Description

液晶面板的驱动方法及驱动装置 技术领域
本发明属于液晶显示器技术领域，更具体地说，涉及一种液晶面板的驱动方法及驱动装置。
背景技术
近年来，液晶显示器(LCD)以其体积小、重量轻、显示质量高等优点逐渐替代了以往的阴极射线显像管(CRT)显示器。液晶显示器中的液晶面板所显示的画面由许多阵列排列的像素构成，每一个像素通常由分别显示各种颜色的子像素组成，每一个子像素所显示的亮度由液晶显示器的背光模组的亮度和该液晶面板的子像素的灰阶共同决定。现有的液晶显示器的驱动方法中，最常用的方法是利用背光模组的亮度维持一固定亮度，根据输入的影像资料，分别以不同大小的灰阶电压驱动该液晶面板的每一个子像素内的液晶进行旋转，从而通过液晶分子的旋转角度来决定各个子像素的透光率(即，亮度)，以达到灰阶显示和显像的目的。
随着液晶显示器技术的发展，为了改善液晶显示器的色偏问题，人们提出了液晶面板的分时驱动方法，即，将通过变换得到的液晶面板中的每个子像素的多个实际灰阶值，依次地驱动到液晶面板上以显示多个帧画面。然而，在使用这种驱动方法时，会出现在某一帧画面中，液晶面板的所有子像素的灰阶值都相对较大或相对较小的情况，这样，就会使得液晶面板整体偏亮或偏暗，从而导致显示的画面闪烁。

具体实施方式
现将详细描述本发明的示例性实施例，所述实施例的示例在附图中示出，其中，相同的标号指示相同的部分。以下将通过参照附图来说明所述实施例，以便解释本发明。
应予说明，这里所说的液晶面板包括多个像素，每一像素包括多个颜色的子像素。后述的预定颜色子像素为液晶面板中多个颜色中的任一颜色的子像素。
本发明的示例性实施例的一种液晶面板的驱动方法为对于液晶面板的预定颜色子像素，以连续的n个帧为单位来进行驱动。这里，n为大于1的整数。下面，对驱动预定颜色子像素的任意一个单位的n个帧的步骤进行说明。
图1是示出根据本发明示例性实施例的液晶面板的驱动方法中驱动任意一个单位的n个帧的预定颜色子像素的步骤的流程图。
如图1所示，在步骤S101，确定每个预定颜色子像素分别在n个帧中的原 始灰阶值，从而针对每个预定颜色子像素获得n个原始灰阶值。这里，原始灰阶值为子像素显示一帧画面时原本的灰阶值(例如，在现有技术中驱动液晶面板显示一帧画面时设置给子像素的灰阶值)。可以理解，可通过现有的各种方法获得每个预定颜色子像素的n个原始灰阶值。
在步骤S102，根据步骤S101获得的每个预定颜色子像素的n个原始灰阶值中的至少一个，获取每个预定颜色子像素的n个实际灰阶值。这里，本领域技术人员可利用现有的各种方法来获取所述n个实际灰阶值。
作为示例，根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定颜色子像素的n个实际灰阶值(即，根据任意一个预定颜色子像素自己的n个原始灰阶值中的至少一个来获取自己的n个实际灰阶值)的步骤如图2所示。
图2是示出根据本发明示例性实施例的根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定颜色子像素的n个实际灰阶值的步骤的流程图。
如图2所示，在步骤S201，根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，确定m个索引值，m为大于0的整数。这里，索引值为用来查找后述的显示查找表的灰阶值。索引值的数量可根据n和后述的显示查找表中与每个索引值对应的实际灰阶值的数量来确定。可以理解，可利用现有的各种方法来确定所述m个索引值。
作为示例，可将所述n个原始灰阶值中的任意m个原始灰阶值作为所述m个索引值。
作为另一示例，可首先将所述n个原始灰阶值按预定规则划分为m个组。这里，所述预定规则可根据本领域技术人员的设计经验来进行设置。然后，针对所述m个组中的每个组，确定一个索引值，从而得到所述m个索引值。这里，可通过各种方法来确定所述每个组的索引值。
作为示例，针对所述m个组中的任意一个组，确定一个索引值的步骤可包括：将所述一个组中的原始灰阶值的平均值作为所述一个索引值(即，作为所述一个组的索引值)。具体说来，对所述一个组中的各个原始灰阶值求和，然后再除以所述一个组中的原始灰阶值的数量得到所述平均值，将所述平均值作为所述一个索引值。
