Hmm, I'm not really sure. A monochrome pixel would be much more sensitive, but without a neutral density filter it might saturate when the RGB pixels are well-exposed. With a neutral density filter I think it could resolve better the variation of light intensities of very small features.
So, would the WWW be a monochrome LCD? Wouldn't these be similar to the ones sometimes used in small electronic displays like this one:
I am not sure of what the YWB would do.
I am also interested in the use of the 'E-Ink' displays for public signage in well-illuminated places. I found a few examples online:
I am not familiar with this... I looked it up and I think it is this? https://en.wikipedia.org/wiki/PenTile_matrix_family
I'll look into it. Interesting!
Large e-inks are unfortunately still quite expensive.
Yes, a WWW display is monochrome, tripling its light throughput. A YWB display is capable of color on the blue-yellow axis (although the color cannot be both bright and saturated) and has double the light throughput of RGB. What you're showing is a passive STN display, I'm after an active matrix (TFT or IPS). To save on driver development, there will still be subpixels, just without color – exactly the same as the normal RGB model except with clear gel instead of RGB for the color mask. Thanks to subpixel antialiasing that most OSs do by default, the extra horizontal resolution will not be wasted, at least with text.
BTW YWB's color gamut looks like this:
This might seem awful but remember that this is an extension of the YB color gamut (where the white component is 0) towards the top right (added white of course, which doubles the brightness of monochrome text):
If the factory can satisfy this, you can use any two colors (recommended saturated ones that add up to white):
As for the OLED, I mean this pattern:
Maybe this one is not Samsung's patent but either way, they sought to ban their patented pixel patterns' import to the US, effectively banning all but large-volume shipments of OLEDs (because the customs can't check for pixel patterns whenever a US repair shop orders a spare).
Some of these terms I am not yet familiar with, so I will need to do some reading. I'll save this comment and come back during the week. It seems like you are very knowledgeable about display technologies! Very cool
In short: (S)TN is almost always monochrome and in a calculator or Game Boy: just glass, electrodes and liquid crystal. It's cheap and customizable but it doesn't scale to high resolutions well and the contrast is poor. TFT (and the later IPS) is almost always color and uses a thin film transistor on each subpixel to hold its state between updates, simplifying driving while maintaining contrast at high resolutions.
