具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
图1为一实施例中的液晶显示器件的驱动方法的流程图。该液晶显示器件可以为TN、OCB、VA型、曲面液晶显示器件，但并不限于此。该液晶显示器件可以运用直下背光，背光源可以为白光、RGB三色光源、RGBW四色光源或者RGBY四色光源，但并不限于此。该驱动方法同样适用于液晶显示器件的显示面板为曲面面板时的情形。在本实施例中，液晶显示器件的背光区划分为多个背光分区，如图2所示。图2中，90表示背光部件(或者背光模组)。
参见图1，该方法包括以下步骤：
S110，将每一幅画面使用两帧图像依序显示。
将每一幅画面frame_N(也即典型的一帧画面)使用两帧图像依序显示，也即将一幅画面在时序上分割为两帧图像。通过时序上对画面进行分割，可以实现帧频的倍频，也即将原来的60Hz倍频至120Hz。两帧图像分别为第一帧图像(frame_N-1)和第二帧图像(frame_N-2)。通过第一帧图像和第二帧图像相互补偿向用户显示与输入信号对应的画面。在本实施例中，每一帧图像上的相邻两个子像素的驱动电压为一高一低，并且每一个子像素在第一帧图像中的驱动电压和在第二帧图像中的驱动为一高一低。也即，第一帧图像的各子像素的驱 动电压反转形成第二帧图像的各子像素的驱动电压。第一帧图像和第二帧图像中的每一子像素的驱动电压可以利用查找表(LUT，Look UP Table)查找获取。具体地，液晶显示器件内会预先将查找表存储在硬件帧缓存(frame buffer)里面。查找表为画面输入信号和与该输入信号对应的第一帧图像、第二帧图像的每一子像素的驱动电压的对应关系表。以8bit驱动信号来看，每一R/G/B输入信号输入颜色灰度值0～255对应有256对高低电压信号，共有3*256对高电压信号R TH/G TH/B TH与低电压信号R TL/G TL/B TL。因此，根据输入信号中每一子像素的颜色灰度值可以查找对应的高驱动电压和对应的低驱动电压，从而将该高驱动电压驱动第一帧图像中对应的子像素且将该低驱动电压驱动第二帧图像中对应的子像素，或者将该低驱动电压驱动第一帧图像中对应的子像素且将该高驱动电压驱动第二帧图像中对应的子像素，同时相邻两个子像素采用高低驱动电压相间的驱动方式进行驱动，如图3所示。其中，图4为图3中的第一帧中的局部放大图，图5为图3中第二帧中的局部放大图。
S120，根据每个背光分区对应的第一帧图像区域和第二帧图像区域的驱动电压确定每个背光分区的背光亮度调节信号。
背光亮度调节信号用于对下一幅画面中的两帧图像进行背光亮度调节，以降低画面的视角色偏。背光亮度调节信号为成组信号(A M_P1和A M_P2，P表示目标颜色子像素)，以分别调节第一帧图像和第二帧图像对应的背光分区的背光亮度。并且，背光亮度调节信号的组数与颜色子像素的种类相同，以对各种颜色子像素进行独立的背光亮度控制。例如，在本实施例中，颜色子像素包括红色子像素(R子像素)、绿色子像素(G子像素)和蓝色子像素(B子像素)，因此每一组背光亮度调节信号均包括R子像素背光亮度调节信号组、G子像素背光亮度调节信号组和B子像素背光亮度调节信号，以对各背光分区内的各种颜色 子像素进行独立的背光亮度调节控制。
在本实施例中，确定背光亮度调节信号的流程如图6所示，包括S210和S220。
S210，统计每个背光分区对应的第一帧图像区域和第二帧图像区域中各种颜色子像素的平均驱动电压。
每个背光分区内对应的第一帧图像区域中的每种颜色子像素的平均驱动电压的计算公式如下：
P M_ave1＝Ave(P M＿n_TL，P M＿n+1_TH，P M_n+2_TL，…)，n＝1，2，3……。
其中，P表示目标颜色子像素，M表示背光分区的序号，ave1表示第一帧图像的平均驱动电压值；n表示P子像素在M背光分区中的顺序编号。
具体地，各种颜色子像素的平均驱动电压的计算如下：
R M_ave1＝Ave(R M＿n_TL，R M＿n+1_TH，R M_n+2_TL，…)，n＝1，2，3…；
