另外,在下面的详细描述中,为便于解释,阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地,一个或多个实施例在没有这些具体细节的情况下也可以被实施。
相关技术中,液晶显示面板中电极结构10的图形设计为内部开设有狭缝11,且狭缝11四周闭合,如图1所示;但这种电极结构10周边光效较差,从而容易出现显示不良。
为解决上述问题,本公开提供了一种电极结构,此电极结构可用于液晶显示面板中,并可作为液晶显示面板的像素电极或公共电极使用;举例而言,此电极结构可为ITO电极。详细说明,如图2所示,电极结构可包括在第一方向Y上依次排布的第一电极部20、导电连接部22及第二电极部21;其中:
第一电极部20可包括在第一方向Y上延伸的第一连接条201以及在第一方向Y上间隔排布的多个第一电极条202,第一连接条201具有在第二方向X上相对的第一侧和第二侧,多个第一电极条202位于第一连接条201的第一侧并与第一连接条201连接,且相邻第一电极条202中远离第一连接条201的端部之间呈开口状,也就是说,相邻第一电极条202中远离第一连接条201的端部之间无连接。
需要说明的是,前述提到多个第一电极条202在第一方向Y上间隔排布,也就说明,相邻第一电极条202之间具有第一缝隙S1,此第一缝隙S1呈半开放状。
第二电极部21包括在第一方向Y上延伸的第二连接条211以及在第一方向Y上间隔排布的多个第二电极条212,第二连接条211位于第一侧远离第二侧的位置,第二连接条211具有在第二方向X上相对的第三侧和第四侧,第三侧位于第四侧靠近第一侧的位置,需要说明的是,第二方向X与第一方向Y相互垂直;多个第二电极条212位于第二连接条211的第三侧并与第二连接条211连接,且相邻第二电极条212的远离第二连接条211的端部之间呈开口状,也就是说,相邻第二电极条212的远离第二连接条211的端部之间无连接。
需要说明的是,前述提到多个第二电极条212在第一方向Y上间隔排布,也就说明,相邻第二电极条212之间具有第二缝隙S2,此第二缝隙S2呈半开放状。
导电连接部22位于第一电极部20与第二电极部21之间,导电连接部22的两端分别与第一连接条201和第二连接条211连接。
在本公开的实施例中,通过将电极结构的第一电极部20和第二电极部21分别设计有呈半开放式的第一缝隙S1和第二缝隙S2,使得第一缝隙S1和第二缝隙S2开口处也可发生液晶分子偏转;因此,相比于图1示出的缝隙周围呈闭合的电极结构,可提高电极结构周围的光效。此外,如图2所示,第一电极部20的第一缝隙S1和第二电极部21的第二缝隙S2中一者开口方向朝右,另一者开口方向朝左;即:第一电极部20的第一缝隙S1和第二电极部21的第二缝隙S2的开口朝向相反,这样可均衡电极结构在第二方向X的两侧(即:图2中的左右两侧)的光效,从而使得电极结构周边光效更加均衡,以提高显示效果。
可选地,第一电极部20、第二电极部21与导电连接部22在参考平面上的正投影相互重合,此处提到的重合指的是在误差允许的范围内完全重合,这样设计可降低电极结构的设计难度,从而利于阵列基板中多个电极结构的排,但不限于此,第一电极部20、第二电极部21与导电连接部22在参考平面上的正投影也可不重合,视具体情况而定。
需要说明的是,本公开提到的参考平面为与第一方向Y相垂直的平面。
其中,前述提到的第一电极条202和第二电极条212可相互平行,即:第一电极条202和第二电极条212的延伸方向相互平行,以均衡第一电极部20和第二电极部21处的光效。具体地,第一电极条202和第二电极条212的延伸方向可与第三方向Q相互平行,此第三方向Q与第一方向Y和第二方向X相交,也就是说,第三方向Q不与第一方向Y和第二方向X平行或共线,这样设计可减小色偏,以提高显示效果。
举例而言,第三方向Q与第二方向X之间所夹锐角可为5°至15°,比如:5°、7°、9°、11°、13°、15°等等。
可选地,第一电极条202的第一宽度可与第二电极条212的第一宽度相等;此外,第一缝隙S1的第一宽度可与第二缝隙S2的第一宽度相等,这样可进一步均衡第一电极部20和第二电极部21处的光效,以提高产品显示效果。
需要说明的是,本公开中提到的第一宽度指的是在第四方向P上的尺寸,此第四方向P与第三方向Q相互垂直。
