The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" used herein includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The features of the embodiments and examples described below can be combined with each other without conflict.

Referring to FIG. 1, a first preferred embodiment of the present invention provides a display 100. The display 100 can be a display screen of an electronic device such as a mobile phone, a computer, a television, or a game machine. The display 100 includes at least a display panel 11 , a backlight module 10 , and a heat dissipation module 20 .

The display panel 11 can be a liquid crystal display panel. The backlight module 10 is disposed under the display panel 11 . The backlight module 10 includes a light guide plate 101, a light source 103, and a reflection sheet 105. The light source 103 is disposed adjacent to the light guide plate 101. In the present embodiment, the light source 103 is a point light source, such as a light emitting diode, such that the light source 103 generates a point heat source. The reflective sheet 105 is disposed directly on a surface of the light guide plate 101 away from the display panel 11 .

Referring to FIG. 2 and FIG. 3 , FIG. 2 is a schematic side view of the heat dissipation module 20 , and FIG. 3 is a schematic top view of the heat dissipation module 20 . The heat dissipation module 20 includes a heat sink 21 and a buffer member 23 . The heat dissipating member 21 is formed in a sheet shape, and the heat dissipating member 21 is directly disposed on a surface of the reflecting sheet 105 away from the light guiding plate 101 and disposed corresponding to the light source 103. That is, the heat sink 21 is disposed on a side of the light source 103 away from the display panel 11. In the embodiment, the size of the heat sink 21 is smaller than the size of the reflective sheet 105. Of course, in other embodiments, the shape and size of the heat dissipating member 21 may be adjusted as long as the area of the heat dissipating member 21 is larger than the area of the light source 103.

In the embodiment, the heat dissipating member 21 is a sheet-shaped heat dissipating material. In this way, the heat dissipating member 21 can diffuse heat of the point heat source generated by the light source 103 to achieve temperature reduction, thereby solving the heat dissipation problem of the point heat source. In order to improve the heat dissipation performance of the heat dissipating member 21, the heat dissipating member 21 may be made of a heat dissipating material having a good thermal conductivity such as a graphite sheet or a copper foil. Preferably, the heat sink 21 has a thickness ranging from 0.01 mm to 0.2 mm.

The cushioning member 23 is substantially in the form of a sheet. The buffer member 23 is directly disposed on a surface of the heat dissipation member 21 and the reflection sheet 105 away from the light guide plate 101. In the embodiment, the shape and size of the cushioning member 23 substantially match the display panel 11. The cushioning member 23 is made of a soft material that is self-contained with a slight viscosity and elasticity. Thus, the buffering member 23 is adhered to the surface of the heat dissipating member 21 and the reflecting sheet 105 away from the light guide plate 101 by its adhesive action. For example, when the size of the heat sink 21 is smaller than the size of the reflective sheet 105, the portion of the buffer member 23 corresponding to the heat sink 21 is directly pasted with the surface of the heat sink 21 away from the light guide plate 101. The other portions are in direct contact with the surface of the reflection sheet 105 away from the light guide plate 101.

In the present embodiment, the cushioning member 23 is a self-adhesive foam, such as acrylic foam. In the present embodiment, the viscosity of the cushioning member 23 ranges from 0.01 N/25 mm to 3 N/25 mm, that is, the force value required when the cushioning member 23 having a standard length of 25 mm is torn off.

It can be understood that, in the embodiment, the buffering member 23 directly adheres the heat dissipating member 21 to the reflective sheet 105 by its own viscosity, and is disposed corresponding to the light source 103. In this way, the point heat source generated by the light source 103 can be uniformly dissipated, and no additional adhesive is needed, which can effectively reduce the thickness of the display 100 and reduce the manufacturing cost thereof. In addition, due to the micro-adhesive property of the cushioning member 23, the cushioning member 23 is easily torn off from the backlight module 10, so that the rework is easy. At the same time, the cushioning member 23 is an elastic and soft material. Compared with the heat dissipating member 21 and the reflecting sheet 105, the foaming layer is bonded to the heat dissipating member 21 and the reflecting sheet 105. The display 100 is prevented from generating water ripples, and the buffering effect is better. Secondly, the thermal expansion and contraction of the cushioning member 23 is not conspicuous, and thus the thermal expansion of the reflecting sheet 105 is not restricted.

Referring to FIG. 4, a second preferred embodiment of the present invention provides a display 200. The display 200 includes a display panel 11 , a backlight module 10 , and a heat dissipation module 20 . It will be appreciated that the display 200 differs from the display 100 in that the display 200 further includes a metal frame 106. The metal frame 106 includes a bottom plate 107 and a side frame 108. The bottom plate 107 is disposed directly on a surface of the reflective sheet 105 away from the light guide plate 101. The side frame 108 is disposed on a periphery of the bottom plate 107, is substantially perpendicular to the bottom plate 107, and extends from a periphery of the bottom plate 107. In this manner, the side frame 108 and the bottom plate 107 together define a receiving portion 109 for receiving the light guide plate 101, the light source 103 and the reflection sheet 105.

In the embodiment, the heat dissipating member 21 is directly disposed on a surface of the bottom plate 107 away from the reflective sheet 105. The buffer member 23 is affixed to the surface of the heat sink 21 and the bottom plate 107 away from the reflective sheet 105. For example, a portion of the buffer member 23 corresponding to the heat dissipating member 21 is directly in adhesive contact with a surface of the heat dissipating member 21 away from the reflective sheet 105, and other portions are directly away from the reflective sheet 105 of the bottom plate 107. The surface is pasted into contact.

Obviously, in the display device 100/200 of the present invention, the buffer member 23 directly adheres the heat dissipating member 21 to the reflective sheet 105 or the metal frame 106 away from a surface of the light guide plate 101 by self-adhesiveness. There is no need to use the adhesive, which can effectively reduce the thickness of the display 100/200 and reduce its cost. At the same time, the cushioning member 23 is an elastic soft material. Compared with the adhesive layer, a foam layer is adhered to the backlight module 10, and the bonding is smoother, and no air bubbles are generated. The display 100/200 produces water ripples and has a good cushioning effect.

The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to be limiting, and the present invention is described in detail with reference to the preferred embodiments, and those skilled in the art should understand that the technical solutions of the present invention may be modified or substituted. Without departing from the spirit and essence of the technical solutions of the present invention.
