Description

液晶显示器
技术领域
本发明涉及一种用于液晶显示器(LCD)的设计，其降低了制造成本且同时提供了改善的光学效率。
背景技术
近来，由于液晶显示器(LCD)的小而轻的设计和低功耗，对用于便携装置及监视器和TV中的LCD的需求不断增加。LCD包括液晶显示板、向液晶显示板提供光的背光组件、以及容置液晶显示板和背光组件的底架。背光组件包括各种部件，诸如发光二极管、发光二极管基板、导光板、反射板、光学片、模制框架，模制框架包括侧壁，其围绕发光二极管、发光二极管基板、导光板、反射板和光学片的侧面。因此，LCD的制造成本很高。
为了降低制造成本，可以去除与向液晶显示板提供光不直接相关的模制框架。当去除模制框架时，向导光板的侧面发射的光不易反射回到背光中，使得重新提供到背光组件内的光的比例显著降低，导致减小的光学效率。因此，需要一种用于LCD的设计，其中可以省略模制框架，但光学效率并不降低。
发明内容
因此，本发明的一个方面是提供一种用于液晶显示器(LCD)的设计，其省略了模制框架从而降低了制造成本，但仍具有改善的光学效率。
根据本发明的一个方面，提供一种液晶显示器(LCD)，包括：液晶显示板；导光板，布置在该液晶显示板的背表面上；反射板，包括底板和连接到该底板的多个侧壁，该反射板的底板布置在该导光板的背表面上从而容置该导光板，该反射板的所述多个侧壁从该底板延伸从而围绕该导光板的侧面；及底架，布置在该反射板的背面从而容置该液晶显示板、该导光板、及该反射板。
反射板的所述侧壁的高度可大于或等于该导光板的厚度。液晶显示器还可包括布置在该液晶显示板与该导光板之间的多个光学片，其中该反射板的所述侧壁的高度可大于或等于所述多个光学片和该导光板的组合厚度。
底架可包括：底板，该导光板和该反射板可布置在该底板上；及多个第一侧壁，从该底板延伸从而围绕该反射板的所述侧壁。该底架还可包括：多个台阶差，在平行于该底板的平面上从一些所述第一侧壁延伸至外部；及多个第二侧壁，从所述多个台阶差的一些延伸，所述多个第二侧壁沿向上的方向延伸。该液晶显示板可布置在所述多个台阶差的一些上。
液晶显示器还可包括延伸到所述多个第二侧壁的相应的一些的外部的多个加强单元。所述多个加强单元的每个在所述第二侧壁的一些的上部处弯曲至少一次。
附图说明
结合附图参照下面的详细说明将更好地理解本发明，从而本发明的更彻底的理解及其很多额外的优点将更显而易见，附图中类似的附图标记表示相同或类似的部件。附图中：
图1是分解透视图，示出根据本发明一实施例的液晶显示器(LCD)；
图2是示出图1的反射板的透视图；
图3是示出图1的沿线I-I′取得的LCD的剖面的剖视图；
图4是表格，比较了传统LCD的亮度和根据本发明的LCD的亮度；及
图5是图1的LCD的修改设计，其中加强单元包括在底架中。
具体实施方式
在下面的详细说明中，仅通过示例的方式示出和描述了本发明的仅特定示例实施例。本领域技术人员将理解，所描述的实施例能够以各种不同方式修改而不偏离本发明的精神和范围。因此，附图和说明在本质上看作是说明性的而不是限制性的。这里，将参照附图详细描述本发明。
现在参照附图，图1是分解透视图，示出根据本发明一实施例的液晶显示器(LCD)100，图2是示出图1的LCD 100的反射板120的透视图，图3是示出图1的沿线I-I′取得的LCD 100的剖面的剖视图，图4是数据表格，比较了传统LCD的亮度和根据本发明的LCD 100的亮度。
参照图1至3，根据该实施例的LCD 100包括液晶显示板104、背光组件150、以及底架(或框(bezel))122。液晶显示板104包括第一基板104a、第二基板104b及注入在第一基板104a和第二基板104b之间的液晶(未示出)。液晶显示板104响应于从安装在第二基板104b的一侧上的集成电路106提供的驱动信号而显示图像。
背光组件150包括发光二极管112、发光二极管基板114、导光板118、反射板120、及光学片110。发光二极管112响应于从发光二极管基板114供应的驱动信号而产生具有预定亮度的光。发光二极管基板114响应于从外部提供的控制信号而向发光二极管112提供驱动信号。
导光板118设置在液晶显示板104的背表面上，并向液晶显示板104提供发光二极管112产生的光。导光板118接收来自位于其侧部的发光二极管112的光，并将光提供到布置于其上的液晶显示板104。
