This application claims priority to Chinese Patent Application No. 201710277599.7 filed on Apr. 25, 2017, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to ultra-thin television.
Ultra-thin televisions are popular. Usually, a thinner ultra-thin television is obtained by decreasing thicknesses of electronic components in the ultra-thin television, the electronic components can be liquid crystal display screen, power supply, or printed circuit boards. Improvement in the art is preferred.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the exemplary embodiments described herein. The drawings are not necessarily to scale and the proportions of certain sections have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The middle frame 3 is positioned on a side of the liquid crystal display screen 2 away from the front board 11. The middle frame 3 includes a front plate 31 and a plurality of side plates 32. The liquid crystal display screen 2 is between the front board 11 and the front plate 31. The front plate 31 and the plurality of side plates 32 cooperatively define a housing 33. The backlight element 4, the base board 5 and the radiating element 6 are all received in the housing 33.
The backlight element 4 is positioned on a side <please S&R> of the front plate 31 away from the liquid crystal display screen 2. The backlight element 4 includes at least one light source 41 and a light guiding plate 42.
In this exemplary embodiment, the backlight element 4 is a side entry backlight element, and the at least one light source 41 is positioned on a side of the light guiding plate 42, thus the at least one light source 41 is positioned between one of the plurality of side plates 32 and the light guiding plate 42.
The base board 5 is positioned on a side of the backlight element 4 away from the liquid crystal display screen 2.
The base board 5 includes a main body 51 and a metal plate 52 covering the main body 51, thus the main body 51 is in inner of the base board 5.
Preferably, the main body 51 is made of resin, or is made of metallic material, which is different from the material of the metal plate 52.
Preferably, the metal plate 52 is made of aluminum.
In this exemplary embodiment, the metal plate 52 includes a top metal sheet 521 near the backlight element 4, a bottom metal sheet 522 opposite to the top metal sheet 521 and away from the backlight element 4, a first side metal sheet 523 connecting the top metal sheet 521 and the bottom metal sheet 522, and two second side metal sheets 524 connecting the first side metal sheet 523. The first side metal sheet 523 position near one of the plurality of side plates 32 near the light source 41. The first side metal sheet 523 defines at least one opening 525. The base board 5 defines at least one radiating space 53 in inner portion thereof. Each of the at least one radiating space 53 extends to at least one metal sheet of the metal plate 52, and is in air communication with one of the at least one opening 525.
Preferably, the top metal sheet 521, the bottom metal sheet 522 are separately and seamlessly connect to the first side metal sheet 523 and the two second side metal sheets 524.
Preferably, each of the at least one radiating space 53 extends through the main body 51 of the base board 5, such as the at least one radiating space 53 extends to the top metal sheet 521 and the bottom metal sheet 522; alternatively, the at least one radiating space 53 extends to the two second side metal sheets 524; alternatively, each of the at least one radiating space 53 extends to the two second side metal sheets 524, the top metal sheet 521 and the bottom metal sheet 522.
In this exemplary embodiment, a number of the at least one radiating space 53 is one. The radiating space 53 extends to the top metal sheet 521, the bottom metal sheet 522, and the two second side metal sheets 524.
The radiating element 6 includes a first portion 61 and a second portion 62 connecting to the first portion 61 near the at least one opening 525. The first portion 61 is positioned on a side of the light source 41 away from the light guiding plate 42 and is in contact with the light source 41. The second portion 62 corresponds to and is received in the at least one radiating space 53, and is thus connecting to the metal plate 52.
In this exemplary embodiment, the second portion 62 connects to the top metal sheet 521, the bottom metal sheet 522, and the two second side metal sheets 524.
In this exemplary embodiment, the first portion 61 is positioned between the light source 41 and one side plate 32 near the light source 41.
Preferably, the first portion 61 seamlessly connects to the second portion 62.
In this exemplary embodiment, the first portion 61 substantially and perpendicularly connects to the second portion 62, for the backlight element 4 is a side entry backlight element.
The base board 5 can further include at least one locking element (not shown).
In this exemplary embodiment, two outermost side radiating spaces 53a separately extend to the two second side metal sheets 524, thus two outermost side branches 621 separately and closely connect to the two second side metal sheets 524.
In other exemplary embodiments, the radiating spaces 53a can be arranged in a different pattern.
A thickness of the ultra-thin television 100 (100a) is decreased by positioning the second portion 62 into the radiating spaces 53 in the base board 5. Heat from the light source 41 can be dissipated through the first portion 61, the second portion 62, and the metal plate 52.
The exemplary embodiments shown and described above are only examples. Many details are often found in the art such as the other features of an ultra-thin television. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the sections within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the exemplary embodiments described above may be modified within the scope of the claims.
