具体实施方式
在下文中，参照显示本发明构思的各实施例的附图更加充分地描述本发明构思。然而，本发明构思可以许多不同的形式被实施，而且不应该被解释为限于在此列举的各实施例。相反，这些实施例被提供使得本公开将全面和完整，而且将把本发明构思的范围充分传达给本领域的技术人员。在附图中，为清楚起见，各层和各区域的尺寸和相对尺寸可能被扩大。相似的附图标记始终指代相似的元件。
将理解的是，尽管术语第一、第二、第三等在此可被用于描述各种元件、部件、区域、层和/或部分，但是这些元件、部件、区域、层和/或部分不应被这些术语限制。这些术语仅用于将一个元件、部件、区域、层或部分与另外的区域、层或部分区别开。因此，下面讨论的第一元件、部件、区域、层或部分可被称作第二元件、部件、区域、层或部分，而不偏离本发明构思的教导。
为易于描述，诸如“以下”、“之下”、“下部”、“下方”“之上”、“上方”“上部”等的空间相关术语在此可被用于描述如图中例示的一个元件或特征与另外的元件或特征的关系。将被理解的是，空间相关术语旨在涵盖设备在使用或运行时的除了图中所描绘的方位之外的不同方位。例如，如果各图中的设备被翻转，被描述为在另外的元件或特征“之下”或“以下”或“下方”的元件或特征于是将被定向为在另外的元件或特征“之上”。因此，示例性术语“之下”和“下方”可涵盖“之上”和“之下”两种方位。设备可以被以另外的方式定向（旋转90度或在其它方位）并且在此使用的空间相关描述词语可被相应地解释。另外，还将被理解的是，当层被提及为在两个层“之间”时，其可为两个层之间的惟一层，或者也可存在一个或更多的中间层。
在此使用的术语仅用于描述各特定实施例的目的，并不旨在限制本发明构思。如在此使用的单数形式的“一”、“某一”和“所述”旨在也包括复数形式，除非上下文明确另外表示。将被进一步理解的是，术语“包括”和/或“包含”当被用于本说明书中时，其明确说明所述特征、整体、步骤、运行和/或部件的存在，但是不排除一个或更多的其它特征、整体、步骤、运行、元件、部件和/或其集合的存在或增加一个或更多的其它特征、整体、步骤、运行、元件、部件和/或其集合。如在此使用的术语“和/或”包括一个或多个关联的所列项目的任意和所有组合。
将理解的是，当一元件或层被提及为在另一元件或层“上”，“连接到”、“联接到”或“邻近”另一元件或层时，其可以直接在另一元件或层上、直接连接到、联接到或邻近另一元件或层，或者可存在中间元件或层。相反，当一元件被提及为“直接”在另一元件或层“上”，“直接连接到”、“直接联接到”或“紧邻”另一元件或层时，则不存在中间元件或层。
除非另外限定，在此使用的所有术语（包括技术和科学术语）具有与本发明构思所属的领域中的普通技术人员通常理解的含义相同的含义。将被进一步理解的是，诸如在通常使用的词典中定义的那些术语应该被解释为具有与它们在相关领域背景和/或本说明书中的含义一致的含义，而且将不会以理想化或过于表面化的意义被解释，除非在此被这样明确地限定。
图1例示根据实施例的显示设备的透视图。图2例示图1中的显示设备的分解透视图。图3例示沿图1中的线Ⅰ-Ⅰ’截取的剖视图。图4例示图3中区域A的放大视图。
参见图1至图4，根据本发明构思的实施例的显示设备包括显示面板100、用于接纳显示面板100的壳体200、设置在显示面板100上方的窗口构件400和设置在显示面板100与壳体200之间的缓冲板300。
显示面板100显示图像。显示面板100不限于特定情况。例如，显示面板100可包括自发光显示面板，诸如有机发光显示（OLED）面板、等离子体显示面板（PDP）等。而且，显示面板100可包括非发光型显示面板，诸如液晶显示（LCD）面板、电泳显示（EPD）面板、电润湿显示（EWD）面板等。如果非发光型显示面板被用作显示面板100，则显示设备可包括将光向显示面板100供给的背光单元。
壳体200接纳显示面板100。图1例示壳体200的示例实施例，壳体200包括单个构件，该单个构件具有用于在其中接纳显示面板100的空间或腔。然而，壳体200可由两个联接构件（未示出）形成，该两个联接构件一起形成空间或腔。在示例实施例中，将描述由一个构件形成的壳体200。
壳体200可进一步接纳印刷电路板，多个有源元件（未示出）和/或多个无源元件（未示出）被安装在印刷电路板上。壳体200可进一步接纳适用于显示设备的电源供给单元（未示出）。
缓冲板300被设置在显示面板100与壳体200之间，并能够吸收显示面板100承受的外部振动。缓冲板300防止外部振动被直接施加到显示面板100。例如，缓冲板300可减轻外部振动对显示面板100的冲击。
缓冲板300包括能够吸收外部振动的缓冲膜301和在缓冲膜的相反的第一和第二表面的一个或二者上沉积的粘合层302。例如，粘合层302可被沉积在例如缓冲膜301的邻近显示面板100的第一表面上，以将缓冲板300固定到显示面板100。另外或作为选择，粘合层302可被沉积在例如缓冲膜301的邻近壳体200的第二表面上，以将缓冲板300固定到壳体200。缓冲膜301可限定缓冲板300的第一表面300a。粘合层302可限定缓冲板300的相反的第二表面300b。缓冲膜301可包括泡沫或泡沫堆积结构，并可具有大约300μm的厚度。
