Description

显示装置
技术领域
本文公开的实施方式涉及显示装置，更具体地，涉及一种能够防止由于其驱动期间所产生的热量而翘曲或破损的显示装置，从而增加消费者对显示装置的外观的满意度，并且与传统的显示装置相比，在减小其厚度和其边框的尺寸的同时，增大了画面沉浸水平(screen immersion level)。
背景技术
一般地，已经积极研究了作为平板显示装置的液晶显示装置、等离子体显示装置、场发射显示装置、有机发光显示装置等。然而，近年来，液晶显示装置和有机发光显示装置由于大规模生产技术、驱动装置的简易性和高图像质量的实现的优点而已成为焦点。
图1是示意性地例示一般液晶显示装置的结构的分解立体图。
如图1所示，一般液晶显示装置包括像素按照矩阵形式来布置以输出图像的液晶面板10、用于驱动像素的驱动器15和16，设置在液晶面板10的后表面上以在液晶面板10的整个表面上发光的背光单元、以及固定地收纳液晶面板10和背光单元的面板引导部45。
液晶面板10包括接合在一起以维持均匀单元间隙的滤色器基板和阵列基板、以及形成在滤色器基板与阵列基板之间的单元间隙中的液晶层。
公共电极和像素电极被形成在滤色器基板与阵列基板彼此接合的液晶面板10上。公共电极和像素电极向液晶层施加电场。当施加到像素电极的数据信号的电压被控制在向公共电极施加电压的状态时，液晶层的液晶由于介电各向异性而根据公共电极与像素电极之间的电场旋转，并且光透射过每个像素或被每个像素阻挡，以显示字符或图像。
此外，为了控制施加至每个像素的像素电极的数据信号的电压，在每个像素中单独地设置了诸如薄膜晶体管(TFT)的开关元件。
上偏振板和下偏振板(未例示)被附接至液晶面板10的外部。下偏振板使通过背光单元的光偏振，上偏振板使通过液晶面板10的光偏振。
参照背光单元，更具体地，用于发光的发光二极管(LED)装配部30被设置在导光板42的一侧上，并且反射器41被设置在导光板42的后表面上。
在这种情况下，LED装配部30包括LED阵列31和附接有驱动LED阵列31的LED印刷电路板(PCB)(未例示)的LED壳体32。
从LED阵列31发出的光入射到由透明材料制成的透明导光板42的侧表面上，并且设置在导光板42的后表面上的反射器41引导光通过导光板42的背面朝向导光板42的上表面上的光学片43透射，以减少光的损失并提高光的均匀性。
在按照上述配置的背光单元的上侧上，由滤色器基板和阵列基板构成的液晶面板10经由面板引导部45来安置。液晶面板10和面板引导部45通过盖底50和壳顶60来联接至背光单元以构成液晶显示装置。
然而，显示装置可能存在的问题在于：由于由金属、塑料树脂等形成的盖底而增大了显示装置的厚度和其边框的尺寸，使得消费者不满意显示装置的外观，并且还劣化了画面沉浸水平。
此外，显示装置可能存在的问题在于：由于背光单元等所产生的热量而使整个显示装置翘曲或破损。
特别地，当显示面板的前表面翘曲以变成凸状时，显示面板的相对端可能落在人的视角之外。因此，显示装置可能存在的问题在于：消费者不满意显示装置的外观，从而可销售性劣化了。画面沉浸水平也劣化了。
因此，越来越需要开发能够防止由于在其驱动期间所产生的热量而使其翘曲或破损的显示装置，从而增加消费者对显示装置的外观的满意度，并且在减小其厚度和其边框的尺寸的同时增大画面沉浸水平。
发明内容
因此，本公开的实施方式致力于基本上消除了由于现有技术的限制和缺点而引起的一个或多个问题的显示装置。
在这种背景下，实施方式的目的在于提供一种显示装置，与由金属或塑料树脂制成的现有技术的盖底相比，该显示装置能够减小其厚度和其边框的尺寸，从而增加消费者对显示装置的外观的满意度，增加显示装置的可销售性，并且增加画面沉浸水平。
实施方式的另一个目的在于提供一种显示装置，该显示装置能够防止由于显示装置中的背光单元等所产生的热量而引起的热膨胀而使其自身翘曲或破损。
附加优点和特征在下面的描述中部分地阐述，并且根据描述将部分地显而易见，或者可以通过本文提供的构思的实践来习得。可以通过在所撰写的说明书、由其可获得的、其权利要求书以及附图中具体指出的结构来实现并获得构思的其它特征和方面。