G M_ave1＝Ave(G M＿n_TH，G M＿n+1_TL，G M_n+2_TH，…，n＝1，2，3…；
B M_ave1＝Ave(B M＿n_TL，B M＿n+1_TH，B M_n+2_TL，…，n＝1，2，3…。
S220，根据各背光分区的平均驱动电压、基准背光亮度信号和基准驱动电压求取背光亮度调节信号。
基准背光亮度信号是指不做高低电压补偿时(也即典型的驱动方式)所需的背光亮度信号。基准驱动电压是指不做高低电压补偿时的各种子像素的驱动电压。由于每个分区内的各种颜色子像素的对应的背光源为独立控制，因此需要求取每个分区内的各种颜色子像素对应的背光源的背光亮度调节信号。每个背光分区M中的每一种颜色子像素的背光亮度调节信号的计算公式如下：
A M_P1*P M_ave1＝A M_P2*P M_ave2；
2*A M_P*P M_ave＝A M_P1*P M_ave1+A M_P2*P M_ave2。
其中，P表示目标颜色子像素；M表示背光分区的序号。A M_P1表示用于对 下一幅画面的第一帧图像对应的背光分区M内的P子像素的背光源进行背光亮度调节的背光亮度调节信号。A M_P2表示用于对下一幅画面的第二帧图像对应的背光分区M内的P子像素的背光源进行背光亮度调节的背光亮度调节信号。P M_ave1表示当前一幅画面的第一帧图像对应的背光分区M内的P子像素的驱动电压的平均值。在本实施例中，由于子像素的驱动电压与输入信号(也即对应颜色的灰阶值)匹配，从而使得驱动电压的平均值能作为该颜色子像素的视角亮度的评价参数。P M_ave2表示当前一幅画面的第二帧图像对应的背光分区M内的P子像素的驱动电压的平均值。A M_P表示当前一幅画面的图像对应的背光分区M内的P子像素的基准背光亮度信号。P M_ave表示当前一幅画面的图像上与背光分区M对应的帧图形区域内的P子像素的基准驱动电压的平均值。具体地，P M_ave1＝Ave(P n+P n+1+P n+2+…)，n＝1，2，3……。
在本实施例中，每一帧图像的一个像素包括R子像素、G子像素和B子像素。因此，对应的需要求取每个背光分区中各种颜色子像素的背光源的背光亮度调节信号，具体如下：
背光分区M内的R子像素的背光亮度调节信号A M_R1和A M_R2的求取公式为
A M_R1*R M_ave1＝A M_R2*R M_ave2；
2*A M_R*R M_ave＝A M_R1*R M_ave1+A M_R2*R M_ave2；
背光分区M内的G子像素的背光亮度调节信号A M_G1和A M_G2的求取公式为
A M_G1*G M_ave1＝A M_G2*G M_ave2；
2*A M_G*G M_ave＝A M_G1*G M_ave1+A M_G2*G M_ave2；
背光分区M内的B子像素的背光亮度调节信号A M_B1和A M_B2的求取公式 为
A M_B1*B M_ave1＝A M_B2*B M_ave2；
2*A M_B*B M_ave＝A M_B1*B M_ave1+A M_B2*B M_ave2。
S130，根据每个背光分区的背光亮度调节信号对下一幅画面的各帧图像中的相应背光分区内的各种颜色子像素的背光源进行独立的亮度调节。
调节过程中，根据A M_R1、A M_G1和A M_B1对下一幅画面中的第一帧图像的相应背光分区M内的R子像素、G子像素和B子像素的背光源进行独立调节，并根据A M_R2、A M_G2和A M_B2对下一幅画面中的第二帧图像的相应背光分区M内的R子像素、G子像素和B子像素的背光源进行独立调节，以使得补偿后的画面亮度与不进行高低电压补偿(也即典型驱动)时的画面亮度表现相同。通过独立的背光源控制，可以减少驱动时高低电压切换差异造成肉眼可视的闪烁不适现象，有效改善液晶显示器件在大视角折射率不匹配造成的色偏缺点。
