This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2021-0093138, filed on Jul. 15, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
One or more embodiments relate to an attachment apparatus for attaching a protector, which is for protecting a display unit of a foldable electronic device, to a display unit of a foldable electronic device and a display protector attachment kit including the display protector attachment apparatus. More particularly, one or more embodiments relate to a protector attachment apparatus that enables simple and accurate attachment of a protector, which is for protecting a display unit of an electronic device in which a display unit may fold, to a display unit and a display protector attachment kit including the protector attachment apparatus.
Recently, electronic devices, such as smart devices and mobile devices, have become expensive products and have a display unit on the front, and accordingly, a structure in which a cover glass is applied to the front surface of a display unit to protect a touch panel is provided.
However, the cover glass has a high risk of damage or breakage due to factors including physical impact or dropping. When the cover glass needs to be repaired due to damage or breakage, the repair costs are considerable compared to the original selling price of an electronic device, and a considerable amount of time is required for the repair. In addition, such a damaged cover glass has a sharp surface, and thus, a user may be injured or operation of an electronic device itself may be poor. However, in spite of the aforementioned damage risk and inconvenience due to the high repair costs in case the cover glass of the electronic device is damaged or broken, a user frequently continues to use the electronic device having the broken cover glass and often ignores minor damage such as scratches. Therefore, an improved method for a typical consumer to easily attach a protective glass or protective film to a display of a smart device is required. However, there are often cases where a protective glass or protective film is not attached in the correct position on a display of an electronic device in the process of attaching a protective glass or protective film to a display of an electronic device or dust ends up between a display of an electronic device and a protective glass or protective film during the attachment process. To overcome these problems, there is a need for a typical consumer to easily attach a protective glass or protective film directly to a display unit of an electronic device.
To meet this need, an attachment apparatus for attaching a display protector, such as a protective glass or protective film, only for an electronic device having a non-folding flat-type display unit has been developed.
However, as an electronic device of which a display unit is foldable has recently been developed, it has become necessary to attach a protective glass or protective film (collectively referred to as a “protector”) also to a display unit of such a foldable electronic device. In the case of a foldable display unit, a recess is formed in the foldable area, and thus, in attaching a protector to a surface of the foldable display unit including the recess, a protector attachment apparatus for a non-folding display unit in the art is not suitable.
One or more embodiments include a display protector attachment apparatus for a foldable electronic device and a display protector attachment kit including the same, wherein the display protector attachment apparatus is configured to facilitate accurate alignment of a display protector for a foldable electronic device of which a display unit is foldable.
One or more embodiments include a display protector attachment apparatus for a foldable electronic device and a display protector attachment kit including the same, wherein the display protector attachment apparatus is configured to enable a display protector for a foldable electronic device of which a display unit is foldable to be attached in close contact with a recess of a folding line of the foldable display unit of the foldable electronic device.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments of the disclosure.

Here, the release film-first extension unit may have a release film-first extension unit-first through hole and a release film-first extension unit-second through hole that respectively have a shape complementary to the horizontal cross-sections of the first end-first fixing pin and the first end-second fixing pin on the frame-first end member of the frame unit and are configured to accommodate the first end-first fixing pin and the first end-second fixing pin, respectively. The release film-second extension unit may have a second extension unit-first through hole configured to accommodate the second end-side fixing pin of the inclination-forming fixing unit.
The release film-second extension unit may further have, on the circumferential surface of the second extension unit-first through hole, an extension unit-first incision line formed extending in a direction opposite to the direction in which the release film-first extension unit is located.
The extension unit-first incision line may be formed in contact with the circumferential surface of the second extension unit-first through hole.
Meanwhile, the extension unit-first incision line may be configured to be opened by the second end-side fixing pin when a tensile force is applied to a body of the release film.
The release film-second extension unit may have a second extension unit-second through hole spaced apart from the second extension unit-first through hole in the longitudinal direction of the release film.
The release film-second extension unit may further have, on the circumferential surface of the second extension unit-second through hole, an extension unit-second incision line formed extending in the direction in which the release film-first extension unit is located.
