Does each pixel in this picture consist of one color? Or, are there three colors (red, green, blue) in each pixel? If the latter is true, why does our abstraction of a raster display (next slide) assume that each pixel has a single color value?
This picture reminds me of instances where I take photos of certain types of computer screens with my smartphone and the screen often shows a pattern which is not visible by the naked eye. Why is that?
How do the gray pixels (e.g. the ones directly next to the darkest ones that make up the letters but are not fully black) influence our perception of the letters? Does it make a noticeable change in the line width when viewed from a regular distance on the display? I can see why it would make curved lines smoother but not straight lines, like the L.
Taking a closer look at the letters, it seems that beyond the darkest black pixels in the middle of the letters, there are also the less black/grayish pixels at the outer edge. Are there more to the diamond rules mentioned later in the lecture when it comes to rasterizing letters?
How many brightness levels are there for each LED? (Like, I'd imagine there to be 256 because RGB ranges from 0 to 255. But that seems like a lot.)
For extremely high resolution photos/videos (like high res TV screens), is it as simple as there are a lot of pixels or has there been a vast improvement in methods for representing colors?
I remember older monitors used to "create" colors by putting pixels with different colors next to each other. Is one set of red, green, and blue lights enough to display a single color, or do we still do things to a region of lights to make the color more realistic?
What impact do the different colored pixels on this slide have on how we see the text from farther away compared to if all of the pixels were black?
How would a high resolution device compare to this image? Is this an average photo of a "modern display"?
What will be the price difference if we replace all of the bulbs with the bulb that could display color directly?
For this example, the pixels appear to be more rectangles than squares. Is this true or is it just a matter of illusion? If true, what are the advantages of this?
