背景技术
有机发光二极管(Organic Light-Emitting Diode，OLED)显示器具有高对比度、广视角、低功耗等优点，但OLED器件老化后，存在亮度降低、色点漂移的现象，出现该现象的主要原因是薄膜晶体管(Thin Film Transistor，TFT)阈值电压漂移及OLED器件发光效率衰减，显示亮度降幅与OLED器件的老化时间成正相关，如果各子像素的OLED器件老化程度不同，可能造成残影或显示器亮度不均匀现象。
目前常见的OLED补偿技术可分为光学补偿和电学补偿，其中，光学补偿可改善TFT电性能、OLED器件发光效率等引发的显示亮度不均匀现象，但光学补偿是在出厂前完成的，对使用过程中因OLED器件老化造成的显示亮度不均匀现象不适用；电学补偿对TFT的阈值电压漂移造成的显示亮度不均匀现象有改善作用，但不适用于OLED器件的发光效率衰减造成的显示亮度不均匀现象。因此，上述两种补偿技术，对出厂后因OLED器件的发光效率衰减引起的显示亮度不均匀现象均不能改善。

请参阅图1B，图1B是本申请实施例提供的一种亮度补偿方法的实施例流程示意图。如图1B所示，本实施例中所描述的亮度补偿方法，包括以下步骤：
101、驱动装置接收由移动终端发送的至少一张补偿表。
本申请的一些实施例中，驱动装置可与移动终端通过无线的方式进行连接，并接收移动终端发送的至少一张补偿表。
其中，每一张补偿表中包含针对显示器显示的显示画面中的至少一个像素点的原始灰阶值，和与原始灰阶值对应的亮度补偿值。
102、获取由显示器显示的第一显示画面中目标像素点的目标灰阶值，根据所述至少一张补偿表确定所述目标像素点对应的修正值，根据所述修正值对所述目标像素点进行亮度补偿，并驱动所述显示器显示亮度补偿后的所述第一显示画面。
本申请的实施例中，显示器显示的第一画面内容中包含N个像素点，N为大于1的整数，目标像素点可为N个像素点中的任意一个像素点。
其中，第一显示画面可包括N个任意灰阶值的像素点构成的显示画面，例如，第一显示画面可以是纯色画面，也可以是彩色画面。
其中，目标灰阶值为目标像素点在第一显示画面中应该显示的灰阶值，由于有机发光二极管的老化引起的发光效率衰减，需要对目标像素点进行亮度补偿。
可选地，针对第一显示画面中的目标像素点的目标灰阶值进行亮度补偿，可根据补偿表中目标像素点对应的原始灰阶值和亮度补偿值计算目标像素点的修正值。
可选地，上述步骤102中，根据所述至少一张补偿表确定所述目标像素点对应的修正值，可包括如下步骤：
21、若在所述至少一张补偿表中，仅有第一补偿表中包含所述目标像素点对应的第一原始灰阶值gs1和第一亮度补偿值ΔX 1，则从所述第一补偿表中获取所述第一原始灰阶值gs1和所述第一亮度补偿值ΔX 1，并根据如下公式计算所述目标像素点对应的修正值L：
L＝gray0+ΔX 1-gs1
其中，gray0为所述显示器显示的第一显示画面中目标像素点的目标灰阶值；
22、若在所述至少一张补偿表中，存在第二补偿表中包含所述目标像素点对应的第二原始灰阶值gs2和第二亮度补偿值ΔX 2，以及，第三补偿表中包含所述目标像素点对应的第三原始灰阶值gs3和第三亮度补偿值ΔX 3，则从所述第二补偿表中获取所述目标像素点对应的第二原始灰阶值gs2和第二亮度补偿值ΔX 2，从所述第三补偿表中获取所述目标像素点对应的第三原始灰阶值gs3和第三亮度补偿值ΔX 3，并根据如下公式计算所述目标像素点对应的修正值L：
L＝ΔX 2+(gray0-gs2)*(ΔX 3-ΔX 2)/(gs3-gs2)
其中，gray0为所述显示器显示的第一显示画面中目标像素点的目标灰阶值。
本申请实施例中，至少存在一张补偿表包含目标像素点对应的原始灰阶值和亮度补偿值。
