目前，市面上常见的一类显示装置为液晶显示装置。常规液晶显示装置的结构一般包括液晶显示面板和位于液晶显示面板入光侧的背光模组。其中，液晶显示面板包括：相对设置以形成液晶盒的阵列基板和滤光基板，位于阵列基板和滤光基板之间的液晶，位于阵列基板远离滤光基板一侧的第一偏光片，以及位于滤光基板远离阵列基板一侧的第二偏光片，其中，阵列基板相对滤光基板更加靠近背光模组，第一偏光片和第二偏光片的偏光方向正交。液晶显示面板包括多个像素单元，每个像素单元包括 颜色各不相同的多个子像素。同一像素单元的子像素按照一定比例混光，可以使像素单元显示出人眼可见的彩色。此类常规液晶显示装置由于自身结构特点，存在画面对比度欠佳和暗态漏光的技术缺陷。
为改善上述缺陷，相关技术提出一种采用双屏驱动技术的液晶显示装置。与上述常规液晶显示装置的主要不同在于，如图1a所示，其显示面板100’包括层叠设置的调光液晶面板2’和显示液晶面板1’。其中，显示液晶面板1’与上述液晶显示面板的结构和工作原理类似，调光液晶面板2’位于显示液晶面板1’的入光侧且位于背光模组的出光侧(背光模组在图中未示出，背光模组的出光见图中的虚线箭头所示)，包括呈阵列排布的多个调光像素020’。每个调光像素020’作为一个调光单元，与显示液晶面板1’的若干个子像素010’位置相对，用于控制经由该调光像素020’射入显示液晶面板1’相应区域的背光的方向和强弱。
相关技术的液晶显示装置可以实现对画面较为精细的区域调光，其原理为，根据所显示画面在不同区域的灰阶，调整调光液晶面板2’的相应调光像素020’的透光性(即允许背光透过的方向和/或强弱)。例如，对于画面亮度较高的区域，调光液晶面板2’的相应调光像素020’的透光率也调整地相对较高；而对于画面亮度较低的区域，调光液晶面板2’的相应调光像素020’的透光率也调整的相对较低；对于画面显示为黑色的区域，调光液晶面板2’的相应调光像素020’的透光率调整至基本为零。该类液晶显示装置与上述的常规液晶显示装置相比，可以克服画面暗态漏光的缺陷，对比度显著提升，从而为用户带来较佳的观看体验。尤其是，当液晶显示装置进行HDR(High-Dynamic Range，高动态范围图像)显示时，区域调光使画面的亮度范围更广，低灰阶过渡更加自然，显示效果更佳。
如图1b所示，上述调光液晶面板的阵列基板21’，其具有多个狭缝结构(狭缝结构在图中未示出)的公共电极层213’包括沿列向交替排列的两类畴3a’、3b’，该阵列基板21’对应上述调光像素020’的每个调光区20’与两类畴3a’、3b’均有交叠。这样，上述调光像素020’的液晶分子在公共电极层和像素电极层(图中未示出)所形成电场的驱动下，可以呈现出轴对称的两种取向，从而使得显示面板在水平方向上的可视角度呈现轴对称性。
为了提升显示面板的透过率以及降低调光液晶面板的电容负载，调光液晶面板的分辨率通常设计地较低。当显示面板的尺寸设计的较大时，例如设计为65英寸或者更大尺寸时，每个调光像素的尺寸也较大。当人眼在侧视角观看画面时，由于同一个 调光像素的公共电极层和像素电极层在不同畴所形成的电场方向不同，因此，液晶的偏转方向也不同，对光的折射效果也不同，当从侧视角观看画面时，两类畴的透过率存在一定的差异，从而导致人眼可以看到明显的条纹，尤其是当画面显示为白色时，条纹黄蓝相间，观看体验很不理想。
为解决相关技术中的技术问题，本公开实施例提供一种阵列基板、调光液晶面板及显示面板。
在本公开实施例中，调光像素是针对调光液晶面板而言，其整体的结构设计用于控制经由该调光像素射入显示液晶面板相应区域的背光的方向和强弱。调光区是针对阵列基板而言，由相邻的栅线和数据线交叉界定，与调光像素具有一一对应的关系，阵列基板在调光区的结构设计是调光像素结构设计的一部分。
如图2a和图3a所示，本公开一实施例提供了一种阵列基板21，包括：
