character representations

"but only few representations are unambiguous and intuitive at the same time: uppercase A, B, C, E, F, G, H, I, J, L, O, P, S, U, Y, Z, and lowercase a, b, c, d, g, h, i, n,o, q, r, t, u"

Does anyone have a source for this claim along with a list of which representation for each is considered unique and intuitive?

Elevators

Are there any elevators with seven-segment displays? --84.61.165.65 (talk) 15:08, 18 January 2010 (UTC)[reply]

Why would anyone delete the hexadecimal encoding from A-G??

I really want to know what he/she was thinking. I would add them by myself but it seemed hard to understand managing tables. 78.181.36.202 (talk) 02:09, 30 April 2010 (UTC)[reply]

how much current needed for seven segment 5"?

anybody knows? —Preceding unsigned comment added by 125.164.215.198 (talk • contribs)

For LED 7 segement displays the manufacturers datasheets will give you maximum continuous and peak currents. Typically large displays have multiple LEDs per segment and have them in series (or for the really big displays a combination of series and paralell) so will need much higher drive voltages than smaller displays. Watch out for the decimal point as it will often have much lower ratings than the rest of the segments.

LCDs are more complex requiring an AC drive, once again you need to read the manufacturers datasheet. Plugwash (talk) 12:39, 1 September 2010 (UTC)[reply]
