Description

Touch Panel Sensor {TOUCH PANEL SENSOR}

The present invention relates to a touch panel sensor, and more particularly, to a touch panel sensor capable of sensing a touch position and a scroll of a finger.

Typical touch screens electrically detect the contact of a finger. A finger is a kind of conductor through which electricity can collect, and when a finger comes close to an electrode, an electric charge can be collected between the electrode and the finger. As the charge is collected, it becomes possible to measure the capacitance or capacitance between the finger and the electrode, which can be used to indirectly detect the touch of the finger.

In addition, since the touch screen should not cover the rear display module, the resistive electrode of the touch screen may be formed of a transparent transparent electrode material, for example, indium tin oxide (ITO) or the like as electricity flows.

In addition, a scroll detector may be located at the edge of the device where the display module is disposed to detect scrolling of a part of the body through which a finger passes. Since the screen of the display module has a limited area, it may be difficult to display a specific image as a whole. In such a case, another part of the specific image may be displayed through the scroll detector.

However, the display area of the display module may be limited by the scroll detection unit disposed adjacent to or around the edge of the display module, and it is easy to distinguish the user's touch operation through the touch screen and the scroll operation through the scroll detection unit. This may result in error behavior.

The present invention is integrally formed on the side of the display module and the display module is disposed on different planes, to detect both the contact position of the body on the display module and whether the body scrolls on the side of the device Provides a touch panel sensor that can be.

Although the present invention is integrally formed on the side of the display module and the display module disposed on the different plane, the touch panel sensor is attached to the curved portion of the personal mobile terminal, even if the short circuit of the resistance electrode is not shorted Even if not, it provides a touch panel sensor that can prevent the malfunction caused by the phase change.

The present invention provides a touch panel sensor that is easy to assemble and can eliminate unnecessary processes such as position adjustment.

According to an exemplary embodiment of the present invention for achieving the above object of the present invention, the touch panel sensor provided adjacent to the display module of the personal portable terminal is a coordinate sensor unit for providing a coordinate sensing area on the display module, And a scroll sensor unit extending from the side of the coordinate sensor unit to cover the side of the personal mobile terminal and providing a scroll sensing area on the side of the personal mobile terminal, the position of the point where the body part of the user touches on different planes. Check, and can be manufactured in one-piece touch panel sensor for detecting the scroll.

Hereinafter, the structures of the coordinate sensor and the scroll sensor will be described in detail. However, the coordinate sensing sensor unit and the scroll sensing sensor unit do not always have to be manufactured on at least one same insulating transparent film as described below, and in some cases, may be patterned on different insulating sheets.

For example, the coordinate sensing sensor unit and the scroll sensing sensor unit may be provided on the laminated upper transparent film and the lower transparent film, and the coordinate sensing sensor unit is formed to face the upper transparent film and the lower transparent film, respectively, corresponding to the coordinate sensing area. The sensing upper pattern and the coordinate sensing lower pattern may be included, and the scroll sensing sensor unit may include a scroll sensing pattern formed on at least one of the upper transparent film and the lower transparent film corresponding to the scroll sensing area.

Thus, in the case of patterning the scroll detection pattern of the scroll detection sensor unit, one of the coordinate detection upper or lower patterns of the coordinate detection sensor unit of the coordinate detection sensor unit may be simultaneously patterned. Accordingly, the scroll detection pattern and the coordinate detection pattern of the scroll detection sensor unit and the coordinate detection sensor unit may be patterned through fewer processes than the case of patterning through different process processes to form the scroll detection sensor unit and the coordinate detection sensor unit. .

