The present invention relates to a touch panel and, more particularly, to a touch panel capable of improving electrical conductive characteristics of the touch panel, reducing the size of the touch panel, improving the visibility of the touch panel, and minimizing damage to a substrate when a failure test is performed on the touch panel.

Touch panel

The present invention relates to a touch panel and, more particularly, to a touch panel comprising: a substrate, which is divided into a valid area and an invalid area; sensing electrodes disposed in the valid area, thereby sensing a first input; touch electrodes disposed in the valid area so as not to overlap with the sensing electrode, thereby sensing a second input; first wirings disposed in the invalid area and connected to the sensing electrodes; and second wirings disposed in the invalid area and connected to the touch electrodes, wherein the touch electrodes are mesh form and disposed between the sensing electrodes, and each second wiring surrounds at least one sensing electrode and is electrically connected in a loop form.

A touch panel is provided with a power pattern. The touch panel may include a first substrate, a first pad and a second pad. The power pattern may be formed as the first substrate to surround an edge of one side of the substrate at least one or more times and not to be overlapped all the way from one end to the other end. The first pad may be electrically connected to one end of the power pattern. The second pad may be electrically connected to the other end of the power pattern. The touch panel may also include a second substrate for arranging a terminal unit electrically connected to the first pad and the second pad.

Touch panel using touch pen and formed with power pattern

The present invention relates to a touch panel having pen touch and electrode touch functions. Specifically, the present invention relates to a touch panel, which can enhance visibility of a view area and simplify the process of manufacturing the touch panel by improving wiring of sensing patterns for pen touch and arranging overlap structures, which are created as the sensing patterns cross each other, in a separate area other than the view area.

Touch panel for improving cross structure of sensing pattern

A touch panel of the present disclosure includes a substrate divided into a view area and an unavailable area. Sensing electrodes are formed in the view area to sense a first input, and touch electrodes are formed in the view area not to be overlapped with the sensing electrodes to sense a second input. A first wire is formed in the unavailable area to connect first ends of the touch electrodes, and second wires are formed in the unavailable area and connected to the second ends of the touch electrodes. A controller is connected to the second wires to control the touch electrodes, in which the first wire may be connected to the plurality of touch electrodes, and the second wires may connect each of the plurality of touch electrodes to the controller.

A digitizer includes a first substrate, a first electrode on the first substrate, a first insulating layer on the first electrode, and a second electrode on the first insulating layer. The first insulating layer is formed therein with a through hole to expose the first electrode, and the first and second electrodes make contact with each other through the through hole.

Touch device structure having through holes

Disclosed is a paste composition for printing including conductive powders, a binder, a dispersing agent, and a solvent. The dispersing agent includes a block copolymer of polyethylene oxide (PEO)-polypropylene oxide (PPO)-polyethylene oxide (PEO), or a block copolymer of polypropylene oxide (PPO)-polyethylene oxide (PEO)-polypropylene oxide (PPO).

Paste composition for printing and touch panel

A touch panel may have a pen touch and electrode touch function. More specifically, a touch panel may be capable of improving visibility of a view area and also simplifying a panel fabrication process by improving the wires of sensing patterns for a pen touch and disposing an overlap structure occurring between intersecting sensing patterns in a separate region other than a view area.
