Description

液晶面板及显示装置
本发明要求2015年4月27日递交的发明名称为“液晶面板及显示装置”的申请号201510204488.4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
本发明涉及液晶显示技术领域，特别涉及一种液晶面板及显示装置。
背景技术
目前，液晶显示装置作为电子设备的显示部件已经广泛的应用于各种电子产品中，液晶显示装置的液晶面板攸关到液晶显示装置的显示效果，包括视角、明暗程度以及颜色等。其中，薄膜晶体管(thin film transistor，TFT)作为一种开关元件被广泛地应用在液晶显示装置等电子装置中。现有的液晶面板包括相对设置的TFT阵列基板和彩膜基板、以及夹设在阵列基板和彩膜基板之间的液晶，在所述彩膜基板与阵列基板之间形成封闭液晶的胶框。
目前业界发展出一种称为聚合物稳定垂直配向(Ploymer StabilizedVerticalAlignment，PSVA)的技术，此技术乃是在液晶材料中掺入适当浓度的单体化合物(monomer)并且震荡均匀。接着，将混合后的液晶材料置于加热器上加温到达等向性(Isotropy)状态。当液晶混合物降至室温时，液晶混合物会回到向列型(nematic)状态。然后，将液晶混合物注入至液晶盒并施与电压。当施加电压使液晶分子排列稳定时，则使用紫外光或加热的方式让单体化合物进行聚合反应生成聚合物层，由此达到稳定配向的目的。
一般来说，在PSVA的液晶显示面板中，为了增加PSVA的视角，通常采用8畴结构设计。即将每个子像素区域对应的像素电极分成一个大一个小的电极区域，两个电极区域分别设有4畴结构。并且每个电极区域采用一个TFT进行驱动，但由于这种电极区域分割的不对称型容易产生色偏，为了改善色偏，需要增加一个TFT共享开关，而增加一个TFT共享开关会遮蔽部分光线，进而影响显示面板的开口率。

具体实施方式
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作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。
本发明较佳实施方式提供一种显示装置及液晶面板，所述液晶面板为双面显示面板，可实现双面的显示。
请参阅图1，所述液晶面板包括彩膜基板10、阵列基板20及设于所述彩膜基板10与阵列基板20之间的液晶层30，所述彩膜基板10朝向液晶层30的一侧设有公共电极层12，所述阵列基板20朝向液晶层30的一侧设有像素电极层22，所述公共电极层12与所述像素电极层22对称设置，所述公共电极层12包括第一公共电极区121及第二公共电极区122，所述第一公共电极区121及第二公共电极区122通过缝隙间隔，并且以缝隙为中心线对称设置；所述像素电极层22包括第一像素电极区221及第二像素电极区222，所述第一像素电极区221及第二像素电极区222通过缝隙间隔，并且以缝隙为中心线对称设置；所述第一公共电极区121内设有四畴区域，且所述第一公共电极区121与所述第二像素电极区222相对设置，所述第一像素电极区221内设有四畴区域，且所述第一像素电极区221与所述第二公共电极区122相对设置。
本实施例中，所述液晶面板还包括多个单位像素，每个单位像素包括多个独立的子像素。每一个子像素相对应设有一个像素电极。本实施例中，以一个子像素为例进行说明。本领域人员应当理解，以下所述的相对于该子像素的结构同样适用于多个子像素中的其它子像素。所述像素电极层22与所述子像素 对应设置。本实施例中，所述像素电极层22被平均分成两个区域，即所述的第一像素电极区221及第二像素电极区222，进而所述子像素上对应所述第一像素电极区221的部分形成第一子子像素，对应所述第二像素电极区222的部分形成第二子子像素(图未示)。所述第一像素电极区221与第一公共电极区121位于所述液晶面板的两个出光面。本实施例中，所述第一像素电极区221及第二像素电极区222通过缝隙间隔，并且以缝隙为中心线对称设置。所述公共电极层12对应所述第一子子像素及第二子子像素形成对称的所述第一公共电极区121及第二公共电极区122。
