Description

液晶显示面板及液晶显示装置
【技术领域】
本发明涉及显示技术领域，特别是涉及一种液晶显示面板及液晶显示装置。
【背景技术】
液晶显示面板包括TFT（Thin Film Transistor，薄膜场效应晶体管)基板以及CF（Color Filter，彩色滤光片）基板，其中，TFT基板上包括多条数据线和多条扫描线，并且数据线连接数据驱动芯片(Source driver IC)，扫描线连接扫描驱动芯片（Gate driver IC）。其中，数据驱动芯片和扫描驱动芯片之间通过设置在TFT基板上的阵列走线(Wire on array，WOA)线路实现信号传输。
CF基板上通常设置有与CF基板面积相等的整片的ITO（Indium-Tin Oxide，氧化铟锡）透明导电膜。
上述现有的结构导致在液晶显示面板的数据线和CF基板上的ITO透明导电膜之间形成电容结构，并且CF基板上的ITO透明导电膜和连接数据驱动芯片和扫描驱动芯片的WOA线路之间也存在寄生电容。因此，在液晶显示面板进行显示时，TFT基板中多条数据线同时输送信号，使得CF基板上的ITO透明导电膜的电位易于受数据线输送的信号的影响而产生波动。而CF基板上的ITO透明导电膜的电位变化又使得WOA线路的电位产生变动。由于驱动芯片会受WOA线路的电压影响，因此WOA线路的电位产生变动易于使驱动芯片产生误动作而导致画面显示异常。
【发明内容】
本发明主要解决的技术问题是提供一种液晶显示面板以及液晶显示装置，能够消除因阵列走线的电位波动而引起驱动芯片产生误动作的现象，从而提高了液晶显示面板的显示品质。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种液晶显示面板，其包括相对设置的阵列基板、彩色滤光片基板以及用于驱动液晶显示面板的数据驱动芯片和扫描驱动芯片，其中，数据驱动芯片和扫描驱动芯片之间通过设置在阵列基板上的阵列走线电连接，在阵列基板上，且位于阵列走线上方设置有接地的电场屏蔽层，其中，阵列走线和电场屏蔽层之间为绝缘层，数据驱动芯片的至少一个管脚与电场屏蔽层的一端连接，并且数据驱动芯片与电场屏蔽层连接的管脚接地。
其中，电场屏蔽层为ITO或IZO导电薄膜。
其中，电场屏蔽层和绝缘层设置的宽度大于或者等于阵列走线的宽度
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种液晶显示面板，其包括相对设置的阵列基板、彩色滤光片基板以及用于驱动液晶显示面板的数据驱动芯片和扫描驱动芯片，其中，数据驱动芯片和扫描驱动芯片之间通过设置在阵列基板上的阵列走线电连接，阵列走线与彩色滤光片基板之间进一步设置有接地的电场屏蔽层。
其中，电场屏蔽层设置在彩色滤光片基板上，且对应设置在阵列走线的上方，彩色滤光片基板和电场屏蔽层之间为绝缘层。
其中，电场屏蔽层设置在阵列基板上，且位于阵列走线上方，阵列走线和电场屏蔽层之间为绝缘层。
其中，数据驱动芯片的至少一个管脚与电场屏蔽层的一端连接，并且数据驱动芯片与电场屏蔽层连接的管脚接地。
其中，电场屏蔽层为ITO或IZO导电薄膜。
其中，电场屏蔽层和绝缘层设置的宽度大于或者等于阵列走线的宽度。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种液晶显示装置，其包括背光系统以及液晶显示面板，液晶显示面板包括相对设置的阵列基板、彩色滤光片基板以及用于驱动液晶显示面板的数据驱动芯片和扫描驱动芯片，其中，数据驱动芯片和扫描驱动芯片之间通过设置在阵列基板上的阵列走线电连接，阵列走线与彩色滤光片基板之间进一步设置有接地的电场屏蔽层。
其中，电场屏蔽层设置在彩色滤光片基板上，且对应设置在阵列走线的上方，彩色滤光片基板和电场屏蔽层之间为绝缘层。
其中，电场屏蔽层设置在阵列基板上，且位于阵列走线上方，阵列走线和电场屏蔽层之间为绝缘层。
其中，数据驱动芯片的至少一个管脚与电场屏蔽层的一端连接，并且数据驱动芯片与电场屏蔽层连接的管脚接地。
其中，电场屏蔽层为ITO或IZO导电薄膜。
其中，电场屏蔽层和绝缘层设置的宽度大于或者等于阵列走线的宽度。
本发明的有益效果是：区别于现有技术的情况，本发明通过在阵列走线与彩色滤光片基板之间设置接地的电场屏蔽层，因电场屏蔽层的电位恒定，消除彩色滤光片基板上的导电薄膜的电位波动对阵列走线的电位的影响，避免阵列走线的电位产生波动，从而避免驱动芯片的误动作，进而提高了液晶显示面板的显示品质。

图3是 是图1所示的液晶显示面板的电容分布示意图；
图4是 本发明一种液晶显示面板第二实施例的局部结构示意图；
图5是 本发明一种液晶显示装置的结构示意图。
【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
请参考图1，图1是本发明一种液晶显示面板第一实施例的局部结构示意图，如图1所示，本发明的液晶显示面板100包括阵列基板101、彩色滤光片基板102、数据驱动芯片103以及扫描驱动芯片104。
