Description

一种液晶显示面板及装置 技术领域
本发明涉及显示技术领域，特别是涉及一种液晶显示面板及装置。
 背景技术
随着液晶显示装置的不断发展，如何使其具有较好的显示效果，成为液晶显示面板目前主要的研究方向之一。
如图1所示，图1为一种现有的液晶显示面板的结构示意图。该液晶显示面板10包括数据线11、扫描线12、以及由数据线11和扫描线12限定形成多个像素行和像素列，其中多条数据线11用于向多个像素列输入数据信号，多条扫描线12用于向多个像素行输入扫描信号，所有的像素可根据相应的数据信号以及相应的扫描信号进行画面显示。该液晶显示面板的一条扫描线12给一行的像素输入扫描信号，一条数据线11给一列的同种颜色的像素输入数据信号，为了防止液晶分子极化现象的发生，每个像素经过一帧画面或几帧画面后，都会进行极性转换，譬如正极性的红色像素转换为负极性的红色像素。
如图1所示，在某一帧画面中，每一列的像素的颜色相同且极性相同，譬如第一列的像素为正极性的红色像素，且同一行中相邻两个像素的极性相反。譬如第一行中正极性的红色像素R+以及负极性的绿色像素G-，正极性的蓝色像素B+与负极性的红色像素R-，正极性绿色像素G+与负极性的蓝色像素B-。
但是上述结构的液晶显示面板的像素在列方向极性交替时，容易造成公共电压发生耦合，容易产生画面闪烁以及水平串扰等问题。
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
本发明的一个目的在于提供一种液晶显示面板及装置，以解决现有的液晶显示面板及装置，在进行三维显示时容易出现闪烁和水平串扰的技术问题。
 技术解决方案

多条数据线，用于传输数据信号；
多条扫描线，用于传输扫描信号；以及
多个像素单元，包括多个像素，所述像素的颜色包括红色、绿色、蓝色；由多条所述数据线限定的全部所述像素形成多个像素列；或者由多条所述扫描线限定的全部所述像素形成多个像素行；
其中，每一列中的所有所述像素的颜色相同，相邻两个所述像素单元中同种颜色的像素的极性相反；每个所述像素单元中相邻两个像素的极性相反，每条所述数据线连接相同极性的所述像素；
当所述液晶显示面板进行二维显示时，所述扫描线进行逐行扫描；