另外，针对所述m个组中的任意一个组，确定一个索引值的步骤可包括：
首先，根据所述一个预定颜色子像素的伽马曲线，确定所述一个预定颜色子像素在所述一个组中的各个原始灰阶值时的亮度值。这里，所述伽马曲线为表示所述一个预定颜色子像素的灰阶与亮度关系的曲线，可通过各种测量方法获得伽马曲线。所述伽马曲线可以为归一化后的伽马曲线，但并不限于此，未进行归一化的伽马曲线也可以利用。
其次，计算确定的亮度值的平均值，即，对所述一个预定颜色子像素在所述一个组中的各个原始灰阶值时的亮度值求和，然后再除以所述一个组中的原始灰阶值的数量得到所述平均值。
然后，将所述平均值在所述伽马曲线上对应的灰阶值作为所述一个索引值。
在步骤S202，从所述预定颜色子像素的显示查找表中查找与步骤S201中确定的m个索引值中的每个索引值对应的a个实际灰阶值，以获取所述一个预定颜色子像素的n个实际灰阶值，即，由所述显示查找表中与所述每个索引值对应的a个实际灰阶值构成所述一个预定颜色子像素的n个实际灰阶值。
这里，a×m＝n，所述n个实际灰阶值中的第一组实际灰阶值包括每个索引值对应的a个实际灰阶值中的至少一个，所述n个实际灰阶值中的第二组实际灰阶值包括每个索引值对应的a个实际灰阶值中的未包括到所述第一组实际灰阶值中的其他实际灰阶值，a为大于1的整数。
这里，所述显示查找表可通过现有的各种方法确定。优选地，获得预定颜色子像素的显示查找表的步骤如图3所示。
图3是示出根据本发明示例性实施例的获得预定颜色子像素的显示查找表的步骤的流程图。
如图3所示，在步骤S301，分别获取正视情况下和斜视情况下的所述预定颜色子像素在所述液晶面板的灰阶值的取值范围内各个灰阶值下的实际亮度值。这里，所述正视为以与液晶面板的垂直方向呈0度的视角观察液晶面板。所述斜视为以与液晶面板的垂直方向呈大约60度左右的视角观察液晶面板。灰阶值的取值范围由液晶面板的不同而不同，当液晶面板为8比特的液晶面板时(即，使用8位二进制数来表示灰阶值)，所述取值范围为[0，255]，当液晶面板为10比特的液晶面板时(即，使用10位二进制数来表示灰阶值)，所述取值范围为[0,1023]。可以理解，可通过现有的各种方法获取所述实际亮度值。
作为示例，可通过分别测量正视情况下和斜视情况下的所述预定颜色子像素的伽马曲线来获取正视情况下和斜视情况下的所述预定颜色子像素在所述取值范围内各个灰阶值下的实际亮度值。所述伽马曲线为表示所述预定颜色子像素的灰阶与亮度关系的曲线。这里，可通过现有的各种方法来测量所述伽马曲线。
在步骤S302，分别计算正视情况下和斜视情况下的所述预定颜色子像素在所述取值范围内各个灰阶值下的理论亮度值。这里，可通过现有的各种计算方法来计算所述理论亮度值。
作为示例，可通过下式计算在任意一种视角情况下的所述预定颜色子像素在所述取值范围内的任意一个灰阶值g下的理论亮度值：
Lv(g)＝Lv(gmax)′×(g/gmax)γ           (1)
这里，γ为预定伽马值，Lv(g)为在所述一种视角情况下的所述预定颜色子像素在所述一个灰阶值g时的理论亮度值，Lv(gmax)′为在所述一种视角情况下的所述预定颜色子像素在所述取值范围内的最大灰阶值gmax时的实际亮度值，这里，所述一种视角为正视或斜视。
在计算正视情况下所述预定颜色子像素在所述取值范围内的任意一个灰阶值g下的理论亮度值时，将所述一个灰阶值g、所述取值范围内的最大灰阶值gmax、预定伽马值γ代入式(1)，并将正视情况下的所述预定颜色子像素在最大灰阶值gmax时的实际亮度值Lv(gmax)′代入即可得到正视情况下的所述预定颜色子像素在所述一个灰阶值g下的理论亮度值。基于此，可计算正视情况下所述预定颜色子像素在所述取值范围内的各个灰阶值下的理论亮度值。
