Description

一种液晶显示器 【技术领域】
本发明涉及显示技术领域，具体而言涉及一种液晶显示器。
【背景技术】
液晶显示器具有功耗低、辐射低及制作成本低等特点，现已广泛应用于各种电子设备中，如电视、手机、相机或穿戴设备。其中TFT-LCD(Thin Film Transistor Liquid Crystal Display，薄膜晶体管液晶显示器)的四色RGBW显示技术因具有高透光率和高亮度而受到市场欢迎。
目前，液晶显示器在驱动液晶分子偏转以显示画面灰阶时，通常采用正、负极性反转方式，常见的子像素阵列极性反转方式为点反转或列反转。但是现有相邻列数据线输出的数据信号极性相反，使得施加到对应相邻列子像素的极性也相反，这在四色RGBW显示时，由于数据信号的瞬时变化(Data transient)使得公共电极耦合(Vcom Coupling)严重，同时也因为相同颜色的子像素极性可能相同而产生严重的闪烁(flick)现象，进而影响液晶显示器显示画面的品质。
综上，现有相邻列数据线输出的数据信号极性相反的技术不能满足四色RGBW液晶显示器对显示画面品质的要求。

【附图说明】
图1是本发明一实施例的液晶显示器的像素结构示意图；
图2是图1所示的液晶显示器显示纯红色画面帧时的数据信号的时序示意图；
图3是本发明另一实施例的液晶显示器的像素结构示意图；
图4是图3所示的液晶显示器显示纯红色画面帧时的数据信号的时序示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明所提供的示例性的实施例的技术方案进行清楚、完整地描述。
图1是本发明一实施例的液晶显示器的像素结构示意图。如图1所示，该液晶显示器10包括沿行方向和列方向阵列式排布的多个子像素110以及沿列方向设置的多条数据线、沿行方向设置的多条扫描线，多条数据线用于分别向对应列的子像素110施加数据信号，多条扫描线用于分别向对应行的子像素110施加扫描信号以开启每行子像素110并接收对应连接的数据线上的数据信号。图1中示例为液晶显示器10包括五行八列子像素110，以Gn表示第n行子像素110连接的扫描线，以Sn表示第n条数据线，n为正整数，每一行子像素110包括周期性排列的偶数种不同颜色的子像素110，其中当液晶显示器10显示纯色画面帧时，在沿行方向相邻设置的不同颜色的子像素110的偶数个排列周期内，同一颜色的子像素110中施加正极性数据信号的子像素110的数目与施加负极性数据信号的子像素110的数目相同。
再次参阅图1所示，偶数种不同颜色的子像素110为四种颜色的子像素110，分别为红光子像素(本说明书下文及说明书附图以R子像素表示)、绿光子像素(本说明书下文及说明书附图以G子像素表示)、蓝光子像素(本说明书下文及说明书附图以B子像素表示)以及白光子像素W(本说明书下文及说明书附图以W子像素表示)。其中，在沿行方向相邻设置的以R子像素、G子像素、B子像素和W子像素为周期排列的两个排列周期内，奇数行如第一行、第三行子像素110以R子像素、G子像素、B子像素和W子像素为周期排列，偶数行如第二行、第四行子像素110以W子像素、R子像素、G子像素和B子像素为周期排列，其中每条数据线连接对应的一列子像素110。当然，其他实施例可选奇数行以W子像素、R子像素、G子像素和B子像素且偶数行以R子像素、G子像素、B子像素和W子像素为周期排列。
在沿列方向相邻设置的两行子像素110中，同一颜色的子像素110沿行方向彼此错开一列或三列设置。例如图1所示，从左至右，位于第一行且第一列的R子像素和位于第二行且第二列的R子像素沿行方向彼此错开一列设置；位于第二行且第二列的R子像素和位于第三行且第五列的R子像素沿行方向彼此错开三列设置。
在沿列方向相邻设置的两行子像素110中，彼此错开一列的两个同一颜色的子像素110分别由两个同一颜色的子像素110之间的数据线施加数据信号，例如，第一行且第一列的R子像素和第二行且第二列的R子像素分别由第二条数据线S2施加数据信号。