In addition, the scroll detection sensor unit and the coordinate sensor unit is disposed on a different plane, for example, the coordinate sensor unit is located on the plane on which the display is arranged, the scroll sensor unit is located on the side of the personal mobile device is mounted display module In this case, the upper and lower transparent films may be refracted between the front and side surfaces of the personal mobile terminal in which the display module is disposed, but the scroll sensing pattern of the scroll sensing sensor unit is formed by patterning only one of the upper and lower transparent films. As a result, the upper and lower transparent films are not significantly affected by the refraction between the front and side surfaces of the personal mobile terminal, so that the scroll detection pattern is not shorted, and the lower transparent film is bent at the curved portion of the terminal and attached to the side. Error does not occur due to the phase change of the upper transparent film Do not.

In some cases, the coordinate sensor and the scroll sensor is provided in the laminated upper transparent film and the lower transparent film, the upper transparent film is formed to cover both the coordinate sensing area and the scroll sensing area, the lower transparent film is the coordinate sensing It can be formed to cover the area. In this case, the coordinate sensing sensor unit includes a coordinate sensing upper pattern and a coordinate sensing lower pattern formed to face the upper transparent film and the lower transparent film, respectively, corresponding to the coordinate sensing region, and the scroll sensing sensor unit corresponds to the scroll sensing region. It may include a scroll detection pattern formed on the bottom of the transparent film.

Even in this case, as in the case where the upper transparent film and the lower transparent film cover both the coordinate sensing region and the scroll sensing region, the scroll sensing pattern of the scroll sensing sensor unit may be patterned simultaneously with the upper sensing pattern of the coordinate sensing sensor unit. Even if the upper transparent film is refracted at the portion between the front and side of the personal mobile terminal where the upper transparent film is refracted, short circuit and refraction of the scroll sensing pattern are not generated and the malfunction of the scroll sensing pattern may be prevented from occurring. Can be.

In addition, the same effect can be obtained by providing both the coordinate sensor unit and the scroll sensor unit in one transparent film.

Since the touch panel sensor should consider light transmittance, transparent synthetic resin may be used as the material of the upper and lower transparent films, and the upper and lower coordinate sensing patterns of ITO (Indium Tin Oxide) having both translucency and conductivity Or IZO (indium zinc oxide) may be used.

However, although the scroll detection pattern for detecting the scroll does not necessarily require light transmission, in the present invention, since the scroll detection pattern may be patterned together with any one of the upper and lower coordinate sensing patterns, in order to realize the simplification of the process, the upper coordinate sensing upper Like the pattern and the coordinate sensing subpattern, the scroll sensing pattern is preferably made of indium tin oxide (ITO) or indium zinc oxide (IZO) having both light transmittance and conductivity.

However, the scroll detection pattern does not necessarily need light transmittance, and various materials such as gold, silver, aluminum, and alloys having conductivity may be used as the material to reduce material costs.

The touch panel sensor of the present invention is integrally formed on the side of the display module and the mobile terminal in which the display module is disposed on different planes, the contact position of the finger according to the contact position of the body in contact with the display module In addition, the user may sense a scrolling motion of a finger on the side of the personal mobile device.

In the touch panel sensor of the present invention, the coordinate sensing sensor unit and the scroll sensing sensor unit are formed on one sensor pad, but the resistive electrodes are separated from each other, so that the touch panel sensor is attached to the display surface and the side of the personal mobile terminal, and the connected part thereof is connected. Electrical short circuit can be prevented.

In addition, the scroll detection pattern of the scroll detection sensor unit is formed on any one of the upper and lower transparent films on which the coordinate sensing upper pattern and the coordinate sensing lower pattern are formed, so that the scroll sensing unit is refracted by the integrated touch panel sensor. Malfunctions caused by short circuits or phase changes in patterns can be prevented more efficiently.

When the touch panel sensor of the present invention is to pattern any one of the upper pattern and the coordinate sensing lower pattern of the coordinate sensing sensor unit, the number of processes may be reduced by patterning the scroll sensing pattern together with the scroll sensing sensor unit.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by quoting contents described in other drawings under such a rule, and the contents repeated or deemed apparent to those skilled in the art may be omitted.

The present invention relates to a touch panel sensor provided adjacent to a display module of a personal portable terminal.

