Led lighting project for displaying unicode characters.

[Prashantakerkar]

Is it possible to display unicode characters / Symbols with Led?.

Examples : Copyright symbol, @, #, £ etc

If yes, How?.
If no, why?.

Or is it some unicode characters can be displayed but not all ?

Thanks & Regards,

Hi,

"unicode" is just the code scheme for a string. It is related to a programming language (and data storage)
But it is not related to a display.

The display datasheet should tell you what characters it can show.
With some displays you can define your own characters.

Thanks.

I mean similar to digits 0 to 9 & 26 alphabetic characters, Can the Unicode characters be displayed using 7 / 9 / 14 etc segment Led display ?

Examples : £ , @, # , °, ®, ¢ etc

Thanks & Regards,

Hi,

Again:

The display datasheet should tell you what characters it can show.

--> Read the datasheet.

You can try on your own, how "£ , @, # , °, ®, ¢ " should look on a 7 segment display.

Do an internet search for unicode. You will find out that there are more than 1million possible characters.
A 7 segmant is able to show 127 different combinations - not all may be recognized as valid characters.

Thanks.

Whether a 14 or 16 segment Led display can display all unicode characters are to be traced.

Hi,

Please do a little research, datasheet reading and testing on your own.

Hi,

LED matrix that's what they use for all that stuff, not 7-segment displays.

You can map the most complex and/or largest unicode or whatever language character onto a piece of graph paper - really high tech stuff. When you know how many maximum squares are filled by a character in the vertical and the horizontal planes, you can count how many LEDs you will need to make a square, rectangle or circle or any shape in fact LED matrix.

Think London, New York, Mumbai, Tokyo, anywhere with huge LED advertising matrixes/screens, or modern bus numbers and destinations, or airports and train stations - they all use (LED) matrixes of small and building-size dimensions.
