DETAILED DESCRIPTION
Hereinafter, the invention will be explained in detail with reference to the accompanying drawings.
The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.
It will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the invention.
Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. In an exemplary embodiment, when the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms, “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value.
Unless otherwise defined, all terms (including 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. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Exemplary embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. In an exemplary embodiment, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.

Thus, the mold frame 300 surrounds the display panel 200 and the backlight unit 400.
A top cover combining groove 312 and a weight reduction groove 314 are defined in the mold frame upper surface 310. The top cover combining groove 312 receives the top cover protrusion 122 of the top cover 100, so that the top cover 100 and the mold frame 300 may be combined together. In an exemplary embodiment, the top cover protrusion 122 and the top cover combining groove 312 may be combined with each other in interference fit manner. Thus, the top cover protrusion 122 may be slightly larger than the top cover combining groove 312. Accordingly, the top cover 100 and the mold frame 300 may be firmly combined together.
The weight reduction groove 314 may lower a weight of the mold frame 300, and may reinforce strength of a structure. In an exemplary embodiment, the weight reduction groove 314 may be defined in the mold frame lower surface 320, the mold frame inner surface 330 and the mold frame outer surface 340, as well as in the mold frame upper surface 310.
The mold frame upper surface 310 makes contact with the top cover lower surface 120 of the top cover 100. In an exemplary embodiment, a boundary shape of the mold frame 300 in a plan view may be substantially same as that of the top cover 100.

The light guiding plate 410 is disposed under the display panel 200. The light guiding plate 410 guides the light from the light source to the display panel 200. The light guiding plate 410 converts incident light having a light distribution of the spot light source or the line light source to exiting light having a light distribution of a surface light source. Thus, the light guiding plate 410 guides the light from the light source toward the display panel 200. Although the light guiding plate 410 is described having uniform thickness in the illustrated exemplary embodiment, the invention is not limited thereto, and the light guiding plate 41 may have various shapes. In an exemplary embodiment, the light guiding plate 410 may have a wedge shaped cross section, for example. In an exemplary embodiment, a thickness of the light guiding plate 410 may be smaller as far from the light source to provide the wedge shaped cross section.
The optical element 420 is disposed on the light guiding plate 410. The optical element 420 may improve optical property of the light from the light guiding plate 410. Thus, the optical element 420 may provide uniform brightness of the light from the light guiding plate 410. In an exemplary embodiment, the optical element 420 may include plurality of optical sheets. In the exemplary embodiment, optical element 420 may include a protecting sheet, a prism sheet and a diffusion sheet, for example.

In an exemplary embodiment, the light source may include a plurality of light emitting diode (“LED”) light sources, and may be a spot light source or a line light source generating the light.
The reflecting plate 430 is disposed under the light guiding plate 410. Thus, the reflecting plate 430 is disposed between the light guiding plate 410 and the bottom cover 500. The reflecting plate 430 reflects light from a bottom surface of the light guiding plate 410 which is opposite to the light exiting surface of the light guiding plate 410 toward the display panel 200, so that luminous efficiency may be improved.
The bottom cover 500 is disposed under the mold frame 300. The bottom cover 500 may be combined with the mold frame 300 to receive the backlight unit 400.
The bottom cover 500 includes a bottom cover upper surface 510 and a bottom cover lower surface 520 which is opposite to the bottom cover upper surface 510. A bottom cover protrusion 512 is provided on the bottom cover upper surface 510. Thus, the bottom cover protrusion 512 extends in the third direction D3. The bottom cover protrusion 512 is received in the bottom cover combining groove 322 of the mold frame 300, so that the bottom cover 500 and the mold frame 300 may be combined with each other.
In an exemplary embodiment, the bottom cover 500 may include a material having good impact resistance, such as plastic. In an exemplary embodiment, the bottom cover 500 may include polycarbonate and glass fiber, for example. In an exemplary embodiment, the bottom cover 500 may include a substantially same material as that of the mold frame 300. Thus, the top cover 100, the mold frame 300 and the bottom cover 500 may include substantially same material. In an exemplary embodiment, the bottom cover 500 may be provided by an injection molding method, for example.
According to the exemplary embodiment, a weight reduction groove, a top cover combining groove, and a bottom combining groove are defined in a surface of the mold frame of the display apparatus. In an exemplary embodiment, the mold frame may be provided by an injection molding method. The weight reduction groove, the top cover combining groove, and the bottom combining groove may be defined when the mold frame is provided. The top cover and the bottom cover include a top cover protrusion and a bottom cover protrusion. The top cover and the bottom cover may be combined with the top cover combining groove and the bottom combining groove of the mold frame, respectively. Accordingly, a receiving container having a simple structure compared with a traditional structure such as a hook connection, may be easy to rework, and good for dirt prevention.