其中,为了保证第一电极部20和第二电极部21处的液晶分子偏转良好,以提高第一电极部20和第二电极部21处的光效;第一电极条202的第一宽度、第一缝隙S1的第一宽度、第二电极条212的第一宽度及第二缝隙S2的第一宽度需满足一定的要求;即:第一缝隙S1的第一宽度与第一电极条202的第一宽度之比可为1至4,比如:1、1.5、2、2.5、3、3.5、4等等。
具体地,本公开实施例的第一电极条202和第二电极条212的第一宽度可为1.8μm至3μm,比如:1.8μm、2μm、2.2μm、2.4μm、2.6μm、2.8μm、3μm等等;第一缝隙S1和第二缝隙S2的第一宽度可为3μm至7μm,比如:3μm、3.5μm、4μm、4.5μm、5μm、5.5μm、6μm、6.5μm、7μm等等。
此外,为进一步均衡第一电极部20和第二电极部21处的光效,以提高产品显示效果;第一连接条201的第二宽度与第二连接条211的第二宽度可相等。其中,第一连接条201与第二连接条211的第二宽度可与第一电极条202和第二电极条212的第一宽度相等,但不限于此,也可略大于第一电极条202和第二电极条212的第一宽度,以在提高光效的同时,还可改善由于第一连接条201和第二连接条211的第一宽度过小而导致其容易断线的情况,提高了产品良率。
需要说明的是,本公开实施例提到的第二宽度为在第二方向X上的尺寸。
其中,前述提到电极结构的第一电极部20和第二电极部21通过导电连接部22连接,为了避免在制造过程中导电连接部22受到Partical(杂质颗粒)影响而发生断线的情况,本公开实施例中将导电连接部22的面积设计的较大,以避免其极易形成断线而导致像素失效的情况,具体地,本公开实施例的导电连接部22的面积大于第一电极条202的面积和第二电极条212的面积。
应当理解的是,此导电连接部22整体的延伸方向也可与第三方向相互平行,以降低加工设计难度。举例而言,当导电连接部22在参考平面上的正投影与第一电极部20和第二电极部21在参考平面上的正投影重合时,为了使得导电连接部22的面积大于第一电极条202和第二电极条212的面积,本实施例可使第一电极条202的第一宽度和第二电极条212的第一宽度小于导电连接部22整体的第一宽度。
在本公开的一实施例中,如图3所示,导电连接部22可包括第一导电连接条221、第二导电连接条222及至少两条第三导电连接条223;其中,第一导电连接条221和第二导电连接条222均在第一方向Y上延伸,且第一导电连接条221和第二导电连接条222在第二方向X上间隔排布,第一导电连接条221与第一连接条201连接,第二导电连接条222与第二连接条211连接;至少两条第三导电连接条223在第一方向Y上间隔排布,并位于第一导电连接条221和第二导电连接条222之间,且各第三导电连接条223的两端(即:在其延伸方向上的两端)分别与第一导电连接条221和第二导电连接条222连接,也就是说,相邻第三导电连接条223之间具有为第三缝隙S3,且此第三缝隙S3四周闭合。
本公开实施例中,通过在导电连接部22内部进行开缝(即:第三缝隙S3)设计,一方面可减小导电连接部22上方的光效损失,从而可提高电极结构整体光效,另一方面,可以使得第一电极部20和第二电极部21通过至少两条导线(即:第三导电连接条223)连接导通,这样即使Partical导致其中一条导线断开,仍有其他导线连接导通第一电极部20和第二电极部21,从而可大大降低了像素失效的发生率,即:提高了产品良率。
可选地,第三导电连接条223设置两条,在保证第一电极部20和第二电极部21连接导通稳定的同时,还可适当减小导电连接部22在电极结构中的占比,即:为第一电极部20和第二电极部21提供更多的设计空间,换言之,第一电极部20和第二电极部21的面积可大于导电连接部22的面积,由于第一电极部20和第二电极部21的缝隙呈半开放设计,而导电连接部22的缝隙为封闭式设计,因此,第一电极部20和第二电极部21处的光效优于导电连接部22处的光效;这样通过使第一电极部20和第二电极部21的面积大于导电连接部22的面积,可提高电极结构整体的光效,提高产品质量。此外,由于开设第三缝隙S3,还可缓解在制作过程中Partical落到导电连接部22上的情况,从而可缓解导电连接部22的阻值因Partical增加的情况,继而缓解对像素的驱动产生的影响。
