  • the liquid crystal display mainly uses the optical characteristics of the liquid crystal to realize the display. Since the driving voltage of the liquid crystal molecules cannot be fixed at a certain value, the liquid crystal molecules are liable to be polarized, and the optical rotation characteristics are gradually lost. Therefore, in order to prevent the characteristics of the liquid crystal molecules from being broken, the liquid crystal panel is usually driven by the polarity inversion method. At this time, the driving voltage of the pixel electrodes on the liquid crystal display panel is divided into two polarities. Wherein, when the driving voltage on the pixel electrode is higher than the voltage of the common electrode, it is positive polarity, and when the driving voltage on the pixel electrode is lower than the voltage of the common electrode, it is negative polarity. Regardless of whether the driving voltage of the pixel electrode is positive or negative, the absolute value of the voltage difference with the common electrode is fixed, so the gray scale expressed is exactly the same.

Description

一种液晶显示面板及其驱动电路
【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示面板及其驱动电路。
【背景技术】
液晶显示器具有轻薄、无闪烁、能耗小等优点，是目前主流的显示器。
液晶显示器主要是利用液晶的光学特性实现显示。由于液晶分子的驱动电压不能固定在某一个值不变，否则液晶分子容易发生极化现象，从而逐渐失去旋光特性。因此，为了避免液晶分子的特性遭到破坏，通常采用极性反转方式对液晶面板进行驱动，此时，液晶显示面板上的像素电极的驱动电压则分成了两种极性。其中，像素电极上的驱动电压高于公共电极的电压时为正极性，像素电极上的驱动电压低于公共电极的电压时为负极性。无论像素电极的驱动电压为正极性还是负极性，其与公共电极的压差绝对值都是固定的，因此所表现出来的灰阶是一模一样。
在液晶的极性反转驱动方式中，通常有点反转、行反转、列反转和帧反转。其中，与其他反转方式相比，列反转方式具有低功耗和低闪烁度的优点，因此广泛应用于大部分的液晶显示器。列反转驱动方式中，在一个画面帧里，同一列子像素的驱动电压极性相同，相邻列子像素的驱动电压极性相反。此外，为了提高亮度，通常在原有的RGB三子像素上增加多一个W（白）子像素。因此，如图1所示，在RGBW像素结构的列反转驱动方式中，RGBW四子像素的驱动电压极性排列方式通常是正极性、负极性、负极性、正极性。其中，每个源极驱动器11对应一组RGBW四子像素，用于对一组RGBW四子像素提供驱动电压。
然而，在上述驱动方式中，由于RGBW四子像素的驱动电压有正极性电压也有负极性电压，因此源极驱动器11需要在正极性电压和负极性电压之间做来回切换，如此一来将会增加源极驱动器11的功耗。

【具体实施方式】
下面将结合附图和实施方式对本发明进行详细说明。
参阅图2，本发明液晶显示面板一实施方式中，液晶显示面板包括多个源极驱动电路21和多个子像素行22。多个源极驱动电路21设置在液晶显示面板的非显示区域，用于提供子像素的驱动电压。多个子像素行22沿列方向排列以形成多个子像素列，其位于液晶显示面板的显示区域，用于实现画面显示。
本实施方式中，每个子像素行22包括沿行方向周期性排列的不同颜色的多个子像素。每个子像素由一条数据线和一条扫描线所定义，一个子像素行与一条扫描线连接，一个子像素列与一条数据线连接。本实施方式中，每一子像素行22包括沿行方向周期性排列的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W。第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W分别为红色子像素、蓝色子像素、绿色子像素以及白色子像素。当然，第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W还可以分别为红色子像素、蓝色子像素、绿色子像素以及黄色子像素，或者其他颜色的子像素。
