具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开一部分实施例，而不是全部实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开提供的像素充电补偿的检测方法、像素充电补偿的检测装置、像素充电的补偿方法以及像素充电的补偿装置可以解决随着分辨率、像素密度及画面刷新率的不断提高的同时，不同位置上像素的充电差异增大，液晶显示面板易出现亮度不均匀的问题。
参见图1，图1是本公开的像素充电补偿的检测方法的流程图。该检测方法可以由本公开下面提到的像素充电补偿的检测装置执行。如图1所示，该检测方法可以包括以下步骤101-105。
步骤101、将显示面板的显示区域按照多个扫描线的排列方向划分为至少两个补偿区域，其中，每一所述补偿区域中具有与至少一条扫描线连接的多个像素。
该步骤中，检测装置可以先对显示面板的显示区域进行划分，按照显示区域中多个扫描线的排列方向，将显示区域划分为至少两个补偿区域。每一个补偿区域中包括至少一条扫描线，并且具有与所述至少一条扫描线连接的多个像素。
其中，所述检测装置可以是与包含所述显示面板的显示装置分开，即所述检测装置是所述显示装置之外额外设置的第三方检测装置。所述检测装置也可以与所述显示装置为同一装置，即所述检测装置可以为所述显示装置上为实现检测功能而设置的检测部分，为所述显示装置的一部分。换句话说，本公开的一些实施例提供的像素充电补偿的检测方法，可以是通过所述显示装置之外额外设置的第三方检测装置来执行，也可以通过所述显示装置来执行。
举例来讲，请同时参阅图2，图2为图1的方法中在显示区域上划分补偿区域的示意图。显示面板10包括位于衬底基板11上的多条扫描线12及多条数据线13，每条扫描线12沿第一方向延伸，多条扫描线12平行设置且沿第二方向排列。每条数据线13沿第二方向延伸，多条数据线13平行设置且沿第一方向排列。在一些实施例中，所述第一方向为水平方向，所述第二方向为竖直方向。在另一些实施例中，所述第一方向还可以为竖直方向，所述第二方向还可以为水平方向。
所述扫描线12在所述衬底基板11上的正投影与所述数据线13在所述衬底基板11上的正投影彼此交叉(例如彼此垂直)并且对应地在所述显示面板10的显示区域14中形成像素区域15。
在图2中，在所述显示区域14中划分补偿区域16时，可以是按照多个扫描线12的排列方向，也就是在竖直方向上，将所述显示区域14划分出至少两个补偿区域16，并且使得每个补偿区域16包括至少一条扫描线12，从而使得每个补偿区域16中具有与至少一条扫描线12连接的多个像素。在图2中是以每个补偿区域16包括两条扫描线12为例进行说明的。
步骤102、在显示面板显示预设的检测画面时检测每一补偿区域中的一个或多个目标像素中每个目标像素在预设充电时间下的第一亮度。
该步骤中，当所述检测装置在所述显示面板的显示区域中划分出所述至少两个补偿区域之后，所述检测装置可以控制所述显示装置的显示面板实现所述显示面板的显示功能，从而在所述显示面板上显示预设的检测画面。在显示所述检测画面时，检测装置可以对每一补偿区域中的一个或多个目标像素中每个目标像素的亮度进行检测，以便检测在显示所述检测画面时，每个目标像素在预设充电时间下的第一亮度。
其中，所述检测画面可以是预设的，并且可以是在显示时较容易凸显出对比度的画面，如具有不同黑白区域或者易产生不同对比度的画面。例如，检测画面是重载画面，即要求数据线13对每一行要做一次充放电的变化。
在检测画面的一个示例中，检测画面的每一行的亮度与相邻的另一行的亮度是反转的，例如一行的亮度是中间灰阶或其他对充电率敏感的灰阶，相邻的另一行的亮度是最暗的灰阶L0。
在检测画面的另一个示例中，检测画面是亮点和暗点间隔的画面，例如在水平方向上是亮点和暗点间隔的，在竖直方向上也是亮点和暗点间隔的(例如呈国际象棋棋盘状)。类似地，亮点的亮度是中间灰阶或其他对充电率敏感的灰阶，相邻的暗点的亮度是最暗的灰阶L0。
其中，所述一个或多个目标像素可以是在每一个补偿区域中为了方便检测而设置的具有代表性的像素，比如可以是位于补偿区域的中间位置的像素，或者是所述补偿区域中充电时间介于最长预设充电时间与最短预设充电时间中间的像素等。
在每个补偿区域中，可以具有一个或多个目标像素。每个补偿区域中的目标像素个数可以根据检测需要来进行设定，并不进行限定。如果同一补偿区域中具有两个或者两个以上的目标像素，那么所述两个或者两个以上的目标像素可以是连接在同一条扫描线上的不同位置，也可以是连接在不同的扫描线上的像素，而不同补偿区域中的目标像素，可以是连接在同一数据线上的像素，也可以是连接在不同数据线上的像素。