In addition, the display protector attachment kit may further include a squeeze member configured to apply a force to the protector film assembly to separate the display protector from the release film of the protector film assembly. The squeeze member may include: a blade unit configured to press the protector film assembly against the foldable display of the foldable electronic device and extend in a length corresponding to the width of the foldable display unit of the foldable electronic device; and a wing from a side surface of the squeeze member, arranged at each of both ends of the blade unit to extend from the side surface of the squeeze member, wherein a groove having a width greater than a thickness of the frame side member of the frame unit is in both ends of the blade unit and is between the blade unit and the squeeze member.
A tangent value for the angle of inclination formed by the inclination-forming fixing unit may be in a range of about 40 mm/206.74 mm to about 80 mm/206.74 mm.

The frame unit 110 may include a frame side member 112a extending between the frame-first end member 112c and the frame-second end member 112b. The frame-first end member 112c, the frame-second end member 112b, and a pair of frame side members 112a facing each other and extending side-by-side between the frame-first end member 112c and the frame-second end member 112b may define a seating space 113, in which a foldable electronic device may be seated in an unfolded state for attachment of a protector film.
A surface of the frame-first end member 112c is formed higher than the frame side member 112a so that a stepped portion 112d may be formed. When a foldable electronic device is placed, the surface of the frame-first end member 112c is higher than a display unit of the foldable electronic device due to the stepped portion 112d, and thus, a squeeze member 150 (see
On a bottom surface of the seating space 113, the frame-first end member 112c, the frame-second end member 112b, and the frame side member 112a are in contact to form a seating surface 114. The seating surface 114 may include a camera protrusion-accommodating hole 114d for accommodating a main camera protrusion formed protruding from a case portion arranged on the rear surface of the foldable display unit of the foldable electronic device.
Referring to
The protector body 220 may be formed to have a predetermined size corresponding to the size of the foldable display unit of the foldable electronic device to which the protector body 220 is attached, and the release film 210 may be attached to an upper surface 222 opposite to a protector attachment surface 221 that is to be attached to the foldable display unit of the foldable electronic device.
The protector body 220 and the release film 210 may be attached to each other by the properties of their materials themselves or by a separate adhesive member, and may be separated from each other when a predetermined force is applied thereto.
The release film 210 may include: a release film body 212 corresponding to the shape of the protector body 220 but having a size slightly larger than the protector body 220; a release film-first extension unit 216 arranged at one end of the release film body 212 and extending further than the protector body 220; and a release film-second extension unit 214 arranged at another end of the release film body 212 and extending further than the protector body 220. The release film 210 may be formed of a material having predetermined flexibility and elasticity.
Referring back to
The inclination-forming fixing unit 120 may include a vertical extension unit member 122 that protrudes and extends in a vertical direction (i.e., z direction in the drawing) to increase a mounting height of a portion corresponding to the release film-second extension unit 214 of the protector film assembly 200. The vertical extension unit member 122 may include a protruding piece 124 to be attached to an insertion hole 116a of the frame-second end member 112b of the frame unit 110. Around the insertion hole 116a, a pair of support ribs 116b may be provided to guide the insertion path of the vertical extension unit member 122 and to firmly maintain a position of the vertical extension unit member 122 mounted onto the frame-second end member 112b even after the protruding piece 124 of the vertical extension unit member 122 is inserted into the insertion hole 116a.
The configuration for attaching the vertical extension unit member 122 to the frame unit 110 is not limited as described in the present disclosure, and various configurations capable of firmly coupling the two components to each other may be included in the scope of the present disclosure.
In addition, the frame unit 110 may include at least one first end-first fixing pin 115a, which is installed on the frame-first end member 112c and protrudes upwards, and a first end-second fixing pin 115b, which has a different horizontal cross-section from that of the first end-first fixing pin 115a. Referring to
The inclination-forming fixing unit 120 may include: a pair of second end-side fixing pins 126 installed protruding upwardly from the vertical extension unit member 122, which extends upwardly; and a second end-central fixing pin 127 between the pair of second end-side fixing pins 126.
Here, a recessed groove 126a having a decreasing diameter may be formed at the bottom of each of the second end-side fixing pins 126.