进一步参阅图1所示，所述偶数个排列周期以两个排列周期为例，在两个排列周期中，第n个子像素110的数据信号极性与第n+4个子像素110施加的数据信号极性相反，其中n是大于或等于1且小于或等于4的正整数。例如，从左至右，第一条数据线S1、第二条数据线S2、第三条数据线S3、第四条数据线S4、第五条数据线S5、第六条数据线S6、第七条数据线S7和第八条数据线S8上的数据信号极性依次是正极性(+)、负极性(-)、正极性(+)、正极性(+)、负极性(-)、正极性(+)、负极性(-)和负极性(-)。
在沿行方向相邻设置的子像素110的两个排列周期内，每一排列周期 内的部分相邻子像素110上的数据信号的极性相同，且不同的排列周期内，部分相邻子像素110上的数据信号的极性相反。例如，第一行且第三列的B子像素和第一行且第四列的W子像素位于同一排列周期内且相邻，两者分别自第四条数据线S4和第五条数据线S5接收的数据信号的极性相同，第一行且第四列的W子像素和第一行且第五列的R子像素位于不同的排列周期内且相邻，两者分别自第五条数据线S5和第六条数据线S6接收的数据信号的极性相反。
在沿行方向相邻设置的以R子像素、G子像素、B子像素和W子像素为周期排列的两个排列周期内，第二条数据线S2与第六条数据线S6的数据信号极性相反，使得第一列的R子像素与第五列的R子像素的数据信号极性相反，从而满足同一颜色的R子像素中施加正极性数据信号的第一列的R子像素的数目与施加负极性数据信号的第五列的R子像素的数目相同。同理，第三条数据线S3与第七条数据线S7的数据信号极性相反，使得第二列的G子像素与第六列的G子像素的数据信号极性相反，从而满足同一颜色的G子像素中施加正极性数据信号的第六列的G子像素的数目与施加负极性数据信号的第二列的G子像素的数目相同；第四条数据线S4与第八条数据线S8的数据信号极性相反，使得第三列的B子像素与第七列的B子像素的数据信号极性相反，从而满足同一颜色的B子像素中施加正极性数据信号的第三列的B子像素的数目与施加负极性数据信号的第七列的B子像素的数目相同；第五条数据线S5与第一条数据线S1的数据信号极性相反，使得第四列的W子像素与第八列的W子像素的数据信号极性相反，从而满足同一颜色的W子像素中施加正极性数据信号的第八列的W子像素的数目与施加负极性数据信号的第四列的W子像素的数目相同。
在本实施例中，同一颜色的子像素110中施加正极性数据信号的子像素110的数目与施加负极性数据信号的子像素110的数目相同，即在液晶显示器10显示纯色画面时，相同颜色的子像素110的数据信号极性一半为正一半为负，从而在列反转或点反转驱动子像素110进行灰阶显示时，能够避免因数据信号的瞬时变化产生公共电极耦合，消除闪烁现象，提高液晶显示器10的显示画面品质。其中图1及本说明书下文均以列反转驱动方式为例进行说明。
图2是图1所示液晶显示器10显示纯红色画面帧时的数据信号的时序示意图。如图2所示，在液晶显示器10显示纯色画面帧时，每条数据线向对应列子像素110施加数据信号的时序图以第n条数据线Sn上施加数据信号Dn表示，其中数据信号Dn实质上是电信号，且电压大于子像素110的公共电极电压(Vcom)时为正极性，电压小于子像素110的公共电极电压时为负极性。具体地，在显示纯红色画面帧时，对于第二条数据线S2上的数据信号D2与第六条数据线S6的数据信号D6极性相反，使得第一列的R子像素上施加的数据信号D2与第五列的R子像素上施加的数据信号D6极性相反，由于其他条数据线对应显示其他颜色，因此其他条数据线施加的数据信号与公共电极Vcom相同，此时满足R子像素具有的数据信号极性一半为正，一半为负，避免了因数据信号的瞬时变化产生公共电极耦合信号，图2中以VC表示公共电极耦合信号，从而消除闪烁现象，并提高液晶显示器10的显示画面品质。同理在显示其他纯色如绿色、蓝色、白色或由上述颜色组成的任意颜色时，也满足R子像素、G子像素、B子像素或W子像素具有的数据信号极性一半为正，一半为负，避免因数据信号的瞬时变化产生公共电极耦合信号，从而消除闪烁现象，提高显示画面品质。
继续参阅图1，液晶显示器10还包括数据驱动器120和扫描驱动器130，扫描驱动器130包括数目与多条扫描线对应的多个充电端口，数据驱动器120包括数目与多条数据线对应的多个输出端口，图1中示例为五个充电端口和八个输出端口，以Ln表示第n个充电端口，每行子像素110对应的扫描线以直通方式连接充电端口，以Kn表示第n个输出端口，每一输出端口输出的数据信号与相邻的输出端口输出的数据信号极性相反。其中，在沿行方向相邻设置的不同颜色的子像素110的偶数个排列周期内，一部分子像素110对应的数据线以直通方式连接输出端口，另一部分子像素110对应的数据线以交叉方式连接输出端口。
