Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a display module and a vehicle-mounted display screen. Background Art

[0002] Currently displaying modules, such as Fig. 9 As shown, a back plate made of aluminum alloy is usually provided, on which a light-emitting component is installed, and a convex portion is provided at the upper edge of the back plate. The material of the convex portion is the same as that of the back plate, and the convex portion is designed to be of the same height, extending upward, and in contact with the outer frame, so as to support the outer frame. The outer frame is stuck on the convex portion, and the back plate, the convex portion, and the outer frame together form an installation space for installing the light-emitting component and the optical component. An expansion gap is reserved between the optical component and the convex portion, but the back plate and the convex portion are made of aluminum alloy. Due to the influence of the thickness of the aluminum alloy plate and the processing technology (the thickness of the aluminum alloy plate is usually more than 1.5 mm), the thickness of the convex portion is usually more than 1.5 mm, and a thinner convex portion cannot be processed, which results in a larger size from the visible area to the outside of the frame, and the module cannot achieve a narrow frame.

[0035] The utility model provides a display module. The utility model can achieve a narrow frame under the premise of ensuring that the expansion gap remains unchanged.

[0036] refer to Figure 1-Figure 7 The display module provided by the utility model includes: a back plate 1, the back plate 1 has an upper surface and a lower surface in the height direction, the upper surface is provided with a light-emitting component 2, and the two opposite sides in the length direction of the back plate 1 are provided with convex parts 3, the convex parts 3 protrude from the upper surface, and the top surface of the convex part 3 is provided with a supporting part 6, the material of the supporting part 6 is plastic, and in the height direction, the width value of the cross-sectional shape of the supporting part 6 is smaller than the width value of the cross-sectional shape of the convex part 3; an outer frame 4, the outer frame 4 is connected to the back plate 1, the outer frame 4 and the back plate 1 enclose an inner cavity 9 for accommodating the light-emitting component 2, the convex part 3 is arranged in the inner cavity 9, and is used to support the outer frame 4; and an optical component 5 is arranged in the inner cavity 9, the optical component 5 is located above the light-emitting component 2, the edge of the optical component 5 is arranged at the top surface of the convex part 3, a first gap 10 is provided between the side edge of the optical component 5 and the supporting part 6, and a second expansion gap is provided between the side edge of the optical component 5 and the outer frame 4.

[0037] The technical solution of the utility model lowers the height of the protrusion 3, places the optical component 5 on the plate-shaped protrusion 3, and uses the support part 6 to support the outer frame 4 instead of the protrusion 3. Since the support part 6 is made of plastic, its processable thickness is thinner than that of metals such as aluminum alloy. In this way, there can be a larger space between the relative support parts 6, and then, under the premise of ensuring that the back panel 1, the outer frame 4, and the expansion gap remain unchanged, the distance between the edge of the visible area and the edge of the outer frame 4 can be reduced, thereby achieving a narrower frame. At the same time, since the protrusion 3 is located below the optical component 5, the thickness of the protrusion 3 will not affect the size of the optical component 5. Therefore, a protrusion 3 with a larger thickness can be set to support the optical component 5. In this way, the support for the optical component 5 can be made more stable. The support part 6 can be set at the four edges of the front, rear, left and right ends of the upper end of the back panel 1 (only the left and right ends are drawn in the figure) to provide more stable support for the optical component 5.

[0038] See also Figure 1 In one embodiment of the present invention, the support portion 6 is arranged at intervals on the top of the protrusion 3 .

[0039] In the technical solution of the utility model, the support part 6 is arranged at intervals on the top of the convex part 3, so that the overall weight of the display module can be reduced.

[0040] See also Figure 6 In one embodiment of the utility model, an end surface of the support portion 6 opposite to the optical component 5 is flush with the convex portion 3.

[0041] In the technical solution of the utility model, by making the end surface of the support part 6 opposite to the optical component 5 flush with the protrusion 3, a larger space can be created between the relative support parts 6, thereby allowing a larger light-emitting component 2 and optical component 5 to be installed while ensuring that the back panel 1, the outer frame 4, and the expansion gap 10 remain unchanged.

[0042] See also Figure 1 , Figure 2 and Figure 6 In one embodiment of the utility model, the display module further includes a support rod 8 , which is located below the optical component 5 to support the optical component 5 , and the support rod 8 is located between the light emitting component 2 and the protrusion 3 .

[0043] In the technical solution of the present utility model, since the density of the protrusion 3 made of aluminum alloy is relatively high, the weight of the same volume of aluminum alloy is higher than that of plastic, and the cost is also relatively high. Therefore, a support rod 8 is provided to replace a part of the protrusion 3 to support the optical component 5, which can reduce the weight on the one hand and reduce the production cost on the other hand. The support rod 8 is a long rod with a square or rectangular cross-section, which can have a larger contact area with the optical component 5 and a better supporting effect.

[0044] See also Figure 1 , Figure 2 and Figure 6 In one embodiment of the utility model, the display module also includes a connecting portion 7, one end of the connecting portion 7 is connected to an end surface of the supporting portion 6 opposite to the optical film, and the other end of the connecting portion 7 extends in a direction away from the supporting portion 6 and is connected to the supporting rod 8.

[0045] In the technical solution of the utility model, the supporting part 6, the connecting part 7 and the supporting rod 8 are connected together, which is convenient for installation on the protrusion 3. The upper end surface of the connecting part 7 can be flush with the upper end surface of the supporting rod 8. In this way, the upper end surface of the entire supporting rod 8 can be used to support the optical component 5. At this time, the number of the supporting rod 8 is one, and the connecting parts 7 on the same side are all connected to it. The supporting rod 8 can also be set on the lower end surface of the connecting part 7. In this way, the connecting part 7 supports the optical component 5, and the support rod 8 supports the connecting part 7. The connecting part 8 is plate-shaped.

[0046] See also Figure 1 , Figure 2 and Figure 6 In one embodiment of the utility model, the support portion 6, the connecting portion 7, and the support rod 8 are integrally formed.

[0047] In the technical solution of the present utility model, the support part 6, the connecting part 7 and the support rod 8 are integrally formed by an injection molding process, which is convenient for processing and installation.

[0048] See also Figure 1 , Figure 2 and Figure 6 In one embodiment of the utility model, the support portion 6, the connecting portion 7, the support rod 8 and the convex portion 3 are fixedly connected.

[0049] In the technical solution of the utility model, the back plate 1 and the convex part 3 are used as a part of the injection mold, and the support part 6, the connecting part 7, and the support rod 8 are directly injection-molded and fixed on the convex part 3. In this way, the fixation of the support part 6, the connecting part 7, and the support rod 8 is more stable, and the support part 6, the connecting part 7, and the support rod 8 can also be fixed to the convex part 3 by screws. This fixing method is faster than injection molding by using the back plate 1 and the convex part 3 as a part of the injection mold.

[0050] See also Figure 2 and Figure 4 In one embodiment of the utility model, a plurality of buckles 301 are provided on the side of the protrusion 3, and a plurality of slots 401 corresponding to the buckles 301 are opened in the outer frame 4.
