If I remember some e-paper displays used fast refreshes to display grayscale colours. Since the display could not refresh as fast, it would be grey.

Hello sir, I see you've been offline for over the past 4 years. Did something happen or are you building something for your viewers? I'm just concerned because when a creator is offline for more that 4 years, I get concerned something happened to them. Please post something soon to update your viewers.

You haven't updated your website either....... So that makes me even more concerned.

Hi Dan Ehrman, That is really fast. Can I please see your source code? I am currently using 2.7' B version of E paper along with a ESP8266 driver board. Thank you :D

Hi , i dont understand why your display doesnt change to black before changing content , most others ive seen do that. would you share a modelnumber of your display ? thx

Linux Cow im pretty sure the thing about changing to black is just a preference to articulate the changes and not make it look blurry. I'm pretty sure there's something mildly similar to this on those old film players (with physical frames) where they had something synced with the normal spinny thing that would block the light for a tiny fraction of a second while the film was transitioning from one frame to another. Then they made it go at around 26 fps because that's when things like film start to look less choppy and more fluid (or something like that)... I need to stop rambling.

It's called partial update. It's basically an algorithm which involves resetting to white before loading a new graphic. Your capability to do this effectively and efficiently depends on the particular model of display. More modern displays can do this almost instantaneously, with a refresh rate of almost 20 Hz in some cases. Drawing tablets such as the Sony DPT-RP1 and the reMarkable are examples of this. It is limited to the amount of content being displayed at a time, however. Today, something like rendering a video or a game is impossible, I am afraid. A way to overcome this is to process several parts of the E-Ink display separately. The aforementioned drawing tablets to something like this, and process the display in quadrants or several squares by multiple processor cores at once. In this way it is possible to make the display almost pixel independent and render complex graphics.
