Description

Technical Field

[0001] The present invention relates to a display device, and more particularly to a rotatable display device. Background Technology

[0002] In recent years, the monitor market has flourished, with widespread applications in various electronic devices. This market growth is driven by innovative technologies. Monitors, designed for diverse usage scenarios, may be rotated to be positioned vertically or horizontally. When a monitor is rotated from horizontal to vertical, the optical films can sag or shift due to ineffective positioning, resulting in poor optical quality. Furthermore, since high-end monitors particularly require uniform optical brightness, effectively positioning the optical films has become a key industry concern. Summary of the Invention

[0003] In view of this, in one embodiment, a display device is provided, including a frame and an optical film. The frame includes a base, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. The first sidewall, the second sidewall, the third sidewall, and the fourth sidewall are disposed perpendicular to the base and arranged perpendicularly to each other in sequence to form an accommodating space. The first sidewall and the third sidewall each have a first positioning structure, and the two ends of the second sidewall and the fourth sidewall are bent toward the accommodating space to form a plurality of second positioning structures. The optical film is disposed in the accommodating space. The optical film includes a body, a plurality of first positioning elements, and a plurality of second positioning elements. The body has a first side, a second side, a third side, and a fourth side connected in sequence. The plurality of first positioning elements are respectively disposed on the first side and the third side, and each first positioning structure is respectively inserted through a first positioning element. The plurality of second positioning elements are respectively disposed at the four corners of the body. The plurality of second positioning elements extend along a direction parallel to the first side or the third side, and each of the plurality of second positioning elements corresponds to a second positioning structure.

[0004] In some embodiments, each first positioning member includes a limiting structure, the limiting structure including an open end and a closed end opposite to each other, the open end being located at the edge of a first side or a third side.

[0005] In some embodiments, there is a gap between the edge of each closed end and the corresponding first positioning structure passing through the first positioning member.

[0006] In some embodiments, each of the first positioning members further includes a protrusion extending in a direction away from the receiving space, and the limiting structure is located on the protrusion.

[0007] In some embodiments, the display device further includes two storage portions, one of which is formed between a second sidewall and a plurality of second positioning structures formed by bending the second sidewall toward the receiving space, and the other of which is formed between a fourth sidewall and a plurality of second positioning structures formed by bending the fourth sidewall toward the receiving space.

[0008] In some embodiments, the display device further includes two light-emitting modules, each housed within a second housing.

[0009] In some embodiments, each second positioning member has a first extension and a second extension, the first extension and the second extension extending in a direction parallel to the first side or the third side, and each second positioning structure is located between the first extension and the second extension of the corresponding second positioning member.

[0010] In summary, some embodiments provide a display device in which the optical film can be positioned by multiple second positioning members located at the four corners of the optical film against the second positioning structure. When the display device is rotated 90 degrees, the optical film can also be positioned by multiple first positioning structures located on the first and third sidewalls corresponding to the first positioning members. Therefore, regardless of whether the display device is rotated vertically or horizontally, the optical film can be positioned, thereby avoiding the problem of poor optical quality caused by the optical film sagging or significant displacement due to insufficient support or poor support method.

[0011] Furthermore, by bending the two ends of the second and fourth side walls of the frame towards the accommodating space to form multiple second positioning structures, these structures can be formed simultaneously during frame molding without the need for additional components, serving as limiting and fixing mechanisms. Additionally, by using the bending direction, the positioning structures can be formed without affecting the thickness specifications of the display device.

[0058] Please refer to Figure 1 and Figure 2 As shown, Figure 1 An exploded perspective view of a display device according to a first embodiment. Figure 2 This is a partial top view of a display device according to a first embodiment. Figure 2 According to Figure 1 The top view of the display device is omitted after rotating the display device 90 degrees. A display device 1 mainly includes a frame 10 and an optical film 20.

[0059] like Figure 1 As shown, the frame 10 includes a base 11, a first sidewall 111, a second sidewall 112, a third sidewall 113, and a fourth sidewall 114. Here, the first sidewall 111, second sidewall 112, third sidewall 113, and fourth sidewall 114 are perpendicular to the base 11 and arranged sequentially perpendicular to each other to form an accommodating space Q. An optical diaphragm 20 can be disposed within the accommodating space Q. The optical diaphragm 20 includes a body 21, a plurality of first positioning elements 22, and a plurality of second positioning elements 23, as shown in the diagram. Figure 2 As shown, Figure 2 The illustration shows an optical film 20 including two first positioning elements 22 and four second positioning elements 23.

