Description

Technical Field

[0001] This invention relates to a display device. More specifically, this invention relates to a display device having a locking member and a locking groove. Background Technology

[0002] With the widespread adoption of display devices, industrial design (ID) for display device appearance is also booming. However, current display device assembly often uses screws to fasten modules or components. Excessive screw fastening of core modules or components hinders assembly with different exterior or support components to achieve various industrial designs. Furthermore, excessive screw fastening increases the manpower and time required for assembly, thereby raising manufacturing costs and time consumption. Therefore, to reduce costs and accelerate assembly, while enabling the same core modules or components to be widely compatible with different industrial designs, it is necessary to develop alternative assembly and interlocking methods or structures. Summary of the Invention

[0003] To address the aforementioned problems, an embodiment of the present invention discloses a display device comprising: a backlight module having a back plate, wherein the back plate has a back surface opposite to the light-emitting side of the backlight module; a frame at least partially surrounding the backlight module and having a support portion stacked on the back surface; at least one engaging member, each disposed on the back surface, and having a stop portion and a connecting portion connecting the stop portion and the back surface; and at least one engaging groove, each formed on the support portion through the support portion of the frame, and having an engaging hole and at least a connecting groove communicating with the engaging hole. The width of the stop portion in a first direction substantially parallel to the back surface is greater than the width of the engaging hole in the first direction, and the width of the connecting portion in the first direction is less than the width of the engaging hole in the first direction. The engaging members are detachably engaged with the engaging holes, thereby positioning and engaging the back plate and the frame with each other.

[0004] The display devices according to various embodiments of the present invention can reduce the cost or time required for assembly while maintaining the stability and reliability of the assembly structure. Furthermore, the display devices according to various embodiments of the present invention can assist in snap-fit ​​assembly by providing at least one snap-fit ​​member and at least one corresponding snap-fit ​​slot, thereby reducing the number of screws required while maintaining assembly strength or quality, and thus increasing the efficiency of the assembly process. In addition, based on the selectively configurable and usable snap-fit ​​structure, the same core component, such as the same backlight module, can be more flexibly assembled with various appearance parts or support parts, such as frames or back covers, thereby enabling the realization of display devices with different industrial designs by assembling fixed or predetermined core components while reducing technology development time and costs.

[0107] Various embodiments will be described below, and those skilled in the art should readily understand the spirit and principles of the invention by referring to the description and accompanying drawings. However, while specific embodiments will be described in detail herein, these embodiments are merely illustrative and are not intended to be limiting or exhaustive in any respect. Therefore, various changes and modifications to the invention will be readily apparent and easily achievable by those skilled in the art without departing from the spirit and principles of the invention. Furthermore, those skilled in the art will understand that the dimensions or relative dimensions of the components in the accompanying drawings may be exaggerated or adjusted for clarity or illustration.

[0108] An embodiment of the present invention discloses a display device 10, which includes at least a backlight module 200 and a frame 300 at least partially surrounding the backlight module 200. Additionally, the display device 10 may further include a display module 100 and a back cover 400. More specifically, the display device 10 may sequentially include a stacked display module 100, a backlight module 200, a frame 300, and a back cover 400, but the present invention is not limited thereto.

[0109] As described above, the backlight module 10 of the display device 10 may have a back plate 210, which may have a back surface S2 opposite to the light-emitting side LS of the backlight module 200 and a front surface S1 opposite to the back surface S2. Additionally, the frame 300 may have at least one support portion 310 stacked on the back surface S2 to support the back plate 210. The support portion 310 may have a supporting surface S3 facing the back plate 210 and a reverse surface S4 opposite to the supporting surface S3 and facing away from the back plate 210. Furthermore, according to different embodiments, the frame 300 may further have side frame portions 320 surrounding the side of the backlight module 200 and / or a front frame portion 330 covering and protecting the backlight module 200 or display module 100 on the light-emitting side LS, and the present invention is not limited to the specific form of the frame 300 shown here. For example, according to some embodiments, the frame 300 may only include the support portion 310 stacked on the back surface S2 of the back plate 210.

[0110] Continuing from the above, according to an embodiment of the present invention, the display device 10 may include at least one engaging structure M. The engaging structure M may include an engaging member 500 disposed on the back surface S2 of the back plate 210, and an engaging groove 600 formed on the support portion 310 penetrating the frame 300. The engaging member 500 may be integrally formed with the back plate 210 by injection molding; it may be separately fastened to the back plate 210 by stepped screws; or it may be formed by rivets to the back plate 210, etc., and the means or forms of providing the engaging member 500 applicable to the present invention are not limited to these. As described above, in the display device 10, the frame 300 and the back plate 210 can be assembled by engaging with at least one engaging member 500 and at least one engaging groove 600, thereby further enhancing the assembly stability or accuracy.

