I could be wrong but I think maybe Kobo was the first reader to do this.
My 5" Elonex 511EB allowed you to set the number of page turns before a full refresh. That came out in 2009. It was a great little reader for its time. (It was a rebranded Hanvon device, I think.)
The Kobo came out nearly a year later, in May 2010.
