Description

Technical Field

[0002] At present, LCD display modules are mainly divided into two modes: side-entry modules and direct-down modules according to different light entry methods. The side-entry modules are mainly composed of backlight components and panel components. The backlight component mainly provides light source for the display module. The general structure includes backplane, middle frame, heat dissipation aluminum strip, LED lamp, optical film, reflective paper, protective cover, light guide plate and auxiliary materials. The backplane is the most basic existence of the backlight component. All parts are assembled on this basis. Its importance is self-evident. With the iterative update of market demand, light, thin, large size and high brightness have become the first choice for many users. However, with the increase in size and brightness, the thickness of the backplane needs to reach more than 1.2mm to meet the basic strength requirements.

[0003] However, since the backplane is not made of aluminum, the weight of the backplane accounts for more than 50% of the weight of the module, which cannot meet the customer's demand for lightness and thinness. In addition, the increase in brightness requires a high-power LED lamp, and the heat dissipation effect of the existing backplane cannot meet the requirements. Therefore, most modules will add heat dissipation aluminum strips to assist in heat dissipation, resulting in an increase in the number of internal components of the module, an increase in weight, and a higher cost, which makes the module lose competitiveness after entering the market; furthermore, due to the solidification of the module structure, the structure of the backplane is almost the same, and the four sides are bent to fit the middle frame, resulting in insufficient edge distance for fixing the diaphragm. Six to eight sets of molds are required to make the backplane, which is expensive. After the edge of the diaphragm is clamped and fixed between the backplane and the middle frame, when the internal temperature drops, the diaphragm will shrink and fall out, resulting in poor quality of the display module.

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0037] See also Figures 1 to 7As shown, the embodiment of the utility model discloses a display module, including a back plate 10, an optical component 20, a middle frame 30 and at least two positioning components 40. The back plate 10 is formed by extruding a heat dissipation profile. The back plate 10 made of heat dissipation material has a heat dissipation function itself, and no heat dissipation aluminum strip is needed for heat dissipation. The optical component 20 includes a diaphragm 21, a light guide plate 22 and a reflective paper 23 stacked in sequence. The reflective paper 23 is fixed on the back plate 10. At least one lug 211 is respectively provided at both ends of the diaphragm 21. The lugs 211 at both ends of the diaphragm 21 are both located outside the light guide plate 22. The lugs 211 are penetrated by a limit Hole 2111, the limiting hole 2111 is a rectangular structure, one end of the middle frame 30 is snap-connected with the back plate 10, and the other end is provided with at least two limiting grooves 31, the positioning component 40 includes a hanging ear 41 and at least one fastener 42, one end of the hanging ear 41 is installed on the back plate 10 through the fastener 42, and the other end passes through the limiting hole 2111 and is inserted into the limiting groove 31, so that the diaphragm 21 can be positioned. When the internal temperature of the display module is lowered, the diaphragm 21 will not separate from the hanging ear 41 even if it shrinks, which can effectively prevent the diaphragm 21 from jumping off. The heat dissipation profile can be aluminum, and the fastener 42 can be a screw.

[0038] The back panel 10 is formed by an aluminum extrusion die, with a simple cross-section and low mold cost. The strength of the back panel 10 can be ensured by selecting materials that are not too thick according to the required size. Generally, a thickness of 1.2T, 1.5T or above is selected. The aluminum extruded back panel 10 has some advantages that the stamped back panel 10 cannot meet. First, the aluminum extrusion die will not increase the cost of the die due to size restrictions. Secondly, compared with the stamped back panel 10, the manufactured back panel 10 has higher product precision, and the back panel 10 made of heat dissipation material is light in weight, which can meet the customer's needs for a thin and light display module.

[0039] Since the back panel 10 adopts an aluminum extrusion die, it is impossible to directly design and manufacture the ear 41 on the back panel 10, and there is a problem of the diaphragm 21 jumping off. Therefore, it is necessary to punch some holes on the aluminum extruded back panel 10 to place the ear 41 externally. In this embodiment, the ear 41 includes a base plate 411 and a positioning plate 412 vertically connected to one end of the base plate 411. The positioning plate 412 and the base plate 411 form an "L"-shaped structure. The base plate 411 is penetrated by at least one placement hole 4111, and at least one threaded hole 11 is penetrated at both ends of the back panel 10. The fastener 42 passes through the placement hole 4111 and is installed on the threaded hole 11. The positioning plate 412 passes through the limiting hole 2111 and is inserted into the limiting groove 31 to limit the diaphragm 21.

