本发明的驱动信号的补偿方法,包括:
S101、获取每个像素的输出扫描信号与输出数据信号之间的第一相位差。
例如,预先向液晶显示面板输入扫描信号和数据信号,之后再获取每个像素的实际扫描信号的相位和实际数据信号的相位之间的差值,也即第一相位差。该输出扫描信号和输出数据信号为像素的实际的扫描信号和数据信号,也即调整前实际的扫描信号和数据信号。

例如,根据步骤S101获取的相位差对对应像素的初始扫描信号的相位进行调整,以使所述像素的调整后的输出扫描信号与该像素调整后的输出数据信号之间的相位差等于该像素调整后的输入扫描信号与输入数据信号的相位差。
其中该输入扫描信号为驱动芯片提供的扫描信号,也即初始扫描信号。其中该输入数据信号为驱动芯片提供的数据信号,也即初始数据信号。
当所述像素的调整后的输出扫描信号与对应的输出数据信号之间的相位差等于对应像素调整后的输入扫描信号与输入数据信号的相位差时,能够使得在数据信号的切换时,扫描信号为低电平,也即不会出现充电错误的情况。
所述步骤S102包括:
S1021、获取每个像素的所述第一相位差与初始相位差之间的差值。
例如,预先获取每个像素的输出扫描信号与输出数据信号的沿水平方向的相位差,得到第一相位差。之后再获取第一相位差与初始相位差之间的差值。所述初始相位差为所述像素的调整前的输入扫描信号与输入数据信号之间的相位差。
S1022、根据所述差值对每行像素中对应像素的输入扫描信号的相位进行调整。
在具体补偿过程中,分别获取每个像素的第一相位差与初始相位差之间的差值,根据该差值对对应像素的输入扫描信号的相位进行调整。具体地,对每行像素从左到右逐渐减小每个扫描信号的相位。
S103、根据所述第一相位差对对应像素的输入数据信号的相位进行调整,以使所述像素的调整后的输出扫描信号与对应的输出数据信号之间的相位差等于对应像素调整后的输入扫描信号与输入数据信号的相位差。

| Tgf31=Tgd31= Δ t31 | Tgf32=Tgd32= Δ t32 | Tgf33= Tgd33= Δ t33 |
表1
具体地,如表1所示,以液晶显示面板包括9个像素为例,初始相位差为初始扫描信号和初始数据信号之间的相位差。Tgf为每个像素调整后的实际相位差,调整后的实际相位差为调整后的实际的扫描信号和数据信号之间的相位差。Tgd为每个像素的调整后的初始相位差,也即调整后的初始扫描信号和初始数据信号之间的相位差。Tgd11-
Tgd33表示不同位置的像素的调整后的初始相位差,Tgf11- Tgf33表示不同位置的像素调整后的实际相位差,Tgf、Tgd具体如图4所示。
在一实施方式中,当所述第一相位差大于所述初始相位差时,将所述像素的输入扫描信号的相位减小所述差值。当将所述像素的输入扫描信号的相位减小所述差值时,使得每个像素的调整后的输出扫描信号与对应的输出数据信号沿垂直方向的相位差等于对应像素调整后的输入扫描信号与输入数据信号沿垂直方向的相位差。
如图4所示,比如某个像素的T'gf大于T'gd,T'gf为调整前该像素的实际扫描信号和实际数据信号之间的相位差,T'gd为调整前该像素的初始扫描信号和初始数据信号之间的相位差。此时将该像素的初始扫描信号的相位向左移动T'gf—T'gd的差值,从而使得调整后的Tgf等于Tgd。经过补偿后使每个像素的Tgf=Tgd,也即使得每个像素的调整后的实际的扫描信号和实际的数据信号之间的相位差等于调整后的初始扫描信号和初始数据信号的相位差,不同像素的Δt数值可以不相等。
在一实施方式中,当所述第一相位差大于所述初始相位差时,将所述像素的输入数据信号的相位增大所述差值。当将所述像素的输入数据信号的相位增大所述差值时,使得每个像素的调整后的输出扫描信号与对应的输出数据信号沿水平方向的相位差等于对应像素调整后的输入扫描信号与输入数据信号沿水平方向的相位差。
如图4所示,某个像素的T'gf大于T'gd,T'gf为调整前该像素的实际扫描信号和实际数据信号之间的相位差,T'gd为调整前该像素的初始扫描信号和初始数据信号之间的相位差。此时将该像素的初始数据信号的相位向右移动T'gf—T'gd的差值,从而使得调整后的Tgf等于Tgd。经过补偿后使每个像素的Tgf=Tgd,使得每个像素的调整后的实际的扫描信号和数据信号之间的相位差等于调整后的初始扫描信号和数据信号的相位差,不同像素的Δt数值可以不相等。
在另一实施方式中,将每个像素的输入数据信号的相位都增大一设定相位。当将每个像素的输入数据信号的相位都增大一设定相位时,使得每个像素的调整后的输出扫描信号与对应的输出数据信号沿垂直方向的相位差等于对应像素调整后的输入扫描信号与输入数据信号沿垂直方向的相位差。