在计算斜视情况下所述预定颜色子像素在所述取值范围内的任意一个灰阶值g下的理论亮度值时，将所述一个灰阶值g、所述取值范围内的最大灰阶值gmax、预定伽马值γ代入式(1)，并将斜视情况下的所述预定颜色子像素在最大灰阶值gmax时的实际亮度值Lv(gmax)′代入即可得到斜视情况下的所述预定颜色子像素在所述一个灰阶值g下的理论亮度值。基于此，可计算斜视情况下所述预定颜色子像素在所述取值范围内的各个灰阶值下的理论亮度值。
这里，预定伽马值γ可以为2.2，但并不限于此，可根据实际情况进行设定。最大灰阶值gmax为所述取值范围内的最大值，可以为255或1023，但并不限于此， 可根据液晶面板的实际参数来确定。
在步骤S303，根据步骤S301获取的各个实际亮度值和步骤S302计算的各个理论亮度值，确定与作为索引值的所述取值范围内的每个灰阶值对应的满足预定条件的a个实际灰阶值，即，对于作为索引值的所述取值范围内的每个灰阶值都可确定a个实际灰阶值与之对应，且所述每个灰阶值与所述a个实际灰阶值之间满足预定条件。对于所述预定条件，本领域技术人员可根据经验进行设置。
优选地，作为索引值的所述取值范围内的任意一个灰阶值g与对应的实际灰阶值gH和gL满足如下预定条件：
min y＝[Lv正(g)+Lv正(g)-Lv正(gH)′-Lv正(gL)′]2+[Lv斜(g)+Lv斜(g)-Lv斜(gH)′-Lv斜(gL)′]2       (2)
这里，a＝2，Lv正(g)、Lv斜(g)分别为正视情况下和斜视情况下的所述预定颜色子像素在所述一个灰阶值g时的理论亮度值，Lv正(gH)′、Lv斜(gH)′分别为正视情况下和斜视情况下的所述预定颜色子像素在实际灰阶值gH时的实际亮度值，Lv正(gL)′、Lv斜(gL)′分别为正视情况下和斜视情况下的所述预定颜色子像素在实际灰阶值gL时的实际亮度值。
由此，可确定与所述取值范围内的每个索引值对应的满足式(2)的两个实际灰阶值gH和gL。
这里，与每个索引值对应的实际灰阶值的数量可根据应用情况来设置。
在步骤S304，基于步骤S303确定的所述取值范围内的每个索引值与实际灰阶值的对应关系得到所述显示查找表。
返回图2，在利用图3所示的方法获得所述预定颜色子像素的显示查找表后，即可从所述显示查找表中查找与步骤S201确定的m个索引值中的每个索引值对应的a个实际灰阶值，从而获取所述一个预定颜色子像素的a×m＝n个实际灰阶值。这里，所述n个实际灰阶值中的第一组实际灰阶值包括每个索引值对应的a个实际灰阶值中的至少一个，所述n个实际灰阶值中的第二组实际灰阶值包括每个索引值对应的a个实际灰阶值中的未包括到所述第一组实际灰阶值中的其他实际灰阶值。
作为示例，在a＝2时，所述n个实际灰阶值中的第一组实际灰阶值包括每 个索引值对应的2个实际灰阶值中的相对较大的一个实际灰阶值，即，将m个索引值中的任意一个索引值对应的2个实际灰阶值中的相对较大的一个实际灰阶值作为所述第一组实际灰阶值之一，则得到由m个相对较大的实际灰阶值构成的所述第一组实际灰阶值。
所述n个实际灰阶值中的第二组实际灰阶值包括每个索引值对应的2个实际灰阶值中的相对较小的一个实际灰阶值。即，将m个索引值中的任意一个索引值对应的2个实际灰阶值中的相对较小的一个实际灰阶值作为所述第二组实际灰阶值之一，则得到由m个相对较小的实际灰阶值构成的所述第二组实际灰阶值。
以上，根据图2所示的方法可以获取每个预定颜色子像素的n个实际灰阶值。
返回图1，对于步骤S102，作为获取任意一个预定颜色子像素的n个实际灰阶值的方法的另一示例，根据步骤S101获得的每个预定颜色子像素的n个原始灰阶值中的至少一个，获取任意一个预定颜色子像素的n个实际灰阶值的步骤如图4所示。
图4是示出根据本发明示例性实施例的根据每个预定颜色子像素的n个原始灰阶值中的至少一个，获取任意一个预定颜色子像素的n个实际灰阶值的步骤的流程图。
如图4所示，在步骤S401，根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定颜色子像素的第一组实际灰阶值(即，根据所述一个预定颜色子像素自己的n个原始灰阶值中的至少一个来获取自己的第一组实际灰阶值)。这里，可通过各种现有的方法来获取所述第一组实际灰阶值。