[0040] The ear 41 also includes at least one positioning column 413, which is protruding from the side of the bottom plate 411 away from the diaphragm 21. At least one first positioning hole 12 is also penetrated at both ends of the back plate 10. Two positioning columns 413 are fixed to the bottom of each bottom plate 411. The positioning columns 413 are inserted into the first positioning holes 12 to realize the pre-positioning of the ear 41 on the back plate 10, and finally fixed with fasteners 42. In this way, the diaphragm 21 and the light guide plate 22 can be limited. According to the size of the diaphragm 21, the number of positioning components 40 is also different.

[0041] In some embodiments, the placement hole 4111 is disposed on the bottom plate 411 , and the placement hole 4111 is a notch of a U-shaped structure, so that the hanging ear 41 can be quickly removed without removing the fastener 42 , thereby realizing quick disassembly and assembly of the hanging ear 41 .

[0042] Please read further Figure 1 to Figure 2 ,as well as Figures 5 to 9 In this embodiment, the middle frame 30 includes a side arm 32 and a frame body 33 vertically connected to one end of the side arm 32. The side arm 32 is snapped with the back plate 10. The back plate 10 is made of aluminum extrusion and is snapped with the middle frame 30 without buckles on all sides. The back plate 10 and the middle frame 30 are fixed by snapping, which can ensure the fit between the back plate 10 and the middle frame 30. The frame body 33 is provided with the limiting groove 31 on one side facing the diaphragm 21. The positioning plate 412 passes through the limiting hole 2111 and is inserted into the limiting groove 31.

[0043] The middle frame 30 is made of plastic material, which can ensure that the side arm 32 has a certain flexibility. The side arm 32 includes a side plate 321, at least one inner buckle 322, at least one pressing block 323 and at least one positioning block 324. The frame 33 is connected to one end of the side plate 321. The inner buckle 322 and the pressing block 323 are both arranged on one side surface of the side plate 321. The distance from one end of the pressing block 323 away from the frame 33 to the frame 33 is smaller than the distance from the inner buckle 322 to the frame 33. The inner buckle 322 and the pressing block 323 form a height difference. The positioning block 324 is convexly arranged on one end of the pressing block 323 away from the frame 33. The back plate 10 is clamped at Between the inner buckle 322 and the pressure block 323, the pressure block 323 abuts against the upper end surface of the back plate 10, and the inner buckle 322 abuts against the lower end surface of the back plate 10. The back plate 10 is also penetrated by at least one second positioning hole 13. The number of the pressure block 323, the positioning block 324, the inner buckle 322 and the second positioning hole 13 are all multiple. One positioning block 324, two pressure blocks 323 and two inner buckles 322 form a group. The inner buckle 322 is located between two adjacent pressure blocks 323. The positioning block 324 is inserted into the second positioning hole 13 to realize the side support arm 32 being clamped on the back plate 10, thereby strengthening the assembly strength of the middle frame 30 and the back plate 10.

[0044] Please read further Figure 1 , Figure 6 as well as Figures 10 to 13 In this embodiment, the back plate 10 includes two support plates 14 and a bending plate 15 that bulges toward the side close to the optical component 20. The two support plates 14 are respectively connected to the sky side and the ground side of the bending plate 15, and each positioning component 40 is respectively installed on the left and right sides of the bending plate 15.

[0045] The display module also includes two light bars 50, and the back panel 10 also includes two folded edges 16. The folded edges 16 are protruding from one end of the support plate 14 away from the bending plate 15. The two folded edges 16 are both arranged on the side of the support plate 14 facing the frame 33. There are no folded edges 16 on both sides of the aluminum extruded back panel 10. The two light bars 50 are respectively installed on the two folded edges 16. The light bar 50 is arranged corresponding to the light guide plate 22. The aluminum extruded back panel 10 has a simple structure and is suitable for large flat surfaces. Therefore, it is only suitable for making Edge models. The light bar 50 is attached to the sky side or the ground side. The number of light bars 50 can be varied according to the size.

