Touch Panel Structure for Precise Touch Sense and Enhanced Endurance and Manufacturing Method Thereof}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a touch panel used for a touch screen for inputting position information of an electronic display device and a method of manufacturing the same. Low touch pressure for the recognition, suppression of the drag point of the recognition point, secure durability against bending of the ITO (Induim Tin Oxide) thin film, and maintain the appearance quality by preventing the Newton ring, and can greatly increase the price competitiveness It relates to a structure of a touch panel and a method of manufacturing the same.

The touch panel applied to the touch screen has been developed in various ways such as resistive type, capacitive type, ultrasonic type, infrared type. Double-resistive four-wire touch panels and capacitive touch panels are widely used, and four-wire is widely used in small to large sizes of 20 inches or larger. Resistive five-wire touch panels are four-wire touch panels. This is also applied mainly in the medium-large size because the reliability of the panel can be greatly improved compared to the panel, and the pattern of the electrode forming the equipotential is similar to the electrode groups of the capacitive touch panel. However, in a mobile device such as a cell phone or a PMP, the thickness of the panel, the size of the outer dead zone, and the appearance are considered important, and thus a window type input device is used. Such a touch window is a resistive method and a capacitive method. The resistive method is most commonly used because of its simple structure and writing ability, and the capacitive method is used for its appearance and multi-touch function as important advantages.

1 is a view for explaining the structure of a general resistive touch panel. As shown in FIG. 1, in a general resistive touch panel, a touch panel upper panel (upper film substrate) and a touch panel lower panel (lower substrate) have a structure in which a double-sided adhesive is attached along an edge of a touch window area. The upper panel of the touch panel is a window PET (Polyethylene terephthalate) film with a window frame (frame or decoration) and an ITO PET coated ITO PET film attached to the front with OCA (transparent adhesive film), and silver on the ITO coated surface. Electrode wiring is screen printed. In the lower panel of the touch panel, PET film coated with ITO thin film (PC) (or tempered glass substrate) is generally attached to the front surface by OCA (transparent adhesive film), and silver electrode wiring and dot spacer ( dot spacers) are formed.

In particular, the portion of the upper plate and the lower plate bonded together by the double-sided adhesive along the edge of the touch window area is hardly fixed, and a step is formed in the double-sided adhesive portion of the edge for joining the touch panel upper plate and the lower plate. When the ITO thin film of the upper plate is pressed to make contact between the ITO thin film of the lower plate, a sharp bending may occur in the upper film.

As a result of the step difference, the PET film coated with the ITO thin film on the upper panel of the touch panel has a large durability problem such as breakage of the ITO thin film due to rapid bending at the stepped portion, and touches near the stepped portion. When inputting, the contact is dragged from the inside. In order to alleviate the problems caused in the stepped portion, a PET film having a high ductility in a multilayer structure is often used.

2 is a view for explaining a problem of a transparent conductive film breakage of a stepped portion in a general resistive touch window. A general resistive touch window has a structure in which the upper front surface is exposed to the outside. Therefore, if pressure is applied near the stepped portion formed by the double-sided adhesive tape at the edge, the ITO thin film on the top plate is likely to be damaged. In general, the distance that can achieve 100,000 write endurances using a stylus pen of 0.8R PES at 100μm gap step is 3.5mm or more at the stepped part when using 188μm single layer PET film, and PET (125) / OCA (27 ) / PET (23) um multilayer PET film is used to ensure durability only at 2.0mm or more from the stepped portion.

FIG. 3 is a view for explaining a touch recognition drag phenomenon caused by a stepped portion in a general resistive touch panel. In a typical resistive touch panel, the touch recognition pressure is not only high when touched near the stepped portion, but the contact between the upper plate and the lower plate is several mm in the touch active area (as shown in FIG. About 3mm) is dragged from the inside away. For this reason, a scroll bar or menu icon placed on the edge of a portable device requires almost 5 mm of window frame width, which is a significant limitation in product and instrument design.

Another important issue of the touch panel is the Newton ring problem caused by the bending of the silver electrode wiring printed as shown in FIG. 4 and the action of the double-sided adhesive. By wrapping the silver electrode wiring screen printed on the edge of the PET film of the top plate to create a fine curl (curl) on the top PET film by a double-sided tape for bonding the top plate and the bottom plate, which is often caused by the Newton ring defects.

As we have seen, resistive touch panels are not only a complex process of stacking multiple layers of film, but also durability issues due to exposure to external pressure on the stepped portion, input drag at the edges of the touch window area, printed silver There are various problems to be solved, such as the Newton ring problem caused by the bending of the electrode wiring and the action of the double-sided adhesive.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to replace the electrode wirings formed on the upper plate with a thin film wiring having good ductility in a touch panel such as a resistive film method, and at this time, The present invention provides a structure of a touch panel formed larger in the touch input area inward direction than a step portion and a method of manufacturing the same.

