To describe the embodiments of the present application or solutions in prior art more clearly, a brief description of the drawings for the embodiments of the present application will be given below. It is apparent that the drawings in the description below illustrate some of the embodiments of the present application, and other drawings may be obtained by those of ordinary skill in the art based on these drawings without any creative effort.
In order to at least describe the purposes, solutions, and advantages of the embodiments of the present application more clearly, the solutions in the embodiments of the present application are described below in combination with the drawings for the embodiments. It is apparent that the embodiments in the following description are some embodiments but may not be all of the embodiments of the present application. In view of the embodiments in the present application, other embodiments that, for example, may be obtained by a person of ordinary skill in the art without any creative effort, shall fall within the protection scope of the present application.
Conventional approaches like the spliced rubber frame and the integrated rubber frame are used when the liquid crystal panel and optical components are fixed by the rubber frame in related art, where a thickness of a main body of the rubber frame has a direct impact on the overall size of the backlight module, thereby causing a thickness of a display device to be thicker.
In view of this, the present application provides a display device to reduce the thickness of the backlight module, to improve production efficiency of the backlight module and at the same time reduce costs.
In embodiments, the display device may also include a front frame 5, which is connected to the outside of the backplane 1
As shown in
The display device according to the present embodiments may be a liquid crystal television or a liquid crystal display and the like. As shown in
The display device provided by the present embodiments includes the backplane, the optical component group, the liquid crystal panel, and supporting members. The optical component group includes a plurality of optical components laminated, and the optical component group is provided between the liquid crystal panel and the backplane. The backplane includes the bottom plane and the side planes respectively extended from the edge of the bottom plane to the side of the bottom plane. The supporting members are provided in at least two corners of the backplane, and the liquid crystal panel is disposed on a side of the supporting members that is away from the bottom plane. By disposing supporting members in at least two corners of the backplane, the liquid crystal panel is supported and fixed, thereby reducing the thickness of the backlight module in the display device. So, the thickness of the display device is less.
In embodiments, a concavity 112 is formed between the protrusion 111 and the side plane 12, that is, the bottom plane 11 further includes the concavity 112 between the protrusion 111 and the side plane 12. The concavity 112 is configured to house the supporting member 4 or any other structure.
In embodiments, in order to secure the liquid crystal panel in all directions, the number of supporting members 4 is generally four, and the supporting members 4 are disposed in one-to-one correspondence with the corners of the backplane 1.
Meanwhile, since the liquid crystal panel 3 is located on the supporting members 4, with four corners of the liquid crystal panel 3 in direct contact with the four supporting members 4, the supporting members 4 is able to fixate the liquid crystal panel 3, and support the liquid crystal panel 3. Therefore, by using four supporting members 4 to fixate the four corners of the liquid crystal panel 3, a better support and fixation are provided to the liquid crystal panel 3, so that a firmer installation and a higher flatness of the liquid crystal panel 3 are achieved.
Furthermore, two supporting members 4 may be used. The two supporting members 4 may be mounted at two of the four corners of the backplane 1 which are centrosymmetric. Due to two set of diagonal corners that are centrosymmetric, the two supporting members 4 need to be disposed by selecting one set of corners. Specifically, details concerning the use of two supporting members 4 are similar to those of using four supporting members 4, which will not be described again.
The supporting members 4 may have several different structures and forms. As a manner, the supporting member 4 includes a first extension portion 41 and a second extension portion 42, which are respectively disposed on two adjacent edge portions of the backplane 1.
As shown in
Since the first extension portion 41 and the second extension portion 42 are respectively located on two adjacent edge portions of the corner of the backplane 1, the first extension portion 41 and the second extension portion 42 may be configured to fix the liquid crystal panel 3 and constrain the optical component group 2 within the space formed by the four supporting members 4. At this time, the liquid crystal panel 3 is constrained by the supporting members 4 in both lengthwise direction and widthwise direction of the backplane, e.g., the liquid crystal panel 3 is limited in a direction perpendicular to the thickness direction thereof, so that the liquid crystal panel 3 may not move in the direction perpendicular to the thickness direction thereof. Similarly, the optical component group 2 located inside the supporting members 4 is fixated by either the first extension portions 41 or the second extension portions 42 of the supporting members 4, so that the position of the optical component group 2 is constrained.
For ease of manufacture and installation, the first extension portion 41 and the second extension portion 42 of the supporting member 4 generally have the similar structure. To ensure that the first extension portion 41 and the second extension portion 42 have a sufficient bearing capacity for the liquid crystal panel 3, and reduce the sizes of the supporting members 4 so as to reduce cost, as shown in
In order to fix the supporting members 4 onto the backplane 1, the supporting members 4 may be attached to the backplane 1 in various detachable or non-detachable manners. In embodiments, the supporting members 4 and the backplane 1 may be snap-fitted.
As shown in the partial enlarged view in
In embodiments, at least one first snapping portion 43 is provided in the supporting member 4, and at least one second snapping portion 121 is provided in the side plane 12 to snap or engage with the corresponding first snapping portion 43. The second snapping portion 121 and the first snapping portions 43 are in one-to-one correspondence.
In this case, the attachment of the supporting members 4 and the backplane 1 may be realized by means of threaded fasteners or bonding method, and is not limited here.
In embodiments, the first snapping portion 43 may be a projection and the second snapping portion 121 may be a notch into which the projection is snapped; or, the first snapping portion 43 may be the notch and the second snapping portion 121 may be the projection snapped into and coupled with the notch. Notches and projections are easy to be made on the side plane 12 due to the thinness of the backplane 1, and notches and projections are also easy to be made on the supporting members 4. Therefore, the snap-fit connection of the supporting member 4 and the side plane 12 is easily realized by the first snapping portion 43 of the supporting member 4 which is the projection or the notch and the corresponding second snapping portion 121 of the side plane 12 which is the notch or the projection, thereby ensuring the reliability of the attachment of the supporting members 4 and the side plane 12. The shape and quantity of the first snapping portion and the second snapping portion are not limited in the application as long as the snap-fit connection is realized.
