Abstract
Particular embodiments described herein provide a display that includes a mask that includes a one or more exposed areas, a top electrode, one or more bottom electrodes, a dielectric between the top electrode and the one or more bottom electrodes, and an electrical connection to create a differential voltage between the top electrode and the one or more bottom electrodes.
Claims18
A bi-stable display in a keycap of a key, the bi-stable display comprising:
- a mask that includes a one or more exposed areas;
- a top electrode;
- one or more bottom electrodes;
- a dielectric between the top electrode and the one or more bottom electrodes, wherein the dielectric changes from one state to another state when a differential voltage is applied between the top electrode and the one or more bottom electrodes;
- and
- an electrical connection to create the differential voltage between the top electrode and the one or more bottom electrodes, wherein the bi-stable display is above a dome of the key.
3 more elements
A method comprising:
- creating a bi-stable display in a keycap of a key, wherein the bi-stable display includes:
- a mask that includes a one or more exposed areas;
- a top electrode;
- one or more bottom electrodes;
- a dielectric between the top electrode and the one or more bottom electrodes, wherein the dielectric changes from one state to another state when a differential voltage is applied between the top electrode and the one or more bottom electrodes;
- and
- an electrical connection to create the differential voltage between the top electrode and the one or more bottom electrodes, wherein the bi-stable display is above a dome of the key.
4 more elements
An electronic device, comprising:
- a first housing, wherein the first housing includes a keyboard, wherein the keyboard includes a plurality of keys and each of the plurality of keys includes a keycap above a dome, wherein each of the plurality of keys includes a bi-stable display in the keycap above the dome, wherein the bi-stable display includes:
- a mask that includes a one or more exposed areas;
- a top electrode;
- one or more bottom electrodes;
- a dielectric between the top electrode and the one or more bottom electrodes, wherein the dielectric changes from one state to another state when a differential voltage is applied between the top electrode and the one or more bottom electrodes;
- and
- an electrical connection to create the differential voltage between the top electrode and the one or more bottom electrodes, wherein the display is above the dome of the key.