Example 1

1 is a perspective view of a touch panel sensor applied to a personal portable terminal according to a first embodiment of the present invention.

Referring to FIG. 1, a coordinate sensing sensor 110 and a scroll sensing sensor 120 are formed on the front surface 11 and the side surface 12 of the personal portable terminal 10, respectively.

The user may select a desired point of the screen displayed by the display module 15 through the coordinate sensor 110, and scroll the screen displayed by the display module 15 through the scroll sensor 120. Can be.

The coordinate sensing sensor unit 110 and the scroll sensing sensor unit 120 are disposed on different backsides of the personal portable terminal 10, respectively, so that the front surface 11 of the personal portable terminal 10 having a limited front surface 11 area. The display module 15 having the largest area possible may be mounted on the display module, and the scroll sensor 120 may limit the display area of the display module 15 or may be disposed on the display module 15. It is relatively easy to distinguish the touch operation of 110 from the scroll operation through the scroll detection sensor unit 120, thereby effectively preventing an error operation.

2 is an exploded perspective view illustrating a touch panel sensor according to a first embodiment of the present invention applied to a personal portable terminal, and FIG. 3 is a cross-sectional view illustrating a structure of the touch panel sensor according to the first embodiment of the present invention.

Referring to FIGS. 2 and 3, the touch panel sensor 100 includes a coordinate sensor 110, a scroll sensor 120, and the upper transparent film 130 on which the sensors 110 and 120 described above are formed. ) And a lower transparent film 140.

The coordinate sensing sensor unit 110 provides the coordinate sensing region 111 on the display module 15 mounted on the front surface 11 of the personal mobile terminal 10, and the scroll sensing sensor unit 120 is the coordinate sensing sensor unit. It extends from the side of the 110 to cover the side 12 of the personal mobile terminal 10, thereby providing a scroll sensing area 121 on the side 12 of the personal portable terminal 10.

The angle of refraction of the coordinate sensor 110 and the scroll sensor 120 of the touch panel sensor 100 is the angle of refraction of the portion where the front surface 11 and the side surface 12 of the personal portable terminal 10 are connected. It can be determined by, the personal portable terminal 10 of the present embodiment is provided in the form of a bar (bar) so that the angle of refraction of the front 11 and the side 12 is approximately 90 °. Accordingly, the angle of refraction of the coordinate sensor 110 and the scroll sensor 120 of the touch panel sensor 100 also forms about 90 °. However, the angle of refraction of the front 11 and the side 12 in the personal portable terminal 10 may be changed according to the type of product, and thus the coordinate sensing sensor unit 110 and the scroll sensing of the touch panel sensor 100. Refractive angle of the sensor unit 120 may also be formed differently according to the type of product.

In addition, although the scroll detection sensor unit 120 of the present embodiment extends from one side of the coordinate detection sensor unit 110 to form the scroll detection sensor unit 120, in some cases, the front surface of the personal portable terminal 10. It may be formed extending from a plurality of side surfaces of the scroll detection sensor unit 120 provided in (11).

The coordinate sensor 110 and the scroll sensor 120 are electrically connected to a flexible printed circuit board (FPCB) having one end interposed between the upper transparent film 130 and the lower transparent film 140, the flexible circuit The other end of the substrate FPCB is electrically connected to a controller mounted inside the personal mobile terminal, and thus, each touch due to the touch and scroll operation of the user through the coordinate sensor 110 and the scroll sensor 120 may be caused. The controller may detect a change in capacitance of the electrode pattern.

As shown in FIG. 3, the coordinate sensor 110 and the scroll sensor 120 described above are provided in the stacked upper transparent film 130 and the lower transparent film 140.

The coordinate sensing sensor unit 110 corresponds to the coordinate sensing region 111 and has a coordinate sensing upper pattern 112 and a coordinate sensing lower pattern 114 formed to face the upper transparent film 130 and the lower transparent film 140, respectively. It includes.

