本申请涉及显示技术领域，特别涉及一种显示面板驱动方法及其驱动装置、显示装置。
背景技术
目前的显示装置通常通过定向的光阀控制，容易造成大视角色偏，即在一个比较倾斜的角度观看显示屏时，会有颜色偏差的现象出现，使得画面感观具有失真感。而目前为改善这种现象，通常采用以下方法：一种方法是将原本显示装置的像素阵列分为主像素和次像素，并将次像素的亮度调暗，但这种设计容易造成显示面板的穿透率下降；另一种方法是在显示面板的时序处理芯片内部采用数学的特殊算法，对相邻阵列做亮暗数据的设计，但这种设计时序处理芯片内部的算法复杂，调试及维护不易，成本较高。

在一实施例中， 参照图1及图4，本申请实施例提供了一种显示面板100的驱动方法，所述显示面板100包括若干行像素单元L1、L2、L3……Ln，每一行像素单元L由若干个像素S1、S2、S3……Sn构成，该驱动方法包括以下步骤：
步骤S100：接收显示驱动信号；
步骤S200：将所述显示驱动信号分别加载在第一电阻串和第二电阻串上，并分别输出第一电阻串、第二电阻串对应的电阻上的分压电压。
步骤S300：按照时序周期逐行驱动各行所述像素单元，且所述第一电阻串输出的分压电压和第二电阻串输出的分压电压分别交替驱动相邻两行所述像素单元的奇数位置像素和偶数位置像素。
在本实施例中，该显示面板100通常为电视机或计算机等具有显示功能的电子设备的显示面板100，该驱动方法是基于液晶显示面板100的驱动装置200形成的，该驱动装置200包括驱动芯片210和时序控制芯片220。以电视机为例，在步骤S100中，该显示驱动信号通常是由电视机的主板接收到的由天线或机顶盒传输输入的图像信号经编码后形成的数字信号，驱动芯片210接收到该编码后的数字显示驱动信号后，首先会进行解码运算形成模拟信号，该模拟信号通常为对应的电压信号。
在驱动芯片210内部设置有第一电阻串和第二电阻串，在步骤S200中，驱动芯片210将接收到的数字显示驱动信号转化为相应的模拟电压信号后，分别加载在第一电阻串和第二电阻串上进行伽玛校正。该第一电阻串和第二电阻串均分别由电阻阻值相同的电阻串联连接而成，且该第一电阻串上的各电阻的电阻值和第二电阻值上的各电阻的电阻值不相等。则该模拟电压信号在第一电阻串的各电阻上形成各分压电压与该模拟电压信号在第二电阻串的各电阻上形成的各分压电压也均不相同。驱动芯片210选择第一电阻串和第二电阻串上对应的电阻的分压电压输出。
在本实施例中，以第一电阻串和第二电阻串均包括14个串联的电阻为例进行说明，该第一电阻串具有14个电阻，分别为R1、R2、R3……R14，相应地，第二电阻串也具有14个电阻，分别为R1'、R2'、R3'……R14'。且第一电阻串上的各电阻的电阻值相同，即R1=R2=R3=……R14；第二电阻串上的各电阻的电阻值相同，即R1'=R2'=R3'=……R14'。则模拟电压信号加载在第一电阻串形成15个电位信号，分别为V1、V2、V3……V15，则第一电阻串的各电阻上的分压电压为任意两个相邻的电位值之间的差值，由于第一电阻串上的各电阻值相同，则第一电阻串上的各电阻的分压电压也均相同。相应地，上述模拟电压信号加载在第二电阻串上也形成15个电位信号，分别为V1'、V2'、V3'……V15'，则第二电阻串的各电阻上的分压电压为任意两个相邻的电位值之间的差值，由于第二电阻串上的各电阻值相同，则第二电阻串上的各电阻的分压电压也均相同。则该驱动芯片210可选择第一电阻串上和第二电阻串上任意一个电阻的分压电压输出。由于第一电阻串上各电阻的电阻值与第二电阻串上各电阻的电阻值不相等，即R1≠R1'、R2≠R2'、R3≠R3'……R14≠R14'，则第一电阻串上各电阻的分压电压与第二电阻串上各电阻的分压电压也不相等。