为了实现发明构思的这些和其它方面，如具体实现和广泛描述的，显示装置包括：显示面板；导光板，所述导光板位于所述显示面板的后侧上；反射器，所述反射器位于所述导光板的后表面上；盖底，所述盖底位于所述反射器的后表面上，其中，所述盖底由玻璃材料制成；以及发光二极管(LED)壳体，所述LED壳体包括位于所述LED壳体的一端上以向所述导光板的端部提供光的LED，所述LED壳体的另一端联接至所述盖底的端部的后表面。
应当理解，前述一般描述和以下详细描述二者都是示例性和说明性的，并且旨在提供对所请求保护的本公开的进一步解释。
附图说明
附图被包括进来以提供对本公开的进一步理解，并且被并入本申请中且构成本申请的一部分，附图例示了本公开的实施方式，并与本描述一起用于解释各种原理。在附图中：
图1是示意性地例示一般的液晶显示装置的结构的分解立体图；
图2是示意性地例示根据本文公开的实施方式的示例性显示装置的截面图；
图3和图4是例示图2的显示装置中的盖底和LED壳体的后表面的示例的后视图；以及
图5至图7是各自示意性地例示根据本文公开的实施方式的示例性显示装置的截面图。
具体实施方式
以下，将参照例示性附图来描述实施方式。在用附图标记表示附图的元件时，尽管相同的元件被示出在不同的附图中，但它们将用相同的附图标记来表示。另外，在本公开的以下描述中，当并入本文的已知功能和配置可能会使本公开的主题相当不清楚时，将省略对其的详细描述。
此外，当描述本公开的组件时，本文可以使用诸如第一、第二、A、B、(a)、(b)等的术语。这些术语中的每一个均不用于限定对应组件的本质、顺序或次序，而仅用于将对应组件与其它组件区分开。在描述某个结构元件“连接至”、“联接至”或“接触”另一个结构元件的情况下，应当理解，另一个结构元件可以“连接至”、“联接至”或“接触”结构元件，以及所述某个结构元件直接连接至或直接接触另一个结构元件。
如图2至图7所示，根据示例性实施方式的显示装置包括：设置在显示面板200的后侧上的导光板203、设置在导光板203的后表面上的反射器205、设置在反射器205的后表面上并由玻璃材料制成的盖底230以及LED壳体220，所述LED壳体220的一端安装有配置为向导光板203的一个端部提供的光的几个LED，LED壳体220的另一端联接至盖底230的一个端部的后表面。
首先，参照图2，在根据示例性实施方式的显示装置中，显示面板200、光学片201等被设置在导光板203的前侧，并且反射器205、盖底230等被设置在导光板203的后侧处。在导光板203的一个端部处安装有LED 211、LED印刷电路板(PCB)210等，并且导光元件(未示出)等被设置在LED壳体220的外部，并且利用粘合构件214来联接至LED壳体220。
此外，配置为控制显示面板200的各种控制单元PCB朝向LED壳体220的后侧弯曲并且被安装在LED壳体220的后侧上，并且壳顶207和背盖213在包围LED壳体220的外侧的同时被联接。
盖底230用于支撑显示面板200和各种组件，并补充整个显示装置的结构刚性。在实施方式中，盖底230可以由薄玻璃材料制成。
因此，与由金属、塑料树脂等制成的现有技术的盖底相比，可以减小厚度，可以大大降低翘曲和膨胀，并且由于玻璃本身的设计优点而可以提高对消费者的可销售性。
这里，为了便于描述，参照显示面板是液晶显示面板的示例来描述示例性实施方式。然而，无论显示面板(例如)是液晶显示面板还是有机发光显示面板，都可以同样地应用这些实施方式。
例如，有机发光显示面板可以包括下基板和接合至下基板以与下基板相对的上基板，下基板包括有在由选通线、数据线和电源(VDD)线限定的每个区域中形成的多个发光单元。
形成在下基板上的多个发光单元中的每一个均可以包括：连接至选通线和数据线的至少一个开关晶体管、连接至开关晶体管和电源(VDD)线的至少一个驱动晶体管、以及通过根据驱动晶体管的开关来控制的电流而发光的有机发光元件(例如，OLED)。上基板可以包括吸湿剂等以保护发光元件免受空气中的湿气或氧气的影响。
在这种情况下，上基板还可以包括连接至驱动晶体管的有机发光元件。在这种情况下，可以省略下基板的发光元件。
在显示面板200是有机发光显示器的情况下，由于自身发光的有机发光显示器的结构而没有配置向面板发光的背光单元。在这种情况下，由于设置在显示面板的后侧的印刷电路板所产生的热量而引起热膨胀。
