Abstract

一种彩膜基板、显示装置及其检测方法，其可解决现有的显示面板故障定位困难，检测效率低的问题。所述彩膜基板包括排成阵列的多个子像素，每个子像素中设有彩色滤光膜，并且至少部分列子像素为标记列子像素（3），标记列子像素（3）中的部分子像素的彩色滤光膜（21）的形状与该列中其余子像素的彩色滤光膜（22）的形状不同。显示装置包括彩膜基板。彩膜基板可用于显示装置中，尤其适合用于采用双侧GOA电路的显示装置中。

Description

彩膜基板、显示装置及其检测方法 技术领域
本发明属于显示装置检测技术领域，具体涉及彩膜基板、显示装置及其检测方法。
背景技术
GOA(阵列基板行驱动技术，Gate Driver On Array)电路是指直接制备在阵列基板上的栅极线驱动电路。GOA电路包括多级依次连接的移位寄存器，每个移位寄存器驱动一条栅极线，并为下一级移位寄存器提供开启信号，从而GOA电路整体上可实现使栅极线逐条导通的目的。从空间占用等方面考虑，也有部分显示装置采用双侧GOA电路，即在阵列基板两侧各设有一个GOA电路，分别用于驱动奇数行和偶数行的栅极线。
当GOA电路的某个位置存在短接、断开等故障时，将导致故障位置之后的各级移位寄存器不能正常工作，进而导致显示异常。对于采用双侧GOA电路的显示面板，若其某一侧的GOA电路出现故障，则会如图1所示，从显示面板的某个位置开始，之后的子像素出现隔行显示不良(也称“分屏异显不良”)。当出现这种现象时，可以知道是一侧的GOA电路出现问题，但由于子像素行数很多，故无法确定出现故障的是奇数行子像素还是偶数行子像素，也就无法确定是哪侧的GOA电路出现问题。因此，在检测过程中只能拆开显示面板，对两侧的GOA电路都进行分析检测，从而导致故障定位困难，检测效率低。
发明内容
本发明针对现有的显示面板故障定位困难，检测效率低的问题，提供一种易于迅速定位故障的彩膜基板和显示装置及其检测方法。

