It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the invention, and together with the description serve to explain the inventive concepts.
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the invention. As used herein “embodiments” and “implementations” are interchangeable words that are non-limiting examples of devices or methods employing one or more of the inventive concepts disclosed herein. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments. Further, various exemplary embodiments may be different, but do not have to be exclusive. For example, specific shapes, configurations, and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concepts.
Unless otherwise specified, the illustrated exemplary embodiments are to be understood as providing exemplary features of varying detail of some ways in which the inventive concepts may be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions, and/or aspects, etc. (hereinafter individually or collectively referred to as “elements”), of the various embodiments may be otherwise combined, separated, interchanged, and/or rearranged without departing from the inventive concepts.
The use of cross-hatching and/or shading in the accompanying drawings is generally provided to clarify boundaries between adjacent elements. As such, neither the presence nor the absence of cross-hatching or shading conveys or indicates any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and/or any other characteristic, attribute, property, etc., of the elements, unless specified. Further, in the accompanying drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. When an exemplary 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. Also, like reference numerals denote like elements.
When an element, such as a layer, is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, an element or layer 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. To this end, the term “connected” may refer to physical, electrical, and/or fluid connection, with or without intervening elements. Further, the D1-axis, the D2-axis, and the D3-axis are not limited to three axes of a rectangular coordinate system, such as the x, y, and z-axes, and may be interpreted in a broader sense. For example, the D1-axis, the D2-axis, and the D3-axis may be perpendicular to one another, or may represent different directions that are not perpendicular to one another. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” may be construed as X only, Y only, Z only, or any combination of two or more of X, Y, and Z, such as, for instance, XYZ, XYY, YZ, and ZZ. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms “first,” “second,” etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Thus, a first element discussed below could be termed a second element without departing from the teachings of the disclosure.
Spatially relative terms, such as “beneath,” “below,” “under,” “lower,” “above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), and the like, may be used herein for descriptive purposes, and, thereby, to describe one elements relationship to another element(s) as illustrated in the drawings. Spatially relative terms are intended to encompass different orientations of an apparatus in use, operation, and/or manufacture in addition to the orientation depicted in the drawings. For example, if the apparatus in the drawings 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. Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and, as such, the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. 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. Moreover, the terms “comprises,” “comprising,” “includes,” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It is also noted that, as used herein, the terms “substantially,” “about,” and other similar terms, are used as terms of approximation and not as terms of degree, and, as such, are utilized to account for inherent deviations in measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.
Various exemplary embodiments are described herein with reference to sectional and/or exploded illustrations that are schematic illustrations of idealized exemplary embodiments and/or intermediate structures. 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, exemplary embodiments disclosed herein should not necessarily be construed as limited to the particular illustrated shapes of regions, but are to include deviations in shapes that result from, for instance, manufacturing. In this manner, regions illustrated in the drawings may be schematic in nature and the shapes of these regions may not reflect actual shapes of regions of a device and, as such, are not necessarily intended to be limiting.
Hereinafter, exemplary embodiments of the inventive concepts will be described in detail with reference to the accompanying drawings.

In other embodiments, transmission area TA may have various shapes.
The bezel area BZA may be adjacent to the transmission area TA. The bezel area BZA may have a predetermined color. The bezel area BZA may surround the transmission area TA when viewed in a plan view.

In other embodiments, the bezel area BZA may be adjacent to only one side of the transmission area TA or may be omitted. The electronic apparatus EA according to the embodiment of the inventive concepts may be embodied in many ways and is not limited to a specific embodiment.

The protective panel PF may include at least one of an embossed sheet, a cushion sheet, a heat dissipation sheet, or a light blocking sheet. The embossed sheet may include fine bends to prevent non-uniform bubbles from being formed between the display panel DP and the protective panel PF, and thus improving bondage between the display panel DP and the protective panel PF. The cushion sheet may absorb an external impact to protect the display panel DP and may include sponge, foam, and/or urethane resin. The heat dissipation sheet may easily exhaust or release heat generated from the display panel DP to the outside and may include a metal having high heat conductivity.

In the present embodiment, the second portion RP may protrude from the first portion PP. The second portion RP may not overlap with the display panel DP when viewed in a plan view.
The second portion RP may have a modulus greater than that of the circuit board CB. In more detail, the second portion RP may have a higher modulus than the flexible film FF. Thus, the second portion RP may be less flexible than the flexible film FF. This will be described later in more detail.
In the present embodiment, the first portion PP and the second portion RP may be formed as a single unitary body. For example, the first portion PP and the second portion RP may be formed of the same material and may be connected to each other without a coupling member to constitute a single unitary body shape.

