Description

彩色滤光片及其制作方法、显示面板、显示装置及其驱动方法 技术领域
本发明的至少一个实施例涉及一种彩色滤光片及其制作方法、显示面板、显示装置及其驱动方法。
背景技术
光栅式3D(即立体)显示装置主要包括：显示屏及叠加在显示屏正面或背面的光栅，显示屏包括矩阵式排布的多个子像素，光栅包括交替排列的遮光条和挡光条。进行3D显示时，向显示屏的一半子像素施加左眼图像信号，向另一半子像素施加右眼图像信号，并使被施加左眼图像信号的子像素与被施加右眼图像信号的子像素沿行方向交替排列。
当人位于适当的位置观察显示画面时，由于左右眼之间具有一定的距离，即左眼与右眼的观察角度存在差异，加上光栅的遮光条对子像素产生一定的遮挡作用，使得左眼仅能接收到透过被施加左眼图像信号的子像素的光线，右眼仅能接收到透过被施加右眼图像信号的子像素的光线，从而实现了左眼图像光线与右眼图像光线在空间上的分离。由于左眼图像与右眼图像为从不同角度拍摄的画面，因此左眼图像与右眼图像在人脑中叠加，就产生了3D显示的效果。

为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例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的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例，都属于本发明保护的范围。
在研究中，本申请的发明人注意到，显示屏的子像素的颜色通常按照红(R)、绿(G)、蓝(B)的次序循环排布，一个红色子像素、一个绿色子像素和一个蓝色子像素组成一个像素，每个子像素均包括对应设置在彩色滤光片上一个彩色色阻。出于对高分辨率的追求，子像素的尺寸越来越小，对 制作彩色光阻的掩膜版的制作精度和对位精度要求越来越高，造成制作彩色滤光片的难度加大。
本发明的至少一个实施例提供了一种彩色滤光片，如图1和图2所示，该彩色滤光片包括基板1，位于基板1上的黑矩阵2，以及多个彩色色阻；该黑矩阵2包括沿行方向的多条第一黑矩阵条21和沿列方向的多条第二黑矩阵条22，多条第一黑矩阵条21和多条第二黑矩阵条22交错形成矩阵式排布的多个网格区域；所述多个彩色色阻位于多个网格区域内，该多个彩色色阻包括红色(R)色阻、绿色(G)色阻和蓝色(B)色阻。
上述彩色滤光片上彩色色阻的排布为：包括矩阵式排布的多个像素区域A，每个像素区域A包括一R子像素区域A1、一G子像素区域A2和一B子像素区域A3，R子像素区域A1包括偶数个R亚子像素区域，每个R亚子像素区域内设置有一个R色阻(参见图1和图2中的R1或R2)，G子像素区域A2包括偶数个G亚子像素区域，每个G亚子像素区域内设置有一个G色阻(参见图1和图2中的G1或G2)，B子像素区域A3包括偶数个B亚子像素区域，每个B亚子像素区域内设置有一个B色阻(参见图1和图2中的B1或B2)。
在本发明实施例中，基板1例如可以为玻璃基板、石英基板或塑料基板等。黑矩阵2例如可以采用黑色遮光树脂材料。本发明实施例不做限定。
相应的，本发明的至少一个实施例提供了上述彩色滤光片的制作方法，该方法包括以下步骤S1和步骤S2。
步骤S1：在基板1上形成黑矩阵2，该黑矩阵2包括沿行方向的多条第一黑矩阵条21和沿列方向的多条第二黑矩阵条22，多条第一黑矩阵条21和多条第二黑矩阵条22交错形成矩阵式排布的多个网格区域。
步骤S2：在黑矩阵2所形成的多个网格区域内形成多个彩色色阻，该多个彩色色阻包括红色色阻、绿色色阻和蓝色色阻，该彩色滤光片上的彩色色阻的排布可参考以上对彩色滤光片上彩色色阻的排布的描述，在此不再重复描述。
相对应的，本发明的至少一个实施例还提供了一种显示面板，其包括以上所述的彩色滤光片。该显示面板可以为液晶面板或OLED面板等。本发明实施例不做限定。
