Cool 1px-Font that encodes letter-shape in RGB-Colors, which render in LCD-Subpixels.
Each pixel on your monitor is actually composed of three sub-pixels: one red, one green, and one blue. On an LCD monitor, subpixels are usually three thin strips in a row (though on some monitors, they may be three bars arranged vertically). […] I was thinking about this, and I decided to try something. I made [an] image. At 12x zoom, it looks like this, just a few innocent columns of pixels:
However, on a standard LCD monitor, if you look at it really closely, or with a magnifying glass or digital camera, you see this:
Every white pixel you see on a LCD-screen is rendered by 3 subpixels, Red, Green, and Blue. This is RGB. Each color has a fixed place in this line of 3 subpixels, Red to the left, then Green, Blue to the right. You can use these pixels to paint pictures (like, you know, any image you see on an LCD-Screen) or you can make tiny images that render as even tinier fonts.
For instance, we want to render a small 'o' in Subpixels, like so:
You can do this on an LCD-Screen with 1 white pixel, 1 pink pixel and another white pixel above each other. The white pixel is all Red, Green and Blue subpixels set, like ***, and a pink pixel is a combination of the Red und Blue subpixels at slot 1 and 3 and render like *[blank]*. Another white pixel (***) and you get your desired 'o' as shown above. And like this, that guy built a whole font. Nice!