[0111] Reference Figure 1 According to this embodiment, the snap-fit ​​structure M can be disposed on the back panel 210 without compromising the integrity of the back panel 210, and can be disposed on frames 300 with various appearances or structures (e.g., frames 300 with appearances such as frameless, borderless, narrow frame, frameless, etc.). Furthermore, the frame 300 disposed with the corresponding snap-fit ​​structure M can be further assembled with components with different appearances or structures, such as the back cover 400, to achieve different industrial designs. Therefore, the snap-fit ​​structure M according to various embodiments of the present invention can have a high degree of commonality for different industrial designs, and the various forms of industrial designs to which the snap-fit ​​structure M is applicable are not limited to the forms specifically illustrated herein.

[0112] In the following description, further reference will be made to other accompanying drawings to illustrate specific examples of different examples of the engaging structures according to various embodiments of the present invention.

[0113] Following on, please include Figure 1 Reference Figures 2 to 4BThe document details an engagement structure M1 according to an embodiment of the present invention. Figure 2 This shows the state where the engaging structure M1 is not yet assembled, and Figure 3 The assembly state of the locking mechanism M1 is shown. Additionally, Figure 4A Show along Figure 3 A cross-sectional schematic diagram of the X1-X1' section line of the engaging structure M1, and Figure 4B Show Figure 3 A cross-sectional schematic diagram of the Y1-Y1' section line of the locking structure M1.

[0114] Specifically, according to this embodiment, the engaging member 500 on the back plate 210 may have a stop portion 510 and a connecting portion 520 connecting the stop portion 510 and the back surface S2. Additionally, the engaging groove 600 on the frame 300 may have an engaging hole 610 and at least a portion of a connecting groove 620 communicating with the engaging hole 610. As described above, the width W1 of the stop portion 510 in a first direction D1 substantially parallel to the back surface S2 may be greater than the width B1 of the engaging hole 610 in the first direction D1. Furthermore, the width W2 of the connecting portion 520 in the first direction D1 is less than the width B1 of the engaging hole 610 in the first direction D1. Therefore, according to this embodiment, the engaging member 500 on the back plate 210 is detachably positioned and engaged with the engaging hole 610, such that the stop portion 510 is relatively engaged with the engaging hole 610, thereby positioning and engaging the back plate 210 and the frame 300 with each other.

[0115] In the engaging structure M1, the engaging groove 600 may include an inlet 630, a connecting groove 620, and an engaging hole 610. The inlet 630 is configured to allow the engaging member 500 to pass through the frame 300, and the connecting groove 620 connects the inlet 630 and the engaging hole 610. In the first direction D1, the width B1 of the engaging hole 610 may be smaller than the width B3 of the inlet 630. Based on this width difference, according to this embodiment, the engaging member 500 can first enter through the wider inlet 630 and pass through the frame 300, and then be moved along the connecting groove 620 to the intended engaging hole 610, thereby positioning and engaging the frame 300 and the back plate 210.

[0116] According to this embodiment, the connecting groove 620 of the engaging structure M1 can extend along a second direction D2 substantially parallel to the back surface S2. For example, the connecting groove 620 of the engaging structure M1 can extend along a second direction D2 substantially parallel to the back surface S2 and perpendicular to the first direction D1. As described above, in some embodiments, in the first direction D1, the width B2 of the connecting groove 620 of the engaging structure M1 extending from the inlet 630 along the second direction D2 toward the engaging hole 610 can be gradually reduced. This assists the engaging member 500 in gradually transitioning from the wider inlet 630 to the engaging hole 610, and through the interactive movement of the engaging member 500 contacting and pressing against the sidewalls of the engaging groove 600 on opposite sides, small-amplitude, gradual shifting can correct possible misalignment or deformation during the assembly of the frame 300 and the back plate 210. Therefore, the accuracy of the final assembled product can be further improved.

[0117] Following on, such as Figure 3 As shown, when they are engaged, the stop portion 510 of the engaging member 500 can protrude beyond the engaging hole 610 and away from the back plate 210, while the connecting portion 520 of the engaging member 500 can pass through the engaging hole 610 and be disposed in the engaging hole 610 to connect the stop portion 510 and the back surface S2 of the back plate 210.

[0118] Furthermore, according to this embodiment, the back surface S2 of the back plate 210 can be recessed to form an inner groove U1, and the engaging member 500 can be disposed in the inner groove U1 and protrude from the back surface S2. Conversely, the reverse side S4 of the frame 300 facing away from the back plate 210 can be recessed to form an inner recess T1, and the inner recess T1 protrudes from the supporting surface S3 of the frame 300 facing the back plate 210. Continuing on, the engaging groove 600 is disposed in the inner recess T1, and the area of ​​the inner recess T1 substantially parallel to the back surface S2 is smaller than the area of ​​the inner groove U1 parallel to the back surface S2. Referring to this structure… Figure 4A and Figure 4B When the engaging component 500 engages with the engaging groove 600, the recessed portion T1 of the frame 300 can be inserted into and housed within the recessed groove U1. This reduces the space occupied by the engaging component 500 and its corresponding engaging mechanism protruding from the back panel 210's back surface S2. Furthermore, the correspondence between the recessed portion T1 and the recessed groove U1 further emphasizes the intended alignment, allowing for more intuitive alignment during assembly.