所述直通方式为将多条扫描线中的第n条数据线Gn与扫描驱动器130的第n个充电端口Ln连接或将多个数据线中的第n条数据线Sn与数据驱动器120的第n个输出端口Kn连接，交叉方式为将多个数据线中的第i条数据线Si与数据驱动器120的第i+j个输出端口Ki+j或第i-j个输出端口Ki-j连接，其中n和i为互不相同的正整数，j为奇数。
例如图1所示的两个排列周期内，第一条数据线S1、第二条数据线S2、第三条数据线S3和第八条数据线S8采用直通方式分别连接输出端口K1，K2，K3和K8，第四条数据线S4、第五条数据线S5、第六条数据线S6和第七条数据线S7采用交叉方式分别连接输出端口K5，K4，K7和K6，此时j为1。应理解，其他实施例可选具有其他连接方式，同理可选不限于j是1的其他正奇数，可根据具体的排列周期设定数据线与输出端口的连接方式及j的具体数值，此处不做限制。
图3是本发明另一实施例的液晶显示器的像素结构示意图。如图3所示，该液晶显示器包括与图1所示的液晶显示器10基本相同的元件并由相同的附图标记进行标示，与上述实施例不同的是，在沿列方向相邻设置的两行子像素110中，彼此错开一列的两个同一颜色的子像素110分别由两个同一颜色的子像素110两侧的数据线施加数据信号，例如，从左至右，第一行且第一列的R子像素和第二行且第二列的R子像素彼此错开一列，第一行且第一列的R子像素由第一条数据线S1施加数据信号，第二行且第二列的R子像素由第三条数据线S3施加数据信号，第一条数据线S1和第三条数据线S3分别位于两个R子像素的两侧。
在沿行方向相邻设置的以R子像素、G子像素、B子像素和W子像素为周期排列的两个排列周期内，第一条数据线S1与第五条数据线S5的数据信号极性相反，使得第一列的R子像素与第五列的R子像素的数据信号极性相反，从而满足同一颜色的R子像素中施加正极性数据信号的第一列的R子像素的数目与施加负极性数据信号的第五列的R子像素的数目相同。同理，第二条数据线S2与第六条数据线S6的数据信号极性相反，使得第二列的G子像素与第六列的G子像素的数据信号极性相反，从而满足同一颜色的G子像素中施加正极性数据信号的第六列的G子像素的数目与施加负极性数据信号的第二列的G子像素的数目相同；第三条数据线S3与第七条数据线S7的数据信号极性相反，使得第三列的B子像素与第七列的B子像素的数据信号极性相反，从而满足同一颜色的B子像素中施加正极性数据信号的第三列的B子像素的数目与施加负极性数据信号的第七列的B子像素的数目相同；第四条数据线S4与第八条数据线S8的数据信号极性相反，使得第四列的W子像素与第八列的W子像素的数据信号极性相反，从而满 足同一颜色的W子像素中施加正极性数据信号的第八列的W子像素的数目与施加负极性数据信号的第四列的W子像素的数目相同。
图4是图3所示液晶显示器显示纯红色画面帧时的数据信号的时序示意图。如图3所示，在液晶显示器显示纯红色画面帧时，对于第一条数据线S1上的数据信号D1与第五条数据线S5的数据信号D5极性相反，使得第一列的R子像素上施加的数据信号D1与第五列的R子像素上施加的数据信号D5极性相反，且对于第三条数据线S3上的数据信号D3与第七条数据线S7的数据信号D7极性相反，使得第三列的R子像素上施加的数据信号D3与第七列的R子像素上施加的数据信号D7极性相反，由于其他条数据线对应显示其他颜色，因此其他条数据线施加的数据信号与公共电极Vcom相同，此时满足R子像素具有的数据信号极性一半为正，一半为负，避免了因数据信号的瞬时变化产生公共电极耦合信号，从而可消除闪烁现象，并提高液晶显示器10的显示画面品质。
应理解，以上所述仅为本发明的实施例，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，例如各实施例之间技术特征的相互结合，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。