其中，在同一扫描帧内，其中两个基色子像素和另两个基色子像素的驱动电压极性相反，以实现列反转驱动。具体地，在一个扫描帧内，同一排列周期内的第一基色子像素R和第四基色子像素W的驱动电压极性相同，第二基色子像素G和第三基色子像素B的驱动电压极性相同，而第一基色子像素R、第四基色子像素W的驱动电压的极性和第二基色子像素G和第三基色子像素B的驱动电压的极性相反。所述一个扫描帧是指扫描一个子像素行的时间。
此外，在同一扫描帧内，每一排列周期内的各基色子像素上的驱动电压极性与相邻排列周期内的对应颜色的基色子像素上的驱动电压极性相反。
以图2所示的液晶显示面板为例，在一个扫描帧内，从左边起第一个排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性分别为正极性、负极性、负极性、正极性，而与第一个排列周期相邻的第二排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性分别为负极性、正极性、正极性、负极性。当完成一次所有子像素行的扫描后，即在一个画面帧里，一个排列周期内的第一个子像素列（第一基色子像素R所在列）上的驱动电压和第四子像素列（第四基色子像素W所在列）上的驱动电压极性相同，第二个子像素列（第二基色子像素G所在列）上的驱动电压和第一个子像素列上的驱动电压极性相反，第二个子像素列与第三个子像素列（第三基色子像素B所在列）上的驱动电压极性相同。
另外，当完成一次所有子像素行的扫描后，在下一次扫描中，在一个扫描帧内，从左边起第一个排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性变为负极性、正极性、正极性、负极性，与上一次扫描时的极性相反；而与第一个排列周期相邻的第二排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性变为正极性、负极性、负极性、正极性，与上一次扫描时的极性相反。由此，实现列反转驱动。
通过上述极性反转的驱动方式，能够减小信号串扰，降低画面闪烁度。当然，在他实施方式中，相邻两个排列周期内的同种颜色的子像素上的驱动电压极性也可以相同。
本实施方式中，每个源极驱动电路21设有四个输出端口211，与每一排列周期内的子像素的数量相同。其中，可以根据每一排列周期内的各子像素上所需的驱动电压的极性对源极驱动电路的各个输出端口进行布线。
具体地，每个源极驱动电路21的四个输出端口211分别连接在同一扫描帧内驱动电压极性相同的四个基色子像素以对该四个基色子像素提供相同极性的驱动电压。进一步地，每个源极驱动电路21用于获取相邻两个排列周期内在同一扫描帧内驱动电压极性相同的四个基色子像素所分别对应的电压数据，并通过四个输出端口211输出，其四个输出端口211分别连接相邻两个排列周期内在同一扫描帧内驱动电压极性相同的四个基色子像素。
如图2所示，从左边起第一个源极驱动电路21的其中两个输出端口211分别连接第一个排列周期内的第一基色子像素R和第四基色子像素W，另两个输出端口211分别连接与第一个排列周期相邻的第二个排列周期内的第二基色子像素G和第三基色子像素B，以对该四个基色子像素施加相同极性的驱动电压。第二个源极驱动电路21的其中两个输出端口21分别连接第二排列周期内的第一基色子像素R和第四基色子像素W，另两个输出端口21分别连接与第二排列周期相邻的第一排列周期内的第二基色子像素G和第三基色子像素B，以对该四个基色子像素提供相同极性的驱动电压。对于剩余的源极驱动电路的输出端口和各排列周期内的子像素的连接关系可依此类推，在此不进行一一赘述。
需要说明的是，本实施方式所述的输出端口连接子像素是指输出端口与相应子像素所对应的数据线连接，以通过数据线对子像素施加驱动电压。并且，每个输出端口是连接一条数据线，以对与该条数据线连接的一列子像素提供驱动电压。
由此，在同一个扫描帧内，每个源极驱动电路21的四个输出端口211所输出的驱动电压的极性均相同，与现有的驱动方式相比，在一个扫描帧内源极驱动电路21只需输出同一种极性的驱动电压，而不需要在正极性驱动电压和负极性驱动电压之间来回切换，减少了电压变换范围，从而能够进一步降低源极驱动电路的功耗。
参阅图3，本发明液晶显示面板的实施方式中，液晶显示面板进一步还包括转换电路23和四条控制线S1~S4。每个所述源极驱动电路21包括数据处理单元212、源极IC芯片213以及四个开关元件Q1~Q4。
其中，转换电路23、四条控制线S1~S4以及源极驱动电路21可以是在T-Con中，也可以设置在T-Con外。
转换电路23用于将输入的多组原始RGB三基色电压数据转换为多组RGBW四基色电压数据，一组（即一个排列周期内）第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W对应一组RGBW四基色电压数据。数据处理单元212与转换电路23连接，用于获取相邻两个排列周期内在同一扫描帧内驱动电压极性相同的子像素所分别对应的电压数据。如图3所示，从左起第一个源极驱动电路21的数据处理单元212用于获取在一个扫描帧内驱动电压极性相同的第一排列周期内的第一基色子像素R、第四基色子像素W以及第二排列周期内的第二基色子像素G、第三基色子像素B所分别对应的电压数据，然后将获取的电压数据输出至源极IC芯片213，其他源极驱动电路的数据处理单元可依此类推。由此，可使得每个源极驱动电路21都能够输出正确的电压数据。
