具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制 本发明的范围。
实施例1
本发明实施例提供了一种显示基板，具体地，如图1、图2和图3所示，该显示基板具有阵列排布的多个透光的第一区域，每个第一区域作为一个子像素10，相邻的至少两个子像素10构成一个像素1，每个像素1内的每个子像素10分别对应于不同颜色的背光灯，显示基板还包括多个与每个子像素10一一对应的遮光结构2，每个遮光结构2用于调节一个子像素10的光线透过率。
在一些实施例中，相邻的三个子像素10构成一个像素1，每个像素1内的每个子像素10分别对应于红色、绿色和蓝色的背光灯。
需要说明的是，显示基板必然包括衬底基板，本发明实施例中的衬底基板可以为透明基板，也可以为不透明基板。当衬底基板为透明基板时，各子像素10为形成在透明基板上的通孔或盲孔，或者，选取透明基板上的阵列排布的透明区域直接作为子像素10，无需对透明基板进行挖孔处理；当衬底基板为不透明基板时，各子像素10为形成在不透明基板上的通孔。
上述遮光结构2有多种形式，为了便于本领域技术人员理解和实现，本发明实施例提供两种具体的遮光结构2。
在一些实施例中，第一种遮光结构如图4所示，每个遮光结构2包括至少两个遮光板21，每个遮光板21的光线透过率不同，选择不同的遮光板21以调节子像素10的光线透过率。如图4所示的遮光结构2对子像素10的光线透过率的调节受遮光板21数量的制约，遮光板21数量越多，遮光结构2对子像素10的光线透过率的调节越灵活，但相应的遮光结构2也就越复杂。
在一些实施例中，第二种遮光结构如图2所示，每个遮光结构2包括至少一个遮光板21，遮光板21完全不透光，移动遮光板21以调节子像素10的光线透过率。由于如图2所示的遮光结构2在具有简单结构的条件下即能实现对子像素10的光线透过率的灵活调节，因此，本发明实施例中可选如图2所示的遮光结构2。即每个遮光结构2包括的遮光板21均完全不透光。
需要说明的是，遮光板21位于子像素10的上方或者下方均可，只要其能对子像素10的光线透过率进行调节即可。
本发明实施例对如图2所示的遮光结构2包括的遮光板21的结构和数量进行描述。
在一些实施例中，如图5所示，遮光板21上设置有驱动电极22，驱动电极22与显示基板上设置的线性驱动电机电连接，线性驱动电机根据施加在线性驱动电机上的控制信号驱动遮光板21移动。在一些实施例中，该控制信号包括电流，电流的方向决定遮光板21的移动方向。该控制信号包括电压，电压的大小决定遮光板21的移动距离，从而能够通过调整线性驱动电机上施加的电流的方向或者电压的大小精确调节遮光板21的移动方向或者移动距离，进而简化遮光板21的驱动方法和显示基板的驱动方法。
需要说明的是，线性驱动电机之所以能够驱动遮光板21移动，主要原因在于，在用于向线性驱动电机输出控制信号的控制单元中进行了相应程序的设定。该程序中已经定义了线性驱动电机上施加的电流的方向与遮光板21的移动方向之间的关系，因为电流的方向只有正负两个方向，因此，遮光板21移动的方向就与电流的正负方向一一对应即可；该程序中同时设定了线性驱动电机上施加的电压与遮光板21移动距离之间的函数关系曲线，它们之间的函数关系只是简单的线性关系，当电压增大时、遮光板21的移动距离相应增大，反之则反。
在一些实施例中，遮光结构2包括N个遮光板21，其中，N为大于等于2的正整数，在调节子像素10的光线透过率时，遮光板21依次移动，第n个遮光板21移动至极限位置时，第n+1个遮光板21开始移动，其中，n为大于等于1且小于等于N-1的正整数，从而使得遮光结构2对子像素10的光线透过率的调节更加灵活、更加精确。
此外，本发明实施例中的显示基板还包括与遮光板21相配合的位置传感器，位置传感器用于确定每个遮光板21所处的位置，以便于确定遮光板21移动到下一个位置时需要移动的移动方向和移动距离。当显示基板包括用于驱动遮光板21的线性驱动电机时，通过位置传感器确定每个遮光板21所处的位置，有利于确定遮光板21移动到下一个位置时需要施加在线性驱动电机上的电流的方向和电压的大小。