但应当理解的是,第三导电连接条223不限于设置两条,也可设置为三条、四条等,视具体情况而定。
其中,为了进一步减小导电连接部22在电极结构中的占比,第一导电连接条221的长度和第二导电连接条222的长度均小于第一连接条201的长度以及小于第二连接条211的长度。应当理解的是,此处提到的长度为在第一方向Y上的尺寸。
可选地,第一导电连接条221的第二宽度与第一连接条201的第二宽度可相等,第二导电连接条222的第二宽度与第二连接条211的第二宽度可相等。
在本公开的实施例中,第三导电连接条223的延伸方向与第三方向Q相互平行。其中,第三导电连接条223的第一宽度可与第一电极条202的第一宽度相等;此外,且相邻第三导电连接条223之间的第三缝隙S3可与相邻第一电极条202之间的第一缝隙S1、相邻第二电极条212之间的第二缝隙S2的相等,这样可均衡导电连接部22与第一电极部20和第二电极部21处的光效,以提高产品显示效果。
进一步地,第三导电连接条223与第一电极条202之间的第四缝隙S4、第三导电连接条223与第二电极条212之间的第五缝隙S5与前述提到的第一缝隙S1、第二缝隙S2、第三缝隙S3均相等,以均衡导电连接部22、第一电极部20、第二电极部21处以及三者之间处的光效,从而可提高产品显示效果。
在本公开的另一实施例中,如图2所示,导电连接部22可为一条导电连接条,此导电连接条在第三方向Q上延伸,其中,导电连接条的第一宽度与第一电极条202的第一宽度之比可为1.5至5.5,也就是说,导电连接部22相比于第一电极条202进行了加宽处理,以改善导电连接部22容易断线的情况,保证产品质量。
举例而言,在导电连接部22仅为一条导电连接条时,此导电连接条的第一宽度可为5μm至10μm,比如:5μm、6μm、7μm、8μm、9μm、10μm等等。
在本公开的一实施例中,如图2和图3所示,第一电极部20还包括信号连接条203,位于第一连接条201的第一侧并与第一连接条201连接,且位于多个第一电极条202远离导电连接部22的一侧。举例而言,在本公开的电极结构为公共电极时,此信号连接条203可与阵列基板中的公共线连接,也就是说,此信号连接条203处可用于接收公共信号;但不限于此,在本公开的电极结构为像素电极时,此信号连接条203还可与阵列基板中的晶体管的源漏电极连接,用于接收来自源漏电极传递过来的信号,例如:数据信号。
需要说明的是,图2和图3中虚线不具有实际意义,仅仅是为了将前述提到的各结构进行区分,以方便理解前述提到的各结构之间的位置关系,应当理解的是,本公开实施例提到的电极结构整体为一体式结构。
本公开还提供了一种显示面板,此显示面板可为液晶显示面板;如图4所示,显示面板可包括阵列基板3、与阵列基板3对盒设置的对置基板4以及位于对置基板4与阵列基板3之间的液晶分子5和多个隔垫物6;多个隔垫物6设置可以提高显示面板整体厚度的均一性,提高显示面板对液晶分子波动的容忍度,进而提高显示面板的良率。
举例而言,液晶分子5可为负性液晶分子,但不限于此,也可为正性液晶分子。多个隔垫物6中可包括主隔垫物和辅隔垫物,该主隔垫物在显示面板未收到外界压力时,其两端可分别与阵列基板3和对置基板4相接触,主要起到支撑作用;而辅隔垫物在显示面板未收到外界压力时,辅隔垫物若形成在对置基板4上,该辅隔垫物与阵列基板1之间具有一定的间距,也就是说,主隔垫物与辅隔垫物之间存在段差(高度差),通过调节主隔垫物与辅隔垫物之间的段差可以对显示面板的厚度进行微调。示例地,主隔垫物的高度大于辅隔垫物的高度,当显示面板受到外界压力时,主隔垫物先承受所有压力并压缩,当主隔垫物压缩至主隔垫物与辅隔垫物之间的段差降为0时,主隔垫物和辅隔垫物共同承受外界压力。
需要说明的是,主隔垫物和辅隔垫物这两种可按照一定周期排布。工艺制作过程中需要对不同种类隔垫物的尺寸高度进行监控。因隔垫物尺寸较小,且主隔垫物一般较少,单独依靠尺寸,设备很难准确识别主隔垫物位置,通常将主隔垫物周围某个位置空缺隔垫物设计(即:不设置任何隔垫物),以方便更快更准确的识别主隔垫物位置对其进行监控,例如:在设计时将主隔垫物下方不设置任何隔垫物,在监控时,可先快速确定不设置任何隔垫物的位置,然后前述提到的设计规则,可明确不设置任何隔垫物的上方位置处的隔垫物即为主隔垫物。
