Embodiment Construction

[0035] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0036] figure 1 and figure 2 Respectively, an assembled perspective view and an exploded perspective view of the touch sensor according to the present invention.

[0037] Such as figure 1 and figure 2 As shown in , the touch sensor according to the present invention may include a base layer 100 , an electrode layer 200 , an insulating layer 300 , a bridge member 500 , a passivation layer 400 and the like.

[0038] The base layer 100 is a base supporting the electrode layer 200 etc. combined thereon. The base layer 100 may generally be a base film. When the touch sensor is manufactured by a transfer method, the base layer 100 may be a separation layer or the like.

[0039] The base film is not limited if it has good transparency, mechanical strength and thermal stability. Specific examples of the base film may include thermoplastic resins, for example, p...

Abstract

A touch sensor includes a base layer; an electrode layer including, on the base layer, first array sensing cells connected and arranged in a first direction and second array sensing cells spaced apart from the first array sensing cells and arranged spaced apart in a second direction, the first and second sensing cells being provided with dummy holes; an insulation layer formed on the electrode layer and being provided with contact holes connecting the neighboring second array sensing cells in the second direction; and bridges formed on the contact hole and the insulation layer to electrically connect the neighboring second array sensing cells.

Description

technical field [0001] The present invention relates to touch sensors. Specifically, in the upper connection method (top bridge) in which bridges are formed on the upper side, bridge regions can be visually recognized due to selective etching during bridge formation, and the present invention relates to the ability to prevent this. The touch sensor of the problem and its manufacturing method. Background technique [0002] Touch sensors in smartphones and the like are input devices that receive commands through touch. The touch sensor includes a resistive type, a capacitive type, an ultrasonic type, an infrared type, etc. according to a sensing method of a touch portion. Recently, capacitive types are mainly used for touch sensors. [0003] The capacitive type uses a transparent substrate on which a conductive thin film is formed. When a user touches the surface of the coated transparent substrate with a certain amount of current flowing through the surface of the transpa...
