INPUT APPARATUS AND DISPLAY SYSTEM
First Claim
1. An input apparatus comprising:
- a touch sensor including a transparent substrate with which an object is brought into contact, and a rectangular single sheet electrode formed on the transparent substrate from a transparent conductive film, to detect a contact point of the contacting object;
first detection means which inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a first direction, and takes out the measurement signal propagated through the rectangular single sheet electrode from another one of the two opposing perimeter portions, to detect the contact point along the first direction; and
second detection means which, after the contact point in the first direction is detected, inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a second direction intersecting the first direction, and takes out the measurement signal propagated through the rectangular single sheet electrode from another one of the two opposing perimeter portions, to detect the contact point along the second direction.

Abstract
An input apparatus includes: a transparent substrate with which an object is brought into contact; a rectangular single sheet electrode formed on the transparent substrate; first detection means which inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a first direction, and takes out the measurement signal from another one of the two opposing perimeter portions, to detect a contact point of the contacting object along the first direction; and second detection means which, after the contact point in the first direction is detected, inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a second direction, and takes out the measurement signal from another one of the two opposing perimeter portions, to detect the contact point along the second direction.

9. A display system comprising:
-
a display panel including a display unit; a transparent substrate which is disposed on a display side of the display panel and with which an object comes into contact; a rectangular single sheet electrode which is formed on the transparent substrate from a transparent conductive film; first detection means which inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a first direction, and takes out the measurement signal propagated through the rectangular single sheet electrode from another one of the two opposing perimeter portions, to detect a contact point of the contacting object along the first direction; and second detection means which, after the contact point in the first direction is detected, inputs a measurement signal to the rectangular single sheet electrode from one of two opposing perimeter portions along a second direction intersecting the first direction, and takes out the measurement signal propagated through the rectangular single sheet electrode from another one of the two opposing perimeter portions, to detect the contact point along the second direction. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