在显示面板200是液晶显示面板的情况下，显示面板可以包括配置为将背光单元、驱动电路单元、液晶显示面板、背光单元等装配到一个模块中的外壳构件，并且驱动电路单元可以包括诸如数据驱动电路(源驱动电路)、选通驱动电路(扫描驱动电路)、定时控制器和印刷电路板的控制单元。
而且，在液晶显示面板的情况下，液晶层可以存在于上基板与下基板之间，其中，上基板可以是与观看画面单元对应的滤色器基板，并且下基板可以是薄膜晶体管基板。
此外，在形成为矩形形状的显示面板200的任一端部，安装有IC的多个柔性电路膜209可以电连接至显示面板200，并且源PCB 209a被设置成平行于显示面板200。
此外，多个柔性电路膜209通过(例如)胶带自动接合(TAB)工艺来附接至焊盘部分和PCB 209a，并且可以由带载封装(TCP)或柔性板上芯片或膜上芯片(COF)来形成。
因此，显示面板200可以通过多个柔性电路膜209和源PCB 209a来电连结或连接至源PCB 209a，源PCB 209a由壳顶207包围并保护，并且背盖213可以电连接至多个柔性电路膜209以向配置为在显示面板200上显示图像的定时控制器提供各种信号。
在液晶显示面板的情况下，背光单元可以包括LED 211、导光板203等以向显示面板200提供光，并且可以根据LED 211的安装位置而被实现为直下型、边缘型等。
另外，安装有几个LED 211和LED PCB 210的LED壳体220通过粘合构件212来联接至盖底230的后表面，使得由玻璃材料制成的盖底230的端部不翘曲或破损以致散开。
可以使用诸如在其相对侧上设置有粘合层的焊盘、双面胶带、树脂或其它粘合剂的任何粘合材料作为粘合构件212。
此外，LED壳体220可以在从盖底230的一端到盖底230的另一端的纵向方向上被分成两个或更多个部分，使得即使LED壳体220热膨胀，也能够抑制盖底230翘曲或破损。
LED壳体220可以由金属材料形成。考虑到显示装置的外观以及预定的强度水平，LED壳体220可以由铝、铝合金、不锈钢、镀锌钢板等形成。
LED壳体220可以由于从LED 211和LED PCB 210产生的热量而在从一端到另一端的纵向方向上膨胀。因为在纵向方向上分割了LED壳体220，所以膨胀力减小，并且在分割部分之间的间隔中消除了膨胀方向，使得减小了LED壳体220的总膨胀量。
LED壳体220的热膨胀可以成为由玻璃材料形成的盖底230的弯曲和破损的重要因素。因为玻璃材料的膨胀量可能极其小，所以可以通过具有相对较大的热膨胀系数的LED壳体220来向盖底230施加弯曲力。
因此，因为在纵向方向上分割了LED壳体220，并且减小了每个LED壳体分割部分的膨胀量，以减小施加至盖底230的弯曲力，所以可以防止盖底230由于弯曲而破损。
如图3中的示例所示，可以在盖底230的纵向方向的中心处分割LED壳体220。通过在中心处进行分割，LED壳体220的膨胀在相对于中心的分割部分中自行消除，并且中心两侧上的膨胀量变得彼此相等，使得可以在整个区域中均匀地维持由于LED壳体220的热膨胀而导致的盖底230的变形。
如图4中的示例所示，LED壳体220还可以在相对于盖底230的纵向中心的相对侧处被分成相等的长度。当盖底230在相对于中心的相对侧处被分成相等的长度时，每个LED壳体分离部分220的纵向膨胀量变得恒定，并且与LED壳体220被分成两个LED壳体部分的情况相比，可以进一步减小膨胀量。
也就是说，当热量均匀地传递至LED壳体220的整个区域时，LED壳体220的热膨胀偏转(deflection)是均匀的。然而，当热量传递至局部区域时，局部地产生LED壳体220的热膨胀偏转。
因此，即使当盖底230的相对端部和中心部分产生均匀的应力，从而引起LED壳体220的局部热膨胀应力时，盖底230中也不会局部地发生由于较大的变形力而导致的局部破损。
该效果可以通过测试结果来确认。作为在55英寸类型的显示装置上进行的测试的结果，当集成LED壳体220中的温度为70℃时，一端的纵向膨胀量达到0.65mm。然而，当LED壳体220相对于中心分成两个LED壳体部分时，在相同的温度和尺寸条件下，纵向膨胀量减小到约0.33mm，即约50％或更多。
