In the drawings, the thickness of layers, films, panels, regions, etc. have been exaggerated for clarity. Like reference numerals refer to like elements throughout the specification. It will be understood that when an element such as a layer, film, panel, or region is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected" to another element, there are no intervening elements present. As used herein, "connected" may refer to physical or electrical connections. Further, an "electrical connection" or "coupling" may be the presence of other elements between the two elements.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a "first element" discussed below could also be termed a "second element" without departing from the teachings herein.

As used herein, "about," "approximately," or "substantially" includes the average of the stated value and a specified value within an acceptable range of deviation of the stated value, as determined by one of ordinary skill in the art, given the particular number of measurements discussed and the errors associated with the measurements (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated values, or within ± 30%, ± 20%, ± 10%, ± 5%. Further, as used herein, "about", "approximately" or "substantially" may be selected based on optical properties, etching properties or other properties to select a more acceptable range of deviation or standard deviation, and not to apply one standard deviation to all properties.

Fig. 1 and fig. 2 are a top view and a bottom view of a cutting tool according to an embodiment of the invention, respectively, wherein fig. 2 shows hidden elements with dashed lines. Referring to fig. 1, in the present embodiment, the cutting jig 100 includes a supporting member 110 and a cutting line 120. The bearing member 110 includes an upper surface 111, a lower surface 112 (see fig. 2), a bearing surface 113 and a bearing surface 114. The upper surface 111 has a first opening 133 and a first opening 134, the first opening 133 is formed by a through hole 131, the first opening 134 is formed by a through hole 132, and the through

holes

131 and 132 respectively form second openings 135 and 136 (see fig. 2) on the lower surface 112 (see fig. 2).

The cut line 120 includes a first end 121 and a second end 122. The first end 121 passes out of the first opening 133 and the second end 122 passes out of the first opening 134.

Referring to fig. 2, the lower surface 112 of the support member 110 is opposite to the upper surface 111 (see fig. 1), and the through hole 131 forms a second opening 135 on the lower surface 112, and the through hole 132 forms a second opening 136 on the lower surface 112.

The through

holes

131 and 132 pass through the upper surface 111 (see fig. 1) and the lower surface 112, the bearing surface 113 and the bearing surface 114 are respectively connected between the upper surface 111 (see fig. 1) and the lower surface 112, and the second opening 135 on the lower surface 112 is adjacent to the bearing surface 113, and the second opening 136 on the lower surface 112 is adjacent to the bearing surface 114.

Referring to fig. 1 and fig. 2, the first end 121 of the cutting wire 120 enters the through hole 131 from the second opening 135 and penetrates out of the first opening 133. The second end 122 of the cutting wire 120 enters the through hole 132 from the second opening 136 and exits from the first opening 134. Thus, the cut line segment 123 may surround an area. When the first end 121 of the cutting line 120 is pulled along the direction d1 and the second end 122 of the cutting line 120 is pulled along the direction d2, the cutting line segment 123 of the cutting line 120 between the first end 121 and the second end 122 is contracted toward the bearing member 110.

For example, when the cutting line segment 123 of the cutting line 120 is sleeved on an object, such that the object is disposed in the area a surrounded by the cutting line segment 123, the cutting line 120 can cut the object in the area a surrounded by the cutting line segment 123 along the direction d3 in the shrinking process. On the other hand, the first end 121 and the second end 122 can protrude from the upper surface 111 of the supporting member 110, so that the user can pull the first end 121 and the second end 122 directly to contract the cutting line segment 123.

Specifically, referring to fig. 1, on the upper surface 111 of the support member 110, the first openings 133 and the first openings 134 are arranged along the first direction d4 and spaced by a first distance L1, and the support surface 113 and the support surface 114 are disposed on two sides of the support member 110 along the first direction d 4. Thus, the first opening 133 may be disposed adjacent the bearing surface 113, and the first opening 134 may be disposed adjacent the bearing surface 114.

Referring to fig. 2, on the lower surface 112 of the supporting member 110, the second openings 135 and the second openings 136 are arranged along the first direction d4 and spaced apart by a second distance L2, and the length of the second distance L2 is longer than the length of the first distance L1. Thus, second opening 135 may be disposed adjacent bearing surface 113, while second opening 136 may be disposed adjacent bearing surface 114.

On the other hand, since the length of the second distance L2 is longer than the length of the first distance L1, in the first direction d4, the distance between the through

holes

131 and 132 increases from the upper surface 111 to the lower surface 112 in the supporting member 110, and the cutting line segment 123 of the cutting line 120 can easily form an arc after passing through the second opening 135 and the second opening 136, and can be sleeved on the outer edge of a circular display panel in a display device. Since the pulling direction d1 of the cutting wire 120 after passing through the through-hole 131 and the pulling direction d2 of the cutting wire 120 after passing through the through-hole 132 are similar to the tangential direction of the circular arc, the user can more effectively drive the cutting line segment 123 to cut the area a when pulling the first end 121 and the second end 122 of the cutting wire 120.

