Description

显示面板的驱动方法、驱动装置及显示装置 技术领域
本公开涉及一种显示面板的驱动方法、驱动装置及显示装置。
背景技术
随着液晶显示面板的发展，大视角和低成本成为衡量液晶显示面板的重要指标。在降低液晶显示面板成本的各项技术中，三栅极技术由于其较快的数据传输速度得到了广泛的应用。三栅极技术能够将对像素电极的充电时间缩短为原本充电时间的1/3，相应的，提供数据信号的驱动电路的工作频率变为原来的3倍。
而针对液晶显示面板广视角的实现，一般采用伽马校正对液晶显示面板中的像素单元进行处理，经过伽马校正处理后，在像素单元排列的列方向与行方向上，液晶显示面板中的子像素上数据信号的电平的高低与周围相邻的子像素均不同，这样使得在像素单元排列的行方向和列方向上，每个子像素对应的液晶分子的偏转方向与其周围相邻的子像素对应的液晶分子的偏转方向均不相同，液晶显示面板中的沿不同方向排列的液晶分子形成类似漫反射的效果，增加了观看液晶显示面板时的视角，液晶显示面板依此实现广视角。
综合实现低成本的三栅极技术和实现广视角的伽马校正技术，三栅极技术本身就已经增加了驱动电路的工作频，加之经过伽马校正的子像素与其相邻的子像素上的数据信号的电平的高低均不相同，这样就使得驱动电路提供的数据信号的电平跳变频率大大增加，提高了提供数据信号的驱动电路的功耗，严重 时甚至可能烧毁所述驱动电路。

