Hehe grappig. Die mega array kan je gewoon vergelijken als bitmaps?
Edit:
Hehe, ik ging ook ff een tekentje creëren:
124=> array("00000","00000","01010","10101","10001","01010","00100","00000")
Kun je hartjes doen met '|'

Zie: http://www.asciitable.com/ voor een overzicht van de ASCI waardes (van alle tekens, inclusief de kleine letters) Misschien wel handig..
een overzicht van die tekens vind je hier : http://www.htvision.com/DOWNLOAD/HD44780.PDF (pag 18)
Elk karakter telt 5x8 dots. dus 8 rijen van 5 pixels. Eigenlijk is het maar 5x7 pixels, de laatste rij wordt gebruikt voor de cursor, maar kan eventueel ook meegenomen worden in de fontset.
Zoals Gerben eerder al aangaf :
124=> array("00000","00000","01010","10101","10001","01010","00100","00000")

Vandaar dat ik maar enkel de hoofdletters toegevoegd heb. :)
Classe ziet er goed uit, zal m straks eens proberen.

Als je de $chars-array static maakt, hoeft PHP die niet bij iedere instantie van de klasse aan te maken maar deelt hij gewoon 1 setje arrays. Dat scheelt weer wat uitvoertijd en geheugen.
... al kan ik zo geen toepassing verzinnen van meerdere van deze dingen op 1 pagina. Wat je wel nog zou kunnen doen is naast de display-method ook nog een export-method aanmaken die het ding opslaat als een bestand. Dan verplaats je de teken-logica naar een protected method genaamd render of draw ofzo.
En misschien dat je de kleuren etc ook nog variabel kan maken. Die zijn nu hardcoded in de klasse.

Voor Tommy: Dit is gewoon met een refresh. Met AJAX is het vast veel mooier.