[0060] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, Figure 3 for Figure 2 A magnified view of part A. Figure 4 for Figure 2 A partially enlarged schematic diagram of point A after rotating 90 degrees. The first sidewall 111 and the third sidewall 113 each have a first positioning structure 115. In some embodiments, the first positioning structure 115 is disposed perpendicular to the base 11, and the first positioning structure 115 is generally columnar or generally conical (gradually tapering from the upper surface of the base 11 toward the direction away from the base 11), and can be correspondingly inserted into the first positioning member 22 disposed on the optical diaphragm 20.

[0061] Please refer to Figure 2 , Figure 5 and Figure 6 As shown, Figure 5 for Figure 2 A magnified view of point B from another perspective. Figure 6 for Figure 2 A partially enlarged schematic diagram from another perspective at point C. The two ends of the second sidewall 112 and the fourth sidewall 114 are bent toward the accommodating space Q to form multiple second positioning structures 116, as shown... Figure 2 As shown, Figure 2 The illustration shows four second positioning structures 116, but the number of second positioning structures 116 is not limited. In some embodiments, the two ends of the second sidewall 112 and the fourth sidewall 114 are not connected to the adjacent first sidewall 111 and third sidewall 113. Therefore, a locking space is formed between the second positioning structure 116 and the adjacent first sidewall 111 or third sidewall 113. This allows for... Figure 6 As can be seen, the second positioning member 23 of the optical diaphragm 20 can be accommodated in the locking space, and the inner side 23a of the second positioning member 23 abuts against the surface 116a of the corresponding second positioning structure 116 (e.g., Figure 5 (As shown).

[0062] Please refer to Figure 1 and Figure 2 As shown, the optical diaphragm 20 includes a body 21, a plurality of first positioning elements 22, and a plurality of second positioning elements 23. The body 21 of the optical diaphragm 20 has a first side 211, a second side 212, a third side 213, and a fourth side 214 connected in sequence. Figure 2The invention uses two first positioning elements 22 as an example, but the number of first positioning elements 22 is not limited. The two first positioning elements 22 are respectively disposed on the first side 211 and the third side 213, as shown below. Figure 3 and Figure 4 As shown, each first positioning structure 115 is respectively inserted into a first positioning member 22. Therefore, by Figure 4 As can be seen, display device 1 is horizontally positioned (or for example...) Figure 1 When the optical film 20 is placed in the correct orientation, the inner side 22a of the first positioning member 22 abuts against the first positioning structure 115 to provide symmetrical support for the optical film 20. This avoids the problem of the optical film 20 sagging or shifting due to insufficient support or poor support method, thus affecting optical quality.

[0063] Please refer to Figure 2 , Figure 5 and Figure 6 As shown. Multiple second positioning elements 23 of the optical film 20 are respectively disposed at the four corners of the body 21. Here, four second positioning elements 23 are used as an example for illustration; the present invention does not limit the number of second positioning elements 23. Each second positioning element 23 extends along a direction parallel to the first side 211 or the third side 213, and each of the four second positioning elements 23 corresponds to one second positioning structure 116. Figure 5 and Figure 6 As shown, the second positioning member 23 is accommodated in the locking space formed between the second positioning structure 116 and the adjacent first side wall 111 or third side wall 113, and the second positioning member 23 has an inner side 23a parallel to the first side 211 or third side wall 213. When the display device 1 is rotated to a vertical orientation (such as from...), Figure 1 The horizontal arrangement shown is rotated to the position shown. Figure 2 When the display device 1 is placed in a vertical orientation (as shown), the inner side 23a abuts against the second positioning structure 116. Therefore, when the display device 1 is placed in a vertical orientation, it is positioned on the second positioning structure 116 by the second positioning member 23, which can avoid the optical film 20 from sagging or shifting significantly due to insufficient support or poor support method, thus avoiding the problem of poor optical quality.

[0064] Therefore, the display device 1 is placed in a straight line (e.g.) Figure 2 When the optical film 20 is positioned in the direction shown, it can be supported and positioned by the second positioning structure 116 abutting against the second positioning member 23 located at the four corners of the optical film 20. When the display device 1 is rotated 90 degrees and placed horizontally (as shown...), the optical film 20 can be supported and positioned. Figure 1 When the direction is (e.g.), the positioning optical diaphragm 20 can be supported by two first positioning structures 115 located on the first sidewall 111 and the third sidewall 113 respectively corresponding to the first positioning member 22, which are respectively inserted through the first positioning structure 22. Figure 4(As shown). Therefore, regardless of whether the display device 1 is rotated to a vertical or horizontal orientation, the optical film 20 can be positioned, thereby avoiding the problem of poor optical quality caused by the optical film 20 sagging or large displacement due to insufficient support or poor support method. In addition, the two ends of the second sidewall 112 and the fourth sidewall 114 of the frame 10 are bent toward the accommodating space Q to form the second positioning structure 116. This can be formed simultaneously during the molding of the frame 10 without the need for additional components, serving as a limiting and fixing mechanism. Furthermore, by using the bending direction, the positioning structure can be formed without affecting the thickness specifications of the display device 1.

