Abstract
The present invention generally relates to a touch panel including first electrodes, second electrodes, first signal wires connected to the first electrodes, and second signal wires connected to the second electrodes, two or more flexible printed circuit boards (FPCBs) being attached to one side of the touch panel to be spaced apart from each other by a distance which allows installation of an application component can be installed, and a display device including the same.
Claims14
A display device comprising:
- a touch panel comprising first electrodes, second electrodes, first signal wires connected to the first electrodes, and second signal wires connected to the second electrodes, wherein some of the first signal wires connected to the first electrodes are formed toward one side of the touch panel and other of the first signal wires are formed toward another side of the touch panel, or all of the first signal wires connected to the first electrodes are formed toward the one side of the touch panel, and the second signal wires connected to the second electrodes are formed toward the another side of the touch panel;
- two or more flexible printed circuit boards (FPCBs) attached to the one side of the touch panel and spaced apart from each other by a distance which allows installation of an application component, wherein each of the two or more FPCBs attached to the one side of the touch panel comprises first signal lines connected to all or some of the first signal wires through pads formed on the touch panel;
- one or more FPCBs attached to the another side of the touch panel, wherein the one or more FPCBs attached to the another side of the touch panel comprises second signal lines connected to the second signal wires through pads formed on the touch panel;
- additional pads for connecting the first signal lines formed on the two or more FPCBs attached to the one side of the touch panel;
- and
- connection lines connected between the additional pads,
- wherein when three or more FPCBs are attached to the one side of the touch panel, and numbers of the additional pads formed on each of the three or more FPCBs attached to the one side of the touch panel, respectively, are different from each other, the connection lines connected between the additional pads formed on the three or more FPCBs attached to the one side of the touch panel are formed in a same pattern.

A touch panel comprising:
- first electrodes and second electrodes formed as a touch sensor;
- first signal wires connected to the first electrodes and second signal wires connected to the second electrodes, wherein some of the first signal wires connected to the first electrodes are formed toward one side of the touch panel and other of the first signal wires are formed toward another side of the touch panel, or all of the first signal wires connected to the first electrodes are formed toward the one side of the touch panel, and the second signal wires connected to the second electrodes are formed toward the another side of the touch panel;
- attachment portions on the one side of the touch panel to which two or more FPCBs are attached to be spaced apart from each other so as to enable installation of an application component of the display device comprising the touch panel, wherein each of the two or more FPCBs comprises first signal lines connected to all or some of the first signal wires through pads formed on the touch panel;
- one or more attachment portions on the another side of the touch panel to which one or more FPCBs are attached, wherein the one or more FPCBs attached to the another side of the touch panel comprises second signal lines connected to the second signal wires through pads formed on the touch panel;
- additional pads for connecting the first signal lines formed on the two or more FPCBs attached to the one side of the touch panel;
- and connection lines connected between the additional pads,
- wherein when three or more FPCBs are attached to the one side of the touch panel, and numbers of the additional pads formed on each of the three or more FPCBs attached to the one side of the touch panel, respectively, are different from each other, the connection lines connected between the additional pads formed on the three or more FPCBs attached to the one side of the touch panel are formed in a same pattern.
