DETAILED DESCRIPTION
[0017] The electronic device of the present disclosure is described in detail in the following description. It should be understood that in the following detailed description, for purposes of explanation, numerous specific details and embodiments are set forth in order to provide a thorough understanding of the present disclosure. The elements and configurations described in the following detailed description are set forth in order to clearly describe the present disclosure. The embodiments are used merely for the purpose of illustration. In addition, the drawings of different embodiments may use like and/or corresponding numerals to denote like and/or corresponding elements in order to clearly describe the present disclosure. However, the use of like and/or corresponding numerals in the drawings of different embodiments does not suggest any correlation between different embodiments.
[0018] The present disclosure can be understood by referring to the following detailed description in connection with the accompanying drawings. It should be noted that, in order to allow the reader to easily understand the drawings, several drawings in the present disclosure only depict a portion of the electronic device, and the specific elements in the drawings are not drawn to scale. In addition, the number and size of each element in the drawings are only for illustration, and are not limited the scope of the present disclosure.
[0019] Throughout the present disclosure and the appended claims, certain terms are used to refer to specific elements. Those skilled in the art should understand that electronic device manufacturers may refer to the same element with different names. The present disclosure does not intend to distinguish between elements that have the same function but different names. In the specification and claims, the terms “comprising”, “including”, “having” and the like are open-ended phrases, so they should be interpreted as “including but is not limited to . . . ”. Therefore, when the terms “comprising”, “including” and/or “having” are used in the description of the present disclosure, they specify the corresponding features, regions, steps, operations and/or components, but do not exclude the existence of one or more corresponding features, regions, steps, operations and/or components.
[0020] Directional terms mentioned in the present disclosure, such as “upper”, “lower”, “front”, “rear”, “left”, “right”, etc., are only the directions referring to the drawings. Therefore, the directional terms are used for illustration, not for limiting the present disclosure. In the drawings, each drawing depicts general features of methods, structures, and/or materials used in particular embodiments. However, these drawings should not be interpreted as defining or limiting the scope or property encompassed by these embodiments. For example, for clarity, the relative sizes, thicknesses, and positions of the various layers, regions, and/or structures may be reduced or enlarged.
[0021] When a corresponding component (such as a layer or region) is referred to as “(disposed or located) on another component”, it may be directly (disposed or located) on another component, or there may be other components between them. On the other hand, when a component is referred to as “directly (disposed or located) on another component”, there is no component existing between them. In addition, when a component is referred to as “(disposed or located) on another component”, the two have an upper-lower relationship in a top-view direction, and this component may be above or below another component, and the upper-lower relationship depends on the orientation of the device.
[0022] The terms “about”, “equal to”, “the same as”, “identical to”, “substantially” or “approximately” are generally interpreted as being within 20% of a given value or range, or within 10%, 5%, 3%, 2%, 1% or 0.5% of the given value or range.
[0023] The ordinal numbers used in the specification and claims, such as the terms “first”, “second”, etc., are used to modify an element, which itself does not mean and represent that the element (or elements) has any previous ordinal number, and does not mean the order of a certain element and another element, or the order in the manufacturing method. The use of these ordinal numbers is used to make a component with a certain name can be clearly distinguished from another component with the same name. The same words may not be used in the claims and the specification. Accordingly, the first component in the specification may be the second component in the claims.
[0024] It should be noted that the following embodiments can replace, recombine, and mix features in several different embodiments to complete other embodiments without departing from the spirit of the present disclosure. The features between the various embodiments can be mixed and used arbitrarily as long as they do not violate or conflict the spirit of the present disclosure.
[0025] In the present disclosure, the length and the width of the component can be measured from an optical microscope image, and the thickness of the component can be measured from a cross-sectional image in an electron microscope, but it is not limited thereto. In addition, certain errors may exist between any two values or directions used for comparison. If the first value is equal to the second value, it implies that there may be an 10% error between the first value and the second value; if the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.
[0026] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It should be appreciated that, in each case, the term, which is defined in a commonly used dictionary, should be interpreted as having a meaning that conforms to the relative skills of the present disclosure and the background or the context of the present disclosure, and should not be interpreted in an idealized or overly formal manner unless so defined.
[0027] In accordance with some embodiments of the present disclosure, the provided electronic device includes spacers with a large buffer space for displacement. In detail, for example, spacers (such as the first spacer and the second spacer as follows) are disposed on the two substrates respectively, and these spacers may contact or intersect each other, and these spacers respectively have part that overlaps with the opposite spacer and other parts that do not overlap with the opposite spacers. In addition, the area (or length) of the non-overlapping part (or portion) may be greater than or equal to the area (or length) of the overlapping part (or portion). When the panel is subjected to external force, the above design can reduce the slippage of the spacers due to displacement, which affecting other layers (for example, alignment layer, but it is not limited thereto) on the opposite substrate. For example, when the spacer shifts and slips, and scratches the alignment layer disposed on the opposite substrate, or uneven alignment may occur.
[0028] In accordance with some embodiments of the present disclosure, the electronic device may include a display device, a light-emitting device, a touch device, a sensing device, an antenna device or a tiled device (a tiled device having any of the above functions or a hybrid function), but it is not limited thereto. The electronic device may include a bendable electronic device or a flexible electronic device, but it is not limited thereto. For example, the electronic device may include, liquid-crystal, light-emitting diode (LED), quantum dot (QD), fluorescence, phosphor, other suitable materials or a combination thereof. For example, the light-emitting diode may include organic light-emitting diode (OLED), micro-LED, micro-LED, mini-LED or quantum dot light-emitting diode (QLED, QDLED), but it is not limited thereto. In some embodiments, the electronic device may include a panel and/or a backlight module. The panel includes a liquid-crystal panel, but it is not limited thereto. It should be understood that the liquid-crystal display device will be taken as an example to illustrate the disclosed electronic device, but it is not limited thereto.
