Description

一种液晶显示面板及装置 技术领域
本发明涉及显示器技术领域，特别是涉及一种液晶显示面板及装置。
 背景技术
液晶显示器是目前使用最广泛的一种平板显示器，被应用在各种电子设备如移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕中。
目前普遍采用的液晶显示器，通常由上下衬底和液晶层组成，衬底由玻璃和电极等组成。当上下衬底都设置电极时，可以形成纵向电场模式的显示器，如TN（Twist Nematic）模式、VA（Vertical Alignment）模式以及为了解决视角过窄开发的MVA（Multi-domain Vertical Alignment）。当仅在一侧的衬底上设置电极时，形成横向电场模式的显示器，如IPS（In-plane switching）模式和FFS（Fringe Field Switching）模式等。
图1和图2为现有液晶显示器常用的两种驱动架构，101-103分别表示红绿蓝像素，G1-G6表示扫描线，D1-D6表示数据线。对比图2和1，可见第二种驱动架构中数据线的数量为第一种驱动架构的数据线数量的1/3，因此第二种驱动架构的数据连接器的数量（Data COF）为第一种驱动架构中数据连接器数量的1/3，第二种驱动架构中扫描线的数量为第一种驱动架构中扫描线数量的3倍，第二种驱动架构的每个扫描信号的脉冲宽度和充电时间分别为第一种驱动架构中扫描信号的脉冲宽度和充电时间的1/3。
图3为第二种驱动架构显示单色画面的示意图，当显示单色画面（纯绿色）时，仅绿色像素对应的数据电压为高电平，红色和蓝色像素对应的数据电压为低电平，也即绿色像素显示绿色，红色和蓝色像素全黑显示。以第一列像素为例，其驱动信号的波形如图4所示，t1-t2、t4-t5分别表示第一列中第一个、第二个红色像素的数据电压，t2-t3、t5-t6表示第一列中第一个、第二个绿色像素的数据电压，t3-t4、t6-t7表示第一列中第一个、第二个蓝色像素的数据电压，图4仅给出一列像素的驱动波形，其中11表示外部提供的数据电压，也即初始数据电压，12表示实际的数据电压，由于数据线上的电压始终处于高低变化状态，导致出现重载画面，使得像素的充电能力很差，容易导致充电不足，造成画面显示不良，降低了显示质量。
因此，有必要提供一种液晶显示面板及装置，以解决现有技术所存在的问题。
 技术问题
本发明的目的在于提供一种液晶显示面板及装置，能够提高显示质量。
 技术解决方案
为解决上述技术问题，本发明提供一种液晶显示面板，其包括：
N条数据线、多条扫描线以及多个像素，相邻两个像素的颜色不同；每一行像素对应设置一扫描线，第n列像素对应第n条数据线和第n+1条数据线，所述第n条数据线和所述第n+1条数据线交替连接所述第n列像素中的像素，且所述第n+1条数据线连续驱动两个同种颜色的像素；当所述液晶显示面板显示单一颜色的画面时，每一列对应颜色的像素的数据电压为高电平，其中N≥2，0＜n＜N。
在本发明的液晶显示面板中，所述第n+1条数据线与所述第n+1列像素的偶数行像素连接，且与第n列像素的奇数行像素连接。
在本发明的液晶显示面板中，所述第n+1条数据线与所述第n+1列像素的奇数行像素连接，且与第n列像素的偶数行像素连接。
在本发明的液晶显示面板中，所述第n+1条数据线连续驱动位于第n列和第n+1列的两个同种颜色的像素。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图5-8，图5为本发明液晶显示面板的驱动架构图。
如图5所示，本实施例的液晶显示面板包括：多条扫描线Gn-Gn+5、多条数据线Dm-Dm+4以及多个像素。所述像素包括红色像素101、绿色像素102以及蓝色像素103。相邻两个像素的颜色不同，具体地位于同一行或者同一列中相邻两个像素的颜色不同。也即RGB像素交错分布。第一列像素依次为RGBRGB，第二列像素依次为BRGBRG，第三列像素依次为GBRGBR。
所述多个像素形成像素矩阵。每行像素对应设置一条扫描线，也即扫描线的数量等于像素行的数量。第n列像素对应第n条数据线和第n+1条数据线，第n条数据线和第n+1条数据线交替连接第n列像素中的每个像素，N≥2，0＜n＜N。也即第n条数据线和第n+1条数据线交替连接第n列像素中的位于不同行的像素。第一列像素对应连接第1条数据线Dm和第2条数据线Dm+2。第1条数据线Dm和第2条数据线Dm+2交替连接第一列的像素。
