Description

一种显示装置及其驱动方法
本申请要求了2015年2月16日提交的、申请号为201510084820.8的发明名称为“一种显示装置及其驱动方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示技术领域，尤其涉及一种显示装置及其驱动方法。
背景技术
在电子显示领域，一直以来都以追求更清晰的图像为目标，而其主要是通过提高显示分辨率来实现。显示分辨率是显示图像的精密度，指的是显示器所能显示的像素的多少。显示器可以显示的像素越多，画面就越精细，同样的屏幕区域内能显示的信息也越多。
OLED(Organic Light-Emitting Diode，有机发光二极管)显示面板因其可自发光显示、由有机材料制备以及可以被卷曲、折叠等特性而备受青睐。OLED显示面板的发光原理是：在两个电极之间沉积有机发光层，当在两个电极加电后，空穴和电子注入到有机发光层形成激子，退激后有机发光层发光。
但由于OLED的有机发光层一般采用掩模蒸镀的方法制备，即通过掩模板形成有机发光层，而受控于掩模板的精度，有机发光层的无法实现小面积沉积，即通过掩模板形成的像素电极面积较大，进而导致其无法满足高显示分辨率产品的要求。
发明内容
本发明的实施例提供一种显示装置及其驱动方法，所述显示装置能够实现高分辨率的显示效果。
为达到上述目的，本发明的实施例采用如下技术方案：
一方面，本发明实施例提供了一种显示装置，包括显示面板、光学调制器、第一驱动模块和第二驱动模块；其中，所述显示面板包括多个 像素，所述像素包括n个虚拟像素；所述光学调制器设置在所述显示面板的出光侧，包括多个与所述像素对应的光调制单元，所述光调制单元包括：n个分别与所述虚拟像素对应的光调制区域；一帧画面包括n幅亚帧画面；
所述第一驱动模块用于驱动所述显示面板依次显示一帧画面中连续的第n幅亚帧画面；
所述第二驱动模块用于驱动所述光调制单元的第n个光调制区域在所述第n幅亚帧画面中依次为透光区域，其他(n-1)个光调制区域为遮光区域，其中n为大于等于2的正整数。本发明并不局限于这种对应关系。例如，所述第二驱动模块可以驱动所述光调制单元的第m个光调制区域在所述第n幅亚帧画面中依次为透光区域，其余(n-1)个光调制区域为遮光区域，其中m是小于等于n的正整数。
另一方面，本发明实施例提供了一种显示装置的驱动方法，包括：
驱动所述显示面板依次显示一帧画面中连续的第n幅亚帧画面；
驱动所述光调制单元的第n个光调制区域在所述第n幅亚帧画面中依次为透光区域，其他(n-1)个光调制区域为遮光区域，其中n为大于等于2的正整数。
本发明的实施例提供一种显示装置及其驱动方法，显示面板依次显示连续一帧画面中的n幅亚帧画面，光调制单元的第n个光调制区域在第n幅亚帧画面中依次为透光区域，其他(n-1)个光调制区域为遮光区域。即显示面板在显示任意一幅亚帧显示画面，像素的一个虚拟像素对应的光调制区域透光，该虚拟像素实现显示；其他的虚拟像素由于光调制区域遮光而没有成为有效像素。即与现有的显示相比，将一帧显示画面拆分为多个亚帧画面分别进行显示，从视觉上使得用户感受到显示分辨率的提升，相对于传统的改变显示面板的制作工艺，降低像素面积来提升显示分辨率的方法，本发明实施例无需对显示面板的制作方法进行改进就可以实现视觉显示分辨率的提升，大大降低了工艺难度和为实现高分辨率显示付出的成本。

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。
