Description

像素结构、液晶显示器和电子设备
本发明要求2015年9月22日递交的发明名称为“像素结构、液晶显示器和电子设备”的申请号201510608888.1的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及一种液晶显示器的像素结构，特别涉及一种具有高开口率的像素结构。
背景技术
随着电子科技的进步，尤其在日常生活中便携式电子产品的盛行，对于轻薄短小、耗电量低的显示器装置的需求与日俱增。液晶显示器(Liquid Crystal Display；LCD)装置由于具有低耗电、厚度薄、重量轻等优点，适用于此类的电子产品中，甚至已逐步取代传统的阴极射线管显示器装置。
液晶显示面板一般由彩色滤光(Color Filter，CF)基板和阵列(Array)基板组成，CF基板和Array基板的可透光区域占总显示区域的比例(即开口率)是影响液晶显示面板透过率的主要因素之一，开口率也是影响液晶显示器特性的重要因素，因此业界提出了各种像素结构以增加像素的开口率。而液晶显示面板透过率低会增加液晶显示面板的功耗、耗费液晶显示面板的制造成本。
像素层(Pixel Layer)一般为Array基板的最后一层，在液晶显示面板中起到直接控制电场、对液晶分子的排列施加影响的作用。Pixel Layer的设计往往对Panel的透过率等光学特性有重要影响。

