True", I can give you lots and lots and lots of technical details about how to design a display well. But, as you know, when you get involved in display design, you can never do everything you want, right? So, the question is, where do you fight your battles and what do you say, "I give up, let them do it"? So, let's talk about that. Here's a list of parameters of displays, and the question is, what really matters a lot and what don't we care about? First, let's talk about wavelength, which refers to color. In old-time displays, you pretty much only got a monochrome image, but color does matter a lot. Also, the luminance of the display and the lumens contrast. However, the direction of contrast, whether it's black on white or white on black, doesn't matter very much, with a few exceptions. The exceptions, as Jake mentioned, have to do with night driving. When you're driving at night and you have black characters on a white background, the whole thing is lighting you up, which is not good for dark adaptation. You also get all kinds of reflections, so this is a bad idea. But, for any other conditions, it doesn't matter which direction the contrast goes. Someone made a comment about why readers have dark characters on a light background. Well, it's because people want it to look like a book. So, it looks more like a book if it's that way. For displays, there are a number of physical parameters that matter geometrically. And, for characters, the most important thing is the height. If it's tall enough and you get enough contrast, you're good. The width of the line also matters, but not as much as height. Now, let me talk about that more specifically by showing a...