在本公开的实施例中,阵列基板3可包括第一衬底30及形成在第一衬底30上的多个子像素单元、多行扫描线31、多行公共线32、多列数据线33,其中:
如图5所示,第一衬底30可具有沿行方向X和列方向Y呈阵列排布的多个子像素区301、位于相邻两行子像素区301之间的第一布线区302以及位于相邻两列之间的第二布线区303,第一布线区302与第二布线区303之间存在交叠。举例而言,此第一衬 底30可为单层结构,该第一衬底30的材料可为玻璃。但不限于此,此第一衬底30还可多层结构;且第一衬底30的材料不限于玻璃,也可为其他材料,例如:聚酰亚胺(PI)等材料,视具体情况而定。
多个子像素单元形成在第一衬底30上,每个子像素单元包括至少部分位于子像素区301内的像素电极34、公共电极35以及至少部分位于第一布线区302的晶体管36。此外,子像素单元中还可包括电容器(图中未示出)。
在本公开的实施例中,如图6所示,晶体管36可包括有源层360、栅极361及同层设置的第一极362和第二极363;其中,栅极361与有源层360之间还可设置绝缘层37,以使栅极361与有源层360之间相互绝缘,此绝缘层37可采用无机材料制作而成,例如,氧化硅、氮化硅等无机材料。需要说明的是,栅极361可与扫描线31同层设置,栅极361可属于前述提到的扫描线31的一部分。
其中,晶体管36可为顶栅型,也可为底栅型。在本公开的实施例中主要以晶体管36为底栅型为例进行说明。在晶体管36为底栅型时,栅极361形成在第一衬底30上,此栅极361可包括金属材料或者合金材料,例如包括钼、铝及钛等,以保证其良好的导电性能;绝缘层形成在第一衬底30上并覆盖栅极361,此绝缘层可采用无机材料制作而成,例如:氧化硅、氮化硅等无机材料;有源层360形成在绝缘层背离第一衬底30的一侧,第一极362和第二极363分别与有源层360的两掺杂区连接,第一极362和第二极363可包括金属材料或者合金材料,例如由钼、铝及钛等形成的金属单层或多层结构,例如,该多层结构为多金属层叠层,例如钛、铝、钛三层金属叠层(Al/Ti/Al)等。
应当理解的是,子像素单元中晶体管36的数量可设置有多个,此晶体管36还分为N型和P型等。
在本公开的实施例中,像素电极34可与第一极362连接;其中,在与像素电极34连接的晶体管36为N型时,晶体管36的第一极362可为漏电极,第二极363可为源电极;在与像素电极34连接的晶体管36为P型时,晶体管36的第一极362可为源电极,第二极363可为漏电极。公共电极35在第一衬底30上的正投影与像素电极34在第一衬底30上的正投影存在交叠。其中,像素电极34和公共电极35中的至少一者为前述任一实施例所描述的电极结构,从而可提高像素周边光效,提高产品质量。需要说明的是,本实施例中提到的行方向X可为前述提到的第二方向X平行,而列方向Y可为前述提到的第一方向Y。
在本公开的实施例中,像素电极34可位于公共电极35靠近第一衬底30的一侧,也就是说,像素电极34可先于公共电极35制作在第一衬底30上;举例而言,此像素电极34可为板状电极;即:像素电极34为一整块并未开设狭缝;而公共电极35可为前述任一实施例所描述的电极结构;通过像素电极34和公共电极35之间产生的电场,使在电极之间和电极正上方的所有液晶分子发生偏转,可提高液晶的工作效率,且增加了透光效率。但不限于此,也可像素电极34位于公共电极35远离第一衬底30的一侧,此像素电极34为前述任一实施例所描述的电极结构;公共电极35为板状电极。
需要说明的是,本公开实施例主要以像素电极34位于公共电极35靠近第一衬底30的一侧,且像素电极34可为板状电极;而公共电极35可为前述任一实施例所描述的电极结构为例进行说明。
其中,为了保证阵列基板的透光率,像素电极34可采用ITO材料制作而成,但不限于此,也可采用氧化铟锌(IZO)、氧化锌(ZnO)等透明材料制作而成;也就是说,由于像素电极34采用的材料与晶体管36的栅极361、第一极362和第二极363的材料不同,因此,该像素电极34与晶体管36的栅极361、第一极362和第二极363可采用不同构图工艺制作而成。
