Description

一种基板、显示面板及显示装置
【技术领域】
本发明涉及显示领域，特别是涉及一种基板、显示面板及显示装置。
【背景技术】
在现有的显示器中，使用较为广泛的是液晶显示器（Liquid Crystal Display，简称LCD），特别是薄膜晶体管（Thin Film Transistor简称TFT）型液晶显示器（简称TFT-LCD）。请参阅图1，一般，TFT-LCD包括彩色滤光基板110、阵列基板120及液晶130。彩色滤光基板110包括基板玻璃111、色阻层112以及铟锡氧化物薄膜（Indium Tin Oxides，简写ITO）113，阵列基板120包括多条扫描线121和数据线122，以及与扫描线121及数据线122连接的多个TFT 123。液晶130夹置在彩色滤光基板110与阵列基板之间，TFT-LCD通过扫描线121和数据线122向TFT 123提供电信号，TFT123与彩色滤光基板110的ITO 113间形成电场，以驱动液晶130，实现显示。
本申请发明人发现，因扫描线121或数据线122而产生的电容会造成扫描线121或数据线122的信号出现延迟。当扫描线121或数据线122产生的电容较大时，扫描线121或数据线122的信号延迟也随着严重，此时，可能会造成TFT-LCD出现亮度不均（mura）等显示不良现象。
本申请发明人还发现，在现有TFT-LCD中，扫描线121和/或数据线122与ITO 113之间形成的电容是扫描线121和/或数据线122产生的电容主要原因。TFT-LCD进行工作时，由于阵列基板120的扫描线121和数据线122的电信号是变化的，当扫描线121和/或数据线122与处于其上方部分的ITO 113电位不同时，则会使得扫描线121和/或数据线122与ITO 113形成电容，产生负载，进而造成信号延迟。

【具体实施方式】
下面结合附图和具体的实施方式进行说明。
请参阅图2和图3，图2是本发明显示面板一实施方式的结构示意图，图3是图2所示的显示面板的第二基板的局部结构示意图。本实施方式中，显示面板包括相对设置的第一基板210、第二基板220，以及夹置于第一基板210和第二基板220之间的液晶230。
第二基板220设有行列设置的扫描线221和数据线222（图2中为简洁目的而示意性地仅画出一条扫描线和一条数据线，并且为方便看到扫描线和数据线，示意性地画出同向设置的数据线和扫描线，但实际上数据线和扫描线是行列设置的（如图3），前述的图1、以及下面本申请图4、图5也同理），以及设置于扫描线221和数据线222之外的剩余区域223上的多个薄膜场效应晶体（Thin Film Transistor，简称TFT）224和多个电极225，所述多个薄膜场效应晶体224的三个管脚分别与相应的扫描线221、数据线222、以及电极225连接。第二基板220相应的扫描线221和数据线222通过向与之连接的薄膜场效应晶体224输入相应的信号，实现控制与所述薄膜场效应晶体224连接的电极225的电位。
第一基板210至少分为第一区域211和第二区域212。其中，第一基板210的第一区域211相对第二基板220上的扫描线221以及数据线222设置，第一基板210的第一区域211的材料为绝缘材料，与第二基板220的扫描线221和数据线222间构成无电容结构，即第一基板210中与扫描线221和数据线222正相对的第一区域211不会导致第一区域211与扫描线221和/或数据线222之间形成电容。
所述第一基板210的第二区域212相对第二基板220上的扫描线221和数据线222之外的剩余区域223设置，第二区域212至少部分为导电结构，所述导电结构与第二基板220的电极225之间可形成电场。第二基板220通过扫描线221和数据线222控制电极225的电位，以使所述第二基板220的电极225与第一基板210的第二区域220的导电结构之间形成相应的电场，进而驱动液晶实现显示。由于液晶显示方面不是本发明重点，且液晶显示驱动原理为现有技术，故对本发明显示面板具体如何实现显示不作具体描述，如有需要，请参考液晶显示的相关资料。
现有技术中，由于第二基板的扫描线和数据线与第一基板之间形成的电容，与正对扫描线、数据线的第一基板部分是否存在导电结构、以及若存在导电结构时该导电结构的面积大小、导电性能有关，因此在本申请中，本发明实施方式通过将第一基板210中与第二基板220的扫描线221和数据线222正相对的第一区域211设置为绝缘结构，使得正对扫描线211和数据线222的第一区域211与扫描线221和数据线222之间不会形成电容，或即使形成电容但其电容较小，进而降低扫描线221和数据线222信号的延迟效应。同时，由于第二基板220上的扫描线221和数据线222所占的区域较小，即对应第一基板210的第一区域211绝缘结构也较小，故对液晶230的驱动不会产生较大的影响。
需要说明的是，本发明中第一基板的第一区域并不限为绝缘结构，在其他实施方式中，第一基板的第一区域也可为部分绝缘结构，或者导电性较弱的导电结构，以使第一基板的第一区域与第二基板的扫描线和数据线间为低电容结构。进一步地，在其他具体实施方式中，第一基板的第一区域可设置成其他能够减少与扫描线、数据线间的电容的结构，例如第一区域与第二区域同为导电结构，第一基板的第一区域相对扫描线和数据线设置为凹形结构，以使第一区域与扫描线和数据线的距离较大，进而构成相对较低电容的结构。故本发明对第一基板的第一区域的具体结构不作限定。