可选地，如图2、图3和图6所示，显示基板还包括位于相邻两个子像素10之间的腔体3，腔体3用于存放遮光板21。在一些实施例中，每个子像素10的上侧、下侧、左侧或者右侧中的至少一侧设置有腔体3。当子像素10与与其对应的腔体3的位置关系不同时，用于放置在腔体3内的遮光板21的移动方向不同，每个子像素10的上侧或者下侧设置有腔体3时，遮光板21沿上下方向移动，每个子像素10的左侧或者右侧设置有腔体3时，遮光板21沿左右方向移动。本发明实施例中所有子像素10与与其对应的腔体3的位置关系相同，从而使得所有遮光板21的移动方向相同，从而简化遮光板21的驱动方法和显示基板的驱动方法。在一些实施例中，如图6所示，每个子像素10的上侧设置有腔体3，遮光板21沿上下方向(图6中箭头所示方向)移动；如图7所示，每个子像素10的左侧设置有腔体3，遮光板21沿左右方向(图7中箭头所示方向)移动
在一些实施例中，当遮光结构2包括至少两个遮光板21时，遮光板21层叠存放于腔体3内，以使腔体3在平行于衬 底基板的平面内具有较小的尺寸，以有利于在显示基板上设置更多的子像素10，进而提高显示装置的开口率和分辨率。
在一些实施例中，层叠存放于腔体3内的任意相邻两个遮光板21之间设置有润滑结构，润滑结构用于减小相邻两个遮光板21之间的摩擦。在一些实施例中，润滑结构为气体润滑层或者液体润滑层。本发明实施例中，润滑结构为气体润滑层，气体润滑层中的气体为N2，从而使得润滑结构的设置不会对显示基板造成污染，不会影响显示基板的显示效果。
此外，本发明实施例中的遮光板21和腔体3通过微机电系统(Micro-Electro-Mechanical System，简称MEMS)制作形成。由于硅具有机械电器性能优良，且强度、硬度和杨氏模量与铁相当，密度类似铝，热传导率接近钼和钨的优点，因此，本发明实施例中优选遮光板21和腔体3的材料为硅材料。
本发明实施例提供了一种如上所述的显示基板，由于每个像素中的每个子像素对应于不同颜色的背光灯，且通过遮光结构可以调节每个子像素的光线透过率，从而能够调节每个像素透过的不同颜色的光的量，从而能够使每个像素显示不同的颜色，进而无需使用彩膜基板，即能实现显示装置的彩色显示，从而能够降低显示装置的功耗。
此外，本发明实施例还提供了一种显示装置，该显示装置包括以上所述的显示基板。
在一些实施例中，显示装置还包括与遮光结构2相配合的控制单元和驱动单元，其中控制单元用于输出控制信号，驱动单元用于根据控制信号控制遮光结构2移动。
在一些实施例中，当遮光结构2包括至少一个遮光板21，遮光板21完全不透光，且显示基板上设置有用于驱动遮光板21的线性驱动电机时，驱动单元包括纵横交错的栅线和数据线，栅线和数据线围成的第二区域和作为子像素10的第一区域一一对应，每个第二区域内设置有一个薄膜晶体管，薄膜 晶体管的源极电连接数据线，栅极电连接栅线，漏极电连接遮光板21上的驱动电极22，而驱动电极22电连接线性驱动电机，用于向线性驱动电机上施加电压和电流，进而驱动遮光板21的移动，以实现对子像素10的光线透过率的调节。控制单元包括源极驱动电路和栅极驱动电路，源极驱动电路电连接数据线，用于向数据线输入信号，栅极驱动电路电连接栅线，用于向栅线输入信号。
本发明实施例提供了以下两种栅线、数据线和薄膜晶体管的设置方式：
第一种设置方式，栅线、数据线和薄膜晶体管设置于显示基板上，具体可以设置于显示基板上相邻两个子像素10之间的区域上，此时，栅线和数据线围成的第二区域和第一区域重合，作为子像素10。
第二种设置方式，栅线、数据线和薄膜晶体管设置于用于和显示基板对盒的另一基板上，薄膜晶体管的漏极通过导电小球等导电结构与遮光板21上的驱动电极22电连接。
当栅线、数据线和薄膜晶体管采用第一种设置方式时，显示装置的结构更简单，且薄膜晶体管的漏极和驱动电极22位于同一基板上，二者之间直接电连接，或者，通过填充有导电物质的过孔即可实现电连接，使得薄膜晶体管的漏极与驱动电极22之间的电连接更好，因此，本发明实施例中栅线、数据线和薄膜晶体管可采用第一种设置方式。
