For a better understanding of the features and technical aspects of the present invention, reference should be made to the accompanying drawings.

[First Embodiment]

Please refer to FIG. 1, which is a partial side cross-sectional view of the first embodiment of the present invention. As shown in the above figure, the first embodiment of the present invention provides a touch panel module capable of naturally aligning a center position, comprising: a frame unit 1 and a touch panel unit 2.

First, the frame unit 1 includes a hollow frame body 10, wherein the hollow frame body 10 has an accommodating space 100 recessed downward from the top end 10T of the hollow frame body 10, and an inner space formed in the hollow frame body 10. a surrounding positioning surface 101 on the bottom surface facing the accommodating space 100, and a stepped structure 102 formed on the inner side surface of the hollow frame body 10 and surrounding the accommodating space 100.

For example, the hollow frame body 10 has an opening 103 that communicates with the accommodating space 100 and the bottom end 10B of the hollow frame body 10. In addition, since the stepped structure 102 can be a surrounding stepped structure, the stepped structure 102 has a first surrounding side 1020 extending upward from the surrounding positioning surface 101, and a first surrounding side 1020. An outer surrounding first surrounding bottom surface 1021, a second surrounding side surface 1022 extending upward from the first surrounding bottom surface 1021, a second surrounding bottom surface 1023 extending outwardly from the second surrounding side surface 1022, and a second from the second A third surrounding side 1024 extends upwardly about the bottom surface 1023 and is coupled to the top end 10T of the hollow frame body 10. Additionally, the first surrounding side 1020 is substantially perpendicular to the surrounding positioning surface 101, the first surrounding bottom surface 1021 being substantially perpendicular to the first surrounding side 1020, the second surrounding side 1022 being substantially perpendicular to the first surrounding The bottom surface 1021 , the second surrounding bottom surface 1023 is substantially perpendicular to the second surrounding side surface 1022 , and the third surrounding side surface 1024 is substantially perpendicular to the second surrounding bottom surface 1023 and the top end 10T of the hollow frame body 10 . In other words, the first surrounding side surface 1020, the first surrounding bottom surface 1021, the second surrounding side surface 1022, the second surrounding bottom surface 1023, and the third surrounding side surface 1024 may be sequentially connected to form the stepped structure 102.

In addition, the touch panel unit 2 can be a resistive touch panel structure. Therefore, the touch panel unit 2 can be disposed at least in the accommodating space 100 and disposed through the plurality of adhesive elements H. a transparent substrate 20 (for example, transparent glass) on the surrounding positioning surface 101 of the hollow frame body 10, and a transparent conductive film 21 (for example, an ITO film) disposed in the accommodating space 100 and disposed on the transparent substrate 20, The first shortest distance D1 of the outer surrounding circumference 200 of the transparent substrate 20 from the stepped structure 102 is smaller than the second shortest distance D2 of the outer surrounding circumference 210 of the transparent conductive film 21 from the stepped structure 102. For example, the first shortest distance D1 is the shortest distance of the outer surrounding circumference 200 of the transparent substrate 20 from the first surrounding side surface 1020 of the stepped structure 102, and the second shortest distance D2 is the transparent conductive film 21 The outer circumference around the circumference 210 is the shortest distance from the third surrounding side 1024 of the stepped structure 102.

The central position within the hollow frame body 10. In addition, since the stepped structure 102 has a stepped shape, when the touch panel unit 2 is disposed on the surrounding positioning surface 101 of the hollow frame body 10 through the plurality of adhesive elements H, it is electrically connected to The wires (not shown) of the touch panel unit 2 can achieve the effect of being shielded, thereby increasing the aesthetics of the touch panel module of the present invention.

[Second embodiment]

Please refer to FIG. 2, which is a partial side cross-sectional view of a second embodiment of the present invention. As shown in the above figure, the second embodiment of the present invention provides a touch panel module capable of naturally aligning a center position, comprising: a frame unit 1 and a touch panel unit 2.

First, the frame unit 1 includes a hollow frame body 10, wherein the hollow frame body 10 has an accommodating space 100 recessed downward from the top end 10T of the hollow frame body 10, and an inner space formed in the hollow frame body 10. a surrounding positioning surface 101 on the bottom surface facing the accommodating space 100, and a stepped structure 102 formed on the inner side surface of the hollow frame body 10 and surrounding the accommodating space 100.

For example, the hollow frame body 10 has an opening 103 that communicates with the accommodating space 100 and the bottom end 10B of the hollow frame body. In addition, since the stepped structure 102 can be a surrounding stepped structure, the stepped structure 102 has a first surrounding side 1020 extending upward from the surrounding positioning surface 101, and a first surrounding side 1020. An outer surrounding first surrounding bottom surface 1021, a second surrounding side surface 1022 extending upward from the first surrounding bottom surface 1021, a second surrounding bottom surface 1023 extending outwardly from the second surrounding side surface 1022, and a second from the second A third surrounding side that extends upwardly about the bottom surface 1023 and is coupled to the top end 10T of the hollow frame body 10. Additionally, the first surrounding side 1020 is substantially perpendicular to the surrounding positioning surface 101, the first surrounding bottom surface 1021 being substantially perpendicular to the first surrounding side 1020, the second surrounding side 1022 being substantially perpendicular to the first surrounding The bottom surface 1021 , the second surrounding bottom surface 1023 is substantially perpendicular to the second surrounding side surface 1022 , and the third surrounding side surface 1024 is substantially perpendicular to the second surrounding bottom surface 1023 and the top end 10T of the hollow frame body 10 . In other words, the first surrounding side surface 1020, the first surrounding bottom surface 1021, the second surrounding side surface 1022, the second surrounding bottom surface 1023, and the third surrounding side surface 1024 may be sequentially connected to form the stepped structure 102.

For example, the first shortest distance d1 is the shortest distance of the outer surrounding circumference 200 of the transparent substrate 20 from the second surrounding side surface 1022 of the stepped structure 102, and the second shortest distance d2 is the transparent conductive film 21 The outer circumference around the circumference 210 is the shortest distance from the first surrounding side 1020 of the stepped structure 102.

Therefore, since the first shortest distance d1 of the outer surrounding circumference 200 of the transparent substrate 20 from the second surrounding side surface 1022 of the stepped structure 102 is very small (for example, may approach 0.1 μm), when the touch panel unit 2 when the plurality of adhesive elements H are disposed on the surrounding positioning surface 101 of the hollow frame body 10, the touch panel unit 2 can be naturally aligned and positioned without using a jig.