In embodiments, for example, the first snapping portion 43 is the notch and the second snapping portion 121 is the projection that is snapped into and coupled with the notch.
In order to firmly support the liquid crystal panel 3, in embodiments, the supporting member 4 includes a first settling surface 44 that faces toward the light emitting side of the display device, and the liquid crystal panel 3 is placed on the first settling surface 44.
As shown in
The protrusions 111 are abutted against a side of the optical component group 2 that away from the liquid crystal panel 3, and the protrusions 111 are configured to support the optical component group 2. The protrusions 111 are located on the edge portions of the backplane 1 which is close to the side planes, and are in contact with edges of a lowest component of the optical component group 2.
In embodiments, the top end of the protrusion 111 is formed into a second settling surface for supporting the optical component group 2. As mentioned above, the top ends of the protrusions 111 are in contact with edges of the lowest component of the optical component group, i.e., the protrusions 111 are in contact with the edges of the surface of the lowest optical component. Therefore, the top ends of the protrusions 111 are formed into the second settling surfaces for abutting against the lowest optical component, which provides sufficient support for the optical components. In embodiments, the second settling surfaces are configured to support the optical component group 2 including the lowest optical component and various laminated optical components stacked upon the lowest component.
In order to provide additional support to the supporting member 4, in embodiments, a side portion of the supporting member 4 that is away from the side plane 12 may be on the second settling surface.
As shown in
It should be noted that the side portion of the supporting member 4 that is away from the side plane 12 is on the second settling surface. The edge portion of the optical component group 2 is also on the second settling surface. The liquid crystal panel 3 is provided on the first settling surface 44. The bottom surface of the optical component group 2 and a bottom surface of the side portion of the supporting member 4 that is away from the side plane 12 are in a same plane. Accordingly, the optical component group 2 is wholly located within the space formed by the four supporting members 4, which greatly reduces a gap between the liquid crystal panel 3 and the optical component group 2 and makes the thickness of the whole display device to become thinner.
In embodiments, the supporting member 4 includes a supporting portion 45 extended towards the bottom plane 11 of the display device and abutted against the bottom plane 11 of the backplane 1.
As shown in both
In embodiments, the thickness of the supporting portion 45 is matched with the width of the concavity 112, so that the supporting portion 45 may be embedded into the concavity 112, so as to achieve the fixation of the supporting members 4 and the backplane 1.
The side portion of the supporting member 4 that is away from the side plane 12 is fixed between the backplane 1 and the liquid crystal panel 3. For example, the side portion is between the protrusion 111 and the liquid crystal panel 3. Therefore, the supporting members 4 are more stable in the display device through the supporting effect of the bottom surface of the backplane 1 for the supporting portions 45.
In embodiments, the optical component group 2 includes a reflector 21, a diffusion plate 22, and multiple optical film sheets 23 provided sequentially from a back surface to a front surface of the display device.
In embodiments, hangers 13 are provided on the side plane 12 of the backplane 1. Through-holes through which the hangers 13 are passed are provided on the edge portions of the optical film sheets 23. The optical film sheets 23 are fixated on the backplane 1 through the hangers 13.
As shown in
Since the optical film sheets 23 are the uppermost of the optical component group 2, the optical film sheets 23 are closest to the liquid crystal panel 3. But, the optical film sheets 23 are not in tight contact with the liquid crystal panel 3. So in order to avoid a relative displacement between the optical film sheets 23 and the diffusion plate 22, the optical film sheets 23 are fixed onto the backplane 1 by making the hangers 13 of the backplane 1 to pass through the through-holes of the optical film sheets 23.
In embodiments, the supporting members 4 may be made of plastic for ease of manufacture. Specifically, the supporting members 4 may be made of plastic, preferably hard plastic, to ensure a stationarity of the structure of the supporting members 4, thereby ensuring the limitative effect on the optical component group 2 and the supportive effect on the liquid crystal panel 3.
Moreover, the supporting members are made of the plastic material that may be the same as the material of the conventional rubber frame. And since the supporting members 4 only occupy four corners of the backplane 1, there is much less material than the rubber frame 300, which effectively reduces the cost of manufacture of the display device. Besides, the supporting members 4 are attached to the backplane 1 through the snap-fit connection, and no crumbs will emerge due to the fraction between the rubber frame 300 and the backplane 1 during installation. Since the supporting members 4 are small in size, the supporting members 4 are more easily engaged with the backplane 1. Compared with the rubber frame 300, the supporting members 4 not only reduce the overall thickness of the display device but also increase the quality and productiveness of the display device.
Finally, in embodiments, a specific method that calculates a minimal thickness of the display device is provided. As shown in
In embodiments, the display device includes the backplane, the optical component group, the liquid crystal panel, and supporting members. The optical component group includes a plurality of optical components laminated, and the optical component group is provided between the liquid crystal panel and the backplane. The backplane includes the bottom plane and the side planes respectively extended from the edge of the bottom plane to the side of the bottom plane. The supporting members are provided in at least two corners of the backplane, and the liquid crystal panel is disposed on a side of the supporting members that is away from the bottom plane. By disposing supporting members in at least two corners of the backplane, the liquid crystal panel is supported and fixed, thereby reducing the thickness of the backlight module in the display device. So, the thickness of the display device is less.
