I want to control 32x32 (or even 64x64) pieces of electroluminescent or electrochromic film with a microcontroller. Film itself will be driven by supertex hv816. Planned refresh frequency 2-4Hz.
There are two variants:
- simple, where piece has only two states, turned off and turned on
- more complex where there are some intermediate states
For the first variant I think I can use shift registers, and digitally controlled pots for the second variant.
Is it possible to control this drivers using matrix approach? I hope there is way better then one output-one piece of film implementation.