参照盖底230，在相同的温度和尺寸条件下的测试中，纵向方向上的膨胀量仅为0.09mm。因此，在LED壳体220是集成LED壳体的情况下，(壳体220与盖底230之间的)膨胀差为0.56mm。此外，在LED壳体220分成两个LED壳体部分的情况下，(壳体220与盖底230之间的)膨胀差为0.24mm，使得膨胀量的差异减小了约50％或更多。
当LED壳体220与盖底230之间的膨胀量的差异减小时，施加至盖底230的变形力也减小，从而防止盖底230的变形和破损。
热膨胀力或热膨胀量的相对大小由图3和图4中的箭头的大小来指示。如图3和图4所示，与LED壳体220是集成LED壳体的情况相比，在LED壳体220在相对于中心的相对侧处被分成两个或更多个LED壳体部分的情况下，热膨胀力或热膨胀量的大小显著减小。
另外，可以设置中间机壳(cabinet)240，其中，显示面板200位于中间机壳240的前表面上。中间机壳240被设置在导光板203的一端侧表面和盖底230上。
中间机壳240可以维持从显示面板200到盖底230的联接和刚性，可以保护由玻璃材料制成的盖底230，并且可以防止水或异物从外部渗透到内部。
参照图5至图7，中间机壳240通过粘合构件215来联接至显示面板200的后表面，使得可以防止显示面板200偏离预定位置，并且可以使边框的尺寸最小化。
考虑到成型性和材料成本，中间机壳240可以由橡胶、诸如聚氨酯或塑料的合成树脂或金属材料形成。然而，考虑到显示装置的外观以及预定的强度水平，中间机壳240可以由铝、铝合金、不锈钢，镀锌钢板等制成。
此外，参照图7，阻尼构件245可以被设置在显示面板200的端部、粘合构件215和中间机壳240的前表面之间，以吸收冲击。
因为设置了阻尼构件245，所以即使从外部施加冲击，也可以防止显示面板200的端部破损以及来自外部的湿气和异物的渗透。
作为阻尼构件245，可以使用双面胶带、其相对侧中的每一侧上设置有粘合层的泡沫垫、聚氨酯或橡胶等。
此外，彼此面对的中间机壳240的内表面和导光板203的端部可以被设置在彼此间隔开的位置处，并且阻尼构件243可以被设置在它们之间。
导光板203可以由诸如作为透光材料的甲基丙烯酸酯-苯乙烯(MS)的聚合物树脂来形成，使得光可以经由其透射。因此，中间机壳240的内表面和导光板203的端部被设置成彼此间隔开，以防止由于热膨胀而与中间机壳240接触所引起的弯曲、变形、破损等。
而且，即使热膨胀量等于或大于预定水平，阻尼构件243也可以弹性地变形，以吸收导光板203的纵向膨胀量，从而防止导光板203弯曲、变形、破损等。
另外，如图5至图7所示，安置有盖底230的端部的安置槽241可以被设置在中间机壳240的后表面和侧表面上。
当盖底230的端部被嵌入到中间机壳240中并且被安置在安置槽241中时，可以减小从显示面板200到盖底230的厚度，可以保护由玻璃材料制成的盖底230，并且可以使边框的尺寸最小化。
此外，遮光粘合构件217可以被设置在中间壳240的安置槽241与盖底230的端部之间，以防止光泄漏到外部，使得可以防止被导向显示面板200的端部的光从盖底230与中间机壳240之间的间隙泄漏出来的所谓的光泄漏现象。
这里，例如，遮光粘合构件217可以通过印刷例如添加有黑色颜料并且接合至其的材料或通过接合有粘性黑色胶带来被接合在中间机壳240的安置槽241与盖底230的端部之间。遮光粘合构件217阻挡从显示面板200的端部发出的光，从而防止光泄漏现象并且使得从外部看不见内部结构。
如上所述，根据示例性实施方式，与由金属或塑料树脂制成的传统盖底相比，可以减小显示装置的厚度和显示装置的边框的尺寸，从而增加消费者对显示装置的外观的满意度，从而增大显示装置的可销售性，并且还提高了画面沉浸水平。
此外，根据示例性实施方式，可以防止显示装置由于显示装置中的背光单元等中所产生的热量而引起的热膨胀而翘曲或破损。
即使本公开的示例性实施方式的所有组件可以联接为单个单元或联接以作为单个单元来操作，但是本公开不限于这种示例性实施方式。也就是说，在不脱离本公开的范围的情况下，可以选择性地连结和操作所有结构元件中的至少两个元件。
对于本领域技术人员而言，将显而易见的是，在不脱离本公开的技术构思或范围的情况下，可以对本公开进行各种修改和变型。因此，本公开的实施方式旨在覆盖本公开的修改和变型，只要它们落入所附权利要求及其等同物的范围内即可。