本发明实施例提供了一种显示装置100，如图1-图2所示，包括显示面板10、光学调制器20、第一驱动模块30和第二驱动模块40；其中，显示面板10包括多个像素11。每个像素包括n个虚拟像素。光学调制器20设置在显示面板10的出光侧，包括多个与像素11对应的光调制单元21。每一个光调制单元21包括：n个分别与虚拟像素相对应的光调制区域；一帧画面包括n幅亚帧画面；第一驱动模块用于驱动显示面板依次显示一帧画面中连续的第n幅亚帧画面；第二驱动模块用于驱动光调制单元的第n个光调制区域在第n幅亚帧画面中依次为透光区域，其他(n-1)个光调制区域为遮光区域，其中n为大于等于2的正整数。
需要说明的是，显示面板和光调制单元均包括多层薄膜以及层结构，本发明实施例中对显示面板以及光调制单元的具体结构不作限定。图2中的像素和光调制单元只是示例的说明。每个像素可以是红、绿、蓝等不同颜色的像素，红、绿、蓝三个像素组成一个像素单元。当然，像素单元还可以是包括红、绿、蓝、白或红、绿、蓝、黄等四种不同颜色的像素。本发明实施例对像素的颜色、形状以及各像素的具体排布方式均不作限定。具体的，第一驱动模块和第二驱动模块可以为相同的模块，其可以执行多种功能。也可以是不同的驱动模块，各自执行各自的功能。图1中以第一驱动模块30和第二驱动模块40分别为两个不同的驱动模块为例进行说明。此处需要说明的是，虽然第一驱动模块和第二驱动模块的功能不同，但对于显示装置而言，第一驱动模块和第二驱动模块必须配合驱动，以使得驱动光调制单元的n个光调制区域在n幅亚帧画面中依次为透光区域，其他光调制区域为遮光区域。
本发明实施例中，每个像素包括n个虚拟像素，光调制单元包括：n个分别与虚拟像素对应的光调制区域；对应的，一帧画面包括n幅亚帧画面，其中在n幅亚帧画面中，显示面板上的图像信息不同。即在连续的n幅亚帧画面中，每一亚帧间的图像信息一般来说是不同的，从而各个有效的虚拟像素显示不同的图像，进一步提升显示画面的精细度。
显示面板包括多个像素，光学调制器包括与像素对应的光调制单元。此处，光调制单元可以是包括与像素一一对应的光调制单元，也可以是一个光调制单元对应多个像素，下面以光调制单元与像素一一对应 为例进行说明。需要说明的是，所述虚拟像素是指像素的几何面积部分，不一定为像素的二分之一，且只有在像素包括两个虚拟像素时，虚拟像素可以为像素的二分之一。像素包括n个虚拟像素，光调制单元包括：n个分别与虚拟像素对应的光调制区域。第一驱动模块用于驱动显示面板依次显示一帧画面中连续的n幅亚帧画面；第二驱动模块用于驱动光调制单元的第n个光调制区域在第n幅亚帧画面中依次为透光区域，其他(n-1)个光调制区域为遮光区域，其中n为大于等于2的正整数，即n可以是2、3、4等。
具体的，以n等于3为例。如图3所示，像素11包括3个虚拟像素，即第一虚拟像素111、第二虚拟像素112和第三虚拟像素113。如图4所示，光调制单元21包括与像素的3个虚拟像素一一对应的3个光调制区域，即第一光调制区域211、第二光调制区域212以及第三光调制区域213。一帧画面包括三幅亚帧画面，在第一驱动模块驱动显示面板依次显示一帧画面中连续的3幅亚帧画面，光调制单元的3个虚拟像素在每一幅亚帧中仅有一个透光，其他两个遮光。具体，如图5所示，在显示面板显示一帧画面中的第一幅亚帧画面时，第一虚拟像素111对应的第一光调制区域透光，第二光调制区域212和第三光调制区域213遮光；在显示面板显示第二幅亚帧画面时，第二虚拟像素112对应的第二光调制区域透光，第一光调制区域211和第三光调制区域213遮光；在显示面板显示第三幅亚帧画面时，第三虚拟像素113对应的第三光调制区域透光，第一光调制区域211和第二光调制区域212遮光。