步骤103、获取该目标像素的第一亮度与预设亮度之间的差值。
该步骤中，在获取到该目标像素的第一亮度之后，所述检测装置可以将所述第一亮度与预设亮度进行对比，来获取该目标像素的第一亮度与预设亮度之间的差值。
其中，第一亮度与所述预设亮度之间的差值可以存在正数和负数，在实际检测中，可以取差值的绝对值，使得所述差值保持是正数，以便于后续的计算。
步骤104、基于所述差值，计算对所述目标像素进行充电的补偿时间。
步骤105、将所述补偿时间设定为对每个补偿区域中的像素进行充电的补偿时间。
在步骤104和105中，当所述检测装置获取到所述差值之后，所述检测装置可以根据充电亮度与充电时长之间的对应关系，来计算与每个所述差值对应的充电时间，从而得到对该目标像素进行充电的补偿时间，并且将该补偿时间设置为对该目标像素所在的补偿区域中的像素进行充电的补偿时间。该充电亮度与充电时长的对应关系可以是预先根据实验或者其他方式设定的。
其中，对每个补偿区域中像素进行充电的补偿时间可以指对该补偿区域中的所有像素进行充电的补偿时间，从而可以使用所述补偿时间改善所述显示面板中不同补偿区域的充电时间，使得所述显示面板整体的亮度达到大体一致。
其中，若同一补偿区域中具有两个或两个以上的目标像素，而得到两个或两个以上补偿时间的话，可以对该两个或两个以上的补偿时间取平均值，并且将该平均值设置为对该补偿区域的像素的进行充电的补偿时间。
本公开的一些实施例提供的像素充电补偿的检测方法，将显示区域按照扫描线的排列方向划分为至少两个补偿区域，其中，每一所述补偿区域中具有与至少一条扫描线连接的多个像素；在显示预设的检测画面时检测每一补偿区域中的目标像素在预设充电时间下的第一亮度；获取每个目标像素的第一亮度与预设亮度之间的差值；基于所述差值，计算对所述目标像素进行充电的补偿时间，并且将该补偿时间设置为对该补偿区域中的像素进行充电的补偿时间。通过将显示面板的显示区域划分至少两个补偿区域，并检测每个补偿区域中目标像素的第一亮度，根据第一亮度与预设亮度之间的差值，计算并且确定对目标像素所在补偿区域中的像素进行充电的补偿时间，这样，在使用该补偿时间对补偿区域中的像素的充电时间进行补偿后，可以使各个像素的充电时间大致相同，降低由于分辨率、像素密度和画面刷新率的提高，以及信号线的延迟导致的不同位置上的像素的充电时间差异，保证不同位置像素的充电时间均一性及充电时间充足，从而使得显示面板的显示区域上不同位置的亮度均匀。
参见图3，图3是本公开提供的像素充电补偿的检测方法的另一流程图。如图3所示，该检测方法包括以下步骤301-306。
步骤301、将显示面板的显示区域按照扫描线的排列方向划分为至少两个补偿区域，其中，每一所述补偿区域中具有与至少一条扫描线连接的多个像素。
步骤302、在该显示面板显示预设的检测画面时检测每一补偿区域中一个或多个目标像素中每个目标像素在预设充电时间下的第一亮度。
步骤303、获取该目标像素的第一亮度与预设亮度之间的差值。
步骤304、基于所述差值，计算对该目标像素进行充电的补偿时间。
其中，步骤301至步骤304的具体实现的描述可以参考步骤101至步骤104。
步骤305、使用所述预设充电时间及所述补偿时间，计算该目标像素的目标充电时间。
该步骤中，当所述检测装置通过所述差值计算得到对该目标像素进行充电的补偿时间之后，所述检测装置可以根据该目标像素的补偿时间，使用该目标像素的预设充电时间以及该目标像素对应的补偿时间，通过计算得到该目标像素进行充电的目标充电时间。
其中，所述目标充电时间，可以指每个补偿区域中的目标像素在利用经过所述补偿时间对预设充电时间进行补偿后，实际上对该目标像素进行充电时需要花费的充电时间。
步骤306、确定该目标像素对应的所述目标充电时间为对该目标像素所在的补偿区域中所有像素进行充电的充电时间。
该步骤中，当所述检测装置通过计算得到目标像素的目标充电时间后，所述检测装置可以对该目标像素的目标充电时间进行确定，确定该目标像素对应的所述目标充电时间为对该目标像素所在补偿区域中所有像素进行充电的总充电时间。
这样，通过检测以及计算，可以得到在经过补偿后对每个补偿区域中像素进行充电的总的充电时间，这样在所述显示面板后续使用时，可以直接调用每个补偿区域对应的目标充电时间，来一次性对补偿区域中的像素进行充电。
可选地，在步骤305以后并且在步骤306以前，所述方法还包括：计算所述一个或多个目标像素的目标充电时间的平均值，并且步骤306可以进一步包括确定所述平均值为对所述一个或多个目标像素所在的补偿区域中所有像素进行充电的充电时间。
可选的，步骤302包括：在显示预设的检测画面时，确认每一补偿区域中的一个或多个关键位置；并且检测所述一个或多个关键位置中每个关键位置上的目标像素在预设充电时间下的第一亮度。
