， 且同一列子像素中任意相邻的两个子像素的颜色不同。
[0030] 在具体应用中， 像素阵列 10所包括的子像素的行数和列数由三栅极晶体管的大 小和对显示面板的尺寸要求来决定。
[0031] 图 1中示例性的示出像素阵列 10包括 9列子像素和 9行子像素， 即像素阵列 10的 总子像素个数为 9x9; 对应的， 源极驱动芯片 20引出分别与 9列子像素连接的 9根 扫描线， 分别表示为 Sl、 S2、 ......、 S8和 S9， 源极驱动芯片 20的 9根数据线依次 输出数据信号对每列子像素进行数据驱动控制； 栅极驱动芯片 30引出分别与 9行 子像素连接的 9根扫描线， 分别表示为 Gl、 G2、 ......、 G8和 G9， 栅极驱动芯片 3
0的 9根扫描线依次输出扫描信号给每行子像素充电。
[0032] 在具体应用中， 像素阵列 10中同一列子像素中各子像素的颜色可以根据实际需 要设定。
[0033] 在一个实施例中， 像素阵列 10中同一列子像素按照第一颜色子像素、 第二颜色 子像素和第三颜色子像素的排列顺序周期性排列。
[0034] 图 1中示例性的示出， 第一颜色为红色 （即 Red, 图 1中用 R表示） 、 第二颜色 为绿色 （即 Green, 图 1中用 G表示） 、 第三颜色为蓝色 （即 Blue, 图 1中用 B表示
[0035] 如图 2所示， 采用常用的点反转驱动方式驱动图 1中的像素阵列吋， 相邻子像素 的极性均不相同。 图 1中示例性的示出位于 S1列、 G1行的红色子像素的驱动极性 为正 （图 2中用符号表示为 +) ， 位于 S1列、 G2行的绿色子像素的驱动极性为负 (图 2中用符号表示为-) ， 位于 S1列、 G3行的蓝色子像素的驱动极性为正， 其 他各像素的驱动极性按照上述 "相子邻像素的极性均不相同"的规律类推， 此处不 再一一列举。 在具体应用中， 位于 S1列、 G1行的红色子像素的驱动极性也可以 为负， 对应的， 其他各子像素的驱动极性按照上述规律类推， 此处不再一一列 举。
[0036] 如图 3所示， 按照图 2所示的驱动极性驱动像素阵列吋， 栅极驱动芯片 30的 9根 扫描线 G1~G9依次输出高电平对位于 S1列的子像素依次充电， 源极驱动芯片 20 的数据线 S1每驱动一个位于 S1列上的一个子像素其输出的驱动电压信号反转一 次， 其工作频率即为其输出的驱动电压信号的反转频率。 源极驱动芯片 20的其 他数据线 S2~S8工作吋输出的驱动电压信号的反转频率与数据线 S 1相同， 图 3中 仅示例性的示出了驱动 S1列像素吋的驱动电压信号的示意图， 图 3中凸起的波形 表示高电平信号、 下凹的波形表示低电平信号。
[0037] 如图 4所示， 本申请的一个实施例提供一种显示面板的驱动方法， 用于对图 1所 示的像素阵列进行驱动， 该驱动方法包括： [0038] 步骤 S101 : 对显示面板的像素阵列进行分组， 每组像素包括 MxN个子像素且每 组像素的第一行或第 M行子像素为蓝色子像素； 其中， M， N≥l且为正整数； [0039] 步骤 S102: 在对所述像素阵列进行驱动的过程中， 控制与所述像素阵列连接的 源极驱动芯片输出的驱动电压信号的极性周期性反转， 使所述每组像素中的所 有子像素的极性相同且任意相邻的两组像素的极性相反。
[0040] 在一个实施例中， 每组像素中第一行子像素为第一颜色子像素、 第二行子像素 为第二颜色子像素、 第三行子像素为第三颜色子像素； 其中， 第一颜色为蓝色
[0041] 在一个实施例中， 每组像素中第一行子像素为第一颜色子像素、 第二行子像素 为第二颜色子像素、 第三行子像素为第三颜色子像素； 其中， 第三颜色为蓝色
[0042] 在具体应用中， 第一颜色、 第二颜色或第三颜色可以分别为红色、 绿色和蓝色 中的任意一种颜色， 三种颜色可以各不相同或部分不同。 只要保证每组像素中 第一行或最后一行的子像素颜色为蓝色即可。