在步骤S300中，该驱动芯片210受时序控制芯片220的控制，以逐行方式驱动显示面板100的各行像素单元，并且根据时序控制芯片220的时序周期交替驱动相邻行像素单元的奇数位置像素和偶数位置像素。
该时序控制芯片220的输出的时序控制信号包括若干个下降沿，相邻两下降沿为一时序周期。
具体地，如图2所示，该步骤S300包括步骤S310和步骤S320：
步骤S310：在前一时序周期内，第一电阻串输出的分压电压驱动前一行像素单元的奇数位置像素，第二电阻串输出的分压电压驱动前一行像素单元的偶数位置像素；
步骤S320：在后一时序周期内，第一电阻串输出的分压电压驱动后一行像素单元的偶数位置像素，第二电阻串输出的分压电压驱动后一行像素单元的奇数位置像素。
在本实施例中，以第一行像素单元L1和第二行像素单元L2为例进行说明，在时序控制芯片220的第一时序周期内，驱动芯片210先驱动第一行像素单元L1，且驱动芯片210输出的第一电阻串的分压电压用于驱动该第一行像素单元L1的奇数位置像素S1、S3、S5……S(2n-1)，驱动芯片210输出的第二电阻串的分压电压用于驱动该第一行像素单元L1的偶数位置像素S2、S4、S6……S(2n)，由于第一电阻串和第二电阻串的输出分压电压不相同，则第一行像素单元L1的奇数位置像素和偶数位置像素所显示的亮度也不同，若第一电阻串输出的分压电压大于第二电阻串的分压电压，则第一行像素单元L1的奇数位置像素的显示亮度将大于第一行像素单元L1的偶数位置像素的显示亮度；相应地，若第一电阻串输出的分压电压小于第二电阻串的分压电压，则第一行像素单元L1的奇数位置像素的显示亮度将小于第一行像素单元L1的偶数位置像素的显示亮度。
第一行像素单元L1驱动完毕后，时序控制芯片220进入第二时序周期，驱动芯片210开始驱动第二行像素单元，且驱动芯片210输出的第一电阻串的分压电压用于驱动该第二行像素单元L2的偶数位置像素S2、S4、S6……S(2n)，驱动芯片210输出的第二电阻串的分压电压用于驱动该第二行像素单元L2的奇数位置像素S1、S3、S5……S(2n-1)，由于第一电阻串和第二电阻串的输出分压电压不相同，则第二行像素单元L2的奇数位置像素和偶数位置像素所显示的亮度也不同，若第一电阻串输出的分压电压大于第二电阻串的分压电压，则第二行像素单元L2的偶数位置像素的显示亮度将大于第二行像素单元L2的奇数位置像素的显示亮度；相应地，若第一电阻串输出的分压电压小于第二电阻串的分压电压，则第二行像素单元L2的偶数位置像素的显示亮度将小于第二行像素单元L2的奇数位置像素的显示亮度。
则根据上述分析，若第一电阻串输出的分压电压大于第二电阻串的分压电压，则第一行像素单元L1的奇数位置像素的亮度将大于偶数位置像素的亮度，而第二行像素单元L2的奇数位置像素的亮度则小于偶数位置像素的亮度。
待全部像素单元逐行驱动完成后，显示面板100的像素单元的亮度显示情况如图5所示，图中阴影部分表示显示亮度较小。则通过上述方法驱动显示面板100后，实现了相邻行对应像素亮暗交错显示的效果，解决了大视角的色偏问题。
在一实施例中，如图3所示，本实施例与上一实施例的区别在于，在步骤S200之后还包括：
步骤S400：将所述第一电阻串、第二电阻串输出的分压电压均进行放大处理。
该放大处理过程为功率放大处理，则根据各像素的所需驱动电压的大小，进行相应放大，达到更好的、更精准驱动的效果。
