This is an interesting idea, but honestly it should be detachable and wireless. The refresh rate is so slow that there’s no reason to be wired and having an e-reader integrated into your display that you could pop off and keep reading would be amazing for comfort.
detachable and wireless.
Let me deepen this: there's no reason for eink to be attached to LED monitor at all. It's obviously more practical to have separate reader, all is needed is a possibilty to quickly share content to it.
Sounds like a second-gen product, or a premium option.
How many people are going to want to do this?
How many people are going to want to do this who wouldn't otherwise just buy an e-ink Android tablet that's got a display input that are already on the market?
Since e-ink tablets already understand PDF, the easiest way of doing this is to write a printer driver that picks a tablet as the target, and a daemon on the tablet that accepts the incoming PDF and makes it the new document being displayed.
Nook Simple touch is an android tablet with an eink screen (runs a custom rom but very easy to go stock android, though in time I found there was no benefit and went back to their custom rom).
I hope someone goes down this rabbit hole... is it possible to make a wireless e-paper display that does not need any battery? I am wary of batteries because I have managed to "swell up" two old android phones by keeping them constantly connected to power and using them to take timelapse videos.
proompt: can a supercapacitor power an e-ink display?
Google Bard:
Yes, a supercapacitor can power an e-ink display. E-ink displays are very low-power devices, so a supercapacitor can provide enough power to keep the display running for a long period of time. In fact, supercapacitors are often used to power e-ink displays in devices such as e-readers and wristwatches.
Supercapacitors are different from traditional capacitors in that they can store a lot of energy for their size. This makes them ideal for powering low-power devices, such as e-ink displays. Supercapacitors also have a long lifespan, which is important for devices that are used for extended periods of time.
If you are looking for a way to power an e-ink display, a supercapacitor is a good option. Supercapacitors are small, lightweight, and have a long lifespan. They are also very efficient at storing and releasing energy, which makes them ideal for powering low-power devices.
Here are some additional details about supercapacitors and e-ink displays:
* *Supercapacitors:* Supercapacitors are energy storage devices that can store a lot of energy for their size. They are made up of two electrodes separated by an electrolyte. When a voltage is applied to the electrodes, the electrolyte allows electrons to flow between them. This flow of electrons creates an electric field that stores energy.
* *E-ink displays:* E-ink displays are a type of electronic display that uses a layer of electrically charged microcapsules to create an image. The microcapsules are filled with a liquid crystal material that is either black or white. When an electric field is applied to the microcapsules, the liquid crystal molecules align in a way that either reflects or absorbs light. This creates the image on the display.
E-ink displays are very low-power devices because they do not require any backlighting. The only power that is needed is to create the electric field that aligns the liquid crystal molecules. This makes them ideal for powering with supercapacitors.

It's a niche product to begin with.
Since e-ink tablets already understand PDF, the easiest way of doing this is to write a printer driver that picks a tablet as the target, and a daemon on the tablet that accepts the incoming PDF and makes it the new document being displayed.
That would be perfect for my own use case actually.
I haven't heard of Android tablets with display in, got any links?

They don't support external video inputs though.
Very true, I totally missed that bit of the original comment.
Onyx Boox product range, there's likely others.