在步骤S110，将显示面板中的每2n行子像素组成一子像素组，将子像素组中的奇数行子像素组成第一子像素组，将子像素组中的偶数行子像素组成第二子像素组，n为大于1的正整数。
图2为本公开实施提供的一种显示面板的子像素的排列顺序示意图，如图2所示，显示面板包括多行多列排列的像素101组成的像素阵列；其中，每个像素101包括至少三种颜色的子像素，每种颜色的子像素包括第一类型子像素和第二类型子像素，第一类型子像素和第二类型子像素沿像素阵列排列的行方向与列方向上间隔设置，且由驱动电路提供给所述第一类型子像素的数据信号和由驱动电路提供给所述第二类型子像素的数据信号电平高低不同。
参见图2，示例性地设置沿像素阵列排列的列方向上，显示面板中每个像素101包括红色子像素R、绿色子像素G和蓝色子像素B，每种颜色的子像素的第一类型子像素和第二类型子像素沿像素阵列排列的行方向上相邻设置，即红色子像素R包括第一类型子像素RH和第二类型子像素RL，绿色子像素G包括第一类型子像素GH和第二类型子像素GL，蓝色子像素B包括第一类型子像素BH和第二类型子像素BL，且第一类型子像素RH和第二类型子像素RL、第一 类型子像素GH和第二类型子像素GL、第一类型子像素BH和第二类型子像素BL分别沿像素阵列排列的行方向上相邻设置。示例性地设置第一类型子像素RH、GH和BH上由驱动电路提供的数据信号的电平为高，第二类型子像素RL、GL和BL上由驱动电路提供的数据信号的电平为低，这里电平的高低可以是相对的，即第一类型子像素上由驱动电路提供的数据信号的电平高于第二类型子像素上由驱动电路提供的数据信号的电平。则沿像素阵列排列的行方向和列方向上，第一类型子像素和第二类型子像素间隔设置。示例性的，如图2所示，沿像素阵列排列的列方向上，RH、GL、BH、RL、GH和BL间隔设置，沿像素阵列排列的行方向上，RH和RL、GH和GL、BH和BL分别相邻设置。
需要说明的是，图2只是示例性地设置每个像素101包括三种颜色的子像素，只要设置每个像素101包括至少三种颜色的子像素即可，对每个像素101中子像素的个数不作限定，且对每个像素101中的子像素的颜色的排列顺序不作限定，这里以每个像素101中的子像素的排列顺序为RGB为例，显示面板中每个像素中子像素的排列顺序可以是RGB、RBG、GBR、GRB、BRG以及BGR中的任意一种。同时，图2只是示例性地设置第一类型子像素RH、GH和BH上由驱动电路提供的数据信号的电平为高，第二类型子像素RL、GL和BL上由驱动电路提供的数据信号的电平为低；也可以设置第一类型子像素RH、GH和BH上由驱动电路提供的数据信号的电平为低，第二类型子像素RL、GL和BL上由驱动电路提供的数据信号的电平为高，本公开实施例对此不作限定。
为了方便描述，以下实施例以每个像素101中的子像素的排列顺序为RGB，第一类型子像素RH、GH和BH上由驱动电路提供的数据信号的电平为高，第二类型子像素RL、GL和BL上由驱动电路提供的数据信号的电平为低，每个子像素组10中的第一个子像素为第一类型子像素RH为例进行描述，如图2所示。
将显示面板中的每2n行子像素组成一子像素组10，将子像素组10中的奇数行子像素组成第一子像素组，将子像素组10中的偶数行子像素组成第二子像素组，n为大于1的正整数。可选的，n可以为大于1的任意正整数，每个子像素组10中可以包括六行子像素，也可以包括十二行子像素，同一行子像素的颜色可以相同，也可以不相同，本公开实施例对n的具体数值，以及同一行子像素的颜色是否相同不作限定。为了方便描述，以下实施例以每个子像素组10中包括六行子像素，且同一行子像素的颜色相同为例进行说明，如图2所示。则对于每个像素组10，第一子像素组包括第1、3、5行的子像素，第二子像素组包括第2、4、6行的子像素。
可选的，驱动一行子像素进行显示时，通过该行子像素对应的扫描线提供扫描信号，并由该行子像素对应的数据线提供数据信号。每行子像素可以对应同一条扫描线，每列子像素可以对应同一条数据线。图3为图2所示显示面板的驱动时序图，G1-G6分别为一个子像素组10中的六行子像素对应的六个扫描信号，图3示例性地示出了该子像素组10中第一列子像素对应的数据信号S1随G1-G6的变化规律，其它列子像素对应的数据信号的的变化频率与第一列子像素对应的数据信号S1相同。每个扫描信号可以为每行子像素提供触发信号，图3示例性地设置扫描信号按照一定的顺序输入维持时间为T1的高电平信号，也可以为低电平信号，这里以作为触发信号的扫描信号为高电平为例进行说明。当子像素组10中某行子像素对应的数据信号为高电平时，该行子像素进行显示，该行子像素对应的数据线向该行中的子像素提供数据信号。
在步骤S120、对于由2n行子像素组成的子像素组，驱动第一子像素组中的子像素进行显示。
