Problems solved by technology

Therefore, the intersection of the first connection pattern and the second connection pattern is easily damaged by static electricity.
[0009] As described above, when the intersection of the first connection pattern and the second connection pattern is damaged by static electricity, such as insulation breakdown or disconnection, it will cause poor drive of the touch panel.

Embodiment Construction

[0039] Hereinafter, with reference to the accompanying drawings, the embodiments of the present invention will be described in further detail.

[0040] figure 1 It is a plan view schematically illustrating an example of a touch panel.

[0041] Such as figure 1 As shown, the touch screen panel includes: a substrate 10; sensing electrodes 11 formed on the touch active area on the substrate 10; The pad portion 20 connects the sensing electrode 11 to an external drive circuit.

[0042] The touch active area overlaps with an image display area of ​​a display panel (not shown) disposed below the touch screen panel, so that the touch active area can be seen from the outside. The touch inactive area overlaps the non-display area, and cannot be seen from the outside due to a frame covering the non-display area or a light blocking layer that blocks light.

[0043] The substrate 10 may be a transparent substrate made of soft material.

[0044] The sensing electrodes 11 include: a pl...

Abstract

A touch screen panel according to the present invention includes: a substrate; a plurality of first sensing electrodes and a plurality of second sensing electrodes, wherein the first sensing electrodes are connected along a first direction on the substrate, and the second sensing electrodes are The sensing electrodes are arranged between the first sensing electrodes and connected along a second direction intersecting with the first direction; a plurality of first connection patterns and a plurality of second connection patterns, wherein the first connection The pattern connects the first sensing electrodes along the first direction, and the second connection pattern connects the second sensing electrodes along the second direction; the first insulating film is formed at least on the first Between a connection pattern and the second connection pattern; and a dummy pattern, formed in an island shape in a part of at least one of the first sensing electrode and the second sensing electrode, and electrically insulated from the sensing electrode to which it belongs .

Description

technical field [0001] Embodiments of the present invention relate to a touch screen panel, and more particularly, to a touch screen panel that can prevent poor driving caused by static electricity. Background technique [0002] The touch panel is an input device capable of inputting a user instruction by selecting instruction content displayed on a screen of an image display device or the like with a human finger or an object. [0003] For this, a touch screen panel is disposed on the front face of the image display device, thereby converting a contact position directly in contact with a hand or an object in a human body into an electric signal. As a result, the instruction content selected at the contact position is received as an input signal. [0004] Since the touch screen panel as described above can replace an additional input device connected to and operated on an image display device, such as a keyboard and a mouse, its use range is gradually expanding. [0005] T...
