Description

背光模组以及曲面液晶显示装置 技术领域
本发明涉及液晶显示器技术领域，尤其是一种曲面液晶显示装置的背光模组以及曲面液晶显示装置。
背景技术
随着光电与半导体技术的演进，也带动了平板显示器(Flat Panel Display)的蓬勃发展，而在诸多平板显示器中，液晶显示器(Liquid Crystal Display，简称LCD)因具有高空间利用效率、低消耗功率、无辐射以及低电磁干扰等诸多优越特性，已成为市场的主流。
液晶显示器通常包括液晶显示面板(Liquid Crystal Panel)与背光模块(Black Light Module，简称BL)。由于液晶显示面板本身并不具备自发光的特性，因此必须将背光模组配置在液晶显示面板下方，以提供液晶显示面板所需的面光源，如此液晶显示面板可借由背光模组提供的面光源而显示影像。
近年来，各大厂商陆续推出了曲面的液晶显示器，整体而言，曲面的液晶显示器从边缘到边缘都能提供最佳的观看效果，而普通的平面的液晶显示器在屏幕边缘显示效果一直不太理想。曲面液晶显示器整片屏幕朝向用户方向包围的弧形设计，可提供宽阔的全景影像效果，不论是在屏幕中央还是边缘四周，都能够带来同样的视觉享受，并且在近距离观看时还减少了离轴观看的失真度。此外，曲面的液晶显示器会让用户的观赏距离拉长，达到更好的观赏体验。在现有的曲面的液晶显示器中，大多数都采用侧入式的曲面背光模组向曲面液晶显示面板提供显示光源。
随着社会的发展，用户对液晶显示器显示画面的质量要求越来越高，为了提高画面的色彩饱和度，通过改善背光模组中灯条的色度，就可以提升画面的色彩饱和度，现有的技术是在背光模组中增加安装一量子条。量子点(Quantum Dot,QD)技术，是把电子束缚在一定范围内的半导体纳米材料结构技术，有大小在1～100nm范围内的超小化合物晶体构成，在照明与显示领域的应用，是利 用其改变入射光波长的性质，可利用不同大小结晶体控制波长。只要能精确控制结晶体的大小，即可精确控制颜色，且有相当广泛的发色范围。在液晶显示器技术领域，量子点已经被广泛应用，一般是将量子点采用透明玻璃管封装的方式形成量子条。
图1显示了现有技术中常见的量子条的纵向剖视图，图2显示了现有技术中常见的量子条的横向剖视图。参照图1，量子条10在纵向上分为位于中部的发挥作用的有效区11和位于两端的无效区12。参照图2，量子条10通常包括位于内部的功能部分13和包裹着功能部分13的封装部分14，功能部分13通常由构成量子点的材料制成，封装部分14通常由玻璃材料制成。在液晶显示器的背光模组中，量子条通常由固定支架固定安装于背光源与导光板之间。
然而，由于侧入式的曲面背光模组中的导光板弯曲，为此，需要在背光模组中设计出量子条的固定支架，以提升量子条的安装稳定性，提高光源与导光板的耦光效率。

具体实施方式
下面将结合附图以及具体实施例，对本发明实施例中的技术方案进行详细地描述，显然，所描述的实施例仅仅是本发明一部分实例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护范围。
图3为本实施例提供的曲面液晶显示装置的结构示意图。如图3所示，该液晶显示装置包括弧形液晶面板200及背光模组100，所述液晶面板200与所述 背光模组100相对设置并且通过外框300相互固定。所述背光模组100提供显示光源给所述液晶面板200，以使所述液晶面板200显示影像。
其中，参阅图4和图5，背光模组100至少包括背板20、设于背板20上的弧形导光板30以及设于弧形导光板30一侧面的光源40，光源40安装于散热板50上。光源40和弧形导光板30之间设置有量子条10，量子条10安装于量子条固定架60中。进一步地，该背光模组还包括反光板70、中框80和光学膜片组90。反光板70设置于所述背板20与所述弧形导光板30之间，中框80设置于所述量子条固定架60上方，所述光学膜片组90设置于所述弧形导光板30上方，并且至少部分放置于所述中框80上，并且，弧形液晶面板200位于中框80上。其中，所述反光板70与所述弧形导光板30具有相同的弯曲弧形，所述光学膜片组90与所述弧形导光板30具有相同的弯曲弧形。
光源40发出的光通过量子条10后，激发量子条10中的荧光物质，使其发出色域更广的光线，入射到弧形导光板30中。光线从弧形导光板30上方射出，穿过光学膜片组90后入射到弧形液晶面板200。
具体地，所述散热板50包括支撑部51和安装部52，所述支撑部51固定于所述背板20上，所述安装部52用于安装所述光源40，所述支撑部51和安装部52之间的夹角为α。所述量子条固定架60包括连接部61和主体部62，所述连接部61连接于所述支撑部51上，所述主体部62设置于所述光源40和所述弧形导光板30之间。进一步地，所述主体部62设有相互连通的容置槽621、入光槽622和出光槽623，所述容置槽621用于放置量子条10，所述入光槽622朝向所述光源40，所述出光槽623朝向所述弧形导光板30。光线从入光槽622入射到量子条10，再从出光槽623射出。其中，所述主体部62和连接部61之间的夹角为β，并且，夹角α与夹角β相等。根据弧形导光板30入光面法线与背板之间夹角的大小，设定夹角α与夹角β的大小，从而使散热板50的安装部52和量子条固定架60的主体部62近似平行于弧形导光板30的入光面，达到提高光源与导光板的耦光效率。
具体地，本实施例中，如图4和图5所示的，所述量子条固定架60的连接部61上设置有一通孔611，所述散热板50的支撑部51对应设置有的螺纹孔511，所述连接部61通过一螺纹紧固件612连接于所述支撑部51上。
优选的方案中，所述量子条固定架60的材质可以为铝合金。
优选的方案中，所述光源40为LED灯。
综上所述，主要应用于具有弧形液晶面板的曲面液晶显示装置中，该背光模组通过设计散热板中支撑部和安装部的夹角以及量子条固定架中连接部和主体部的夹角，使安装部和主体部近似平行于弧形导光板的入光面，从而使光源发出的光通过量子条后，量子条的出光面与导光板的入光面近于平行，提高了光源与导光板的耦光效率，同时还提升量子条的安装稳定性。