As shown in
The frame unit 110 may include: the seating surface 114 extending horizontally inward in contact with an inner circumference of the seating space 113 toward the seating space 113, in which an electronic device having a width of w1 and a length h1 is placed; and a plurality of support protrusions 114a and 114b formed protruding from a periphery of the seating surface 114, wherein each of the plurality of support protrusions 114a and 114b may be spaced apart from each other on the seating surface 114.
A spacing between the support protrusion 114a and another support protrusion adjacent thereto toward the frame-first end member 112c is defined as h3, and a spacing between the support protrusion 114a and another support protrusion adjacent thereto toward the frame-second end member 112b is defined as h2. Here, h3 is formed to be greater than h2, and a folding recess 320 (see
In addition, the foldable electronic device to be placed in the seating space 113 for attachment of the display protector body 220 thereto may be placed in a way that the display unit thereof faces the +z direction in
Referring to
A folding recess 320 may be formed in a folding portion of a display unit 310 of the foldable electronic device 300. Here, the inclination-forming fixing unit 120 of the display protector attachment apparatus 100 may extend in parallel to the extending direction (x-axis direction in
As shown in
The cover member 130 may include pin through holes 134 (see
As shown in
In response thereto, as shown in
The first end-first fixing pin 115a of the display protector attachment apparatus 100 is inserted into the first extension unit-first through hole 226a of the protector film assembly 200, and thus, the first extension unit-first through hole 226a may have a complementary shape and diameter through which the first end-first fixing pin 115a may penetrate. The first end-second fixing pin 115b of the display protector attachment apparatus 100 is inserted into the first extension unit-second through hole 226b of the protector film assembly 200, and thus, the first extension unit-second through hole 226b may have a complementary shape and diameter through which the first end-second fixing pin 115b may penetrate.
As shown in
Moreover, the release film-second extension unit 214 may include, on the circumferential surface of the second extension unit-first through hole 224, an extension unit-first incision line 228 that is formed extending in a direction opposite to the direction in which the release film-first extension unit 216 is located. The extension unit-first incision line 228 may be formed in contact with the circumferential surface of the second extension unit-second through hole 227 from the circumferential surface of the second extension unit-first through hole 224. The extension unit-first incision line 228 may be opened by the second end-side fixing pin 126 and the second end-central fixing pin 127 that correspond to a tensile force applied to the body of the release film 220.
Referring to
As described above, because the horizontal cross-sections of the first end-first fixing pin 115a and the first end-second fixing pin 115b are different from each other, when the first extension unit-first through hole 116a→226a and the first extension unit-second through hole 116b→226b of the protector film assembly 200 correspond to the first end-first fixing pin 115a and the first end-second fixing pin 115b, respectively, the possibility of misinstallation may be prevented so that an operator may clearly recognize the corresponding relationship.
Similarly, based on that the second end-side fixing pins 126 and the second end-central fixing pin 127 of the display protector attachment apparatus 100 are each inserted into the second extension unit-first through hole 224 of the protector film assembly 200, the second extension unit-first through hole 224 may have a complementary size through which the second end-side fixing pins 126 and the second end-central fixing pin 127 may pass. Here, as shown in
As shown in
When the release film-second extension unit 214 of the protector film assembly 200 is arranged on the inclination-forming fixing unit 120, the side protrusion 121 may secure a certain height and space for coupling the release film-second extension unit 214. Also, when a tensile force is applied to the protector film assembly 200, the side protrusion 121 may maintain the tensile force applied to the protector assembly 200 constant.
The second end-side fixing pins 126 and the second end-central fixing pin 127 of the inclination-forming fixing unit 120 may each be inserted into the pin through holes 134 of the cover member 130, and thus, the pin through hole 134 may have a complementary diameter through which the second end-side fixing pins 126 and the second end-central fixing pin 127 may pass.
Considering the mutual coupling relationship, the interval d3 between the centers of the first end-first fixing pin 115a and the first end-second fixing pin 115b of the display protector attachment apparatus 100 may be set to be equal to the interval d5 between the centers of the first extension unit-first through hole 226a and the first extension unit-second through hole 226b of the release film in the protector film assembly 200. Similarly, the interval d0 between the pair of second end-side fixing pins 126 of the display protector attachment apparatus 100 may be set to be equal to the interval d4 between the two outermost second extension unit-second through holes 224 of the release film in the protector film assembly 200 and to the interval d2 between the two outermost pin through holes 134 of the cover member 130.