[0046] The display module also includes a panel, which is mounted on the middle frame 30. The panel is located on the side of the diaphragm 21 away from the light guide plate 22. The light bar 50 includes a light board 51 and a plurality of LED lights 52 fixed on the light board 51. The LED lights 52 are electrically connected to the light board 51. The light board 51 is fixed on the folded edge 16. A strip-shaped support block 17 is protruded from the side of the support plate 14 facing the diaphragm 21. The support block 17 is located between the folded edge 16 and the bending plate 15. The support block 17 and the bending plate 15 both support the optical component 20. The LED lights 52 are arranged corresponding to the light guide plate 22. The light bar 50 emits light from the side of the light guide plate 22. Part of the light will propagate upward, and the other part of the light will propagate downward. The reflective paper 23 will deflect the downward light and propagate upward to form a dot matrix light. The diaphragm 21 will correct the propagation direction of the light and convert the dot matrix light into a plane matrix light. Finally, the light enters the panel, and the panel is powered on to produce a picture.

[0047] The display module also includes at least two buffer pads 60. A mounting groove 34 is provided on one side of the middle frame 30 facing the panel and on one side of the middle frame 30 facing the diaphragm 21. The two buffer pads 60 are respectively installed in the two mounting grooves 34. The panel and the diaphragm 21 correspond to the two buffer pads 60 respectively to reduce the impact force between the diaphragm 21 and the middle frame 30, and between the panel and the middle frame 30.

[0048] The utility model also discloses a display device, including the display module as described above. The display module is a cost-reducing display module design for some module models with small order requirements and large size. The back panel 10 is made of aluminum, and the mold is an aluminum extrusion mold, with only the upper and lower sides being left with bent edges. Compared with stamping molds, aluminum extrusion molds cost a lot. Secondly, aluminum itself has good heat dissipation performance, and there is no need to consider locking heat dissipation aluminum strips for auxiliary heat dissipation, which saves the mold cost of the back panel 10 and greatly reduces the development cost.

[0049] The assembly method of the display module includes the following steps:

[0050] Step S101, manufacturing a back plate 10, which is formed by extruding a heat dissipation profile, wherein the back plate 10 includes a bending plate 15, two support plates 14 and two folded edges 16, the two support plates 14 are respectively connected to the sky side and the ground side of the bending plate 15, the folded edges 16 are connected to one end of the support plate 14 away from the bending plate 15, and the two folded edges 16 are respectively on the sky side and the ground side of the back plate 10;

[0052] Step S103, assembling the optical component 20, installing the reflective paper 23, the light guide plate 22 and the film 21 on the back plate 10 in sequence, and inserting the positioning plate 412 on the hanging ear 41 into the limiting hole 2111 on the film 21;

[0053] Step S104, assembling the light bar 50, installing the light bar 50 on the folded edge 16 of the back plate 10, and placing the LED lights 52 on the light bar 50 facing the light guide plate 22;

[0055] Step S106 , assembling the panel, bonding the buffer pads 60 in the two mounting grooves 34 respectively, fixing the panel on the middle frame 30 , and placing the panel close to the diaphragm 21 and abutting against one of the buffer pads 60 .

[0056] Beneficial effects of display module:

[0057] 1. The back panel 10 is changed from stamping to aluminum extrusion, which reduces the mold cost. The mold is reduced from 7 sets to 1 to 2 sets, which effectively solves the problem of being unable to produce due to the size being too large and the machine being unable to meet the size;

[0058] 2. The heat dissipation profile used in the back panel 10 is not limited to aluminum, as long as it is an extruded material with heat dissipation function, the back panel 10 itself has a heat dissipation function, and there is no need to use heat dissipation aluminum strips for heat dissipation;

[0059] 3. The back plate 10 made of heat dissipation material is light in weight and can meet the customer's demand for thinner and lighter display modules;

[0060] 4. The positioning component 40 can position the diaphragm 21. When the internal temperature of the display module decreases, the diaphragm 21 will not be separated from the hanging ear 41 even if it shrinks, which can effectively prevent the diaphragm 21 from jumping off.

[0061] To sum up, the back panel 10 of the utility model is made of a heat dissipation profile. The back panel 10 itself has a heat dissipation function and does not need to use heat dissipation aluminum strips for heat dissipation. The back panel 10 made of heat dissipation material is light in weight and can meet the customer's needs for a thin and light display module; and the back panel 10 is formed by extrusion molding, does not require injection molding and stamping, requires a small number of molds, and has low cost.