这里需要说明的是，现有的显示面板的驱动频率为60Hz，即一秒钟显示60帧画面，由于现有的一个像素在一帧画面完全为有效显示像素，则一帧画面的显示时间为1/60s；则在像素包括3个虚拟像素的情况下，显示面板的驱动频率可以为180Hz，即一秒钟显示180帧画面，一幅亚帧画面的显示时间为1/180s，一帧画面的显示时间为1/60s。
本发明实施例在显示一幅亚帧画面时，使得与像素的一个虚拟像素相对应的光调制区域透光，该虚拟像素实现显示；其他的虚拟像素由于光调制区域遮光而没有成为有效像素。即与现有的显示相比，将一帧画面通过多幅亚帧画面分别进行显示，从视觉上使得用户感受到显示分辨 率的提升，相对于传统的改变显示面板的制作工艺、降低像素面积来提升显示分辨率的方法，本发明实施例无需对显示面板的制作方法进行改进就可以实现视觉显示分辨率的提升，大大降低了工艺难度和为实现高分辨率显示付出的大幅成本。
本发明实施例中，所述显示面板可以为液晶显示面板、有机发光二极管显示面板以及电子纸显示面板等。由于有机发光二极管显示面板采用掩模蒸镀，本身其像素面积较大，难以满足高分辨率的要求。优选的，在显示面板为有机发光二极管显示面板的情况下，可以避免有机发光二极管显示装置实现高分辨率要求制作工艺复杂的问题。
进一步的，有机发光二极管显示面板为双面显示面板，有机发光二极管显示面板的两侧分别设置有一个光学调制器。则双面显示的显示图像都可以满足高分辨率的要求。当然，有机发光二极管显示面板可以是底发射型显示装置也可以是顶发射型显示装置，本发明实施例不作具体限定。
可选的，有机发光二极管显示面板包括阵列基板和封装基板，其中，封装基板为玻璃基板或为封装薄膜。具体的，对有机发光二极管显示面板的具体封装等结构问题，本发明实施例不作具体限定。
优选的，如图6所示，像素11包括两个虚拟像素，即像素包括第一虚拟像素111和第二虚拟像素112。需要说明的是，第一虚拟像素和第二虚拟像素在各像素的位置和大小可以是不定的，图6为示例的一种，本发明实施例仅以图6所示的为例进行详细说明。如图7所示，光调制单元包括两个分别与虚拟像素对应的光调制区域，即光调制单元21包括第一光调制区域211和第二光调制区域212。其中，第一光调制区域211与第一虚拟像素111对应，第二光调制区域212与第二虚拟像素112对应。当然，第一光调制区域也可以是与第二虚拟像素对应，则第二光调制区域可以是与第一虚拟像素对应，本发明实施例以第一虚拟像素与第一光调制区域对应，第二虚拟像素与第二光调制区域对应为例进行详细说明。
对应的，一帧画面包括两幅亚帧画面。第一驱动模块驱动显示面板显示一帧画面中的第一幅亚帧画面时，第二驱动模块具体用于驱动光调 制单元的两个光调制区域分别为透光区域和遮光区域；第一驱动模块驱动显示面板显示一帧画面中的第二幅亚帧画面时，第二驱动模块具体用于驱动光调制单元各光调制区域的透光性与显示面板在显示第一幅亚帧画面时该光调制区域的透光性相反。
具体的，如图8所示，第一驱动模块驱动显示面板10显示一帧画面中的第一幅亚帧画面时，第二驱动模块驱动光调制单元21的第一光调制区域211为透光区域，第二光调制区域212为遮光区域；第一驱动模块30驱动显示面板10显示一帧画面中的第二幅亚帧画面时，第二驱动模块40驱动光栅21的第一光调制区域211为遮光区域，第二光调制区域212为透光区域。此时，显示面板的驱动频率可以为120Hz。即可以是将现有的一帧画面通过两幅亚帧画面倍速后分别显示，从视觉上使得用户感受到显示分辨率的提升。