[0119] As described above, in this embodiment, to reduce or avoid the latching member 500 protruding relative to the reverse side S4 of the frame 300, the height H of the latching member 500 protruding from the inner groove U1 can be reduced. For example, the height H of the latching member 500 protruding from the inner groove U1 is less than or equal to the depth TH of the inner groove U1 recessed from the back side S2. Thus, the latching member 500 can be completely housed within the inner groove U1. However, this is merely an example, and the invention is not limited thereto.

[0120] Specific reference Figure 4B When it is intended that the recessed portion T1 of the frame 300 is inserted into and housed within the recessed groove U1, since the insertion of the recessed portion T1 into the recessed groove U1 causes the engaging member 500 to pass through the inlet 630 first, and the engaging member 500 needs to be moved to the engaging hole along the connecting groove 620, in the second direction D2, the sum of the length E of the recessed portion T1 and the length E1 of the connecting groove 620 can be less than the length L of the recessed groove U1. Therefore, when the recessed portion T1 is first inserted into the recessed groove U1 and moves relative to the connecting groove 620 extending along the second direction D2, the recessed portion T1 can not exceed the range of the recessed groove U1. That is, the recessed portion T1 can move within the recessed groove U1 along the second direction D2.

[0121] As described above, in this embodiment, the recess U1 may have opposite first endpoint P1 and second endpoint P2 along the second direction D2. Specifically, in the second direction D2, the distance d1 from the engaging member 500 to the first endpoint P1 or the distance d2 from the engaging member 500 to the second endpoint P2, or both, may be at least greater than the length E1 of the connecting groove 620. Further, according to some embodiments, the distance d1 from the engaging member 500 to the first endpoint P1 or the distance d2 from the engaging member 500 to the second endpoint P2, or both, may even be greater than the length E of the recess T1.

[0122] For example, according to some embodiments, one of the distances d1 from the engaging member 500 to the first endpoint P1 or d2 from the engaging member 500 to the second endpoint P2 may be at least greater than the length E1 of the connecting groove 620, and the other may be at least greater than the length E of the recess T1. Therefore, if the engaging member 500 first passes through the frame 300 via the inlet 630 and causes the recess T1 to be inserted into the recess U1, the distance from the engaging member 500 to one of the endpoints (the first endpoint P1 or the second endpoint P2) is at least sufficient to accommodate the recess T1 containing the connecting groove 620. Then, as the engaging member 500 subsequently moves from the inlet 630 to the engaging hole 610, the distance from the engaging member 500 to the other endpoint (the second endpoint P2 or the first endpoint P1) is also at least sufficient to provide space for relative movement of the recess T1 and the recess U1 along the connecting groove 620.

[0123] Next, please refer to Figures 5 to 7CThe engaging structure M2 according to another embodiment of the present invention is shown in detail. Continuing from the above, Figure 5 This shows the state where the engaging structure M2 is not yet assembled, and Figure 6 The assembly state of the locking mechanism M2 is shown. Additionally, Figure 7A Show along Figure 6 A cross-sectional diagram of the X2-X2' section line of the locking structure M2. Figure 7B Show along Figure 6 A cross-sectional schematic diagram of the Y2-Y2' section line of the engaging structure M2, and Figure 7C Show along Figure 6 A cross-sectional schematic diagram of the Z2-Z2' section line of the locking structure M2.

[0124] As described above, according to this embodiment, the engaging member 500 on the back plate 210 may also have a stop portion 510 and a connecting portion 520 connecting the stop portion 510 and the back surface S2, and may be formed in the inner groove U1. Furthermore, the engaging groove 600 on the frame 300 may have an engaging hole 610 and at least a portion of a connecting groove 620 communicating with the engaging hole 610. Following this, the following text will mainly describe the differences between the engaging structure M2 and the aforementioned engaging structure M1, and details that are the same as or similar to the engaging structure M1 will not be repeated here.

[0125] Specifically, the engaging structure M2 according to this embodiment may not have a recessed portion T1 corresponding to the inner groove U1. More specifically, according to this embodiment, as... Figures 7A to 7C As shown, the height H of the engaging member 500 protruding from the inner groove U1 can actually be greater than the depth TH of the inner groove U1 recessed from the back surface S2. Therefore, the engaging member 500 can protrude from the inner groove U1 onto the back surface S2 and is positioned in the reserved unit installation space behind the reverse side S4 of the frame 300. Thus, with space available for the engaging member 500 to protrude, the manufacturing process for the recessed portion T1 can be reduced according to this embodiment. As described above, the desired engaging structure can be selected based on the available installation space.

