In this episode Shahriar takes a look at an ultra-low power display technology. The Ynvisible Segment Display is an electrochromic display. It is categorized as a reflective display, meaning that it reflects ambient light instead of using a backlight. All layers are screen printed on a plastic substrate.
The display stack consists of organic layers including a plastic substrate, an electrochromic material, an electrolyte, and an electrode for each segment. Additional layers such as graphical overlays and circuits may be added if required.

In this episode Shahriar takes a look at some mailbag RF components. The set of Anritsu Bias-T blocks all have damaged DC paths. The teardown of the Bias-T shows its internal construction and assembly procedure. The SHF Bias-T offers a much more sophisticated and broadband response. A single Bias-T has survived with only a broken DC connector which is repaired and measured.