[0043] 在具体应用中， 可以根据实际需要设定 M和 N的数值， M的数值大小与源极驱 动芯片的工作频率线性负相关， 即 M越大， 源极驱动芯片的工作频率越低， 其发 热量越低； 同理， N的数值大小与栅极驱动芯片的工作频率线性负相关， 即 N越 大， 源极驱动芯片的工作频率越低， 其发热量越低。
[0044] 在一个实施例中， M=3且 N=l。
[0045] 如图 5所示， 示例性的示出了 M=3且 N=l吋， 通过上述驱动方法驱动图 1中的像 素阵列吋的驱动极性示意图。 图 5中， 同一列像素中每组三个子像素的驱动极性 均相同且任意相邻的两组像素的极性相反。 图 5中所示出的子像素的驱动极性均 是示例性的， 在实际应用中， 将图 5中每个子像素的驱动极性均设置为与图 5所 示的极性完全相反的极性， 也同样在上述驱动方法的保护范围之内。
[0046] 如图 6所示， 按照图 5所示的驱动极性驱动像素阵列吋， 栅极驱动芯片 30的 9根 扫描线 G1~G9依次输出高电平信号对位于 S1列的子像素依次充电， 源极驱动芯 片 20的数据线 S1每驱动 S1列上的一组像素所包括的三个子像素反转一次驱动电 压信号的极性， 其工作频率即为其驱动电压信号的极性反转频率。 源极驱动芯 片 20的其他数据线 S2~S8工作吋的驱动电压信号的极性反转频率与数据线 SI相同
。 图 6中仅示例性的示出了驱动 S1列子像素吋的驱动电压信号的示意图， 图 6中 凸起的波形表示高电平信号、 下凹的波形表示低电平信号。
[0047] 比较图 3和图 6可知， 按照图 5所示的驱动极性驱动像素阵列， 可以将源极驱动 芯片 20的工作频率降低为按照图 2所示的驱动极性驱动像素阵列吋的 1/3。 因此， 按照图 5所示的驱动极性来驱动像素阵列可以有效降低源极驱动芯片的工作频率
， 从而减少源极驱动芯片的发热量， 提高其使用寿命。
[0048] 图 5中每次发生驱动电压信号的极性反转的位置都位于蓝色子像素位置， 由于 人眼对蓝色不敏感， 因此， 在蓝色子像素位置处反转驱动电压信号的极性可以 减轻对显示面板显示效果的影响。
[0049] 如图 7所示， 示例性的示出了 M=N=3吋， 通过上述驱动方法驱动图 1中的像素阵 列吋的驱动极性示意图。 图 7中， 每组九个子像素的驱动极性均相同且任意相邻 的两组像素的极性相反。 图 7中所示出的子像素的驱动极性均是示例性的， 在实 际应用中， 将图 7中每个子像素的驱动极性均设置为与图 7所示的极性完全相反 的极性， 也同样在上述驱动方法的保护范围之内。
[0050] 如图 8所示， 本申请实施例提供一种显示面板的驱动装置 100， 其中， 显示面板
200包括像素阵列 201和源极驱动芯片 202， 驱动装置包括控制模块 101。
[0051] 像素阵列 201包括多组像素， 每组像素包括 MxN个子像素且每组像素的第一行 或第 M行子像素为蓝色子像素； 其中， M， N≥l且为正整数。

[0055] 控制模块 101， 用于在对像素阵列 201进行驱动的过程中， 控制源极驱动芯片 20
2输出的驱动电压信号的极性周期性反转， 使每组像素中的所有子像素的极性相 同且任意相邻的两组像素的极性相反。
[0056] 在一个实施例中， 控制模块具体可以为吋序控制器， 或者可以是中央处理单元
(Central Processing Unit, CPU) , 还可以是其他通用处理器、 数字信号处理器 (Digital Signal Processor, DSP)、 专用集成电路 (Application Specific Integrated Circuit, ASIC)、 现成可编程门阵列（Field-Programmable Gate Array， FPGA)或 者其他可编程逻辑器件、 分立门或者晶体管逻辑器件、 分立硬件组件等。 通用 处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
[0057] 如图 9所示， 本申请的一个实施例还提供一种显示装置 1000， 包括上述的驱动 装置 100和与驱动装置 100连接的显示面板 200。