在至少一个实施例中，该显示面板可以包括阵列基板20和与阵列基板20相对设置的对盒基板30，如图10所示。例如，阵列基板20与对盒基板30可以通过封框胶40密封在一起以形成液晶盒，在液晶盒中填充有液晶材料。
在至少一个实施例中，彩色滤光片可以与阵列基板相对设置；或者彩色滤光片可以设置在阵列基板上。例如，图10示出了一种彩色滤光片与阵列基板相对设置的显示面板的结构示意图。如图10所示，显示面板可以包括相对设置的阵列基板20和对盒基板30，彩色滤光片设置于对盒基板30上，彩色滤光片包括的上述基板1可以作为对盒基板30的衬底基板，黑矩阵2设置于基板1上且面向阵列基板20。例如，当彩色滤光片设置在阵列基板上时，显示面板中与阵列基板相对设置的对盒基板可以为透明基板。本发明实施例不做限定。
相对应的，本发明的至少一个实施例还提供了一种3D显示装置，如图3所示，该3D显示装置包括以上所述的显示面板3，及与该显示面板3叠加在一起的狭缝光栅4。本发明实施例中所述狭缝光栅4设置在显示面板3的出光面上。显示面板3包括矩阵式排布的多个像素，每个像素包括一R子像素、一G子像素和一B子像素，R子像素包括偶数个R亚子像素，G子像素包括偶数个G亚子像素，B子像素包括偶数个B亚子像素。
需要说明的是，为了突出3D显示时狭缝光栅4对显示面板3显示面中像素的遮挡和透过作用，图3所示出的显示面板3被简化为显示面中像素的排布，且狭缝光栅4与显示面板3显示面之间具有一定的距离D，实际上狭缝光栅4与显示面板3是贴覆在一起的，狭缝光栅4与显示面板3显示面之间的距离D取决于显示面板3靠近狭缝光栅4一侧的基板的厚度。
相对应的，本发明的至少一个实施例还提供了上述显示装置的驱动方法，如图3和图4所示，该驱动方法包括：在一帧的时间内，向每个R子像素的一半R亚子像素、每个G子像素的一半G亚子像素和每个B子像素的一半B亚子像素施加左眼图像信号，同时向每个R子像素的另一半R亚子像素、每个G子像素的另一半G亚子像素和每个B子像素的另一半B亚子像素施加右眼图像信号；同时驱动狭缝光栅4形成交替的遮光条41和透光条42，使在预设观察位置观察显示装置时，经过被施加右眼图像信号的亚子像素的 光线被遮光条41遮挡而无法进入左眼，经过被施加左眼图像信号的亚子像素的光线被透光条42透过而进入左眼，经过被施加左眼图像信号的亚子像素的光线被遮光条41遮挡而无法进入右眼，经过被施加右眼图像信号的亚子像素的光线被透光条42透过而进入右眼。
利用上述像素排布结构与驱动方法，当人在特定位置观察显示装置时，由于左右眼之间存在视差，因此进入左眼的光线仅为经过被施加左眼图像信号的亚子像素的光线，进入右眼的光线仅为经过被施加右眼图像信号的亚子像素的光线，左眼图像与右眼图像在人脑中交叠合成，产生3D立体的图像效果。
如图5所示，一种3D显示装置的彩色滤光片按照R子像素、B子像素和G子像素的顺序循环排列，进行3D显示时，相邻的两个子像素一个被施加左眼图像信号、一个被施加右眼图像信号，进而可实现3D显示。本发明实施例中的彩色滤光片也是按照R子像素、B子像素和G子像素的顺序循环排列的，不同的是，每个子像素又被细分为颜色相同的偶数个亚子像素，各亚子像素的尺寸可设置为与图5中一个子像素的尺寸相同，每个子像素所包括的偶数个亚子像素被平均分为两部分，一部分被施加左眼图像信号，另一部分被施加右眼图像信号，进而实现了3D显示功能。
在实现3D显示的基础上，本发明实施例中亚子像素的尺寸能够设置为与图5中一个子像素的尺寸相同，使得本发明实施例中的3D显示装置的分辨率与图5所示的3D显示装置的分辨率相同，同时由于本发明实施例中每个子像素所包括的亚子像素颜色相同且位置相邻，因此一个子像素所包括的全部亚子像素能够在同一步骤中形成，即一个步骤能够完成一种颜色的子像素的制作，又因为本发明实施例中一个子像素所包括的亚子像素的尺寸与图5中一个子像素的尺寸相同，因此本发明实施例中单个子像素的尺寸较大，使得对制作子像素所用的掩膜版的精细程度的要求降低，且掩膜版的对位更容易，降低了彩色滤光片的制作难度。
