在本实施例中，所述第一子光源421可以为能够依序发射红光、绿光及蓝光的三色发光二极管（LED）。或者，所述第一子光源421包括依次设置的红光LED、绿光LED及蓝光LED，通过使得红光LED、绿光LED及蓝光LED依次交替单独发光实现第一子光源421能够依序发生红光、绿光及蓝光。
在本实施例中，当位于所述第一开孔411所对应的所述液晶显示面板10区域中的一个背光依靠所述第一驱动电路板422发出的第一驱动信号依序发射红光、绿光及蓝光，对应位置的液晶根据要显示画面的颜色进行不同程度偏转以控制红色、绿色和蓝色在该像素处的组成比例。位于除所述第一开孔411对应的所述液晶显示面板10区域中的一个像素背光源的白光通过控制三个子像素的液晶的偏转来控制要显示的颜色中红色、绿色、蓝色的组成比例。
在本实施例中，所述第一开孔411所对应的所述液晶显示面板10区域的背光频率与除所述第一开孔411对应的所述液晶显示面板10区域的显示画面不相同。例如，现有常规显示区的中的红色子像素、绿色子像素及蓝色子像素的显示1帧画面，而所述第一开孔411对应的区域中红光LED、绿光LED及蓝光LED依序打开各需要三分之一帧的打开时间才能显示一个画面，因此所述第一开孔411对应的区域的背光刷新频率为正常显示区的三倍。当常规显示区的刷新频率为60HZ时，所述第一开孔411对应的区域对应的刷新频率为180HZ。
本实施例中，所述第一开孔411所对应的所述液晶显示面板10区域的背光频率与除所述第一开孔411对应的所述液晶显示面板10区域的显示画面可以相同。例如，现有常规显示区的中的红色子像素、绿色子像素及蓝色子像素的打开时间各为1帧，本申请将常规显示区中的红色子像素、绿色子像素及蓝色子像素的在1帧的打开时间内刷新三次。而所述第一开孔411对应的区域中红光LED、绿光LED及蓝光LED依序打开各需要三之一帧的打开时间才能显示一个画面，因此所述第一开孔411对应的区域的刷新频率与正常显示区的相同。例如，当常规显示区的刷新频率为180HZ时，所述第一开孔411对应的区域对应的刷新频率为180HZ。
本申请通过输出不同帧率或相同帧率的刷新频率进行显示面板，使得所述第一开孔411对应的所述液晶显示面板10区域的显示画面一直，连续的彩色图像帧组成连续的彩色图像，由于人眼的视觉暂留特性，人眼看到的是有蓝、绿、红三基色组成的完整流畅的彩色图像，图像清晰明亮，所述第一开孔411区对应的所述液晶显示面板10无需彩膜层，提高了显示面板的显示效果。
在本实施例中，所述背光模组本体41为迷你LED（mini-LED）直下式背光模组，包括直下式背光源及设于直下式背光源上方的扩散片（未图示），扩散片上设有第一开孔411，第一光源部件42设于扩散片上，该背光模组本体41也可以是常用的侧入式背光模组，包括导光板及设于导光板一侧的侧入式背光源（未图示），导光板上设有第一开孔411，第一光源部件42设于导光板上。
请参阅图1及图2，在本申请的第一实施例中，所述第一光源部件42位于背光模组本体41靠近液晶显示面板10的一侧且围绕于第一开孔411的外侧。
请参阅图1至图3，所述第一开孔411为圆孔。请参阅图3，任一第一子光源421的出光面中心点射出的光线与第一开孔411的中心线相交。为了保证显示时液晶显示面板10对应第一开孔411的区域的亮度均匀，在本申请的第一实施例中，任一第一子光源421的出光方向与垂直于液晶显示面板10所在平面的方向间的夹角也即任一第一子光源421相对于垂直于液晶显示面板10所在平面的方向的倾斜角满足：
a≤arctan[(l+r)/h]。其中，a为第一子光源421的出光方向与垂直于液晶显示面板10所在平面的方向间的夹角，l为第一子光源421的中心与背光模组本体41围成第一开孔411的侧壁之间的距离，r为第一开孔411的半径，h为第一子光源421的中心与液晶显示面板10之间的距离。
请参阅图1，所述显示装置还包括设于所述液晶显示面板两侧的上偏光片20及下偏光片30、设于上偏光片20远离液晶显示面板10一侧的盖板50、位于盖板50与上偏光片20之间的光学胶60以及设于下偏光片30远离液晶显示面板10一侧且与第一开孔411对应的摄像头70，摄像头70可以位于背光模组40远离液晶显示面板10一侧，或者也可以全部或部分容置在背光模组本体41的第一开孔411内。
在本实施例中，所述下偏光片30还设有与所述第一开孔411对应的第三开孔301，所述上偏光片20设有与所述第一开孔411对应的第四开孔201。