上述液晶显示器件的驱动方法，将每一幅画面使用两帧图像依序显示，每一帧图像均采用高低相间的电压信号进行驱动，且第一帧图像和第二帧图像的高低驱动电压反转，并根据各驱动电压生成下一幅画面的背光亮度调节信号，以对下一幅画面的各帧图像中的相应背光分区内的各种颜色子像素的背光源进行独立的背光调节。上述驱动方法，辅以各背光分区M亮度的补偿，不仅维持整体面板亮度与不补偿的典型驱动亮度没有变化，还可以实现Low color shift视角补偿效果，又可以避免原先驱动时高低电压切换差异造成肉眼可视的闪烁不适现象，有效改善液晶显示器件在大视角折射率不匹配造成的色偏缺点。上述驱动方法可以实现时域和空间域上的配合驱动。并且，通过采用上述驱动方法，液晶显示器件的像素不需要再分为主要和次要子像素，从而可以大大降低显示面板的工艺复杂度，且大大提升了液晶显示面板的穿透率和解析度，减少了背 光成本的设计。
本申请还提供一种液晶显示器件，如图7所示。该液晶显示器件可以执行上述驱动方法。该液晶显示器件包括显示部件710、背光部件720、还包括驱动部件730、背光控制部件740和背光调节部件750。其中，显示部件710和驱动部件730可以集成在显示面板770上，背光部件720、背光控制部件740和背光调节部件750则可以集成在背光模组780上。可以理解，各部件的集成方式并不限于此。
显示部件710可以采用TN、OCB、VA型TFT显示面板，但并不限于此。显示部件710可以为具有曲面面板的显示部件。
背光部件720用于提供背光。背光部件720可以运用直下背光，背光源可以为白光、RGB三色光源、RGBW四色光源或者RGBY四色光源，但并不限于此。背光部件720的背光区划分为多个背光分区，如图2所示。
驱动部件730与显示部件710连接。驱动部件730用于将每一幅画面使用两帧图像显示。两帧图像分别为第一帧图像和第二帧图像。通过第一帧图像和第二帧图像相互补偿向用户显示与输入信号对应的画面。在本实施例中，每一帧图像上的相邻两个子像素的驱动电压为一高一低，并且每一个子像素在第一帧图像中的驱动电压和在第二帧图像中的驱动为一高一低。也即，第一帧图像的各子像素的驱动电压反转形成第二帧图像的各子像素的驱动电压。驱动部件730驱动各子像素的驱动电压可以利用查找表查找获取。具体地，液晶显示器件内会预先将查找表存储在硬件帧缓存里面。该查找表为输入信号和与该输入信号对应的第一帧图像、第二帧图像的每一子像素的驱动电压的对应关系表。驱动部件730包括时序控制电路731(TCON，timing controller的缩写)。在一实施例中，该液晶显示器件还包括存储器件760，用于存储该查找表。
背光控制部件740与驱动部件730连接。背光控制部件740用于根据每个背光分区对应的第一帧图像区域和第二帧图像区域的驱动电压确定每个背光分区的背光亮度调节信号。背光亮度调节信号为成组信号(A M_P1和A M_P2，P表示目标颜色子像素)，以分别调节第一帧图像和第二帧图像的对应背光分区的背光亮度。并且，背光亮度调节信号的组数与颜色子像素的种类相同，以对各种颜色子像素进行独立的背光亮度控制。例如，在本实施例中，颜色子像素包括红色子像素(R子像素)、绿色子像素(G子像素)和蓝色子像素(B子像素)，因此每一组背光亮度调节信号均包括R子像素背光亮度调节信号组、G子像素背光亮度调节信号组和B子像素背光亮度调节信号，以对各背光分区内的各种颜色子像素进行独立的背光亮度调节控制。
背光控制部件740包括统计单元742和计算单元744，如图8所示。其中，统计单元742计算每个背光分区内对应的第一帧图像区域中的每种颜色子像素的平均驱动电压的公式如下：
P M_ave1＝Ave(P M＿n_TL，P M＿n+1_TH，P M_n+2_TL，…)，n＝1，2，3……。
其中，P表示目标颜色子像素，M表示背光分区的序号，ave1表示第一帧图像的平均驱动电压值；n表示P子像素在M背光分区中的顺序编号。
具体地，各种颜色子像素的平均驱动电压的计算如下：
R M_ave1＝Ave(R M＿n_TL，R M＿n+1_TH，R M_n+2_TL，…)，n＝1，2，3…；
G M_ave1＝Ave(G M＿n_TH，G M＿n+1_TL，G M_n+2_TH，…，n＝1，2，3…；
B M_ave1＝Ave(B M＿n_TL，B M＿n+1_TH，B M_n+2_TL，…，n＝1，2，3…。