In addition, another object of the present invention, in order to overcome the problems caused by the step portion to protect from breakage of the bending of the transparent conductive film in another way to protect the window frame (frame or decoration) on the transparent conductive film of the upper panel of the touch panel The present invention provides a structure of a touch panel in which a) is formed larger than a step portion and electrode wirings formed thereon, and a method of manufacturing the same.

In addition, another object of the present invention is to form a flexible material on the transparent conductive film of the upper panel of the touch panel from the stepped portion into the touch input area to prevent breakage of the transparent conductive film due to the touch pressure near the stepped portion. In addition, the low-cost single-layer PET film coated with a transparent conductive film such as ITO enables more durable performance than the double-layer ITO coated PET film. Provides a structure of a touch panel that can be thinned and flattened, and even if the thickness of the double-sided tape is reduced, the appearance defect due to the Newton ring is remarkably reduced, and at the same time, the step is small so that drag can be suppressed during touch input near the stepped portion, and a manufacturing method thereof is provided. There is.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

5 is a view for explaining the structure of the touch panel 100 according to an embodiment of the present invention. Referring to FIG. 5, in the touch panel 100 according to the exemplary embodiment of the present invention, the upper surface of the touch panel (upper film substrate) 120 and the lower panel of the touch panel (lower substrate) 110 form edges of the touch input area. Therefore, the structure is bonded to the double-sided adhesive 130 in the form of a film or tape.

 The touch panel upper plate 120 is a transparent window of about 188 μm on which a window frame (frame or decoration) 121 is formed and a transparent conductive film such as a polyethylene terephthalate (PET) film and an ITO thin film (for example, a sheet resistance of 500 Ohms). The coated transparent PET film is attached to the front with OCA (transparent adhesive film), and on the transparent PET film coated with a transparent conductive film, one or a plurality of upper metal electrode wirings 122 are made of a material such as silver. It is formed by the screen printing method.

The touch panel lower panel 110 includes a transparent PET film coated with a transparent conductive film (for example, a sheet resistance of 500 ohms) such as an ITO thin film on a polycarbonate (PC) (or tempered glass substrate) on an OCA (transparent adhesive film). On the transparent PET film attached on the front surface and coated with a transparent conductive film, one or a plurality of lower metal electrode wirings 111 are formed of a material such as silver on the screen printing method, and then transparent dot spacers are scattered. do.

The bonding between the upper panel 120 and the lower panel 110 is a film or a tape having a thickness of about 10 to 100 μm between the upper metal electrode wiring 122 and the lower metal electrode wiring 111 along the edge of the touch input area. The double-sided adhesive 130 is inserted and applied by pressure so that the upper plate 120 and the lower plate 110 are combined to be maintained at a predetermined interval.

Here, in particular, the material of the upper metal electrode wiring 122 and the lower metal electrode wiring 111 may be a paint containing carbon or silver, or at least one of gold, silver, copper, aluminum, tin, chromium, nickel, and stainless steel. It may include a metal including. For example, the electrode wirings 111/121 having a Cr / Cu / Cr lamination structure may be used, and the electrode wirings 111/121 may be formed by printing silver (silver) liquid.

In particular, the upper metal electrode wiring 122 is preferably formed of a thin film having a thickness of 3 μm or less to improve ductility. In addition, the electrode wirings 111/121 may use a laminated structure of Cr / Cu / Cr to prevent corrosion or deterioration of the electrode material, and a protective coating thereon to prevent corrosion or deterioration of the electrode wirings 111/121. It is also possible to form a coating film by the like.

In the present invention, as shown in FIG. 5, the width of the upper metal electrode wiring 122 (the corresponding width in the case of one wiring or the width of the entire plurality of wirings in the case of a plurality of wirings) is increased to increase the width of the upper metal electrode wiring 122. A part of the entire width is formed beyond the step boundary of the double-sided adhesive 130 toward the touch input area, thereby preventing breakage due to bending of the transparent conductive film. The double-sided adhesive 130 covers the upper metal electrode wiring 122 so that the upper metal electrode wiring 122 is not exposed from the outside of the touch window frame while the stepped boundary is formed on the upper metal electrode wiring 122. Cover part of the full width of 122.

That is, by increasing the width of the upper metal electrode wiring 122 larger by A (for example, in the range of 0.1 to 5.0 mm) from the step boundary of the double-sided adhesive 130, as shown in FIG. The upper metal electrode wiring 122 formed over the stepped boundary at the time of input may reduce the occurrence of cracks in the transparent conductive film that may be caused by bending at the time of touch input. Particularly, when a touch input for inputting touch position information is made near the step boundary, that is, near the edge of the touch input area, the upper metal electrode wiring 122 formed over the step boundary is transparent to the upper surface of the touch panel 120. Bending is performed together with the film-coated PET film, and thus, damage to the bending of the transparent conductive film such as ITO thin film coated on the PET film can be reduced more than the case where the structure is not employed, thereby greatly improving durability. do. In addition, when touch input is made near the edge of the touch input area, the contact between the upper plate 120 and the lower plate 110 is dragged from the inside of the touch input area, thereby eliminating the possibility of inputting an unclear position information. This can significantly reduce the incidence of Newton rings.

