Detailed Description

The following detailed description is provided to assist the reader in obtaining a thorough understanding of the methods, devices, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and/or systems described herein will be apparent to those skilled in the art in view of the disclosure of the present application. For example, the order of operations described herein is merely an example, which is not limited to the order set forth herein, but rather, variations may be made in addition to operations which must occur in a particular order, which will be apparent upon understanding the disclosure of the present application. Moreover, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

The features described herein may be embodied in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and/or systems described herein that will be apparent after understanding the disclosure of the present application.

Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on," "connected to," coupled to, "over," or "overlying" another element, it may be directly "on," "connected to," coupled to, "over," or "overlying" the other element, or one or more other elements may be present therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," directly coupled to, "directly over" or "directly overlying" another element, there may be no intervening elements present.

As used herein, the term "and/or" includes any one of the associated listed items and any combination of any two or more of the items.

Although terms such as "first", "second", and "third" may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited by these terms. Rather, these terms are only 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 referred to in the examples described herein may be termed a second element, component, region, layer or section without departing from the teachings of the examples.

For ease of description, spatial relationship terms such as "above … …," "upper," "below … …," and "lower" may be used herein to describe one element's relationship to another element as illustrated in the figures. Such spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "upper" relative to other elements would then be oriented "below" or "lower" relative to the other elements. Thus, the term "above … …" includes both an orientation of "above … …" and "below … …" depending on the spatial orientation of the device. The device may also be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein should be interpreted accordingly.

The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. The singular forms also are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," and "having" specify the presence of stated features, quantities, operations, elements, components, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and/or combinations thereof.

In other words, the first end 411 of the first case member 41 may be formed with the first portion and the second portion separated from each other, the portions of the first portion and the second portion facing each other may be formed in a stepped shape, and both side portions of the first strip portion 612 of the first moving member 61 may be formed in a stepped shape, so that both side portions of the first strip portion 612 of the first moving member 61 may be respectively fitted with the first portion and the second portion of the first end 411 of the first case member 41, using the structure as described above. For example, the receiving groove as described above may be formed at a predetermined portion of the first portion and/or the second portion of the first end 411 of the first case member 41.

As described above, the first strip portion 612 of the first moving member 61 reciprocates in the first recess during the process of the hinge assembly from the first posture to the second posture and during the process of the hinge assembly from the second posture to the third posture.
