What's funny about this is just how distorted the pixels are. Ever since I've understood what displays were (and CRTs before that) I've always imagined this idealized array of perfectly round, very tightly packed red green and blue circles as the pixels. Even looking close (not under a microscope) they look like a grid of squares... not these rectangular things with lots of space between them.
They seem to be getting more distorted over time. Maybe when they're so small its less of an issue. I'm surprised at how the red and blue on the kindle fire are so much bigger than the green. The eye is most sensitive to green... yet on the PSP Vita the blue seems to be the smallest of the pixels (meaning the blue pixels will have to put out more light to compensate, or the screen will have a green/red color cast.)
- smackfu 15y agoAre they really distorted though? I wonder if it's an artifact of trying to image a light source, maybe caused by the display not being perfectly level to the microscope stage. I ask because some of the images really do look perfect with sharp edges (the 3DS, the PSP), compared to the blobs of light you see on the other ones.
- LukasMathis 15y agoThe OpenPandora shot doesn't look sharp because it has an anti-glare coating. Some of the others may be a bit too bright for the cheap microscope I'm using, so they're a bit blurry. But mostly, the pixels really do look that way; most of them aren't rectangular at all.
- niels_olson 15y agoThanks for the pics! Since you have these devices and can simply count up the number of pixels and divide by the size of the display, would you please consider photoshopping in scale bars to reflect the length of some unit of measure?
- LukasMathis 15y agoThe pictures are less than 1mm wide. I've added a grey bar that approximates 1mm at the same scale at the top of the post to give a sense of the scale. Does that help?
- afterburner 15y agoGetting a lot of green I believe makes things look sharper. I got this from reading about Foveon image sensors.

- mortenjorck 15y agoWell... No, not really. Subpixel rendering takes advantage of the arrangement of component pixels, but not their shape.
