[0055] The following describes the implementation of the connection assembly disclosed in the present invention through specific embodiments and accompanying drawings. Those skilled in the art will understand the advantages and effects of the present invention from the content disclosed in this specification. However, the content disclosed below is not intended to limit the scope of protection of the present invention. Without departing from the spirit of the present invention, those skilled in the art may implement the present invention in other different embodiments based on different viewpoints and applications. In the drawings, the thickness of layers, films, panels, regions, etc. is exaggerated for clarity. Throughout this specification, the same reference numerals represent 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 can be directly on or connected to the other element, or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, no intervening elements are present. As used herein, "connected" can refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" can mean the presence of other elements between two elements.

[0056] 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 portions, these elements, components, regions, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Thus, a "first element," "component," "region," "layer," or "portion" discussed below may be referred to as a second element, component, region, layer, or portion without departing from the teachings herein.

[0057] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" can include both "lower" and "upper" orientations, depending on the particular orientation of the figure. Similarly, if the device in one figure is turned over, the element described as being "below" or "beneath" the other elements will be oriented as being "above" the other elements. Thus, the exemplary term "below" or "below" can include both "upper" and "lower" orientations.

[0058] As used herein, "about," "approximately," or "substantially" includes the stated value and an average value that is within an acceptable deviation range of the particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the particular amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, or ±5%. Furthermore, as used herein, "about," "approximately," or "substantially" can be selected based on the optical property, etching property, or other property, and may not apply to all properties with a single standard deviation.

[0059] like Figure 2 As shown in the schematic diagram of the embodiment, the back panel 800 of the present invention includes a back panel body 100, a back panel side wall 200, a tongue 300 and a stiffening structure 400. A portion of one side edge of the back panel body 100 retreats inward to form a recess 110, and the recess 110 includes a first side edge 111 and a recess bottom edge 113. Furthermore, the recess 110 may include a second side edge 112 opposite to the first side edge 111, and the recess bottom edge 113 is located between the first side edge 111 and the second side edge 112. The back panel side wall 200 extends from the edge of the back panel body 100 in a direction perpendicular to the back panel body 100 and away from the back panel body 100. The tongue 300 is formed by the back panel side wall 203 located at the recess bottom edge 113 (see Figure 3A 、 3B ) and extends in a direction parallel to the back panel body 100 and away from the bottom edge 113 of the recess. There is a structural gap between the tongue 300 and the back panel side wall located on the adjacent side of the recess. The stiffening structure connects the tongue and the top of the back panel side wall located on the side of the recess. For example, there is a structural gap 500 between the tongue 300 and the back panel side wall 202 located on the adjacent second side 112, and the stiffening structure 400 connects the tongue 300 and the top of the back panel side wall 202. Accordingly, the structural gap 500 can be shielded by the stiffening structure 400, which can reduce the occurrence of broken pieces when assembling a display device using this back panel 800. Viewed from different angles, the structural gap 500 is in the XY plane (see Figure 2 ) can be covered by the vertical projection of the stiffening structure 400 on the XY plane.

[0060] Furthermore, if Figure 2As shown, in one embodiment, the backplate body 100 is arranged in a direction parallel to the XY plane, the backplate sidewall 200 is arranged in a direction parallel to the Z axis, and the tongue 300 is arranged in a direction parallel to the XY plane. The X axis, Y axis, and Z axis are orthogonal. Among them, the backplate 800 is preferably formed by stamping. In other words, the backplate sidewall 200 and the tongue 300 are preferably formed by stamping at the edge of the backplate body 100, and a structural gap 500 is naturally formed between the backplate sidewall 200 and the tongue 300.

[0061] In one embodiment, the reinforcing structure 400 of the back plate 800 is connected to the sheet material on the side of the tongue 300 extending in the same direction as the bottom edge 113 of the recess, and is bent relative to the tongue 300 toward the bottom edge 113 of the recess. Further, the reinforcing structure 400 is connected to the sheet material on the side of the tongue 300 in a U-shaped bend. More specifically, as Figure 3A As shown, the side of the tongue 300 away from the back plate body 100 has a sheet 400'. The width of the sheet 400' is slightly smaller than the tongue, and one corner is connected to the tongue 300 and extends outward. Figure 3B As shown, the sheet 400' is bent outward (ie, toward one side 301 of the tongue 300) in a U-shape so as to at least partially overlap the side 301. In this embodiment, the bent sheet 400' overlaps the outside of the tongue 300 and extends toward the second side 112. Then, as shown in FIG. Figure 3C As shown, the tongue 300 is bent along the fold line 309, so that the side of the sheet away from the tongue 300 is connected to the top of the back panel side wall 202 located on the second side 112, forming a stiffening structure 400. The stiffening structure 400 can be connected to the top of the back panel side wall located on the side of the recess by welding or gluing, and preferably crosses the top of the back panel side wall located on the side of the recess.