在本实施例中，所述液晶层13中的液晶分子可以分区设置。所述第一开孔411对应的液晶层13可以为散射液晶，除所述第一开孔411对应的液晶层13可以为常规液晶。所述散射液晶一般包括多个液晶分子和聚合物，可实现透明态和画面显示态的切换。
在本实施例中，在液晶与聚合物具有相同的各向异性的介电常数，不加电压或电压低于阈值电压时，液晶分子呈水平排列，与其内聚合物材料不存在折射率差，因此不发生散射。当施加的电压高于阈值电压时，液晶分子发生旋转，其方向沿着垂直方向排列，改变了液晶的介电常数的各向异性的特性，因此在液晶和聚合物的表面产生折射率差，光线在此处发生散射，被观察者看到。
在本实施例中，所述液晶层13可以整层设置。所述液晶层13的材料可以为相位液晶。本申请可以对不同区域的相位施加不同的电压控制，可以实现所述第一开孔411对应的区域显示画面。
或者，所述第一开孔411对应的所述下偏光片30及所述上偏光片20保留，即去除所述第三开孔301及所述第四开孔201。此类实施例中的液晶层13材料可以选择为常规液晶。
本申请中液晶层的材料不限定于上述几种。
在本实施例中，在除所述第一开孔411所对应的所述液晶显示面板区域，所述上偏光片20的偏光轴与下偏光片30的偏光轴垂直。
请参阅图5及图6，本申请的第二实施例的液晶显示装置与上述第一实施例的区别在于，所述第一光源部件42位于背光模组本体41围成第一开孔411的侧壁上。
请参阅图5及图6，所述第一开孔411为圆孔。任一第一子光源421的出光面中心点射出的光线与第一开孔411的中心线相交。为了保证显示时液晶显示面板10对应第一开孔411的区域的亮度均匀，在本申请的第二实施例中，任一第一子光源421的出光方向与垂直于液晶显示面板10所在平面的方向间的夹角也即任一第一子光源421相对于垂直于液晶显示面板10所在平面的方向的倾斜角满足：
a’≤arctan(l’/h’)。其中，a’为第一子光源421的出光方向与垂直于液晶显示面板10所在平面的方向间的夹角，l’为第一子光源421的中心与第一开孔411的中心线之间的距离，h’为第一子光源421的中心与液晶显示面板10之间的距离，其余均与第一实施例相同。
在本申请的第二实施例中，采用芯片级封装（CSP）等封装方式将第一光源部件42设置在背光模组本体41围成第一开孔411的侧壁上，需要注意的是，本申请的第二实施例在具体制作时，通过封装方法控制第一光源部件42的任一第一子光源421的出光面朝向液晶显示面板10对应第一开孔411的区域，并且在整体的模组设计时，包覆在背光模组40外侧的边框需要与背光模组本体41围成第一开孔411的侧壁之间预留一定的间距，例如大于0.2mm，以放置第一光源部件42的多个第一子光源421。
需要说明的是，所述液晶显示装置处于摄像模式时，外界光线可以直接经过所述第一开孔411对应的区域射入摄像头70中，实现摄像头70对光线的捕捉。另外，本申请将用于驱动对应第一开孔411的多个第一像素电极1131的多个第一薄膜晶体管1121设置在第一衬底111的框胶区1113，且一个第一薄膜晶体管1121至少与一个第一像素电极1131对应电性连接，也即阵列基板11上对应第一开孔411的区域并不设置薄膜晶体管，从而提升了液晶显示面板10对应第一开孔411区域的开口率及光透过率，提高需要利用摄像头70进行拍摄时摄像头70的进光量，提升成像质量。
在所述液晶显示装置正常显示的状态下，虽然彩色滤光层121对应第一开孔411设有第二开孔1211，但本申请利用第一光源部件42向液晶显示面板10对应第一开孔411的区域依序发射红光、绿光及蓝光，并且采用场色序法（FSC）技术，通过时间分隔的方式，使得液晶显示面板10中分别与多个第一像素电极1131对应的多个像素能够分时显示红色、绿色及蓝色而进行叠加，最终显示特定的颜色，使得液晶显示装置中摄像头70对应的区域也能够实现彩色显示，提升产品的品质。
本申请提供一种液晶显示装置，包括液晶显示面板和背光模组。所述背光模组包括背光模组本体及第一光源部件、第二光源部件。所述背光模组本体设有第一开孔。所述第一光源部件设于背光模组本体上且与第一开孔相对应。当所述液晶显示面板进行显示时，所述第一光源朝向所述液晶显示面板对应所述第一开孔的区域依序发射红光、绿光及蓝光，所述第二光源朝向所述液晶显示面板对应的除所述第一开孔的区域发光，使得液晶显示装置中对应摄像头的区域能够实现正常的彩色显示，产品品质较高。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