缓冲板300包括多个气泡排出构件310。气泡排出构件310可包括延伸穿过缓冲板300，例如穿过缓冲膜301和粘合层302的开口，以允许移除在缓冲板300被粘合到显示面板100或壳体200时产生的气泡。例如，气泡可通过气泡排出构件310。气泡排出构件310的每一个可包括第一端310a和第二端310b。第一端310a可在粘合层302中，第二端310b可在缓冲膜301中。气泡排出构件310的每一个可包括通过切割穿过部分缓冲板300形成的缝隙，例如矩形开口。
气泡排出构件310的每一个可以贯穿角α被设置在缓冲板300中，并可相对于缓冲板300的厚度方向倾斜，即相对于缓冲板300的厚度倾斜。根据实施，气泡排出构件310的每一个可相对于缓冲板300的第一表面300a和第二表面300b的平面倾斜。贯穿角α可为气泡排出构件310之一与垂直于缓冲板300的平面并从气泡排出构件310的第一端310a延伸至缓冲板300的第一表面300a的线之间形成的角。气泡排出构件310的每一个的贯穿角α可大于30度。
气泡排出构件310的每一个的贯穿角α满足以下方程式。
tanα≥W/T (1)
在方程式中，W表示缝隙的宽度，并且T表示缓冲板300的厚度。例如，T包括缓冲膜301的厚度和粘合层302的厚度。
根据实施，气泡排出构件310的每一个的第一端310a位于不同于第二端310b，例如不与第二端310b对准的位置。例如，第一端310a与第二端310b可不垂直对准。根据一些实施例，第一端310a与第二端310b不以相对于彼此相互重叠的方式被设置。根据一些实施例，第一端310a和第二端310b可相对于彼此被斜向设置。因此，防止气泡排出构件310被显示设备的使用者看到是可能的。
根据各实施例，窗口构件400被设置在显示设备的一侧上，图像由显示面板100通过窗口构件400输出。窗口构件400被与壳体200联接，以与壳体200一起形成显示设备的外表面。
窗口构件400包括显示区域AR和邻近显示区域AR的至少一部分的非显示区域NAR，显示面板100产生的图像在显示区域AR中被显示。
非显示区域NAR不显示图像。非显示区域NAR的至少一部分可包括输入图标区域NAR-I。当显示设备在特定模式下运行时，输入图标区域NAR-I可被激活。
根据实施例显示设备可进一步包括粘合板500，粘合板500被设置在显示面板100与窗口构件400之间。粘合板500被用于将窗口构件400附接到显示面板100。粘合板500可为透明的，以防止降低自显示面板100的图像输出的亮度。
如上所述，根据实施例显示设备包括气泡排出构件310，气泡排出构件具有贯穿角α并相对于缓冲板300的厚度方向倾斜。因此，气泡排出构件310可不被显示设备的使用者看到。
下面，将参照图5和图6描述另一实施例。在图5和图6中，与图1至图4中例示的元件相同的元件由相同的附图标记来标识，并且其描述被省略。将仅讨论图1至图4所示的实施例与图5和图6所示的实施例之间的差异。
图5例示根据另一实施例的可被用于显示设备的缓冲板的透视图。图6例示沿图5中的线Ⅱ-Ⅱ’截取的剖视图。
参见图5和图6，根据实施例，显示设备的缓冲板300包括气泡排出构件320。气泡排出构件320可为延伸穿过缓冲板300，例如延伸穿过缓冲膜301和粘合层302的圆形通孔。气泡排出构件320的每一个可包括第一端320a和第二端320b。第一端320a可在粘合层302中，第二端320b可在缓冲膜301中。
气泡排出构件320的每一个可以贯穿角β被设置在缓冲板300内，并且可以相对于缓冲板300的厚度方向倾斜，即相对于缓冲板300的厚度倾斜。气泡排出构件320的每一个可相对于第一表面300a和第二表面300b的平面倾斜。贯穿角β可为气泡排出构件320之一与垂直于缓冲板300并从气泡排出构件320的第一端320a延伸至缓冲板300的第一表面300a的线之间形成的角。气泡排出构件320的每一个的贯穿角β理想地可为大于30度。
气泡排出构件320的每一个的贯穿角β满足以下方程式。
tanβ≥D/T (2)
在方程式中，D表示通孔的直径，并且T为缓冲板300的厚度。
如上所述，气泡排出构件320不会被显示设备的使用者看到。
作为概括和回顾，在通常的移动设备的壳体中，当缓冲板被附接到壳体时可产生气泡。由于这个原因，缓冲板具有用于移除气泡的缝隙。然而，该缝隙在移动设备的使用中能被使用者看到。
相比之下，根据各实施例，缓冲板包括形成为贯穿缓冲板并用于防止粘合时气泡的产生的气泡排出构件。气泡排出构件具有相对于缓冲板的厚度方向倾斜的贯穿角。因此，在具有根据各实施例的缓冲板的显示设备中，防止气泡排出构件被使用者看到是可能的。
上面公开的主题被认为是例示性的，并非约束性的，所附的权利要求书旨在覆盖所有这种落入真正的精神和范围内的修改、改进以及其它实施例。因此，在法律允许的最大程度上，本范围将通过下面的权利要求书及它们的等价物的最广泛许可的阐释而被确定，而不应该被前述详细的描述所约束或限制。