[0062] Figures 4A to 4C For the above Figures 3A to 3C Schematic diagrams of different viewing angles of the stiffening structure 400 formed by U-shaped bending. Figure 4A As shown, the tongue 300 has a sheet 400' on the side away from the back plate body 100. Figure 4B As shown, the sheet is U-bent so as to overlap at least partially with one side 301 of the tongue 300. Figure 4C As shown, the tongue 300 is bent along the fold line 309 so that the end of the sheet away from the tongue 300 is connected to the top of the back panel side wall 202 located at the second side edge 112 to form a stiffening structure 400. Figure 4C As shown, there is a structural gap 500 between the tongue piece 300 and the back plate sidewall 202 located at the adjacent second side 112. A surface 301 of the tongue piece 300 parallel to the back plate body 100 is provided for a circuit board (not shown).

[0063] In various embodiments, the reinforcing structure 400 of the back plate 800' is formed by a U-shaped slice inside the tongue 300 and bent in a U-shaped manner. Further, the reinforcing structure 400 is a slice surrounded by a U-shaped slit on the tongue 300 and bent relative to the tongue 300 toward the second side 112. More specifically, Figure 5A As shown, the tongue 300 has a slice 400" surrounded by a U-shaped slit. The slice 400" is turned outward along the fold line 308 and bent toward the second side 112, as shown in FIG. Figure 5B The tongue 300 is extended as shown. Then, as shown Figure 5C As shown, the tongue piece 300 is bent along the fold line 309 so that the end of the U-shaped slice 400 ″ away from the tongue piece 300 is connected to the top of the back panel side wall 202 located at the second side edge 112 to form a stiffening structure 400 . Figures 6A to 6C Schematic diagrams of different viewing angles of the stiffening structure 400 formed by the U-shaped bending method. Figure 6A As shown, the tongue 300 has a U-shaped slice 400' inside. After the U-shaped slice 400' is bent along the fold line 308, as shown in FIG. Figure 6B The tongue 300 is extended as shown. Then, as shown Figure 6C As shown, the tongue 300 is bent along the fold line 309, so that the end of the U-shaped slice 400" away from the tongue 300 is connected to the top of the back panel side wall 202 located at the second side edge 112 to form a stiffening structure 400. Figure 6C As shown, there is a structural gap 500 between the tongue 300 and the back panel side wall 202 located at the adjacent second side 112. A side 301 of the tongue 300 parallel to the back panel body 100 can be provided for a circuit board (not shown). In the aforementioned embodiment, the stiffening structure 400 is essentially the same sheet material as the tongue 300. However, in different embodiments, the stiffening structure 400 may be another sheet material different from the tongue 300, that is, an external method is adopted to connect the two ends of a sheet material to the tongue and the top of the adjacent back panel side wall 202 to form the stiffening structure 400. In addition, the sheet material can be made of a material different from that of the tongue.

[0064] like Figure 7 In the illustrated embodiment, a display device 900 of the present invention includes a backplate 800, a liquid crystal module 600, and a circuit board 700. The liquid crystal module 600 is disposed on one side of the backplate 800. The circuit board 700 is electrically connected to the liquid crystal module 600 and is disposed on the other side 301 of the tongue 300, opposite the liquid crystal module 600. The circuit board 700 and the vertical projections of the liquid crystal module 600 on the tongue 300 at least partially overlap. Opposite sides of the tongue 300 are secured to the liquid crystal module 600 and the circuit board 700 using double-sided tape 901 and 902, respectively.

[0065] The present invention has been described with reference to the above embodiments. However, the above embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and equivalents falling within the spirit and scope of the claims are intended to be within the scope of the present invention.