可选的，显示面板的虚拟像素呈阵列式排列；如图6所示，第一虚拟像素111和第二虚拟像素112矩阵排列。第一驱动模块驱动显示面板显示一帧画面中的第一帧画面时，第二驱动模块具体用于驱动光调制单元的每一行任意相邻的两个光调制区域和/或每一列任意相邻的两个光调制区域分别为透光区域和遮光区域。
具体的，若光学调制器包括设置在每一行光调制区域的条形光阀，即一个光调制单元为对应一行虚拟像素的条形光阀，则一个条形光阀控制一行光调制区域透光或遮光。如图8所示，以光调制单元包括两个光调制区域为例，第一驱动模块驱动显示面板显示一帧画面中的第一幅亚帧画面时，第二驱动模块驱动任意一行光调制区域为透光，则与之相邻的一行光调制区域为遮光，此时，同一行的光调制区域的透光性相同，任意相邻的两行光调制区域的透光性相反，则每一列任意相邻的两个光调制区域分别为透光区域和遮光区域。
另外，在光学调制器包括设置在每一行光调制区域的条形光阀22的情况下，如图10所示，还可以通过两个条形光阀使得位于相邻两行像素中相邻的两行光调制区域(即对应两个条形光阀22)均为遮光区域，其中，图10a为相邻的两行像素示意图，即包括相邻的四行虚拟像素，图10b为相邻两行像素中相邻的两行光调制区域均为遮光区域的示意 图，即两个条形光阀分别控制相邻两个像素中相邻的两行光调制区域。或者，还可以如图11所示，使得一个条形光阀22对应相邻两行虚拟像素中相邻的两个光调制区域，即一个条形光阀控制两行光调制区域，从而使得位于相邻两行像素中相邻的两行光调制区域(即对应一个条形光阀22)均为遮光区域。
若光学调制器包括设置在每一列光调制区域的条形光阀，即一个光调制单元为对应一列虚拟像素的条形光阀，则一个条形光阀控制一列光调制区域透光或遮光，可以参照图10所示。第一驱动模块驱动显示面板显示一帧画面中的第一幅亚帧画面时，第二驱动模块用于驱动任意一列光调制区域为透光，与之相邻的一列光调制区域为遮光。此时，同一列的光调制区域的透光性相同，任意相邻的两列光调制区域的透光性相反，则每一行任意相邻的两个光调制区域分别为透光区域和遮光区域。在光学调制器包括设置在每一列光调制区域的条形光阀的情况下，还可以使得位于相邻两列像素中相邻的两列光调制区域均为遮光区域。或者，还可以使得条形光阀对应相邻列虚拟像素中相邻的两个光调制区域，可以参照图11所示。
或者，光学调制器还可以包括设置在每个光调制区域的光阀，则在光调制单元与虚拟像素一一对应的情况下，每一个光调制单元均通过一个光阀控制器来控制透光或遮光，从而可以控制使得显示面板上任意一个虚拟像素显示图像或不显示图像。在光学调制器包括设置在每个光调制区域的光阀的情况下，通过控制每个光阀，也可以实现如图9所示的任意相邻的两个虚拟像素分别为透光区域和遮光区域，即每一行任意相邻的两个光调制区域和每一列任意相邻的两个光调制区域分别为透光区域和遮光区域，以在空间上产生视觉补偿，以提高显示效果。图9所示以像素包括两个虚拟像素为例。
可选的，光阀可以为液晶光阀、MEMS(微机电系统)光阀或电子纸光阀等。具体本发明实施例对光阀的具体结构不做具体限定。需要说明的是，若光阀为液晶光阀，即光学调制器为液晶光学调制器，光学调制器包括上基板、下基板以及位于上基板和下基板之间的液晶，可以通过设置电极控制液晶的偏转使光调制单元透光或不透光，其原理与现有的 液晶显示装置类似，只需要实现透光和遮光功能即可。电子纸光阀的原理与现有的电子纸显示器的原理类似，MEMS光阀可以参照现有技术，这里不作赘述。
可选的，显示装置还包括触控电极，触控电极用于检测触控位置。在本发明实施例中，所述显示装置为触控显示装置，其可以根据触控信号控制显示面板的图像显示。具体的，触控电极可以是包括触控传感电极和触控驱动电极，并且触控电极具体的形状设置可以参照现有的显示装置，这里不作赘述。