On the other hand, the bearing surface 113 and the bearing surface 114 of the bearing member 110 each form an arc surface, so that the bearing surface 113 and the bearing surface 114 are adapted to bear against the inner edge of a circular housing.

Specifically, in the present embodiment, the support member 110 further includes a first side surface 115 and a second side surface 116 opposite to the first side surface 115. First side 115 and second side 116 each connect upper surface 111 and lower surface 112, and first side 115 and second side 116 each connect between bearing surface 113 and bearing surface 114. In the first direction d4, the bearing surface 113 and the bearing surface 114 form an arc on both sides of the bearing member 110, and the length of the first side surface 115 is longer than that of the second side surface 116, so that the bearing surface 113 and the bearing surface 114 are respectively inclined toward the second side surface 116. Thus, when the support member 110 is supported against the inner edge of a circular housing, the second side 116 with a shorter length can be closer to the inner edge of the circular housing.

On the other hand, the

first openings

133 and 134 are aligned along the first direction d4 on the upper surface 111, the

second openings

135 and 136 are also aligned along the first direction d4 on the lower surface 112, and the first side 115 and the second side 116 also extend along the first direction d 4.

Thus, the first opening 133 and the first opening 134 may be located adjacent to the second side 116 at the upper surface 111, and the second opening 135 and the second opening 136 may be located adjacent to the first side 115 at the lower surface 112. Since the second side 116 can be closer to the inner edge of a circular housing, the cutting line segment 123 extending out from the second opening 135 and the second opening 136 can be easily sleeved on a larger area of the circular housing.

Further, the through hole 131 and the through hole 132 may be obliquely disposed in the support member 110 with respect to the upper surface 111 and the lower surface 112 of the support member 110 to facilitate the passing of the cutting line 120.

FIG. 3 is a schematic cross-sectional view taken along section line 3 in FIG. 1. Referring to fig. 3, in the present embodiment, the through hole 131 extends along a straight line S1, and an included angle k1 between the straight line S1 and the normal N of the lower surface 112 is 45 degrees, but the invention is not limited thereto. In the embodiment of the present invention, the included angle k1 between the straight line S1 in the bearing member 110 and the normal N of the lower surface 112 is greater than 0 degrees and equal to or less than 45 degrees. Thus, the through-hole 131 of the rest element 110 is adapted to guide the cutting wire 120 such that the first end 121 of the cutting wire 120 can be passed out of the through-hole 131 in the direction d1, and the cutting wire segment 123 of the cutting wire 120 can be passed into the through-hole 131 in the direction d 3.

Fig. 4 is a schematic partial cross-sectional view of a cutting tool according to another embodiment of the invention. Referring to fig. 4, in other embodiments of the present invention, the supporting member 110A may further include a plurality of pulleys 137, and each pulley 137 may be disposed adjacent to the second opening 135. The first end 121 of the cutting line 120 passes around the pulley 137 into the second opening 135, while the second end of the cutting line 120 passes around another pulley into another second opening (not shown in figure 4).

Specifically, the pulley 137 may be disposed on a side of the lower surface 112 adjacent to the first side surface 115. Therefore, the cutting line 120 can change the pulling direction by the pulley 137, so that the cutting line segment 123 can be pulled along the direction d3, and the pulley 137 can guide the cutting line 120 so that the first end 121 can pass through the first opening 133 of the upper surface 111 along the normal direction n1 close to the upper surface 111.

In the present embodiment, the through hole 131 extends in a direction perpendicular to the lower surface 112, but the present invention is not limited thereto. In other embodiments, the normal vector of the through hole 131 and the lower surface 112 may also include an angle, which may not exceed 45 degrees.

Fig. 5 is a perspective view of the supporting member 110 according to an embodiment of the invention, wherein the hidden elements are shown in dashed lines. Referring to fig. 5, the bearing surface 113 is connected to the upper surface 111 and the lower surface 112, and the bearing surface 114 is connected to the upper surface 111 and the lower surface 112. The bearing surfaces 113 and 114 may be formed as arc surfaces, and the length of the first side surface 115 of the bearing member 110 in the first direction d4 is longer than the length of the second side surface 116, so that the bearing member 110 can bear against the inner edge of the outer shell of the circular display panel by the bearing surfaces 113 and 114.

Fig. 6 is a schematic perspective view of a cutting tool 100 and a display device according to an embodiment of the invention.

For example, fig. 6 is a schematic perspective view illustrating the back surface 51b of the display panel 51 facing upward, and the display surface of the display panel 51 opposite to the back surface 51b is adhered to the glass cover plate by the adhesive layer. Meanwhile, on the side adjacent to the back surface of the display panel 51, there is an annular groove 50g between the inner edge 53 of the case 52 and the display panel 51. The cutting jig 100 of the present embodiment can be placed on the display device 50, the lower surface 112 of the support member 110 of the cutting jig 100 can face the display panel 51, the support surface 113 and the support surface 114 of the support member 110 can support the inner edge 53 of the housing 52 of the display device 50, and the upper surface 111 of the support member 110 can be pressed by a user to further fix the relative position between the support member 110 and the display device 50. When the supporting member 110 is supported by the display device 50, the second openings 135 and 136 (see fig. 2) of the supporting member 110 are located adjacent to the annular groove 50g, so that the cutting line segment 123 extending out of the

second openings

135 and 136 can be easily sleeved around the adhesive layer of the display panel 51.