[0126] Furthermore, according to this embodiment, the shape of the inlet 630 may differ from the shape of the inlet 630 of the engaging structure M1. For example, the engaging structure M1 may have an elliptical strip-shaped inlet, while the engaging structure M2 of this embodiment may have a circular inlet. Further, the connecting groove 620 may not have a width B2 that tapers from the inlet 630 along the second direction D2 toward the engaging hole 610. Thus, according to this embodiment, the engaging groove 600 can be more simply provided, thereby reducing the cost of providing the engaging structure M2 and simplifying the manufacturing process of the engaging structure M2. In conclusion, according to different embodiments, the shape and width of the engaging groove 600 can be freely adjusted according to requirements, and the specific forms shown herein are merely examples.

[0127] Next, refer to Figures 8 to 10C The engaging structure M3 according to an embodiment of the present invention is shown in detail. Continuing from the above, Figure 8 This shows the engagement structure M3 in an unassembled state, and Figure 9 The assembly state of the locking mechanism M3 is shown. Additionally, Figure 10A Show along Figure 9 A cross-sectional schematic diagram of the X3-X3' section line of the locking structure M3. Figure 10B Show along Figure 9 A cross-sectional schematic diagram of the Y3-Y3' section line of the engaging structure M3, and Figure 10C Show along Figure 9 A cross-sectional view of the Z3-Z3' section line of the locking structure M3 is shown below. Following this, the following text will mainly describe the differences between the locking structure M3 and the aforementioned locking structure M2, and details that are the same as or similar to those of the locking structure M2 will not be repeated here.

[0128] Specifically, although the above embodiments all show the engagement member 500 formed in the recess U1 of the back plate 210, according to this embodiment, the engagement member 500 can actually be provided without the recess U1. Continuing from the above, as... Figure 8 As shown, the engaging member 500 of the engaging structure M3 can be directly disposed on the back side S2 of the back plate 210 and protrude from the back side S2. Conversely, the frame 300, facing away from the back plate 210, can protrude a convex portion T2, which is recessed into the supporting surface S3 of the frame 300 facing the back plate 210. Furthermore, the engaging structure M3 can have an engaging groove 600 in the same or similar form as the engaging groove 600 of the engaging structure M2, and this engaging groove 600 can be disposed in the convex portion T2.

[0129] Furthermore, the sidewall of the protruding portion T2 corresponding to the engaging groove 600 may have a thickened structure, and when assembled, it may extend toward the back surface S2 of the back plate 210. Therefore, referring to... Figures 9 to 10C With the snap-fit ​​structure M3 assembled, the snap-fit ​​member 500 protruding from the back side S2 can be surrounded and covered by the outward protrusion T2, reducing the length of the snap-fit ​​member 500 extending beyond the snap-fit ​​hole 610 of the snap-fit ​​groove 600. This makes the assembled frame 300 and back panel 210 appear more complete, and reduces or avoids unexpected bending of the protruding snap-fit ​​member 500 due to impact, or abrasion or scratches on the protruding snap-fit ​​member 500 that may further damage the rear cover. However, the above are merely examples, and other embodiments according to the present invention are not limited thereto. For example, according to some embodiments, with sufficient unit installation space, it is also possible to simply provide the snap-fit ​​member 500 protruding from the back side S2 without providing the outward protrusion T2 to provide the snap-fit ​​groove 600, thereby simplifying the manufacturing process of the snap-fit ​​structure.

[0130] Next, refer to Figures 11 to 13B The engaging structure M4 according to an embodiment of the present invention is shown in detail. Continuing from the above, Figure 11 This shows the engagement mechanism M4 in an unassembled state, and Figure 12 The assembly state of the locking mechanism M4 is shown. Additionally, Figure 13A Show along Figure 12 A cross-sectional schematic diagram of the X4-X4' section line of the engaging structure M4, and Figure 13B Show along Figure 12 A cross-sectional view of the Y4-Y4' section line of the locking structure M4. Following this, the following text will mainly describe the differences between the locking structure M3 and the aforementioned locking structure M2, and details that are the same as or similar to the locking structure M2 will not be repeated here.

[0131] Specifically, according to the engaging structure M4 of this embodiment, the inner groove U1 provided on the back surface S2 of the back plate 210 and the engaging member 500 provided in the inner groove U1 can be the same as or similar to the inner groove U1 and engaging member 500 of the engaging structure M2. Furthermore, according to this embodiment, the engaging groove 600 provided on the frame 300 of the engaging structure M4 is different in appearance and form from the engaging groove 600 of the engaging structure M2. Specifically, the engaging groove 600 of the engaging structure M4 penetrates the support portion 310 of the frame 300 and is formed on the support portion 310, and has an engaging hole 610, a connecting groove 620 that at least partially communicates with the engaging hole 610, a first slot 670, and a second slot 680. Referring to the above... Figure 11 The connecting groove 620 passes through the connecting engagement hole 610 and extends from opposite sides of the engagement hole 610 to have a first end 621 and a second end 622, respectively. For example, the connecting groove 620 may extend along a second direction D2 that is substantially parallel to the back surface S2 and perpendicular to the first direction D1, and pass through the connecting engagement hole 610 in the middle and extend to both ends to have a first end 621 and a second end 622, respectively.

