Description

显示面板的驱动方法、驱动装置及显示装置 技术领域
本申请涉及显示技术领域，特别是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
传统的垂直配向(Vertical Alignment，VA)液晶显示装置，在显示画面时，由于液晶分子维持一定的偏转角，使得在不同视角下光的透过率不同，造成使用者在不同视角观看画面时会感受到画面的颜色有所差异的色偏现象。
为了改善色偏问题，目前一般的做法是将每个像素单元中RGB子像素的像素电极划分为两个独立的像素电极，对两个像素电极分别施加不同的驱动电压来改善色偏的问题。这种方法，由于像素电极数量的增加，需要重新设计更多的金属走线或TFT(Thin Film Transistor，薄膜晶体管)元件来驱动显示面板，而金属走线和TFT元件不透光，因此这种方法会牺牲可透光开口区、影响面板的透过率、提升背光成本。
为了避免增加金属走线或TFT元件，另一种方法是对每相邻的两个像素单元分别施加高、低两种不同的驱动电压信号。具体的，在同一时刻，每相邻的两个子像素被施加不同极性的驱动电压。采用这种方式，会导致同一列子像素的高电压的正负极性不匹配，即同一列中正极性高电压的子像素数量与负极性高电压的子像素的数量不一致。这样，由于寄生电容的影响，当同一列正极性高电压的子像素数量多于负极性高电压的子像素数量时，公共电压V com的等效电压相较于原V com有所提高，导致正极性高电压的子像素实际充电电荷减少、亮度降低，相反地使得负极性高电压子像素实际充电电荷增 加、亮度增加，进而影响显示颜色及画质，产生画质输出异常的问题。

例如，对显示面板中的各子像素分别施加驱动电压，使得同一像素组中，第二位置像素单元及第三位置像素单元的驱动电压极性与第一位置像素单元的驱动电压极性相反；并且使得同一行像素单元中每相邻的两行子像素的驱动电压极性相反；并且使得所述第一像素单元中的子像素和所述第二像素单元中的子像素的驱动电压的电压等级不同，其中，不同的电压等级包括预设的高电压等级和预设的低电压等级。这样，能够使得显示面板的每一列(row)像素中，被施加高电压等级的正极性驱动电压的子像素的数量和被施加高电压等级的负极性驱动电压的子像素的数量相等，使得V com电压免受寄生电容的影响，从而确保图像信号的正确性，避免发生色偏或画质异常的现象。需要说明的是，本申请实施例的行表示column(纵向)，列表示row(横向)。
其中，第一像素单元和第二像素单元在显示面板中相邻设置。如图2所示，显示面板20具有呈矩阵分布的多个像素单元，所述多个像素单元包括若干第一像素单元P1及若干第二像素单元P2，所述第一像素单元与所述第二像素单元相邻设置，或者说第一像素单元与第二像素单元交替排列。例如，如图2所示，与第一像素单元相邻的像素单元均为第二像素单元，与第二像 素单元相邻的像素单元均为第一像素单元。具体的，每一所述像素单元包括多个子像素，例如每个像素单元包括颜色不同的多个子像素，又如每个像素单元分别包括红色子像素R、绿色子像素G及蓝色子像素B这三种子像素。如图2所示，将第j行至第j+5行的6行像素单元划分为两像素组，分别为第n像素组和第n+1像素组，每像素组各包含3行连续排列的像素单元，例如第n像素组包括连续排列的第j行至第j+2行像素单元，第n+1像素组包括连续排列的第j+3行至第j+5行像素单元。其中，(i，j)表示第i列第j行，(i，j+1)表示第i列第j+1行，(i+1，j)表示第i+1列第j行，以此类推。
以第n像素组为例，如图3所示，第n像素组包括第一位置像素单元P j、第二位置像素单元P j+1及第三位置像素单元P j+2。R1、G1和B1分别表示第一像素单元中的红色子像素、绿色子像素及蓝色子像素。R2、G2和B2分别表示第二像素单元中的红色子像素、绿色子像素及蓝色子像素。H表示第一电压等级，L表示第二电压等级，+表示正极性，-表示负极性。(i，j)表示第i列第j行，(i，j+1)表示第i列第j+1行，(i+1，j)表示第i+1列第j行，以此类推。