[0065] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, each first positioning member 22 may include a limiting structure 221. The limiting structure 221 includes an open end 221a and a closed end 221b, and the open end 221a is located on the edge of the first side 211 or the third side 213. In other words, if the first positioning member 22 is located on the first side 211, the open end 221a is located on the edge of the first side 211, so that the limiting structure 221 forms an opening towards the first side 211. And if the first positioning member 22 is located on the third side 213, the open end 221a is located on the edge of the third side 213, so that the limiting structure 221 forms an opening towards the third side 213. Here, the limiting structure 221 may be U-shaped (e.g., Figure 3 and 4 (As shown), V-shaped and other shapes with opposite open ends 221a and closed ends 221b.

[0066] Thus, when the frame 10 or the optical diaphragm 20 expands due to heat, the opening end 221a can also provide expansion and contraction space, preventing the first positioning structure 115 from squeezing the first positioning member 22, thereby preventing the optical diaphragm 20 from being twisted or deformed due to force.

[0067] Furthermore, during the process of the display device 1 turning and moving (such as from...) Figure 1 The horizontal arrangement shown is rotated to the position shown. Figure 2 During the straight placement process shown, the arc-shaped structure design of the closed end 221b ensures that the display device 1 can abut against the first positioning structure 115 regardless of the angle of rotation, and also avoids the problem of poor optical quality caused by excessive displacement of the optical film 20.

[0068] Please refer to Figure 4As shown, there is a gap W between the edge of the closed end 221b and the first positioning structure 115 correspondingly inserted through the first positioning member 22. This gap W provides expansion and contraction space to prevent the first positioning structure 115 from squeezing the first positioning member 22, thereby avoiding twisting or deformation of the optical film 20 due to force. In addition, the gap W also provides displacement space during the rotation and movement of the display device 1.

[0069] Please refer to Figure 3 As shown, each first positioning member 22 may further include a protrusion 222 extending in a direction away from the accommodating space Q, and the limiting structure 221 is located at the protrusion 222. Figure 3 As shown, the first sidewall 111 is not continuously arranged along the side of the base 11, and a receiving opening 111a is formed at the discontinuity of the first sidewall 111. The first positioning structure 115 and the first positioning member 22 are located in the receiving opening 111a. In other words, the first positioning structure 115 and the first positioning member 22 are respectively the first sidewall 111 on both sides. Here, the structure of the third sidewall 113 is the same as that of the first sidewall 111, and will not be described again. In this way, by placing the first positioning structure 115 and the first positioning member 22 in the receiving opening 111a, the width of the frame of the display device 1 on the first sidewall 211 and the third sidewall 213 can be reduced, and the display area of ​​the display device 1 can be increased.

[0070] Furthermore, when the frame 10 or the optical diaphragm 20 expands due to heat, since only the second positioning member 23 abuts against the second positioning structure 116 through its inner side 23a (only one inner side 23a of the second positioning member 23 abuts against the second positioning structure 116), the corner distortion and deformation of the optical diaphragm 20 caused by the existing positioning method of positioning posts passing through the four corners of the optical diaphragm 20 can be avoided.

[0071] Please refer to Figure 2 and Figure 7 As shown, Figure 7 for Figure 2 A partially enlarged schematic diagram at point C. In some embodiments, the display device 1 further includes a plurality of storage portions 30, such as... Figure 7 Taking two storage sections 30 as examples, one storage section 30 is formed between the fourth side wall 114 and the second positioning structure 116 formed by bending the fourth side wall 114 toward the receiving space Q, while the other storage section 30 is formed between the second side wall 112 and the second positioning structure 116 formed by bending the second side wall 112 toward the receiving space Q. Their structures are symmetrical. Figure 8 As shown. Thus, the second positioning structure 116 not only functions to position the optical film 20 and the frame 10, but can also form a storage part 30 together with the second side wall 112 or the fourth side wall 114, which helps to achieve a thinner design for the display device 1.

