Abstract

There is provided an operation detection apparatus including an operation detection layer, and a photocatalystic layer laminated on the operation detection layer. The photocatalystic layer has an ununiform amount of photocatalysts formed therein.

Claims (18)

1. An operation detection apparatus, comprising:

an operation detection layer; and

a photocatalystic layer laminated on the operation detection layer,

wherein the photocatalystic layer has an ununiform amount of photocatalysts formed therein,

wherein the amount of photocatalysts formed is based on an area on the photocatalystic layer for operation detection and an area on the photocatalystic layer for information display, and

wherein the photocatalystic layer have a concentration of the photocatalysts continuously changing along an edge traversing from the operation detection area toward the information display area.

2. The operation detection apparatus according to claim 1 , further comprising:

a display unit,

wherein the operation detection layer is laminated on a display surface of the display unit.

3. The operation detection apparatus according to claim 1 ,

wherein the operation detection layer includes an electrode configured to detect an electrical signal in the area for the operation detection.

4. The operation detection apparatus according to claim 1 ,

wherein the photocatalystic layer includes a first area and a second area, and

wherein an amount of photocatalysts per unit area is different in the first area and the second area.

5. The operation detection apparatus according to claim 4 , further comprising:

wherein the first area includes the area for the operation detection of the operation detection layer, and

wherein an amount of photocatalysts per unit are in the first area is smaller than an amount of photocatalysts per unit are in the second area.

6. The operation detection apparatus according to claim 1 , wherein the photocatalysts are made of Tungsten.