另外，对本申请所述的低电容结构进行说明，所述低电容结构为：相对于现有显示面板中第二基板的扫描线、数据线与第一基板的ITO完全正对设置而形成的现有电容结构（如图1），使第二基板的扫描线、数据线与第一基板中与所述扫描线、数据线正相对于的第一区域之间形成的电容少于现有电容结构所形成的电容的结构。
请参阅图4，图4是本发明显示面板另一实施方式的结构示意图。本实施方式中，显示面板包括相对设置的第一基板410、第二基板420，以及夹置于第一基板410和第二基板420之间的液晶430。第二基板420与上一实施方式的第二基板结构相同，故不再赘述。第一基板410至少分为第一区域411和第二区域412。其中，第一基板410的第一区域411相对第二基板420上的扫描线421以及数据线422设置，第一基板410的第二区域412相对第二基板420上的扫描线421和数据线422之外的剩余区域423设置。
具体地，第一基板410包括依次层叠设置的玻璃基板413、色阻层414及导电薄膜415，其中，玻璃基板413设置在第一基板410远离第二基板420一侧，色阻层414和导电薄膜415均仅设置于第二区域412中，而第一区域411无设置色阻层414及导电薄膜415。第一基板410的第一区域411仅设置有玻璃基板413，第一区域411中的玻璃基板413与液晶430直接接触。由于玻璃基板413为绝缘机构，且第一区域411中的玻璃基板413与第二基板420的扫描线421、数据线422之间无设置导电机构，故第一区域411中的玻璃基板413与第二基板的扫描线421、数据线422之间不会形成电容，构成无电容结构。
同时，第一基板410的第二区域412的导电薄膜415与第二基板420中设置在扫描线421、数据线422之外的剩余区域的电极（图未示）之间可形成电场，进而保证实现液晶显示。本实施方式中，导电薄膜415为铟锡氧化物薄膜ITO 415。
在其他实施方式中，本发明第一基板的第一区域也可以部分设置有导电薄膜，第一基板的第一区域与第二基板的扫描线、数据线之间构成低电容结构，进而减少第二基板的扫描线和数据线产生的电容。
请参阅图5，图5是本发明显示面板再一实施方式的结构示意图。本实施方式中的显示面板与上一实施方式中的显示面板结构基本相同，其不同在于，本实施方式的第一基板510的色阻层514设置在第一基板510的第一区域511和第二区域512，第一区域511的色阻层514与夹置在第一基板510和第二基板520之间的液晶530直接接触。由于色阻层514为导电性低的机构，故第一基板510的第一区域511与第二基板520的扫描线521、数据线522之间构成低电容结构，以减少第二基板520的扫描线521和数据线522产生的电容。
需要说明的是，为便于描述，本申请所有实施方式中的第一区域均相对第二基板的扫描线以及数据线设置，但并不能认为本发明的第一区域仅限定为同时相对第二基板的扫描线以及数据线设置。在其他实际应用需要的实施方式中，所述第一基板的第一区域也可仅相对第二基板的扫描线或者数据线设置，以减少第二基板的扫描线或者数据线与第一基板间的电容，故在此不作限定。
此外，本申请举例的实施方式中显示面板为液晶显示面板，但本申请并不仅限为液晶显示面板，还可以是其他类型的矩阵显示面板，如等离子显示等，故在此不作限定。
再者，本申请图2至图5仅为便于描述本发明的简单的结构示意图。在实际应用中，本发明显示面板还可能包括图2至5未标示出来的结构，例如，第一、第二基板还可以包括配向膜，第二基板还包括玻璃基板等其他结构。同理地，如果第一基板包括的其他结构为导电结构，则所述导电结构仅设置在第二区域，使得第一区域不具有导电性，或者第一区域只部分设置有具有导电结构，以保证第一基板的第一区域与第二基板的扫描线、数据线之间为无电容结构或者低电容结构。
区别于现有技术，本发明通过将第一基板至少分为第一区域和/或第二区域，且所述相对第二基板上的扫描线和/或数据线设置的第一区域与第二基板上的扫描线和/或数据线之间为无电容结构或低电容结构，以减少第一基板第一区域与第二基板的扫描线和/或数据线间形成的电容，进而减少了第二基板的扫描线和/或数据线产生的电容，实现降低扫描线和/或数据线信号的延迟。
请参阅图6，图6是本发明显示装置一实施方式的结构示意图。本实施方式中，显示装置包括显示面板610和背光模组620，其中，显示面板为上述实施方式中的显示面板。其具体实施请参阅图2至图5以及上述实施方式，在此不再赘述。
当然，在其他实施方式中，显示装置未必包括背光模组，本发明显示装置为包括上述实施方式中的显示面板的任意装置。
本申请再提供一种基板的实施方式，所述基板至少分为第一区域和第二区域，所述基板的第一区域以相对构成显示面板的另一基板上的扫描线和数据线的方式设置，所述第二区域以相对所述另一基板上的扫描线和数据线之外的剩余区域的方式设置，所述第一区域均为绝缘结构。具体地，所述基板包括依次层叠设置玻璃基板、色阻层和导电薄膜。所述色阻层和导电薄膜仅设置于所述第二区域，而所述第一区域仅设置有所述玻璃基板。
在本发明基板另一实施方式中，所述基板即为上述实施方式中的显示面板中的第一基板，其具体实施请参阅图2至图5以及上述实施方式的相关文字说明，在此不再赘述。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