根据上述驱动方法，对同一像素组中的第二位置像素单元及第三位置像素单元分别施加与第一位置像素单元极性相反的驱动电压。例如，对同一像素组中的第一位置像素单元及第二位置像素单元分别施加极性相反的驱动电压，并且对同一像素组中的第三位置像素单元施加与第二位置像素单元极性相同的驱动电压。又如，在同一像素组中，对第一位置像素单元的第一子像素和第三子像素分别施加第一极性的驱动电压，对第二位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压，并对第三位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压；对第一位置像素单元的第二子像素施加第二极性的驱动电压，对第二位置像素单元的第二子像素施加第一极性的驱动电压，并对第三位置像素单元的第二子像素施加第一极性的驱动电压；其中第一极性与第二极性互为相反极性，例如第一极性为正极性，第二极性为负极性；或者第一极性为负极性，第二极性为正极性。 本实施例中，正极性指的是驱动电压的大小大于显示面板预设的公共电压V com，即驱动电压与V com电压的压差大于零；负极性指的是驱动电压的大小小于V com电压，即驱动电压与V com电压的压差小于零。
如图3所示，以第n像素组为例，对第一位置像素单元P j的R子像素、G子像素和B子像素分别施加正极性、负极性、正极性的驱动电压，对第二位置像素单元P j+1的R子像素、G子像素和B子像素分别施加负极性、正极性、负极性的驱动电压，对第三位置像素单元P j+2的R子像素、G子像素和B子像素分别施加负极性、正极性、负极性的驱动电压，使得第一位置像素单元P j的驱动电压极性与第二位置像素单元P j+1的驱动电压极性相反，第三位置像素单元P j+2的驱动电压极性与第二位置像素单元P j+1的驱动电压极性相同。
根据上述驱动方法，对同一行像素单元中每相邻的两行子像素分别施加极性相反的驱动电压。例如，对同一行像素单元中的所述第一子像素和所述第三子像素施加极性相同的驱动电压，并且对同一行像素单元中的所述第二子像素施加与所述第一子像素极性相反的驱动电压。又如，如图3所示，每一像素单元中R子像素、G子像素和B子像素依次排列，以第j行为例，对G子像素施加负极性的驱动电压，对R子像素和B子像素分别施加正极性的驱动电压，使得同一行中每相邻的两行子像素的驱动电压极性相反。
根据上述驱动方法，对所述第一像素单元中的子像素和所述第二像素单元中的子像素分别施加不同电压等级的驱动电压。例如，分别预先设置第一像素单元和第二像素单元各自对应的驱动电压等级，又如，预先设置第一像素单元对应的第一驱动电压等级及第二像素单元对应的第二驱动电压等级。
作为一种实施方式，对所述第一像素单元中的子像素施加预设第一电压等级的驱动电压；对所述第二像素单元中的子像素施加预设第二电压等级的驱动电压。其中，第一驱动电压等级和第二驱动电压等级中，一个为高电压等级，另一个为低电压等级。例如，第一驱动电压等级高于第二驱动电压等级，或者第一驱动电压等级低于第二驱动电压等级。作为一种实施方式，所 述预设第一电压等级与所述预设第二电压等级分别为一个数组中的两个相异数值；例如，所述数组为预设驱动电压等级数组，其中包含多个相异的驱动电压等级，所述预设第一电压等级与所述预设第二电压等级分别为所述预设驱动电压等级数组中的两个相异的驱动电压等级。作为一种实施方式，所述第一驱动电压等级和所述第二驱动电压等级每经过一预设时间周期互置一次，即，每过一段时间，或者说每经过一个预设时间周期，更新所述第一驱动电压等级和所述第二驱动电压等级，将所述第一驱动电压等级设置为原先的第二驱动电压等级，并将所述第二驱动电压等级设置为原先的第一驱动电压等级，这样，可以在使得像素单元在侧视角下的灰阶亮度曲线接近于正视角下的灰阶亮度曲线的基础上进一步保证长期运行达到均匀显示的效果。