Abstract
Description
The present invention relates to a touch sensor and a manufacturing method thereof.
Nowadays, touch screens are mainly used for portable terminals such as mobile phones and PDAs. The touch sensors most commonly used in such a touch screen include a conductive film type, a resistive film type, an infrared matrix type, a capacitance change type, and a metal sensor fill type.
Particularly, a touch sensor of a capacitance change type forms a conductive film on a substrate, and when a voltage is applied, a high frequency spreads all over the conductive film, and when touching the screen with an object of a human hand or a conductor, It has a principle of detecting the high-frequency waveform due to the capacitance. Such a capacitive change type touch sensor has to touch using a hand or a conductor, so that it is easily exposed to a pollutant and the touch accuracy is lowered.
The present invention provides a touch sensor capable of improving touch feeling and restoring force and a manufacturing method thereof.
A touch sensor according to the present invention includes: a substrate formed in a plate shape; A metal layer formed on the substrate and having a touch pattern formed on a surface thereof; And an inner layer formed between the substrate and the metal layer and formed of polydimethylsiloxane (PDMS).
Further, the touch pattern may be formed in a wave form or a concavo-convex form.
In addition, the interval of the touch patterns may be 10-90 탆.
The touch pattern may be formed by heating the metal layer.
The touch pattern may be formed by pressing the metal layer.
The metal layer may be formed of gold or silver.
According to another aspect of the present invention, there is provided a method of manufacturing a touch sensor, comprising: preparing a substrate having a plate shape; An inner layer forming step of forming an inner layer formed of polydimethylsiloxane (PDMS) on the upper surface of the substrate; A metal layer forming step of forming a metal layer on the upper surface of the inner layer; And a touch pattern forming step of forming a touch pattern on the surface of the metal layer.
Further, in the touch pattern forming step, the touch pattern may be in a wave form or a concavo-convex form.
Further, in the touch pattern forming step, the metal layer may be heated to form the touch pattern.
Further, in the touch pattern forming step, the touch pattern can be formed by pressing the metal layer.
In the metal layer forming step, gold or silver may be deposited on the upper surface of the inner layer.
The touch sensor according to an embodiment of the present invention can improve touch feeling by forming a curved touch pattern on a metal layer.
In addition, the touch sensor according to an embodiment of the present invention includes an inner layer made of PDMS between a substrate and a metal layer, thereby improving touch feeling and restoring force.
