           | 
           | Hard disagree. E-readers already do this and are 2 orders of
           | magnitude cheaper. Long-form text content barely need 1 Hz
           | refresh rates.

           | involve looking at a screen all-day don't really require high
           | refresh rate screens. The main exceptions are any folks doing
           | design or editing work. This is a huge game changer for the
           | vast majority of folks on HN that are looking at a terminal,
           | text editor, or docs for 90% of their day.

             | The problem with such low refresh rates is that your eyes
             | may have to work much harder to locate where you're at
             | after you've scrolled the page.
             | 
             | Not all content is formatted to never break sentences or
             | paragraphs, and not all software even supports pagination
             | as an alternative to scrolling.

           | 
           | That's because it does not refresh the display when drawing -
           | it transitions the pixels directly (it's called a direct
           | update, or DU mode). I worked on the third-party SDK for this
           | device (hi!) and the DU modes do suffer from ghosting
           | (similar to e-ink monitors) until the display is properly
           | refreshed to correct the charges in each pixel, but this
           | ghosting is typically not too bad when drawing, especially
           | since there is typically a full refresh whenever you zoom,
           | pan, or switch pages.

               | What I intended to propose was, _there may be unexpected

               | selected matte film applied to it; you buy an EPD display

               | I said that this is inherent to the outmost layer that

               | displays with front glass.

               | A good matte display (via coating in-factory or via film
