Abstract
Keyboards and other electronic input devices have a key or keys with glyphs that are invisible to an unaided human eye in a first condition, such as when an underlying display attached to the key is not emitting light. The glyphs are visible through the key or keys when the display emits light. A one-way visibility layer or structure obscures the visibility of the display when viewed from above, but when the display emits light, the light penetrates through the one-way visibility layer, such as by passing through an array of microperforations in the key, and is visible to an onlooker.