Due to the external impact PS, the second portion RP disposed between the window WM and the protrusion of the circuit board CB may come in contact with the window WM instead of the protrusion of the circuit board CB. Thus, the circuit board CB may be protected from colliding with the window WM.
According to the embodiments of the inventive concepts, the second portion RP may prevent the circuit board CB from being in direct contact with the window WM, and thus it is possible to prevent damage of the circuit board CB by the collision with the window WM. As a result, reliability of the display unit DU may be improved.
As illustrated in
In the present embodiment, the cover panel film CVP may have a rework property. Thus, the cover panel film CVP may protect the display panel DP and/or the protective panel PF and prevent a collision between the circuit board CB and the window WM before being assembled to the electronic apparatus EA and/or during a process of testing and/or moving the display unit DU.
Thereafter, the cover panel film CVP may be removed from the display panel DP immediately before the assembling process, and the protrusion FF_R of the circuit board CB may be bent to overlap with the rear surface of the display panel DP and then may be assembled to the electronic apparatus EA. Since the cover panel film CVP is removed, the circuit board CB may be disposed on an exposed rear surface of the protective panel PF.
According to the embodiments of the inventive concepts, the cover panel film CVP may protect the circuit board CB from damaged by a collision between the circuit board CB and the window WM. Such collision may occur by interference with an external component and/or worker's mishandling of device before the assembling process.
In addition, the cover panel film CVP may protect the display module, and thus it is possible to prevent the rear surface of the display module from being damaged by a contaminant or impact that may occur in the manufacturing process. Furthermore, since the electronic apparatus EA is assembled after removing the cover panel film CVP, interference between the second portion RP and other component(s) may be prevented. This may improve convenience and efficiency in assembling the display unit DU-1.
Meanwhile, according to some embodiments of the inventive concepts, the cover panel film CVP may be easily attachable and detachable, and thus the cover panel film CVP may be easily replaced with a new cover panel film when it is damaged in a process. This may be improve the rework-ability of the display unit DU-1, which may reduce a cost of the process of assembling the electronic apparatus EA using the display unit DU-1 and improve assembly efficiency.
The cover panel film CVP_U may further include an adhesive member ADL disposed on the first portion PP. The adhesive member ADL may be permanently adhesive and/or detachably adhesive. In the present embodiment, the adhesive member ADL is shaded for the purpose of ease and convenience in description and illustration.
The adhesive member ADL may be disposed on one surface of the first portion PP. The adhesive member ADL may couple the first portion PP to the display panel DP (see
The adhesive member ADL may be spaced apart from the second portion RP when viewed in a plan view. The adhesive member ADL may not overlap with the second portion RP when viewed in a plan view. The second portion RP may function as a handle when the cover panel film CVP_U is detached.
According to the embodiments of the inventive concepts, the cover panel film CVP_U may further include the adhesive member ADL, which may improve the rework property of the cover panel film CVP_U and bonding strength with the display panel DP or the protective panel PF.

According to embodiments of the inventive concepts, a position of the second portion RP-B may vary under the condition that the second portion RP-B is disposed between the circuit board CB-B and the window WM.

According to the embodiments of the inventive concepts, it is possible to prevent interference between the circuit board CB and other components (e.g., the receiving member) in the assembling (S30), and thus assemblability of the display unit DU-1 may be improved.
As illustrated in
In some embodiments, the window WM-V may have a shape different from a rectangular shape. In the present embodiment, the display panel DP has a rectangular shape, and the window WM-V has a trapezoid shape of which corners are rounded.
A front surface IS-V of the window WM-V may include a transmission area TA and a bezel area BZA. In the present embodiment, edges of the transmission area TA may not be parallel to side surfaces of the window WM-V. A planar area of the bezel area BZA may be non-uniform along the edges of the transmission area TA.
In the present embodiment, protruding degrees of the side surfaces of the window WM-V from the display panel DP may not be equal to each other. Thus, a protrusion FF_R of the circuit board CB may protrude from the side surface of the window WM-V to the outside or be disposed inside the window WM-V, depending on a position of the circuit board CB and a position of the side surface of the window WM-V.
In some embodiments, the display unit DU-V may further include a cover panel film CVP, such that the protrusion FF_R of the circuit board CB protruding outside the display panel DP does not collide with the side surfaces of the window WM-V. Thus, it is possible to easily prevent a collision between the circuit board CB and the window WM-V provided in various shapes.
In
Each of the display units DU-V1 and DU-V2 may be disposed on an inner side VH-1 of a door part of the electronic apparatus VH. In the present embodiment, the inner side VH-1 of the door part is shaded for the purpose of ease and convenience in description and illustration. Each of the display units DU-V1 and DU-V2 may be inserted in the inner side VH-I of the door part.
An image obtained through a camera module CM of components of the electronic apparatus VH may be displayed on each of the display units DU-V1 and DU-V2 so as to be provided to a user (e.g., a driver). Thus, a component (e.g., a side mirror) disposed outward may be omitted, and information on the rear of the electronic apparatus VH may be easily visible to a user (or a driver) through the display units DU-V1 and DU-V2 disposed on the inner side VH-I of the door part.
In addition, according to the embodiments of the inventive concepts, the shape of the window WM-V may be variously modified or changed, and thus the display units DU-V1 and DU-V2 may be easily assembled to an irregular space (e.g., the inner side VH-I of the door part) without interference. As a result, process reliability of the display units DU-V1 and DU-V2 may be improved.
According to the embodiments of the inventive concepts, a collision between the circuit board and the window may be prevented in the assembly process, thus improving reliability of the display unit assembly process. In addition, assembly line workers may handle the display unit easily, thus simplifying the process. Furthermore, the electronic apparatus may be manufactured using the display unit with improved rework property, and thus reducing the process cost.
Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the inventive concepts are not limited to such embodiments, but rather to the broader scope of the appended claims and various obvious modifications and equivalent arrangements as would be apparent to a person of ordinary skill in the art.
