Wrist-worn device with a variable-size display which is expanded by unrolling or sliding
This invention is a device with an expandable light-emitting display which is worn on a persons' wrist and/or lower arm. The expandable display can be a flexible display which can be rolled and then expanded by unrolling it out from a housing. In an example, the flexibility of the expandable second display can be adjusted. The second display can be made flexible so that is can be rolled around a roller, but can also be made rigid for use as a touch screen in an expanded state.
1. A wearable device with first and second light-emitting displays comprising:
a smart watch and/or wrist band which is configured to be worn around at least three-quarters of the circumference of a person's wrist and/or lower arm, wherein a dorsal portion of the smart watch and/or wrist band is configured to be worn on a dorsal quarter of the circumference of the person's wrist, wherein a ventral portion of the smart watch and/or wrist band is configured to be worn on at least part of the ventral quarter of the circumference of the person's wrist, wherein a first lateral portion of the smart watch and/or wrist band is configured to be worn on a first lateral quarter of the circumference of the person's wrist between the dorsal quarter and the ventral quarter, wherein a second lateral portion of the smart watch and/or wrist band is configured to be worn on a second lateral quarter of the circumference of the person's wrist between the dorsal quarter and the ventral quarter, wherein the second lateral quarter is opposite the first lateral quarter;
the first light-emitting display on the wearable smart watch and/or wrist band, wherein the portion of the smart watch and/or wrist band on which the greatest percentage of the first light-emitting display is located is the dorsal portion; and
the second light-emitting display on the wearable smart watch and/or wrist band, wherein the second light-emitting display has a first configuration in which the portion of the smart watch and/or wrist band on which the greatest percentage of the second light-emitting display is located is the first lateral portion or the second lateral portion and the second light-emitting display is a first size, wherein the second light-emitting display has a second configuration in which the portion of the smart watch and/or wrist band on which the greatest percentage of the second light-emitting display is located is the dorsal portion and the second light-emitting display is a second size, wherein the second size is greater than the first size, and wherein the second light-emitting display further comprises a plurality of flexibly-connected segments.
