具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的驱动方法及其装置、显示设备进行详细描述。
图1为本公开的一个实施例提供的一种驱动方法的流程图。如图1所示，所述驱动方法包括将显示区域划分为多个矩形分区，在相邻的第一分区与第二分区之间形成第一过渡区域。
图2为在图1所示的实施例中形成过驱动分区的示意图，图3为在图1所示的实施例中形成过渡区域的示意图。如图2和图3所示，根据显示面板表面的温度分布将显示区域划分为多个过驱动分区，其中在相邻的第一分区a与第二分区b之间形成第一过渡区域M2。需要 说明的是，尽管本实施例只描述具有两个过驱动分区的情形，但是本公开也意图包括其它数量的过驱动分区，例如，四个过驱动分区、六个过驱动分区或者八个过驱动分区。
每个过驱动分区对应一个过驱动表，显示面板根据所述过驱动表对对应的过驱动分区进行过驱动处理。所谓过驱动，就是当液晶分子的目标状态的对应电压高于液晶分子当前的电压时，施加一个高于目标状态的电压给液晶分子。当液晶分子的目标状态的对应电压低于液晶分子当前的电压时，就施加一个低于目标状态的电压给液晶分子。这个施加的高于目标状态或低于目标状态的电压称为过驱动电压。
该驱动方法还包括形成第一分区过驱动表和第二分区过驱动表，所述第一分区过驱动表与所述第一分区对应，所述第二分区过驱动表与所述第二分区对应，所述第一分区过驱动表和所述第二分区过驱动表的矩阵形式相同。
在本实施例中，所述第一分区过驱动表与所述第一分区a对应，所述第二分区过驱动表与所述第二分区b对应，所述第一分区过驱动表与所述第二分区过驱动表的矩阵形式相同。
在实际应用中，过驱动可以使液晶分子加速转动，从而缩短液晶分子的灰阶响应时间。至于施加的过驱动电压的具体数值，则通过对应的过驱动表获得。具体为，根据前一帧的灰阶值和当前帧的灰阶值查询过驱动表得到一个过驱动灰阶值，所述过驱动灰阶值与过驱动电压对应。表1为第一分区过驱动表的过驱动灰阶值。表1如下所示：
表1
Figure PCTCN2015091826-appb-000007
表1所示的第一分区过驱动表的矩阵形式为17*17，由于所述第一分区过驱动表与所述第二分区过驱动表的矩阵形式相同，因此所述第二分区过驱动表的矩阵形式也为17*17。
该驱动方法还包括根据第一平滑算法对所述第一分区过驱动表和所述第二分区过驱动表进行运算处理以形成第一平滑过驱动表，所述第一平滑过驱动表与所述第一过渡区域对应。
在本实施例中，所述第一平滑算法的原理为：首先获得一个累加量，然后沿一个特定方向依次对灰阶值进行累加，从而获得第一平滑过驱动表中对应的灰阶值，以实现对过渡区域的平滑过渡。
在本实施例中，所述第一分区过驱动表的第一灰阶值为A，所述第二分区过驱动表的第二灰阶值为B，其中A与B为自然数，所述第一灰阶值与所述第二灰阶值在所述矩阵形式的位置对应。下面对所述“位置对应”进行详细描述，例如，所述第一分区过驱动表为表1，由于所述第一分区过驱动表与所述第二分区过驱动表的矩阵形式相同，因此，所述第二分区过驱动表的矩阵形式也为17*17。参见表1，任取其中一个灰阶值A：行号5为前一帧64与列号8为当前帧112对应的灰阶值126。对应的，灰阶值B为第二分区过驱动表中行号5与列号8 对应的灰阶值。通过上述方式，所述第一灰阶值与所述第二灰阶值在所述矩阵形式的位置相互对应。
下面以第一过渡区域M2为例具体说明形成所述第一平滑过驱动表的过程。图4为在图1所示的实施例中对过渡区域进行平滑处理的示意图。如图4所示，将从所述第一分区a到所述第二分区b的方向定义为第一方向，所述第一方向为箭头方向。计算所述第一过渡区域M2在所述第一方向上的像素单元的个数为n，其中n为自然数。
从所述第一灰阶值A开始，沿所述第一方向所述像素单元的灰阶值依次累加
Figure PCTCN2015091826-appb-000008
以形成所述第一平滑过驱动表。具体来说，位于第1位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000009
位于第2位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000010
位于第3位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000011
位于第n-2位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000012
Figure PCTCN2015091826-appb-000013
位于第n-1位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000014
位于第n位置的像素单元的灰阶值为
Figure PCTCN2015091826-appb-000015
这样，将每个对应的灰阶值求出后就可以形成所述第一平滑过驱动表。
该驱动方法还包括根据所述第一平滑过驱动表驱动所述第一过渡区域。
在本实施例提供的驱动方法中，根据第一平滑算法对相邻的第一分区和第二分区进行平滑处理，以便模糊化所述第一分区与所述第二分区之间的边界，从而能够有效减少或消除多个分区之间的分界现象。
