Abstract

An installation structure of electronic paper and a resistive film type touch panel, includes electronic paper, a resistive film type touch panel disposed on a back surface side of the electronic paper, and a multitude of protrusions that are disposed between the electronic paper and the resistive film type touch panel, and that are fixed to at least one of the electronic paper and the resistive film type touch panel.

Claims

1. An installation structure of a thin-type display and a resistive film type touch panel, comprising:

a paper-like thin-type display;

a resistive film type touch panel that is disposed on a back surface side of the thin-type display; and

a multitude of protrusions that are disposed between the thin-type display and the resistive film type touch panel and that are fixed to the resistive film type touch panel,

wherein the resistive film type touch panel includes a movable electrode film, and the multitude of protrusions are disposed on a surface of the moveable electrode film of the resistive film type touch panel,

wherein when a load is applied onto a front surface of the thin-type display, a protrusion locally pushes in the moveable electrode film of the resistive film type touch panel to form an input protrusion on a surface opposite to the surface, where the multitude of protrusions are disposed, of the moveable electrode film of the resistive film type touch panel, and

wherein the formed input protrusion makes a local input.

2. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1, wherein the multitude of protrusions are present more densely in a peripheral portion of the thin-type display and the resistive film type touch panel than in a central portion of the thin-type display and the resistive film type touch panel.

3. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1, wherein the multitude of protrusions are greater in height in a peripheral portion of the thin-type display and the resistive film type touch panel than in a central portion of the thin-type display and the resistive film type touch panel.

4. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1,

wherein the multitude of protrusions are provided by molding one surface of a flexible sheet, and

wherein a surface of the flexible sheet opposite to a protrusion surface is entirely bonded to the resistive film type touch panel.

5. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1,

wherein the multitude of protrusions are formed by an application and curing of a light-curable resin to one side of a flexible sheet, and

wherein a surface of the flexible sheet opposite to a projection formed surface is entirely bonded to the resistive film type touch panel.

6. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1, wherein the multitude of protrusions are formed by a direct application and curing of a light-curable resin to the resistive film type touch panel.

7. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1, wherein each protrusion of the multitude of protrusions has a dome-like shape.

8. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1, wherein each protrusion of the multitude of protrusions has a diameter of 1 to 2 mm and a height of 100 to 1000 μ

m, and an interval between adjacent protrusions of the multitude of protrusions falls within a range of 1 to 2 mm.

9. A resistive film type touch panel unit with front-surface protrusions to be used for the installation structure according to claim 1, comprising:

the resistive film type touch panel of the installation structure; and

the multitude of protrusions of the installation structure fixed on a front surface side of the resistive film type touch panel.

10. The installation structure of the thin-type display and the resistive film type touch panel according to claim 1,

wherein the movable electrode film includes a movable electrode formed on a lower surface thereof,

wherein the resistive film type touch panel includes a fixed electrode-supporting member including a fixed electrode formed on an upper surface thereof,

wherein the resistive film type touch panel includes a plurality of spacers,

wherein the movable electrode film and the fixed electrode-supporting member of the resistive film type touch panel are formed so as to face each other, and

wherein the movable electrode and the fixed electrode are formed so as to face each other, having the plurality of spacers interposed therebetween.