[0072] Please refer to Figure 2 and Figure 7 As shown, in some embodiments, the display device 1 further includes a plurality of light-emitting modules 40 housed within the housing 30. Thus, the display device 1 does not require an additional structure to house the light-emitting modules 40, which contributes to the lightweight and thin design of the display device 1.

[0073] Please refer to Figure 8 and Figure 9 As shown, Figure 8 A partial top view of a display device according to a second embodiment. Figure 9 for Figure 8 A partially enlarged schematic diagram of point D from another perspective. It should be noted that in this embodiment, the parts that are the same as in the first embodiment will be marked with the same component symbols, and the same components and structures will not be described again.

[0074] In this embodiment, each second positioning member 23 has a first extension 231 and a second extension 232. The first extension 231 and the second extension 232 extend in a direction parallel to the first side 211 or the third side 213. Each second positioning structure 116 is located between the first extension 231 and the second extension 232 of the corresponding second positioning member 23.

[0075] Here, compared to the display device 1 in the first embodiment, it is rotated to a vertical orientation (as in the first embodiment). Figure 1 The horizontal arrangement shown is rotated to the position shown. Figure 8 When the display device 1 is placed in a vertical orientation (as shown), only the inner side 23a of the second positioning member 23 located at the top abuts against the second positioning structure 116 to provide support for the optical film 20. In this embodiment, when the display device 1 is placed in a vertical orientation (as shown), Figure 8 When the display device 1 is rotated 180 degrees, the inner sides 231a of the first extension 231 located at the upper left and right corners abut against the second positioning structure 116, and the inner sides 232a of the second extension 232 located at the lower left and right corners also abut against the second positioning structure 116. This allows the optical film 20 to be supported by the upper first extension 231 and the lower second extension 232 respectively, preventing the supporting force from being concentrated on the upper two first extensions 231, thus avoiding deformation or breakage of the upper second positioning member 23 over time. Similarly, the same effect is achieved when the display device 1 is rotated 180 degrees, i.e., the inner sides 231a of the first extension 231 located at the upper left and right corners abut against the second positioning structure 116, and the inner sides 232a of the second extension 232 located at the lower left and right corners also abut against the second positioning structure 116. In other words, when the display device 1 is placed vertically, the first extension 231 and the second extension 232 will simultaneously support the optical film 20. This can prevent the second positioning member 23 located above from being easily deformed or broken, thus increasing the service life of the display device 1.

[0076] Please refer to Figure 8 and Figure 10 As shown, Figure 10 for Figure 8 A partially enlarged schematic diagram of point E from another perspective. In this embodiment, the first positioning member 22 may also not include the protrusion 222 (e.g., Figure 3 The protrusion 222 shown makes the closed end 221b of the limiting structure 221 located inside the first side 211. In other words, the closed end 221b of the limiting structure 221 is located within the accommodating space Q.

[0077] It should be noted that the first positioning member 22 in this example does not include the protrusion 222 for illustrative purposes only and is not intended to be limiting. The first positioning member 22 may also include the protrusion 222. Furthermore, the first positioning member 22 in the aforementioned first embodiment may also not include the protrusion 222.

[0078] In summary, the display device 1 is placed in a straight line (e.g., Figure 2 and Figure 8 When the optical film 20 is positioned in the direction shown, it can be supported and positioned by multiple second positioning members 23 located at the four corners of the optical film 20 abutting against the second positioning structure 116. When the display device 1 is rotated 90 degrees and placed horizontally (as shown...), the optical film 20 can be supported and positioned. Figure 1 When the first positioning structure 115 located on the first sidewall 111 and the third sidewall 113 respectively passes through the first positioning member 22, the positioning optical film 20 can be supported (e.g., in the direction of the first positioning structure 115 located on the first sidewall 111 and the third sidewall 113 respectively, and the first positioning member 22 is respectively inserted through it). Figure 4 (As shown). Therefore, regardless of whether the display device 1 is rotated to a vertical or horizontal orientation, the optical film 20 can be positioned, thereby avoiding the problem of poor optical quality caused by the optical film 20 sagging or large displacement due to insufficient support or poor support method. In addition, the two ends of the second sidewall 112 and the fourth sidewall 114 of the frame 10 are bent toward the accommodating space Q to form a plurality of second positioning structures 116, which can be formed simultaneously during the molding of the frame 10 without the need for additional components, and serve as a limiting fixation. Furthermore, by using the bending direction, the positioning structure can be formed without affecting the thickness specification of the display device 1.

[0079] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the claims of the present invention.
