Boox devices running Android have 3 user-adjustable levels of screen refresh. The higher you go, the more battery it uses, but higher levels let you browse the web relatively well.

And the higher you go the more ghosting you get and the contrast level drops sharply.

They increase the refresh rate by both boosting the voltage and limiting the dynamic range of the screen.
