Description

显示面板及其显示方法 技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板及其显示方法。
背景技术
薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display；TFT-LCD)由于色彩度高、体积小、功耗低等优势，在目前平板显示领域中仍占主流位置。就目前主流市场上的薄膜晶体管液晶显示器其显示面板而言，大致可分为三种类型，分别是扭曲向列(Twisted Nematic；TN)或超扭曲向列(Super Twisted Nematic；STN)型、平面转换(In-Plane Switching；IPS)型、以及垂直配向(Vertical Alignment；VA)型。其中垂直配向型液晶显示器相对其他种类的液晶显示器具有极高的对比度，在大尺寸显示，如电视等方面具有非常广的应用。
在垂直配向型液晶显示器的相关领域中，目前业界大量应用一种聚合物安定化垂直配向技术(Polymer Stabilized Vertical Alignment，PSVA)。此种技术将光致聚合分子掺杂与液晶中，并施与液晶层适当的电压，当施加电压使液晶分子排列稳定时候，使用紫外光照射或加热的方式让液晶中的光致聚合分子进行聚合反应，生成聚合物层使液晶有一个初始的预倾角(Pre-tilt Angle)，从而达到聚合物安定化垂直配向的目的。由于在配向膜表面形成聚合物突起，使液晶分子具有预倾角，因此能够使液晶显示面板具有高对比度、宽视角、低功耗、响应快且穿透率高等益处。
然而，在从低灰阶到高灰阶转变过程中，液晶从竖直状态转向水平状态，会导致使用者在不同的视角下注视显示器面板时，光线会经过不同的相位差而直接影响显示器面板的视觉特性。为了增大视角减少色差，相关领域中通常使用多个液晶象限(Domain)进行补偿。

图1是一示例性的显示面板截面图，显示施加电压于液晶层使液晶分子产生预倾角。如图1所示，显示面板1主要包括了第一基板10、液晶层12、 第二基板14。在第一基板10的第一表面具有一平坦分布的公共电极100，在公共电极100的第一表面具有一配向膜102。第二基板14，位于所述第一基板10第一侧，并面对所述第一基板10。在第二基板14的第二表面具有阵列分布的多个像素电极140，在像素电极140的第二表面，则具有一配向膜142。
液晶层12，填充于第一基板10与第二基板14间，亦即位于公共电极100与像素电极140间。液晶层12包括了液晶分子120与光致聚合分子122。在后续的配向制程中，可施与液晶层12适当的电压，当施加电压使液晶分子120排列稳定时候，使用紫外光照射或加热的方式让液晶层12中的光致聚合分子122进行聚合反应，生成聚合物层使液晶分子120有一个初始的预倾角(Pre-tilt Angle)，从而达到配向的效果。
图2是一示例性的像素电极俯视图。为了增大视角减少色差，像素电极20制作为具有一具有鱼骨图案的像素电极。像素电极20包含环绕周围的边框200、中央垂直沿伸的主干(main trunk)201、中央水平沿伸的主干202、以及与X轴夹角为±45度，±135度的四组分支部203组成。垂直主干201和水平主干202将一像素的面积平均分成四个区域(domain)，每个区域包括了斜向沿伸的分支部203平铺组成。分支部203的产生，是因为在像素电极20的四个区域中分别形成了多个镂空的长条形开口，这些长条形的开口沿伸的方向，随着区域的不同，分别与X轴夹角为±45度，±135度。如此，整个像素电极20在边框200中，会形成了上下和左右分别镜像对称的鱼骨图案结构。由于在像素电极20上的液晶分子会分别沿着四组分支部203的角度分布，因此在不同的方向上观看时，会有补偿色偏的作用。
图3是本申请一种显示面板截面图。如图3所示，显示面板3的主要组件包括了第一基板30、第二基板31、液晶层32、第一透明电极300、第二透明电极310、第三透明电极311以及绝缘层312。
第一透明电极300，位于第一基板30第一表面。在一实施例中，所述第一基板30为一玻璃基板，并且为一彩色滤光片基板。在另一实施例中，第一透明电极300的材料为氧化铟锡(ITO)，并且所述第一透明电极300为平板状的公共电极。
第二基板31，位于所述第一基板30第一侧，面对第一基板30。第二透明电极310，位于所述第二基板31第二侧，面对所述第一透明电极300与第 一基板30。在一实施例中，所述第二基板31为一玻璃基板，并且为一像素阵列基板。在另一实施例中，第二透明电极310的材料为氧化铟锡(ITO)，并且所述第二透明电极310为具有鱼骨图案的像素电极。
第三透明电极311，位于所述第二基板31与所述第二透明电极310间，面对所述第二透明电极310，所述第三透明电极311并与部份所述第二透明电极310重叠。如图中所示，第三透明电极311，形成于第二基板31的第二表面，且位于第二透明电极310的第一侧，与部份第二透明电极310发生重叠，但彼此间并无电性连结。在一实施例中，所述第三透明电极311的尺寸小于所述第二透明电极310的尺寸。在另一实施例中，所述第三透明电极311的材料为氧化铟锡(ITO)。
