Technical Field

The invention belongs to the technical field of display panels, and particularly relates to an ultrathin display panel assembly and a manufacturing method thereof.

Background

With the development of science and technology, the television industry also blooms in multiple aspects, and the technology and materials are continuously reformed and innovated, so that the multi-angle and multi-dimensional development is achieved. At present, the edge folding structure of the back plate of the panel module is changed to realize a frame-free structure, the steel-plastic plate is the most favored material for manufacturing the back plate, and the strength and the flatness of the steel-plastic plate can replace the prior common steel materials to be combined into an integral application function after punch forming.

Fig. 1 is a schematic structural diagram of a conventional steel-plastic plate, which includes a metal plate with a thickness of 0.3-0.5mm as a face plate 01, a metal plate with a thickness of 0.3-0.5mm (coated with a protective coating on the back) as a bottom plate 03, and a plastic core layer 02 located between the face plate 01 and the bottom plate 03, wherein the face plate 01, the plastic core layer 02, and the bottom plate 03 are pressed together to form the steel-plastic plate.

Due to the influence of the plastic core layer 02 of the steel-plastic plate, the steel-plastic plate can not be subjected to punch forming like normal steel. In order to pursue beauty, lightness and thinness of a television, a power supply assembly needs to be locked and hidden on the back face of a supporting back plate of the television, and because a rigid plastic plate cannot be subjected to structures such as convex hull forming, flanging and bud sprouting and the like, a single steel is used in the industry at present to form a required functional structural member through punch forming, and then the steel-plastic plate is locked and attached through screws.

Fig. 2 is a schematic structural diagram of a conventional display panel assembly, which includes a display screen 10, a plastic-steel plate 20 for supporting the display screen 10, a foam adhesive 30 for connecting the display screen 10 and the plastic-steel plate 20, a hardware support plate 40 located below the plastic-steel plate 20, a fixing bolt 54 for fixing the hardware support plate 40, a power board 51, a control board 52, a core board 53, and a rivet structure 60 for fixedly connecting the plastic-steel plate 20 and the hardware support plate 40, wherein the power board 51, the control board 52, and the main board 53 are all fixed below the hardware support plate 40; the outer periphery of the steel-plastic plate 20 is flanged or bent to form a bending structure 21 for supporting the display screen 10.

The hardware support plate 40 is formed to form a convex hull 41 and a flanging and bud-forming structure 42 located on the convex hull 41, and a fixing member (not shown) fixes the power supply board 51, the control board 52 and the main board 53 through the flanging and bud-forming structure 42.

The existing display panel assembly still needs a hardware support plate, which causes cost increase and is not beneficial to the ultrathin display panel.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention discloses an ultrathin display panel assembly, which comprises a display screen 1, a steel-plastic plate 2 for bearing the display screen 1, foam rubber 3 for connecting the display screen 1 and the steel-plastic plate 2, a hardware assembly and a bolt 7 for fixing the steel-plastic plate 2, wherein the hardware assembly is a hardware assembly of a module of the display panel assembly and comprises a power supply board 4, a control board 5 and a machine core board 6, and the hardware assembly is fixed below the steel-plastic plate 2, as shown in figure 3.

In other embodiments, the hardware components may be a combined board that integrates power, control, and chip.

The steel-plastic plate 2 is formed into a convex hull 21 and a flanging and sprouting structure 22 positioned on the convex hull 21, and the flanging and sprouting structure 22 is used for fixing and respectively fixing the power panel 4, the control panel 5 and the core board 6 below the steel-plastic plate 2.

In the present embodiment, the power board 4, the control board 5 and the core board 6 are fixed by at least two flanging bud structures 22.

As shown in fig. 4 and 5, the steel-plastic plate 2 comprises an inner metal plate 201, a plastic core layer 202 and an outer metal plate 203 which are pressed together, wherein the length and width of the inner metal plate 201 are the same as those of the plastic core layer 202, respectively, so that the edges of the inner metal plate 202 and the plastic core layer 202 are attached; the length and width of the outer metal plate 203 are greater than the length and width of the inner metal plate 201 and the plastic core 202, respectively (i.e. the length of the outer metal plate 203 is greater than the length of the inner metal plate 201 and the length of the plastic core 202, and the width of the outer metal plate 202 is greater than the width of the inner metal plate 201 and the width of the plastic core 202), and the inner metal plate 201 and the plastic core 202 are located inside the outer metal plate 203.