本发明实施例中的彩色滤光片中，红色子像素区域A1所包括的红色亚子像素区域的数目(即所设置的R色阻的数目)、绿色子像素区域A2所包括的绿色亚子像素区域的数目(即所设置的G色阻的数目)和蓝色子像素区域A3所包括的蓝色亚子像素区域的数目(即所设置的B色阻的数目)可以 设置为相同。
在不明显影响显示品质的前提下，在本发明的至少一个实施例中，彩色滤光片每个子像素区域包括两个颜色相同的亚子像素区域(即设置两个颜色相同的彩色色阻)。例如，R子像素区域A1包括两个R亚子像素区域(即设置两个R色阻R1和R2)，G子像素区域A2包括两个G亚子像素区域(即设置两个G色阻G1和G2)，B子像素区域A3包括两个B亚子像素区域(即设置两个B色阻B1和B2)。当然，本发明实施例不限于此。
此时，驱动显示装置时，需向各子像素中的一个亚子像素施加左眼图像信号，另一个亚子像素施加右眼图像信号，且一行亚子像素中，被施加左眼图像信号的亚子像素与被施加右眼图像信号的亚子像素交替排列，即被施加左眼图像信号的亚子像素为R1、G1和B1，被施加右眼图像信号的亚子像素为R2、G2和B2。
换个角度讲，由于奇数列子像素由R1、G1和B1组成，偶数列子像素由R2、G2和B2组成，因此驱动时，在一帧的时间内，向奇数列亚子像素R1、G1和B1施加左眼图像信号，同时向偶数列亚子像素R2、G2和B2施加右眼图像信号；同时驱动狭缝光栅4形成交替的遮光条41和透光条42，使在预设观察位置观察显示装置时，经过偶数列亚子像素R2、G2和B2的光线被遮光条41遮挡而无法进入左眼，经过奇数列亚子像素的光线R1、G1和B1被透光条42透过而进入左眼，即左眼仅能看到奇数列亚子像素R1、G1和B1；经过奇数列亚子像素R1、G1和B1的光线被遮光条41遮挡而无法进入右眼，经过偶数列亚子像素R2、G2和B2的光线被透光条42透过而进入右眼，即右眼仅能看到偶数列亚子像素R2、G2和B2，从而实现左右眼图像的光线在空间上的分离。
当然，也可以向奇数列亚子像素R1、G1和B1施加右眼图像信号，同时向偶数列亚子像素R2、G2和B2施加左眼图像信号；同时驱动狭缝光栅4形成交替的遮光条41和透光条42，使在预设观察位置观察显示装置时，经过奇数列亚子像素R1、G1和B1的光线被遮光条41遮挡而无法进入左眼，经过偶数列亚子像素R2、G2和B2的光线被透光条42透过而进入左眼，即左眼仅能看到偶数列亚子像素R2、G2和B2；经过偶数列亚子像素R2、G2和B2的光线被遮光条41遮挡而无法进入右眼，经过奇数列亚子像素R1、 G1和B1的光线被透光条42透过而进入右眼，即右眼仅能看到奇数列亚子像素R1、G1和B1，从而实现左右眼图像的光线在空间上的分离。
以每个子像素包括两个颜色相同的亚子像素，即彩色滤光片上每个子像素区域内设置两个颜色相同的彩色色阻为例，制作该彩色滤光片的过程例如可包括以下步骤S01至S04，下面逐一介绍这些步骤。
步骤S01：如图6所示，在基板1上形成包括黑矩阵2的图形。
步骤S02：如图7所示，通过构图工艺在R子像素区域A1内形成R色阻R1和R2。
例如，在基板旋涂R色阻材料，之后采用子像素宽度两倍于图5中彩色滤光片的子像素宽度的掩膜版对R色阻材料进行曝光和显影，去除部分R色阻材料，保留待形成R子像素区域A1内的R色阻材料，完成R色阻R1和R2的制作。所形成的R色阻R1和R2位于黑矩阵2所构成的相邻的两个网格区域内。
步骤S03：如图8所示，通过构图工艺在G子像素区域A2内形成G色阻G1和G2。
例如，在基板旋涂G色阻材料，之后采用子像素宽度两倍于图5中彩色滤光片的子像素宽度的掩膜版对G色阻材料进行曝光和显影，去除部分G色阻材料，保留待形成G子像素区域A2内的G色阻材料，完成G色阻G1和G2的制作。所形成的G色阻G1和G2位于黑矩阵2所构成的相邻的两个网格区域内。
