Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description with reference to the accompanying drawings, the same reference numerals denote the same elements regardless of the reference numerals, and redundant description thereof will be omitted. The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another.

3 and 4 are a process flow chart and a process conceptual view showing a part of the manufacturing process of the touch window according to the present invention.

Referring to FIGS. 3 and 4, the touch window according to the present invention forms at least one print pattern in an inactive region, which is an outer portion of the transparent window, and a portion of the print pattern is opened to expose the transparent window. And forming a transflective ink layer on the transparent protective layer on the transflective ink layer.

In the manufacturing process, the process of forming a printing pattern may be implemented by coating a multilayer printing material on an outer portion of the active area A on a transparent window, in which case the printing pattern is an infrared sensor unit IR. Preferably, the printing process is performed to implement the openings formed therein. The printing pattern may be implemented by a single layer or a multilayer printing process. In the present invention, after the formation of the printing pattern, a semi-transmissive ink layer (IR ink coating) and a transparent protective layer on the upper surface of the semi-transparent ink layer are formed on the opening. It is the point to do it.

Referring to FIG. 4, this illustrates the process indicated by the process of forming the first print pattern in FIG. 3, and illustrates the case where the multilayer printing method is applied. Referring to this, first, (a) a 1 degree printing process is performed on the entire printing area of the substrate for a touch window. In the first degree printing process, the printing is performed on an area in which the open area for forming the infrared sensor unit IR, the button part B, and the logo part R is excluded.

As in (a), after the first degree printing process, (b) process the second degree printing process on the logo portion (R). In this case, the printing material applied in the second degree printing process may be different from the printing material applied in the first degree printing process. This is because the first degree printing material is coated with a black ink to make the wiring part invisible, whereas the second degree printing material applied to the logo part is to make the logo part stand out from the user. Because it is applied.

Then, as shown in (c), the third degree printing process may be processed to reinforce the first degree printing and the second degree printing.

Subsequently, (d) the fourth degree printing process is to apply an infrared sensor (Infrared Sensor). Specifically, the process of applying the infrared ink constituting the infrared sensor unit according to the present invention can be performed. That is, in the present invention, a process of forming a semi-transmissive ink layer and a transparent protective layer laminated on the semi-transparent ink layer is performed on the opening constituting the infrared sensor unit R.

  Then, as shown in (e) the 5 degree printing process is to apply the button portion. In this case, the fourth degree printing material applied in the fourth degree printing process and the fifth degree printing material applied in the fifth degree printing process may be the same or different according to embodiments.

The multilayer implementation of the above-described printing according to the present invention described with reference to FIG. 4 is just one embodiment, and the gist of the present invention does not vary accordingly, and the gist of the present invention is transparent as shown in FIG. 5. The printing pattern 20 is implemented on the window 10, and the transparent protective layer 40 is formed on the semi-transparent ink layer 30 and the semi-transparent ink layer 30 on the opening for the infrared sensor unit formed when the printing pattern is implemented. Is to include the process of implementing).

That is, the touch window according to the present invention implements the transparent protective layer 40 on the semi-transparent ink layer 30, and then implements the semi-transparent ink layer by a high temperature process such as a deposition process when the sensing electrode for the active region is implemented. An advantage is realized so that damage to 30 can be prevented. To this end, the transparent protective layer according to the present invention, it is preferable to be implemented with a non-conductive insulating material to minimize the electrical interference. Furthermore, it is preferable to use a material having a transmittance of 95 to 99% or more so as not to interfere with the transmittance control of the semi-permeable ink layer 30. For example, the transparent protective layer may be implemented by at least one of SiO 2 , SiNx, Al 2 O 3 , HfO, ZrO, TiO 2 , and ZnO. Furthermore, as shown in FIG. 5, the transparent protective layer 40 is directly stacked on the semi-permeable ink layer 30, but may be implemented if more than the width of the opening is formed at a position corresponding to the opening. In order to prevent damage, the semi-transparent ink layer 30 may be formed to cover the whole.

In addition, the transparent protective layer 40 may be implemented to be stacked in at least two or more layers, in this case it can be configured to include a layer composed of different materials in the insulating layer adjacent to each other in the stacked structure.

7 to 13 are views for explaining various embodiments of the touch window according to the present invention.

7, as described above, an active area (V / A) for sensing a touch, an inactive area (D / A) in which a printing pattern is printed, and a function key area (F / A) in which a function button is implemented are illustrated. A plan view of a touch window having a general structure, and in the present invention, by forming a transparent protective layer on the semi-transparent ink layer of the infrared sensor unit IR formed in the touch window, a sensing electrode pattern is formed in the active region V / A. In the deposition process, the semi-permeable ink layer may be implemented to protect the structure.

The touch window in which the subject matter of the present invention is realized may be applied to various structures according to the structure of forming the sensor electrode, that is, the sensing electrode pattern. That is, it can be applied to various kinds of touch panels including an infrared sensor unit, but most preferably, when a sensing electrode pattern is formed on a transparent window (substrate) that implements an infrared ray, that is, heat or pressure It is preferable to apply to a structure in which the infrared sensor unit is exposed to the applied process.

As an example of such a structure, as shown in FIG. 8, the sensing electrode patterns Tx and Rx may be directly applied to one surface of the transparent window 110. For example, the sensing electrode pattern is implemented on the surface of the transparent window 110 in which the active region (V / A) in FIG. 7 is implemented. In this case, after forming the infrared sensor unit, the sensing electrode pattern is patterned. Since the process proceeds to the process, there is a great risk of denaturation of the IR ink (semi-transparent ink layer) of the infrared sensor unit.