由于光学调制器设置在显示面板的出光侧，为了加强触控信号的感应，优选的，触控电极设置在光学调制器上。
具体的，由于光阀可以为液晶光阀、MEMS光阀或电子纸光阀，即光学调制器可以是液晶光学调制器、MEMS光学调制器或电子纸光学调制器，则当触控电极设置在光学调制器上根据具体的情况可以有多种不同方式。以液晶光学调制器为例，则液晶光学调制器可以是包括上基板、下基板以及位于上基板和下基板之间的液晶，其中，触控驱动电极和触控传感电极可以是同时设置在上基板，也可以是同时设置在下基板，还可以是分别形成在上基板和下基板。对于触控驱动电极和触控传感电极设置在光学调制器上的具体设置，本发明实施例不作限定，仅以上述为例进行说明。
具体的，若光阀为液晶光阀，则液晶光学调制器的上基板和下基板上还分别设置有第一偏光片和第二偏光片。且下面，本发明实施例以光栅为液晶光栅、显示面板为有机发光二极管显示面板为例详细说明显示装置的制作方法。
步骤10、形成有机发光二极管显示面板。
具体的，上述步骤10具体包括：将透明衬底采用标准方法清洗，之后沉积金属层(可以是沉积Mo，并沉积200nm)，图形化形成栅金属层还可以同时形成对位图案，包括栅极和栅线；沉积绝缘层(可以是沉积SiO2，并沉积150nm)；沉积半导体层(可以是沉积IGZO，并沉积40nm)，图形化形成有源层；沉积金属层(可以是沉积Mo，并沉积200nm)，图形化形成源漏金属层，包括源极、漏极以及数据线；沉积钝化层(可 以是沉积SiO2，沉积300nm)；沉积像素电极(可以是沉积ITO，沉积40nm)，并图形化；最后旋涂沉积亚克力系材料并光刻、固化出像素界定层，约1.5um。至此，在透明衬底上形成阵列的像素。
采用等离子体处理像素的表面；进而在OLED/EL-有机金属薄膜沉积高真空系统中热蒸发蒸镀有机材料(依次可以是蒸镀形成空穴注入层、空穴传输层、发光层、电子传输层及电子注入层)，其整体厚度为100-300nm；之后蒸镀阴极金属薄层，阴极可采用LiF：Al层等，约为500-1000nm，蒸镀结束之后进行封装并切割，完成有机发光二极管显示面板的制作。这里，LiF：Al层为Al薄膜的上面沉积LiF薄膜，其中，LiF薄膜的厚度大约为0.8nm。LiF薄膜主要用于增强电子注入。
步骤20、形成液晶光学调制器。
具体的，上述步骤20具体包括：下基板衬底采用标准方法清洗，之后沉积金属Mo，沉积200nm，并图形化形成对位图案；沉积绝缘层(可以是沉积SiO2，沉积150nm)；沉积像素电极(可以是沉积ITO，沉积60nm)；上基板采用标准方法清洗之后，沉积公共电极(可以是沉积ITO，沉积60nm)，而后对上下基板进行取向摩擦工艺，并灌入液晶将上基板和下基板对盒并切割，形成液晶光学调制器。
步骤30、将有机发光二极管显示面板和液晶光学调制器贴合，并绑定电路。
在液晶光学调制器的正反两面贴上偏光片，根据有机发光二极管显示面板以及液晶光学调制器的对位图案将有机发光二极管显示面板与该液晶光学调制器对位压合；之后绑定驱动电路等柔性线路板，并调试程序，形成最终完整的模组。
需要说明的是，有机发光二极管显示面板和液晶光学调制器的类型以及制作方法均有多种，本发明实施例仅以上述制作方法为例进行详细说明，其他类型的显示面板以及液晶光学调制器结合现有制作方法并参考上述制作方法，本发明实施例不一一列举说明。
本发明实施例提供了一种显示装置的驱动方法，包括：
驱动显示面板依次显示一帧画面中连续的n幅亚帧画面；
驱动光调制单元的第n个光调制区域在第n幅亚帧画面中依次为透 光区域，其他(n-1)个光调制区域为遮光区域，其中n为大于等于2的正整数。
