Description

显示面板的驱动方法 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板的驱动方法。
 背景技术
随着显示技术的发展，液晶显示装置（Liquid Crystal Display，LCD）等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，已经逐步取代阴极射线管（Cathode Ray Tube，CRT）显示屏，被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩膜（Color Filter，CF）基板之间灌入液晶分子，并在两片基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
在传统的液晶显示装置的驱动架构中，一个像素电极上分别有一条数据线Data line和一条扫描线Gate line，这种做法可以很好地控制每条扫描线上栅极的打开及每条数据线上数据的输入，但是，随着液晶显示面板的解析度的增加和分辨率的增加，数据线及扫描线的条数也会增加，随之带来数据线的扇出走线所占区域的面积增加，从而影响穿透率及显示效果。为解决这一问题，多路复用的驱动架构得到了广泛的应用，例如1to6 De-mux驱动架构，所谓1to6 De-mux驱动架构是指采用分时复用的原理利用一个数据信号为6列像素进行充电的技术。请参阅图1，现有的一种1to6 Dex-mux驱动架构的显示面板包括多个驱动单元。每一驱动单元包括呈多行4列排布的多个像素100、12条数据线200、多条扫描线300及多路复用模块400。每一像素100包括排成一行的三个子像素110，该三个子像素110依次为红色子像素r、绿色子像素g及蓝色子像素b，多个像素100的子像素110排成多行12列，同一列子像素110的颜色相同，一条数据线200对应与一列子像素110，一条扫描线300对应与一行子像素110连接。多路复用模块400包括分别与12列子像素110对应的12个薄膜晶体管T10，12个薄膜晶体管T10的漏极分别连接对应一列子像素110所连接的数据线200，与奇数列子像素110对应的薄膜晶体管T10的源极均接入第N条数据信号DN，N为正整数，与偶数列子像素110对应的薄膜晶体管T10的源极均接入第N+1条数据信号DN+1，第1及第2列像素100中的红色子像素r对应的薄膜晶体管T10的栅极接入第一红色复用信号MUX_R10，第1及第2列像素100中的绿色子像素g对应的薄膜晶体管T10的栅极接入第一绿色复用信号MUX_G10，第1及第2列像素100中的蓝色子像素b对应的薄膜晶体管T10的栅极接入第一蓝色复用信号MUX_B10，第3列及第4列像素100中的红色子像素r对应的薄膜晶体管T10的栅极接入第二红色复用信号MUX_R20，第3列及第4列像素100中的绿色子像素g对应的薄膜晶体管T10的栅极接入第二绿色复用信号MUX_G20，第3列及第4列像素100中的蓝色子像素b对应的薄膜晶体管T10的栅极接入第二蓝色复用信号MUX_B20。
该显示面板进行驱动时包括依次进行的多个帧周期，每一帧周期包括多个依次进行的多个行周期，多条扫描线300依次在多个行周期中为高电平，请参阅图2，在每一个行周期内，第一红色复用信号MUX_R10、第一绿色复用信号MUX_G10、第一蓝色复用信号MUX_B10、第二红色复用信号MUX_R20、第二绿色复用信号MUX_G20、第二蓝色复用信号MUX_B20依次产生一高电平脉冲，以将对应的薄膜晶体管T10打开向对应的子像素110中传输数据信号。此种驱动方式能够减少数据线扇出走线所占空间的面积以实现窄边框，然而，在每一个行周期内，总是第1列及第2列像素100中的红色子像素r、绿色子像素g、蓝色子像素b先被充电，第3列及第4列像素100中的红色子像素r、绿色子像素g、蓝色子像素b后被充电，先被充电的子像素110的显示效果优于后充电的子像素110的显示效果，导致第1列及第2列像素100中的红色子像素r、绿色子像素g、蓝色子像素b的充电效果始终优于第3列及第4列像素100中的红色子像素r、绿色子像素g、蓝色子像素b的充电效果，使得如图3所示，第1列及第2列像素100与第3列及第4列像素100之间产生亮度差异，最终导致显示面板显示的画面出现条纹感，影响显示的效果。

