Description

画素结构与液晶显示装置 技术领域
本申请涉及液晶显示技术领域，尤其涉及一种能改善影像色偏的液晶显示装置及其画素结构。
背景技术
随着光学科技与半导体技术的进步，液晶显示设备已广泛的应用于电子产品显示设备上。液晶显示器具有高画质、体积小、重量轻、低电压驱动、低消耗功率及应用范围广等优点，其已取代传统的阴极射线管成为显示器的主流技术。
相关技术显示，液晶显示设备(Liquid Crystal Display，LCD)包含二基板并有液晶被密封于其间，画素电极及薄膜晶体管(Thin Film Transistor，TFT)被设置于基板上，而相对于各画素电极的彩色滤光膜及共享于各画素的共同电极被设置在另一基板上。彩色滤光膜包含红(R)、绿(G)、蓝(B)三种，而在每一画素中会设有此三种颜色中的一种滤光膜。红、绿、蓝色画素互相邻设而一起构成一画素。
另外，业界相关技术表明，具有高对比度、宽视角特性的多分区垂直配向(Multi-domain Vertical Alignment，MVA)式的液晶显示器可应用于液晶显示电视(Liquid Crystal Display Television，LCD-TV)上，技术特征在于其分割一个画素为四分区(4domain)。MVA技术所制造的液晶显示器具有高对比度、广视角及大尺寸兼容等优点，不过其液晶屏幕于前视与侧视的比较，仍会发现侧视产生色偏现象，这将降低MVA模式的影像质量。要降低色偏，最有效率的方法为采用于薄膜晶体管基板上的八分区(8domain)技术来解决，即画素分区数(domains)从四分区数增加到八分区数或更多，但与之相对的，画素结构复杂，需增加薄膜晶体管基板，显示效果对薄膜晶体管基板 性能要求较高，易受制程影响。
发明内容
鉴于现有技术中的上述问题，本申请提供了相对简单的画素结构，仅改变彩色滤光基板侧的透明导电膜(Indium-Tin Oxide，ITO)的图案，不需要改变阵列基板就可以在单个画素内形成八分区(8domain)，以有效改善面板色偏现象，提高可视角。
鉴于现有技术中的上述问题，本申请提供一种液晶显示装置，提高MVA模式的影像质量。
一方面，本申请实施例提供了一种画素结构，适于单一画素上，包括：第一次画素；以及第二次画素，分别与所述第一次画素之间具有狭缝；其中施加于所述第一次画素上的第一电场大于施加在所述第二次画素上的第二电场。
另一方面，本申请实施例提供了一种液晶显示装置，包括：彩色滤光基板，第一透明导电膜，设置在所述彩色滤光基板上，具有多个画素结构，其中每一所述画素结构包括：第一次画素；及第二次画素，分别与所述第一次画素之间具有狭缝；阵列基板，设置于所述彩色滤光基板的正对方向；第二透明导电膜，设置在所述阵列基板上；以及液晶层，设置于所述阵列基板以及所述彩色滤光基板之间，具有多个液晶分子；其中施加于所述第一次画素上的第一电场大于施加在所述第二次画素上的第二电场。
另一方面，本申请实施例提供了一种液晶显示装置，包括：彩色滤光基板，第一透明导电膜，设置在所述彩色滤光基板上，具有多个画素结构，其中每一所述画素结构包括：第一次画素；及第二次画素，分别与所述第一次画素之间具有狭缝；阵列基板，设置于所述彩色滤光基板的正对方向；第二透明导电膜，设置在所述阵列基板上；以及液晶层，设置于所述阵列基板以及所述彩色滤光基板之间，具有多个液晶分子；其中施加于所述第一次画素上的第一电场大于施加在所述第二次画素上的第二电场，所述第一次画素所 对应的所述多个液晶分子具有4种不同的倾斜方向，所述第二次画素所对应的所述多个液晶分子具有4种不同的倾斜方向。
采用上述技术方案提供了相对简单的画素结构，仅改变彩色滤光基板侧的透明导电膜的图案，不需要改变阵列基板就可以在单个画素内形成八分区(8domain)，以有效改善面板色偏或泛白现象，提高面板视野角。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整的描述。显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
图1为一种现有单个画素内形成八分区的俯视示意图；图2为一种现有亮区和暗区的混合效果剖面示意图，请参阅图1及图2，现有低色偏(Low color shift，LCS)模式的液晶显示面板包括：阵列基板160、彩色滤光基板140以及液晶分子181。设置在阵列基板160及彩色滤光基板140的突起物，当在两基板3、4之间形成电场时，可使液晶分子181往不同的倾斜方向300倾倒，而使亮区第一次画素110形成四分区(4domain)以及暗区第二次画素120也形成四分区的分布(如图1所示)，而由图2所示暗区第二次画素120的液晶分子181倾斜程度相较于亮区第一次画素110的液晶分子181小，因此于单一画素200区域内具有亮区第一次画素110和暗区第二次画素120共八分区，侧看显示面板时通过两个区可以产生相互补偿的效果，从而达到降低色偏的目的。八分区技术对抑制色偏有明显的效果，但与之相对的，画素结构100复杂，显示效果对薄膜晶体管基板4性能要求较高，易受制程影响。
