但是在现有技术中，由于液晶显示器液晶并非自发光，必须藉由背光提供光源，但由于液晶分子的配向无法完全符合设计要求等原因，在显示黑画面时，像素无法完全关闭，有一些光线能从面板中发出，造成了对比度较低，无法满足消费者对于高画质的要求。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是现有技术的LED面板结构示意图；
图2是本发明光阀装置关闭状态的放大示意图；
图3是本发明实施例的光阀装置的放大示意图
图4是第一种具有图2所述的光阀装置的显示装置示意图；
图5是本发明的彩膜基板黑矩阵示意图；
图6是第二种具有图2所述的光阀装置的显示装置示意图；
图7是第三种具有图2所述的光阀装置的显示装置示意图；
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。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前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图2，本发明的光阀装置200，包括驱动基板12，驱动基板12上部分区域(透光区122)透光，其他的区域(遮光区121，覆盖有黑矩阵)不透光。所述遮光区121和透光区122间隔设置、交替分布，所述遮光区121用于阻挡光线通过，所述透光区122处的光线可以通过驱动基板12，所述光阀装置200还包括遮光单元(未编号)，所述遮光单元包括驱动单元11、第一遮光板15和两个第二遮光板10，所述驱动单元11与所述第一遮光板15固定在所述驱动基板12的遮光区121，所述第二遮光板10与所述驱动单元11连接，所述第一遮光板15介于两个所述第二遮光板10之间。
每个光阀装置200都对应着一个子像素，当两个相邻的透光区121对应的子像素需要透入背光光线时，所述第二遮光板10位于遮光区121，即此时光阀装置200处于开启状态，背光光线可以从所述透两个光区121直接进入驱动基板12，该像素不显示黑色；请参阅图3，当光阀装置200对应的子像素需要显示黑色时，在驱动单元11的驱动下，两个所述第二遮光板10向所述第一遮光板15并拢，此时所述第二遮光板10正对所述透光区122，以挡住背光光线通过透光区122进入驱动基板12，即此时光阀装置200处于关闭状态，该光阀装置200对应的子像素完全关闭，与周围形成高对比度，提升了显示效果。
进一步的，所述第二遮光板10与所述驱动单元11可以通过摆臂14连接摆臂14可用热致变形器件(如形状记忆合金)、电致变形器件等为主要部件，摆臂14带动第二遮光板10旋转。更进一步的，为了减少光能损失，提高光能利用率，可以在第一遮光板15、两个第二遮光板10和所述摆臂14上涂有高散射涂层，将射向该涂层的光线反射回背光光路，减少了光能损失。
请参阅图4，本实施例还提供一种显示装置100，其包括多个子像素，子像素分为多种不同颜色，且每个子像素中设有一个光阀，其中至少部分光阀为上述的光阀装置200，显示装置100包括从上到下依次设置的上偏光片8、彩膜基板7、液晶层6、TFT基板5、下偏光片4、光阀装置200、增亮膜3、导光板2、反射片9。所述导光板2侧边设有背光光源1，所述光阀装置200设于所述增亮膜3和所述下偏光片4之间，所述彩膜基板1用于将背光光源发出的光线透过彩膜基板1后能够实现图像的彩色化，所述彩膜基板1包括RGB彩膜层(即红色彩膜、绿色彩膜和蓝色彩膜)(图未示出)和矩阵分布的黑色区域(黑矩阵)(未编号)，请参阅图5，所述黑矩阵包括多个黑矩阵阵元52，所述多个黑矩阵阵元52间隔一定距离设置在彩膜基板1上。所述驱动基板12遮光区121正对所述黑矩阵，所述驱动基板12透光区122正对所述黑矩阵阵元间的间隔53(即彩膜基板1上透光的部分)。显而易见的，驱动基板12的遮光区121和透光区122的个数、尺寸、形状、位置均与彩膜基板1的的黑矩阵阵元52和间隔53相匹配。
所述显示装置100还包括公共电极线(图未示出)、多条交叉设置的栅极线(图未示出)和数据线(图未示出)，栅极线和数据线的每个交叉处为一个像素，子像素还包括薄膜晶体管，薄膜晶体管的栅极连接栅极线，源极连接数据线，驱动单元11的输入端连接薄膜晶体管的漏极，输出端连接公共电极线。通过薄膜晶体管给驱动单元11提供驱动信号，这样即可独立控制各子像素显示的内容。
相应的，驱动基板12的遮光区121可以为任何不透光的结构，但从重量、成本、技术成熟度等方面考虑，其可为黑矩阵层，也就是说，可用彩膜基板1中的黑矩阵材料作为遮光区121，黑矩阵材料可以采用遮光性较强的金属或树脂。
请参阅图6，在第二个实施例的显示装置100中，所述光阀装置200设于所述增亮膜3和所述导光板2之间，其工作原理与第一个实施例的显示装置100类似，此处不再赘述。
请参阅图7，在第三个实施例的显示装置100中，所述光阀装置200设于所述反射片9和所述导光板2之间，当所述子像素需要显示黑色时，在驱动单元11的驱动下，两个所述第二遮光板10向所述第一遮光板15并拢，所述第二遮光板10正对所述透光区122，以挡住背光光线通过透光区122进入反射片9，使得该处的子像素显示为黑色。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