进一步地，所述预设时间周期根据相邻两帧显示时间设置或者调整，或者所述预设时间周期根据帧频设置或者调整，也就是说，对于不同的帧频，这个预设时间周期是不同的，这样，可以确保对于不同显示用途的显示面板具有合适的预设时间周期，从而使得在调整所述第一驱动电压等级和所述第二驱动电压等级时能够与显示面板的显示相适配；进一步地，所述预设时间周期与相邻两帧显示时间成正比，或者，所述预设时间周期与显示面板的帧频成反比；例如，相邻两帧显示时间间隔越长，则预设时间周期越长，或者，帧频越大，则预设时间周期越小，以此类推。进一步地，所述驱动方法还包括：预设置所述预设时间周期。进一步地，所述驱动方法还包括：预设置变幅系数范围；并且，所述第一驱动电压等级和所述第二驱动电压等级每经过一预设时间周期互置一次，包括：所述第一驱动电压等级和所述第二驱动电压等级每经过一预设时间周期互置一次且在互置过程中根据所述变幅系数范围随机获取一个变幅系数进行调整；例如，每经过一个预设时间周期，更新所述第一驱动电压等级和所述第二驱动电压等级，将所述第一驱动电压等级设置为原先的第二驱动电压等级乘以从所述变幅系数范围随机获取一个变幅系数的积，并将所述第二驱动电压等级设置为原先的第一驱动电压等级乘以从所述变幅系数范围随机获取一个变幅系数的积；例如，互置过程中，两个变幅 系数相同或相异设置。例如，每经过一个预设时间周期，更新所述第一驱动电压等级和所述第二驱动电压等级，从所述变幅系数范围随机获取一个变幅系数，将所述第一驱动电压等级设置为原先的第二驱动电压等级乘以所述变幅系数的积，并将所述第二驱动电压等级设置为原先的第一驱动电压等级乘以所述变幅系数的积。可以理解，不同的电压等级，对应于不同的驱动电压。这样，不仅使得像素单元在侧视角下的灰阶亮度曲线接近于正视角下的灰阶亮度曲线的基础上，还能够保证长期运行达到均匀显示的效果，对于显示面板也是一种较好的保护，这样的设计有利于提升画面显示质量。
采用上述驱动方法，能够使得显示面板的每一列(row)像素中，被施加正极性高电压等级(H+)驱动电压的子像素的数量和被施加负极性高电压等级(H-)驱动电压的子像素的数量相等，例如图3中的每一列，代表正极性高电压等级(H+)的子像素和代表负极性高电压等级(H-)的子像素各有3个。高电压等级正负极性的子像素数量相同能够使得V com电压免受寄生电容的影响，从而确保图像信号的正确性，避免发生色偏或画质异常的现象。
在一个实施例中，上述驱动方法还包括：对于同一行的子像素，施加相同极性的驱动电压。这样，使得同一数据线输出的多个电压信号之差维持在较小的范围内，能够避免数据驱动芯片发热或电压信号失真，从而进一步提升各子像素的显示质量。
在一个实施例中，所述驱动方法中，所述对同一所述像素组中的所述第二位置像素单元及所述第三位置像素单元分别施加与所述第一位置像素单元极性相反的驱动电压，包括：对同一所述像素组中的所述第一位置像素单元及所述第二位置像素单元分别施加极性相反的驱动电压；并且对同一所述像素组中的所述第三位置像素单元施加与所述第二位置像素单元极性相同的驱动电压；其中，所述像素单元包括依次排列的第一子像素、第二子像素及第三子像素；所述对同一所述像素组中的所述第一位置像素单元及所述第二位置像素单元分别施加极性相反的驱动电压；对同一所述像素组中的所述第三位置像素单元施加与所述第二位置像素单元极性相同的驱动电压，包括：在 