在进行显示时，针对图2所示的显示面板的子像素的排列顺序，对于由2n 行子像素组成的子像素组10，先驱动第一子像素组中的子像素进行显示，即驱动奇数行子像素进行显示，n为大于1的正整数，示例性地设置n为3。如图3所示，先驱动奇数行子像素进行显示，即先驱动第1、3和5行的子像素进行显示，示例性的，每列子像素的第1、3和5行的子像素均为第一类型子像素，即奇数行的子像素上由驱动电路提供的数据信号的电平均为高。以子像素中的第一列子像素为例，如图3所示，在对子像素组10中的奇数行子像素进行驱动的第一阶段T21，由于每列子像素的第1、3和5行的子像素均为第一类型子像素，第一类型子像素上由驱动电路的数据线提供的数据信号的电平均为高，则第一列的奇数行子像素对应的数据线上的数据信号S1的电平均为高，且不会跳变。而现有技术中所提供的显示面板的驱动方法，驱动同样3行子像素进行显示，每列子像素对应的数据线上的数据信号的电平会跳变两次，本公开实施例提供的驱动方法降低了数据信号的电平的跳变频率，进而降低了驱动电路的功耗。
在步骤S130、驱动第二子像素组中的子像素进行显示。
在进行显示时，驱动子像素组10中的第二子像素组中的子像素进行显示，即驱动偶数行子像素进行显示。如图3所示，在第二阶段T22驱动子像素组10中的偶数行子像素进行显示，即驱动第2、4和6行的子像素进行显示，示例性的，每列子像素的第2、4和6行的子像素均为第二类型子像素，即偶数行的子像素上由驱动电路提供的数据信号的电平均为低。以子像素中的第一列子像素为例，如图3所示，在对子像素组10中的偶数行子像素进行驱动的第二阶段T22，由于每列子像素的第2、4和6行的子像素均为第二类型子像素，第二类型子像素上由驱动电路的数据线提供的数据信号的电平均为低，则第一列的偶数行子像素对应的数据线上的数据信号S1的电平均为低，且不会跳变。同样的，现有技术中所提供的显示面板的驱动方法，驱动同样3行子像素进行显示，每列子 像素对应的数据线上的数据信号的电平会跳变两次，本公开实施例提供的驱动方法降低了数据信号的电平的跳变频率，进而降低了驱动电路的功耗。
可选的，如图3所示，各扫面信号的持续时间为T1，按照先驱动2n行子像素组成的子像素组10中的奇数行子像素进行显示，再驱动偶数行子像素进行显示的顺序驱动显示面板中的子像素，使得每条数据线上的数据信号的电平的变化周期为T2，T2为T1的2n倍，以n等于3为例，如图3所示，T2为T1的6倍。在实现三栅极技术降低液晶显示面板成本的同时，相对于现有技术降低了提供数据信号的驱动电路的工作频率，进而降低了驱动电路的功耗，降低了烧毁驱动电路的风险。
可选的，针对图3所示的显示面板的驱动时序，即先驱动子像素组10中的第一子像素组，即驱动奇数行子像素进行显示，再驱动子像素组10的第二子像素组，即驱动偶数行子像素进行显示，在驱动第二子像素组，即偶数行子像素显示时可以先驱动偶数行子像素中蓝色子像素B进行显示。图3在驱动偶数行，即第2、4和6行子像素显示时，示例性地先驱动偶数行子像素中蓝色子像素B进行显示，即先驱动子像素组10中的第6行的蓝色子像素B进行显示，这样在数据信号S1的电平由高变为低时，电平的跳变位置位于蓝色子像素B处。由于相对于红色和绿色，人眼对蓝色最不敏感，使数据信号的电平的跳变位置位于蓝色子像素B处，能够最大程度上减轻数据信号的电平的跳变对显示面板的显示效果的影响。
需要说明的是，上述实施例中在进行显示时，对于由2n行子像素组成的子像素组10，先驱动第一子像素组，即驱动奇数行子像素进行显示，再驱动第二子像素组，即驱动偶数行子像素进行显示。也可以先驱动第二子像素组，即驱动偶数行子像素进行显示，再驱动第一子像素组，即驱动奇数行子像素进行显 示，图4为本公开实施例提供的另一种显示面板的驱动方法的流程示意图，方法包括步骤S210至步骤S230。
在步骤S210、将显示面板中的每2n行子像素组成一子像素组，将子像素组中的奇数行子像素组成第一子像素组，将子像素组中的偶数行子像素组成第二子像素组，n为大于1的正整数。
在步骤S220、对于由2n行子像素组成的子像素组，驱动第二子像素组中的子像素进行显示。
在步骤S230、驱动第一子像素组中的子像素进行显示。
对应的图4所示显示面板驱动方法，图2所示显示面板的驱动时序图如图5所示，数据信号S1由第一阶段T21的低电平跳变至第二阶段T22的高电平，且数据线上的数据信号的电平变化周期T2为扫描信号持续时间T1的2n倍，以n等于3为例，如图5所示，T2为T1的6倍，同样降低了数据信号的电平的跳变频率，进而降低了驱动电路的功耗。
可选的，针对图5所示的显示面板的驱动时序，即先驱动子像素组10中的第二子像素组，即驱动偶数行子像素进行显示，再驱动子像素组10的第一子像素组，即驱动奇数行子像素进行显示，在驱动奇数行子像素显示时可以先驱动奇数上子像素中蓝色子像素B进行显示，即先驱动第3行的蓝色子像素B进行显示，同样能够使得数据信号S1的电平的跳变位置位于蓝色子像素B处，减轻数据信号的电平的跳变对显示面板的显示效果的影响。
需要说明的是，针对驱动子像素组10中的奇数行子像素进行显示时，图3和图5只是示例性的按照第3行、第1行和第5行的顺序进行驱动，针对驱动子像素组10中的偶数行子像素进行显示时，图3和图5只是示例性的按照第6行、第2行和第4行的顺序进行驱动，也可以按照其他的驱动顺序对子像素组 10中的奇数行和偶数行子像素进行驱动，本公开实施例对此不作限定。