Specifically, the supporting member 110 of the cutting tool 100 can be fixed to the inner edge 53 of the housing 52 by the supporting surface 113 and the supporting surface 114, the cutting line segment 123 of the cutting line 120 can be sleeved around the adhesive layer of the display panel 51, and the first end 121 and the second end 122 of the cutting line 120 respectively pass through the first opening 133 and the first opening 134. By pulling the first end 121 and the second end 122 of the cutting line 120, the cutting line segment 123 can cut the adhesive layer under the display panel 51, so that the display panel 51 can be separated from the glass cover plate on the housing 52.

Referring to fig. 7, in the present embodiment, a glass cover 55 is disposed on the housing 52, the display panel 51 is connected to the glass cover 55 by an adhesive layer 54, and an annular groove 50g is formed between the housing 52 and the display panel 51. The segment 123 of the scribe line 120 can be moved to a position adjacent to the adhesive layer 54 in the ring-shaped groove 50 g. When the cutting line segment 123 moves along the direction d3, the cutting line segment 123 can cut the adhesive layer 54 between the display panel 51 and the glass cover 55, so that the display panel 51 and the glass cover 55 can be separated, and the display panel 51 can be taken out from the housing 52.

In the above embodiments, the material of the cutting line 120 may be metal or nylon, and in some embodiments, the cutting line 120 may also be a high-strength fishing line. On the other hand, the wire diameter of the cutting wire 120 may fall in the range of 0.05 to 0.2 mm, and the hole diameters of the through-

hole holes

131, 132 may fall in the range of 0.1 to 0.3 mm.

On the other hand, the through

hole holes

231 and 232 of the present embodiment are connected to each other at a side adjacent to the lower surface 212 (see fig. 9), that is, the through hole 231 and the through hole 232 together form a second opening 235 (see fig. 9) at the lower surface 212.

Fig. 15 is a schematic cross-sectional view of a cutting tool according to still another embodiment of the invention, wherein the thicknesses of the layers are enlarged and the cutting lines are omitted. Referring to fig. 15, in the present embodiment, the cutting jig 100A is similar to the cutting jig 100 of the above-mentioned embodiment, and includes a supporting member 110 and a cutting line, and the details of the same elements are not repeated herein. Compared to the cutting jig 100 described above, the cutting jig 100A further includes a heating stage 140, a cover plate 141, and a movable substrate 142.

Since the support member 110 is disposed on the heating stage 140, the display device 50 can be disposed between the support member 110 and the heating stage 140. When the display device 50 is disposed on the heating stage 140, the heating stage 140 can heat the display device 50, so as to increase the temperature of the adhesive layer 54 between the display panel 51 and the housing 52, so that the cutting lines can more easily cut the adhesive layer 54 to separate the display panel 51 from the housing 52.

The heating stage 140 may further include a heat conductive metal plate 143 disposed on one side of the movable substrate 142, and the heat conductive metal plate 143 may be made of aluminum, so as to improve the heating efficiency.

The cover plate 141 of the present embodiment is connected to the heating stage 140 in a flip manner, and the cover plate 141 has a pressing surface 144. The pressing surfaces 144 are used to respectively press the support member 110, so that the relative position between the display device 50 and the support member 110 can be fixed. At the same time, the cover panel 141 can be flipped along direction d7 to release the rest 110 and the display device 50.

The movable substrate 142 of the present embodiment is movably disposed on the heating stage 140, and the supporting member 110 may be disposed on the movable substrate 142. On the other hand, the heat conductive metal plate 143 of the heating stage 130 may further be formed with a structure for connecting the movable substrate 142, a rail, or a screw hole for fixing the movable substrate 142 by using the material property of metal.

For example, on the carrying plane 145 of the heating stage 140, the movable substrate 142 can move along the direction d6, and further can move along a direction perpendicular to the direction d6 and parallel to the carrying plane 145. Therefore, when the supporting member 110 and the display device 50 are disposed on the movable substrate 142, the movable substrate 142 can adjust the position between the display device 50 and the supporting member 110 relative to the cover 141, and adjust the position at which the pressing surface 144 of the cover 141 presses the supporting member 110, so as to provide a proper fixing effect for the display device 50 and the supporting member 110.

Fig. 16 is another schematic cross-sectional view of the cutting tool 100A of the present embodiment. In this embodiment, the cover plate 141 may further have a fixing structure 146, and when the pressing surface 144 presses the support member 110, the fixing structure 146 may extend to the movable substrate 142 to further press and fix the support member 110 and the display device 50.

In summary, the cutting jig of the embodiment of the invention can effectively separate the display panel adhered to the glass cover plate in the display device from the glass cover plate, so that the display panel can be taken out of the housing, and the possibility of damage to the display panel in the separation process can be reduced.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