As shown in
Referring to
Moreover, the vertical extension member 122 of the inclination-forming fixing unit 120 in the display protector attachment apparatus 100 protrudes upwardly to a height of h6. The distance from the center of the first extension unit-first through hole 226a (i.e., the center of the first end-first fixing pin 115 of the frame unit 110) of the release film 210 in the protector film assembly 200 to the center of the second end-side fixing pin 126 (i.e., the center of the second extension unit-second through hole 224 of the release film-second extension unit 214) of the inclination-forming fixing unit 120 is defined as h5.
In this length relationship, the angle of inclination at which the protector film assembly 200 is placed on the display protector attachment apparatus 100 may be determined such that a tangent value of the corresponding tilt angle is h6/h5. When the angle of inclination is too large, the attachment of a protector to the surface of the foldable display unit of the foldable electronic device 300 by pressing the protector film assembly 200 from above is difficult due to the limitation of elasticity of the release film 210 itself, and the size of the inclination-forming fixing unit 120 increases, causing problems in packaging. On the other hand, when the angle of inclination is too small, the function of attaching a protector in close contact with the folding recess 320 may not be properly implemented and air bubbles are generated between the protector and the foldable display unit of the foldable electronic device.
The inventors of the present disclosure performed a number of experiments to obtain an optimal h6/h5 value. Considering the size of the foldable electronic device 300, h5 was set to 206.74 mm, and h6 was set to 20 mm, 30 mm, 40 mm, 60 mm, and 80 mm. Here, in a case where h6 was 20 mm and 30 mm, a protector and a foldable display unit of the foldable electronic device 300 may be in contact in advance when the protector is attached to the foldable display unit of the foldable electronic device 300, or due to a small binding angle between the protector and the foldable display unit of the foldable electronic device 300, air bubbles generated therebetween.
However, in a case where h6 is 40 mm, 60 mm, and 80 mm, a foldable display unit of the foldable electronic device 300 may not be in contact in advance when the protector is attached to the foldable display unit of the foldable electronic device 300 and air bubbles did not generate therebetween. That is, h6/h5 at which air bubbles are not generated between the protector and the foldable display unit of the foldable electronic device 300 is 40 mm/206.74 mm or more. In other words, the tangent value for the angle of inclination formed by the inclination-forming fixing unit 120 may be 40 mm/206.74 mm or more. Considering the size of packaging and the release film 210, the tangent value may preferably be 80 mm/206.74 mm or less.
On the other hand, in a case where h6 is 80 mm or more, the height of the inclination-forming fixing unit 120 increases, causing problems in packaging of the display protector attachment kit. Therefore, the tangent value (h6/h5) for the angle of inclination formed by the inclination-forming fixing unit 120 may more preferably be 40 mm/206.74 mm.
Referring to
The squeeze member 150 may include: a blade unit 156 configured to press the protector film assembly 200 against the foldable display unit of the foldable electronic device 300 and extend in a length corresponding to the width of the foldable display unit of the foldable electronic device; and a wing 154 extending from a side surface of the squeeze member 150, arranged at each of both ends of the blade unit 156 to extend from the side surface of the squeeze member 150, wherein a groove 158 having a width greater than a thickness (half of P1-P2 in
The wing 154 may be formed in a way that an end thereof extends further downward by t1 than the blade unit 156. Therefore, when a user holds a handle 152 of the squeeze member 150 with the hand and slides the squeeze member 150 while pressing the squeeze member 150 toward the upper surface of the protector film assembly 200 (i.e., the upper surface of the release film 210), as shown in
The handle 152 may be covered with a non-woven fabric not only to prevent slipperiness, but also to be in close contact with the edge of the display unit when sliding the display unit using the handle 152.
A finger seating hole 151 may be provided under the handle 152 to accommodate the tip of the fingers of an operator. Intervals and positions between the finger seating holes 151 may be arranged considering ergonomics. When the fingers of an operator are inserted into the finger seating holes 151, the operator may guide the fingers upon the attachment of the protector film assembly 200, and the force applied by the squeeze member 150 may be distributed.
