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

[0040] Hereinafter, the embodiments of the present invention will be described in further detail with reference to the drawings.

[0041] figure 1 It is a plan view schematically illustrating an example of a touch screen panel.

[0042] Such as figure 1 As shown, the touch screen panel includes: a substrate 10; sensing electrodes 11, which are formed on the touch active area of ​​the substrate 10; and a peripheral cable 21, which is formed in the touch inactive area at the periphery of the touch active area, so as to pass The pad portion 20 connects the sensing electrode 11 to an external driving circuit.

[0043] The touch active area overlaps with an image display area of ​​a display panel (not shown) arranged at the lower part of the touch screen panel, so that the touch active area can be seen 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....

Abstract

A touch screen panel includes a plurality of first sensing electrodes on a substrate, the plurality of first sensing electrodes being connected to each other in a first direction, a plurality of second sensing electrodes between the first sensing electrodes on the substrate, the plurality of second sensing electrodes being connected to each other in a second direction intersecting the first direction, a plurality of first connecting patterns connecting the first sensing electrodes to each other in the first direction, a plurality of second connecting patterns connecting the second sensing electrodes to each other in the second direction, a first insulating layer at least between the first connecting patterns and the second connecting patterns, and dummy patterns in at least one of the first and second sensing electrodes, the dummy patterns having island-shapes and being insulated from the first and second sensing electrodes.

Description

Technical field [0001] The embodiments of the present invention relate to a touch screen panel, and more particularly, to a touch screen panel that can prevent driving failures caused by static electricity. Background technique [0002] A touch screen panel is an input device that can use a human finger or an object to select instruction content displayed on a screen of an image display device or the like to input user instructions. [0003] To this end, a touch screen panel is provided on the front face of the image display device, thereby converting the contact position directly in contact with the hand or object in the human body into an electric signal. Thus, the selected instruction content at the contact position is received as an input signal. [0004] Since the touch screen panel as described above can replace additional input devices, such as a keyboard and a mouse, which are connected to and run on the image display device, its use range is gradually expanding. [0005] The...