比如第一列像素中最下方的像素的输入数据信号需要调整m1个相位,才能使得调整后的实际的扫描信号和数据信号之间的相位差等于调整后的初始扫描信号和数据信号的相位差。第二列像素中最下方的像素的输入数据信号需要调整m2个相位,才能使得调整后的实际的扫描信号和数据信号之间的相位差等于调整后的初始扫描信号和初始数据信号的相位差。第三列像素中最下方的像素的输入数据信号需要调整m3个相位,才能使得调整后的实际的扫描信号和实际数据信号之间的相位差等于调整后的初始扫描信号和初始数据信号的相位差。m1、m2、m3中的最大值为m2,将每个像素的初始数据信号的相位向右移动m2个相位,从而使得每个像素调整后的实际扫描信号和实际数据信号之间的相位差等于调整后的初始扫描信号和初始数据信号的相位差。也即m2为该设定相位。
在一实施例中,当所述液晶显示面板包括一栅驱动芯片时,也即液晶显示面板为单边驱动时,对与所述栅驱动芯片之间的距离大于预设距离的像素的输入数据信号的相位或者输入扫描信号的相位进行调整。
具体地,结合表1,第一至三行像素的调整后的相位差分别满足如下关系:Δt11 < Δt12 <
Δt13 ,Δt21 < Δt22 < Δt23 ,Δt31 < Δt32 < Δt33。
第一至三列像素的调整后的相位差分别满足如下关系:Δt11 < Δt21 < Δt31
,Δt12 < Δt22 < Δt32 ,Δt13 < Δt23 < Δt33。
如图5所示,P1’表示扫描信号的脉冲,P11-
P13表示调整后第1行三个像素的数据信号的脉冲,经过调整后,第1行第1列的像素的实际扫描信号11与实际数据信号12之间的相位差为△t11,第1行第2列的像素的实际扫描信号21与实际数据信号22之间的相位差为△t12,第1行第3列的像素的实际扫描信号31与实际数据信号32之间的相位差为△t13。也即经过调整后,每一行像素的相位差从左到右依次增大。每一列的像素的相位差从上到下依次增大。
由于第1行第2列的像素和第1行第3列的像素与源驱动芯片的距离大于第1行第1列的像素与源驱动芯片之间的距离,第1行第1列的像素与源驱动芯片之间的距离为预设距离。因此需要第1行第2列的像素和第1行第3列的像素的驱动信号进行补偿。也即第1行第2列的像素和第1行第3列的像素的T'gf大于T'gd。
在一实施方式中,具体补偿方式为,将第1行第2列的像素的数据信号的相位向右移动L1(也即增大数据信号的相位),将第1行第3列的像素的数据信号的相位向右移动L2+L1,从而使得第1行第2列的像素调整后的沿垂直方向的Tgf等于Tgd,以及第1行第3列的像素调整后的沿垂直方向的Tgf等于Tgd。其余的像素的驱动信号的补偿方式与此相似,以此类推。
在另一实施方式中,具体补偿方式为,将第1行第2列的像素的扫描信号的相位向左移动L1(也即减小扫描信号的相位),将第1行第3列的像素的扫描信号的相位向左移动L2+L1,从而使得第1行第2列的像素调整后的沿水平方向的Tgf等于Tgd,以及第1行第3列的像素调整后沿水平方向的的Tgf等于Tgd。
在另一实施例中,当所述液晶显示面板包括相对设置的第一栅驱动芯片和第二栅驱动芯片,比如液晶显示面板为双边驱动时,对设定像素的输入扫描信号的相位或者输入数据信号的相位进行调整,所述设定像素为与所述第一栅驱动芯片之间的距离大于预设距离且与所述第二栅驱动芯片之间的距离大于预设距离的像素。
具体地,结合表1,当双边驱动时,第一至三行像素的调整后的相位差分别满足如下关系:Δt11 = Δt13
< Δt12,Δt21 = Δt23 < Δt22,Δt31 = Δt33 < Δt32。
第一至三列像素的调整后的相位差分别满足如下关系:Δt11 = Δt31 < Δt21,Δt12 =
Δt32 < Δt22,Δt13 = Δt33 < Δt23 。
如图6所示,P1’表示扫描信号的脉冲,P11、P21、P31表示调整后第1列三个像素的数据信号的脉冲,经过调整后,第1行第1列的像素的实际扫描信号41与实际数据信号42之间的相位差为△t11,第1行第2列的像素的实际扫描信号51与实际数据信号52之间的相位差为△t21,第1行第3列的像素的实际扫描信号61与实际数据信号62之间的相位差为△t31,也即经过调整后,每一行像素的相位差从两侧到中间逐渐增大。每一列像素的相位差从两侧到中间逐渐增大。
由于第1行第2列的像素与源驱动芯片的距离大于第1行第1列的像素与源驱动芯片之间的距离,也大于第1行第3列的像素与源驱动芯片之间的距离,因此需要第1行第2列的像素的驱动信号进行补偿。也即第1行第2列的像素的T'gf大于T'gd。
在一实施方式中,具体补偿方式为,将第1行第2列的像素的数据信号的相位向右移动L3(也即增大数据信号的相位),从而使得第1行第2列的像素调整后的沿垂直方向的Tgf等于Tgd。其余的像素的驱动信号的补偿方式与此相似,以此类推。
在另一实施方式中,具体补偿方式为,将第1行第2列的像素的扫描信号的相位向左移动L3(也即减小扫描信号的相位),从而使得第1行第2列的像素调整后的沿水平方向的Tgf等于Tgd。
