is a computer. It has a CPU and memory, all of which use power, just like they do on any other computer.
Generally, "stand-by mode" puts a device into a very low power mode, where the CPU is "hibernating" and using a lot less power than it does in normal operation.