具体的，显示装置可以是通过第一驱动模块驱动显示面板依次显示一帧画面中连续的n幅亚帧画面；通过第二驱动模块驱动光调制单元的第n个光调制区域在第n幅亚帧画面中依次为透光区域，其他光调制区域为遮光区域。具体的，第一驱动模块和第二驱动模块可以为相同的模块，其可以执行多种功能。也可以是不同的驱动模块，各自执行各自的功能。图1中以第一驱动模块30和第二驱动模块40分别为两个不同的驱动模块为例进行说明。此处需要说明的是，虽然第一驱动模块和第二驱动模块的功能不同，但对于显示装置而言，第一驱动模块和第二驱动模块必须配合驱动，以使得驱动光调制单元的n个光调制区域在n幅亚帧画面中依次为透光区域，其他n-1个光调制区域为遮光区域。
具体的，以n等于3为例。如图3所示，像素11包括3个虚拟像素，即第一虚拟像素111、第二虚拟像素112和第三虚拟像素113。则如图4所示，光调制单元21包括3个与像素的3个虚拟像素一一对应的光调制区域，即第一光调制区域211、第二光调制区域212以及第三光调制区域213。在第一驱动模块驱动显示面板依次显示一帧画面中连续的3幅亚帧画面，一帧画面包括三幅亚帧画面；光调制单元的3个虚拟像素在每一幅亚帧中仅有一个透光，其他两个遮光。具体，如图5所示，在显示面板显示一帧画面中的第一幅亚帧画面时，第一虚拟像素111对应的第一光调制区域透光，第二光调制区域212和第三光调制区域213遮光；在显示面板显示第二幅亚帧画面时，第二虚拟像素112对应的第二光调制区域透光，第一光调制区域211和第三光调制区域213遮光；在显示面板显示第三幅亚帧画面时，第三虚拟像素113对应的第三光调制区域透光，第一光调制区域211和第二光调制区域212遮光。
这里需要说明的是，现有的显示面板的驱动频率为60Hz，即一秒钟显示60帧画面，由于现有的一个像素在一帧画面完全为有效显示像素，则一帧画面的显示时间为1/60s；则在像素包括3个虚拟像素的情况下，显示面板的驱动频率可以为180Hz，即一秒钟显示180帧画面，一幅亚帧画面的显示时间为1/180s，一帧画面的显示时间为1/60s。
本发明实施例通过使得一幅亚帧画面中，像素的一个虚拟像素对应的光调制区域透光，该虚拟像素实现显示，其他的虚拟像素由于光调制区域遮光而没有成为有效像素。即与现有的显示相比将一帧画面通过为多幅亚帧画面分别进行显示，从视觉上使得用户感受到显示分辨率的提升，相对于传统的改变显示面板的制作工艺，降低像素面积来提升显示分辨率的方法，本发明实施例无需对显示面板的制作方法进行改进就可以实现视觉显示分辨率的提升，大大降低了工艺难度和为实现高分辨率显示付出的大幅成本。
可选的，像素包括两个虚拟像素，光调制单元包括两个分别与虚拟像素对应的光调制区域时；一帧画面包括两幅亚帧画面，驱动显示面板依次显示一帧画面中连续的n幅亚帧画面；驱动光调制单元的n个光调制区域在n幅亚帧画面中依次为透光区域，其他n-1个光调制区域为遮光区域具体包括：
驱动显示面板显示一帧画面中的第一幅亚帧画面时，驱动光调制单元的两个光调制区域分别为透光区域和遮光区域；
驱动显示面板显示一帧画面中的第二幅亚帧画面时，驱动光调制单元各光调制区域的透光性与显示面板在显示第一幅亚帧画面时该光调制区域的透光性相反。
如图6所示，像素11包括两个虚拟像素，即像素包括第一虚拟像素111和第二虚拟像素112。需要说明的是，第一虚拟像素和第二虚拟像素在各像素的位置和大小可以是不定的，图6为示例的一种，本发明实施例仅以图6所示的为例进行详细说明。如图7所示，光调制单元21包括两个分别与虚拟像素11对应的光调制区域，即光调制单元21包括第一光调制区域211和第二光调制区域212。其中，第一光调制区域211与第一虚拟像素111对应，第二光调制区域212与第二虚拟像素112对应。
