I think your phrase "with subpixels" directly contradicts "exceedingly crisp squares". I'm actually somewhat curious what you think a subpixel is, if you think it can combine into an exceedingly crisp square. For instance, this is the Nexus One screen under a microscope: https://commons.wikimedia.org/wiki/File:Nexus_one_screen_microscope.jpg https://commons.wikimedia.org/wiki/File:Nexus_one_screen_mic... Each of those lights is a subpixel. The bottom half of this image shows some other common LCD pixel layouts: https://commons.wikimedia.org/wiki/File:Pixel_geometry_01_Pengo.jpg https://commons.wikimedia.org/wiki/File:Pixel_geometry_01_Pe... As you can see, subpixels can be square but usually aren't, and pixels can't be square because they're made of subpixels. Out of curiosity, I took a picture of my monitor, and this is what it looks like: https://i.imgur.com/Ce7186v.jpg https://i.imgur.com/Ce7186v.jpg These look very different from the microscope pictures because the light sources are "glowing", which I think is probably more accurate to how we actually perceive pixels. But as you can see, "glowing" makes them not square, but round!

The most common modern geometry is the fourth one ("LCD") in your second link, where each pixel is indeed perfectly square. That's what I was referring to. The fact it is made of three rectangular subpixels in no way means "pixels can't be square". And the "glowing" effect in your picture is an artifact of light bleed from your camera. The only time we perceive pixels as round rather than square is if we have eyesight problems that blur the image projected onto our retina.

  I mean, with the fourth one, each pixel is only approximately square when white. A red, blue, or green pixel would be very rectangular. That's what I mean. Because of the way subpixels combine into pixels, only some colors can be square.

The RGB subpixels of your monitor would be more apparent if you had a higher magnification. Compared to what I see under my jewelers loupes, the first image you posted looks close to my screen under 90x magnification. They display different levels of RGB to show different colors.