具有多个狭缝结构2130的第一透明电极层213，该第一透明电极层213包括面积相等的多个畴3，该多个畴3包括至少两类畴(如图中的畴3a、3b，不同类畴以不同的灰度区分)，该至少两类畴呈马赛克状排布，其中，位于同一类畴的狭缝结构2130的延伸方向相同，位于不同类畴的狭缝结构2130的延伸方向不同(图3a中，不同畴以虚线示意分界)；
沿行向延伸的多根栅线211以及沿列向延伸的多根数据线212，多根栅线211与多根数据线212交叉界定出呈阵列状排布的多个调光区20，每个调光区20与上述的至少两类畴相交叠(即有面积重叠)。
本公开实施例的阵列基板21应用于调光液晶面板中。参见图5所示，调光液晶面板2除阵列基板21外，还包括与阵列基板21间隔设置的对向基板22，以及，位于阵列基板21与对向基板22之间的液晶层23。调光液晶面板2在工作时，背光射入阵列基板21，经过液晶层23后从对向基板22射出。
在本公开的一些实施例中，上述的调光液晶面板为AD-SDS(ADvanced Super Dimension Switch，高级超维场转换技术，简称ADS)模式的液晶面板。图3a所示为阵列基板在一个调光区的结构示意。本公开实施例的阵列基板除第一透明电极层213外还包括第二透明电极层214，第二透明电极层214与第一透明电极层213绝缘间隔设置，并且，第二透明电极层214相比第一透明电极层213更加靠近阵列基板的衬底(图中未示出)。在一些实施例中，第二透明电极层214可以为像素电极层，包括多 个面状的像素电极，具有狭缝结构2130的第一透明电极层213为公共电极层。在另一些实施例中，第二透明电极层也可以为公共电极层，具有狭缝结构的第一透明电极层为像素电极层，包括多个具有狭缝结构的像素电极。
如图2a和图3a所示，阵列基板的结构还包括设于栅线211和数据线212交叉处且分别与栅线211和数据线212连接的薄膜晶体管215，具体的，薄膜晶体管215的栅极与栅线211连接，薄膜晶体管215的源极与数据线212连接，薄膜晶体管215的漏极与像素电极连接。此外，阵列基板的结构还包括公共电极线218，用于将公共电压信号较为均匀的传输给作为公共电极层的第一透明电极层213或第二透明电极层214。该实施例中，公共电极线218设置在相邻两根数据线212之间。
调光液晶面板在工作时，第一透明电极层213的狭缝结构2130的边缘会产生电场，第一透明电极层213与第二透明电极层214之间也会产生电场，从而形成多维电场。该多维电场能够使大部分液晶分子产生偏转，从而提高了调光液晶面板的工作效率和透过率。
如图2a所示，在该实施例中，沿行向排列的薄膜晶体管215设置于各自所相邻数据线212的同一侧，沿列向排列的薄膜晶体管215交替的设置于所相邻数据线212的两侧，由数据线212交替的向两侧像素电极传输数据信号。从图中可以看出，在垂直于阵列基板21的方向上，各个薄膜晶体管215位于同一类畴3a内，各个薄膜晶体管215的漏极在同一类畴内与调光像素的像素电极连接。这种驱动设计，相比列反转驱动方式(列反转驱动设计中，各个薄膜晶体管均设置在相邻数据线的同一侧)，可以有效减少显示画面的抖动纹。
为实现显示装置可视视角的对称性，通常，调光区20的结构会采用多畴设计。如图2a和图3a所示，每个调光区20与第一透明电极层213的多个畴3相交叠而且与至少两类畴相交叠，并且，第一透明电极层213的位于不同类畴的狭缝结构2130的延伸方向呈现一定的对称性。这样，在电场驱动下，同一个调光像素中，不同类畴的液晶分子的取向也相应呈现出一定的对称性。
在本公开实施例中，第一透明电极层213的畴3的划分密度不限，可以根据显示产品的具体规格尺寸来进行相应设计。在一些实施例中，畴的面积与调光区的面积的比值大于等于1/16，且小于等于1/2。图2a所示的实施例中，畴3的面积与调光区20的面积的比值大致为1/8。第一透明电极层213所包含畴3的类数也不限，例如，可以如图2a所示包括两类畴3a、3b，也可以包括三类畴或者更多类的畴。
