Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0046] Such as figure 2 As shown, in the touch panel of the capacitive coupling method, there is a method using the elastic insulating layer IE and the floating island-shaped electrode FE obtained by patterning the transparent film TF. This touch panel has a structure in which when inputting, the pen PN presses the transparent film TF to deform the elastic layer IE, thereby forming an electrostatic capacitance (Cx, Cy) formed by the floating island electrode FE and the X-Y electrodes (XE, YE). ) changes to detect the input coordinates. Furthermore, if image 3 As shown, the input operation can also be performed by pressing the transparent film TF with the finger FN.

[0047] In order to use such an elastic insulating layer, for example, an elastic material and a protective plate (film) satisfying the conditions shown below are required.

[0048] (elastic ma...

Abstract

The touch panel according to the present invention is a touch panel of a capacitive coupling type, having: a first substrate (XYES) on which a coordinate detecting electrode for detecting XY coordinates of a point is formed; and a second substrate (UP) provided so as to face the above described first substrate, wherein the above described second substrate (UP) is provided with an elastic layer (EL) having a rigidity lower than the above described second substrate and a conductive layer (CL), the above described elastic layer (EL) and the above described conductive layer (CL) are layered in this order towards the above described first substrate (XYES), a non-conductive spacer (SP) is provided between the coordinated detecting electrode and the conductive layer, and a space created by the spacer is filled in with a liquid (LQ).

Description

[0001] This application claims priority from Japanese Patent Application JP2010-237356 filed on October 22, 2010, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a touch panel, and in particular to a capacitively coupled touch panel, that is, a touch panel capable of performing input operations using a non-conductive pen or the like. Background technique [0003] In a display device (hereinafter referred to as a "touch panel") equipped with an input device, the input device has a screen for inputting information by touching the display screen with a user's finger or the like (contact pressing operation, hereinafter simply referred to as touch). For input functions, this display device is used in mobile electronic equipment such as PDAs and portable terminals, various home appliances, and stationary user guidance terminals such as unmanned reception machines. The drive method of this kind of touch pa...
