(Not even Apple ?!? Or at least some super-expensive, but still commercial (= non-experimental) displays ?) They exist, but it's limited to the high-end. E.g. Apple's XDR display has a 10-bit panel and FALD. Reference-class monitors are generally of the "dual film" type, which essentially means that the panel is two LCDs on top of each other, one being used to control only brightness of a given pixel, and the other for brightness and color. > (Though it's still not clear to me why more displays aren't using the standard (at least in Charge Coupled Devices) 2x2 Bayer Filter with double green, rather than a 3x1 one ? Too much reliance on Windows' ClearType hack working properly ? But why in TVs too ??) Non-standard pixel layouts are common in OLEDs, e.g. RGBW, weird pyramids and un-even subpixel sizes (I'm assuming due to differing phosphor efficiencies). These all lead to poor text and UI clarity, as one would expect. (It's worth pointing out that OLEDs, being LEDs at their heart, have inherently lacking linearity which is why most of their brightness range is covered by digital modulation) RGB subpixels require the fewest number of subpixels, which also means reduced brightness loss due to LCD structures. Going to Bayer would mean 33 % more pixels for the same display, except it's dimmer (increasing pixel pitch by 50 % horizontally does not make up for halving it vertically), more expensive to make and also dimmer because now you have two green dots per pixel, so they need to be half as bright, throwing away more of the backlight, and the drivers now need to perform with inhomogenous pixels -- without an obvious upside. The reason color camera sensors tend to use Bayer filters is - I think - because green contributes most to perceived brightness, so doubling the sensor area for green means halving green's contribution to luma noise. This problem does not exist in displays.
