I recently received an order of 8x8 and 9x11 LED dot matrix displays from China. I am really interested in working with dot matrix parts that have square 'dots'. I also want the dots close together. Some time ago I ordered a few 5x7 parts from Futurlec. I liked these, but wanted something bigger. None of the normal retail electronics websites carried what I was looking for. I finally found them when I started looking at the websites, such as Alibaba, that listed manufacturers.
I contacted a few different companies. I usually asked them what was their sample policy, did they have parts with "square dots", and could they provide some spec sheets. I finally settled on two companies, one for 5x7 parts and one for 8x8 parts. After many more emails, I decided to order some samples.
Now I have to come up with something to do with them.
