Abstract
An electronic device has a structure in which two portions between which a bent portion of a display panel is positioned are each fixed to a housing. The electronic device takes two forms of a form in which the display panel is opened and a form in which the display panel is folded in three. The electronic device includes a mechanism for sliding two housings parallel to each other. The display panel is changed in shape so that a portion where a display surface of the display panel is convexly curved and a portion where the display surface of the display panel is concavely curved in the folded state move in directions parallel and opposite to each other. At this time, the two portions of the display panel which are supported by the housings are slid while their display surfaces maintain a state parallel to each other.
Claims13
An electronic device comprising:
- a display panel having flexibility, the display panel comprising a first portion, a second portion, and a third portion;
- a first housing comprising a first region and a second region;
- and
- a second housing,
- wherein the first portion is fixed to the first region of the first housing,
- wherein the second portion is fixed to the second housing,
- wherein the third portion is not fixed to the first housing or the second housing,
- wherein the display panel is configured to be folded and spread,
- wherein the display panel is configured such that when the display panel is spread, the third portion is positioned over the second region of the first housing and the third portion is positioned between the first portion and the second portion,
- wherein the display panel is configured such that when the display panel is folded, the third portion is positioned over the first region of the first housing and the second portion overlaps with the second region of the first housing without the third portion therebetween,
- wherein when the display panel is folded, the third portion comprises a first curved portion where part of a surface of the third portion is convexly curved and a second curved portion where another part of the surface is concavely curved,
- wherein the second curved portion is positioned on the first portion side and the first curved portion is positioned on the second portion side when the display panel is folded,
- wherein an area of the second portion is larger than that of the first portion, and
- wherein a curvature radius of the second curved portion is smaller than a curvature radius of the first curved portion.
An electronic device comprising:
- a display panel having flexibility, the display panel comprising a first portion, a second portion, and a third portion;
- a first housing comprising a first region and a second region;
- a second housing;
- and
- a mechanism for slidably connecting the first housing to the second housing,
- wherein the first portion is fixed to the first region of the first housing,
- wherein the second portion is fixed to the second housing,
- wherein the third portion is not fixed to the first housing or the second housing,
- wherein the third portion is configured to be folded and spread,
- wherein the display panel is configured such that when the display panel is spread, the third portion is positioned over the second region of the first housing and the third portion is positioned between the first portion and the second portion,
- wherein the display panel is configured such that when the display panel is folded, the third portion is positioned over the first region of the first housing and the second portion overlaps with the second region of the first housing without the third portion therebetween,
- wherein when the display panel is folded, the third portion comprises a first curved portion where part of a surface of the third portion is convexly curved and a second curved portion where another part of the surface is concavely curved, and
- wherein a curvature radius of the second curved portion is smaller than a curvature radius of the first curved portion.