图3为本申请一实施例中一种画素结构100的示意图；图4为本申请一实施例中一种液晶显示装置的剖面示意图；请参阅图3及图4，一种画素结构100，适于单一画素200上，且可蚀刻于彩色滤光基板140的第一透明导电膜150上，包括第一次画素110、第二次画素120以及二狭缝130。于彩色 滤光基板140的第一透明导电膜150上设有二狭缝130，使第一透明导电膜150形成第一次画素110以及第二次画素120。如图4所示，于第一次画素110上施加第一电场E1，于第二次画素120上施加第二电场E2，而第一电场E1大于第二电场E2。
在本实施例中，图6为本申请一实施例中一种单个画素内形成八分区的俯视示意，请参阅图2至图6，由于施加于第一次画素110上的第一电场E1大于施加在第二次画素120上的第二电场E2，因此，位于第一次画素110的区域中的液晶分子181以及位于第二次画素120区域中的液晶分子181会进一步产生不同的程度的倾倒(类似于图2所示)。如此一来，如图6所示，除了由俯视图可见第一次画素110所对应的多个液晶分子181及第二次画素120所对应的多个液晶分子181具有四种现有的倾斜方向300外，第二次画素120所对应的多个液晶分子181的倾斜程度受第二电场E2影响会较第一次画素110所对应的多个液晶分子181小，因此画素结构100在单个画素内可以在四分区画素基础上，每一个分区又分为亮区和暗区两个区，从而形成八分区。因此，仅改变彩色滤光基板140侧的第一透明导电膜150的图案，不需要改变阵列基板160就可以在单个画素内形成八分区，以有效改善面板色偏或泛白现象，提高面板视野角。
此外，在具体实施例中，如图7、图9、图11所示的画素结构100具有横向分布的特征，可于面板的左右两侧向面内第一次画素110区、第二次画素120区分别输入电场信号；如图8、图10、图12所示的画素结构100具有纵向分布的特征，可于面板的上下两侧向面内第一次画素110区、第二次画素120区分别输入电场信号，其中，在实施例中，输入第一次画素110上的电压V1与输入第二次画素120上的电压V2压差为：0＜V1-V2＜3V。
本实施例的液晶显示装置可为LCD显示面板、有机发光二极管(Organic Light Emitting Display，OLED)显示面板、量子点发光二极管(Quantum Dot light Emitting Diode，QLED)显示面板、MVA型液晶面板、曲面显示面板或其他显示面板。
另外，在具体实施例中，如图7、图8、图9、图10、图11、图12所示，于彩色滤光基板140侧的第一透明导电膜150刻蚀成具有第一次画素110的面积与二第二次画素120的面积比例介于1:1～1:2之间，以符合同时改善色偏与提供适当亮度的需求。
此外，如图7、图8、图9、图10、图11、图12所示，于彩色滤光基板140侧的第一透明导电膜150设有的画素结构100图案可以是长方形、六边形或者其它形状，并不限于此。
在具体实施例中，如图11和图12所示，于彩色滤光基板140侧的第一透明导电膜150设有成具有第一次画素110与第二次画素120相互交叠的画素结构100图案，使亮暗区划分更加精细。
在另一实施例中，请参阅图3及图4，一种液晶显示设备，包括彩色滤光基板140、第一透明导电膜150、第二透明导电膜170以及阵列基板160。彩色滤光基板140可为玻璃基板141，另外，可于玻璃基板141上制作防反射的遮光层142，即为(Black Matrix，BM)层，再依序制作上具有透光性红、绿、蓝RGB三原色的彩色滤光膜层143(滤光层的形状、尺寸、色泽配列，依不同用途的液晶显示器而异)，然后在滤光层上涂布(Coating)一层平滑的保护层144(Over Coat)，最后镀上第一透明导电膜150。
在本实施例中，第一透明导电膜150是设置在彩色滤光基板140上，具有多个画素结构100，每一画素结构100包括：第一次画素110以及第二次画素120系分别与第一次画素110之间具有二狭缝130。而每一画素结构100适于单一画素200上，且可用蚀刻的方式来形成于彩色滤光基板140的第一透明导电膜150上。例如，于彩色滤光基板140的第一透明导电膜150上蚀刻二狭缝130，使第一透明导电膜150形成第一次画素110以及第二次画素120。
此外，本实施例的液晶显示设备的阵列基板160设置于彩色滤光基板140的正对方向。第二透明导电膜170系设置在阵列基板160上，而第二透明导电膜170的狭缝190的延伸方向与第一透明导电膜150的二狭缝130的延伸 方向相对应。另外，一液晶层180，设置于阵列基板160以及彩色滤光基板140之间，具有多个液晶分子181(类似于图2所示)。如图4所示，于第一次画素110上施加第一电场E1，于第二次画素120上施加第二电场E2，而第一电场E1大于第二电场E2。
