An Ask HN post seeks recommendations for large-format, low-power touchscreen E-Paper displays exceeding 20 inches suitable for a calendar project. The discussion references a Hacker News thread with limited engagement, scoring 3 points and drawing no comments.
The original query emphasizes power efficiency and touch functionality, suggesting use cases beyond traditional e-readers. Large E-Paper panels remain niche, with few commercial options available above tablet sizes.
Users interested in similar projects may explore displays from vendors like Pervasive Displays or E Ink's evaluation kits, though most offerings top out around 13 inches. Custom solutions or industrial-grade panels from companies such as E Ink, Pervasive Displays, or Waveshare occasionally reach larger sizes but often lack integrated touch support.
For DIY enthusiasts, combining separate touch overlays with E-Paper screens presents one workaround, though responsiveness and clarity may suffer. The post reflects broader interest in ultra-low-power smart displays for home automation, calendars, or digital signage.