举例而言,像素电极34可位于晶体管36的第一极362和第二极363靠近第一衬底 30的一侧,如图5所示,像素电极34可通过第二过孔结构H2与晶体管36的第一极362连接。其中,像素电极34可在形成晶体管36的栅极361之前形成在第一衬底30上,也就是说,在制作阵列基板时,可先采用一构图工艺在第一衬底30上形成像素电极34,然后再采用另一构图工艺在第一衬底30上形成晶体管36的栅极361。需要说明的是,像素电极34与栅极361虽然都形成在第一衬底30上,但像素电极34与栅极361之间相互断开(即:无连接)。但不限于此,像素电极34还可在形成晶体管36的栅极361之后形成在第一衬底30上,且此像素电极34还可位于栅极361远离第一衬底30的一侧。
同理,为了保证阵列基板的透光率,公共电极35也可采用ITO等透明导电材料制作而成;此公共电极35可形成在晶体管36的第一极362和第二极363远离第一衬底30的一侧,应当理解的是,此公共电极35和晶体管36的第一极362和第二极363之间还具有一层绝缘层。
至少一行扫描线31可位于一第一布线区302内,换言之,每一第一布线区302内可设置有至少一行扫描线31;其中,扫描线31与子像素单元中晶体管36的栅极361连接,前述提到扫描线31可与晶体管36的栅极361同层设置且为一体式结构,此扫描线31被配置为向子像素单元提供扫描信号。
至少一行公共线32可位于一第一布线区302内,换言之,每一第一布线区302内可设置有至少一行公共线32;其中,公共线32与公共电极35连接,其被配置为向子像素单元提供公共信号;举例而言,公共线32可与扫描线31同层设置,也就是说,公共线32可位于公共电极35靠近第一衬底30的一侧,如图5所示,此公共线32可通过第一过孔结构H1与公共电极35连接;具体地,公共线32可通过第一过孔结构H1与公共电极35的信号连接条连接;应当理解的是,此信号连接条可位于第一布线区302内。
在本公开的实施例中,如图7所示,公共线32具有位于第二布线区303之外且位于第一布线区302之内的第一段320,此第一段320在行方向X上可间隔排布并通过第二段321连接,此第二段321的部分位于第二布线区303,另一部位于第一布线区302。
具体地,如图7所示,公共线32的第一段320可具有在行方向X上依次排布的第一部3201、第二部3202及第三部3203,此第三部3203远离扫描线31的一侧比第一部3201远离扫描线31的一侧更远离扫描线31,第二部3202远离扫描线31的一侧比第一部3201远离扫描线31的一侧更靠近扫描线31,且第二部3202远离扫描线31的一侧与第一部3201和第三部3203之间形成有缺口a;也就是说,在第一段320靠近扫描线31的一侧为在行方向X上延伸的直线时,第三部3203在列方向Y上的尺寸大于第一部3201在列方向Y上的尺寸,即:第三部3203相比于第一部3201凸出设置;而第二部3202在列方向Y上的尺寸小于第一部3201在列方向Y上的尺寸,此第二部3202相比于第一部3201和第三部3203内缩设置,因此,第一部3201、第二部3202及第三部3203之间可形成有一缺口a;也就是说,公共线32不是平直的,既有缺口a,又有凸出的部分。
其中,如图7所示,第一过孔结构H1在第一衬底30上的正投影的部分与第二部3202和第三部3203在第一衬底30上的正投影存在交叠,另一部分与缺口a在第一衬底30上的正投影存在交叠,此关系可理解为公共线32处的第一过孔结构H1为半过孔设计,即:第一过孔结构H1的一部分正投影在公共线32上,另一部分投影在缺口a处,这样设计在保证第一过孔结构H1位于公共线32上的同时,还可改善取向层PI扩散均一性。
进一步地,第一过孔结构H1的边界线与第三部3203的边界线在列方向Y上的间距为第三间距,第一过孔结构H1的边界线与第三部3203中远离第二部3202的边界线在行方向X上的间距为第四间距,第一过孔结构H1的边界线与第二部3202中远离第三部3203的边界线在行方向X上的间距为第五间距,其中,为了确保第一过孔结构H1可以形成在公共线32上,前述提到的第三间距、第四间距及第五间距与第一电极条202的第一宽度之比可为1至6,比如:1、2、3、4、5、6等等,举例而言,第三间距、第四间 距及第五间距可为3μm至10μm,比如:3μm、5μm、7μm、10μm等等。