优选地，可通过图5所示的方法来获取所述第一组实际灰阶值。
图5是示出根据本发明示例性实施例的根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定颜色子像素的第一组实际灰阶值的步骤的流程图。
如图5所示，在步骤S501，根据任意一个预定颜色子像素的n个原始灰阶值中的至少一个，确定m个索引值，m为大于0的整数。由于步骤S501与步骤S201都是根据一个预定颜色子像素的n个原始灰阶值中的至少一个，确定m个 索引值，其方法相同，此处不再赘述。
在步骤S502，从所述预定颜色子像素的显示查找表中查找与所述m个索引值中的每个索引值对应的a个实际灰阶值，以得到n个实际灰阶值。这里，a为大于1的整数。所述显示查找表的获得方法与步骤S202中的相同，此处不再赘述。
在利用图3所示的方法获得所述预定颜色子像素的显示查找表后，即可从所述显示查找表中查找与步骤S501确定的m个索引值中的每个索引值对应的a个实际灰阶值，从而得到a×m＝n个实际灰阶值。
在步骤S503，从步骤S502得到的所述n个实际灰阶值中，提取出第一组实际灰阶值作为所述一个预定颜色子像素的第一组实际灰阶值。
这里，a×m＝n，所述n个实际灰阶值中的第一组实际灰阶值包括每个索引值对应的a个实际灰阶值中的至少一个，a为大于1的整数。
作为示例，在a＝2时，所述n个实际灰阶值中的第一组实际灰阶值包括所述每个索引值对应的2个实际灰阶值中的相对较大的一个实际灰阶值，即，将m个索引值中的任意一个索引值对应的2个实际灰阶值中的相对较大的一个实际灰阶值作为所述第一组实际灰阶值之一，则得到由m个相对较大的实际灰阶值构成的所述第一组实际灰阶值。
返回图4，在步骤S402，根据所述一个预定颜色子像素的一个相邻的预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定颜色子像素的第二组实际灰阶值(即，所述一个预定颜色子像素自己的第二组实际灰阶值根据与其相邻的一个预定颜色子像素的n个原始灰阶值中的至少一个来获取)。
这里，所述一个预定颜色子像素的一个相邻的预定颜色子像素可以为与所述一个预定颜色子像素相邻的多个预定颜色子像素中的任意一个，也可以为所述液晶面板中的除了所述一个预定颜色子像素之外的任意一个预定颜色子像素。本领域技术人员可根据经验来选择所述一个相邻的预定颜色子像素。可以理解，可通过各种现有的方法来获取所述第二组实际灰阶值。
优选地，可通过图6所示的方法来获取所述第二组实际灰阶值。
图6是示出根据本发明示例性实施例的根据任意一个预定颜色子像素的一个相邻的预定颜色子像素的n个原始灰阶值中的至少一个，获取所述一个预定 颜色子像素的第二组实际灰阶值的步骤的流程图。
如图6所示，在步骤S601，根据所述一个相邻的预定颜色子像素的n个原始灰阶值中的至少一个，确定m个索引值，m为大于0的整数。这里，可利用现有的各种方法来确定所述m个索引值。
作为示例，可将所述一个相邻的预定颜色子像素的n个原始灰阶值中的任意m个原始灰阶值作为所述m个索引值。
作为另一示例，可首先将所述一个相邻的预定颜色子像素的n个原始灰阶值按预定规则划分为m个组。这里，所述预定规则可根据本领域技术人员的设计经验来进行设置。然后，针对所述m个组中的每个组，确定一个索引值，从而得到所述m个索引值。这里，可通过各种方法来确定所述每个组的索引值。
作为示例，针对所述m个组中的任意一个组，确定一个索引值的步骤可包括：将所述一个组中的原始灰阶值的平均值作为一个索引值(即，作为所述一个组的索引值)。具体说来，对所述一个组中的各个原始灰阶值求和，然后再除以所述一个组中的原始灰阶值的数量得到所述平均值，将所述平均值作为所述一个索引值。
另外，针对所述m个组中的任意一个组，确定一个索引值的步骤可包括：
首先，根据所述一个相邻的预定颜色子像素的伽马曲线，确定所述一个相邻的预定颜色子像素在所述一个组中的各个原始灰阶值时的亮度值。这里，所述伽马曲线为表示所述一个相邻的预定颜色子像素的灰阶与亮度关系的曲线，可通过各种测量方法获得伽马曲线。所述伽马曲线可以为归一化后的伽马曲线，但并不限于此，未进行归一化的伽马曲线也可以利用。