此外，显示装置还包括用于遮挡栅线、数据线和薄膜晶体管的黑矩阵，以使得栅线、数据线和薄膜晶体管无法被人眼观察到，提高美观性。在一些实施例中，当栅线、数据线和薄膜晶体管采用第一种设置方式时，黑矩阵覆盖于栅线、数据线和薄膜晶体管上方，当栅线、数据线和薄膜晶体管采用第二种设置方式时，黑矩阵位于另一基板上与显示基板上的栅线、数据线和薄膜晶体管相对应的位置处。
在一些实施例中，显示装置还包括多个与子像素10一一 对应的背光灯，控制单元还包括背光灯控制电路，背光灯控制电路用于控制背光灯的开启和关闭。
在显示装置的显示过程中，不同颜色的背光灯可以同时开启或者分时开启，不同颜色的背光灯同时开启，每个像素1中的多个子像素10的混色方式为空间混色方式；不同颜色的背光灯分时开启，每个像素1中的多个子像素10的混色方式为时间混色方式。
本发明实施例中优选不同颜色的背光灯分时开启，每个像素1中的多个子像素10的混色方式为时间混色方式，从而使得显示装置具有较低的功耗。在一些实施例中，某一颜色的背光灯开启时，与该颜色的背光灯一一对应的子像素10均开启，即可以根据每个子像素10需要的光线透过率，调节相应的遮光板21的位置，与其他颜色的背光灯一一对应的子像素10均关闭。
本发明实施例提供的显示装置包括以上所述的显示基板，因此，该显示装置无需使用彩膜基板，即能实现显示装置的彩色显示，从而能够降低显示装置的功耗。
此外，传统的显示装置中，通过液晶分子层和偏光片的配合决定射出显示装置的光线的量，而本发明实施例中使用遮光结构即可调节子像素的光线透过率，因此，本发明实施例中的显示装置无需使用液晶分子层，还可以降低显示装置的成本。
本发明的实施例还提供了一种上述的显示基板的驱动方法，该驱动方法包括：控制每个遮光结构2移动，以调节每个子像素10的光线透过率。由于在之前关于显示基板的结构中已经对如何调节每个子像素10的光线透过率进行了相应的描述，此处不再进行赘述。
在一些实施例中，由之前的描述可知，遮光结构2可以具有多种可能的结构，显示装置的驱动方法也随着遮光结构2的结构的不同而不同。在一些实施例中，当遮光结构2包括 至少一个遮光板21，遮光板21完全不透光，且显示基板上设置有用于驱动遮光板21的线性驱动电机时，控制每个遮光结构2的步骤，包括：向线性驱动电机上施加电压和电流，控制遮光板21的移动距离和移动方向。
本发明的实施例提供了一种显示基板的驱动方法，该驱动方法包括：控制每个遮光结构移动，以调节每个子像素的光线透过率，从而能够调节每个像素透过的不同颜色的光的量，从而能够使每个像素显示不同的颜色，进而无需使用彩膜基板，即能实现显示装置的彩色显示，从而能够降低显示装置的功耗。
实施例2
需要说明的是，本发明的实施例中的行和列是一种相对的概念，本发明的实施例中描述中的行是以水平方向，即本申请中的横向；列是以竖直方向为例进行的说明的，即本申请中的纵向。然而，由于像素为矩阵形式排列，因此当观测的方向不同时，行和列可以互换，横向和纵向也可以互换。
此外，该实施例中，显示面板11可以是诸如传统的显示面板的任何合适的显示面板，而不限于实施例1中描述的显示面板；而遮光结构2可以是实施例1中描述的遮光结构2。
参照图8所示，本发明的实施例提供一种显示装置，该显示装置包括：显示面板11和视力矫正模组12。
显示面板11包括M*N个呈矩阵排列的子像素，用于显示图像信号。
视力矫正模组12设置于显示面板11的显示区域，包括遮光结构2(参见图1至7)，多个遮光结构形成M*N个格栅孔洞123，每一个格栅孔洞123分别对应一个子像素，视力矫正模组12用于调整格栅孔洞123的尺寸。遮光结构2包括可以动的遮光板21(参见图1至7)。