源极IC芯片213包括输入端和输出端，开关元件包括输入端、输出端以及控制端。源极IC芯片的输入端连接数据处理单元212，输出端连接四个开关元件Q1~Q4的输入端。四个开关元件Q1~Q4的输出端分别连接源极驱动电路21的四个输出端口211，四个开关元件Q1~Q4的控制端分别连接四条控制线S1~S4。四条控制线S1~S4用于控制四个开关元件Q1~Q4的导通和关闭，当四个开关元件Q1~Q4导通时，源极IC芯片213可将电压数据通过开关元件输出至相应的子像素。
通过本发明液晶显示面板的实施方式，不仅能够实现子像素的列反转驱动，从而降低画面闪烁，同时能够进一步降低源极驱动电路21的功耗。
参阅图4，在本发明液晶显示面板的另一实施方式中，与图3所示的实施方式不同的是，本实施方式中，同一排列周期内相邻两个子像素的驱动电压极性相反，而相邻两个排列周期内的同种颜色的子像素的驱动电压极性相同。具体地，在同一排列周期内的第一基色子像素R和第三基色子像素B的驱动电压极性相同，第二基色子像素G和第四基色子像素W的驱动电压极性相同，而第一基色子像素R和第二基色子像素G的驱动电压极性相反。而相邻两个排列周期内的第一基色子像素R的驱动电压极性相同，以此类推相邻两个排列周期内的其他基色子像素的驱动电压极性。
如图4所示，在一个扫描帧内，从左起第一个排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性分别为正极性、负极性、正极性、负极性，而与第一个排列周期相邻的第二排列周期内的第一基色子像素R、第二基色子像素G、第三基色子像素B以及第四基色子像素W的驱动电压的极性分别为正极性、负极性、正极性、负极性。
在本实施方式中，每个源极驱动电路21的四个输出端口分别连接相邻两个排列周期内的第一基色子像素R和第三基色子像素B，或者分别连接相邻两个排列周期内的第二基色子像素G和第四基色子像素W。以图4为例，从左起第一个源极驱动电路21的四个输出端口分别连接第一排列周期内的第一基色子像素R和第三基色子像素B，以及第二排列周期内的第一基色子像素R和第三基色子像素B，以对该四个子像素施加极性相同的驱动电压。第二个源极驱动电路21的四个输出端口分别连接第一排列周期内的第二基色子像素G和第四基色子像素W，以及第二排列周期内的第二基色子像素G和第四基色子像素W，以对该四个子像素施加极性相同的驱动电压。
其中，在上述图2-4所示的实施例中，相邻子像素行中的一个排列周期内的对应子像素的颜色相同，即相邻子像素行的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素均是分别为红色子像素、绿色子像素、蓝色子像素以及白色子像素，每一个子像素列均为同一种颜色的子像素。在他实施方式中，相邻两个子像素行中的一个排列周期内的对应子像素的颜色也可以不相同，如图5所示，第一个子像素行52-1的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别为红色子像素、绿色子像素、蓝色子像素以及白色子像素，第二个子像素行52-2的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别绿色子像素、蓝色子像素、白色子像素以及红色子像素，第三个子像素行52-3的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别蓝色子像素、白色子像素、红色子像素以及绿色子像素，第四个子像素行52-4的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别白色子像素、红色子像素、绿色子像素以及蓝色子像素，每四个子像素行为一个循环周期。由此，在一个子像素列中包括四种颜色的子像素。
当然，在一个子像素列中也可以包括两种颜色的子像素。参阅图6，图6所示的子像素排列方式中，第一个子像素列62-1的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别为红色子像素、绿色子像素、蓝色子像素以及白色子像素，第二个子像素行62-2的一个排列周期内的第一基色子像素、第二基色子像素、第三基色子像素、第四基色子像素分别蓝色子像素、白色子像素、红色子像素以及绿色子像素，每两个子像素行为一个循环周期。
虽然图5和图6所示的子像素排列方式与图2-4的子像素排列方式有所不同，但是同样可以采用如图2-4所示的驱动电路进行驱动，以达到降低功耗的目的。
在本发明液晶显示面板的其他实施方式中，每一排列周期内的子像素的数量还可以是两个或三个，或者更多个，并且每一排列周期内也可以是仅有一个子像素的驱动电压的极性与其他子像素的驱动电压的极性相反，例如一个排列周期内的其中一个子像素的驱动电压极性为正极性，该排列周期内的子像素的驱动电压均为负极性。此外，每个源极驱动电路的输出端口的数量还可以是两个或三个，或者更多个，只需使每个源极驱动电路的所有输出端口均连接在同一扫描帧内驱动电压极性相同的子像素即可。
本发明还提供一种液晶显示面板的驱动电路的实施方式，所述驱动电路包括如前述任一实施方式所述的源极驱动电路。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
