Description

背光模组以及液晶显示器
技术领域
本发明涉及液晶显示器技术领域,尤其涉及一种背光模组以及包含该背光模组的液晶显示器。
背景技术
液晶显示器,或称LCD(Liquid Crystal Display),为平面超薄的显示设备,它由一定数量的彩色或黑白像素组成,放置于光源或者反射板前方。液晶显示器功耗很低,并且具有高画质、体积小、重量轻的特点,因此倍受大家青睐,成为显示器的主流。
液晶显示器包括液晶显示屏及背光模组,液晶显示屏与背光模组相对设置,由背光模组提供显示光源给液晶显示屏,以使液晶显示屏显示影像。液晶显示屏主要是由两片透明基板以及被封于基板之间的液晶构成。目前液晶显示器是以薄膜晶体管(Thin Film Transistor,TFT)液晶显示屏为主,而背光模组按照光源的位置主要分为直下式和侧入式两种方式。图1是现有的一种背光模组及液晶显示器的结构示意图,如图1所示,该背光模组主要包括依次叠层设置的背板、反射片、导光板以及光学膜片组,背光源设置于导光板的侧面。背光源发出光线,经由导光板、光学膜片组将光线改变方向及尽可能的均匀化,在光学膜片组的上方传导发出,提供给液晶显示屏。
如图1所示的背光模组,采用了导光板以及相应较大面积的光学膜片,导光板和光学膜片的价格高昂,并且其材料容易出现损伤及涨缩变形等缺陷,从而造成液晶模组的显示不良;另外,光线在导光板和光学膜片组中传输时,会发生衰减,从而降低了液晶显示器对光的利用效率,因此,在达到提供背光效果的前提下,应当考虑尽量减少光线在导光板和光学膜片组中传输的光程。

有益效果:
本发明提供的背光模组不使用导光板,甚至在一些实施例中还可以不使用光学膜片组,降低了产品的成本;并且在达到提供背光效果的前提下,减少了光线在导光板和光学膜片组中传输的光程,达到提高光源的利用率的效果,提升了产品的质量;另外,该背光模组减少了如前所述的结构部件,可以到达减小整个液晶模组的厚度的效果。

具体实施方式
如前所述,本发明针对现有技术存在的缺陷,提供了一种光学模组,包括:一背板;一反射片,位于所述背板上;一玻璃基板,位于所述反射片上;所述玻璃基板朝向所述反射片的一面设置有一光学网点结构层,所述玻璃基板的另一面为出光面;一背光源,设置于所述玻璃基板的一侧面;其中所述背光源与所述玻璃基板之间还设置有第一偏光片,背光源发出的光经过所述第一偏光片后形成偏振光进入所述玻璃基板,由所述光学网点结构层反射后从所述出光面传导出去。
本发明的还提供了包含如上所述背光模组的液晶显示器,该液晶显示器包括液晶显示屏以及背光模组,其中所述液晶显示屏至少包括依次叠层设置的TFT(Thin Film Transistor,薄膜晶体管)玻璃基板、液晶层、CF(Color Filter,彩色滤光片)玻璃基板以及第二偏光片,其中,背光模组中的玻璃基板和液晶显示屏中的TFT玻璃基板是一体的,即,在同一玻璃基板的一面上设置有背光模组需要的光学网点,在另一面(出光面)上设置有TFT阵列。
如上所述的背光模组以及液晶显示器,背光模组不使用导光板,甚至在一些实施例中还可以不使用光学膜片组,降低了产品的成本;并且在达到提供背光效果的前提下,减少了光线在导光板和光学膜片组中传输的光程,达到提高光源的利用率的效果,提升了产品的质量;另外,该背光模组减少了如前所述的结构部件,可以到达减小整个液晶模组的厚度的效果。
为了更好地阐述本发明的技术特点和结构,以下结合实施例及其附图进行详细描述。
实施例1
图2为本实施例提供的背光模组以及液晶显示器的结构示意图。如图2所示,该液晶显示器包括液晶显示屏2以及背光模组1,其中所述液晶显示屏2至少包括依次叠层设置的TFT玻璃基板201、液晶层202、CF玻璃基板203以及第二偏光片204;光学模组1包括背板101、位于所述背板101上的反射片102、位于所述反射片102上的玻璃基板103(与液晶显示屏2中的TFT玻璃基板201为同一部件)以及设置于所述玻璃基板103的侧面的背光源105。其中,所述玻璃基板103朝向所述反射片102的一面设置有光学网点结构层104,所述玻璃基板103的另一面为出光面(设置有FTF阵列)。所述背光源105与所述玻璃基板103之间还设置有第一偏光片106,本实施例中,第一偏光片106直接粘贴于所述玻璃基板103的侧面,与玻璃基板103紧密结合。
其中,所述光学网点结构层104是通过印刷工艺或刻蚀工艺形成于所述玻璃基板103。该光学网点为可改变光线传播路径的微细结构,网点个体形状不限,只要满足加工便利即可。网点分布状况可根据产品显示的亮度及均匀性的需要做疏密调整,网点密集的区域亮度较高,网点稀疏的区域亮度略低。
本实施例中,所述背光源105由多个发光二极管组成。
背光源105发出的光经过第一偏光片106后形成偏振光进入所述玻璃基板103,经过所述光学网点结构层104以及反射片102的作用,形成垂直于显示面的均匀面光源,从玻璃基板103出光面传导出去,通过TFT玻璃基板201与CF玻璃基板203之间的液晶层202时,光的极性因为液晶的偏转而发生改变,从而可以再次穿过第二偏光片204,达成显示的功能。
实施例2
图3为本实施例提供的背光模组以及液晶显示器的结构示意图。如图3所示,与实施例1不同之处在于,本实施例中的第一偏光片106由一紧固件107固定于与所述玻璃基板103的侧面具有一距离的位置。该位置只要处于玻璃基板103与背光源105即可。将第一偏光片106设置于距离玻璃基板103侧面有一定距离处是为了便于固定且稳固性较好。该液晶显示器的液晶显示屏2的结构以及背光模组1中的其他结构与实施例1中的相同。
实施例3
图4为本实施例提供的背光模组以及液晶显示器的结构示意图。如图4所示,与实施例2不同之处在于,本实施例中的第一偏光片106与背光源105之间还设置有一光学膜片组108(在另外的实施例中,光学膜片组108也可以是设置在第一偏光片106与玻璃基板103之间)。其中,光学膜片组108可以选自扩散片、棱镜片以及增透膜的一种或多种任意组合。该液晶显示器的液晶显示屏2的结构以及背光模组1中的其他结构与实施例2中的相同。
本实施例通过在第一偏光片106与背光源105之间设置有光学膜片组108,改善了背光源105发出的光的质量,提高了整个背光模组的背光效率。但是,与现有技术中所使用的光学膜片组相比,本实施例中使用的光学膜片组的面积大大较小,降低了产品的成本。
综上所述,本发明提供的背光模组以及液晶显示器,背光模组不使用导光板,甚至在一些实施例中还可以不使用光学膜片组,降低了产品的成本;并且在达到提供背光效果的前提下,减少了光线在导光板和光学膜片组中传输的光程,达到提高光源的利用率的效果,提升了产品的质量;另外,该背光模组减少了如前所述的结构部件,可以到达减小整个液晶模组的厚度的效果。