在图2a所示的实施例中，该多个畴3的形状尺寸相同且均为等腰三角形，例如可以为正三角形，该多个畴3包括两类畴3a、3b，并且，该两类畴3a、3b呈马赛克状排布。即，对于处于非边缘处的畴3a，其被三个畴3b包围，同样，对于处于非边缘处的畴3b，其被三个畴3a包围。两类畴3a、3b呈马赛克状排布，将不同类畴均匀打乱，从宏观上可以改善显示装置显示画面的条纹不良。
在图2a和图3a所示的实施例中，每个调光区20共与第一透明电极层213的十个畴3(参见图中标号①～⑩的畴)相交叠，且每个调光区20与第一透明电极层213的两类畴均有交叠。而在图1b所示的相关技术中，每个调光区20’与透明电极层213’的四个畴相交叠，且每个调光区20’与透明电极层213’的两类畴3a’、3b’均有交叠。对比图2a和图1b可以看出，在本公开实施例中，与调光区20相交叠的畴3的数量更多，这相当于对调光液晶面板的调光像素的不同取向的出光进行了更为细小的区域划分，从而可以达到均匀混色的效果，有效改善了显示装置显示画面的条纹不良。
如图2a所示，在本公开的该实施例中，栅线211沿行向呈折线波形状延伸，包括呈周期排列的多个第一折线单元2110，第一折线单元2110包括以列向为对称轴对称设置的两个第一直线段03；数据线212沿列向呈折线波形状延伸，包括呈周期排列的多个第二折线单元2120，第二折线单元2120包括中心对称的第一子段2120a和第二子段2120b，第一子段2120a和第二子段2120b分均包括以行向为对称轴对称设置的两个第二直线段04。采用该设计，可以使得调光液晶面板的调光像素的形状与显示液晶面板的子像素的形状(通常为矩形)差异较大，从而有利于消除摩尔纹。该实施例中，各个数据线212的形状完全相同，并且在相邻的数据线212之间设置了公共电极线218，公共电极线218沿列向也呈折线波形状延伸，包括呈周期排列的多个第三折线单元2180，第三折线单元2180包括中心对称的第三子段2180a和第四子段2180b，第三子段2180a和第四子段2180b均包括以行向为对称轴对称设置的两个第三直线段05。
如图2a所示，在本公开的一些实施例中，公共电极线218和数据线212的形状大致相对列向对称，这样，在一个调光区内，公共电极层位于公共电极线两侧的部分面积基本相等，因此，信号一致性较好，更有利于改善显示面板画面的横纹现象。如图2b所示，在本公开的另一些实施例中，公共电极线218和数据线212的形状也可以大致相同。
此外，在该实施例中，在垂直于阵列基板21的方向上，第一折线单元2110的端 点A1、A2与第二折线单元2120的端点B1、B2或中点B3相重合，第一折线单元2110的中点A3与第三折线单元2180的端点C1、C2或中点C3相重合。每个调光区20由相邻两根栅线211的一个周期的第一折线单元2110和相邻两根数据线212的半个周期的第二折线单元2120界定。
如图2a所示，在该实施例中，畴3的形状为等腰三角形，在垂直于阵列基板的方向上，每个第一直线段03与两个畴3的侧边(即两个前述等腰三角形的位于同一侧的腰)大致重合，第二折线单元2120和第三折线单元2180在列向上的正投影大致等于前述等腰三角形的高的四倍。
在本公开的该实施例中，如图2a所示，一个调光区20的面积大致等于八个畴3的面积。与一个调光区20相交叠的两类畴3a、3b的面积相等且大致为调光区20面积的一半。每个调光区与十个畴相交叠，与单个畴的最大交叠面积等于该单个畴的面积，即大致为调光区面积的八分之一。与相关技术相比，调光区与单个畴的最大交叠面积减小了四分之一，因此，能够实现良好的混色效果，有效改善了条纹不良。
如图2a和图3a所示，在垂直于阵列基板的方向上，位于同一类畴的第二直线段04和第三直线段05与狭缝结构2130的延伸方向相同。采用该设计，第一透明电极层213的狭缝结构2130在调光区20内的排布更为优化，可以产生更多的边缘电场，有利于实现调光液晶面板透过率的最大化。在一些实施例中，狭缝结构2130与列向所呈锐角夹角的范围大于等于7°，且小于等于11°。
