应当理解,尽管本文中可以使用术语“第一”、“第二”等来描述各种组件,但是这些组件不应受这些术语的限制。这些术语仅用于区分一个组件与另一组件。例如,第一组件可以被称为第二组件,并且类似地,第二组件可以被称为第一组件,而不脱离本公开的范围。本文所使用的术语“和/或”包括一个或多个相关所列项目的任何和所有组合。
在下面的描述中,术语“前端”、“后端”、“上部”、“下部”、“上端”和“下端”是基于附图定义的,并非旨在限制各个组件的形状和位置。
在下文中,将参照附图详细描述根据本公开的实施例的显示装置。
参考图1,显示装置1是用于显示图像信息的装置,并且可以包括用作计算机输出设备的电视或监视器,其远程地接收无线电波以显示图像。
显示装置1可以是如实施例中所示的具有平面屏幕的平面显示装置,或者是屏幕是弯曲的曲面显示装置,或者是屏幕可以从平面的变为曲面的、从曲面的变为平面的、或屏幕的曲率可变的可弯折显示装置。
显示装置1可以以直立配置安装在室内或室外的地板或家具上,或者可以以壁挂配置安装在墙壁上或墙壁中。
参照图2和图3,显示装置1包括用于显示图像的显示面板10、用于向显示面板10供给光的背光源20、以及用于支撑显示面板10和背光源20的机架部件30。
显示面板10使用液晶来显示图像,所述液晶的光学性质根据电压和温度的变化而变化。显示面板10具有大致矩形平板的形状,并且包括在前后方向上彼此间隔开的一对玻璃基板11和12,以及设置在这对玻璃基板11和12之间的液晶13。
背光源20设置在显示面板10的后面,以向显示面板10供应光。
背光源20包括用于产生光的光源22、形成为矩形平板形状并设置在显示面板10的背面的导光板21、以及设置在显示面板10的后表面与导光板21之间的前表面以改善光的性质的多个光学片24。
导光板21由透明材料制成,例如聚甲基丙烯酸甲酯(PMMA)。可以在导光板20的前表面上形成各种图案以改变光路。
光源22包括垂直延伸以对应于导光板21的对侧端部的两个印刷电路板22a以及垂直设置在两个印刷电路板22a上的多个发光二极管22b。
印刷电路板22a通常弯折成字母“L”的形式。印刷电路板22a的与导光板21平行的背面部分支撑在导光板21的后表面上。发光二极管22b安装在印刷电路板22a的前表面的面向导光板21的侧表面的侧表面上。
发光二极管22b可以是产生蓝光的蓝色发光二极管。发光二极管22b设置为面向导光板21的相对侧。因此,从发光二极管22b产生的光通过导光板21变为表面光并被供应给显示面板10。
尽管在该实施例中示出的发光二极管22b被设置为面向导光板21的相对侧(左侧和右侧),但这仅是示例。例如,发光二极管22b可以布置为面向导光板21的上侧表面和下侧表面。而且,发光二极管22b可以设置为仅面向导光板的上侧、下侧、左侧和右侧中的一个,或者设置为面向导光板21的所有四个侧面。
光学片24包括设置在导光板21的前表面上的第一二向色片24a、设置在第一二向色片24a的前表面上的量子点片24b、设置在量子点片24b的前表面上的棱镜片24c、以及对光进行漫射的漫射片24d。
第一二向色片24a形成为片状,并根据光的波长选择性地通过或反射光。第一二向色片24a使蓝光通过并反射其他颜色的光。
量子点片24b通过改变光的波长来改善颜色再现性。量子点是大小为几纳米的发光半导体晶体,其分布在量子点片24b中。
量子点片中的量子点接收蓝光并根据其大小产生各种波长的光。亦即,可以用量子点产生具有所有可见光颜色的光。
棱镜片24c通过聚光来提高由背光源20供应的光的亮度。
漫射片24d对从漫射片24d的背面透射的光进行漫射,使得由背光源20供应的光具有均匀的光分布。
反射片23包括附接到导光板21的后表面的第二二向色片23a、以及设置在第二二向色片23a的后表面上的白色片23b。第二二向色片23a将从导光板21向后发射的蓝光反射到导光板21,并且白色片23b反射从量子点片24b发射的白光。
在该实施例中,第二二向色片23a和白色片23b用于反射片23,但是实施例不限于此。例如,反射镜片可以用于反射片。
机架部件30包括用于支撑显示面板10的顶部机架(即,前机架)31、用于支撑导光板21的中间模制件32、用于接纳背光源20的底部机架(即,后机架)33、以及覆盖底部机架33的背面的后盖34。
顶部机架31在显示装置1的前部形成为矩形框架以支撑显示面板10。顶部机架31覆盖中问模制件32和显示面板10的侧表面以用作壳体。