由于trunk、数据线和遮光线均为不透光部分，使得显示时使得像素不透光面积比较小，开口率也相对较小，致使液晶显示面板的显示效率大打折扣。

下面将结合本发明实施例中的附图，对本发明实施例中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一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图2、图3，本发明所述的像素结构包括像素层200、数据线3和栅极线4，所述像素层200包括多个像素区域20(图2中虚线包围区域)。每像素区域20包括一个上区域21和一个下区域22。上区域21和下区域22中各自设有像素电极(未编号)，像素电极的龙骨23(trunk)分别设置上区域21的一个侧边和下区域22的一个侧边上，即上区域21与下区域22中各自包括 一条龙骨23。所述像素层200的下方设有多条数据线3和多条栅极线4，即所述像素层200和所述数据线3设置在不同层，所述像素区域20设置在所述多条数据线3和所述多条栅极线4交叉形成的区域上方。进一步的，所述数据线3在所述像素层200的投影与所述龙骨23重合，换而言之，所述龙骨23在所述数据线3所在层上的投影完全落入所述数据线3所围绕的区域内。
本发明中通过将龙骨覆盖在处于在不同层的数据线上面，由于所述龙骨和所述数据线皆为不透光材料，将二者重叠可以有效减少非显示区域的面积，提高开口率。此外，通过这种方法还可以省去在龙骨下方设置遮光线的步骤，进一步降低了生产的成本，提高了生产效率。
作为进一步优选的，每个所述像素区域中的所述两个龙骨23位于所述像素区域20的相对的两个侧边处，即所述上区域21和所述下区域22的龙骨23设置在不同侧。在本实施例中，所述上区域21的龙骨23设置在上区域21的左侧，所述下区域22的龙骨23设置在下区域22的右侧。也就是说上区域21和下区域22的电极朝向相反。
请接合参阅图3和图4，图4为是本发明像素结构的部分电路图。将上区域21和下区域22的龙骨23设置在不同侧的原因在于：本发明中，俯视角度看，位于上区域21左边和下区域22右边的龙骨23分别与其下方的一条数据线3重叠。数据线3与像素电极8之间存在耦合电容。具体的，位于上区域21左边的龙骨23相对应的左边数据线3与像素电极8之间的耦合电容为Cpd，如果此耦合电容过大，数据线3上电压的变化会引起像素电压的变化，从而引起画面抖动，垂直串扰(V-crosstalk)等显示问题。因为本发明中，像素区域右侧也会有数据线3分布，即下区域22右边的龙骨23相应的右边数据线3与像素电极8之间也会形成耦合电容Cpd’。在Column Inversion下，相邻的数据线23的极性相反，从而使得灰底白框下，数据线23电压切换由Cpd和Cpd’对像素的耦合作用可以相互抵消，从而可以改善灰底白框画面下Cpd耦合作用引起的V-crosstalk和画面抖动等问题。
进一步的，请继续参阅图3，相邻的两个像素区域20共用一条数据线3，数据线3由一个像素区域的上区域21的龙骨23下方向相邻像素区域的下区域22走线排布。换而言之，数据线3大致呈S形走线设计，使得原本设置在相邻像素区域的龙骨23下的遮光线6可以经由S形的数据线3代替，省去了龙骨23下方遮光线的使用，提高了像素结构的开口率。
更进一步的，请参阅图2、图3，所述像素结构还包括遮光线6，在每个像素区域20中，与所述龙骨23相对的一侧对应设有遮光区24，所述遮光线6与所述遮光区24重合，即在图2中上区域21的右侧下方和下区域22的左侧下方对应设有遮光线6，遮光线6用于遮挡相邻像素区域20的漏光。具体的，所述遮光线6设置在数据线3所在层的下一层，两者通过绝缘层(图未示出)进行隔开。
进一步的，在本发明中，为了了减轻数据线负载，所述的像素结构采用COA(Color Filter On Array)技术。COA结构的产品中，相邻的像素区域20之间会发生Overlay(交叠)，产生重叠部，重叠部亦称为牛角，牛角的存在使得周围液晶倒向混乱，产生暗纹，使得产品穿透率降低。本发明中，数据线3不与所述牛角重叠。同时，将数据线3设计成弯曲的S形绕开所述牛角，使得牛角与像素电极之间存在一定距离，从而避免牛角周围液晶倒向混乱而产生像素暗纹。此外，数据线3不与所述牛角重叠还可以使得牛角处的高度不至于过高，有利于从整体上减小像素结构的体积，节省占用的空间。
进一步的，所述牛角应该设置在遮光线6的上方，换而言之，所述遮光线6在所述像素层200上的投影与所述重叠部重合，通过将牛角与所述遮光线对应设置，通过遮光线6为所述重叠部进行遮光，可以进一步提高所述像素结构的开口率。
在本发明的其他实施例中，还可以将同一像素区域20的上区域21和下区域22中的龙骨23设置在相同的一侧，也就是说，此时上区域21和下区域22的像素电极朝向相同。相应的，遮光线6设置在像素区域20中与所述龙骨23 相对的一侧的下方。在本实施例中，数据线3可以设置成直线，并对应设置在龙骨23的下方，同样起到了提升开口率的作用。但是，这种设计中，数据线与像素电极之间会产生一个耦合电容Cpd，如果此耦合电容过大，数据线上电压的变化会引起像素电压的变化，从而引起画面抖动，V-crosstalk等显示问题，所以对于这种设计下，像素层200上方需要设置一信号屏蔽层。其中，信号屏蔽层可以是透明导电层，能够作为一个导体，耦合掉数据线与像素电极之间会产生的耦合电容Cpd。在实际的像素结构中，该透明导电层通过绝缘层与像素层200之间进行绝缘。
当然，在实际应用中，只需要在像素层200与其最接近的数据线或者栅极线之间设置一信号屏蔽层即可保证像素层200上的电场不受到干扰。换而言之，在现有的顶栅型像素结构中，栅极线往往要比数据线更接近像素层200，栅极线与像素电极之间会产生一个耦合电容Cpd，因此需要在栅线与像素层200之间设置一个信号屏蔽层。
以上介绍了本发明的一种像素结构，本发明还设计了一种采用上述像素结构的液晶显示器，
可以理解的是，本发明揭示的液晶显示器可以用在手机、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电子设备或部件中。
本发明还提供了一种采用上述液晶显示器的电子设备，所述液晶显示器与所述电子设备的本体电性连接。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
