Description

Technical Field

[0001] This invention relates to a rear cover for a display device and the display device itself. Background Technology

[0002] Various flat panel displays, such as liquid crystal displays (LCDs), are widely used in electronic products such as computers, televisions, and mobile phones. The display module, which includes optical films, liquid crystal modules, and backlight modules, is one of the important components of an LCD, and its assembly directly affects the cost and durability of the LCD.

[0003] like Figure 1A and 1B The prior art shown, wherein Figure 1B yes Figure 1A The enlarged view of the central area 410 shows that the common assembly method for display modules involves setting positioning posts 30 on the back plate 10 of the rear shell 80 near the side wall 20, and as shown in the image. Figure 2 and 3 The engagement portion 51, which has a middle frame 50, engages with the positioning post 30 to fix the middle frame 50. This allows the display module to be positioned between the middle frame 50 and the rear housing 80. However, since the engagement portion 51 essentially clamps the positioning post 30, the positioning post 30 is more susceptible to deformation and breakage due to pulling on the engagement portion 51 during assembly or disassembly, increasing parts and manufacturing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a back cover for a display device that can reduce manufacturing costs and improve durability.

[0005] Another object of the present invention is to provide a display device that can reduce manufacturing costs and improve durability.

[0006] The rear housing of the display device of the present invention is used in conjunction with a display module and its middle frame. The rear housing includes a back plate, a first sidewall, and a support member. The first sidewall extends upward from a first side edge of the back plate. The support member is disposed on the top surface of the back plate adjacent to the first sidewall. The top surface of the support member can abut against the bottom surface of the display module, and the middle frame is at least partially confined between the support member and the first sidewall.

[0007] The display device of the present invention includes a display module having a middle frame and a display device rear shell. Attached Figure Description

[0045] The following specific embodiments, in conjunction with drawings, illustrate implementations of the connection components disclosed in this invention. Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. However, the following disclosure is not intended to limit the scope of protection of this invention. Those skilled in the art can implement this invention in other different embodiments based on different viewpoints and applications without departing from the spirit of the invention. In the drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected" to another element, it may be directly on or connected to the other element, or an intermediate element may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected" to another element, no intermediate element is present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" may mean that other elements exist between two elements.

[0046] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, the “first element,” “component,” “region,” “layer,” or “part” discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of this document.

[0047] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to other elements will be oriented to be “up” to other elements. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” other elements will be oriented to be “above” other elements. Thus, the exemplary term “below” or “under” can include both “up” and “down” orientations.

[0048] As used herein, “about,” “approximately,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” or “substantially” herein may be chosen based on the optical, etched, or other properties to select a more acceptable range of deviations or standard deviations, and may not require a single standard deviation to apply to all properties.

[0049] The rear housing of the display device of the present invention is used in conjunction with a display module and its mid-frame. In one embodiment, the display module includes a display panel and a mid-frame, with the mid-frame surrounding the display panel. "Surrounding" also includes the case where the mid-frame is positioned below the display panel and distributed along the side of the display panel. For ease of explanation, in the following embodiments, the rear housing of the display device is considered to be placed on a plane, and the display module is disposed on the rear housing of the display device; that is, the rear housing and the display module are located below and above, respectively. "Upward" means closer to the display module and away from the plane, and "downward" means closer to the plane and away from the display module.

[0050] like Figure 4A and Figure 4B The embodiment shown, wherein Figure 4B yes Figure 4AAn enlarged view of region 420 shows that the rear housing 800 of the display device of the present invention includes a back plate 100, side walls 200, and a support member 300. The side walls 200 extend upward from the side edges of the back plate 100. In one embodiment, the back plate 100 is rectangular, and the side walls 200 include a first side wall 210, a second side wall 220, a third side wall 230, and a fourth side wall 240 extending upward from the four side edges of the back plate 100, respectively. The first side wall 210, the second side wall 220, the third side wall 230, and the fourth side wall 240 may be connected for reasons such as increasing strength or not connected for reasons such as facilitating assembly. Furthermore, they may be formed by bending upward from the side edges of the back plate 100.

[0051] Support members 300 are disposed on the top surface of the back panel 100 near the sidewall 200. The support members 300 can be manufactured using methods such as embossing, bending, or injection molding. In different embodiments, the distribution of the support members 300 can be adjusted according to design or usage requirements. For example, in one embodiment, if the display module is smaller than 24.5 inches, at least six support members 300 may be evenly distributed near the first sidewall 210, and at least four support members 300 may be evenly distributed near the second sidewall 220 and the third sidewall 230, respectively. In another embodiment, if the display module is 27 inches in size, at least seven support members 300 may be evenly distributed near the first sidewall 210, and at least four support members 300 may be evenly distributed near the second sidewall 220 and the third sidewall 230, respectively. In another embodiment, the size of the display module is between 31.5 inches and 32 inches, and the support members 300 adjacent to the first sidewall 210 can be provided in an average of 8 or more, and the support members 300 adjacent to the second sidewall 220 and the third sidewall 230 can be provided in an average of 5 or more respectively.