如图3a、图3b和图3c所示，在本公开的一个实施例中，第一透明电极层213包括多个干电极2131，以及分布于干电极2131两侧的多个支电极2132。其中，每个干电极2131位于相邻两个不同类的畴的狭缝结构2130之间。在一个畴内，支电极2132与狭缝结构2130的延伸方向相同，相邻支电极2132被狭缝结构2130间隔。此外，多个干电极2131中，至少一个干电极2131沿行向延伸。如图3b所示，对于该沿行向延伸的干电极2131，其两侧的多个支电极2132相对该干电极2131对称设置。如图3b所示，对于延伸方向与行向呈一定夹角的干电极2131，其两侧的多个支电极2132相对该干电极2131呈不对称设置。
上述沿行向延伸的干电极2131，其线宽可以设计地小于显示液晶面板的栅线的线宽。当包含该阵列基板的调光液晶面板与显示液晶面板组装后，如图4中的示意，在垂直于显示液晶面板的方向上，该沿行向延伸的干电极2131能够落入显示液晶面板的栅线101的边缘内侧，即该沿行向延伸的干电极2131在显示液晶面板上的正投影 完全重叠于栅线101内部，从而被栅线101遮挡(显示液晶面板的栅线101不属于阵列基板21的结构，这里仅用于示意与干电极2131的相对位置关系)。
由于干电极2131两侧的狭缝结构2130的延伸方向不同，因此，调光像素的液晶分子在干电极2131两侧的偏转方向也不同，干电极2131处可能存在漏光现象。将干电极2131的线宽设计为小于显示液晶面板的栅线101的线宽，并且通过显示液晶面板的栅线101进行遮挡，可以有效减少甚至避免在干电极2131处的漏光现象，从而进一步提升显示画面的品质。
值得一提的是，在本公开的一些其它实施例中，在垂直于显示液晶面板的方向上，沿行向延伸的干电极2131也可以与栅线101在宽度上部分重叠，从而也能在一定程度上起到减少漏光的效果。
参照图5所示，本公开实施例还提供一种调光液晶面板2，包括前述任一技术方案的阵列基板21、与该阵列基板21间隔设置的对向基板22，以及，位于阵列基板21与对向基板22之间的液晶层23。
以75英寸的调光液晶面板为例，如图6所示，左图为本公开图2a所示实施例调光液晶面板的画面模拟局部图，右图为图1b所示相关技术调光液晶面板的画面模拟局部图。可以看出，相关技术调光液晶面板的模拟画面可以看到明显的条纹，而本公开实施例调光液晶面板的模拟画面基本看不到条纹，显示品质显著提升。
如图7所示，本公开实施例还提供一种显示面板100，包括前述实施例的调光液晶面板2，以及，位于调光液晶面板2一侧的显示液晶面板1。具体的，显示液晶面板1位于调光液晶面板2的出光侧。
该显示面板应用于显示装置，可以实现对画面较为精细的区域调光，对比度表现出色，并且与相关技术相比，画面的条纹不良也得到有效改善，因此，画面品质较高，从而显著提升了用户体验。其中，显示装置的具体产品类型不限，例如可以为显示器、平板电脑、笔记本电脑、电视机、ATM设备、电子纸、展示屏等等。
在一些实施例中，如前，调光液晶面板的阵列基板的第一透明电极层包括多个干电极，以及分布于干电极两侧的多个支电极，每个干电极位于相邻两个不同类的畴的狭缝结构之间。在一个畴内，支电极与狭缝结构的延伸方向相同，相邻支电极被狭缝结构间隔。至少一个干电极沿行向延伸，且沿行向延伸的干电极的线宽小于显示液晶面板的栅线的线宽，在垂直于显示液晶面板的方向上，沿行向延伸的干电极落入显示 液晶面板的栅线的边缘内侧。在另一些实施例中，在垂直于显示液晶面板的方向上，沿行向延伸的干电极也可以与显示液晶面板的栅线部分重叠。采用这些实施例的设计方案，可以有效减少甚至避免在干电极处的漏光现象，从而进一步提升显示画面的品质。
至此，已经详细描述了本公开的各实施例。为了避免遮蔽本公开的构思，没有描述本领域所公知的一些细节。本领域技术人员根据上面的描述，完全可以明白如何实施这里公开的技术方案。
虽然已经通过示例对本公开的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本公开的范围。本领域的技术人员应该理解，可在不脱离本公开的范围和精神的情况下，对以上实施例进行修改或者对部分技术特征进行等同替换。本公开的范围由所附权利要求来限定。