附图说明
图1是现有的液晶显示面板的结构示意图；
图2是本发明的液晶显示面板的结构示意图。
 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2，图2为本发明的液晶显示面板的结构示意图。
本发明的液晶显示面板20，包括阵列基板，所述阵列基板包括多条数据线21、多条扫描线22以及多个像素单元，所述像素单元包括多个像素，所述像素的颜色包括红色、绿色、蓝色；当然也可以包括黄色或白色，本发明仅以所述像素单元中的像素排列顺序为红色、绿色、蓝色（RGB）的方式举例说明，不构成对本发明的限定。
由多条所述数据线限定的全部所述像素形成多个像素列；或者由多条所述扫描线限定的全部所述像素形成多个像素行；其中所述数据线可向多个像素列输入数据信号，所述扫描线可向多个像素行输入扫描信号，所述像素单元可根据相应的数据信号以及相应的扫描信号进行画面显示。
如图2所示，每一列中的所有所述像素的颜色相同，相邻两个所述像素单元中同种颜色的像素的极性相反；也即同一列中相邻两个所述像素的极性相反；同一行中相邻两个所述像素的极性也相反；譬如像素单元101中红色像素的极性为正R+，像素单元102中红色像素的极性为负R-，像素单元101中绿色像素的极性为正G+，像素单元102中绿色像素的极性为负G-；像素单元101中蓝色像素的极性为正B+，像素单元102中蓝色像素的极性为负B-；像素单元101中红色像素的极性为正R+，像素单元103中红色像素的极性也为负R-；每个所述像素单元中相邻两个像素的极性相反，譬如像素单元101中红色像素的极性为正R+，绿色像素的极性为负G-，蓝色像素的极性为正B+。每条所述数据线连接相同极性的所述像素，譬如从左至右第一条数据线连接负极性的红色像素R-；第二条数据线连接正极性的红色像素R+和正极性的绿色像素G+。
优选地，所述液晶显示面板20进行二维显示时，由于对画面显示的刷新频率较低，可对液晶显示面板20的所有扫描线22进行逐行扫描，以确保二维显示的画面显示质量。
优选地，所述液晶显示面板20进行三维显示时，由于需要配合3D快门眼镜同时显示左眼画面以及右眼画面，即二维显示时的一帧画面的显示时间在三维显示时需要显示两帧画面，因此画面显示的刷新频率较高，液晶显示面板20的刷新频率可为120Hz至240Hz。这时为了保证数据线21可以使用数据信号对像素单元进行充分的充电，全部的所述扫描线22可以按照扫描线组的顺序依次进行扫描，其中所述扫描线组为位于2k行（偶数行）中的多个相邻的所述扫描线或者位于2k+1行（奇数行）中的多个相邻的所述扫描线，其中k为正整数，譬如所述扫描线组可为位于2k行（偶数行）中的2-4个相邻的扫描线或位于2k+1（奇数行）行中的2-4个相邻的扫描线。
譬如第一行像素和第三行像素相同；且这两行像素的极性也相同，即可以输入相同的数据信号，因此对这两行的扫描线进行扫描，可以减少充电时间，使得所述像素单元进行充分地充电。
由于每条数据上连接有正极性的像素也有负极性的像素，且正极性的像素的数目和负极性的像素的数目相等，这种结构可使得数据线之间对公共电压的耦合作用相互抵消，从而有效地防止公共电压的偏移，可以避免水平串扰和闪烁等问题，因此在本发明的液晶显示面板比现有的液晶显示面板，具有更好的显示效果。
所述液晶显示面板还可包括彩膜基板，所述彩膜基板可包括黑色矩阵和公共电极。
所述像素还可包括薄膜晶体管，所述扫描线连接所述像素的薄膜晶体管的控制端；所述数据线连接所述像素的薄膜晶体管的输入端。
所述液晶显示面板还可包括栅驱动芯片和源驱动芯片，所述栅驱动芯片连接所述扫描线，并通过所述扫描线向每行所述像素输入扫描信号；所述源驱动芯片连接所述数据线，并通过所述数据线向每列所述像素输入数据信号。
本发明还包括一种液晶显示装置，其包括：背光模块及液晶显示面板，本发明的液晶显示面板包括阵列基板，所述阵列基板包括多条数据线21、多条扫描线22以及多个像素单元，所述像素单元包括多个像素，所述像素的颜色包括红色、绿色、蓝色；当然也可以包括黄色或白色，本发明仅以所述像素单元中的像素排列顺序为红色、绿色、蓝色（RGB）的方式举例说明，不构成对本发明的限定。
由多条所述数据线限定的全部所述像素形成多个像素列；或者由多条所述扫描线限定的全部所述像素形成多个像素行；其中所述数据线可向多个像素列输入数据信号，所述扫描线可向多个像素行输入扫描信号，所述像素单元可根据相应的数据信号以及相应的扫描信号进行画面显示。
如图2所示，每一列中的所有所述像素的颜色相同，相邻两个所述像素单元中同种颜色的像素的极性相反；也即同一列中相邻两个所述像素的极性相反；同一行中相邻两个所述像素的极性也相反；譬如像素单元101中红色像素的极性为正R+，像素单元102中红色像素的极性为负R-，像素单元101中绿色像素的极性为正G+，像素单元102中绿色像素的极性为负G-；像素单元101中蓝色像素的极性为正B+，像素单元102中蓝色像素的极性为负B-；像素单元101中红色像素的极性为正R+，像素单元103中红色像素的极性也为负R-；每个所述像素单元中相邻两个像素的极性相反，譬如像素单元101中红色像素的极性为正R+，绿色像素的极性为负G-，蓝色像素的极性为正B+。每条所述数据线连接相同极性的所述像素，譬如从左至右第一条数据线连接负极性的红色像素R-；第二条数据线连接正极性的红色像素R+和正极性的绿色像素G+。
优选地，所述液晶显示面板20进行二维显示时，由于对画面显示的刷新频率较低，可对液晶显示面板20的所有扫描线22进行逐行扫描，以确保二维显示的画面显示质量。
优选地，所述液晶显示面板20进行三维显示时，由于需要配合3D快门眼镜同时显示左眼画面以及右眼画面，即二维显示时的一帧画面的显示时间在三维显示时需要显示两帧画面，因此画面显示的刷新频率较高，液晶显示面板20的刷新频率可为120Hz至240Hz。这时为了保证数据线21可以使用数据信号对像素单元进行充分的充电，全部的所述扫描线22可以按照扫描线组的顺序依次进行扫描，其中所述扫描线组为位于2k行（偶数行）中的多个相邻的所述扫描线或者位于2k+1行（奇数行）中的多个相邻的所述扫描线，其中k为正整数，譬如所述扫描线组可为位于2k行中的2-4个相邻的扫描线或位于2k+1行中的2-4个相邻的扫描线。
即譬如第一行像素和第三行像素相同；且这两行像素的极性也相同，即可以输入相同的数据信号，因此对这两行的扫描线进行扫描，可以减少充电时间，使得所述像素单元进行充分地充电。
由于每条数据上连接有正极性的像素也有负极性的像素，且正极性的像素的数目和负极性的像素的数目相等，这种结构可使得数据线之间对公共电压的耦合作用相互抵消，从而有效地防止公共电压的偏移，可以避免水平串扰和闪烁等问题，因此在本发明的液晶显示面板比现有的液晶显示面板，具有更好的显示效果。