举例而言,如图5所示,每一第一布线区302内可设置有一行扫描线31和一行公共线32,应当理解的是,此扫描线31与公共线32之间相互断开,即:扫描线31在第一衬底30上的正投影与公共线32在第一衬底30上行的正投影不交叠。需要说明的是,第一布线区302内不限于设置一行扫描线31和一行公共线32,也可设置两行扫描线31,或不设置公共线32等等,视具体情况而定。本公开实施例主要以每一第一布线区302内设置有一行扫描线31和一行公共线32进行说明。
至少一列数据线33可位于一第二布线区303内,换言之,每一第二布线区303内设置至少一列数据线33,此数据线33可与子像素单元中晶体管36的第二极363连接,其被配置为向子像素单元提供数据信号。其中,数据线33在第一衬底30上的正投影与扫描线31和公共线32在第一衬底30上的正投影存在交叠。需要说明的是,本公开实施例的数据线33可与子像素单元中晶体管36的第一极362和第二极363同层设置,即:可采用同一构图工艺制作而成,以降低掩膜成本;但不限于此,也可采用不同构图工艺制作而成,视具体情况而定。
举例而言,如图5所示,每一第二布线区303内可设置一列数据线33,此数据线33可与同一列中各子像素单元的第二极363连接,也就是说,数据线33可为同一列子像素单元提供数据信号。
其中,每列数据线33可关于其中轴线呈对称设置,需要说明的是,此处提到的中轴线为经过数据线33的中心并在列方向Y上延伸的线。
可选地,位于数据线33在行方向X上相对两侧且相邻的两个第一极362与数据线33在行方向X上的间距可相等,以保证数据线33与两侧晶体管36耦合电容接近一致,从而保证数据线33两侧光效均一性。
同理,位于数据线33在行方向X上相对两侧且相邻的像素电极34可关于数据线33呈对称设置,位于数据线33在行方向X上相对两侧且相邻的两个公共电极35关于数据线33呈对称设置,以保证数据线33与两侧的像素电极34和公共电极35耦合电容接近一致,从而保证数据线33两侧光效均一性。
可选地,在一列子像素单元中,各子像素单元的第一极362和与其相连的数据线33在行方向X上的间距相等,以保证每列中各子像素单元的晶体管36和数据线33之间的耦合电容接近一致,保证每列各子像素单元处的光效均一性。需要说明的是,在一列子像素单元中各子像素单元的第一极362和与其相连的数据线33在行方向X上的间距相等的同时,该列第一极362与栅极361交叠面积需要与其他列保持一致。
在本公开的一实施例中,如图8所示,至少部分列数据线33具有对位部330,此对位部330位于第一布线区302与第二布线区303的交叠区域,且对位部330在第一衬底30上的正投影与公共线32和扫描线31在第一衬底30上的正投影不重合;其中,如图9所示,每个隔垫物6在第一衬底30上的正投影位于一对位部330在第一衬底30上的正投影内,也就是说,隔垫物6在第一衬底30上的正投影的外轮廓位于对位部330在第一衬底30上的正投影的外轮廓的内侧,确保了隔垫物6支撑处的平坦度,以保证隔垫物6稳定地支撑在阵列基板上。
需要说明的是,对位部330周围扫描线31呈异性设计,此扫描线31图案尽肯能保持相对数据线33对称,以保证数据线33两侧光效均一性。
其中,数据线33中对位部330在行方向X上的最大尺寸大于其他部位在行方向X上的最大尺寸;在本公开的实施例中,通过将数据线33中对位部330在行方向X上的尺寸设计的较大,以确保隔垫物6支撑处的平坦度,通过将数据线33中除对位部330之外的其他部位在行方向X上的尺寸设计的较小,可提高像素开口率。
可选地,如图8和图9所示,对位部330在第一衬底30上的正投影位于同一第一布 线区302内的扫描线31和公共线32在第一衬底30上的正投影之间,这样设计使得隔垫物6投影的对位部330的上、下、左、右四个方向均有金属块存在,即:上方存在扫描线31与数据线33交叠的部分,下方存在公共线32与数据线33交叠的部分,而左、右方分别存在一晶体管36,也就是说,阵列基板3中与隔垫物6相对应的区域的厚度小于此区域上、下、左、右四个方向具有前述提到的金属块的区域的厚度,这样可限定隔垫物6的滑动距离,阻止隔垫物6向有效区滑动,以保证显示效果,应当理解的是,有效区指的是能正常发光的区域,此有效区位于子像素区301内。
