Hi,
I am trying to design a 7-segment display (manual binary switch controlled) something similar to the one found on this site, however I need the display to be larger than the average 7-segment display chip. I was wondering if the display could be made of 5-6 LED's per segment to create a single digit. The resulting number of LEDs would be around 39 per digit, thus making a four digit display approximately 3.5" high, and 5.5" wide. I have been out of the electronics field for awhile and need help with chip identification and specs. The current would be significant compared to the conventional 7-segment display chip. I am thinking of powering the circuit with a 6Vdc or 12Vdc supply. I was thinking of the circuit shown on this site, but I don't think there would be enough current to drive the amount of LED's per segment to make them bright enough to see.
any suggestions are welcome. This circuit is for personal use only.
Thank you,