可选地，驱动装置可确定显示器显示的第一显示画面中的目标像素点的位置，该位置例如可为行、列数，根据该位置查找到第一补偿表中第m行、第n列的第一原始灰阶值和第一亮度补偿值，然后执行步骤21中的计算，m和n为正整数。
例如，显示器在第一显示画面中的目标像素点要显示的目标灰阶值为90，驱动装置中存储了原始灰阶值为64的第一补偿表，目标像素点在第一原始灰阶值为64时，对应的亮度补偿值是70，则修正值为90+70-64＝96。
可选地，驱动装置确定了目标像素点的位置后，根据该位置查找到第二补偿表中对应的目标像素点的第二原始灰阶值gs2和第二亮度补偿值ΔX 2，以及，第三补偿表中对应的目标像素点的第三原始灰阶值gs3和第三亮度补偿值ΔX 3，判断第二原始灰阶值gs2、第三原始灰阶值gs3与目标灰阶值gray0的大小，若gs2<gray0<gs3，则执行步骤22中的计算。
例如，显示器在第一显示画面中的目标像素点要显示的目标灰阶值为128，驱动装置中存储了原始灰阶值为80的第二补偿表，目标像素点在第二原始灰阶值为80时，对应的亮度补偿值是87，驱动装置中还存储了原始灰阶值为160的第三补偿表，目标像素点在第三原始灰阶值为160时，对应的亮度补偿值是164，则修正值为164+(128-160)*(87-164)/(80-160)≈133。
可以看出，通过本申请实施例中，驱动装置接收移动终端发送的至少一张补偿表，获取由显示器显示的第一显示画面中目标像素点的目标灰阶值，根据上述至少一张补偿表确定与目标像素点对应的修正值，若仅有第一补偿表中包含所述目标像素点对应的第一原始灰阶值和第一亮度补偿值，则根据第一补偿表中的第一原始灰阶值和第一亮度补偿值计算目标像素点的修正值，若针对目标像素点的补偿表的数量大于1时，可根据多张补偿表中的多个原始灰阶值和多个亮度补偿值计算修正值，使计算结果更加可靠，根据该修正值对第一显示画面中的目标像素点进行亮度补偿，并驱动显示器显示亮度补偿后的第一显示画面，可消除出厂后因OLED器件的发光效率衰减引起的第一显示画面中显示亮度不均匀现象。
与上述一致地，请参阅图2，图2为本申请实施例提供的另一种亮度补偿方法的实施例流程示意图。本实施例中所描述的亮度补偿方法，可包括以下步骤：
201、移动终端建立至少一张补偿表。
本申请的实施例中，用户可通过移动终端建立至少一张补偿表。
其中，一张补偿表中包含的所有像素点对应同一个原始灰阶值，例如，一张补偿表中包含T个像素点的原始灰阶值为64，由于各个像素点对应的有机发光二极管的老化情况不同，各个像素点分别对应的亮度补偿值不同，T为大于或等于1的整数。
可选地，上述步骤201中，移动终端建立至少一张补偿表，可包括如下步骤：
A1、所述移动终端接收用户触发的控制指令，向所述驱动装置发送显示指令，所述显示指令用于指示所述驱动装置驱动所述显示器显示第二显示画面，所述第二显示画面为纯色画面；
A2、接收由用户触发的拍摄指令，针对所述显示器显示的所述第二显示画面拍摄目标图像，根据所述目标图像生成补偿表i，所述补偿表i为所述至少一张补偿表中的任一补偿表。
本申请的实施例中，控制指令用于指示移动终端启动亮度补偿应用，并显示亮度补偿的应用界面，以及向驱动装置发送显示指令，控制指令可包含一组连续的指令。
其中，显示指令用于指示驱动装置驱动显示器显示第二显示画面，用户可通过移动终端设置第二显示画面为纯色画面以及该纯色画面对应的原始灰阶值。
当显示器显示第二显示画面后，用户可通过移动终端拍摄针对显示器显示的第二显示画面的目标图像，拍摄目标图像时，移动终端可生成与显示器显示第二显示画面的尺寸比例相同的取景框，用户将取景框与第二显示画面的边缘对齐后再进行拍摄，如此，可拍摄到与第二显示画面中的尺寸比例相同的目标图像。
可选地，上述步骤A2中，移动终端根据目标图像生成补偿表i，可包括如下步骤：