其中,如图8和图9所示,数据线33与扫描线31在第一衬底30上的正投影存在交叠的部分可定义为第一交叠部331,与公共线32在所述第一衬底30上的正投影存在交叠的部分可定义为第二交叠部332;此第一交叠部331与对位部330在列方向Y上的间距可为第一间距,第二交叠部332与对位部330在列方向Y上的间距可为第二间距,此第一间距和第二间距与第一电极条202的第一宽度之比为1.5至17,比如:1.5、3、5、8、11、14、17等等;举例而言,此第一间距和第二间距可为5um至30um,比如:5um、10um、15um、20um、25um、30um等等,但不限于此,具体可根据阵列基板与对置基板实际对合精度、第一交叠部331所在区域、第二交叠部332所在区域对隔垫物6的阻挡作用、对DNU(Dark Not Uniformly,暗态不均匀)的影响而决定。
举例而言,本公开实施例中提到的对位部330在第一衬底30上的正投影形状可类似为菱形、椭圆形或六边形等,视具体情况而定。需要说明的是,阵列基板中对位部330设置的数量和位置可与隔垫物6的数量和位置相匹配,即:对位部330与隔垫物6一一对应。
在本公开的一实施例中,对置基板可包括位于隔垫物6远离阵列基板3一侧的第二衬底(图中未标示出)及位于第二衬底靠近阵列基板3一侧的遮挡层40,此遮挡层40具有交叉遮挡部401、位于交叉遮挡部401在行方向X相对两侧的第一遮挡部402、以及位于交叉遮挡部401在列方向Y上相对两侧的第二遮挡部403;需要说明的是,交叉遮挡部401在第一衬底30上的正投影至少覆盖第一布线区302与第二布线区303的交叠区域,而第一遮挡部402在第一衬底30上的正投影至少覆盖第一布线区302且位于与第二布线区303之外,第二遮挡部403在第一衬底30上的正投影至少覆盖第二布线区303且位于第一布线区302之外。
其中,结合图10和图11所示,遮挡层40中第一遮挡部402、第二遮挡部403和交叉遮挡部401可呈阵列排布,阵列排布的第一遮挡部402、第二遮挡部403和交叉遮挡部401可围成透光孔404,此透光孔404在第一衬底30上的正投影位于子像素区301内,该透光孔404用于允许光线透过。在整个显示面板的面积一定时,透光孔404的面积总和越大,也就是说,遮挡部的面积总和越小,则显示面板的光透过率越高,显示效果越好。应当理解的是,图11中虚线均不具有实际含义,仅仅是为了方便本领域技术人员理解遮挡层22中各部分。
需要说明的是,为了保证遮挡层40能够将阵列基板3上布线区完全遮盖,可使遮挡层40中第一遮挡部402、第二遮挡部403和交叉遮挡部401在第一衬底30上的正投影还可覆盖部分子像素区301。
在本公开的实施例中,当显示面板受到较大外力时,尤其是跌落测试等冲击力较大时,隔垫物6主要表现为在列方向Y滑动,因采用隔垫物6在数据线33的对位部330上这一设计,隔垫物6滑动始终在数据线33上方,由于数据线33的支撑作用,隔垫物6不会划伤有效区,此外,因数据线33上方有第二遮挡部403和交叉遮挡部401进行遮挡,即使数据线33上方的膜层(即:取向膜层)出现划伤而导致漏光,也会被第二遮挡部403和交叉遮挡部401遮挡住,不会形成点状或大面积的暗态漏光不良,继而可提高显示效果。
此外,即使隔垫物6在受到压力时表现为在行方向X上滑动,由于第一布线区302上方有第一遮挡部402和交叉遮挡部401进行遮挡,也不会形成点状或大面积的暗态漏光不良,继而可提高显示效果。
在本公开的一实施例中,如图10和图11所示,交叉遮挡部401在列方向Y上的最大尺寸可大于第一遮挡部402在列方向Y上的最大尺寸,且交叉遮挡部401在行方向X上的最大尺寸大于第二遮挡部403在行方向X上的最大尺寸,这样设计可避免隔垫物6在压力测试过程中滑出遮挡区域,从而可改善暗态漏光不良的问题。
应当理解的是,在本公开实施中,如图10和图11所示,不限于所有的交叉遮挡部401在列方向Y上的最大尺寸大于第一遮挡部402在列方向Y上的最大尺寸、在行方向X上的最大尺寸大于第二遮挡部403在行方向X上的最大尺寸;可仅使与隔垫物6对应的交叉遮挡部401这样设计,而其他未与隔垫物6对应的交叉遮挡部401在列方向Y上的尺寸可与第一遮挡部402在列方向Y上的尺寸相等,在行方向X上的尺寸可与第二遮挡部403在行方向X上的尺寸相等,这样可提高像素开口率。
举例而言,如图11所示,与隔垫物6对应的交叉遮挡部401可近似为六边形,未与隔垫物6对应的交叉遮挡部401、第一遮挡部402和第二遮挡部403可近似为矩形,但不限于此,也可为其他形状,视具体情况而定。