In order to make the steel-plastic plate 2 lock the hardware components (the power board 4, the control board 5 and the core board 6) required by the module of the display panel assembly, the plastic property of the plastic core layer 202 needs to be weakened, and the rigidity of the steel-plastic plate 2 needs to be enhanced.

The thickness of the outer metal plate 203 is preferably 0.3-0.5mm, and the outer metal plate 203 is made of other appearance materials such as VCM plate materials, aluminum materials, stainless steel and the like; the plastic core layer 202 is made of ABS, PC, ABS + PC, PP honeycomb plate and other light and thin materials; the thickness of the inner metal plate 201 is preferably 5-10 μm, and the material of the inner metal plate 201 is aluminum material, stainless steel or other bonding material; the total thickness of the steel-plastic plate, which is conditioned by the thickness of the plastic core layer 202, is preferably 1.2-5.0 mm.

The inner metal plate 201 is provided with at least one inner opening 2011, the plastic core layer 202 is provided with a plastic opening 2021 corresponding to the inner opening 2011, the size of the inner opening 2011 is not larger than the size of the plastic opening 2021 (namely, the projection of the inner opening 2011 on the outer metal plate 203 is located inside the projection of the plastic opening 202 on the outer metal plate 203), the inner opening 2011 and the plastic opening 2021 are vertically arranged correspondingly, and the inner opening 2011 and the plastic opening 2021 are located in an area corresponding to a hardware component.

Because the inner metal plate 201 and the plastic core layer 202 respectively cut the inner metal plate material in the inner opening 2021 and the plastic material in the plastic opening 2021, the weight of the inner metal plate 201 and the plastic core layer 202 is reduced, and particularly the material of the plastic core layer 202 is partially removed, so that the plastic application of the material in the processing area of the outer metal plate 203 (i.e., the area where the outer metal plate 203 is larger than the inner metal plate 201 and the plastic core layer 202) can be synchronously widened while the strength of the inner metal plate 201 and the plastic core layer 202 is ensured and the plastic function of the metal plate can be kept.

As shown in fig. 3, at least one inside opening 2011 and one plastic opening 2021 are provided in the corresponding area of the hardware component (such as the power board 4, the control board 5, and the core board 6) and the steel-plastic board, so that the convex hull 2031 and the flange sprout-forming structure 2032 on the convex hull 2031 are formed only on the outside metal board 203 in the corresponding area of the inside opening 2011 and the plastic opening 2021, and the power board 4, the control board 5, and the core board 6 are fixed by a fixing member (not shown) through the flange sprout-forming structure 2032.

The area of the outer metal plate 203 larger than the inner metal plate 201 and the plastic core layer 202 is a processing area 2033, and the processing area 2033 is subjected to plastic forming (specifically, the processing method includes convex hull forming, sprouting, flanging forming, stud riveting, round edge bending, edge folding, bending and the like) to form a bending structure for positioning the display screen 1 in the processing area 2033.

The inner metal plate 201 and the plastic core layer 202 may also have corresponding inner openings 2011 and plastic openings 2021 in areas that do not correspond to the hardware components, so as to achieve the purpose of removing the plastic core layer 202.

The steel-plastic plate is a five-in-one steel-plastic module backboard combining the hardware backboard, the middle frame, the front frame and the inner and outer supporting plates, and the ultra-thinning of the display panel assembly is achieved.

The invention also discloses a manufacturing method of the ultrathin display panel assembly, which comprises the following steps:

s1: providing an inner metal plate 201 and a plastic core layer 202 with the same size, and forming at least one inner opening 2011 and one plastic opening 2021 in the areas of the inner metal plate 201 and the plastic core layer 202 corresponding to hardware;

s5: the hardware assembly is fixed by a fixing piece (not shown) through a flanging and sprouting structure 2032, and the display screen 1 is positioned by the bending structure.

The invention solves the problem of hardware supporting plate removal, realizes that the module of the display panel assembly can be integrated with the hardware assembly required by the locking module only by the steel-plastic plate, reduces the weight and the cost of the display panel assembly, and achieves the aim of thinning.

The invention makes full use of the strength characteristic of the steel-plastic plate, can be used as the back plate of the display panel assembly, reduces the stamping and stretching cost for forming the back plate, and reduces the plastic forming function of the metal plate by improving the plastic core layer, and has the following advantages:
