I have to admit I am finding some of this rather indigestible. Television has certainly 'moved on'.
Panrock: But if one were to do the same with a modern digital display panel - or say a mobile phone - what would one see?
This seems to be a question impossible to answer, since it depends so much on the display technology!
Frank.C: The vertical blanking lines referred to above I would assume are to accommodate CRT TV's. In a digital system it would appear to be wasteful to transmit them.
Just as in mechanical systems, like my 120-line mirror screw. At the end of one line (or frame), it's merrily straight on with the next, with no gap whatsoever.
Mike Watterson: There are very many display technologies now. Most will use a block of RAM for a frame...
So (in general) there are still frames then? I presume these will be rendered progressively. How many per second? Quite a lot, I guess, because with the many display technologies, you can't rely on 'phosphor lag'.
Though scanned frames as such may no longer exist. Rather, the 'frame rate' may simply signify how often this-block-or-that is reviewed for a change in picture content. I have an awful feeling that even asking a question like this may show I've lost the plot.