该步骤中，当所述检测装置将所述显示面板的显示区域划分出至少两个补偿区域之后，所述检测装置可以控制在所述显示面板上显示预设的检测画面，并在显示所述检测画面时，检测每一补偿区域中的一个或多个关键点，并确定每一关键点的关键位置，从而检测所述关键位置上的目标像素在预设充电时间下的第一亮度。
其中，每一补偿区域中的关键点可以是在显示所述补偿画面时具有代表性的点，比如对比度比较明显的点，或者处于补偿区域中间位置的点等等。在补偿区域较少的情况下，可以选择沿数据线13方向的多个关键位置，来标定充电情况的分布，进而确定如何调整充电时间。例如，关键位置可以是补偿区域的输入端、中心和最远端，也可以是补偿区域的两端以及中间多个等间隔分布的位置。
其中，在预设充电时间下的第一亮度，可以是指在显示所述检测画面时且目标像素完成充电时的第一亮度。
可选的，所述使用所述预设充电时间及所述补偿时间，计算该目标像素的目标充电时间的步骤，包括：若所述第一亮度大于所述预设亮度，则该目标像素的目标充电时间为该目标像素的预设充电时间减去该目标像素的补偿时间；以及若所述第一亮度小于所述预设亮度，则该目标像素的目标充电时间为该目标像素的预设充电时间加上该目标像素的补偿时间。
该步骤中，在所述检测装置通过所述差值计算得到该目标像素的补偿时间之后，如果所述检测装置通过比对，得出所述第一亮度大于所述预设亮度，那么所述检测装置可以确定该目标像素的目标充电时间为该目标像素的预设充电时间减去该目标像素的补偿时间，如果所述检测装置通过比对，得出所述第一亮度小于所述预设亮度，那么所述检测装置可以确定该目标像素的目标充电时间为该目标像素的预设充电时间加上该目标像素的补偿时间。
可选的，补偿前所有补偿区域中像素充电的总时间与补偿后所有补偿区域中像素充电的总时间之间的差值小于预设门限。
其中，为了保证所述显示面板的画面刷新率等参数以及显示画面的一致性，所述显示面板在补偿前及补偿后的充电时间需要保持一致。因此，在补偿前每条数据线上的所有像素的充电时间与补偿后每条数据线上的所有像素 的充电时间大致相等，即补偿前每条数据线上的所有像素的充电时间与补偿后每条数据线上的所有像素的充电时间之间的差值，小于预设门限，即可以使得补偿前所有补偿区域中像素充电的总时间与补偿后所有补偿区域中像素充电的总时间之间的差值小于预设门限。
本公开的一些实施例提供的像素充电补偿的检测方法，将显示区域按照扫描线的排列方向划分为至少两个补偿区域，其中，每一所述补偿区域中具有与至少一条扫描线连接的多个像素；在显示预设的检测画面时检测每一补偿区域中目标像素在预设充电时间下的第一亮度；获取每个目标像素的第一亮度与预设亮度之间的差值；基于所述差值，计算对该目标像素进行充电的补偿时间；使用所述预设充电时间及所述补偿时间，计算每个目标像素的目标充电时间；确定每一目标像素对应的所述目标充电时间为对该目标像素所在的补偿区域中所有像素进行充电的充电时间。通过将显示面板的显示区域划分至少两个补偿区域，并检测每个补偿区域中目标像素的第一亮度，根据第一亮度与预设亮度之间的差值，计算对该目标像素进行充电的补偿时间，并基于补偿时间及预设充电时间，通过计算可以得到经过补偿后对该目标像素进行充电的目标充电时间，这样，在使用检测的补偿时间对补偿区域中像素的充电时间进行补偿后，可以使各个像素的充电时间大致相同，降低由于分辨率、像素密度和画面刷新率的提高，以及信号线的延迟导致的不同位置上的像素的充电差异，保证不同位置像素的充电均一性及充电时间充足，从而使得显示面板的显示区域上不同位置的亮度均匀。
本公开的一些实施例还提供一种像素充电的补偿方法。参见图8，所述像素充电的补偿方法包括：步骤801，根据对显示区域的补偿区域中像素进行充电所对应的补偿时间，对各补偿区域中的像素进行充电补偿，其中，所述补偿时间根据上述图1至图2中的像素充电补偿的检测方法确定。
请参阅图4至图7，图4为本公开提供的像素充电补偿的检测装置的结构图，图5为本公开提供的像素充电补偿的检测装置的另一结构图，图6为图4中所示的检测模块的结构图，图7为图5中所示的第二检测模块的结构图。这里的像素充电补偿的检测装置可以实现本公开上面的像素充电补偿的检测方法。
如图4至图7所示，所述检测装置400包括：划分模块410，用于将显示面板的显示区域按照多个扫描线的排列方向划分为至少两个补偿区域，其中，每一所述补偿区域中具有与至少一条扫描线连接的多个像素；检测模块420，用于在该显示面板显示预设的检测画面时检测每一补偿区域中一个或多个目标像素中每个目标像素在预设充电时间下的第一亮度；获取模块430，用于获取该目标像素的第一亮度与预设亮度之间的差值；以及第一计算模块440，用于基于所述差值，计算对该目标像素进行充电的补偿时间。
