 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本揭示可用以实施的特定实施例。
随着显示面板制备技术的不断发展，人们对显示面板的质量以及显示效果均提出了更高的要求。
如图1所示，图1为现有技术中提供的多畴显示面板对应的像素电路总体架构图。在显示面板显示区域对应的像素显示区中，多个子像素阵列排列，如在显示面板的显示区域内M*N的阵列进行排布。每一子像素均分为主像素（Main）区103和次像素（Sub）区104，对应于每一行子像素分别设置一条扫描信号线100，对应于每一列子像素分别设置一条数据信号线101，扫描信号线100和数据信号线101同时电性连接每一个子像素，并提供扫描信号和数据信号至对应行或者列中的子像素的主像素区103与次像素区104。
当上述像素电路工作时，分别向对应的子像素提供驱动电压，由于主像素区103与次像素区104所提供的主数据信号电压与次数据信号电压的极性相同，在同一帧画面中，施加在同一子像素内主像素区103与次像素区104上的电压极性相同，液晶的偏转角度相同，当从不同的角度进行观察时，会出现一定的色偏问题，进而降低显示面板的显示效果。
本发明实施例提供一种显示面板及显示装置，以有效的改善显示面板在显示时容易出现色偏，显示效果不理想的问题，并提高显示面板的综合性能。
如图2所示，图2为本发明实施例中提供的显示面板的膜层结构示意图。本申请实施例中，显示面板包括第一基板200、第二基板201、液晶层203以及电极202。
具体的，第一基板200与第二基板201相对设置，液晶层203设置在第一基板200与第二基板201之间对应的区域内，同时，电极202设置在第二基板201靠近第一基板200的一侧。优选的，可将该电极202设置在第二基板201与第一基板200相对的侧面上。
本申请实施例中，该第一基板200优选为阵列基板，第二基板201优选为彩膜基板，在阵列基板上设置有多个薄膜晶体管，并在阵列基板上设置像素电极，该像素电极可按照常规的像素电极结构进行设置。同时，在第一基板200与第二基板201对应的显示区域内，其被分割成多个像素显示区域20，在该像素显示区域20内包括多个阵列排布的像素单元。其中，该像素单元内设置有像素电极。该像素电极对应设置在像素显示区域20内，多个像素显示区域20构成显示面板的发光显示区。
其中，第二基板201与第一基板200对盒设置，在该第二基板201朝向第一基板200的一侧设置有多个电极202。每个电极202与每个像素单元中的像素电极对应设置。即该电极202与该像素显示区域20对应设置，从而向像素显示区域20内的薄膜晶体管提供驱动信号。
如图3所示，图3为本申请实施例提供的像素显示区域结构示意图。结合图1以及图2，本申请实施例中，在像素显示区域20内，多个子像素阵列设置。同时，每一个子像素对应的像素显示区域20还包括主像素区域103以及次像素区域104。主像素区域103设置在次像素区域104的至少一侧。本申请实施例中，在每个主像素区域103和次像素区域104内均分割成4个区域，4个区域内分别对应4个液晶畴，从而形成8畴显示面板。优选的还可设置为其他数目的液晶畴，这里不再详细赘述。
本申请实施例中，通过电极实现对不同畴对应区域内的液晶进行控制。具体的，如图4所示，图4为本申请实施例提供的电极的结构示意图。具体的，在设置本申请实施例中的电极202时，电极202与显示面板的像素显示区域对应设置。其中，电极202包括主电极402以及次电极403。主电极402与次电极403相间隔设置，该主电极与次电极之间相互不接触，且该次电极403设置在主电极402的内部，即在每个像素显示区域内，该主电极402围绕次电极403设置，以便对不同的电极进行控制，并达到对显示面板显示效果的调控。
优选的，在设置主电极402和次电极403时，主电极402内设置有避让间隙，从而保证主电极和次电极之间不相互接触。同时，主电极402对应设置在主像素区域和次像素区域内，次电极403也对应设置在主像素区域和次像素区域内。
