Description

TOUCH SCREEN PANEL AND METHOD OF MANUFACTURING THE SAME

The present invention relates to a touch screen panel and a method for manufacturing a touch screen panel, and more particularly, to a touch screen panel with improved visibility and a simplified manufacturing process, and a method for manufacturing a touch screen panel.

A touch screen panel is a device for recognizing a user's screen touch or gesture as input information, and is widely used by being installed in personal portable electronic devices such as smart phones and tablet PCs. A touch screen panel is mainly used by being disposed adjacent to a device for displaying an image, such as a display panel, and a user generally performs a touch input on an image displayed on the display panel.

A touch screen panel generally includes a touch sensing electrode for sensing a user's touch input. Recently, a mesh pattern made of a metal material having a low sheet resistance value and high flexibility has been used as a touch sensing electrode. A touch screen panel employing a touch sensing electrode formed in a metal mesh pattern has a structure in which a plurality of X-axis touch cells and a plurality of Y-axis touch cells having a mesh pattern are insulated by a separate insulating layer. That is, since a separate insulating layer interposed between the X-axis touch cell and the Y-axis touch cell must be formed in order to electrically insulate the X-axis touch cell and the Y-axis touch cell, an additional process for forming the insulating layer is required. The screen panel manufacturing process becomes complicated.

In addition, when the touch sensing electrode, that is, a plurality of X-axis touch cells and Y-axis touch cells having a mesh pattern are formed of a metal material, the plurality of X-axis touch cells and the plurality of X-axis touch cells are formed outside the touch screen panel due to the high reflectivity of the metal material A problem in which the Y-axis touch cell is visually recognized occurs.

On the other hand, when the display device is manufactured by bonding the separately manufactured touch screen panel to the display panel, the thickness of the display device due to a separate substrate used in manufacturing the touch screen panel increases, the manufacturing cost increases, and difficulties in the manufacturing process exists, and may not be advantageous in terms of design.

The second touch sensing electrode 140 is formed of a metal material. Referring to FIG. 2 , each of the plurality of second touch sensing electrodes 140 includes a plurality of line patterns 141 formed of a metal material. Since the second touch sensing electrode 140 is formed of a metal material, the second touch sensing electrode 140 is formed from the outside of the touch screen panel 100 due to the high reflectivity of the metal material constituting the second touch sensing electrode 140 .