步骤S04：如图9所示，通过构图工艺在B子像素区域A3内形成B色阻B1和B2。
例如，在基板旋涂B色阻材料，之后采用子像素宽度两倍于图5中彩色滤光片的子像素宽度的掩膜版对B色阻材料进行曝光和显影，去除部分B色阻材料，保留待形成B子像素区域A3内的B色阻材料，完成B色阻B1和B2的制作。所形成的B色阻B1和B2位于黑矩阵2所构成的相邻的两个网格区域内。
需要说明的是，本发明实施例对R子像素、G子像素和B子像素的形成顺序并不限定。
另外，上述制作过程所采用的方法为颜料分散法，基于本发明实施例所 提供的彩色滤光片的结构，本领域的技术人员还能够采用印刷法、浆料喷射法、有机材料电镀法等方法进行制作。
需要注意的是，图4中所示出的仅为显示装置中一行亚子像素的排布情况，实际上显示装置是包括多行按照图4所示进行排布的亚子像素的。
本发明实施例中，假设光栅4的狭缝的宽度Ww、光栅单元的宽度Ws(即一个遮光条与一个透光条的宽度之和)和光栅4与显示面板3显示面之间的距离D可根据显示面板3中单个子像素的宽度Wp(即属于同一子像素的偶数个亚子像素的宽度之和，图3以两个亚子像素为例进行说明)、人左眼与右眼之间的距离Q和显示面板3显示面与人眼之间的距离L(即前述的“观察位置”)计算得到。
通常情况下，可以认为人左眼与右眼之间的距离Q和显示面板3显示面与人眼之间的距离L是不变的，则Ww、Ws和D由像素的宽度Wp决定，Wp的值为单个子像素所包括的亚子像素的宽度之和，单个亚子像素的宽度与图5中单个子像素的宽度相同，将Wp的值分别代入公式：
Figure PCTCN2015070532-appb-000001
Figure PCTCN2015070532-appb-000002
(其中K为常系数)和
Figure PCTCN2015070532-appb-000003
中，能够分别计算得到Ww、Ws和D的值。
将显示面板3(包括彩色滤光片)和光栅4按照计算得到的尺寸设置，人在显示装置正面的各个视点(如：视点1和视点2)观察画面时，由于光栅4的遮光条41的遮挡作用，左眼透过光栅4的透光条42看到的亚子像素仅为R1、G1和B1，右眼透过光栅4的透光条42看到的亚子像素仅为亚子像素R2、G2和B2。驱动亚子像素R1、G1和B1显示左眼图像(或右眼图像)，驱动亚子像素R2、G2和B2显示右眼图像(或左眼图像)，由于左眼图像与右眼图像为从不同角度拍摄得到的图像，因此人双眼所接收的左眼图像与右眼图像叠加后能够得到立体的图像。
需要说明的是，本发明实施例所提供的显示装置可以为液晶面板、电子纸或OLED(Organic Light-Emitting Diode，有机发光二极管)面板等，适用于手机、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。
本发明实施例所提供的彩色滤光片及其制作方法、显示面板、显示装置及其驱动方法中，彩色滤光片的每个子像素区域内设置有偶数个颜色相同的彩色色阻，每个彩色色阻对应一个亚子像素区域，通过向每个子像素的一半亚子像素施加左眼图像信号，同时向另一半亚子像素施加右眼图像信号，实现3D显示。可见，本发明实施例中亚子像素的尺寸能够与图5所示的彩色滤光片中子像素的尺寸相同，也就是说，本发明实施例中彩色滤光片的分辨率与图5中彩色滤光片的分辨率相同，但是子像素的尺寸能够制作为图5中彩色滤光片的子像素尺寸的至少两倍，并且一种颜色的子像素中的各亚子像素的颜色均相同，能够在同一步骤下形成，因此制作本发明实施例中的彩色滤光片所需要的掩膜版的制作精度和对位精度较低，从而彩色滤光片制作难度较低。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2014年9月28日递交的中国专利申请第201410509950.7号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