同一像素组中，对所述第一位置像素单元的第一子像素和第三子像素分别施加第一极性的驱动电压，对所述第二位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压，并对所述第三位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压；对所述第一位置像素单元的第二子像素施加第二极性的驱动电压，对所述第二位置像素单元的第二子像素施加第一极性的驱动电压，并对所述第三位置像素单元的第二子像素施加第一极性的驱动电压；其中所述第一极性与所述第二极性互为相反极性；并且，所述驱动方法还包括：在每相邻的两帧显示时间内，对同一所述子像素交替施加极性相反的驱动电压；其中，所述对所述第一像素单元中的子像素和所述第二像素单元中的子像素分别施加不同电压等级的驱动电压，包括：对所述第一像素单元中的子像素施加预设第一电压等级的驱动电压；对所述第二像素单元中的子像素施加预设第二电压等级的驱动电压。
实际应用中，当显示面板为液晶面板时，考虑到直流电场驱动液晶像素容易导致液晶材料发生化学反应并加速电极老化，进而缩短显示面板的寿命，在一个实施例中，显示面板为液晶面板。因此在一个实施例中，为了保护液晶材料及电极，延长显示面板的寿命，对显示面板中的每个子像素进行交流驱动。具体地，对于同一个子像素，在每相邻的两帧显示时间内，分别施加不同极性的驱动电压以达到交流驱动的效果。例如，所述驱动方法还包括：在每相邻的两帧显示时间内，对同一所述子像素交替施加极性相反的驱动电压，或者说，对每一所述子像素，在每一帧显示时间内，施加与上一帧显示时间极性相反的驱动电压。例如，在第m帧显示时间内，对显示面板中的一些子像素施加如图3所示的驱动电压，而在第m+1帧显示时间内，对上述一些子像素施加如图4所示的驱动电压。可见，在每相邻的两帧显示时间内，同一子像素的驱动电压极性发生变化，并且驱动电压等级保持不变。
作为一种实施方式，在驱动显示面板时，对于每个子像素，根据其所属的像素单元确定驱动电压等级，根据其在像素单元中的排列顺序及其所在的像素单元在像素组中的排列顺序确定驱动电压极性，进而根据各子像素的图 像数据、对应的驱动电压极性和等级，得到各子像素的驱动电压，通过数据线将该驱动电压施加至各个子像素。
采用上述显示面板的驱动方法，驱动显示面板分别对如图5a、图5b、图5c、图5d、图5e、图5f、图5g及图5h所示这几种特定的测试画面进行显示，图中填充有黑色斜线的子像素表示该子像素对应的数据信号为暗态信号。经过实验，发现图5a和图5b的闪烁(Flicker)画面至图5h的画面显示无色偏问题，图5c的画面能够避免水平方向的串扰，图5d均无色偏问题，其中图5d表示每隔一个像素单元交替亮/暗显示的画面，图5e表示每隔两个像素单元交替亮/暗显示的画面，图5f表示每隔一个子像素交替亮/暗显示的画面，图5g表示每隔一列子像素交替亮/暗显示的画面，图5h表示每隔一列像素单元交替亮/暗显示的画面。由此可见，本申请实施例的显示面板的驱动方法具有良好的色偏改善效果。

又如，所述像素单元包括依次排列的第一子像素、第二子像素及第三子像素，所述第一驱动单元包括第一驱动子单元及第二驱动子单元。第一驱动子单元用于在同一像素组中，对所述第一位置像素单元的第一子像素和第三子像素分别施加第一极性的驱动电压，对所述第二位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压，并对所述第三位置像素单元的第一子像素和第三子像素分别施加第二极性的驱动电压；第二驱动子单元，用于对所述第一位置像素单元的第二子像素施加第二极性的驱动电压，对所述第二位置像素单元的第二子像素施加第一极性的驱动电压，并对所述第三位置像素单元的第二子像素施加第一极性的驱动电压；其中所述第一极性与所述第二极性互为相反极性。
这样，每一列中，被施加正极性高电压等级(H+)驱动电压的子像素的数量和被施加负极性高电压等级(H-)驱动电压的子像素的数量相等，使得V com电压免受寄生电容的影响，从而确保图像信号的正确性，避免发生色偏或画质异常的现象。