The scroll detection sensor unit 120 includes a scroll detection pattern 122 formed on the upper transparent film 130 corresponding to the scroll detection area 121.

In the present exemplary embodiment, since the coordinate sensing upper pattern 112 and the scroll sensing pattern 122 are formed on the same upper transparent film 130, the process of patterning the patterns 112 and 122 may be performed in one process. Can be.

Of course, the scroll sensor 120 may be formed on any one of the upper transparent film 130 and the lower transparent film 140 in response to the scroll detection area 121, so that in another embodiment of the present invention The scroll detection pattern 120 may be formed on the transparent film 140. In this case, the coordinate sensing lower pattern 114 of the coordinate sensing sensor unit 110 and the scroll sensing pattern 122 of the scroll sensing sensor unit 120 may be patterned on the lower transparent film 140 at once.

That is, by simultaneously patterning the scroll sensing pattern 122 with either the coordinate sensing upper pattern 112 or the coordinate sensing lower pattern 114 as described above, the number of process steps for patterning is reduced and manufacturing time is shortened. can do.

In addition, in the touch panel sensor 100 of the present invention, the scroll detection pattern 122 of the scroll detection sensor unit 120 is used to coordinate upper pattern 112 and lower coordinate detection pattern 114 of the coordinate detection sensor unit 110. By forming on one of the upper and lower transparent films 130 and 140 to be formed, even if the upper and lower transparent films 130 and 140 are refracted at the refractive portion where the front surface 11 and the side surface 12 meet, the scroll detection An unnecessary process of adjusting the phase of the pattern 122 can be omitted, and the assembly process is simple.

In addition, when the upper transparent film 130 and the lower transparent film 140 is attached to the front 11 and side 12 of the personal portable terminal 10 in close contact, the front 11 and the side 12 is At the refracted portion that meets, malfunction due to a short circuit or a change in phase of the scroll detection pattern 122 can be prevented.

For reference, the coordinate sensing sensor unit 110 provided in the present exemplary embodiment may have both patterns such that the above-described two patterns may be contacted only at a predetermined pressure or higher between the coordinate sensing upper pattern 112 and the coordinate sensing lower pattern 114. The insulating member may be filled in between.

In addition, the patterning shape of the scroll detection pattern 122 of the scroll detection sensor unit 120 provided in this embodiment will be described in detail below with reference to FIGS. 4 to 9, and for convenience of description, the same elements are substantially the same. Numbers may be given and reference given in the other figures may be cited under these rules.

4 is a plan view illustrating one scroll detection sensor unit of a touch panel sensor according to a first embodiment of the present invention.

Referring to FIG. 4, the scroll sensor 120 is formed with a scroll sensing pattern 122 patterned on one surface of the upper transparent film 130.

The scroll detection pattern 122 may be provided as at least one resistance electrode 123 whose width is gradually changed with respect to the length direction of the scroll detection area 121. In this embodiment, the resistance electrode 123 has a triangular shape. One is provided.

The width of the resistive electrode 123 becomes wider as it moves downward in the drawing, and as the portion of the body faces downward, the change in capacitance becomes larger. Accordingly, the controller 160, which is electrically connected through the connection wiring, may measure the change in capacitance to determine whether the user scrolls.

Specifically, when the user sweeps down from the top of the scroll detection pattern 122, the capacitance increases, so that the controller 160 can recognize the scroll motion toward the downward direction, and the user moves up and down the scroll detection pattern 122. When the sweeping is reduced, the controller 160 may recognize that the capacitance is reduced and the scrolling operation is directed upward.

5 is a plan view illustrating another scroll detection sensor unit of a touch panel sensor according to a first embodiment of the present invention.

Referring to FIG. 5, the scroll sensing pattern 222 includes two resistance electrodes 223 and 224, and the changing tendency of the adjacent resistance electrodes 223 and 224 is opposite to each other.