反射板120包括底板120a和侧壁120b，底板120a上布置导光板118，侧壁120b从底板120a沿向上的垂直方向延伸从而围绕导光板118的侧面。反射板120在底板120a的顶表面上容置导光板118。
反射板120的侧壁120b的高度大于或等于导光板118的厚度。因此，从导光板118的侧面发射的光可反射回导光板118。在本发明的LCD 100中，侧壁120b包括在反射板120中从而改善光学效率。具体地，由于反射板120比传统模制框架具有更高的反射率，所以即使省略模制框架，也能实现比传统更高的光学效率。因此，可以提供具有改善的亮度的LCD 100。
此外，反射板120的侧壁120b填充导光板118和底架122的侧面之间的空间，从而可获得稳定的光学特性。此外，反射板120的侧壁120b的高度可设定为等于或大于导光板118和光学片110的组合厚度，从而最大化背光组件150的光学效率。通过以此方式设计侧壁120b的高度，反射板120的侧壁120b可以形成为在光学片110叠置到导光板118上时围绕光学片110的侧面。光学片110位于液晶显示板104与导光板118之间且用于改善从导光板118提供的光的亮度以及将所述光传送到液晶显示板104。
底架122由具有高强度的金属制成并位于反射板120下面以容置液晶显示板104和背光组件150。更具体地，底架122包括底板122a、第一侧壁122b、台阶差122c、及第二侧壁122d。光学片110、导光板118和反射板120布置在底板122a上。第一侧壁122b沿向上的垂直方向从底板122a延伸从而围绕反射板120的侧壁120a。然后，台阶差122c从第一侧壁122b沿垂直方向向外延伸并设置在与底板120a平行的平面上，从而液晶显示板104可搁置于其上。另外，第二侧壁122d从台阶差122c延伸并沿向上的垂直方向弯折从而围绕液晶显示板104的侧面。
如上所述，当光学片110、导光板118、及反射板120稳定地容置在由底架122的底板122a和第一侧壁122b生成的内部空间中时，可以省略模制框架。在根据该实施例的上述LCD 100中，省略了模制框架从而降低LCD100的制造成本并为LCD 100提供更轻巧的设计。另外，由于背光组件150插在底架122中且由于底架122由高强度的金属制成，因此所得到的LCD100比现有技术具有甚至更大的强度。此外，在根据本发明实施例的LCD 100中，提供具有围绕导光板118的侧面的侧壁120b的反射板120以改善光学效率。因此，可以改善液晶显示板104显示的图像的亮度。
现在参照图4，图4是实验数据表格，比较了其中包括模制框架且反射板中不设置侧壁的传统LCD的亮度和省略了模制框架且反射板120中设置侧壁120b的根据本发明的LCD 100的亮度。从图4的数据可见，根据本发明的LCD 100的亮度平均比传统LCD大10％。
在图4中，用于测量亮度的LCD为2英寸(即，有源区的水平和垂直尺寸分别为30.6mm和40.8mm)，并且对于每个传统LCD和根据本发明的LCD使用10个模块。在用于测量亮度的LCD中，条件诸如显示板的尺寸和发光二极管设定为相同。
在根据本发明的供选实施例中，为了进一步改善LCD 100的强度，底架122的结构可以变化。例如，图5是剖视图，示出了在图1和3的底架122中包括加强单元124的LCD的剖面。如图5所示，可以进一步提供延伸到底架122的第二侧壁122d的外部的加强单元124。加强单元124在第二侧壁122d的上部处弯曲至少一次，从而改善LCD 100的强度。通过在底架122中包括加强单元124，从外部施加的冲击通过加强单元124释放，从而液晶显示板104可得到更好的保护。
在本发明中，LCD省略了模制框架并在反射板上包括侧壁，提供了更轻巧、更低成本制造并产生更亮图像的设计。然而，本发明不限于此。例如，在本发明的供选实施例中，侧壁形成在插有模制框架的LCD的反射板中以改善光学效率。在该实施例中，底架中可不形成台阶差。
尽管本发明已经结合特定示例实施例进行了描述，但应该理解，本发明不限于所公开的实施例，相反，本发明意图涵盖包括在所附权利要求的精神和范围内的各种修改和等效设置。