在一实施例中，所述第二透明电极310可划分为第一区块3101与第二区块3102，所述第三透明电极311位于所述第二区块3102第一侧，且仅与所述第二区块3102重叠。
绝缘层312，位于所述第二透明电极310与第三透明电极311间，将第二透明电极310与第三透明电极311彼此隔离开。亦即，绝缘层312形成于第三透明电极311的第二表面，并完全覆盖第三透明电极311，至于所述第二透明电极310则是形成于绝缘层312第二表面。
液晶层32，位于第一基板30与第二基板31间，且填充于所述第一透明电极300与第二透明电极310间。液晶层31中除了液晶分子3200外，并掺杂了光致聚合分子3210。在一实施例中，当配向制程完成后，光致聚合分子3210会聚合于液晶层32的第二侧和第一侧，而分别形成第一聚合物层321与第二聚合物层322。如图3所示，第一聚合物层321，位于所述液晶层32第二侧，且位于所述第一透明电极300的第一表面；第二聚合物层322，位于所述液晶层32第一侧，且位于所述第二透明电极310第二表面。至于，液晶分子3200则会排列于第一聚合物层321与第二聚合物层322间，构成一液晶分子层320。
在一实施例中，所述显示面板3，更包含第一配向膜302与第二配向膜313。第一配向膜302，位于所述第一透明电极300的第一表面。第二配向膜313，位于所述第二透明电极310的第二表面。
在另一实施例中，所述显示面板3，更包括第一数据线，耦接于所述第二透明电极310，以及第二数据线，耦接于所述第三透明电极311。有关第 一数据线与第二数据线的具体描述，请参见下述图4a与图4b的相关描述。
请参考图4a与图4b，图4a是本申请第二透明电极的俯视图；图4b是本申请第三透明电极的俯视图。
如图4a所示，第二透明电极310为一像素电极，可划分为第一侧的第一区块3101与第二侧的第二区块3102。一闸极线40横向跨过第二透明电极310，且位于第一区块3101与第二区块3102间。一薄膜晶体管43，耦接于闸极线40，位于第二透明电极310的中央，且位于第一区块3101与第二区块3102间。所述薄膜晶体管43包括第一极431与第二极432。其中，第二极432经由接触点44电性连接第二透明电极310的第二区块3102。此外，第二极432亦经由接触点45电性连接第二透明电极310的第一区块3101。第一数据线41直向沿伸于所述第二透明电极310的左侧，并连接于所述薄膜晶体管43的第一极431。第二数据线42则直向沿伸于第二透明电极310的右侧。
当闸极线40上的闸极信号导通所述薄膜晶体管43时，第一数据线41的第一数据信号，会经由导通的第一极431与第二极432，传送至接触点44，并经由接触点44传送至第二透明电极310的第二区块3102。此外，第一数据线41的第一数据信号，亦会经由导通的第一极431与第二极432，传送至接触点45，并经由接触点45传送至第二透明电极310的第一区块3101。
在一实施例中，第二透明电极310的第一区块3101具有鱼骨图案。第一区块3101包含环绕周围的边框3101a、中央垂直沿伸的主干3101b、中央水平沿伸的主干3101c、以及与X轴夹角为±45度，±135度的四组分支部3101d组成。垂直主干3101b和水平主干3101c将一像素的面积平均分成四个区域，每个区域包括了斜向沿伸的分支部3101d平铺组成。分支部3101d的产生，是因为在第一区块3101的四个区域中分别形成了多个镂空的长条形开口，这些长条形的开口沿伸的方向，随着区域的不同，分别与X轴夹角为±45度，±135度。如此，整个第一区块3101在边框3101a中，会形成了上下和左右分别镜像对称的鱼骨图案结构。由于在第一区块3101上的液晶分子会分别沿着四组分支部3101d的角度分布，因此在不同的方向上观看时，会有补偿色偏的作用。
在一实施例中，第二透明电极310的第二区块3102具有鱼骨图案。第二区块3102包含环绕周围的边框3102a、中央垂直沿伸的主干3102b、中央 水平沿伸的主干3102c、以及与X轴夹角为±45度，±135度的四组分支部3102d组成。垂直主干3102b和水平主干3102c将一像素的面积平均分成四个区域，每个区域包括了斜向沿伸的分支部3102d平铺组成。分支部3102d的产生，是因为在第二区块3102的四个区域中分别形成了多个镂空的长条形开口，这些长条形的开口沿伸的方向，随着区域的不同，分别与X轴夹角为±45度，±135度。如此，整个第二区块3102在边框3102a中，会形成了上下和左右分别镜像对称的鱼骨图案结构。由于在第二区块3102上的液晶分子会分别沿着四组分支部3102d的角度分布，因此在不同的方向上观看时，会有补偿色偏的作用。
