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 one of the thin-type display and the resistive film type touch panel.

2. The installation structure of a thin-type display and a 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 a thin-type display and a resistive film type touch panel according to claim 1, wherein

the multitude of protrusions are greater in height in the peripheral portion of the thin-type display and the resistive film type touch panel than in the central portion of the thin-type display and the resistive film type touch panel.

4. The installation structure of a thin-type display and a 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 a surface of the flexible sheet opposite to a protrusion surface is entirely bonded to one of the thin-type display and the resistive film type touch panel.

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

the multitude of protrusions are formed by application and curing of a light-curable resin to one side of a flexible sheet, and a surface of the flexible sheet opposite to a projection formed surface is entirely bonded to one of the thin-type display and the resistive film type touch panel.

6. The installation structure of a thin-type display and a resistive film type touch panel according to claim 1, wherein

the multitude of protrusions are formed by direct application and curing of a light-curable resin to one of the thin-type display and the resistive film type touch panel.

7. The installation structure of a thin-type display and a resistive film type touch panel according to claim 1, wherein

each of the multitude of protrusions is shaped dome-like.

8. The installation structure of a thin-type display and a resistive film type touch panel according to claim 1, wherein

each of the protrusions has a diameter of 1 to 2 mm and a height of 100 to 1000 μ

m, and an interval between adjacent ones of the 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; and

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

10. A thin-type display unit with back-surface protrusions to be used for the installation structure according to claim 1, comprising:

the thin-type display; and

the multitude of protrusions that are fixed on a back surface side of the thin-type display.
