Answer: Special type of screen technology
Notes: E Ink displays, like those found in Kindle e-readers, offer a paper-like reading experience with crisp screens. Originally developed at MIT in the 1990s, the technology is now owned by E Ink Corporation. The screens work by manipulating microcapsules filled with positively and negatively charged particles, creating text and images without the need for backlighting. This makes them ideal for prolonged reading, as they reflect light like paper and consume minimal power. Beyond e-readers, E Ink is utilized in bus stop displays, walking direction signs, and restaurant menu boards.
