The drawings illustrate exemplary embodiments of the inventive concept and, together with the description, serve to explain principles of the inventive concept. In the drawings:
Features of the inventive concept and methods of accomplishing the same may be understood more readily by reference to the following detailed description of embodiments and the accompanying drawings. Hereinafter, example embodiments will be described in more detail with reference to the accompanying drawings, in which like reference numbers refer to like elements throughout. The present invention, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the aspects and features of the present invention to those skilled in the art. Accordingly, processes, elements, and techniques that are not necessary to those having ordinary skill in the art for a complete understanding of the aspects and features of the present invention may not be described. Unless otherwise noted, like reference numerals denote like elements throughout the attached drawings and the written description, and thus, descriptions thereof will not be repeated. In the drawings, the relative sizes of elements, layers, and regions may be exaggerated for clarity.
It will be understood that, although the terms “first,” “second,” “third,” 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 used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section described below could be termed a second element, component, region, layer or section, without departing from the spirit and scope of the present invention.
Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of explanation 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 in operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.
It will be understood that when an element, layer, region, or component is referred to as being “on,” “connected to,” or “coupled to” another element, layer, region, or component, it can be directly on, connected to, or coupled to the other element, layer, region, or component, or one or more intervening elements, layers, regions, or components may be present. In addition, it will also be understood that when an element or layer is referred to as being “between” two elements or layers, it can be the only element or layer between the two elements or layers, or one or more intervening elements or layers may also be present.
In the following examples, the x-axis, the y-axis and the z-axis are not limited to three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the x-axis, the y-axis, and the z-axis may be perpendicular to one another, or may represent different directions that are not perpendicular to one another.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present 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 “comprises,” “comprising,” “includes,” and “including,” when used in this specification, specify the presence of the 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. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
As used herein, the term “substantially,” “about,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent deviations in measured or calculated values that would be recognized by those of ordinary skill in the art. Further, the use of “may” when describing embodiments of the present invention refers to “one or more embodiments of the present invention.” As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively. Also, the term “exemplary” is intended to refer to an example or illustration.
When a certain embodiment may be implemented differently, a specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially at the same time or performed in an order opposite to the described order.
The electronic or electric devices and/or any other relevant devices or components according to embodiments of the present invention described herein may be implemented utilizing any suitable hardware, firmware (e.g. an application-specific integrated circuit), software, or a combination of software, firmware, and hardware. For example, the various components of these devices may be formed on one integrated circuit (IC) chip or on separate IC chips. Further, the various components of these devices may be implemented on a flexible printed circuit film, a tape carrier package (TCP), a printed circuit board (PCB), or formed on one substrate. Further, the various components of these devices may be a process or thread, running on one or more processors, in one or more computing devices, executing computer program instructions and interacting with other system components for performing the various functionalities described herein. The computer program instructions are stored in a memory which may be implemented in a computing device using a standard memory device, such as, for example, a random access memory (RAM). The computer program instructions may also be stored in other non-transitory computer readable media such as, for example, a CD-ROM, flash drive, or the like. Also, a person of skill in the art should recognize that the functionality of various computing devices may be combined or integrated into a single computing device, or the functionality of a particular computing device may be distributed across one or more other computing devices without departing from the spirit and scope of the exemplary embodiments of the present invention.
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 the present 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/or the present specification, and should not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.

As shown in
In the current embodiment, the display device DD including one side display area SA, which is bent from one side of the flat display area FA, and the display module DM are illustrated as an exemplary. In the current embodiment, a receiver displayed on a background image as the main image IM1 is exemplarily illustrated, and an icon as the sub image IM2 is exemplarily illustrated. The main image IM1 and the sub image IM2 may be combined with each other to provide a single image or information.
The flat display area FA is parallel to a surface/plane that is defined by a first directional axis DR1 and a second directional axis DR2. A normal direction of the flat display area FA is indicated as a third directional axis DR3. The third directional axis DR3 may be a reference axis for distinguishing front and rear surfaces of each of members from each other. The side display area SA that is bent from the flat display area FA (e.g., bent at a 90-degree angle) displays the sub image IM2 in a direction of a fourth directional axis DR4 that crosses the first direction axis DR1, the second directional axis DR2, and the third directional axis DR3 (e.g., between the third directional axis DR3 and the plane defined by the first and second directional axes DR1 and DR2). However, directions that are indicated as the first to fourth directional axes DR1 to DR4 may be a relative concept, and thus may be changed with respect to each other in other embodiments.