所述第 2i 个复用周期包括 p 个第二行周期，每一第二行周期中，第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 、第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 依次产生一个高电平脉冲。
具体地，请参阅图 6 ，在本发明的第一实施例中，所述第 2i 个复用周期包括 1 个第二行周期。在第 2i 个复用周期中，第 q+1 条扫描线 30 上的电压 Gq+1 为高电位，多条扫描线 30 中除了第 q+1 条扫描线 30 以外的扫描线 30 上的电压均为低电位。也即在本发明的第一实施例中，第 2i 个复用周期与第 q+1 条扫描线 30 对应的第 q+1 行子像素 11 的开启时刻对应。
具体地，第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 、第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 、第 n 条数据信号 Dn 及第 n+1 条数据信号 Dn+1 由外部驱动芯片提供。
需要说明的是，本发明的显示面板的驱动方法的第一实施例中，通过使得第 2i-1 个复用周期也即第 q 条扫描线 30 对应的第 q 行子像素 11 的开启时刻内，第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 、第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 依次产生一个高电平脉冲，从而使得在第 2i-1 个复用周期中，受第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 控制的开关单元 41 所对应的子像素 11 也即第 1 列及第 2 列像素 10 中的子像素 11 的充电时刻早于受第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 控制的开关单元 41 所对应的子像素 11 也即第 3 列及第 4 列像素 10 中的子像素 11 的充电时刻，而在第 2i 个复用周期也即第 q+1 条扫描线 30 对应的第 q+1 行子像素 11 的开启时刻内，第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 、第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 依次产生一个高电平脉冲，从而使得在第 2i 个复用周期内，受第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 控制的开关单元 41 所对应的子像素 11 也即第 1 列及第 2 列像素 10 中的子像素 11 的充电时刻晚于受第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 控制的开关单元 41 所对应的子像素 11 也即第 3 列及第 4 列像素 10 中的子像素 11 的充电时刻，从而请参阅图 7 ，显示时，同一列像素 10 中，充电效果好的像素 10 与充电效果差的像素 10 交替设置且两者相互叠加，从而消除了显示面板显示的画面的条纹感，有效地提升显示品质。
请参阅图 5 并结合图 8 ，本发明的显示面板的驱动方法的第二实施例与上述第一实施例的区别在于：
请参阅图 8 ，所述步骤 S2 中，所述第 2i-1 个复用周期包括 2 个依次进行的第一行周期，所述第 2i 个复用周期包括 2 个依次进行的第二行周期。在所述第 2i-1 个复用周期的两个第一行周期的第一个中，第 q 条扫描线 30 上的电压为高电位，多条扫描线 30 中除了第 q 条扫描线 30 以外的扫描线 30 上的电压均为低电位。 q 为正整数。在所述第 2i-1 个复用周期的两个第一行周期的第二个中，第 q+1 条扫描线 30 上的电压为高电位，多条扫描线 30 中除了第 q+1 条扫描线 30 以外的扫描线 30 上的电压均为低电位。也即在本发明的第二实施例中，第 2i-1 个复用周期中的两个第一行周期分别与第 q 条扫描线 30 对应的第 q 行子像素 11 的开启时刻以及第 q+1 条扫描线 30 对应的第 q+1 行子像素 11 的开启时刻对应。