其次，计算确定的亮度值的平均值，即，对所述一个相邻的预定颜色子像素在所述一个组中的各个原始灰阶值时的亮度值求和，然后再除以所述一个组中的原始灰阶值的数量得到所述平均值。
然后，将所述平均值在所述伽马曲线上对应的灰阶值作为所述一个索引值。
在步骤S602，从所述预定颜色子像素的显示查找表中查找与所述m个索引值中的每个索引值对应的a个实际灰阶值，以得到n个实际灰阶值。这里，a为大于1的整数。所述显示查找表的获得方法与步骤S202和步骤S502中的相同，此处不再赘述。
在利用图3所示的方法获得所述预定颜色子像素的显示查找表后，即可从所述显示查找表中查找与步骤S601确定的m个索引值中的每个索引值对应的a个实际灰阶值，从而得到a×m＝n个实际灰阶值。
在步骤S603，从步骤S602得到的所述n个实际灰阶值中，提取出第二组实际灰阶值作为所述一个预定颜色子像素的第二组实际灰阶值。
这里，a×m＝n，所述n个实际灰阶值中的第二组实际灰阶值包括每个索引值对应的a个实际灰阶值中的至少一个，a为大于1的整数。
作为示例，在a＝2时，所述n个实际灰阶值中的第二组实际灰阶值包括每个索引值对应的2个实际灰阶值中的相对较小的一个实际灰阶值，即，将m个索引值中的任意一个索引值对应的2个实际灰阶值中的相对较小的一个实际灰阶值作为所述第二组实际灰阶值之一，则得到由m个相对较小的实际灰阶值构成的所述第二组实际灰阶值。
由根据图5的方法获取的第一组实际灰阶值和根据图6的方法获取的第二组实际灰阶值一块构成所述一个预定颜色子像素的n个实际灰阶值。
返回图1，在步骤S103，在每个帧中，将每个预定颜色子像素的实际灰阶值之一作为最终灰阶值来驱动每个预定颜色子像素。这里，任意一个预定颜色子像素在一个单位的n个连续帧中的每个帧的实际灰阶值为不同的实际灰阶值。即，将步骤S102获取的每个预定颜色子像素的n个实际灰阶值分别作为每个预定颜色子像素显示一个单位的每个帧时的最终灰阶值。这里，最终灰阶值是指液晶面板最终显示时的子像素的灰阶值。
这里，在每个帧中，针对第一部分的预定颜色子像素中的每个预定颜色子像素，将自己的第一组实际灰阶值之一作为最终灰阶值来进行驱动，针对第二部分的预定颜色子像素的每个预定颜色子像素，将自己的第二组实际灰阶值之一作为最终灰阶值来进行驱动，即，将液晶面板中的预定颜色子像素划分为两个部分，将属于第一部分的每个预定颜色子像素以自己的n个实际灰阶值中的属于第一组实际灰阶值中的一个来进行驱动，将属于第二部分的每个预定颜色子像素以自己的n个实际灰阶值中的属于第二组实际灰阶值中的一个来进行驱动。
作为示例，在n＝4，a＝2时，m＝2，即，有2个索引值，根据式(2)，2个索引值分别对应的实际灰阶值gH分别为gH1、gH2，2个索引值分别对应的实际灰 阶值gL分别为gL1、gL2，则4个实际灰阶值中的第一组实际灰阶值包括实际灰阶值gH1和gH2，4个实际灰阶值中的第二组实际灰阶值包括实际灰阶值gL1和gL2。
此时，每个预定颜色子像素在一个单位的4个连续帧中的4个实际灰阶值分别为gH1、gL1、gH2、gL2。在驱动液晶面板显示所述4个连续帧中的每个帧时，针对第一部分的预定颜色子像素中的每个预定颜色子像素，将自己的第一组实际灰阶值gH1和gH2之一作为最终灰阶值来进行驱动，针对第二部分的预定颜色子像素的每个预定颜色子像素，将自己的第二组实际灰阶值gL1和gL2之一作为最终灰阶值来进行驱动。
在一个示例中，所述第一部分的预定颜色子像素中的每个预定颜色子像素在一个单位的4个连续帧中的最终灰阶值可依次为自己的实际灰阶值gH1、gH2、gL1、gL2，所述第二部分的预定颜色子像素中的每个预定颜色子像素在所述4个连续帧中的最终灰阶值可依次为自己的实际灰阶值gL1、gL2、gH1、gH2。
所述第一部分和所述第二部分可以为液晶面板中的不同的任意两个部分。为了进一步提高液晶面板的显示效果，作为一个优选示例，第一部分的预定颜色子像素可为奇数列中的预定颜色子像素，第二部分的预定颜色子像素可为偶数列中的预定颜色子像素，如图7所示。