进一步的，本申请实施例中的显示面板还包括第一公共电极400以及第二公共电极402。其中，第一公共电极400和第二公共电极401分别设置在主电极402以及次电极403的两侧。
本申请实施例中，该主电极402通过对应的电极引线与第二公共电极401电连接，该次电极403通过对应的另一电极引线与第一公共电极400电连接。即该第二公共电极401向该主电极402提供第一电压信号，该第一公共电极400向该次电极403提供第二电压信号。本申请实施例中，该第一电压信号和第二电压信号不同。当对显示面板内的液晶进行作用时，通过第一公共电极400和第二公共电极401分别向次电极403和主电极402提供不同的工作电压。
由于主电极402和次电极403上具有不同的电压值，因此，对应区域内所形成的电场就会存在区别。本申请实施例中，位于该主电极对应区域内的液晶在第一电压信号下具有第一偏转方向，位于该次电极对应区域内的液晶在第二电压信号下具有第二偏转方向。当其对液晶作用时，会使得不同区域内的液晶，如主像素区域103或者次像素区域104内不同位置处的液晶所处的电场强度不同，进而在不同电场力的作用下发生不同角度的偏转，从而实现降低显示面板色偏，并改善显示效果的目的。优选的，本申请实施例中，该第一偏转方向可小于第二偏转方向，从而通过不同的偏转方向的液晶对不同区域内的光线进行调节，而保证整个像素显示区域显示效果的一致性。
如图5所示，图5为本申请实施例中提供的另一电极的结构示意图。本申请实施例中，该主电极402以第一主电极4021和第二主电极4022，次电极403以第一次电极4031和第二次电极4032为例进行说明。
优选的，次电极403设置在第一主电极4021和第二主电极4022之间，并与两侧的主电极相间隔，且不互相接触。同时，第一主电极4021和第二主电极4022相对该次电极403对称设置。第一主电极4021与第二主电极4022在主像素区域103和次像素区域104内分别形成有第一空白区60和第二空白区61。本申请实施例中，主像素区域103的面积可小于次像素区域104的面积。优选的，主像素区域103与次像素区域104之间的面积比为2：3，以对不同像素区域内对应的电极大小进行调控。同时，其形成的第一空白区60的面积可小于第二空白区61的面积。
进一步的，该第一空白区60和第二空白区61的形状可设置为相同的形状，如均设置为矩形、方形、圆形以及椭圆形或者其他形状，这里不做具体限定。本申请实施例中，两空白区均以矩形为例进行说明。
本申请实施例中，该第一空白区60和第二空白区61可设置在主像素区域和次像素区域的中心区域附近。从而保证在对不同像素区域内的液晶进行控制时，具有较好的一致性，以保证显示面板的显示效果。
进一步的，本申请实施例中，该次电极403包括第一次电极4031和第二次电极4032。其中，第一次电极4031设置在主像素区域103内，第二次电极4032设置在次像素区域104内。同时，该第一次电极4031对应设置在第一空白区60内，第二次电极4032对应设置在第二空白区61内。且第一次电极4031与第二次电极4032之间不接触。
本申请实施例中，该第一次电极4031与第二次电极4032均设置为矩形结构，且第一次电极4031的面积小于第二次电极4032的面积，优选的，第一次电极4031与第二次电极4032之间的面积比可设置为2：3。
优选的，该电极还设置有一连接槽50。连接槽50连接第一空白区60和第二空白区61。该连接槽50可包括多段，多段对应的与不同的空白区连通。如连接槽51与第一空白区60的一侧连接，连接槽52同时与第一空白区60和第二空白区61连接，同时，连接槽54与第二空白区61的一侧连接。从而形成该次像素电极的排布结构。
本申请实施例中，其连接槽51、连接槽52以及连接槽54的宽度可设置为相同。优选的，该宽度设置为10um-22um，以保证不同电极之间具有较好的一致性，从而精确的对不同区域内的液晶进行调控。
同时，第一次电极4031和第二次电极4032之间还设置有连接电极501，连接电极501设置在对应的连接槽内，从而使得不同的第二次电极4032之间电性连接。本申请实施例中，连接电极501与两侧的第一主电极4021和第二主电极4022之间的间距距离设置为4um-10um，从而防止不同主干电极之间容易出现短路以及相互干扰的问题，并达到保证显示面板具有较好的可靠性的目的。
