Description

显示面板及显示装置
【技术领域】
本发明涉及液晶显示领域，尤其涉及一种显示面板及具有该显示面板的显示装置。
【背景技术】
薄膜晶体管液晶显示装置（Thin Film Transistor-Liquid Crystal Display, TFT- LCD）主要包括阵列基板、彩膜基板和位于二者之间的液晶层。
阵列基板上设置多条沿第一方向彼此间隔设置的扫描线和多条沿垂直于第一方向的第二方向间隔设置的数据线。多条扫描线和多条数据线交叉设置。
彩膜基板上设置黑矩阵、多个RGB（Red-Green-Blue，红-绿-蓝）光阻以及公共电极。阵列基板的扫描线与黑矩阵正对。公共电极设置于彩膜基板上朝向阵列基板的一侧且公共电极覆盖黑矩阵和RGB电阻。
液晶显示装置处于零灰阶状态时，扫描线与彩膜基板上的与之对应的公共电极区域形成电场使得电场内部和电场周围的液晶发生扭转，使得该区域通过液晶层透光。此时，若彩膜基板和阵列基板正对，则黑矩阵阻挡了光线的进一步传播；否则，若液晶显示装置搬运过程中彩膜基板和阵列基板发生弯曲或者二者对位不准，则可能导致彩膜基板和阵列基板发生错位，进而使得黑矩阵相对数据线发生偏移，零灰阶的状态下则可能会出现云团状的光斑。
【发明内容】
本发明主要解决的技术问题是提供一种显示面板及显示装置，以确保零灰阶的状态下不会出现漏光现象。
为解决上述技术问题，本发明采用的一个技术方案是：一种显示面板，包括相对设置的阵列基板和彩膜基板，以及夹置于阵列基板与彩膜基板之间的液晶层，阵列基板包括多条彼此间隔设置的扫描线和多条间隔设置且与扫描线绝缘交叉的数据线，扫描线包括与数据线交叉的第一区域和未与数据线交叉的第二区域；彩膜基板包括黑矩阵以及公共电极；扫描线与黑矩阵相对设置，公共电极覆盖黑矩阵，且公共电极上设置有与扫描线对应的镂空结构，镂空结构与第二区域对应设置；以避免镂空结构处的液晶层的液晶分子在扫描线上施加的扫描电压和公共电极上施加的公共电压的作用下产生偏转。
其中，扫描线沿第一方向延伸且沿垂直于第一方向的第二方向彼此间隔设置，数据线沿第二方向延伸且沿第一方向彼此间隔设置，镂空结构沿第一方向的尺寸大于或等于第二区域沿第一方向的尺寸。
其中，公共电极的与第一区域对应的位置沿第一方向的尺寸不超过数据线沿第一方向的尺寸。
其中，镂空结构位于黑矩阵的边缘两侧。
其中，镂空结构的宽度大于黑矩阵，以使黑矩阵经镂空结构外露。
为解决上述技术问题，本发明采用的另一个技术方案是：一种显示面板，包括相对设置的阵列基板和彩膜基板，以及夹置于阵列基板与彩膜基板之间的液晶层，其中，阵列基板包括多条彼此间隔设置的扫描线；彩膜基板包括黑矩阵以及公共电极；扫描线与黑矩阵相对设置，公共电极覆盖黑矩阵，且公共电极上设置有与扫描线对应的镂空结构，以避免镂空结构处的液晶层的液晶分子在扫描线上施加的扫描电压和公共电极上施加的公共电压的作用下产生偏转。
其中，镂空结构沿扫描线的延伸方向间隔设置。
其中，阵列基板进一步包括多条间隔设置且与扫描线绝缘交叉的数据线，扫描线包括与数据线交叉的第一区域和未与数据线交叉的第二区域，镂空结构与第二区域对应设置。
其中，扫描线沿第一方向延伸且沿垂直于第一方向的第二方向彼此间隔设置，数据线沿第二方向延伸且沿第一方向彼此间隔设置，镂空结构沿第一方向的尺寸大于或等于第二区域沿第一方向的尺寸。
其中，公共电极的与第一区域对应的位置沿第一方向的尺寸不超过数据线沿第一方向的尺寸。