所述液晶面板通过第一公共电极区121与所述第二像素电极区222之间产生的电压形成驱动电场而驱动所述第一公共电极区121与所述第二像素电极区222之间的液晶层内液晶进行适当排列。所述第一像素电极区221与所述第二公共电极区122之间产生的电压形成驱动电场而驱动所述第一像素电极区221与所述第二公共电极区122之间之间的液晶层内液晶进行适当排列。所述第一像素电极区221及第二像素电极区222对称设置，且为各个尺寸完全相等的区域，并且所述第一像素电极区221内设有四畴区域，所述第一公共电极区121及第二公共电极区122对称设置且为各个尺寸完全相等的区域，并且所述第一公共电极区121内设有四畴区域，这种均匀分配的方式无论是采用阵列基板20一侧出光还是采用彩膜基板10一侧出光，产生的视角大小相同，不会因为像素电极分配不均匀而产生色偏。同时所述液晶面板的所述第一公共电极区121采用彩膜基板10充电，则所述第二像素电极区222采用阵列基板20充电。所述第一像素电极区221采用阵列基板20充电，则第二公共电极区122采用彩膜基板10充电，在不影响充电效率的前提下，相较于现有技术减少了像素电极的一个开关，可大大增加面板开口率。
进一步的，所述第一公共电极区121与所述第二像素电极区222以所述液晶层30为中心对称设置；所述第二公共电极区122与所述第一像素电极区221以所述液晶层30为中心对称设置。本实施例中，所述第一公共电极区121与所述第二像素电极区222的形状及各个方向的尺寸完全相同。所述第二公共电极区122与所述第一像素电极区221的形状及各个方向的尺寸完全相同。在其它实施方式中，所述第一公共电极区121与所述第二像素电极区222的大小可 以不相同，且第一公共电极区121在第二像素电极区222遮盖的范围内。所述第二公共电极区122与所述第一像素电极区221的大小可以不相同，且所述第二公共电极区122在所述第一像素电极区221遮盖的范围内。
进一步的，所述第一公共电极区121的四畴区域及第一像素电极区221的四畴区域内均设有规则排列的夹缝，进而使所述第一公共电极区121的四畴区域共同形成雪花状图案，所述第一像素电极区221的四畴区域共同形成雪花状图案。
请一并参阅图2与图3，进一步的，所述第一公共电极区121上设有十字形的第一沟槽123，所述第一沟槽123将所述第一公共电极区121分成所述四畴区域。本实施例中，所述四畴区域包括左上方的区域D1、右上方的区域D2、左下方的区域D3及右下方的区域D4。所述区域D1、D2、D3及D4内设有规则排列的所述夹缝125。本实施例中，以D1为例，所述D1内的多个夹缝125以第一沟槽123为起始端，平行的排列于D1内位于所述第一沟槽123的两侧并与所述第一沟槽123成夹角设置，。所述区域D1、D2、D3及D4内的夹缝125共同形成雪花状或“米”字型图案。本实施例中优选为所述区域D1、D2、D3及D4内的夹缝125共同形成“米”字型图案。
进一步的，所述第一像素电极区221上设有十字形的第二沟槽223，所述第二沟槽223将所述第一像素电极区221分成所述四畴区域。本实施例中，所述四畴区域包括左上方的区域B1、右上方的区域B2、左下方的区域B3及右下方的区域B4。所述区域B1、B2、B3及B4内设有规则排列的所述夹缝225。本实施例中，以B1为例，所述B1内以第二沟槽223为起始端，平行的排列于D1内位于所述第二沟槽223的两侧并与所述第二沟槽223成夹角设置，。所述区域B1、B2、B3及B4内的夹缝225共同形成雪花状或“米”字型图案。本实施例中优选为所述区域B1、B2、B3及B4内的夹缝225共同形成“米”字型图案。
进一步的，所述阵列基板20还包括第一金属电极24，所述第一像素电极区221与所述第一金属电极24电性连接。所述第一金属电极24为所述第一像素电极区221提供电量。所述阵列基板20还包括第二金属电极25，所述第二像素电极区222与所述第二金属电极25电性连接。本发明的第一像素电极区 221仅需要一个第一金属电极24提供电量即可。
本发明的所述第一像素电极区及第二像素电极区对称设置，并且所述第一像素电极区内设有四畴区域，所述第一公共电极区及第二公共电极区对称设置并且所述第一公共电极区内设有四畴区域，这种均匀分配的方式无论是采用阵列基板一侧出光还是采用彩膜基板一侧出光，产生的视角大小相同，不会因为像素电极分配不均匀而产生色偏。同时所述液晶面板的所述第一公共电极区采用彩膜基板充电，所述第一像素电极区采用阵列基板充电，在不影响充电效率的前提下，相较于现有技术减少了像素电极的一个开关，可大大增加面板开口率。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