具体的，物理分辨率为m*n的显示面板，包括m行、n列像素，且每一个像素又包括若干子像素，例如：一个像素中可以包括红色子像素(R)、绿色子像素(R)、蓝色子像素(B)三个子像素；再例如：一个像素中还可以包括：红色子像素(R)、绿色子像素(R)、蓝色子像素(B)、白色子像素(W)四个子像素，本发明实例中不限定显示面板包括的像素的数量，也不限定每一个像素中子像素的数量。在一些实施例中，参照图9所示，图9为显示面板11的剖面图，在一些实施例中，显示面板11可以包括：下偏光片201、下基板202、薄膜晶体管203(英文：Thin Film Transistor，简称：TFT)、像素电极204、存储电容205、钝化层206、液晶层207、公共电极208、黑矩阵209、彩膜210、上基板211、上偏光片212。需要说明的是，以上仅为本发明的实施例提供的一种显示面板的实现方式，而本发明的实施例中并不对显示面板的具体结构做限定，只要显示面板能够显示图像信号。
在一些实施例中，视力矫正模组12设置于显示面板11的显示区域，即可以将视力矫正模组12设置于图9所示显示面板的上偏光片212的上方，此外，视力矫正模组为精密结构，例如可以设置保护层对视力矫正模组进行保护，以避免受到外力破坏，因此，在一些实施例中，将视力矫正模组设置于彩膜210与上基板211之间，使用一块基板同时对视力矫正模组和显示面板进行保护，从而可以减小显示装置的厚度以及减少生产成本。视力矫正模组12包括遮光结构2，多个遮光结构2形成M*N个格栅孔洞123，格栅孔洞123与子像素一一对应，所以在每一个子像素的至少一侧都设置有至少一个遮光板21(参见图1至7)。在一些实施例中，视力矫正模组12可以通过微机械(英文：Micro Electro Mechanical System，简称：MEMS)工艺制作形成。其中，MEMS技术是指对微米/纳米材料进行设计、加工、制造、测量和控制的技术。
本发明的实施例提供的显示装置包括：显示面板和视力矫正模组，显示面板用于显示图像信号，视力矫正模组包括 多个遮光结构，所述多个遮光结构形成M*N个格栅孔洞，所述格栅孔洞与子像素一一对应，且视力矫正模组能够调节格栅孔洞的尺寸，因此，本发明实施例提供的显示装置能够通过格栅孔洞尺寸的调整，调整显示面板的每一个子像素的显示面积，进而调整显示装置的显示亮度，使显示装置的显示亮度适合当前用户，所以，本发明的实施例提供的显示装置能够对用户的视力进行保护。
参照图10所示，本发明再一实施例提供一种显示装置100，具体的，该显示装置包括：
显示面板11、视力矫正模组12、视觉信息获取模组13以及视觉状态分析模组14。
视觉信息获取模组13用于获取用户的眨眼频率。在一些实施例中，视觉信息获取模组可以为图像获取装置，例如：摄像机、电荷耦合元件CCD(Charge Coupled Device)相机等。
所述视觉状态分析模组14用于根据所述用户的眨眼频率分析获取所述用户的视觉疲劳状态。
所述视力矫正模组12用于根据所述用户的视觉疲劳状态调整所述格栅孔洞的尺寸。
在一些实施例中，根据用户的眨眼频率分析获取用户的视觉状态可以为：在视觉状态分析模组内存储标准眨眼频率，并将获取的用户眨眼频率与该标准眨眼频率作差，然后根据用户眨眼频率与该标准眨眼频率的差值分析获取用户的视觉疲劳状态。例如：当用户眨眼频率与标准眨眼频率的差值大于一定阈值时判断目前用户的视力处于疲劳状态，则将格栅孔洞的尺寸调整到适当尺寸。当然，还可以进一步根据用户眨眼频率与标准眨眼频率的差值大小将目前用户视力所处疲劳状态划分为若干等级，且不同等级对应的格栅尺寸不同。
在一些实施例中，视觉信息获取模组和视觉状态分析模 组应当设置于显示装置的非显示区域。例如：设置于显示装置的边框上。将视觉信息获取模组13和视觉状态分析模组14设置于显示装置的非显示区域能够避免视觉状态获取模组影响显示装置的正常显示。
上述实施例中，视觉信息获取模组能够获取用户的眨眼频率，视觉状态分析模组能够通过用户的眨眼频率获取用户的视觉疲劳状态，并且视力矫正模组能够根据用户的视觉疲劳状态调整格栅孔洞的尺寸，所以上述实施能够实时监测用户的视觉疲劳状态，并及时调整格栅孔洞的尺寸，因此可以使显示装置更加自动化和智能化对用户的视力进行保护。
在一些实施例中，参照图11所示，上述显示装置100还包括：显示控制模组15；
