Description

Technical Field

[0001] This invention relates to an electronic device, and more particularly to a display device. Background Technology

[0002] Taking a display device used in a laptop as an example, it consists of at least a front frame, a display module, and a back cover. Generally, the display module is mostly fixed to the front frame with adhesive or tape, and may also be secured with multiple screws. On the other hand, the back cover is mostly secured to the front frame with multiple screws to clamp and fix the display module between the front frame and the back cover. Therefore, during the disassembly and assembly of the display device, operators need to spend a considerable amount of time loosening or tightening the screws. In addition, during the removal of the display module, operators need to first use a heat gun to reduce the adhesion of the adhesive or tape before further removing the display module, which is not only time-consuming and labor-intensive, but may also damage the display module. Summary of the Invention

[0003] This invention relates to a display device that not only facilitates quick assembly and disassembly by operators, but also reduces the risk of damage to components during the assembly and disassembly process.

[0004] According to one embodiment of the present invention, the display device includes a front frame, a display panel, positioning plates, and a back cover. Each positioning plate is fixed to the display panel. Each positioning plate is snapped and locked to the front frame, and the display panel is fixed to the front frame via the positioning plates. The back cover is mounted on the front frame and covers the display panel and the positioning plates. The back cover is adapted to slide along a first direction between a first mounting position and a second mounting position relative to the first mounting position. As the back cover slides along the first direction from the first mounting position to the second mounting position, the back cover snaps into the front frame and is then locked to the front frame.

[0005] Based on the above, the display device of the present invention integrates the snap-fit ​​mechanism into the disassembly and assembly design of the display panel and the back cover, thereby reducing the amount of screws used. This not only facilitates quick disassembly and assembly by operators, but also reduces the risk of damage to the display panel during disassembly and assembly, while reducing resource consumption and waste generation.

[0015] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0016] Figure 1A and Figure 1B This is a schematic diagram of a display device according to an embodiment of the present invention from two different perspectives. Figure 1C yes Figure 1A An enlarged schematic diagram of region 1C. Figure 1D yes Figure 1B An enlarged schematic diagram of area 1D. To clearly show the mounting design between the back cover 140 and the front frame 110, and the mounting design between each positioning plate 130 and the front frame 110, at least a portion of the back cover 140 is in Figures 1A to 1D The text is shown in dashed lines. Please refer to it. Figures 1A to 1C In this embodiment, the display device 100 may be part of a laptop computer, but is not limited thereto. In detail, the display device 100 includes a front frame 110, a display module, and a back cover 140, wherein the back cover 140 is mounted on the front frame 110, and the display module is positioned between the front frame 110 and the back cover 140.

[0017] The display module may include a display panel 120 and two positioning plates 130, wherein the display surface of the display panel 120 faces the display opening of the front frame 110, and each positioning plate 130 is fixed to the back of the display panel 120. For example, the two positioning plates 130 may be symmetrically arranged on the back of the display panel 120, and may be fixed to the back of the display panel 120 by adhesive or tape, but this is not a limitation.

[0018] like Figure 1C As shown, each positioning plate 130 can engage with the front frame 110 to secure the display panel 120 to the front frame 110. Furthermore, each positioning plate 130 can be further locked and secured to the front frame 110 to more firmly install the display panel 120 onto the front frame 110. Since the display device 100 integrates the engagement mechanism into the disassembly and assembly design of the display panel 120, it helps reduce the amount of screws used and eliminates the need for adhesively fixing the display panel 120 to the front frame 110. This not only facilitates quick disassembly and assembly by operators but also reduces the risk of damage to the display panel 120 during disassembly and assembly, while simultaneously reducing resource consumption and waste generation.

[0019] like Figures 1A to 1D As shown, the back cover 140 is mounted on the front frame 110 and covers the back of the display panel 120 and each positioning plate 130, with each positioning plate 130 located between the display panel 120 and the back cover 140. Figure 1C As shown, the back cover 140 can employ a sliding engagement mechanism. By sliding the back cover 140 relative to the front frame 110 along the first direction D1, the back cover 140 can engage with the front frame 110 or disengage from the engagement. When the back cover 140 is engaged with the front frame 110, the back cover 140 cannot be detached from the front frame 110 along the second direction D2 perpendicular to the first direction D1. Conversely, after disengaging from the front frame 110, the back cover 140 can be detached from the front frame 110 along the second direction D2 perpendicular to the first direction D1.

[0020] like Figure 1C and Figure 1D As shown, after the back cover 140 is engaged with the front frame 110, the back cover 140 can be further locked and fixed to the front frame 110 to more securely install the back cover 140 on the front frame 110, preventing the engagement between the back cover 140 and the front frame 110 from being accidentally released by external force. Since the display device 100 integrates the engagement mechanism into the disassembly and assembly design of the back cover 140, it helps to reduce the amount of screws used, which not only facilitates quick disassembly and assembly by operators, but also reduces resource consumption and waste generation.
