The answer I had never really found on the internet, thank you!

Cool! I'm waiting for a colored E-ink monitor soon. I need it because I'm too sensitive to flickers and refresh rates.

You should really lean into the Inky Frame - would love to have an automated way of getting images there (would even be happy to film a build together)

I think the particles for the colored displays all have to have different masses because otherwise the particles would move horizontally symmetrically, as shown in the animation. I think the stacking algorithm would be, that at first it changes the charge so often that the particles with the highest mass are on the right spot and then it does the same procedure suczessively down to the particle with the lowest mass.

Good job.. Wish you showed more actual E-Ink displays vs just talking about them. But gives me a direction to google. Thanks.

Bit of an odd question, but do you know if there's any research into a translucent particle, rather than a pigmented particle? I've been curious about the idea for awhile, assuming the viscous liquid can act as a light piping layer, this would mean that a display could become emissive rather than reflective, and could work as both white plus translucency and black plus translucency based on application, or even color plus translucency. I know it's be a super niche application of e-paper tech, but there are some areas that could benefit from this, like use in poorly lit or dark rooms, and given that it's backlit and not an active display it'd be more efficient than an LCD or OLED display. Another thought I've had is about multi-color displays. Why are they forcing multiple colors into the same capsules and exponentially raising refresh times, or using filter layers that're subpar. Why not look into minimizing capsule sizes and mimic the RGB matrix that displays already use with a CMY matrix? Sacrifice particle per capsule density for capsule per display density.

I don’t know I’m afraid, E Ink keep their research very secretive.

using a cmy matrix would not work well and would cause the image to have awful saturation. it would be washed out if you used white pigment, and extremely dark if you used black pigment. subtractive color only really works if you are using the pigments to remove color from the light in series, but with a parallel grid, you would only be subtracting the R, G, or B color from 1/3 of the total R, G, or B value of the light.

5:03 But why couldn't they just use the colored particles (like you showed before) but with only one color per pixel?

That wouldn’t work with the additive color.

Assuming I'm not concerned with ghosting, what's the fasted refresh rate/fps for an e-ink device? Is basic animation possible? Also, why is there ghosting of what looks like brighter white on a white page? With your explanation of how the particles are arranged, I'd have thought it wouldn't be possible to get whiter than, well, white.

@megumin4625 Жыл бұрын

I have a boox device, and I can watch a youtube video with the heaviest ghosting mode. Maybe 5fps? I don't recommend ever doing it though. It's a horrible experience and not worth it

@ennisskalski719 Жыл бұрын

@@megumin4625 I was thinking from the position of it being an interesting medium for simple animation, even in black and white. 2D can get away with a lot, and depending on how the ghosting works, could even enhance the animation like a built-in smear/drybrush.

I have a question. How does the e ink displays change the color at a certain point? Is there a grid like capacitors where we change the polarity of the electric field? Also, does the electrodes on the top of the screen are transparent? If it is how can a metallic electrode can be transparent but not reflective since metals are usually reflect light? Thanks in advance :D

@GSephElec Жыл бұрын

Yes, there’s a grid of electrodes above and below the E Ink layer that forms the pixels. It’s the same as how an LCD works, using transparent electrodes. Search “ITO Electrodes” if you’re interested 😊

Hi, I have a question for you. I have a 7.5" waveshare e-paper with driver hat that worked fine. Now During the update it 'overshoots': it updates, shows the black fine, but then continues fading to light gray, and only then stops. I can't seem to figure out why.

Hey man, I'm having the exact same issue trying to display images on what I believe is the same display. It looks perfect, then turns kinda sepia on the last update. Did you ever find out the cause of this?

@The007dinosaur Жыл бұрын

@@RenoDeJong I think we figured out our issue partially. The room was too cold, warmed it up with a hairdryer and it worked way better. We think it's because the display needs to be in a different power state when it's cold but we're still working on it

How do they prevent the particles slowly loosing their charge?

I don’t know to be honest. I’ve seen theories that the voltages are applied as an AC signal, but I’m not sure.

Why use both black and white particles instead of just black particles and use the fluid they're suspended in be responsible for the white (or visa versa)? It would allow faster instant updates with 0 risk of colour ghosting or need for flashing. So why isn't this a thing?