其中,隔垫物6在第二衬底上的正投影可位于交叉遮挡部401在第二衬底上的正投影的中心区域内,且隔垫物6在第二衬底上的正投影的边缘与交叉遮挡部401在第二衬底上的正投影的边缘之间的间距为第六间距,此第六间距与第一电极条202的第一宽度之比为11至33,比如:11、17、23、28、33等等;举例而言,第六间距可为35μm至60μm,比如:35μm、40μm、45μm、50μm、55μm、60μm等等;这样设计可避免隔垫物6在压力测试过程中滑出遮挡区域,从而可改善暗态漏光不良的问题。
在本公开的实施例中,遮挡层40除了覆盖数据线33、公共线32、扫描线31、晶体管36和部分公共电极35之外,还可覆盖部分像素电极34。其中,像素电极34边缘靠近扫描线31、数据线33区域存在耦合电场,显示过程中会导致液晶排布紊乱,产生失效区,导致暗态像素边缘漏光,因此需要遮挡层40对这部分失效区进行遮挡。
其中,前述提到的子像素单元的晶体管36在第一衬底30上的正投影可位于第一遮挡部402在第一衬底30上的正投影内,其中,子像素单元的像素电极34具有第一失效区,此第一失效区与第二极363通过第二过孔结构H2连接;其中,第一失效区在第一衬底30上的正投影位于第一遮挡部402在第一衬底30上的正投影内,此第一失效区在列方向Y上的尺寸与第一电极条202的第一宽度之比为1.5至5.5;比如:1.5、2.5、3.5、4.5、5.5等等,举例而言,第一失效区在列方向Y上的尺寸可为5μm至10μm,比如:5μm、6μm、7μm、8μm、9μm、10μm等等,也就是说,第一遮挡部402覆盖像素电极34至少5um,需要说明的是,在彩膜层位于对置基板上时,考虑上下基板对盒精度,需加宽更多,但也不得超过10μm,以避免过多影响像素开口率。
此外,数据线33与像素电极34边缘同样存在耦合电场,也就是说,本公开实施例的像素电极34还具有第二失效区,此第二失效区在第一衬底30上的正投影可位于第二遮挡部403在第一衬底30上的正投影内;其中,在液晶分子5为负性液晶分子,该电场不会导致液晶旋转,第二失效区在行方向X上的尺寸与第一电极条202的第一宽度之比为0.3至0.5,比如:0.3、0.4、0.5等等,举例而言,第二失效区在行方向X上的尺寸可为1μm作用,也就是说,第二遮挡部403的覆盖像素电极341μm左右,以遮挡数据线33附近的Shadow(阴暗)区。若在液晶分子5为正性液晶分子时,数据线33与像素电极34之间的耦合电场不会导致明显的暗态漏光,但是会导致液晶分子造成Crosstalk(串扰)现象加重,因此,此时,像素电极34的第二失效区在行方向X上的尺寸与第一电极条202的第一宽度之比可为2至5.5,比如:2、2.5、3、3.5、4、4.5、5、5.5等等, 举例而言,第二失效区在行方向X上的尺寸可为6μm至10μm,比如:6μm、7μm、8μm、9μm、10μm等等,也就是说,第二遮挡部403的覆盖像素电极34至少6um,以遮挡耦合电场区域。
需要说明的是,液晶显示面板中用到的彩膜层可位于对置基板4上,也可位于阵列基板3上,视具体情况而定。

需要说明的是,本文中所述的“在……上”、“在……上形成”和“设置在……上”可以表示一层直接形成或设置在另一层上,也可以表示一层间接形成或设置在另一层上,即两层之间还存在其它的层。
用语“一个”、“一”、“该”、“所述”和“至少一个”用以表示存在一个或多个要素/组成部分/等;用语“包括”和“具有”用以表示开放式的包括在内的意思并且是指除了列出的要素/组成部分/等之外还可存在另外的要素/组成部分/等。
需要说明的是,虽然术语“第一”、“第二”等可以在此用于描述各种部件、构件、元件、区域、层和/或部分,但是这些部件、构件、元件、区域、层和/或部分不应受到这些术语限制。而是,这些术语用于将一个部件、构件、元件、区域、层和/或部分与另一个相区分。
在本公开中,除非另有说明,所采用的术语“同层设置”指的是两个层、部件、构件、元件或部分可以通过同一构图工艺形成,并且,这两个层、部件、构件、元件或部分一般由相同的材料形成。
在本公开中,除非另有说明,表述“构图工艺”一般包括光刻胶的涂布、曝光、显影、刻蚀、光刻胶的剥离等步骤。表述“一次构图工艺”意指使用一块掩模板形成图案化的层、部件、构件等的工艺。
