The force direction and the touch pressure controller unit 700 detect the touch pressure by a capacitance change between the first electrode member 70 and the second electrode member 80. [

The present invention has a constant capacitance change value due to the elastic change of the nanofiber member between the first electrode member 70 and the second electrode member 80, The pressure controller unit 700 can perform a multistage object by defining a multistage interval using an electrical change value corresponding to a pressure externally applied, that is, a capacitance change value.

The force direction and the touch pressure controller unit 700 measure the resistance value of the current flowing through the first electrode member 70 and the second electrode member 80 and change the touch pressure One example is detection.

When the first base material 10 is pressed by the user's touch, the first base material 10 is bent by the pressure, and the first electrode material 70 and the conductive powder 31a So that the resistance value of the current flowing through the first electrode member 70 and the second electrode member 80 is reduced.

This is because the distance between the first electrode member 70 and the second electrode member 80 is small and the distance between the first electrode member 70 and the conductive powder 31a distributed on the nanofiber member The resistance value of the current flowing through the first electrode member 70 and the second electrode member 80 becomes smaller due to the increase of the contact area, and the current flows more smoothly.

When the pressure at which the first substrate 10 is pressed is increased, the distance between the first electrode member 70 and the second electrode member 80 becomes smaller, and the distance between the first electrode member 70 and the first electrode member 70 The area of contact with the conductive powder 31a distributed on the nanofiber member is further increased so that the resistance value of the current flowing through the first electrode member 70 and the second electrode member 80 becomes smaller, More smoothly flows.

That is, when the first substrate 10 is pressed by the user's touch, the force direction sensor unit 500 or the touch pressure sensor unit 600 may contact the first electrode member 70, The first electrode member 70 and the second electrode member 70 are formed by the change in the interval between the second electrode members 80 and the change in the contact area between the first electrode member 70 and the conductive powder 31a 80 to sense the touch pressure.

The force direction sensor unit 500 may be configured such that when the user touches the cover base material 300, the elastic membrane member 30 is pressed by the force generated in the X axis direction or the Y axis direction on the plane of the cover base material 300 The first electrode member 70 and the second electrode member 80 are compressed to generate a difference in capacitance value or current resistance value between the first electrode member 70 and the second electrode member 80 and are received by the force direction and the touch pressure controller unit 700, The touch pressure sensor unit 600 is compressed by a force generated in the Z axis direction on the plane of the cover base material 300 when a user touches the cover base material 300 and the elastic membrane member 30 is compressed A difference in capacitance value or a difference in resistance value between the first electrode member 70 and the second electrode member 80 is generated and the force direction and the touch pressure controller unit 700 receive the operating principle Can be the same Place revealed.

The force direction sensor unit 500 may be the same as the pressure sensor unit 600 in that the pressure sensor unit 500 is a pressure sensor that is operated while being compressed by a force that the user pushes or pulls the cover substrate 300 do.

The force direction and the touch pressure controller unit 700 may divide the difference in capacitance between the first electrode member 70 and the second electrode member 80 in the touch pressure sensor unit 600, A step of dividing the resistance value difference of the current flowing through the first electrode member 70 and the second electrode member 80 by a section and dividing the multi-step section with respect to the pressure in the plane Z axis direction on the cover base material 300 And to perform multi-level object (Object).

In addition, the force direction and the touch pressure controller unit 700 may be configured such that the force direction sensor unit 500 disposed at the outer circumference of the cover substrate 300 is in contact with the first electrode member The change in the capacitance of the second electrode member 80 or the change in resistance of the current flowing through the first electrode member 70 and the second electrode member 80, Axis direction on the plane of the cover base material 300 and divides the direction of the force with respect to the pressure in the Z-axis direction on the plane of the cover base material 300 along with the multi- So that more multi-level objects can be distinguished and performed.

When the distance between the first electrode member 70 and the second electrode member 80 is changed and the first electrode member 70 and the second electrode member 80 are elastically deformed by the touch pressure, The resistance value of the capacitance or the current between the members 80 is changed and the force direction and the touch pressure controller unit 700 are changed between the first electrode member 70 and the second electrode member 80 And a plurality of pressure intensity modes which are divided into a change in capacitance or a multistage interval of the touch pressure divided by a difference in resistance value of a current flowing between the first electrode member (70) and the second electrode member (80) , And when a touch pressure corresponding to the pressure intensity mode is applied, a multi-step object for the touch pressure can be performed.

In addition, the force direction and the touch pressure controller unit 700 may include the first electrode member 70, the conductive powder in the nanofiber member, and the second electrode member 80 when the nanofiber member shrinks by a predetermined degree or more. And a conductive path is formed between the first electrode and the second electrode so that an Off => On operation, that is, an object for a short mode can be performed.

The short mode is a mode in which a conductive path made of the first electrode member 70, the conductive powder in the nanofiber member, and the second electrode member 80 is generated, and a plurality of It has one of the most reliable modes compared to the pressure intensity mode.

Accordingly, when the number of steps for multi-stage object performance classified by the touch pressure is determined, the plurality of different pressure intensity modes can be divided into a wider range.

For example, in the case where the multi-stage object performance is divided into four without the short mode, the electrostatic capacitance change range between the first electrode member 70 and the second electrode member 80, or between the first electrode member 70 and the second electrode member 80, The resistance value difference range of the current flowing through the two-electrode member 80 is divided into four ranges and each object is performed. Therefore, the user can finely perform the accurate object operation only by finely dividing the pressure.

On the other hand, in the present invention, when the multistage object performance classified by the touch pressure is divided into four, the short mode clearly distinguishably performs one object, and the first electrode member 70, And the second electrode member 80 or a resistance value difference range of the current flowing between the first electrode member 70 and the second electrode member 80 is divided into three ranges, The user can accurately perform the object even if the pressure range of the user is separated by a certain margin.

The electrostatic capacity range or the resistance value range of the current between the first electrode member (70) and the second electrode member (80) can be controlled by the conductive powder (31a) distributed on the nanofibers of the nanofiber member The capacitance value or the resistance value of the current is surely changed according to the touch pressure, so that it is possible to make fine and accurate judgment about the touch pressure of the user.