[0132] Continuing from the above, according to the engaging structure M4 of this embodiment, the middle section of the first slot 670 can cross-connect with the first end 621, and the middle section of the second slot 680 can cross-connect with the second end 622. Thus, the connecting groove 620, the first slot 670, and the second slot 680 can surround and define the first flip spring F1 and the second flip spring F2. Continuing from the above, according to this embodiment, the first flip spring F1 and the second flip spring F2 can be flipped open to enlarge the connecting groove 620 and the engaging hole 610. Therefore, although the width W1 of the stop portion 510 of the engaging member 500 in the first direction D1 is greater than the width B1 of the engaging hole 610 in the first direction D1, the engaging hole 610 can be enlarged by flipping open the first flip spring F1 and the second flip spring F2. Thus, the engaging hole 610 can be directly aligned through the engaging member 500 to secure the engaging member 500 to the engaging hole 610.

[0133] As mentioned above, refer to Figures 12 to 13B After the first flip cover spring F1 and the second flip cover spring F2 are opened and pass through the locking member 500, the protruding stop part 510 of the locking member 500 can press on the first flip cover spring F1 and the second flip cover spring F2 after they are opened and return to their original position and be positioned, so that the back plate 210 and the frame 300 are mutually positioned and locked.

[0134] Next, refer to Figure 14 According to another embodiment of the present invention, the engaging structure M5 may have the same structure as the engaging structure M4 described above, but may further include a first auxiliary slot 670' and a second auxiliary slot 680'. Specifically, the engaging structure M5 may further include a first auxiliary slot 670' partially split on the side of the first flap spring F1 opposite to the connecting groove 620, and a second auxiliary slot 680' partially split on the side of the second flap spring F2 opposite to the connecting groove 620. This reduces, alleviates, or dissipates the deformation stress or pressure at the corresponding locations of the first auxiliary slot 670' and the second auxiliary slot 680' when the first flap spring F1 and the second flap spring F2 are opened. (Refer to...) Figure 14 According to some embodiments, the first auxiliary slot 670' and the second auxiliary slot 680' may be strip-shaped slots that are generally parallel to the connecting groove 620, or may be T-shaped slots that are at least partially generally parallel to the connecting groove 620. Therefore, the form or shape of the first auxiliary slot 670' and the second auxiliary slot 680' according to other embodiments of the present invention is not limited to this, in order to reduce, alleviate, or conduct and dissipate the stress or pressure of opening the first flip cover spring F1 and the second flip cover spring F2.

[0135] According to some embodiments, in order to guide the engagement of the engaging member 500 with the engaging hole 610, the engaging groove 600 may further have a sloping surface structure. For example, referring to... Figure 15A and Figure 15B The engaging groove 600 of the engaging structure M6, which is the same as or similar to the engaging structure M1 in the above embodiment, may have an engaging hole 610, a connecting groove 620, and an inlet 630. Continuing on this, the sidewalls V1, V2, V3, or combinations thereof defining the engaging hole 610, connecting groove 620, inlet 630, or combinations thereof in the frame 300 may have a ramp surface SL. These ramp surfaces SL are formed on the reverse side S4 of the frame 300 facing away from the back plate 210. Therefore, when the stop portion 510 of the engaging member 500 passes through the engaging groove 600 of the frame 300, it can move or be guided to the desired positioning position along the ramp surface SL.

[0136] Similarly, the engaging groove 600 in the engaging structure according to various embodiments of the present invention can be provided with a sloping surface SL on the side wall, and will not be described in detail here.

[0137] Furthermore, regardless of whether a ramp surface SL is provided, according to various embodiments of the present invention, the side wall V1 of the engaging hole 610 can assist in supporting the stop portion 510 and the connecting portion 520 of the engaging member 500.

[0138] As described above, by providing one or more engaging structures according to various embodiments of the present invention (e.g., engaging structures M1, M2, M3, M4, M5, M6 or variations thereof), and selectively using some or all of the engaging structures for assembly, different components, such as the frame 300 and the back plate 210, can be assembled without relying on connecting parts (e.g., screws) or connecting tools (e.g., screwdrivers, electric screwdrivers), or manual adjustment. Furthermore, if the alignment is correct, multiple or all engaging structures can be assembled simultaneously by simply pushing, thereby reducing the time required for engaging assembly. Therefore, components can be aligned to the intended assembly position with reduced or avoided use of costly and labor-intensive screw fastening, thereby reducing manufacturing assembly time and costs, simplifying the assembly process, and simultaneously improving the yield of the assembled product.

