Description

液晶显示装置 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装置。
背景技术
液晶显示器(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器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(Color Filter，CF)基板之间灌入液晶分子，并在两片基板上分别施加像素电压和公共电压，通过像素电压和公共电压之间形成的电场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反转液晶分子，防止液晶分子固定偏向同一个方向而失去活性。目前，液晶显示面板支持多种反转模式，比如点反转模式、行反转模式、列反转模式等，实现反转的途径主要是通过不断交替TFT源极电压的正、负极性(即像素电压的正、负极性)，或不断交替公共电压的正、负极性，以达到交流驱动的目的。其中，当像素电极的电压高于公共电极电压时，就称之为正极性像素电极。而当像素电极的电压低于公共电极的电压时，就称之为负极性像素电极，不管是正极性或是负极性，当像素电极和公共电极之间的压差固定时，所显示的灰阶都是相同的。
在现有液晶显示面板中，为抑制闪烁，通常使用列反转的方式进行驱动，并且由于现有技术中的公共电极通常一块覆盖整个显示区的连续的平面结构，因此当公共电压(Vcom)采用交流电压时，无法实现列反转驱动，故而现有的列反转方式驱动的液晶显示面板的公共电压(Vcom)只能采用固定的电压值的直流电压，并通过变更像素电压的大小，来实现交流驱动，但在这种方式下，假设某一灰阶的正极性像素电压为V正，负极性像素电压 为V负，正极性像素电压与公共电压Vcom之间的压差△V为V正-Vcom，负极性像素电压与公共电压Vcom之间的压差△V为Vcom-V负，列反转时，正极性像素电压转换到负极性像素电压之间的差值为2△V，从而导致列反转时正极性像素电压与负极性像素电压之间的差值很大，液晶显示面板的功耗较高。

具体地，所述信号接入板2包括：多个信号输出端201，每一个信号输出端201均对应电性连接一条金属连接线12。
值得一提的是，所述金属连接线12的材料为低电阻率的金属，例如铜，通过金属连接线12连接公共电极条14和信号接入板2，相比于将公共电极条14直接与信号接入板2相连，能够减小因公共电极条14的电阻率太大而出现的电压延迟(delay)问题，优选地，所述公共电极条14的材料为ITO。所述第一绝缘层13的材料为氧化硅和氮化硅中的一种或二者的组合。
需要说明的是，如图4所示，本发明的第一实施例在列反转驱动时的具体工作过程为：首先，所述液晶显示面板显示一帧画面，所述数据线为各个向像素电极24提供像素电压(V0～V255)，其中，同一列像素电极24上的像素电压的极性相同，相邻的两列像素电极24上的像素电压的极性相反，同时所述信号接入板2为各个公共电极条14提供公共电压Vcom，其中，对应于施加有正极性的像素电压的像素电极24的公共电极条14的公共电压Vcom的电压值为第一电压值Vcom1，对应于施加有负极性的像素电压的像素电极24的公共电极条14的公共电压Vcom的电压值为第二电压值Vcom2。接着，所述液晶显示面板显示下一帧画面同时进行列反转，使得同一个像素电极24上的像素电压的极性与所述上一帧相反，同时各个公共电极条14上的公共电压Vcom也相应变化，保证对应于施加有正极性的像素电压的像素电极24的公共电极条14的公共电压Vcom的电压值始终为第一电压值Vcom1，对应于施加有负极性的像素电压的像素电极24的公共电极条14的公共电压Vcom的电压值始终为第二电压值Vcom2。在该两帧画面中，假设某一灰阶的正极性像素电压为V正，负极性像素电压为V负，则该灰阶的正极性像素电压与公共电压之间的压差△V为V正-Vcom1，负极性像素电压与公共电压之间的压差△V为Vcom2-V负，列反转时，该灰阶的正极性像素电压转换到负极性像素电压之间的差值为2△V- (Vcom2-Vcom1)，即在采用交流的公共电压驱动时，正极性像素电压与负极性像素电压之间的差值相对于现有技术减少了公共电压Vcom交流变化的差值。从而，本发明的液晶显示装置，能够同时实现液晶显示装置的列反转和公共电压交流驱动，减小列反转模式下，液晶显示装置的正极性像素电压与负极性像素电压之间的压差，降低液晶显示装置的功耗。
请参阅图1和图3，本发明的第二实施例提供一种液晶显示装置，该第二实施例与第一实施例的区别在于，所述第二实施例采用彩色滤光片整合于阵列基板(Color filter On Array，COA)技术，即在本发明的第二实施例中，所述色阻层17设于所述第二基板20中，具体为所述色阻层17位于所述第二绝缘层23和像素电极24之间，其余均与所述第一实施例相同，此处不再赘述。
值得一提的是，在本发明的第一实施例中，每一个公共电极条14均通过一贯穿所述第一绝缘层13和色阻层17的过孔18与所述金属连接线12电性连接。在本发明的第二实施例中，每一个公共电极条14均通过一贯穿所述第一绝缘层13的过孔18与所述金属连接线12电性连接。
综上所述，本发明提供了一种液晶显示装置，该液晶显示装置通过将公共电极设置为多个平行间隔排列的公共电极条，并在每一个公共电极条下方设置连接该公共电极条和信号接入板的金属连接线，通过金属连接线将信号接入板产生的交流的公共电压接入到公共电极条上，从而使得所述液晶显示装置在列反转时，公共电压也会不断变化，能够同时实现液晶显示装置的列反转和公共电压交流驱动，并降低液晶显示装置的功耗。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