进一步的，本申请实施例中，为了保证该电极具有较好的调控效果，在设置主像素区域103和次像素区域104内的不同电极时，在主像素区域103内，第一空白区60内的第一次电极4031的面积与该区域内的第一主电极4021或者第二主电极4022的面积之比为1：3。同时，在次像素区域104内，第二空白区61内的第二次电极4032的面积与该区域内的第一主电极4021或者第二主电极4022的面积之比为1：3。或者上述不同的电极之间的面积比设置为其他数量关系，具体的，可根据实际产品的显示效果进行设置，这里不做具体限定。
优选的，上述空白区的形状以及对应的次电极的形状还可设置为其他形状，同时本申请实施例中的空白区的数量也可根据实际产品进行设定。
具体的，如图6所示，图6为本申请实施例中提供的多畴像素区域中的视角示意图。在该多畴像素区域内，该区域对应的上下、左右位置处的视角较好，而在区域6、区域7、区域8以及区域9内，根据其等效示意图可知其视角较差。而本申请实施例中，在上述视角较差区域内设置有不同的电极，该电极可接入不同的电压信号，通过不同的电压信号以该区域内的液晶进行调控，进而改善显示效果，并提高其视角可视化。
如图7所示，图7为本申请实施例中液晶在电极作用下的偏转立体效果示意图。当采用本申请实施例中的电极结构时，由于主电极接入第一电压信号，次电极接入第二电压信号，第一电压信号与第二电压信号不同。因此当液晶发生偏转时，会对应的形成第一角度偏转液晶和第二角度偏转液晶。其中，该第一角度偏转液晶的偏转角为θA，对应于主电极所在区域；第二角度偏转液晶的偏转角度为θB，对应于次电极所在区域。此时，两种不同角度的液晶会对光线产生不同的作用，进而可对全视野范围内的视角进行补偿，从而有效的改善了显示面板在某些区域内视角视野较差的问题，并改善显示面板的色偏问题。
进一步的，如图8所示，图8为本申请实施例中提供的次像素区域内液晶的作用效果示意图。该区域以次像素区域104为例进行说明，在该次像素区域104的中心区域处设置有第二空白区61，且在该第二空白区61对应位置膜层上设置有第二次电极，并在其他区域内设置有主电极。当向主电极和次电极提供不同的电压信号时，会在不同的区域内形成不同的电场大小。
优选的，该次电极上提供第二电压信号，主电极上提供第一电压信号，且第一电压信号的电压值小于第二电压信号的电压值。此时，次电极对应区域内的电场强度大于主电极对应区域内的电场强度。液晶在主电极和次电极的作用下会发生不同角度的偏转，最终使得第二空白区61内的液晶偏转的角度大于其他区域内的液晶偏转角度。以有效的对像素区域内的显示效果进行改善。
对应的，如图9所示，图9为本申请实施例中提供的液晶偏转示意图。结合图6-图8，本申请实施例中，在显示区域内，其主电极作用的液晶区域为第一区域80，其次电极作用的液晶区域为第二区域81。此时，可知，第二区域81内的液晶偏转角度大于第一区域80内的液晶的偏转角度。本申请实施例中，在第一区域80内，液晶的第一偏转方向对应的偏转角度为0.8°~1.0°，优选为0.9°。在第二区域81内，其液晶的第二偏转方向对应的偏转角度为1.2°~1.4°，优选为1.3°。从而对不同区域内的液晶进行控制，使不同像素畴内的液晶发生不同程度的倾斜，进而改善视角色偏问题。
本申请实施例中，在制备主电极和次电极时，可通过黄光制程工艺进行制备，并最终得到本申请实施例中所需要的电极结构。
同时，本申请实施例还提供一种显示装置，该显示装置包括显示面板。且该显示面板内部设置有本申请实施例中所提供的电极结构，该电极包括主电极和次电极，主电极接入第一电压信号，次电极接入第二电压信号，且该第一电压信号好第二电压信号不同，进而通过不同的电压信号以对不同像素畴区域内的液晶进行控制，并减小显示面板的色偏，提高显示面板的显示效果。
进一步的，该显示装置可为：OLED面板、手机、电脑、电子纸、显示器、笔记本电脑、数码相框等任何具有显示功能的产品或部件，其具体类型不做具体限制。