[0139] Furthermore, before assembly, components such as frame 300 may exhibit twisting or warping (e.g., injection molding surface curvature due to injection molding). Therefore, even with simple locking assembly using a small number of locking mechanisms FX, while frame 300 and back plate 210 may be securely assembled, unlocked portions, such as the sides of frame 300, may experience twisting or warping relative to back plate 210. This deformation of unlocked components can affect the final product's appearance and quality, even hindering subsequent manufacturing processes, and may further necessitate rework or even irreparable destruction. Continuing from the above, refer to... Figure 16A and Figure 16B According to some embodiments of the display device 20, by additionally providing a locking structure M (which can be any locking structure of the present invention) outside the locking mechanism FX, the portion that is deformed due to not being directly locked can be further corrected, for example, along the deformation correction direction CV. Therefore, the appearance, stability, and reliability of the assembled product can be improved. For example, the generation of defects such as deformation, twisting, gaps, or steps in the assembled product can be reduced or avoided, thereby reducing or avoiding the need for rework or even rejection of the assembled product, or reducing or avoiding the deterioration of the quality or appearance of the final product.

[0140] As described above, according to various embodiments of the present invention, the manufacturing process efficiency of assembly can be improved, the cost and manpower required for assembly can be reduced, and the appearance and quality of the assembled product can be further improved.

[0141] Furthermore, according to yet another embodiment of the present invention, referring to... Figure 17 Instead of directly securing the engaging hole 610 with the engaging component 500, assembly can be achieved by indirectly securing the engaging component 500 to the engaging hole 610 using a positioning fastener, such as a positioning fastener PF. For example, such as Figure 17 As shown, the positioning fastener PF can be configured to fasten the engaging member 500 by the lower part PF2 of the positioning fastener PF, and to position and engage the back plate 210 and the frame 300 by the upper part PF1 of the positioning fastener PF passing through the engaging hole 610 and protruding from the frame 300.

[0142] In addition to the mechanism that can fasten the card assembly 500, refer to Figure 18 According to some embodiments, the positioning component PF' may further include mechanisms to assist in positioning and confirmation. Specifically, the positioning fastener PF' may include: a main housing 900, a guiding member 700 located in the main housing 900, and an elastic member 800 located in the main housing 900. In detail, according to this embodiment, the positioning component PF' can clamp and hold the engaging member 500 by being configured to engage the engaging member 500 through the bottom 920 of the main housing 900. In addition, the main housing 900 also further engages the guiding member 700. The guiding member 700 extends toward the top 910 of the main housing 900 away from the space where the engaging member 500 is expected to engage, and has a body 720 and a protrusion 710 protruding away from the bottom 920 of the main housing 900 relative to the body 720. Continuing above, the main housing 900 may have at least one side opening 905, 915 in the middle section between the bottom 920 and the top 910, which can expose at least a portion of the body 720. Additionally, the top 910 of the main housing 900 may have a top wall TP, and the top wall TP may have a top opening OP corresponding to the protrusion 710. For example, the top 910 of the main housing 900 may have an annular top wall TP, and the annular top wall TP defines a circular top opening OP. The top opening OP may correspond to the protrusion 710 of the guiding member 700, and the protrusion 710 may extend out of or be housed in the main housing 900 through the top opening OP.

[0143] As described above, according to this embodiment, the main body shell 900 may be further provided with an elastic member 800, and the elastic member 800 can respectively abut against the top wall TP and the body 720 to position the guiding member 700. For example, as Figure 18 right side and Figure 19As shown, in the positioning fastener PF' assembled with the main body shell 900, the elastic component 800, and the guiding component 700, the elastic component 800 can be a ring-shaped spring wound around the protrusion 710, and abuts against the main body 720 and the annular top wall TP at both ends in the elastic direction. In this configuration, the area of ​​at least a portion of the main body 720 parallel to the top opening OP can be larger than the area of ​​the protrusion 710 parallel to the top opening OP, and therefore the elastic component 800 wound around the protrusion 710 can abut against at least a portion of the main body 720 and the top wall TP, thereby positioning the guiding component 700 at a specific position or within a preset range through elasticity.

[0144] The aforementioned guiding component 700, elastic component 800, or combinations thereof, can be assembled with the main housing 900 by machining and stamping, or directly by using an overmolding injection mold. However, positioning fasteners according to other embodiments of the present invention may further include other components or other variations, and can be assembled using any applicable manufacturing process. Therefore, the present invention is not limited thereto, and the above are merely examples.