所述视觉信息获取模组13还用于获取用户到显示装置的距离。在一些实施例中，当视觉信息获取模组用于获取用户的眨眼频率和用户到显示装置的距离时，视觉信息获取模组可以包括：图像获取装置和距离传感器。具体的，图像获取装置可以为摄像机、CCD相机等；距离传感器可以为超声波距离传感器、红外距离传感器等。
所述视觉状态分析模组14还用于根据所述用户到显示装置的距离分析获取所述用户的视觉屈光状态。具体的，所述视觉状态分析模组根据所述用户到显示装置的距离分析获取所述用户的视觉屈光状态可以为：在视觉状态分析模组内存储用户到显示装置的距离与视力屈光状态的函数关系或者对应关系表，当视觉信息获取模组获取用户到显示装置的距离时，将该距离带入函数计算获取该距离对应的视力屈光状态，或者根据用户到显示装置的距离查找对应关系表获取用户视力屈光状态。
所述显示控制模组15用于根据所述用户的视觉屈光状态调整所述显示面板所显示图像的缩放比例。在一些实施例中，可以在显示控制模组内储存不同视觉屈光状态与图像缩放比 例的对应关系表，在获取用户视觉屈光状态后查找对应关系表获取适合当前用户视觉屈光状态的显示面板所显示图像的缩放比例。
上述实施例提供的显示装置能够获取用户的视觉屈光状态，并根据用户的视觉屈光状态调整显示面板的性能参数，因此可以使近视的用户能够在裸眼时看清楚显示器所显示的图像。此外，根据用户的视觉状态对显示面板的性能参数进行调整能够使显示装置更适应用户的视觉屈光状态，从而避免长期使用显示装置造成的视觉疲劳，有益于用户的视力健康。
需要说明的是，当显示面板对图像进行显示时，通常情况下图像会布满整个显示面板，因此，显示面板对图像进行放大时只能够放大显示图像的一部分，或者将图像中的某些元素(例如：显示图像的文字)放大。此外，由于显示面板尺寸的原因，图像并不能无限放大，所以本发明的实施例并不适用于高度近视的用户。
在一些实施例中，参照图12所示，显示装置100还包括：环境监测模组16；
所述环境监测模组16用于检测环境光强度；
所述显示控制模组15还用于根据所述环境光强度调整所述显示面板11的亮度。
具体的，当环境光线较弱(例如：黑夜)，显示模组的显示亮度过高不但浪费显示装置的能源，而且还会对用户的视力健康产生影响，当环境光线较强(例如：阳光下)，显示模组的显示亮度过低则会使图像信号的对比度降低，影响显示模组的显示效果，所以使显示面板的显示亮度适应当前的环境光强度有着重要的意义。而通过实时监测环境光强度，并根据环境光强度调整显示面板的显示亮度，使显示面板的显示亮度适应当前的环境光强度。
在一些实施例中，显示装置还包括：存储模组；
所述存储模组用于存储所述用户的视觉疲劳状态和用户的视觉屈光状态。
具体的，存储模组可以为磁碟、光盘等实体存储装置，也可以为网盘、云盘等虚拟存储装置。将用户的视觉疲劳状态以及用户的视觉屈光状态储存起来，可以根据用户视觉状态分析用户的视力健康状况。
另外，上述任一实施例中的显示装置可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。

根据所述用户的视觉疲劳状态调整所述格栅孔洞的尺寸。
根据本发明的实施例，所述方法还包括：
获取用户到显示装置的距离；
根据所述用户到显示装置的距离分析获取所述用户的视觉屈光状态；
根据所述用户的视觉屈光状态调整所述显示面板所显示图像的缩放比例。
根据本发明的实施例，所述方法还包括：
获取环境光强度；
根据所述环境光强度调整所述显示面板的显示亮度。
根据本发明的实施例，所述方法还包括：存储所述用户的视觉疲劳状态和用户的视觉屈光状态。
本领域普通技术人员可以理解：实现上述方法实施例的全部或部分步骤可以通过程序指令相关的硬件来完成，前述的程序可以存储于计算机可读取存储介质中，该程序在执行时，执行包括上述方法实施例的步骤；而前述的存储介质包括：ROM、RAM、磁碟或者光盘等各种可以存储程序代码的介质。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