[0052] like Figure 5A and 5B In one embodiment shown, the middle frame 500 includes a downwardly extending insert 510. The insert 510 corresponds to the support member 300 and is insertable and confined between the support member 300 and the first sidewall 210. More specifically, as... Figure 6In the illustrated embodiment, when the plug-in 510 is inserted and engaged between the support member 300 and the first sidewall 210, the middle frame 500 presses down on the display module 600, causing the top surface 301 of the support member 300 to abut against the bottom surface 601 of the display module 600. In other words, when the top surface 301 of the support member 300 abuts against the bottom surface 601 of the display module 600, the middle frame 500 is at least partially confined between the support member 300 and the first sidewall 210, thereby fixing the middle frame 500 relative to the rear shell 800 of the display device, thereby confining the display module 600 between the middle frame 500 and the rear shell 800 of the display device. At this time, the top surface 301 of the support member 300 is flush with the bottom surface 601 of the display module 600. The display device 900 of the present invention includes a display module 600 containing the middle frame 500 and a rear shell 800 of the display device.

[0053] Since the mid-frame 500 is fixed by inserting a plug 510 between the support member 300 and the first sidewall 210, meaning that the plug 510 does not clamp the support member 300 on one side only, the support member 300 will not deform or break during assembly or disassembly due to the removal or insertion of the plug 510. This reduces manufacturing costs and improves durability. From different angles, the support member 300 now serves both to fix the mid-frame 500 and to support the display module 600, meaning that the display module 600 can be supported without additional support components, further saving costs.

[0054] like Figure 5AAs shown, in one embodiment, the thickness W2 of the insert 510 is approximately equal to the distance between the support member 300 and the first sidewall 210, i.e., the gap W1, thereby improving the engagement effect. Furthermore, when the insert 510 engages between the support member 300 and the first sidewall 210, due to the elasticity of the material, the insert 510 can be slightly compressed, or the support member 300 and the first sidewall 210 can be slightly opened, allowing the insert 510, support member 300, and first sidewall 210 to engage tightly. In one embodiment, the thickness of the insert 510 is 0.6mm to 1.2mm, and when the insert 510 is inserted and confined between the support member 300 and the first sidewall 210, the distance between the insert 510 and the first sidewall 210 is 0.1mm to 0.3mm, and the distance between the insert 510 and the support member 300 is 0.1mm to 0.2mm. Furthermore, the thickness of the insert 510 can be less than the thickness of the middle frame 500 to maintain the overall strength of the middle frame 500 while facilitating the insertion of the insert 510 between the support member 300 and the first sidewall 210. In one embodiment, the insertion depth of the insert 510 between the support member 300 and the first sidewall 210 is 1.4 mm or more, which can achieve a better engagement effect. Viewed from different angles, in the above embodiment, the insert 510, support member 300, and first sidewall 210 can be tightly fitted. However, in another variation embodiment, the insert 510 can contact the support member 300, and the surface of the insert 510 in contact with the support member 300 can be specially treated, such as increasing roughness, to achieve the purpose of limiting the position.

[0055] like Figure 6 As shown, in one embodiment, the support member 300 has a guide slope 302 on the side near the first sidewall 210, facilitating the insertion of the plug 510 between the support member 300 and the first sidewall 210. The shell back plate 100 has a shell back plate slope 101 near the first sidewall 210 to reduce the sharp edges of the shell back plate 100, and the support member 300 can be correspondingly disposed on the shell back plate slope 101.

[0056] In such Figure 5B In the illustrated embodiment, the support member 300, projected vertically onto the shell back plate 100, is U-shaped with its opening facing the first sidewall 210. However, in different embodiments, the support member 300 may have different designs depending on manufacturing or design considerations. For example, in... Figure 7A In the embodiment shown, the vertical projection of the support member 300A onto the shell back plate 100 is a U-shape with an opening facing away from the first sidewall 210. Figure 7B In the embodiment shown, the vertical projection of the support member 300B onto the shell back plate 100 is L-shaped, with its long side close to the first sidewall 210. Figure 7A and 7BIn the illustrated embodiment, the supports 300A and 300B have longer side edges near the first sidewall 210. Therefore, when the plug 510 is inserted between the supports 300A and 300B and the first sidewall 210, the contact area between the supports and the plug can be further increased, thus enhancing the limiting effect. Figure 7C In the illustrated embodiment, the vertical projection of the support member 300C onto the shell back plate 100 is an H-shape perpendicular to the first sidewall 210. When the insert 510 is inserted between the support member 300C and the first sidewall 210, the insert 510 actually contacts both ends of the H-shaped structure of the support member 300C. This configuration can help resolve interference problems, for example, when there is interference between the support member and other assemblies. Figure 7D In the illustrated embodiment, the vertical projection of the support member 300D onto the shell back plate 100 is circular. When the insert 510 is inserted between the support member 300D and the first sidewall 210, the insert 510 theoretically contacts a line extending axially along the outer surface of the circular structure of the support member 300D. Viewed from different angles, this is the form with the smallest contact area, which can increase the ease of assembly.

[0057] The present invention has been described by the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, modifications and equivalents encompassing the spirit and scope of the claims are all included within the scope of the present invention.