在一实施方式中，所述第n+1条数据线与所述第n+1列像素的偶数行像素连接，且与第n列像素的奇数行像素连接。例如，如图5所示，第2条数据线Dm+2与第一列像素的奇数行像素连接，并且与第2列像素的偶数行像素连接。
进一步地，所述第n+1条数据线连续驱动两个同种颜色的像素。其中，所述第n+1条数据线连续驱动分别位于第n列和第n+1列的两个同种颜色的像素。
对于每一条数据线而言，第n+1条数据线依次驱动位于第n列的第一颜色的像素和位于第n+1列的第一颜色的像素、位于第n列的第二颜色的像素和位于第n+1列的第二颜色的像素以及位于第n列的第三颜色的像素和位于第n+1列的第三颜色的像素。该第一颜色比如为红色、第二颜色比如为蓝色、第三颜色为绿色。
比如第2条数据线Dm+2连续驱动位于第一列的红色像素和位于第二列的红色像素，之后连续驱动位于第一列的蓝色像素和位于第二列的蓝色像素，再连续驱动位于第一列的绿色像素和位于第二列的绿色像素。
也即，每条数据线交替连接左右两列像素。以每列像素包括两个像素单元为例，每个像素单元包括3个像素，也即红、绿、蓝像素。以第二条数据线Dm+2为例，先驱动两个红色像素R11、R22，再驱动两个蓝色像素B31、B42，再驱动两个绿色像素G51、G62，其中11、22、31、42、51、62表示像素在矩阵中的位置，前一个编号表示像素所在的行，后一个编号表示像素所在的列，比如11表示第1行第1列的像素。
其中所述位于第n列和第n+1列的两个同种颜色的像素位于相邻两行。所述两个第一颜色的像素位于相邻两行，所述两个第二颜色的像素位于相邻两行，两个第三颜色的像素位于相邻两行。比如其中位于第一列的红色像素R11和位于第二列的红色像素R22分别位于第一行和第二行。两个蓝色像素B31、B42位于第三行和第四行，两个绿色像素G51、G62位于第五行和第六行。
如图6所示，给出图5中的驱动信号的波形图。Gn-Gn+5表示第1至6条扫描线上信号的波形图、Dm-Dm+4表示第1至5条数据线上的信号的波形图。每条数据线上的信号正负交替。
图7是图5所示结构的显示面板显示纯红色画面的示意图，此时绿色和蓝色像素显示全黑状态，由图可以看出，每条数据线对应的第二个红色像素201-203由重载驱动变为轻载驱动，结合图8，Gn-Gn+5表示第1至6条扫描线上的信号的波形图、Dm+1-Dm+3表示第2至4条数据线上的信号的波形图。由于每条数据线对应的第一个红色像素的数据电压为高电平，第二个红色像素的数据电压也为高电平，因此第二个红色像素的数据电压的电平与上一个像素的数据电压的电平相同，因此该像素为轻载驱动，也即数据线的电压在第二个像素上的数据电压没有高低变化，所谓轻载驱动为数据电压没有高低变化，从而提升了第二个像素的充电能力，进而提升液晶显示器的显示品质。
图9是是纯绿色画面的驱动波形，以第3条数据线Dm+2上具有12个像素为例，t11-t13分别表示第三条数据线中第一个、第二个蓝色像素的数据电压，t13-t15表示该列中第一个、第二个绿色像素的数据电压，t15-t17表示该列中第一个、第二个红色像素的数据电压，t17-t19分别表示第三条数据线中第三个、第四个蓝色像素的数据电压，t19-t21表示该列中第三个、第四个绿色像素的数据电压，t21-t23表示该列中第三个、第四个红色像素的数据电压。
图9仅给出一列像素的驱动波形，其中21表示外部提供的数据电压（也即初始数据电压），22表示实际的数据电压，由于数据线上的第二个绿色像素的电压未处于高低变化状态，所以第二个绿色像素为轻载驱动，也即相对于图4由重载驱动变为轻载驱动，从而提升了第二个像素的充电能力，进而提升液晶显示器的显示质量。可以理解的，蓝色像素的驱动信号的波形与此类似，在此不再赘述。
可以理解的，在另一实施方式中，所述第n+1条数据线也可与所述第n+1列像素的奇数行像素连接，且与第n列像素的偶数行像素连接。
本发明实施例还提供一种液晶显示装置，其包括背光模块及液晶显示面板。如图5所示，该液晶显示面板包括：多条扫描线Gn-Gn+5、多条数据线Dm-Dm+4以及多个像素。所述像素包括红色像素101、绿色像素102以及蓝色像素103。相邻两个像素的颜色不同，具体地位于同一行或者同一列中相邻两个像素的颜色不同。也即RGB像素交错分布。第一列像素依次为RGBRGB，第二列像素依次为BRGBRG，第三列像素依次为GBRGBR。
