It is not a good idea to use just one current-limit resistor, as shown on that page:



You should not assume that current will be shared evenly between segments; even if it were so, this would mean that the display brighness would vary a lot depending upon the number of segments used!

LCD Tutorial and assembler help please            01/01/70 00:00      
   Understand meaning of EQU and DB            01/01/70 00:00      
      Wow didn't realize!            01/01/70 00:00      
         Your assembler manual...            01/01/70 00:00      
            ..thanks            01/01/70 00:00      
         Try understanding the LCD requirements, too!            01/01/70 00:00      
            I've played around with LCDs before            01/01/70 00:00      
               You can't avoid the study.            01/01/70 00:00

         Single resistor only ok with multiplexing            01/01/70 00:00      
            Multiplexing segments?            01/01/70 00:00      
               No, I don't think so            01/01/70 00:00      
               It was common in the days of LED-display calculators            01/01/70 00:00      
                  Technology moves forward            01/01/70 00:00      
                     Not much thought goes into some of those displays            01/01/70 00:00      
                        HP printers            01/01/70 00:00      
                           Good backlight on HPLJ too            01/01/70 00:00      
                           Yes, I've noticed that ... however ...            01/01/70 00:00