如图8所示，第一驱动模块驱动显示面板10显示一帧画面中的第一幅亚帧画面时，第二驱动模块驱动光调制单元21的第一光调制区域211为透光区域，第二光调制区域212为遮光区域；第一驱动模块30驱动显示面板10显示一帧画面中的第二幅亚帧画面时，第二驱动模块40 驱动光栅21的第一光调制区域211为遮光区域，第二光调制区域212为透光区域。此时，显示面板的驱动频率可以为120Hz。即可以是将现有的一帧画面通过两幅亚帧画面倍速后分别显示，从视觉上使得用户感受到显示分辨率的提升。
可选的显示面板的虚拟像素呈阵列式排列；第一驱动模块驱动显示面板显示一帧画面中的第一帧画面时，第二驱动模块具体用于每一行任意相邻的两个光调制区域和/或每一列任意相邻的两个光调制区域分别为透光区域和遮光区域。
具体的，若光学调制器包括设置在每一行光调制区域的条形光阀，即一个光调制单元为对应一行虚拟像素的条形光阀，则一个条形光阀控制一行光调制区域透光或遮光。如图8所示，以光调制单元包括两个光调制区域为例，第一驱动模块驱动显示面板显示一帧画面中的第一幅亚帧画面时，第二驱动模块驱动任意一行光调制区域为透光，则与之相邻的一行光调制区域为遮光，此时，同一行的光调制区域的透光性相同，任意相邻的两行光调制区域的透光性相反，则每一列任意相邻的两个光调制区域分别为透光区域和遮光区域。
另外，在光学调制器包括设置在每一行光调制区域的条形光阀22的情况下，如图10所示，还可以通过两个条形光阀使得位于相邻两行像素中相邻的两行光调制区域(即对应两个条形光阀22)均为遮光区域，其中，图10a为相邻的两行像素示意图，即包括相邻的四行虚拟像素，图10b为相邻两行像素中相邻的两行光调制区域均为遮光区域的示意图，即两个条形光阀分别控制相邻两个像素中相邻的两行光调制区域。或者，还可以如图11所示，使得一个条形光阀22对应相邻两行虚拟像素中相邻的两个光调制区域，即一个条形光阀控制两行光调制区域，从而使得位于相邻两行像素中相邻的两行光调制区域(即对应一个条形光阀22)均为遮光区域。
若光学调制器包括设置在每一列光调制区域的条形光阀，即一个光调制单元为对应一列虚拟像素的条形光阀，则一个条形光阀控制一列光调制区域透光或遮光，可以参照图10所示。第一驱动模块驱动显示面板显示一帧画面中的第一幅亚帧画面时，第二驱动模块用于驱动任意一列 光调制区域为透光，与之相邻的一列光调制区域为遮光，此时，同一列的光调制区域的透光性相同，任意相邻的两列光调制区域的透光性相反，则每一行任意相邻的两个光调制区域分别为透光区域和遮光区域。且在光学调制器包括设置在每一列光调制区域的条形光阀的情况下，还可以使得位于相邻两列像素中相邻的两列光调制区域均为遮光区域。或者，还可以使得条形光阀对应相邻列虚拟像素中相邻的两个光调制区域，可以参照图11所示。
或者，光学调制器还可以包括设置在每个光调制区域的光阀，则在光调制单元与虚拟像素一一对应的情况下，每一个光调制单元均通过一个光阀控制器透光或遮光，从而可以控制使得显示面板上任意一个虚拟像素显示图像或不显示图像。且在光学调制器包括设置在每个光调制区域的光阀的情况下，通过控制每个光阀，也可以实现如图9所示的任意相邻的两个虚拟像素分别为透光区域和遮光区域，即每一行任意相邻的两个光调制区域和每一列任意相邻的两个光调制区域分别为透光区域和遮光区域，以在空间上产生视觉补偿，以提高显示效果。图9所示以像素包括两个虚拟像素为例。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
