I was wondering if these cheap digital photo displays could
render text, cost effectively, and I realised that I don't really
know how text is rendered on an LCD display.
I'm guessing, working from the display backwards:-
- How often is a non-changing display refreshed,
- So that's 4 * 48* 600 bits for a 16 colour VGA display ?
- What are typical resolutions for these 4 to 6 inch photo-displays?
- the line of text would be encoded char-by-char to H-lines of
- and then shifted into the 'dedicated LCD driver' ?
- is it fed in 8-bits wide or what ?
- what knd of signal do video DVD players output: analogue
- So you get: [char-line] -> [pixel-block] -> [display-driver]
Can someone point me to a good online tutor ?