附图说明
图1为示出现有的显示面板中出现隔行异常的示意图。
图2为本发明的实施例的一种彩膜基板的结构示意图。
具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
如图2所示，本发明的一个实施例提供一种彩膜基板，其包括排成阵列的多个子像素，每个子像素中设有彩色滤光膜。
彩膜基板包括多个子像素，在其组成显示装置后，每个子像素对应显示装置的一个子像素。彩膜基板的每个子像素包括彩色滤光膜和围绕彩色滤光膜的黑矩阵，彩色滤光膜用于使透过的光变为对应的颜色，而黑矩阵用于阻止不希望的光透过。
例如，同列子像素的彩色滤光膜的颜色相同。
也就是说，同一列的子像素可以为相同的颜色，这样比较便于彩色滤光膜的制备，且当一列子像素颜色相同时不能通过颜色区分出不同行，故本实施例的方案对这种彩膜基板更适用。
本实施例的彩膜基板中，至少部分列子像素为标记列子像素3，该标记列子像素3中有部分子像素的彩色滤光膜与该列中其余子像素的彩色滤光膜形状不同。
在现有的彩膜基板中，所有子像素的彩色滤光膜的形状都是相同的(当然颜色可不同)，故无法区分出不同的行，给故障定位造成困难。而如图2所示，在本实施例的彩膜基板中，至少有一部分列的子像素为“标记列子像素3”，在这些标记列中，至少有一部分子像素的彩色滤光膜的形状与其余的子像素的彩色滤光膜的形状不同，因此，可以通过将这些形状不同的子像素作为标记点，判断出其所处的行，进而进行故障定位。当然，在其他“非标记列”的子像素中，同列中全部子像素的彩色滤光膜的形状是相同的。
显然，从减小对显示效果影响的角度考虑，以上彩色滤光膜之间的形状的差别应尽量小，只要在显微镜下能将二者区分开即可。例如，如图2所示，标准子像素的彩色滤光膜21为缺角的矩形，而标记子像素的彩色滤光膜22为完整的矩形。
当然，本实施例中的彩色滤光膜形状的不同不限于此。例如，可在某子像素的彩色滤光膜的部分位置上叠加设置其他额外的标记(如小三角、小圆形、小星星等)，这样该子像素的彩色滤光膜的形状也与其他子像素不同。再如，也可以“挖去”某子像素的彩色滤光膜的一部分，并在其中填入其他的彩色滤光膜，这样也可使子像素的彩色滤光膜的形状不同。总之，在两个子像素中，只要不是全部彩色滤光膜的结构(不包括颜色)都完全相同，就可认为二者的彩色滤光膜的形状是不同的。
例如，标记列子像素3中的部分子像素为标准子像素11，其余为标记子像素12。例如，除标记列子像素3外的其余子像素均为标准子像素11。各标准子像素11的彩色滤光膜21的形状相同，而标记子像素12的彩色滤光膜22与标准子像素11的彩色滤光膜21的形状不同。
显然，彩色滤光膜的形状的改变会影响显示效果，为了尽量减少彩色滤光膜的形状的变化对显示效果的影响，在本实施例中，例如，彩膜基板中的多数子像素可仍为常规的正常子像素(标准子像素11)，这些标准子像素的彩色滤光膜21的形状都相同，故显 示效果不会受到影响。其余的子像素为用于进行区分的标记子像素12，标记子像素12的彩色滤光膜22的形状与标准子像素11的彩色滤光膜21的形状不同，故可被区分出来。
例如，各标记子像素12的彩色滤光膜22的形状相同。
显然，当各标记子像素12的彩色滤光膜22的形状相同时，其仍可起到区分的作用，同时这样的标记子像素12易于制造，且对显示效果的影响最小。
例如，作为本实施例的另一种方式，标记子像素12分为至少两种类型，且不同类型的标记子像素12的彩色滤光膜22的形状不同。
也就是说，各标记子像素12的彩色滤光膜22的形状可不完全相同。例如，若标准子像素11的彩色滤光膜21为上述缺角的矩形，则某些标记子像素12的彩色滤光膜22可以为完整的矩形，某些标记子像素12的彩色滤光膜22的边上可以为缺一块的矩形，某些标记子像素12的彩色滤光膜22的部分位置上设有额外的标记等。通过多种标记子像素12的混合使用，可实现更好的区分效果。例如，若标记子像素12分为第一类型和第二类型，则在彩膜基板中，可以使得标准子像素11对应于第3M(M为正整数)行，第一类型的标记子像素12对应于第(3M+1)行，第二类型的标记子像素12对应于第(3M+2)行。
例如，在标记列子像素3中，每间隔N个标准子像素11设有至少一个标记子像素12。
在本实施例中，例如，在标记列子像素3中，可以每隔N个标准子像素11设有一个标记子像素12。这样，只要N的个数不是太大，就可用标记子像素12为基准来确定不同的行。例如，若N＝3，且标记子像素12位于4M(M为正整数)行，则标准子像素11位于以下的第一行即为(4M+1)行，以下的第二行即为(4M+2)行，以下的第三行即为(4M+3)行。之所以优选采用以上方案，是因为这样可在标记子像素12的形式最简单(全部标记子像素12的彩色滤光膜22形状相同)的情况下，实现足够的区分效果。
例如，以上的N为1，则每间隔一个标准子像素11设有一个标记子像素12。也就是说，标记列子像素3可以按照“标准子像素11-标记子像素12-标准子像素11-标记子像素12”的方式逐一轮流排列。这样，在标记列子像素3中，必然是标准子像素11和标记子像素12中的一种全部位于奇数行，另一种全部位于偶数行。最常用的需要区分行数的情况是，在采用双侧GOA电路的显示装置的检测过程中，通常只要区分出奇偶行即可，而以上形式的彩膜基板即可用最简单的结构实现该目的。
当然，显示装置也可能需要按其他的方式区分行，此时只要相应调整标记子像素12的情况即可。
例如，若显示装置两侧分别各有两个GOA电路，则栅线的驱动也就变成每4个为一循环的方式了。相应的，此时可采用上述的N＝3的方式，即每4行中有一个标记子像素12，通过该标记子像素12即可间接确定其他的行。或者，此时也可采用上述标记子像素12分为多种类型的形式，例如，可设置三种不同类型的标记子像素12，使它们分别对应(4M+1)行、(4M+2)行、(4M+3)行，而标准子像素11对应4M行，这样也可完全区分每个GOA电路所对应的行。
具体的，通过组合设置标记子像素12的位置、类型等，可以实现很多种不同的区分行情况，在此就不再逐一详细描述。
例如，标记列子像素3的数量为一列。例如，标记列子像素3为彩膜基板最外侧的两列子像素中的一列。
也就是说，如图2所示，标记列子像素3只要有一列即可，例如，该标记列子像素3位于彩膜基板的最左侧。显然，在很多情况下，通过一列标记列子像素3已经可以达到区分不同行的目的，故为了减小对显示效果的影响，标记列子像素3的数量应尽量的少。若标记列子像素3位于彩膜基板的最外侧，则可很容易地被找到，方便识别。
当然，存在多列标记列子像素3也是可行的，或者标记列子像素3位于彩膜基板最外侧以外的其他位置(例如，中间位置) 也是可行的。例如，可存在多列标记列子像素3，不同列的标记列子像素3中的标记子像素12所在的行号不同，第一列标记列子像素3中标记子像素12在第一行，第二列标记列子像素3中的标记子像素12在第二行等，这样通过多列标记列子像素3的共同作用可进行更准确的判断(例如可判断出故障所在列的具体列号等)。
本发明的另一实施例提供一种显示装置，其包括上述的彩膜基板。
该显示装置可以为有机发光二极管(OLED)显示装置、液晶显示装置、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，在此不再详细限定。
该显示装置还可以包括与彩膜基板对盒的阵列基板，阵列基板包括多条栅极线和两个GOA电路，每条栅极线对应彩膜基板的一行子像素，两个GOA电路中的一个驱动奇数行栅极线，另一个驱动偶数行栅极线。在此情况下，例如，在该彩膜基板中，上述标准子像素11和标记子像素12轮流排列在标记列子像素3中。
也就是说，本实施例的彩膜基板可以用于采用双侧GOA电路的显示装置中。
本发明的另一实施例提供一种显示装置的检测方法，该显示装置为上述采用双侧GOA电路的显示装置，该检测方法具体包括：在检测过程中，通过标记列子像素3中的标记子像素12区分显示装置的奇数行和偶数行。
也就是说，在采用双侧GOA电路的显示装置的检测过程中，若一侧的GOA电路出现故障，则表现为显示装置从某位置开始出现隔行显示异常，而此时只要观察出现异常的行对应的是标准子像素11还是标记子像素12，即可确定其是奇数行还是偶数行，进而确定出现故障的是哪侧的GOA电路，从而直接对该GOA电路进行检测分析，以达到准确定位故障、提高检测效率的目的。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领 域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