如图4b所示，第三透明电极311制作于闸极线40的第二侧。亦即第三透明电极311会与图4a中第二透明电极310的第二区块3102彼此重叠。一薄膜晶体管46，耦接于闸极线40。所述薄膜晶体管46包括第一极461与第二极462。其中，第二极462经由接触点47电性连接第三透明电极311。第一数据线41直向沿伸于所述第三透明电极311的左侧。第二数据线42则直向沿伸于第三透明电极311的右侧，并连接于所述薄膜晶体管46的第一极461。
当闸极线40上的闸极信号导通所述薄膜晶体管46时，第二数据线42的第二数据信号会经由导通的第一极461与第二极462，传送至接触点47，并经由接触点47传送至第三透明电极311。
图5是本申请一种显示面板的显示方法的方法流程图。所述显示面板的显示方法，可适用于上述图3、图4a与图4b中的显示面板3。所述显示面板的显示方法至少包含下述步骤:步骤S51，经由所述第一数据线41，输入第一数据信号至所述第二透明电极310。步骤S52，经由所述第二数据线42，输入第二数据信号至所述第三透明电极311。步骤S53，维持所述输入第一数据信号与所述输入第二数据信号的状态，对所述显示面板3进行光照处理，使所述液晶层32中的光致聚合分子3210，在所述第一透明电极300第一表面以及所述第二透明电极310第二表面发生聚合。步骤S54，当所述光致聚合分子3210聚合完毕，停止输入所述第一数据信号与所述第二数据信号。
在一实施例中，所述光照处理所用的光线为紫外光。并且，由于光致聚合分子3210会在第一透明电极300第一表面以及第二透明电极310第二表面分别发生聚合，因此当光致聚合分子聚合完毕，如图3所示，会在第一透 明电极300第一表面形成第一聚合物层321，并且在第二透明电极310第二表面形成第二聚合物层322。
此外，由于第二透明电极310与第三透明电极311是分别连接至不同的两条数据线，即第一数据线41与第二数据线42，所以在进行上述显示面板的显示方法时，第一数据线41与第二数据线42可以分别输入相同电压或不同电压的第一数据信号与第二数据信号。对于第二透明电极310的第二区块3102而言，由于其第一侧有第三透明电极311，因此第二区块3102第二侧的区域电场将会增强。至于，未与第三透明电极311重叠的第一区块3101，其第二侧的区域电场则未增强。换言之，在第二透明电极310与第一透明电极300间会形成不同的两个电场，而可在配向过程中产生相异的预倾角。亦即，位于第二区块3102第二侧的液晶分子3200，与位于第一区块3101第二侧的液晶分子3200，会具有相异的预倾角。
在一实施例中，由于第三透明电极311与第二数据线42的设计，是要在配向过程中额外增强区域电场，因此在液晶分子预倾角形成后，便不再给第二数据线42传送数据信号。亦即，后续当显示面板3工作时，只有第一数据线41会输入数据信号至第二透明电极310，因此在第二透明电极310与第一透明电极300间只有一个电场作用。
图6是本申请另一实施例中所提供一种显示面板的显示方法的方法流程图。所述显示面板的显示方法，可适用于上述图3、图4a与图4b中的显示面板3，且至少包含下列步骤。首先，进行步骤S61，提供一显示面板3，所述显示面板3包括第一基板30、液晶层32与第二基板31，其中所述液晶层32位于所述第一基板30与所述第二基板31间，所述第一基板30第一侧具有第一透明电极300，所述第二基板31第二侧具有第二透明电极310与第三透明电极311，所述第三透明电极311位于所述第二透明电极310第一侧，并且与部份所述第二透明电极310重叠。接着，进行步骤S62，经由第一数据线41，持续输入第一数据信号至所述第二透明电极310。再进行步骤S63，经由第二数据线42，持续输入第二数据信号至所述第三透明电极311。随后，进行步骤S64，对所述显示面板3进行光照处理，使所述液晶层32中的光致聚合分子3210发生聚合。最，进行步骤S65，当所述光致聚合分子3210聚合完毕，停止输入所述第一数据信号与所述第二数据信号。
在一实施例中，所述第二透明电极310与所述第三透明电极311重叠的 区域，相较于所述第二透明电极310未与所述第三透明电极311重叠的区域，具有较强的电场。由于第二透明电极310第二侧会产生两种不同强度的电场，因此可使液晶分子3200在配向过程后，分别具有两种相异的预倾角。
本申请提出一种新的显示面板和显示面板的显示方法，透过在像素电极与公共电极间产生两种不同的电场，使聚合物层在不同区域中具有不同的配向，而形成相异的预倾角。由此，液晶层中的液晶分子，由于聚合物层的作用，可以同时有两个相异的预倾角，从而使显示面板在显示时所产生的色偏得以改善。
以上所述，仅是本申请的可选实施例而已，并非对本申请作任何形式上的限制，虽然本申请已以可选实施例揭露如上，然而并非用以限定本申请,任何熟悉本专业的技术人员,在不脱离本申请技术方案范围内，当可利用上述揭示的方法及技术内容作出些许的更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