控制器接收外部输入的同步信号和时钟信号，产生用于控制栅极驱动电路的第一控制信号，并产生用于控制数据驱动电路的第二控制信号。控制器例如是通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程门阵列(FPGA)等。栅极驱动电路响应从控制器接收的第一控制信号，顺序驱动显示面板的多条栅极线。控制器还向数据驱动电路提供初始数据信号。可选地，初始数据信号是数字信号。

本公开实施例通过将显示面板中的2n行子像素组成一子像素组，将子像素 组中的奇数行子像素组成第一子像素组，将子像素组中的偶数行子像素组成第二子像素组，n为大于1的正整数；对于2n行子像素组成的子像素组，先驱动第一子像素组中的子像素进行显示；后驱动第二子像素组中的子像素进行显示；或者先驱动第二子像素组中的子像素进行显示；后驱动第一子像素组中的子像素进行显示；并设置显示面板包括阵列排列的多个像素单元；每个像素单元包括至少三种颜色的子像素，每种颜色的子像素包括第一类型子像素和第二类型子像素；第一类型子像素和第二类型子像素沿像素单元排列的行方向和列方向上间隔设置，设置第一类型子像素和第二类型子像素上由驱动电路提供的数据信号的电平高低不同。即通过先驱动奇数行子像素进行显示，然后再驱动偶数行子像素进行显示；或者先驱动偶数行子像素进行驱动，然后再驱动奇数行像素进行显示，实现了同时驱动至少两行其上数据信号的电平的高低相同的子像素，降低了驱动电路提供的数据信号的电平的跳变频率，在实现三栅极技术降低液晶显示面板成本的同时，降低了提供数据信号的驱动电路的工作频率，进而降低了驱动电路的功耗，降低了烧毁驱动电路的风险。

如图8所示，本公开还提供一种PVA液晶显示面板(Patterned Vertical Alignment Liquid Crystal Display Panel，PVALCD)及其驱动方法。本实施例的PVA液晶显示面板包括：沿着第一方向X延伸的栅极线G1-G3n，沿着第二方向Y延伸的数据线D1-D2m，以及阵列排布的多个像素单元。第一方向X和第二 方向Y大体上垂直。在本实施例中，多个像素单元设置为n行和m列的矩阵。
每个像素单元包括沿着第二方向Y排列的红色子像素，绿色子像素和蓝色子像素。这些子像素设置为3n行。每个红色、绿色、蓝色子像素包括沿着第一方向设置的高灰度区域和低灰度区域。高灰度区域根据第一伽马曲线被驱动，低灰度区域根据第二伽马曲线被驱动。

参照图8，在本实施例中，第一像素单元101的第一红色子像素RH和第二红色子像素RL在第一方向上顺序排布。第一像素单元101的第二绿色子像素GL和第一绿色子像素GH在第一方向上顺序排布。第一像素单元101的第一蓝色子像素BH和第二蓝色子像素BL在第一方向上顺序排布。第二像素单元102的第二红色子像素RL和第一红色子像素RH在第一方向上顺序排布。第二像素 单元102的第一绿色子像素GH和第二绿色子像素GL在第一方向上顺序排布。第二像素单元102的第二蓝色子像素BL和第一蓝色子像素BH在第一方向上顺序排布。这样，高灰度区域的相邻区域均为低灰度区域，低灰度区域的相邻区域均为高灰度区域。
在驱动本实施例的PVD型液晶显示面板时，将阵列排布的多个像素单元划分为多个驱动组，每个驱动组包括多个像素单元行，依次驱动所述多个驱动组。

可选地，在依次驱动第二行子像素、第四行子像素和第六行子像素时，最后驱动第六行子像素。
在另一个实施例中，首先通过栅极线G2、G4和G6依次驱动第二行子像素，第四行子像素和第六行子像素，之后通过栅极线G1、G3和G5依次驱动第一行子像素、第三行子像素和第五行子像素。
在另一个实施例中，将多个像素单元的第一行至第四行作为一组。该多个像素单元的第一行至第四行包括十二行子像素，这十二行子像素对应栅极线G1-G12。首先，通过奇数编号的栅极线G1、G3...G11依次驱动第一行子像素、第三行子像素...第十一行子像素；之后通过偶数编号的栅极线G2、G4...G12依次驱动第二行子像素、第四行子像素...第十二行子像素。