As such, the size of the upper metal electrode wiring 122 formed over the step boundary may be in a range of 0.1 to 5.0 mm from the step boundary of the upper metal electrode wiring 122. The larger the range of the upper metal electrode wiring 122 than the step boundary line, the greater the effect. However, it is preferable that the upper metal electrode wiring 122 be defined to the same extent as above without limiting the size of the touch window area and not damaging the aesthetic appearance.

As shown in FIG. 5, the touch panel upper plate 120 includes not only a PET film coated with a transparent conductive film, but also a separate transparent PET film adhered from the front with an OCA film or the like on the back surface of the PET film coated with a transparent conductive film. . In such a separate transparent PET film, the window frame 121 is formed to have a width larger than the width of the upper metal electrode wiring 122 along the edge of the touch input region. In particular, the width of the window frame 121 may be larger by B (for example, about 0.5 mm) than the width of the upper metal electrode wiring 122 at left and right ends of the width of the upper metal electrode wiring 122. The transparent PET film on which the window frame 121 is formed is a part in which touch input is made, and is protected from abrasion due to the touch input, and by using the window frame 121 to prevent the wirings 111/121 and the lower part thereof from being visible, the aesthetic appearance. Is used for. The material of the window frame 121 may include a metal including one or more of a dielectric multilayer thin film coating, a colored paint, gold, silver, copper, aluminum, tin, chromium, nickel, or stainless steel.

Before the touch panel upper plate 120 and the lower plate 110 are bonded to each other, an electrode pad formed at the end of the lower metal electrode wiring 111 of the touch panel lower plate 110 using a hot bar, etc., is connected to the FPCB. It can be connected to (Flexible Printed Circuit Board). When the touch panel upper plate 120 and the lower plate 110 are bonded to each other and then operate as a touch screen, a signal may be input to the lower metal electrode wiring 111 through the FPCB, and a signal changed by touch may be output. Some electrode pads of the lower metal electrode wiring 111 are energized with the upper metal electrode wiring 122 by a dispensing hole method, etc., so that a signal can also be input to the upper metal electrode wiring 122. The changed signal can be output. Recently, in addition to the dispensing hole method, some connection terminals are connected to the electrode pads of the upper metal electrode wiring 111 by using double-sided terminal FPCBs in which the connection terminals of the FPCB are exposed from both sides of the upper and lower sides, and the other connection terminals are connected to the lower metal electrode wiring. A method of electrically connecting the electrode pad of 121 may also be used. The upper metal electrode wiring 122 and the lower metal electrode wiring 111 are wired to recognize x-axis or y-axis coordinates, and the touch panel 100 is mounted on a display screen of a display device such as an LCD module, a CRT, or a PDP. In this case, a predetermined processor inputs / outputs a signal through the FPCB and interprets a signal change output from the touch panel 100 to determine which x and y coordinates on the touch panel 100 have been touched. Operate to calculate a location. Accordingly, it is possible to function as a position input device capable of moving a cursor or the like on the display screen.

Up to now, the structure using a separate transparent PET film having a window frame 121 is formed in addition to the PET film coated with a transparent conductive film on the upper surface of the touch panel 120. Hereinafter, the touch panel upper plate 120 will be described with reference to FIG. The structure of the touch panel 200 according to another embodiment of the present invention will not be described in addition to the PET film coated with a transparent conductive film.

Referring to FIG. 7, in the touch panel 200 according to another embodiment of the present invention, a touch panel upper plate (upper film substrate) 220 and a touch panel lower plate (lower substrate) 210 may be formed on the double-sided adhesive 230. By bonding similar to FIG. Here, the method and structure in which the lower metal electrode wiring 211 is formed on the touch panel lower plate 210 are similar to those described with reference to FIG. 5.

However, as shown in FIG. 7, the upper metal electrode on the window frame 221 formed along the edge on the transparent film coated with a transparent conductive film such as one ITO without using a separate transparent film on the touch panel upper plate 220. The wiring 222 may be formed.

Here, similarly to FIG. 5, the width of the upper metal electrode wiring 222 is larger than the width of the lower metal electrode wiring 211 so that a part of the entire width of the upper metal electrode wiring 222 is the double-sided adhesive toward the touch input area. A stepped boundary line 230 is formed by A (for example, in the range of 0.1 to 5.0 mm). In addition, the width of the window frame 221 may be formed to be larger than the width of the upper metal electrode wiring 222 by B (for example, about 0.5 mm). As such, by adopting a structure using only a transparent film coated with a transparent conductive film on the touch panel upper plate 220, the light efficiency can be increased, and material cost and process cost can be greatly reduced. The material of the window frame 221 may include a metal including one or more of a dielectric multi-film coating, colored paint, gold, silver, copper, aluminum, tin, chromium, nickel, or stainless steel.