Referring to
When the display device DD is cut by a plane that is defined by the first directional axis DR1 and the third directional axis DR3, the side display area SA may include a curved portion corresponding to a quadrant (e.g., curved to 90 degrees). In this case, a surface area of the side display area SA may increase to further expand an application range of the display device DD. The side display area SA may be bent from the flat display area FA, and the inventive concept is not limited to a shape of the side display area SA.
The display device DD may further include a window member on the display module DM. The window member may define a front surface of the display device DD. The window member may provide an input surface/a touch surface/a display surface for user's input. The window member and the display module DM may be coupled to each other by using an optical transparent adhesion member.
The frame FRM is under the display module DM, and is coupled to the display module DM by a first adhesion member AD1. As shown in
The flat surface support portion FST is coupled to correspond to the flat display area FA. An opening OP may be defined in the flat surface support portion FST. A portion of the bracket BRK, or a portion of a component of the display device DD, may correspond to the opening OP.
The side surface support portion SST is coupled to correspond to the side display area SA. The side surface support portion SST and the side display area SA may be coupled or directly coupled to each other using the first adhesion member AD1, or may be indirectly coupled to each other through the flat surface support portion FST and the flat display area FA, which may be coupled to each other by using the first adhesion member AD1.
The frame FRM is coupled to the bracket BRK through the coupling portion CBN. Because the frame FRM is coupled to the display module DM through the first adhesion member AD1, the coupling portion CBN may perform a function for coupling the display module DM to the bracket BRK.
The coupling portion CBN has a structure that is able to be coupled to, and detached from, the bracket BRK.
The frame FRM may be formed of a metal, such as stainless steel. However, the inventive concept is not limited to the material of the frame FRM. For example, the frame FRM may be formed of a synthetic resin. The frame FRM may have elasticity due to structural characteristics, a thickness, or properties of a material.
The bracket BRK is under the frame FRM, and is detachable from the frame FRM through the coupling portion CBN. The bracket BRK has a plurality of through holes TH1 and TH2 at an area overlapping the coupling portion CBN.
The plurality of through holes TH1 and TH2 may include first through holes TH1 and second through holes TH2. The first through holes TH1 may be at an area overlapping the first female screws ITH1 with respect to the third directional axis DR3. The second through holes TH2 may be at an area overlapping the second female screws ITH2 with respect to the third directional axis DR3.
A protrusion ETD of the bracket BRK may correspond to the opening OP of the frame FRM. When the protrusion ETD corresponds to the opening OP, the bracket BRK and the frame FRM may be more firmly/securely coupled to each other.
The first cover BC1 is under the bracket BRK to protect the bracket BRK. The bracket BRK may have third through holes TH3 at an area overlapping the second through holes TH2 on the third directional axis DR3. A battery for driving the display device DD may be between the first cover BC1 and the bracket BRK.
As illustrated in
When the first female screws ITH1 and the first male screws OTH1 are coupled to each other, the frame FRM and the bracket BRK may be coupled to each other. When the second female screws ITH2 and the second male screws OTH2 are coupled to each other, the frame FRM, the bracket BRK, and the first cover BC1 may be coupled to each other.
When the female screws ITH1 and ITH2 and the male screws OTH1 and OTH2 are coupled to each other, the male screws OTH1 and OTH2 may be rotated to separate from the female screws ITH1 and ITH2. Thus, the frame FRM, the bracket BRK, and the first cover BC1 may be separated from each other.
As described above, the frame FRM, the bracket BRK, and the first cover BC1 may be assembled with each other so that the frame FRM, the bracket BRK, and the first cover BC1 are detached from each other using the female screws ITH1 and ITH2 and the male screws OTH1 and OTH2.
The second cover BC2 may be under the first cover BC1, and may be coupled to the first cover BC1 through a second adhesion member AD2. The second cover BC2 may protect the first cover BC1, and may prevent the third through holes TH3 of the first cover BC1 from being seen through the rear surface of the display device DD.
If the display module DM including the flat display area FA and the side display area SA is directly coupled to the bracket BRK by using the adhesion member, it may be difficult to detach the display module DM from the bracket BRK later. Also, it may be difficult to firmly couple the display module DM to the bracket BRK through the adhesion member due to the bent shape of the side display area SA. As illustrated in