计算单元744用于根据各背光分区的平均驱动电压、基准背光亮度信号和基准驱动电压求取背光亮度调节信号。基准背光亮度信号是指不做高低电压补偿时(也即典型的驱动方式)所需的背光亮度信号。基准驱动电压是指不做高 低电压补偿时的各种子像素的驱动电压。由于每个分区内的各种颜色子像素的对应的背光源为独立控制，因此需要求取每个分区内的各种颜色子像素对应的背光源的背光亮度调节信号。每个背光分区M中的每一种颜色子像素的背光亮度调节信号的计算公式如下：
A M_P1*P M_ave1＝A M_P2*P M_ave2；
2*A M_P*P M_ave＝A M_P1*P M_ave1+A M_P2*P M_ave2。
其中，P表示目标颜色子像素；M表示背光分区的序号。A M_P1表示用于对下一幅画面的第一帧图像对应的背光分区M内的P子像素的背光源进行背光亮度调节的背光亮度调节信号。A M_P2表示用于对下一幅画面的第二帧图像对应的背光分区M内的P子像素的背光源进行背光亮度调节的背光亮度调节信号。P M_ave1表示当前一幅画面的第一帧图像对应的背光分区M内的P子像素的驱动电压的平均值。在本实施例中，由于子像素的驱动电压与输入信号(也即对应颜色的灰阶值)匹配，从而使得驱动电压的平均值能作为该颜色子像素的视角亮度的评价参数。P M_ave2表示当前一幅画面的第二帧图像对应的背光分区M内的P子像素的驱动电压的平均值。A M_P表示当前一幅画面的图像对应的背光分区M内的P子像素的基准背光亮度信号。P M_ave表示当前一幅画面的图像上与背光分区M对应的帧图形区域内的P子像素的基准驱动电压的平均值。具体地，P M_ave1＝Ave(P n+P n+1+P n+2+…)，n＝1，2，3……。
背光调节部件750分别与背光控制部件740和背光部件720连接。背光调节部件750用于根据每个背光分区的背光亮度调节信号对下一幅画面的各帧图像中对应的背光分区内的各种颜色子像素的背光源进行独立的亮度调节，以使得补偿后的画面亮度与不进行高低电压补偿时的画面亮度表现相同。
进一步地，再参考图9、图10所示，本实施例进一步提供这种液晶显示器 件的控制电路结构。液晶显示器件800还包括显示区860和围设于所述显示区860四周的非显示区870。
所述显示区860设置有像素阵列，每个像素单元晶体管阵列基板(图中未显示)；所述非显示区870设置有：所述驱动部件830以及源极控制芯片871和栅极控制芯片872，所述驱动部件830和所述源极控制芯片871和所述栅极控制芯片872位于所述显示区860的同一侧。
其中，所述源极控制芯片871通过数据线与所述晶体管阵列基板中的晶体管的源极(图中未显示)电性连接；所述栅极控制芯片872通过扫描线(图中未显示)与所述晶体管的栅极(图中未显示)电性连接。
具体地，栅极控制芯片872包括第一栅极控制芯片872a和第二栅极控制芯片872b。第一栅极控制芯片872a和第二栅极控制芯片872b分别对薄膜晶体管的两个栅极进行控制。第一栅极控制芯片872a、源极控制芯片871和第二栅极控制芯片872b设置在显示区860的同一侧，并且沿显示区860的同一侧依次并列设置在非显示区870上。薄膜晶体管阵列基板上的每一排横向薄膜晶体管的数量与每一列纵向薄膜晶体管的数量不相同。第一栅极控制芯片872a、源极控制芯片871和第二栅极控制芯片872b沿薄膜晶体管数量多的一向依次并列设置。在本实施例中，液晶显示屏为长条屏，第一栅极控制芯片872a、源极控制芯片871和第二栅极控制芯片872b位于显示区860的横向侧。显示区860的其他三侧的非显示区870无需预留芯片的位置，因此非显示区870的对应区域的宽度可以减少，从而宽度D3和宽度D4可以按照需求缩小到目标宽度，满足了液晶显示屏窄边框的需求。同时，第一栅极控制芯片872a、第二栅极控制芯片872b和源极控制芯片871设置在同一侧，源极控制芯片和栅极控制芯片可以在同一道邦定工序中进行邦定，进而减少一道邦定工序，可以降低制作成本同时还可 以提高生产效率。
