Description

液晶显示面板及其驱动方法 技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示面板及其驱动方法。
 背景技术
液晶显示装置（Liquid Crystal Display，LCD）具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，如：液晶电视、移动电话、个人数字助理（PDA）、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。
现有市场上的液晶显示装置大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在薄膜晶体管基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩色滤光片基板（Color Filter，CF）之间灌入液晶分子，并在两片基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
液晶显示面板包括多个呈阵列式排布的像素，每个像素电性连接一个薄膜晶体管（TFT），该TFT的栅极（Gate）连接至水平扫描线，漏极（Drain）连接至竖直方向的数据线，源极（Source）则连接至像素电极。在水平扫描线上施加足够的电压，会使得电性连接至该条扫描线上的所有TFT打开，从而数据线上的信号电压能够写入像素，控制液晶的透光度，实现显示效果。
高分辨率和高刷新频率是目前高端液晶显示装置产品的发展趋势，高分辨率能显示更丰富的画面细节，使画质更加真实无颗粒感，高刷新频率达到能满足动态显示的需求，保证画面足够流畅。高分辨率和高扫描频率的显示器TFT充电时间非常短，对于迁移率只有0.5cm 2/Vs 的非晶硅（a-Si）产品来说，在常规电路架构下没有办法完成充电过程。
为了增加TFT的充电时间，现有技术提出了一种两行扫描线同时扫描的技术，该技术能够将TFT的充电时间增加一倍，应用到分辨率为8K刷新频率为120Hz的液晶显示面板中，可以将每个TFT充电时间增加到3.86μs，足以完成每个TFT的充电需求，但将该技术应用在分辨率为8K刷新频率为144Hz的液晶显示面板时，每个TFT充电时间仍仅有3.2μs，充电时间依然很短，像素单元无法及时充饱电荷，因充电能力不足可能会导致显示不良及可靠性问题。

图3为本发明的液晶显示面板的驱动方法的流程图。
 本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图1，本发明提供一种液晶显示面板，包括：多个像素单元10、多条扫描线20及多条数据线30；
所述多个像素单元10阵列排布，对应每一行像素单元10设置沿行方向延伸且电性连接该行像素单元10的一条扫描线20；
对应每一列像素单元10设置沿列方向延伸三条数据线30，每连续排列的三行像素单元10为一个像素单元组101，电性连接同一个像素单元组的三条扫描线20为一个扫描线组201，在同一列像素单元10中，同一个像素单元组101中的三个像素单元10分别电性连接对应该列像素单元10设置的三条数据线30；
扫描驱动时，各个扫描线组201依次开启，对各个像素单元组101依次扫描，同一个扫描线组201中的三条扫描线20同时开启。
举例来说，在本发明的一些实施例中，所述液晶显示面板在驱动时，第一至第三扫描线20先打开，各条数据线30输出数据信号，对第一至第三行像素单元10进行充电，然后第四至第六行扫描线20再打开，各条数据线30输出数据信号，对第四至第六行像素单元10进行充电，接着第七至第九行扫描线20再打开，各条数据线30输出数据信号，对第七至第九行像素单元10进行充电，按此规律充电直至最后一行。
具体地，在本发明的一些实施例中，该液晶显示面板的分辨率为8K，刷新频率为144Hz。
需要说明的是，在8K 120Hz液晶显示面板中，通过对应每一列像素单元10设置三条数据线30，在驱动时通过三条扫描线20同时开启进行扫描，能够将每条扫描线20的实际开启时间延长至3×（1/144HZ）/4320=4.8μs，相比于现有技术，每条扫描线20的实际开启时间明显延长，各个像素单元10的充电时间也明显延长使得，每个像素单元10均有足够的时间充电至饱和，能够避免充电不足引起的显示不良，提升显示面板的稳定性。
具体地，在本发明的一些实施例中，结合图2，对应每一列像素单元设置的三条数据线30分别为第一数据线31、第二数据线32及第三数据线33，所述第一数据线31及第三数据线33分别位于该列像素单元10的两侧，所述第二数据线32位于该列像素单元10的中央。
进一步地，每一个像素单元10均包括一开关薄膜晶体管11及一像素电极21；所述开关薄膜晶体管的栅极电性连接该像素单元10对应的扫描线20，源极电性连接该像素单元10对应的数据线30，漏极电性连接其所在像素单元10中的像素电极21；
进一步地，所述像素电极21为米字形结构的像素电极，所述像素电极21包括主干电极211以及分别向四个不同方向延伸的多个第一电极分支212、多个第二电极分支213、多个第三电极分支214和多个第四电极分支215，所述第一电极分支212、第二电极分支213、第三电极分支214、第四电极分支215均与所述主干电极211相连；
所述主干电极211包括沿列方向延伸的第一主干2111以及沿行方向延伸第二主干2112，所述第一主干2111与第二主干2112交叉限定出四个畴，所述第一电极分支212、第二电极分支213第三电极分支214及第四电极分支215分别位于所述四个畴中；
每一条第二数据线32均正对其所对应的一列像素单元20的像素电极21的第一主干2111设置。
需要说明的是，在米字形的像素电极中对应主干电极211的区域为各个像素电极的暗纹区域，其对应的区域的驱动电压较小，透光率较低，因此，本发明通过将每一条第二数据线32均正对其所对应的一列像素单元20的像素电极21的第一主干2111设置，能够在实现三行扫描线20同时扫描的同时，最大程度的减少因数据线30的数量的增加而导致像素单元10的开口率的下降，保证显示效果。
具体地，所述数据线30用于向各个像素单元10输出数据信号，在液晶显示面板中，液晶分子具有一种特性，如果长时间给液晶分子施加同向电压，会使液晶分子极化，即使将电压取消，液晶分子亦会因为特性的破坏而无法再因电场的变化而转动，因此液晶显示面板必须是通过交流驱动，在显示画面时的时候以一定的频率去翻转液晶分子，防止液晶分子固定偏向同一个方向而失去活性，基于此，本发明的液晶显示面板还设置，在一帧画面时间内，相邻的两条数据线30输出的数据信号的极性相反，在相邻的两帧画面时间内，同一条数据线30输出的数据信号的极性相反，以实现液晶分子的有效驱动。
结合图2所示的实施例，在一帧画面时间内，同一列像素单元10的极性按照两正一负的次序重复排列。