图5为本公开的另一实施例提供的一种驱动方法的流程图，图6为在图5所示的实施例二中形成过驱动分区的示意图，图7为在图5所示的实施例中形成过渡区域的示意图。参见图5-7，根据显示面板表面的温度分布将显示区域划分为多个过驱动分区，所述过驱动分区包括第一分区a、第二分区b、第三分区c和第四分区d，在相邻的所述 第一分区a与所述第二分区b之间、相邻的所述第二分区b与所述第三分区c之间、相邻的所述第三分区c与所述第四分区d之间、相邻的所述第四分区d与所述第一分区a之间形成第一过渡区域，所述第一分区、第二分区、第三分区和第四分区共同限定第二过渡区域。具体来说，所述第一分区a分别与第二分区b和第四分区d相邻设置，所述第三分区c分别与所述第二分区b和所述第四分区d相邻设置，相邻的第一分区a与第四分区d之间形成第一过渡区域M1，相邻的第一分区a与第二分区b之间形成第一过渡区域M2，相邻的第二分区b与第三分区c之间形成第一过渡区域M3，相邻的第三分区c与第四分区d之间形成第一过渡区域M4，所述第一分区a、第二分区b、第三分区c和第四分区d共同限定第二过渡区域F。需要说明的是，关于形成第一过渡区域对应的第一平滑过驱动表的具体内容可参照上述实施例的描述，此处不再赘述。本实施例以第二过渡区域F为例具体说明形成第二平滑过驱动表的过程。
所述驱动方法包括在步骤101处，在形成第一分区过驱动表和第二分区过驱动表的同时，形成第三分区过驱动表和第四分区过驱动表。
在本实施例中，所述第一分区过驱动表与所述第一分区a对应，所述第二分区过驱动表与所述第二分区b对应，所述第三分区过驱动表与所述第三分区c对应，所述第四分区过驱动表与所述第四分区d对应。所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表的矩阵形式相同。
在实际应用中，过驱动可以使液晶分子加速转动，从而缩短液晶分子的灰阶响应时间。至于施加的过驱动电压的具体数值，则通过对应的过驱动表获得。具体为，根据前一帧的灰阶值和当前帧的灰阶值查询过驱动表得到一个过驱动灰阶值，所述过驱动灰阶值与过驱动电压对应。
参见表1，表1所示的第一分区过驱动表的矩阵形式为17*17，由于所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表的矩阵形式相同，因此所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表的矩阵形式也为17*17。
该驱动方法还包括在步骤102处，在根据第一平滑算法对所述第 一分区过驱动表和所述第二分区过驱动表进行运算处理以形成第一平滑过驱动表的同时，根据第二平滑算法对所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表进行运算处理以形成第二平滑过驱动表。
在本实施例中，所述第二平滑过驱动表与所述第二过渡区域对应。所述第二平滑算法的原理为：对所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表中对应的灰阶值取平均值，从而获得第二平滑过驱动表中的灰阶值，以实现对过渡区域的平滑过渡。
参见图3，所述第一分区过驱动表的第一灰阶值为A，所述第二分区过驱动表的第二灰阶值为B，所述第三分区过驱动表的第三灰阶值为C，所述第四分区过驱动表的第四灰阶值为D，其中A、B、C以及D为自然数，所述第一灰阶值、所述第二灰阶值、所述第三灰阶值和所述第四灰阶值在所述矩阵形式的位置对应。下面对所述“位置对应”进行详细描述，例如，所述第一分区过驱动表为表1，由于所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表的矩阵形式相同，因此，所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表的矩阵形式也为17*17。参见表1，任取其中一个灰阶值A：行号5为前一帧64与列号8为当前帧112对应的灰阶值126。对应的，灰阶值B为第二分区过驱动表中行号5与列号8对应的灰阶值，灰阶值C为第三分区过驱动表中行号5与列号8对应的灰阶值，灰阶值D为第四分区过驱动表中行号5与列号8对应的灰阶值。通过上述方式，所述第一灰阶值、所述第二灰阶值、所述第三灰阶值和所述第四灰阶值在所述矩阵形式的位置相互对应。
所述根据第二平滑算法对所述第一分区过驱动表、所述第二分区过驱动表、所述第三分区过驱动表和所述第四分区过驱动表进行运算处理以形成第二平滑过驱动表的步骤包括将所述第二过渡区域的像素单元的灰阶值计算为
Figure PCTCN2015091826-appb-000016
以形成所述第二平滑过驱动表。
该驱动方法还包括在步骤103处，在根据所述第一平滑过驱动表 驱动所述第一过渡区域的同时，根据所述第二平滑过驱动表驱动所述第二过渡区域。
在本实施例中，所述第二过渡区域F对应所述第二平滑过驱动表，显示面板根据所述第二平滑过驱动表对所述第二过渡区域F进行过驱动处理。具体为，根据前一帧的灰阶值和当前帧的灰阶值查询第二平滑过驱动表从而获得一个过驱动灰阶值，所述过驱动灰阶值与过驱动电压对应。所述显示面板根据所述过驱动电压驱动所述第二过渡区域F。
在本实施例提供的驱动方法中，根据第一平滑算法对相邻的各个分区进行平滑处理，以便模糊化各个分区之间的边界，从而能够有效减少或消除多个分区之间的分界现象。
本公开还提供一种驱动装置，包括划分单元、第一形成单元、第二形成单元和驱动单元。所述划分单元用于将显示区域划分为多个矩形分区，在相邻的第一分区与第二分区之间形成第一过渡区域。在本实施例中，显示区域的划分是基于人工调试通过人眼观察实现的。所述划分单元可以包括计数器和寄存器。所述计数器用于将对应的数据线和栅线进行计数，从而形成像素单元的坐标值。所述寄存器用于存储所述坐标值。最后，通过人工调试的方式将显示区域划分为多个矩形分区。