[0145] According to some embodiments, such as Figure 19 As shown, at least a portion of the body 720 of the guide member 700 may have a guide ramp 725, and the guide ramp 725 may be exposed through at least one side opening 905, 915. For example, the side openings 905 and 915 may face the sidewall of the engagement groove, and thus expose at least a portion of the body 720 of the guide member 700, such as the guide ramp 725, corresponding to the sidewall of the engagement groove. As described above, in a plane (e.g., plane AR) perpendicular to the height direction D3 of the guide member 700 along the bottom 920 of the main body housing 900 toward the top 910 of the main body housing 900, the cross-sectional area of ​​the guide member 700 gradually expands along the guide ramp 725 from the bottom 920 of the main body housing 900 toward the top 910 of the main body housing 900. Therefore, when the positioning fastener PF' of the engaging member 500 passes through the engaging groove 600 described above, the guide ramp 725 can slide along the engaging groove 600. Possible deformations and misalignments can be corrected through the interactive movement of the guide ramp 725 contacting and pressing against the sidewalls of the engaging groove 600 on opposite sides. This positions the positioning fastener PF' on the engaging hole 610 with the desired positioning accuracy. In this case, the portion of the guide member 700 including the guide ramp 725 can function in the same or similar way as the stop portion 510 of the engaging member 500 in the embodiments described above, and the engagement state with various types of engagement structures can be the same or similar to the engagement state of the stop portion 510 with the frame 300 in the embodiments described above. These will not be shown or described in detail here.

[0146] In some embodiments, this positioning fastener PF' may also interact with the ramp surface described above on the sidewall of the engagement groove 600. For example, when the engagement groove 600 includes an inlet 630, a connecting groove 620, and an engagement hole 610, similar to engagement structure M1, the sidewall defining the inlet 630, connecting groove 620, and engagement hole 610, or a combination thereof, may have a ramp surface formed on the reverse side S4 of the frame 300 facing away from the back plate 210. Thus, the guide ramp 725 can slide on the ramp surface to guide the positioning member 700 from its initial state to a state where the frame 300 and the back plate 210 are positioned and engaged. Furthermore, similar guidance can be applied to other types of engagement structures, which will not be described in detail here.

[0147] Next, continue to refer to Figure 19 According to some embodiments of the present invention, in order to assist in positioning and securing the engaging member 500 and the guiding member 700, the main housing 900 may further have a first positioning protrusion 930 protruding inwards from the main housing 900. Continuing above, according to this embodiment, the first positioning protrusion 930 can restrict the movement of the guiding member 700 toward the bottom 920 of the main housing 900, and the first positioning protrusion 930 can restrict the movement of the engaging member 500, which is secured by the main housing 900, toward the top 910 of the main housing 900. That is, through the separation by the first positioning protrusion 930, the guiding member 700 can be prevented from moving toward the bottom 920 of the main housing 900, and the engaging member 500 can be prevented from moving toward the top 910 of the main housing 900. Thus, the engaging member 500 and the guiding member 700 can be secured by the main housing 900 without direct contact between the guiding member 700 and the engaging member 500.

[0148] In addition, such as Figure 19As shown, the main housing 900 may also have a second positioning protrusion 940 protruding inward from the top wall TP relative to the first positioning protrusion 930. As described above, the second positioning protrusion 940 helps to limit the movement of the engaging member 500, which is secured by the main housing 900, toward the bottom 920 of the main housing 900. That is, by separating the engaging member 500 with the second positioning protrusion 940, the stop portion 510 can be prevented from moving toward the bottom 920 of the main housing 900. Furthermore, the second positioning protrusion 940 may have a guide ramp SL' such that the length of the second positioning protrusion 940 protruding inward from the bottom 920 of the main housing 900 toward the top 910 of the main housing 900 gradually increases, or the guide ramp SL' faces toward the bottom 920 of the main housing 900. Therefore, the guide ramp SL' can be configured such that a portion of the guide engagement member 500 (e.g., the stop portion 510) slides between the first positioning protrusion 930 and the second positioning protrusion 940, and is restrained and clamped by the first positioning protrusion 930 and the second positioning protrusion 940. Thus, unintended misalignment or detachment of the engagement member 500, which is fastened by the main body housing 900, can be reduced or avoided, and the strength of the fastening engagement member 500 is increased, thereby improving the stability and accuracy of the engagement positioning of the engagement member 500 against the engagement groove 600 via the positioning fastener PF'.

[0149] The following description uses a similar engaging structure M1 as an example to illustrate the engaging and positioning process using the positioning fastener PF'. However, other embodiments of the present invention are not limited thereto, and those skilled in the art should be able to similarly apply the positioning fastener PF' to other types of engaging structures with reference to the description, which will not be elaborated upon here.

[0150] As mentioned above, referring to Figure 20A and Figure 20B The diagram shows the positioning fastener PF' in a first state A1 before reaching the final expected assembly completion position. That is, in the first state A1, the upper part PF1 of the positioning fastener PF' may not protrude through the engagement hole 610 from the frame 300, thereby failing to engage the positioning back plate 210 and the frame 300. In this case, the elastic member 800 can push the guiding member 700 away from the top wall TP, such that the protrusion 710 does not protrude from the main body shell 900 through the top opening OP, or the length of the protrusion 710 protruding from the main body shell 900 through the top opening OP is a first length L1.

