Recently Jeri Elseworth completed a home-brew inverter - in silicon: http://hackaday.com/2010/03/10/jeri-makes-integrated-circuits/ It seems that making an LCD should be easy in comparison (though still harder than making a PCB): Reflective surface Polarizer Glass ITO coating (indium tin oxide - a translucent conductor) Liquid Crystal ITO coating Glass Polarizer Wire connections coming off exposed ITO on glass So the only two things I'm unsure about how to do right now: - How to get/make and work with ITO (mask glass with photoresist, expose to template, develop, coat with ITO, remove resist without removing ITO - or can you silkscreen/print/draw with ITO?) - How to get/make liquid crystal material Any ideas, pointers, or tips? Custom LCDs are cheap in large quantities, but not for short run and proof of concept projects. -- http://chiphacker.com/ - EE Q&A site -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
