  Why not RGBW with some interesting wavelength response of the white subpixel?

  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.

  Same with LCDs. It wouldn’t take much change in the manufacturing process much to create a WWW or YWB 1080p LCD that has less or no color but passes way more light, allowing less backlight or even a reflective mode, while still being driven with conventional electronics

  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.

  These could be used in public transport signage etc. In some cases, a monochrome LCD with RGB backlight could also come in handy.

  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:

  Also not really related but it infuriates me that Samsung turned the Bayer filter 45°, halved the pixel count and patented it as an OLED pattern so nobody can make similar displays.

  I am not familiar with this… I looked it up and I think it is this? en.wikipedia.org/wiki/PenTile_matrix_family

  I’ll look into it. Interesting!

    Yes, a WWW display is monochrome, tripling its light throughput. A YWB display is capable of color on the blue-yellow axis 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.

    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: STN 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 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.
