Large format e-paper touchscreen displays are unavailable or prohibitively expensive for consumer projects

Makers and developers need large touchscreen e-paper displays (>20 inches) for low-power applications like smart calendars and information displays, but the market offers almost no viable options. Current solutions are either tiny (under 10 inches), lack touchscreen capability, require high power consumption, or are industrial-grade products priced for enterprise use. This forces hobbyists and small project creators to abandon their ideas or use power-hungry LCD/LED alternatives that defeat the purpose of e-paper's efficiency.
