Description

TOUCH WINDOW AND TOUCH DEVICE "

Embodiments relate to a touch window and a touch device.

[0002] In recent years, a touch window has been applied to input images in a manner of touching an input device such as a finger or a stylus to an image displayed on a display device in various electronic products.

Such a touch window can be largely divided into a resistive touch window and a capacitive touch window. In the resistive touch window, the glass and the electrode are short-circuited by the pressure of the input device and the position is detected. The capacitive touch window senses the change in capacitance between the electrodes when a finger touches them, and the position is detected.

Recently, attention has been paid to a pressure sensor that detects not only a position according to a touch but also a pressure due to a force of a touch or a pressure, and performs various operations.

In the case of a display device formed by combining such a pressure sensor and a touch window, there is a problem that the thickness can be increased due to the structure of the pressure sensor added to the touch window.

Accordingly, a touch window and a touch device having a new structure capable of solving the above problems are required.

The embodiment attempts to provide a touch window capable of realizing a slim thickness.

A touch window according to an embodiment includes: a substrate on which a valid region and a non-valid region are defined; A first electrode disposed on the effective region and extending in a first direction; A second electrode disposed on the effective region and extending in a direction different from the first direction; And an elastic layer disposed between the first electrode and the second electrode.

A touch device according to an embodiment includes: a touch window; And a display panel disposed on the touch window, wherein the touch window includes: a substrate on which a valid region and a non-valid region are defined; A first electrode disposed on the effective region and extending in a first direction; A second electrode disposed on the effective region and extending in a direction different from the first direction; And an intermediate layer disposed between the first electrode and the second electrode, wherein the display panel includes a first substrate and a second substrate on the first substrate, And the second electrode is disposed in contact with the display panel.

The touch window according to the embodiment can simultaneously detect the position in the contacted area and the pressure of the force in the contacted area when the input device is contacted on one side of the substrate.

Accordingly, the touch window according to the embodiment and the touch device including the touch window can simultaneously detect the position and the pressure without adding a separate pressure sensing member, so that a touch window and a touch device having a slim thickness can be realized.

In addition, since the electrode recognizing the position and the electrode recognizing the pressure are used as one electrode, the position and the pressure can be simultaneously detected by one driving chip, so that the structure can be simplified and the process efficiency can be improved .

Further, in the touch device according to the embodiment, a part of the electrodes may be disposed on the display panel or inside the display panel, so that a separate substrate for supporting the electrodes can be omitted.

Further, since the touch window is bonded to the display panel by utilizing the intermediate layer, a separate adhesive layer can be omitted.

Accordingly, the touch window and the touch device according to the embodiment can dispense with a pressure sensing member, a substrate, and / or an adhesive layer for sensing a pressure, so that a touch device with a slim thickness can be realized.

Although the lower support 110 has a rectangular shape in the figure, the lower support 110 may have various shapes such as a circular shape.

The side support part 120 may surround the edge area of the lower support part 110.

The side support 120 may include a first side support 121 and a second side support 122.

Sapphire has excellent electrical properties such as dielectric constant, which not only greatly improves the speed of touch reaction but also can easily realize spatial touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

Also, the substrate 210 may be curved with a partially curved surface. That is, the substrate 300 may be partially flat and partially curved with a curved surface. In detail, the end of the substrate 300 may have a curved surface or may have a curved surface with a curvature, and may be curved or bent.

For example, the first electrode 221 and the second electrode 222 may include a plurality of sub-electrodes disposed to intersect with each other, and the first electrode 221 and the second electrode 222 may be formed by the sub- The second electrode 222 may be disposed in a mesh shape as a whole.

Since the first electrode 221 and the second electrode 222 have a mesh shape, the pattern of the first electrode 221 and the second electrode 222 can be made invisible on the effective region. That is, even if the first electrode 221 and the second electrode 222 are formed of metal, the pattern can be made invisible. Also, the resistance of the touch window can be lowered even if the first electrode 221 and the second electrode 222 are applied to a touch window of a large size.

In detail, the first electrode 221 and the second electrode 222 may include a mesh line formed by a plurality of sub-electrodes crossing each other and a mesh opening between the mesh lines.

The line width of the mesh line may be about 0.1 탆 to about 10 탆. The mesh line having a line width of the mesh line less than about 0.1 탆 may not be possible in the manufacturing process, and when the line width is more than about 10 탆, the sensing electrode pattern may be visually recognized from outside and visibility may be deteriorated. Alternatively, the line width of the mesh wire may be from about 1 [mu] m to about 5 [mu] m. Or, the line width of the mesh line may be about 1.5 탆 to about 3 탆.

Further, the thickness of the mesh line may be about 100 nm to about 500 nm. If the thickness of the mesh wire is less than about 100 nm, the electrode resistance may increase and the electrical characteristics may deteriorate.

In detail, the middle layer 230 has a Youngs modulus of about 1 MPa to about 2 MPa, a compressive modulus of about 150 MPa to about 200 MPa, a shear modulus of about 0.4 MPa to about 0.7 MPa, and a bulk modulus of from about 2 psi to about 3.5 psi.

When the input device contacts the substrate 210 by the first electrode 221, the second electrode 222 and the intermediate layer 230, the pressure according to the force of the input device can be sensed.

That is, the first electrode 221 may be disposed on the intermediate layer 230, and the second electrode 222 may be disposed on the lower portion of the intermediate layer 230.

At this time, a force is applied on one surface of the substrate by the input device, and the thickness of the intermediate layer 230 having elasticity can be changed by the force. Accordingly, the first distance between the first electrode 221 and the second electrode 222 before the force is applied by the input device may be changed to a second distance after a force is applied by the input device.

That is, the pressure of the force applied from the input device can be sensed through the amount of change of the first distance and the second distance.

The thickness of the intermediate layer 230 may be about 500 탆 or less. In detail, the thickness of the intermediate layer 230 may be about 100 탆 to about 500 탆. More specifically, the thickness of the intermediate layer 230 may be about 300 탆 to about 500 탆.

When the thickness of the intermediate layer 230 is greater than about 500 탆, the accuracy of the pressure applied to the input device may be degraded as the amount of change between the first distance and the second distance decreases.

When the thickness of the intermediate layer 230 is less than about 100 占 퐉, when the touch window 200 and the display panel 300 are bonded by the intermediate layer 230, the adhesive force is reduced, .

Further, when the input device is contacted on one surface of the substrate, the capacitance difference between the first electrode 221 and the second electrode 222 is changed, and the position of the contacted region Can be detected.

Accordingly, the touch window according to the embodiment and the touch device including the touch window can simultaneously detect the position and the pressure without adding a separate pressure sensing member, so that a touch window and a touch device having a slim thickness can be realized.

In addition, since the electrode recognizing the position and the electrode recognizing the pressure are used as one electrode, the position and the pressure can be simultaneously sensed by one driving chip, so that the structure can be simplified and the process efficiency can be improved .
