Here's the Wikipedia article on teh Datapoint 3300, "one of the first glass TTYs". The article goes into more detail about shift-registers being used as the screen memory.

Shift registers are a lot simpler than RAM. There's no addressing logic. There are no address pins.

Early versions of the Datapoint 2200 came with shift register memory.  However all the ones I worked on had dynamic memory.
