Pin density options.
The number of dots per unit area currently used in a conventional display is limited by the space requirements of the powered actuators. The passive pins of current design can be made smaller without much increase in cost. A new prototype I have come across uses ten pins...
Thanks for the "schools of thought" compliment, but I feel unworthy....... Despite having held a strong interest in chemistry and physics over the last 20 odd years I have little in terms of formalised learning.
Thus I come cap in hand to the ex-sperts.
This is where I am looking for suitable...
There was a mechanical system using moving pins that was used back in the '80's, but that was basically a strip 1" x 6" and gave the braille version of letters only.
I envisage either pre coating at the manufacture of VDU (Visual Display Unit) in addition to the current coating (for colour) or...
I didn't see the movie...........unfortunately!!

From another site electropolymers and muscle wires (whatever they are) have been suggested.
To me the electropolymers sound the more hopeful but then I am unlearned.
I appologise if I have seemed overly cautious but I have nursed this idea for some years. Perhaps knowing the product will be more...
Thankyou Jabberwocky,

I appologise if I have seemed overly cautious but I have nursed this idea for some years. Perhaps knowing the product will be more helpfull.
The product I am looking to produce is a braille VDU...
Hi I am neither a chemist nor an engineer but.......
I have an idea that could help many disabled people.....
But!!!!!
I need to find a safe material that will "swell" when stimulated by electrons.
Can any one help, Please
Would piezoelectric ceramic or plastic do?
I,m not sure. Plastic...

I,m not sure. Plastic might, I was looking to use a form of membrane. The idea is not dissimilar to the coloured dots that coat the inside of a tv screen except the "swelling" rether than glowing.