Therefore, even when a part of the body touches different portions of the scroll sensing pattern 222, the touched position and the direction of the scroll may be the same because the touched area is the same and thus the capacitance change generated in the resistance electrodes 223 and 224 is the same. You can avoid the error of incorrect calculation.

Specifically, the touch positions of the portions A and B are different from each other or the touched areas are similar to the upper and lower portions of the scroll detection pattern 222, and the touched areas are similar between the portions A and B. The change in capacitance generated between and B may be the same, and thus, it may be difficult to determine whether the user scrolls from part A to part B or scrolls from part B to part A.

However, in the scroll detection pattern 222 according to the present embodiment, since the capacitance change of each of the resistance electrodes 223 and 224 is different, the control unit 260 may distinguish the position and the scroll direction. .

In detail, when the B portion passes through the portion A toward the A portion, the capacitance of the resistance electrode 223 formed in the inverted triangle gradually decreases, and the capacitance of the resistance electrode 224 formed of the triangle gradually increases. Accordingly, although the sum of the capacitances measured at each of the resistance electrodes 223 and 224 is the same, the scroll direction of the user can be recognized.

Referring to FIG. 6, the scroll sensing pattern 322 includes two resistance electrodes 323 and 324, and the changing tendency of the adjacent resistance electrodes 323 and 324 is opposite to each other.

In addition, reference electrodes 325 and 326 are formed on the upper transparent film 330 side by side with the resistance electrodes 323 and 324 interposed therebetween. The reference electrodes 325 and 326 have a constant width in the longitudinal direction of the scroll sensing region.

In some cases, when a part of the body is in contact with the same touched area (C, D) on one resistance electrode 323, despite touching different parts (C, D) of the scroll detection pattern 322 Since the touched areas (C, D) are the same, the capacitance change generated in the resistance electrodes 323 and 324 is the same, and an error in which the touch position is incorrectly calculated may occur. In this case, when the user moves through the control unit 360, it is difficult to distinguish the direction of the scroll.

However, the scroll sensor 320 of the present embodiment can perform the scroll operation only when the two reference electrodes 325 and 326 having the resistance electrodes 323 and 324 are all sensed. By doing so, it is possible to prevent a calculation error of a contact position that may occur by touching a similar area on the same resistive electrodes 323 and 324, and to easily recognize the scroll direction.

7 is a plan view illustrating another scroll detection sensor unit of a touch panel sensor according to a first embodiment of the present invention.

Referring to FIG. 7, the scroll detection pattern 422 includes a plurality of resistance electrodes 424 having different lengths, and each resistance electrode 424 is arranged in the width direction of the scroll detection area 421. Accordingly, the controller 460 scrolls by using the number of the resistance electrodes 424 to be touched or the change in the length of the longest resistance electrode 424 among the touched electrodes 424 according to the direction in which a part of the body touches and passes. The direction of can be calculated easily.

8 is a plan view illustrating another scroll detection sensor unit of the touch panel sensor according to the first embodiment of the present invention.

Referring to FIG. 8, the scroll detection pattern 522 is provided as a single resistance electrode 523, but the width of the resistance electrode 523 is provided in a step shape in which the width of the resistance electrode 523 increases or decreases gradually in the longitudinal direction. do.

Referring to FIG. 9, the scroll detection pattern 622 is provided as a resistance electrode including a plurality of electrode parts 623 to 627 arranged in the length direction of the scroll detection area 621.

Each of the electrode parts 623 to 627 includes a first node pattern 623a to 627a and a second node pattern 623b to 627b that are adjacent to each other but are electrically separated from each other. The resistance ratios of the first node patterns 623a to 627a and the second node patterns 623b to 627b are different from each other among the adjacent electrode parts 623 to 627.

As shown in FIG. 9, the resistance ratios of the first node patterns 623a to 627a and the second node patterns 623b to 627b include the first node patterns 623a to 627a and the second node patterns 623b to 627b. It can be determined by the difference between the width (D1, D2) of.
