raster scan

Raster scanning is a method used by image displays, like computer monitors or TVs, to create images. It works by drawing the image line by line, starting from the top left corner, moving horizontally across each line, then down to the next line below, and repeating this pattern until the entire screen is filled. Think of it like reading a book: left to right, line by line. This systematic process allows the display to refresh and show a complete image efficiently. Raster scanning is fundamental to how most traditional screens render images smoothly and continuously.
