Abstract

A display apparatus includes a flexible display part expressing images, a housing accommodating the display part, the display part being drawn into and out of the housing, a revolving part in the housing, the display part being wound on the revolving part in a predetermined rotation direction, a fixing part in the housing, the fixing part securing the display part when fully spread out, and a pressing part connected to an interior of the housing, the pressing part pressing the fixing part toward the revolving part.

First claim

What is claimed is:

1 . A display apparatus, comprising:
a flexible display part expressing images; a housing accommodating the display part, the display part being drawn into and out of the housing; a revolving part in the housing, the display part being wound on the revolving part in a predetermined rotation direction; a fixing part in the housing, the fixing part securing the display part when fully spread out; and a pressing part connected to an interior of the housing, the pressing part pressing the fixing part toward the revolving part.

2 . The display apparatus according as claimed in claim 1 , further comprising a grip connected to the display part, wherein:
the display part includes a long side extending along a first direction, and a short side extending along a second direction, a first side of the display part is connected to the housing in the first direction, and a second side of the display part is connected to the grip in the first direction.

3 . The display apparatus according as claimed in claim 2 , wherein the housing includes an opening, the display part being drawn into and out of the opening.

4 . The display apparatus according as claimed in claim 3 , wherein the housing further comprises:
an upper housing; and a lower housing connected with a bottom of the upper housing, the opening being in a lateral side of the upper housing and extending in the second direction.

5 . The display apparatus according as claimed in claim 4 , wherein the grip is longer than the opening in the second direction.

6 . The display apparatus according as claimed in claim 5 , wherein the revolving part includes:
a roll shaped as a cylinder extending in the second direction, the display part being wound on an outer surface of the roll; and an axis penetrating the roll in the second direction, opposite edges of the axis in the second direction being fixed to an inner surface of the housing, and the roll revolving in a predetermined direction around the axis.

7 . The display apparatus according as claimed in claim 6 , wherein the fixing part includes:
a holding rod extending in the second direction and holding the display part; first and second protrusions directly contacting an outer periphery of the revolving part, the protrusions being spaced apart from each other along the second direction; and first and second supports connecting the first and second protrusions to respective edges of the holding rod, centers of the first and second supports being connected to the housing, and the holding rod moving in accordance with a seesaw mechanism complementarily with the first and second protrusions.

8 . The display apparatus according as claimed in claim 7 , wherein:
the roll includes first and second rails on an outer periphery of the roll at opposite ends in the second direction, the first and second rails progress in spirals in the second direction while the roll is revolving, and the display part is wound on the outer periphery of the roll between the first and second rails.

9 . The display apparatus according as claimed in claim 8 , wherein the first and second rails include intaglios, the first and second protrusions being engaged with the first and second rails, respectively, and the first and second protrusions progress in the second direction along the spirals while the roll is revolving.

10 . The display apparatus according as claimed in claim 9 , wherein:
a depth of the intaglio decreases as the display part is spread out, the first and second protrusions ascend as the roll is revolving in a direction of spreading the display part, and the holding rod descends and presses down the display part in correspondence with the ascended first and second protrusions.

11 . The display apparatus according as claimed in claim 10 , wherein the spirals of the first and second rails are longer than the long side of the display part in the first direction.

12 . The display apparatus according as claimed in claim 11 , further comprising a plurality of elastic members, each elastic member including at least one springs, wherein:
the first and second pressing parts are connected with an interior of the upper housing via the elastic members, a bottom surface of the first pressing part contacts a top surface of the first protrusion, and a bottom surface of the second pressing part contacts a top surface of the second protrusion, and the first pressing part presses the first protrusion downwardly, while the second pressing part presses the second protrusion downwardly.

13 . The display apparatus according as claimed in claim 12 , wherein the first and second pressing parts correspond respectively to the first and second rails by length in the second direction.

14 . The display apparatus according as claimed in claim 6 , wherein the roll includes:
a circuit sheet to output image signals; an elastic circuit sheet to connect the circuit sheet with the display part; and a drive IC on the elastic circuit sheet, the drive IC converting the image signals, which are supplied from the circuit sheet, into drive signals to activate the display part.

15 . The display apparatus according as claimed in claim 8 , further comprising a lockup member adjacent to the first and second rails, the lock up member affixing the first and second protrusions.

16 . The display apparatus according as claimed in claim 15 , wherein the lockup member has a bottom end movable in the second direction to overlap the first and second rails, the lockup member blocking movement of the first and second protrusions along the first and second rails.

17 . The display apparatus according as claimed in claim 16 , wherein the lockup member is L-shaped.

18 . The display apparatus according as claimed in claim 7 , wherein the holding rod is curved in the second direction.

19 . The display apparatus according as claimed in claim 18 , wherein the grip and opening are curved in the second direction.