[0151] As described above, according to the engaging structure shown in this embodiment, the positioning fastener PF' can be secured to the engaging member 500, and the upper part PF1 of the positioning fastener PF' can pass through the inlet 630 and sequentially move through the connecting groove 620 to the engaging hole 610. During this process, guided by the engaging structure, the positioning fastener PF' can be moved relative to the engaging hole 610 and engaged according to the expected engaging position. Among them, the side walls V3, V2 and V1 of the engaging groove can be pushed upward in the first state A1 through at least a part of the body 720 of the guide member 700 exposed by at least one side opening 905, 915 (e.g., but not limited to the guide slope 725), so that the top edge EP of the guide slope 725 gradually moves upward relative to the main body shell 900.

[0152] Next, refer to Figure 21A and Figure 21B When the main body shell 900 is fastened to the engaging member 500 as described above, and the upper part PF1 of the positioning fastener PF' protrudes through the engaging hole 610 and protrudes from the frame 300, thereby engaging the positioning back plate 210 and the frame 300 in the second state A2, the top edge EP of the guide slope 725 can move upward relative to the main body shell 900 and move away from the back plate 210 in the engaging hole 610. In addition, since the frame 300 can push the guiding member 700 closer to the side wall TP of the main body shell 900 through at least one side opening 905, 915 around the side wall V1 defining the engaging hole 610, the protrusion 710 can further protrude from the main body shell 900 through the top opening OP.

[0153] According to some embodiments, in the second state A2, the protrusion 710 can protrude from the main body shell 900 through the top opening OP by a length of the second length L2, and the second length L2 of the second state A2 is greater than the first length L1 of the first state A1. Specifically, when the frame 300 and back panel 210 are assembled by assembling the corresponding engaging member 500 and engaging hole 610 through the positioning fastener PF', at least a portion of the body 720 of the guide member 700 exposed through at least one side opening 905, 915 is pushed upward by the side wall of the engaging hole 610, and the entire guide member 700 moves upward against the downward elastic force of the elastic member 800. Therefore, the protrusion 710 of the guide member 700 can further protrude from the main body shell 900 through the top opening OP. Thus, as... Figure 21B As shown, the correctness of the assembly and engagement can be determined by observing whether the protrusion 710 protrudes further from the main body shell 900 through the top opening OP.

[0154] As described above, the visible change in position of the positioning fastener PF' from the first state A1 to the second state A2 where the assembly is complete (for example, depending on the degree to which the protrusion 710 protrudes from the main body shell 900) can help determine whether the assembly of the frame 300 and the back plate 210 is complete, or whether the assembly positioning has been performed correctly without misalignment. Therefore, the assembly process can be accelerated, and the reliability of the assembled product can be improved. This reduces or avoids the inspection work required due to uncertainty about whether the assembly is complete, or reduces or avoids rework procedures or even rejection due to assembly defects. Furthermore, in cases where rework is necessary, according to this embodiment, the detachably assembleable positioning fastener PF' reduces the difficulty of rework, increasing the ease of rework and yield.

[0155] According to other embodiments of the present invention, the positioning fastener can be used to lock and fix the fastener in place with the engaging structure of the various embodiments of the present invention, and the specific accompanying drawings and descriptions above are merely examples. Therefore, the engaging structure that the positioning fastener can be used with is not limited to the specific examples described herein, and those skilled in the art should understand other applications of the positioning fastener from the above description, which will not be elaborated upon here.

[0156] In summary, in the display device according to various embodiments of the present invention, the locking mechanism is disposed on the opposing surfaces of the frame and the backplate (e.g., the supporting surface of the frame and the back side of the backplate), without further occupying the space for the components disposed within the backlight module or outside the frame. This reduces or avoids impacting the placement of the components in the backlight module and the efficiency of light emission, and also reduces or avoids defects in the locking mechanism that may be visible. Furthermore, by using the locking mechanism, locking can replace screw fastening or magnets, reducing assembly time and costs, and increasing assembly yield, thereby reducing or avoiding the need for rework or discarding. Further, if rework is indeed necessary, the cost of rework can be reduced, and damage to the components that may be caused during disassembly for rework can be avoided, thus improving rework efficiency and yield. Additionally, in the display device according to various embodiments of the present invention, even without screw fastening or with only limited screw fastening, the use of one or more locking mechanisms and the selective engagement of corresponding parts or all of them allows for more flexible and adaptable application to the assembly and manufacturing processes of components with various industrial designs.

[0157] The above description is merely a selection of preferred embodiments of the present invention. It should be noted that various changes and modifications can be made to the present invention without departing from its spirit and principles. Those skilled in the art should understand that the present invention is defined by the appended claims, and that various possible substitutions, combinations, modifications, and uses, etc., do not exceed the scope defined by the appended claims, provided they conform to the intent of the present invention.