在本实施例中，图6为本申请一实施例中一种单个画素内形成八分区的俯视示意，请参阅图2至图6，由于施加于第一次画素110上的第一电场E1大于施加在第二次画素120上的第二电场E2，因此，位于第一次画素110的区域中的液晶分子181以及位于第二次画素120区域中的液晶分子181会进一步产生不同的程度的倾倒(类似于图2所示)。如此一来，如图6所示，除了由俯视图可见第一次画素110所对应的多个液晶分子181及第二次画素120所对应的多个液晶分子181具有四种现有的倾斜方向300外，第二次画素120所对应的多个液晶分子181的倾斜程度受第二电场E2影响会较第一次画素110所对应的多个液晶分子181小，因此画素结构100在单个画素内可以在四分区画素基础上，每一个分区又分为亮区和暗区两个区，从而形成八分区。因此，仅改变彩色滤光基板140侧的第一透明导电膜150的图案，不需要改变阵列基板160就可以在单个画素内形成八分区，以有效改善面板色偏或泛白现象，提高面板视野角。
此外，在具体实施例中，如图7、图9、图11所示的画素结构100具有横向分布的特征，可于面板的左右两侧向面内第一次画素110区、第二次画素120区分别输入电场信号；如图8、图10、图12所示的画素结构100具有纵向分布的特征，可于面板的上下两侧向面内第一次画素110区、第二次画素120区分别输入电场信号，其中，在实施例中，输入第一次画素110上的电压V1与输入第二次画素120上的电压V2压差为：0＜V1-V2＜3V。
另外，在具体实施例中，如图7、图8、图9、图10、图11、图12所示，于彩色滤光基板140侧的第一透明导电膜150刻蚀成具有第一次画素110的面积与二第二次画素120的面积比例介于1:1～1:2之间，以符合同时改善色偏与提供适当亮度的需求。
此外，如图7、图8、图9、图10、图11、图12所示，于彩色滤光基板140侧的第一透明导电膜150刻蚀的画素结构100图案可以是长方形、六边形或者其它形状，并不限于此。
在具体实施例中，如图11和图12所示，于彩色滤光基板140侧的第一透明导电膜150刻蚀成具有第一次画素110与第二次画素120相互交叠的画素结构100图案，使亮暗区划分更加精细。
本实施例的画素结构100适用的液晶显示装置可为LCD显示面板、OLED显示面板、QLED显示面板、垂直配向(Vertical Alignment，VA)型液晶面板、曲面显示面板或其他显示面板，请参阅图3及图4，一种VA型液晶面板的液晶显示设备，包括彩色滤光基板140、第一透明导电膜150、第二透明导电膜170以及阵列基板160。彩色滤光基板140可为玻璃基板141，另外，可于玻璃基板141上制作防反射的遮光层142，即为BM层(Black Matrix)，再依序制作上具有透光性红、绿、蓝(RGB)三原色的彩色滤光膜层143(滤光层的形状、尺寸、色泽配列，依不同用途的液晶显示器而异)，然后在滤光层上涂布(Coating)一层平滑的保护层144(Over Coat)，最后镀上第一透明导电膜150。
在本实施例中，第一透明导电膜150是设置在彩色滤光基板140上，具有多个画素结构100，每一画素结构100包括：第一次画素110以及二第二次画素120系分别与第一次画素110之间具有二狭缝130。而每一画素结构100适于单一画素200上，且可用蚀刻的方式来形成于彩色滤光基板140的第一透明导电膜150上。例如，于彩色滤光基板140的第一透明导电膜150上蚀刻二狭缝130，使第一透明导电膜150形成第一次画素110以及第二次画素120。

在本实施例中，图6为本申请一实施例中一种单个画素内形成八分区的俯视示意，请参阅图2至图6，由于施加于第一次画素110上的垂直方向的第一电场E1大于施加在第二次画素120上的垂直方向的第二电场E2，因此，位于第一次画素110的区域中的液晶分子181以及位于第二次画素120区域中的液晶分子181会进一步产生不同的程度的倾倒(类似于图2所示)。如此一来，如图6所示，除了由俯视图可见第一次画素110所对应的多个液晶分子181及第二次画素120所对应的多个液晶分子181具有四种现有的倾斜方向300外，第二次画素120所对应的多个液晶分子181的倾斜程度受第二电场E2影响会较第一次画素110所对应的多个液晶分子181小，因此画素结构100在单个画素内可以在四分区画素基础上，每一个分区又分为亮区和暗区两个区，从而形成八分区。因此，仅改变彩色滤光基板140侧的第一透明导电膜150的图案，不需要改变阵列基板160就可以在单个画素内形成八分区，以有效改善面板色偏或泛白现象，提高面板视野角。