其中，镂空结构位于黑矩阵的边缘两侧。
其中，镂空结构的宽度大于黑矩阵，以使黑矩阵经镂空结构外露。
其中，镂空结构沿扫描线的延伸方向连续设置。
其中，公共电极为透明电极层。
为解决上述技术问题，本发明采用的另一个技术方案是：一种显示装置包括相对设置的阵列基板和彩膜基板，以及夹置于阵列基板与彩膜基板之间的液晶层，阵列基板包括多条彼此间隔设置的扫描线；彩膜基板包括黑矩阵以及公共电极；扫描线与黑矩阵相对设置，公共电极覆盖黑矩阵，且公共电极上设置有与扫描线对应的镂空结构，以避免镂空结构处的液晶层的液晶分子在扫描线上施加的扫描电压和公共电极上施加的公共电压的作用下产生偏转。
其中，阵列基板进一步包括多条间隔设置且与扫描线绝缘交叉的数据线，扫描线包括与数据线交叉的第一区域和未与数据线交叉的第二区域，镂空结构与第二区域对应设置。
其中，扫描线沿第一方向延伸且沿垂直于第一方向的第二方向彼此间隔设置，数据线沿第二方向延伸且沿第一方向彼此间隔设置，镂空结构沿第一方向的尺寸大于或等于第二区域沿第一方向的尺寸。
其中，扫描线沿第一方向延伸且沿垂直于第一方向的第二方向彼此间隔设置，数据线沿第二方向延伸且沿第一方向彼此间隔设置，镂空结构沿第一方向的尺寸大于或等于第二区域沿第一方向的尺寸。
其中，镂空结构位于黑矩阵的边缘两侧。
其中，镂空结构的宽度大于黑矩阵，以使黑矩阵经镂空结构外露。
本发明的有益效果是：与现有技术相比，本发明显示面板的公共电极上设置有与扫描线对应的镂空结构，从而避免镂空结构处的液晶层的液晶分子在扫描线上施加的扫描电压和公共电极上施加的公共电压的作用下产生偏转。这样一来，即便在显示面板或显示装置搬运过程中彩膜基板和阵列基板发生错位，零灰阶的状态下，镂空结构阻止了电场的外延，进而减小了液晶分子的偏转区域，从而避免显示面板出现云团状光板的漏光现象。

【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。
请参照图1至图4，本发明第一实施方式显示面板包括相对设置的阵列基板10和彩膜基板20，以及夹置于阵列基板10和彩膜基板20之间的液晶层30。
阵列基板10包括多条彼此间隔设置的扫描线11。图示仅为本发明显示面板的局部图，仅以一条扫描线11及其对应的彩膜基板20的公共电极的局部区域为例对本发明进行描述。图示不应构成对本发明保护范围的限制。
彩膜基板20包括黑矩阵201和公共电极202。扫描线11与黑矩阵201相对设置，公共电极202覆盖黑矩阵201。公共电极202是透明电极层。公共电极202上设置有与扫描线11对应的镂空结构20A，从而避免镂空结构20A处的液晶层30的液晶分子31在扫描线11上施加的扫描电压和公共电极202上施加的公共电压的作用下产生偏转。
具体来讲，阵列基板10的扫描线11沿第一方向X延伸且多条扫描线11沿垂直于第一方向X的第二方向Y彼此间隔设置。此外，阵列基板10还包括多条与扫描线11绝缘交叉的数据线12。数据线12沿第二方向Y延伸且多条数据线12沿第一方向X彼此间隔设置。扫描线11包括与数据线12交叉的第一区域111和未与数据线交叉的第二区域112。本实施例中，镂空结构20A与第二区域112对应且镂空结构20A位于黑矩阵201的两侧；换句话说，黑矩阵201的两侧、沿扫描线11的延伸方向即第一方向X间隔设置镂空结构20A，第一区域111对应位置处的公共电极将相邻的镂空结构20A隔开，确保公共电极202的不同区域电连接；宏观状态下，镂空结构20A以间断的缝隙呈现出来。