As described above with reference to
The extension unit-first incision line 228 may be formed between the second extension unit-first through hole 224 and the second extension unit-second through hole 227. The length of the extension unit-first incision line 228 may be set considering the length at which the release film 210 is stretched when the protector film assembly 200 is attached to the foldable display unit of the foldable electronic device, that is, the electronic device 300, using the squeeze member 150 considering the elongation rate of the release film 210.
Therefore, as shown in
As an example of a foldable electronic device having a foldable display unit that folds from side to side, a smartphone manufactured by Samsung Electronics (the Galaxy Fold®) may be considered. A folding line of the foldable display unit that folds from side to side may extend in a vertical direction of the display unit.
The configuration that an inclination-forming fixing unit 120′ extends in parallel to an extension direction of a folding recess 320′ of a foldable electronic device having a foldable display unit that folds from side to side is the same as in the case of the embodiments shown in
The size of a seating space 113′ may also be formed corresponding depending on the width and height of the external appearance of the foldable electronic device. In a foldable electronic device having a foldable display unit that folds from side to side, the length of the folding recess 320′ may be set to be larger than that of the embodiment shown in
Referring to
A protector attachment kit for a foldable electronic device having a foldable display according to an embodiment of the present disclosure may include, in addition to the display protector attachment apparatus 100, the protector film assembly 200 and the squeeze member 150.
First, a user of the display protector attachment kit may assemble the attachment device 110 by coupling the inclination-forming fixing unit 120 to the frame part 110 of the attachment device 100 (ST1). On such an assembled attachment apparatus, a foldable electronic device, for example, a foldable phone, to which a protector is attached may be placed (ST2). Next, the protector film assembly 200 may be located inclinedly to the display protector attachment apparatus 100 and fixed therewith (ST3), and the cover member 130 may cover and fix the release film-second extension unit of the protector film assembly 200 fixed on the inclination-forming fixing unit of the display protector attachment apparatus (ST4). Then, when the squeeze member 150 is pressed with a force while sliding on the upper surface of the protector film assembly 200 (ST5), the protector may be closely attached to the flat portion of the foldable display unit of the foldable electronic device as well as the folding recess 320. Afterwards, when the cover member is released and the release film is removed, the process of attaching the protector to the electronic device is completed.
The disclosed embodiments are to be considered in a descriptive point of view rather than a restrictive sense. The scope of the present disclosure is indicated in the claims rather than the above description, and differences within the scope equivalent thereto should be construed as being included in the disclosure. In the case of a term whose meaning is not specifically defined in the present disclosure, it should be interpreted broadly in its general meaning, and should be interpreted as including other terms in an equivalent range.
According to the one or more embodiments, a display protector attachment apparatus for a foldable electronic device including a foldable display unit and a display protector attachment kit may exhibit the following effects.
First, a display protector may be aligned and attached at an accurate position of a display unit of a foldable electronic device including a foldable display unit.
Second, a display protector for a foldable electronic device of which a display unit is foldable may be attached in close contact with a recess of a folding line of the display unit.
Third, when a release film of a protector film assembly is pulled in the process of attaching a display protector to a display unit of a foldable electronic device, the formation of wavy curves or wrinkles on the release film may be prevented, thereby improving the accuracy of the protector attachment.
Fourth, when a release film of a protector film assembly is pulled in the process of attaching a display protector to a display unit of a foldable electronic device, an incision line may be formed in the extension direction of the release film, thereby exhibiting a predetermined elongation effect of the release film while minimizing the deformation of the release film body.
Fifth, because a display protector attachment kit according to an embodiment of the present disclosure includes a squeeze member for closely attaching a protector film assembly to a display unit of a foldable electronic device, the protector may be closely attached without a gap even to a recess of a folding line formed on a surface of a foldable display unit of a foldable electronic device.
Sixth, because a squeeze member of the display protector attachment kit of the present disclosure includes wings on both sides to slide along the width of a display unit of an electronic device, there is no need to accurately align the squeeze member when the squeeze member is pressed against the display unit.
It should be understood that embodiments described herein should be considered in a descriptive sense only and not for purposes of limitation. Descriptions of features or aspects within each embodiment should typically be considered as available for other similar features or aspects in other embodiments. While one or more embodiments have been described with reference to the figures, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the following claims.
