Make my own 7 Segment Display
(1/6) > >>
PixieDust:
Hi,

I want to make a custom 7 segment display because I can't find one for sale that suits my needs. I spent a few hours scouring the net and came up with no results in terms of how to make one. Well there's people making massive ones, but I need to make a tiny one, the whole unit needs to be no more than 10mm in height. Any tips, suggestions, ideas?
phil from seattle:
I don't think you've looked hard enough.  I went on mouser and found several that were 10mm high or less.
PixieDust:
It's not the size that I can't find, it's the way the characters are displayed.
Ian.M:
If you really had to, you could mount a series chain of 0402 or even 0201 SMD LEDs for each segment on a custom double sided FR4 PCB to make the desired segment pattern for the required number of digits, then either laser cut or 3D print the face of the display from black ABS, with each segment as a void, and attach it to the PCB with translucent resin to fill each segment and diffuse the dots from the individual LEDs.   

It would be rather expensive and a total PITA to assemble . . . . .
Leo Bodnar:
It does not specify it should be LED so my solution would be to make custom LCD panel.  If you want it glow, use LED backlight.
I have made custom LCD panels (coincidentally, 7-segment displays in the shape and digit distance I wanted) in China and it is really easy.  Send them a drawing or sketch, approve their drawing, pay, then get half a dozen samples and go for production if OK.

P.S. I have been told there was a custom LCD video recently on eevblog