为了取得更好的防漏光效果，优选地，镂空结构20A沿第一方向X的尺寸大于或等于扫描线11的第二区域112沿第一方向X的尺寸。换句话说，镂空结构20A位于黑矩阵的边缘两侧与第二区域112完全正对的位置上或者镂空结构20A位于黑矩阵的边缘两侧与第二区域112完全正对的位置上和第一区域111的部分位置上。因此，公共电极202的与第一区域111对应的位置沿第一方向X的尺寸W1不超过数据线12沿第一方向X的尺寸W2。公共电极202的与第一区域111对应的位置亦可以理解为公共电极202的不同区域的连接部202A，连接部202A的宽度亦即W1。数据线12沿第一方向X的尺寸亦即数据线12的宽度。
请参照图2，镂空结构20A的设置，使得显示面板处于零灰阶状态时，扫描线11上施加的扫描电压和公共电极202上施加的公共电压在镂空结构处中断，因此在镂空结构对应的位置处液晶分子不会发生偏转，避免该位置处的光线透过液晶层进一步传播，在彩膜基板20和阵列基板10发生错位时也不会出现云团状的光斑。
图5至图6为本发明显示面板的第二实施方式。本实施方式显示面板包括相对设置的阵列基板10、彩膜基板21，以及夹置于阵列基板10和彩膜基板21之间的液晶层30。阵列基板10和液晶层30的具体结构请参照上述实施方式。
本实施方式中彩膜基板21包括黑矩阵211和公共电极212。公共电极212上设置有与扫描线11对应的镂空结构21A。镂空结构21A与第二区域112对应且镂空结构21A的宽度大于黑矩阵211的宽度，以使黑矩阵211经镂空结构21A外露。黑矩阵211位于镂空结构的中间位置，因此黑矩阵211与镂空结构周侧的公共电极212呈一定间隙设置。
本实施方式的显示面板处于零灰阶状态时，扫描线11上施加的扫描电压上方为公共电极212的镂空结构，因此不会在扫描线11的第一区域上与公共电极212之间形成电场，镂空结构对应的位置处液晶分子不会发生偏转，避免该位置处的光线透过液晶层进一步传播，在彩膜基板21和阵列基板10发生错位时也不会出现云团状的光斑。
图7所示为本发明显示面板第三实施方式中应用的公共电极222的示意图。公共电极222上设置沿扫描线的延伸方向连续设置的镂空结构22A。为了确保公共电极222的不同区域具有相同的电压，公共电极222的外侧设置连接结构（未标示）。镂空结构22A的设置使得显示面板在零灰阶的状态下扫描线11上施加的扫描电压上方与公共电极222的镂空结构22A正对，因此不会在扫描线11上与公共电极222之间形成电场，镂空结构对应的位置处液晶分子不会发生偏转，避免该位置处的光线透过液晶层进一步传播，在彩膜基板和阵列基板10发生错位时也不会出现云团状的光斑。
本发明进一步提供一种显示装置，该显示装置包括前述实施方式中描述的显示面板。
与现有技术相比，本发明显示面板的公共电极202、212、222上设置有与扫描线11对应的镂空结构20A、21A、22A，从而避免镂空结构处的液晶层30的液晶分子31在扫描线11上施加的扫描电压和公共电极上施加的公共电压的作用下产生偏转。这样一来，即便在显示面板或显示装置搬运过程中彩膜基板和阵列基板发生错位，零灰阶的状态下，镂空结构20A、21A、22A阻止了电场的外延，进而减小了液晶分子的偏转区域，从而避免显示面板出现云团状光板的漏光现象。
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。