中间模制件32耦接到顶部机架31的后部,并且底部机架33耦接到中间模制件32的后部。中间模制件32支撑导光板21和光学片24的前部的外侧。
底部机架33具有大致矩形板的形状并且耦接到中间模制件32的后部。底部机架33由诸如铝或不锈钢之类的具有良好的导热性以辐射由光源22产生的热的金属材料形成,但底部机架33可以由诸如丙烯腈-丁二烯-苯乙烯(ABS)之类的塑料材料形成。
用于控制显示装置1的各种印刷电路板可以安装在底部机架33的后表面上。后盖34耦接到顶部机架31的背面,以覆盖安装在机架33的后表面上的印刷电路板。
尽管在该实施例中机架部件30包括顶部机架31、中间模制件32、底部机架33和后盖34,但是机架部件30的至少一个组件可以被省略,或者其中的一些组件可以集成在一起。
光学片24依次附接到导光板21的前表面,以形成用于将从光源22产生的光引导到显示面板的导光模块。
具体地,导光模块由导光板21、附接到导光板21的前表面的第一二向色片24a、附接到第一二向色片24a的前表面的量子点片24b、附接到量子点片24b的前表面的棱镜片24c以及附接到棱镜片24c的前表面的漫射片24d形成。
此外,导光模块可以包括反射片23。具体地,第二二向色片23a附接到导光板21的背面,并且白色片23b附接到第二二向色片23a的后部,使得反射片23包括在导光模块中。
一旦通过将光学片24和反射片23集成在导光板21上而形成导光模块,就将导光模块安装在底部机架33上,从而立即完成导光板21、光学片24和反射片23的安装。因此,显示装置1的制造变得较为容易。
为了将从量子点片24b产生的光的漫射角保持在预定角度以下,可以在量子点片24b与棱镜片24c之间形成空气层。
因此,量子点片24b和棱镜片24c通过被施加为彼此间隔开的点的粘合剂25彼此附接,使得在量子点片24b与棱镜片24c之间形成空气层(或气隙)G。换言之,量子点片24b和棱镜片24c通过粘合剂25的彼此间隔开的多个部分而彼此附接,使得量子点片24b和棱镜片24c通过粘合剂25的多个部分间隔开。
参考图4,粘合剂25被施加在量子点片24b的前表面上,但是被限制地施加到非常小的区域,并且施加粘合剂25的区域彼此充分地间隔开。在这种状态下,棱镜片24c附接到量子点片24b的前表面,如图5所示。
当以上述方式将量子点片24b和棱镜片24c附接时,量子点片24b和棱镜片24c通过彼此间隔开的点而彼此附接,但在其他区域中分离以在量子点片24b与棱镜片24c之间形成空气层G。
在图5中,将粘合剂25施加为点的区域被示出为足够大,但这仅用于解释的目的。在实践中,优选地,该区域形成为小于图5中所示的区域。
因此,在形成导光模块的同时,可以通过形成在量子点片24b与棱镜片24c之间的空气层G来减小量子点片24b中产生的白光的漫射角。
尽管光学片24包括第一二向色片24a、量子点片24b、棱镜片24c和漫射片24d,但这仅是示例,并且光学片24的类型可以进行各种改变。
在该实施例中,导光模块安装成与显示面板10分离,但是实施例不限于此。在如图6所示的本公开的另一实施例中,形成导光模块的导光板21、光学片24和反射片23可以附接到显示面板10的后表面以与显示面板10集成。
通过将导光板21、光学片24和反射片23与显示面板集成,显示装置1可以更容易地制造,而且更轻薄。
另外,该实施例的发光二极管包括蓝色发光二极管,并且导光模块包括第一二向色片24a和量子点片24b,但是实施例不限于此。
图7示出了应用于根据本公开的实施例的显示装置的导光模块。
当发光二极管22b是产生白光的白色发光二极管时,导光模块包括导光板21、附接到导光板21的前表面的棱镜片24c、附接到棱镜片24c的前表面的漫射片24d以及附接到导光板21的后表面作为反射片的白色片23′。
在导光模块中,可以在导光板21与棱镜片24c之间形成空气层,以便于入射到导光板21的光发生全反射。
因此,导光板21和棱镜片24c通过被施加为彼此间隔开的点的粘合剂而彼此附接。因此,空气层G可以形成在棱镜片24c与导光板21之间,同时棱镜片24c通过附接到导光板21的前表面而与导光板21集成。
如上所述,由于显示装置包括其中集成有导光板和光学片的导光模块,因此可以容易地制造显示装置。
尽管已经示出和描述了本公开的一些实施例,但是本领域技术人员将理解,在不脱离本公开的原理和精神的情况下,可以在这些实施例中进行改变,本公开的范围由权利要求及其等效形式限定。
