Abstract

A portable information device includes: a first chassis member; a second chassis member foldably coupled to the first chassis member; a display provided across an inner surface of the first chassis member and an inner surface of the second chassis member, the display being foldable and a touch panel being stacked on the display; and a sheet member fixed to a back side of the display. The sheet member includes: a first layer portion provided with a plurality of holes at least in a part overlapping a bent portion of the display; and a second layer portion entirely covering the first layer portion, the second layer portion being made up of a conductor that is thinner than the first layer portion and having no hole at least in a location overlapping a wiring region of the touch panel.

First claim

1 . A portable information device comprising:
a first chassis member; a second chassis member foldably coupled to the first chassis member; a display across an inner surface of the first chassis member and an inner surface of the second chassis member, the display being foldable and a touch panel stacked on the display; and a sheet member fixed to a back side of the display, wherein the sheet member comprises:
a first layer portion having a plurality of holes at least in a part overlapping a bent portion of the display; and
a second layer portion entirely covering the first layer portion, the second layer portion being made of a conductor that is thinner than the first layer portion and having no hole in at least a location overlapping a wiring region of the touch panel.

2 . The portable information device according to claim 1 , wherein the plurality of holes are in the entire first layer portion.

3 . The portable information device according to claim 1 , wherein, in the sheet member, a top surface of the second layer portion is fixed to the back side of the display and the first layer portion is on a bottom surface side of the second layer portion.

4 . The portable information device according to claim 1 , wherein an inner diameter of each of the holes is 0.5 mm or smaller.

5 . The portable information device according to claim 1 , wherein the sheet member has a stacked structure of a first sheet that makes up the first layer portion and a second sheet that makes up the second layer portion.

6 . The portable information device according to claim 5 , wherein
the first sheet is a stainless steel sheet or an aluminum sheet, and the second sheet is a stainless steel sheet, an aluminum sheet, a copper sheet or a carbon sheet.

7 . The portable information device according to claim 1 , wherein the sheet member is made up of one sheet, one side of the one sheet having a plurality of recesses to serve as the first layer portion, and another side of the one sheet, which is a back side of the one side, serving as the second layer portion.

8 . A display assembly comprising:
a display that is foldable, a touch panel being stacked on the display; and a sheet member fixed to a back side of the display, wherein the sheet member comprises:
a first layer portion having a plurality of holes at least in a part overlapping a bent portion of the display; and
a second layer portion entirely covering the first layer portion, the second layer portion being made of a conductor that is thinner than the first layer portion and having no hole in at least a location overlapping a wiring region of the touch panel.

9 . The display assembly according to claim 8 , wherein the plurality of holes are in the entire first layer portion.

10 . The display assembly according to claim 8 , wherein, in the sheet member, a top surface of the second layer portion is fixed to the back side of the display and the first layer portion is on a bottom surface side of the second layer portion.

11 . A display assembly comprising:
a display that is foldable, a touch panel being stacked on the display; and a sheet member fixed to a back side of the display, wherein the sheet member includes a first layer portion having a plurality of holes in at least an entire part overlapping the display.
