為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。如本領域技術人員將認識到的,可以以各種不同的方式修改所描述的實施例,而不脫離本發明的精神或範圍。 In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present invention.
在附圖中,為了清楚起見,放大了各元件等的厚度。在整個說明書中,相同的附圖標記表示相同的元件。應當理解,當諸如層、膜、區域或基板的元件被稱為在“另一元件上”、或“連接到另一元件”、“重疊於另一元件”時,其可以直接在另一元 件上或與另一元件連接,或者中間元件可以也存在。相反,當元件被稱為“直接在另一元件上”或“直接連接到”另一元件時,不存在中間元件。如本文所使用的,“連接”可以指物理及/或電連接。 In the drawings, the thickness of each element and the like are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being “on”, or “connected to,” or “overlapped with, another element,” it may be directly on another element. Or connected to another element, or intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements. As used herein, "connected" can refer to physical and/or electrical connections.
在附圖中,相同或相似之參考號碼表示相同或相似之元件,且可以具有相同或相似的結構、材質、功能或形成方式,以下段落將不再一一贅述。 In the drawings, the same or similar reference numbers indicate the same or similar elements, and may have the same or similar structures, materials, functions or formation methods, and the following paragraphs will not repeat them one by one.
應當理解,儘管術語“第一”、“第二”、“第三”等在本文中可以用於描述各種元件、部件、區域、層及/或部分,但是這些元件、部件、區域、及/或部分不應受這些術語的限制。這些術語僅用於將一個元件、部件、區域、層或部分與另一個元件、部件、區域、層或部分區分開。因此,下面討論的“第一元件”、“部件”、“區域”、“層”、或“部分”可以被稱為第二元件、部件、區域、層或部分而不脫離本文的教導。 It should be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and/or parts, these elements, components, regions, and/or Or part should not be restricted by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Therefore, the “first element,” “component,” “region,” “layer,” or “portion” discussed below may be referred to as a second element, component, region, layer or portion without departing from the teachings herein.
這裡使用的術語僅僅是為了描述特定實施例的目的,而不是限制性的。如本文所使用的,除非內容清楚地指示,否則單數形式“一”、“一個”和“該”旨在包括複數形式,包括“至少一個”。“或”表示“及/或”。如本文所使用的,術語“及/或”包括一個或多個相關所列項目的任何和所有組合。還應當理解,當在本說明書中使用時,術語“包括”及/或“包括”指定所述特徵、區域、整體、步驟、操作、元件的存在及/或部件,但不排除一個或多個其它特徵、區域整體、步驟、操作、元件、部件 及/或其組合的存在或添加。 The terminology used here is only for the purpose of describing specific embodiments and is not limiting. As used herein, unless the content clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms, including "at least one." "Or" means "and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the related listed items. It should also be understood that when used in this specification, the terms "including" and/or "including" designate the presence of the features, regions, wholes, steps, operations, elements, and/or components, but do not exclude one or more Other features, overall area, steps, operations, elements, parts And/or the presence or addition of a combination thereof.
此外,諸如“下”或“底部”和“上”或“頂部”的相對術語可在本文中用於描述一個元件與另一元件的關係,如圖所示。應當理解,相對術語旨在包括除了圖中所示的方位之外的裝置的不同方位。例如,如果一個附圖中的裝置翻轉,則被描述為在其他元件的“下”側的元件將被定向在其他元件的“上”側。因此,示例性術語“下”可以包括“下”和“上”的取向,取決於附圖的特定取向。類似地,如果一個附圖中的裝置翻轉,則被描述為在其它元件“下方”或“下方”的元件將被定向為在其它元件“上方”。因此,示例性術語“下面”或“下面”可以包括上方和下方的取向。 In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship between one element and another element, as shown in the figure. It should be understood that relative terms are intended to include different orientations of the device other than those shown in the figures. For example, if the device in one figure is turned over, elements described as being on the "lower" side of other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" may include an orientation of "lower" and "upper", depending on the specific orientation of the drawing. Similarly, if the device in one figure is turned over, elements described as "below" or "beneath" other elements will be oriented "above" the other elements. Thus, the exemplary terms "below" or "below" can include an orientation of above and below.
本文使用的“基本上”包括所述值和在本領域普通技術人員確定的特定值的可接受的偏差範圍內的平均值,考慮到所討論的測量和與測量相關的誤差的特定數量(即,測量系統的限制)。例如,“約”可以表示在所述值的一個或多個標準偏差內,或±30%、±20%、±10%、±5%內。 As used herein, "substantially" includes the stated value and the average value within the acceptable deviation range of the specific value determined by a person of ordinary skill in the art, taking into account the measurement in question and the specific amount of error associated with the measurement (ie , Limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%.
除非另有定義,本文使用的所有術語(包括技術和科學術語)具有與本發明所屬領域的普通技術人員通常理解的相同的含義。將進一步理解的是,諸如在通常使用的字典中定義的那些術語應當被解釋為具有與它們在相關技術和本發明的上下文中的含義一致的含義,並且將不被解釋為理想化的或過度正式的意義,除非本文中明確地這樣定義。 Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those 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 meanings consistent with their meanings in the context of related technologies and the present invention, and will not be interpreted as idealized or excessive The formal meaning, unless explicitly defined as such in this article.
本文參考作為理想化實施例的示意圖的截面圖來描述示例性實施例。因此,可以預期到作為例如製造技術及/或公差的結果的圖示的形狀變化。因此,本文所述的實施例不應被解釋為限於如本文所示的區域的特定形狀,而是包括例如由製造導致的形狀偏差。例如,示出或描述為平坦的區域通常可以具有粗糙及/或非線性特徵。此外,所示的銳角可以是圓的。因此,圖中所示的區域本質上是示意性的,並且它們的形狀不是旨在示出區域的精確形狀,並且不是旨在限制權利要求的範圍。 The exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Therefore, a change in the shape of the diagram as a result of, for example, manufacturing technology and/or tolerance can be expected.

頂面130a之間具有間距192。也就是說,在經由上述的平坦化製程之後,可發出預期的光的第一發光二極體120的另一端(如:具有第一電極120a的一端)仍可以藉由具有導電性的封裝體130以及第二接墊112電性連接陣列基板110。

In one embodiment, after the above-mentioned planarization process, the
在一實施例中,封裝體130與介電層140可以相接觸。也就是說,封裝體130與介電層140之間具有界面191。並且,由於形成封裝體130的光固化步驟中,是藉由其所覆蓋的第一發光二極體120所發出的光而不是藉由外界的光。因此,封裝體130基本上可以共形覆蓋於第一發光二極體120,且使界面191與介電頂面140a之間的夾角193小於90°。
In an embodiment, the
請參照圖1H及圖1K,配置第二發光二極體160於介電層140上,且第二發光二極體160基本上不接觸封裝體130的封裝頂面130a。