Referring to the structure of the touch window through the structure of FIG. 8, the first sensing electrode pattern 120 is formed on the transparent window 110, and the second sensing electrode pattern cells 131 are formed. Specifically, the first sensing electrode pattern 120 and the second axis sensing electrode pattern cells 131 may be formed by etching, sputtering, or screen printing. Generally, ITO (Indium-Tin Oxide) is used.

By forming an insulating pattern 150 on the second sensing electrode pattern cell 131 formed as described above, and forming a bridge electrode on the formed insulating pattern 150, the second axis conductive pattern cell 131 spaced apart from each other. The bridge electrode 190 may be implemented in a structure in which the electrical connection.

In this case, the same insulating layer as the insulating pattern 150 may be further stacked on the formation position of the transparent protective insulating layer according to the present invention in the process of forming the insulating pattern 150. Through this, it can be implemented to perform the function of reinforcing the damage of the transparent protective insulating layer in a continuous process.

As such, the structure of forming the sensing electrode on one transparent window substrate may be formed into various structures and is not limited to the illustrated structure.

For example, as shown in FIGS. 9 and 10, the first sensing electrode pattern 220 including the cells 221 connected in the direction of the first axis on the substrate and the second sensing spaced apart from each other in the direction of the second axis Cells 231 of the electrode pattern are formed. The first sensing electrode pattern cells 221 are connected to each other by the conductive lead 223, where the first axis and the second axis are orthogonal to each other so that the first conductive pattern 220 and the second conductive pattern 230 are formed. Can be implemented in a structure that is orthogonal to each other.

10 illustrates a process for implementing such a structure. Referring to this, the insulating layer 240 is formed on the first sensing electrode pattern 220 and the second sensing electrode pattern 230, and at this time, the offset is OFF. The insulating layer 240 may be formed using a -SET or ink-jet process. After the insulating layer 240 is disposed, the hole 241 is formed in the insulating layer 240 so that the upper surface of the second sensing electrode pattern cell 231 is exposed, but the second sensing is performed. It is formed to be narrower than the width of the electrode pattern cell 231. Since the holes 241 are used to electrically interconnect the second sensing electrode pattern cells 231, the holes 241 are formed at positions corresponding to the second sensing electrode pattern cells 231, respectively. Thereafter, a conductive material is coated on the insulating layer 240 and the hole 241 to form a conductive material coating layer 250. As shown in FIG. 10 (d), as the conductive material is applied onto the insulating layer 240 and the hole 241, the conductive material flows into the hole 241 and the insulating layer 240 other than the hole 241. ), A conductive material coating layer 250 is formed. Subsequently, a portion of the conductive material coating layer 250 is removed to form a bridge electrode 251 interconnecting the plurality of second conductive pattern cells 231. In more detail, the bridge electrode 251 generated as described above is described in detail. The pillar portion 252 and the pillar portion penetrate the insulating layer 240 through the hole 241 and are connected to the second conductive pattern cell 231. It consists of a body portion 253 interconnecting 252. The pillar portion 252 is formed in the vertical direction with respect to the horizontal direction of the substrate 210, the body portion 253 is formed on the insulating layer 240 of the substrate 210, at this time the horizontal direction of the substrate 210 Is formed in the same horizontal direction as

Such a bridge electrode 251 may be formed in various thicknesses in consideration of electrical resistance characteristics. The conductive material may be a conductive polymer in carbon nanotube (CNT) or silver nano-wire, molybdenum (Mo) and silver (Ag) alloy, or nickel (Ni) and chromium (Cr). It is preferable to select and form any one of the alloys.

The above process has described an example of the formation structure of various sensor electrodes of the touch window, and the structure of directly forming the first and second sensing electrode patterns implementing the functions of Tx and Rx on the transparent window substrate is the gist of the present invention. Can be applied.

Of course, besides the structure of simultaneously forming the first and second sensing electrode patterns for implementing the functions of Tx and Rx on the transparent window, any one of the first and second sensing electrode patterns for implementing the functions of Tx and Rx is transparent. The gist according to the present invention can also be applied to a structure formed in a window and forming another sensing electrode pattern on an independent substrate.

That is, in FIG. 11, the transparent window 210 illustrates a structure in which the first and second sensing electrode patterns 220 and 230 simultaneously implement the functions of Tx and Rx, and 'X' is an effective area. Is the active area (V / A; View Area), and 'Y' is the inactive area (D / A; Dead Area) where the wiring pattern 270 connected to the sensing electrode pattern is formed, and 'Z' is inactive. A circuit pattern 260 for implementing a print pattern 240 and a function key (F / A) in the area is shown.

Unlike this, as shown in FIG. 12, the first sensing electrode pattern 332 is directly formed on one surface of the transparent window 300, and the second sensing electrode pattern 312 is formed on a separate transparent substrate 330. The structure to form also can apply the summary of this invention. That is, after forming the infrared sensor portion on the inactive region of the transparent window 300, the transparent protective layer is laminated, and then the first sensing electrode pattern 332 is implemented, in this case the infrared sensor portion This is because the translucent ink layer constituting may be affected and damaged. In this structure, 'X' is an active area (V / A; view area) which is an effective area, and 'Y' is an inactive area (D / A; dead area), and wiring patterns 311 and 331 connected to the sensing electrode pattern. In this formed portion, 'Z' represents a circuit pattern 313 that implements the print pattern 301 and a function key (F / A) in the inactive area.

The touch window according to the present invention described above can be applied to various display devices in combination with the liquid crystal module. For example, in the liquid crystal display device which is a light emitting device using a backlight unit (BLU) as a light emitting module, the above-described structure is formed on the upper part of the liquid crystal module including a thin film transistor, a liquid crystal and a color filter, and a plurality of polarizing films. Touch windows can be combined.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention.