所述多个像素形成像素矩阵。每行像素对应设置一条扫描线，也即扫描线的数量等于像素行的数量。第n列像素对应第n条数据线和第n+1条数据线，第n条数据线和第n+1条数据线交替连接第n列像素中的每个像素，N≥2，0＜n＜N。也即第n条数据线和第n+1条数据线交替连接第n列像素中的位于不同行的像素。第一列像素对应连接第1条数据线Dm和第2条数据线Dm+2。第1条数据线Dm和第2条数据线Dm+2交替连接第一列的像素。
在一实施方式中，所述第n+1条数据线与所述第n+1列像素的偶数行像素连接，且与第n列像素的奇数行像素连接。例如，如图5所示，第2条数据线Dm+2与第一列像素的奇数行像素连接，并且与第2列像素的偶数行像素连接。
进一步地，所述第n+1条数据线连续驱动两个同种颜色的像素。其中，所述第n+1条数据线连续驱动分别位于第n列和第n+1列的两个同种颜色的像素。
对于每一条数据线而言，第n+1条数据线依次驱动位于第n列的第一颜色的像素和位于第n+1列的第一颜色的像素、位于第n列的第二颜色的像素和位于第n+1列的第二颜色的像素以及位于第n列的第三颜色的像素和位于第n+1列的第三颜色的像素。该第一颜色比如为红色、第二颜色比如为蓝色、第三颜色为绿色。
比如第2条数据线Dm+2连续驱动位于第一列的红色像素和位于第二列的红色像素，之后连续驱动位于第一列的蓝色像素和位于第二列的蓝色像素，再连续驱动位于第一列的绿色像素和位于第二列的绿色像素。
也即，每条数据线交替连接左右两列像素。以每列像素包括两个像素单元为例，每个像素单元包括3个像素，也即红、绿、蓝像素。以第二条数据线Dm+2为例，先驱动两个红色像素R11、R22，再驱动两个蓝色像素B31、B42，再驱动两个绿色像素G51、G62，其中11、22、31、42、51、62表示像素在矩阵中的位置，前一个编号表示像素所在的行，后一个编号表示像素所在的列，比如11表示第1行第1列的像素。
其中所述位于第n列和第n+1列的两个同种颜色的像素位于相邻两行。所述两个第一颜色的像素位于相邻两行，所述两个第二颜色的像素位于相邻两行，两个第三颜色的像素位于相邻两行。比如其中位于第一列的红色像素R11和位于第二列的红色像素R22分别位于第一行和第二行。两个蓝色像素B31、B42位于第三行和第四行，两个绿色像素G51、G62位于第五行和第六行。
如图6所示，给出图5中的驱动信号的波形图。Gn-Gn+5表示第1至6条扫描线上信号的波形图、Dm-Dm+4表示第1至5条数据线上的信号的波形图。每条数据线上的信号正负交替。
图7是图5所示结构的显示面板显示纯红色画面的示意图，此时绿色和蓝色像素显示全黑状态，由图可以看出，每条数据线对应的第二个红色像素201-203由重载驱动变为轻载驱动，结合图8，Gn-Gn+5表示第1至6条扫描线上的信号的波形图、Dm+1-Dm+3表示第2至4条数据线上的信号的波形图。由于每条数据线对应的第一个红色像素的数据电压为高电平，第二个红色像素的数据电压也为高电平，因此第二个红色像素的数据电压的电平与上一个像素的数据电压的电平相同，因此该像素为轻载驱动，也即数据线的电压在第二个像素上没有高低变化，从而提升了第二个像素的充电能力，进而提升液晶显示器的显示品质。
图9是是纯绿色画面的驱动波形，以第3条数据线Dm+2上具有12个像素为例，t11-t13分别表示第三条数据线中第一个、第二个蓝色像素的数据电压，t13-t15表示该列中第一个、第二个绿色像素的数据电压，t15-t17表示该列中第一个、第二个红色像素的数据电压，t17-t19分别表示第三条数据线中第三个、第四个蓝色像素的数据电压，t19-t21表示该列中第三个、第四个绿色像素的数据电压，t21-t23表示该列中第三个、第四个红色像素的数据电压。

可以理解的，在另一实施方式中，所述第n+1条数据线也可与所述第n+1列像素的奇数行像素连接，且与第n列像素的偶数行像素连接。
本发明的液晶显示面板及装置，由于每条数据线交替驱动两列像素，使得在显示单色画面时，可以连续驱动两个同种颜色的像素，使得第二个像素由重载驱动变为轻载驱动，提升第二个像素的充电能力，并降低了源驱动芯片的功耗，提高了液晶显示面板的显示质量。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
