Benefits of technology

[0012]It is, therefore, an object of the present invention to provide a touch location detecting panel which has a simple layer structure and requires low manufacturing costs.
[0013]Another object of the present invention is to provide a touch location detecting panel which is able to avoid a reduced productivity caused by an increased number of connectors and complicate wiring by utilizing a limited number of channels of a touch detecting circuit in an economical way.Technical Solution

Problems solved by technology

Meanwhile, the discrete location detecting method has a limited touch location detecting resolution which is dependent on an arrangement pitch of sensing areas.
In this case, however, the lamination thickness of the touch location detecting panel increases, and manufacturing cost of the detecting panel is increased accordingly.
Unfortunately, however, the formation of the ITO pattern layers requires a costly process, and since the conventional touch location detecting panel has even two sensing layers 10 and 20 having such high manufacturing costs, total manufacturing cost is increased.

Abstract

A touch location detecting panel and, more particularly, a touch location detecting panel having a plurality of sensing areas arranged two-dimensionally. The touch location detecting panel has on a surface at one side of a single film, a plurality of sensing areas arranged two-dimensionally. Each of the sensing areas includes a plurality of partitioned areas electrically isolated from each other, and the partitioned areas are respectively connected to separate channels of circuit for detecting a user's touch on each of the partitioned areas. Accordingly, durability and productivity of the touch location detecting panel can be improved by simplifying the panel structure.

Description

TECHNICAL FIELD[0001]The present invention relates to a touch location detecting panel applicable to a touch location detecting device such as a touch pad or a touchscreen.BACKGROUND ART[0002]A touch location detecting device is a device for detecting a user's touch at a specific location on a panel that is installed overlappingly on a display screen or provided separately from the display screen. Information on the presence and location of a touch on the panel are utilized for the operation control, screen manipulation and the like of a computer system that incorporates therein the touch location detecting device.[0003]A method for detecting a touch location can be largely classified into two categories: a continuous location detecting type and a discrete location detecting type. The continuous location detecting method or an analog method measures a continuous change in, such as, optical or electrical characteristics caused by a change in user's touch location on a panel, and calc...