其中，阵列基板101和彩色滤光片基板102相对设置，数据驱动芯片103和扫描驱动芯片104用于驱动液晶显示面板100。其中，数据驱动芯片103连接多条数据线，如图1所示的S1、S2以及S3。数据驱动芯片103和扫描驱动芯片104之间通过设置在阵列基板101上的阵列走线105（WOA）电连接，以实现数据驱动芯片103和扫描驱动芯片104之间的信号传输。数据驱动芯片103通过阵列走线105向扫描驱动芯片104传输扫描驱动芯片104所需的控制信号、TFT开态电压Von或者TFT关态电压Voff等信号。
应理解，图1中仅示出一条阵列走线105作为举例说明，实际中，液晶显示面板100中包括多条阵列走线，例如，至少包括用于向扫描驱动芯片104传输控制信号的阵列走线、用于传输TFT开态电压Von的阵列走线以及用于传输TFT关态电压Voff的阵列走线。
本实施例中，在阵列走线105与彩色滤光片基板102之间进一步设置有接地的电场屏蔽层125，并且阵列走线105与电场屏蔽层125之间为绝缘层115。
具体而言，请参阅图2所示，图2为图1中阵列基板101沿着所示虚线AA＇的剖面结构示意图。
请参考图2，阵列基板101上设置阵列走线105，阵列走线105的上方设置电场屏蔽层125，并且在阵列走线105和电场屏蔽层125之间设置有绝缘层115。进一步的，绝缘层115和电场屏蔽层125沿着阵列走线105的延伸方向对应设置在阵列走线105的上方，即：绝缘层115和电场屏蔽层125设置的形状与阵列走线105的形状大致相同。其中，绝缘层115和电场屏蔽层125设置的宽度大于或者等于阵列走线105的宽度，以完全遮蔽阵列走线105，达到理想的屏蔽效果。
本发明实施例中，电场屏蔽层125接地，以保持零电位状态。本实施例中，通过数据驱动芯片103为电场屏蔽层125提供接地的电位。具体而言，数据驱动芯片103的至少一个管脚与电场屏蔽层125的一端连接，并且数据驱动芯片103与电场屏蔽层125连接的管脚接地，以此通过数据驱动芯片103向电场屏蔽层125输送一地电位，使得电场屏蔽层125为零电位状态。
请一并参阅图3，图3是图1所示的液晶显示面板的电容分布示意图。
如图3所示，彩色滤光片基板102在与阵列基板101相对的表面上设置有与彩色滤光片基板102面积相等的整片的导电薄膜121。
本发明实施例中，导电薄膜121和电场屏蔽层125均优选为ITO透明导电薄膜或IZO（Investigation of In-doped ZnO，氧化锌掺杂铟）透明导电薄膜。
液晶显示面板100中，数据线S1、S2以及S3与彩色滤光片基板102的导电薄膜121之间形成电容结构，如图1和图3所示的电容107、108以及109。同理，电场屏蔽层125与导电薄膜121之间也会形成电容结构，如图1和图3所示的电容106。可见，导电薄膜121与阵列走线105之间的电容结构变成了导电薄膜121与电场屏蔽层125之间的电容结构106。值得注意的是，阵列走线105和电场屏蔽线125之间虽然也存在电容结构（未标示），但阵列走线105和电场屏蔽线125之间的电容的容量较小，且不会产生波动。
承前所述，本发明实施例中，虽然导电薄膜121的电位易于受多条数据线S1、S2以及S3同时传输信号的影响而导致其电位产生波动，但是，电场屏蔽层125与导电薄膜121之间的电容106隔离了导电薄膜121的电位波动对阵列走线105的影响。同时，电场屏蔽层125通过接地保持零电位状态，因此导电薄膜121的电位波动并不会对电场屏蔽层125的电位产生影响，电场屏蔽层125的电位保持恒定，因而避免阵列走线105的电位受导电薄膜121电位波动的影响而相应产生波动，从而消除了导电薄膜121的电位变化对阵列走线105的影响，进而避免驱动芯片，特别是扫描驱动芯片104产生误动作。
请参考图4，图4是本发明液晶显示面板的第二实施例的局部结构示意图。以图1所示的虚线AA＇处的剖面图为例，本实施例中的液晶显示面板400与图1所示的液晶显示面板100的主要区别在于：本实施例中的液晶显示面板400中的电场屏蔽层425设置在彩色滤光片基板402上。具体为：阵列基板401上设置阵列走线405，彩色滤光片基板402的表面上设置透明导电层421，且在透明导电层421上对应于阵列走线405的上方处设置电场屏蔽层425，透明导电层421与电场屏蔽层425之间为绝缘层415。进一步的，绝缘层415和电场屏蔽层425沿着阵列走线405的延伸方向对应设置在阵列走线405的上方，即：绝缘层415和电场屏蔽层425设置的形状与阵列走线405的形状大致相同。其中，绝缘层415和电场屏蔽层425设置的宽度大于或者等于阵列走线405的宽度，以完全遮蔽阵列走线405，达到理想的屏蔽效果。
其中，液晶显示面板400的工作原理与液晶显示面板100相同，在此不再赘述。
请参考图5，图5是本发明一种液晶显示装置的实施例的结构示意图，如图5所示，本发明的液晶显示装置500包括背光系统501以及液晶显示面板502。
其中，背光系统501为液晶显示面板502提供光源，液晶显示面板502为图1至图4任一实施例的液晶显示面板。
综上所述，本发明通过在阵列走线与彩色滤光片基板之间设置接地的电场屏蔽层，因电场屏蔽层的电位恒定，消除彩色滤光片基板上的导电薄膜的电位波动对阵列走线的电位的影响，避免阵列走线的电位产生波动从而避免驱动芯片产生误动作，进而提高了液晶显示面板的显示品质。
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。