请参阅图 8 ，所述步骤 S3 中，在所述第 2i 个复用周期的两个第二行周期的第一个中，第 q+2 条扫描线 30 上的电压 Gq+2 为高电位，多条扫描线 30 中除了第 q+2 条扫描线 30 以外的扫描线 30 上的电压均为低电位。在所述第 2i 个复用周期的两个第二行周期的第二个中，第 q+3 条扫描线 30 上的电压 Gq+3 为高电位，多条扫描线 30 中除了第 q+3 条扫描线 30 以外的扫描线 30 上的电压均为低电位。也即在本发明的第二实施例中，第 2i 个复用周期中的两个第二行周期分别与第 q+2 条扫描线 30 对应的第 q+2 行子像素 11 的开启时刻以及第 q+3 条扫描线 30 对应的第 q+3 行子像素 11 的开启时刻对应。
其余均与上述第一实施例相同，在此不再赘述。
需要说明的是，显示面板有时会显示如图 9 所示的亮暗交替的画面，此时，奇数行奇数列及偶数行偶数列的像素 10 发光呈亮态，而奇数行偶数列及偶数行奇数列的像素 10 不发光呈暗态，此时若仍采用上述第一实施例的方式进行驱动，同一列像素 10 中，呈亮态的像素 10 的充电效果一致，不同列像素 10 中呈亮态的像素 10 的充电效果不同，仍旧会产生条纹问题，因此，本发明的显示面板的驱动方法的第二实施例中，通过使得第 2i-1 个复用周期也即第 q 条扫描线 30 对应的第 q 行子像素 11 的开启时刻及第 q+1 条扫描线 30 对应的第 q+1 行子像素 11 的开启时刻内，第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 、第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 依次产生一个高电平脉冲而后再依次产生一个高电平脉冲，从而使得在第 2i-1 个复用周期中，受第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 控制的开关单元 41 所对应的子像素 11 也即第 1 列及第 2 列像素 10 中的子像素 11 的充电时刻早于受第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 控制的开关单元 41 所对应的子像素 11 也即第 3 列及第 4 列像素 10 中的子像素 11 的充电时刻，而在第 2i 个复用周期也即第 q+2 条扫描线 30 对应的第 q+2 行子像素 11 的开启时刻及第 q+2 条扫描线 30 对应的第 q+2 行子像素 11 的开启时刻内，第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 、第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 依次产生一个高电平脉冲，从而使得在第 2i 个复用周期内，受第一红色复用信号 MUX_R1 、第一绿色复用信号 MUX_G1 、第一蓝色复用信号 MUX_B1 控制的开关单元 41 所对应的子像素 11 也即第 1 列及第 2 列像素 10 中的子像素 11 的充电时刻晚于受第二红色复用信号 MUX_R2 、第二绿色复用信号 MUX_G2 、第二蓝色复用信号 MUX_B2 控制的开关单元 41 所对应的子像素 11 也即第 3 列及第 4 列像素 10 中的子像素 11 的充电时刻，从而请参阅图 9 ，显示时，一列像素 10 划分为多个像素组，每个像素组包括两个像素 10 ，该两个像素 10 的充电效果一致，任意相邻的两个像素组中像素 10 的充电效果不同，从而在显示亮暗交替的画面时，同一列像素 10 中充电效果较好的呈亮态的像素 10 与充电效果较差的呈亮态的像素 10 交替设置且相互叠加，从而消除了显示面板显示的画面的条纹感，有效地提升显示品质。
另外，在本发明的其他实施例中， p 也可根据实际情况选择大于 2 的正整数，并不会影响本发明的实现。
综上所述，本发明的显示面板的驱动方法通过对第一红色、第一绿色、第一蓝色、第二红色、第二绿色及第二蓝色复用信号进行设置，使得在第 2i-1 个复用周期中受第一红色、第一绿色及第一蓝色复用信号控制的开关元件对应的子像素的充电时刻早于受第二红色、第二绿色及第二蓝色复用信号控制的开关元件所对应的子像素的充电时刻，而在第 2i 个复用周期中受第一红色、第一绿色及第一蓝色复用信号控制的开关元件对应的子像素的充电时刻晚于受第二红色、第二绿色及第二蓝色复用信号控制的开关元件所对应的子像素的充电时刻，从而消除显示面板显示的画面的条纹感，提升显示品质。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
