[0055] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for ease of description, only the parts related to the present disclosure are shown in the drawings.

[0056] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and embodiments.

[0057] Unless otherwise specified, the exemplary embodiments / examples shown will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various embodiments / examples can be additionally combined, separated, interchanged, and / or rearranged.

[0058] In the drawings, cross - hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross - hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be performed in an order different from that described. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0059] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there can be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" can refer to a physical connection, an electrical connection, etc., and can have or not have an intermediate component.

[0060] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", and "side (e.g., in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0061] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus are used to account for the inherent deviations of the measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.