B1、所述移动终端显示所述目标图像；
B2、接收由用户触发的图像放大指令，将所述目标图像进行放大处理；
B3、接收用户发送的补偿设置信息，根据所述补偿设置信息生成所述补偿表i，所述补偿设置信息包括：所述目标图像中目标区域的位置信息和针对所述目标区域的调整值。
本申请的实施例中，显示器显示的第二显示画面和目标图像的分辨率不同，例如，第二显示画面的分辨率可为1920*1080，目标图像的分辨率可为3200*1800，由于目标图像的尺寸比例与第二显示画面的尺寸比例相同，第二显示画面中的N个像素点中，每一像素点对应于目标图像中的一个区域，该区域可包括至少一个像素点，例如，显示器显示的第二显示画面中，第100行、第100列的像素点可对应目标图像中第166至167行、第166至167列的像素点。
可选地，用户可设定针对目标区域增加某一调整值，也可设定针对目标区域减少某一调整值。
其中，将目标图像进行放大处理，有利于用户在目标图像中选取目标区域。
其中，用户可在移动终端上针对放大的目标图像，选取亮度不均匀的目标区域，并针对该目标区域设置一个调整值，移动终端可确定该目标区域的位置信息。
可选地，上述步骤B3中，移动终端根据补偿设置信息生成补偿表i，可包括如下步骤：
C1、若目标区域对应于所述显示器中的所述目标像素点，则根据如下公式计算所述显示器显示的所述第二显示画面中所述目标像素点的亮度补偿值ΔX i：
ΔX i＝gs*(f+Δgray)/f
其中，gs为所述显示器显示的所述第二显示画面中所述目标像素点的原始灰阶值，f为所述目标图像中对应于所述目标像素点的区域的第一平均灰阶值，Δgray为针对所述目标区域的调整值；
C2、若所述目标区域包括K个子区域，所述K个子区域分别对应于所述显示器显示的第二显示画面中的K个像素点，所述K个像素点包括目标像素点，K为大于1的整数，则根据如下公式计算所述显示器显示的所述第二显示画面中所述目标像素点的亮度补偿值ΔX i：
Figure PCTCN2018075443-appb-000001
d i＝|f i-mean|
其中，gs为所述显示器显示的所述第二显示画面中所述目标像素点的原始灰阶值，f为所述目标图像中对应于所述目标像素点的区域的第一平均灰阶值，f i为所述K个子区域中任一子区域的平均灰阶值，Δgray为针对所述目标区域的调整值，mean为所述目标图像中所有像素点的第二平均灰阶值，针对所述K个子区域，d i为所述K个子区域中任一子区域的平均灰阶值与所述第二平均灰阶值的差值绝对值，d 1为所述目标图像中目标像素点对应的区域的第一平均灰阶值与所述第二平均灰阶值的差值绝对值，d max为K个子区域对应的K个差值绝对值中的最大值；
C3、根据所述亮度补偿值生成所述补偿表i。
本申请的实施例中，用户选取的目标区域可对应显示器显示的第二显示画面中的至少一个像素点。
可选地，可获取目标图像中对应于目标像素点的区域的第一平均灰阶值f，若目标区域对应于显示器显示的第二显示画面中的目标像素点，则第一平均灰阶值f为目标区域的平均灰阶值，根据步骤C1中的公式计算目标像素点的亮度补偿值ΔX i。
例如，用户选取目标图像中的第166至167行、第166至167列，并设定调整值为增加10，移动终端确定目标图像中该目标区域的平均灰阶值90，根据该目标区域的位置信息可确定显示器显示的第二显示画面中的第100行、第100列的目标像素点，假定显示器显示的第二显示画面中目标像素点的原始灰阶值为64，则目标像素点的亮度补偿值为64*(90+10)/90≈71。
可选地，若目标区域对应于显示器显示的第二显示画面中的K个像素点，即目标区域包括K个子区域，K个子区域中的每一区域对应于所述显示器显示的第二显示画面中的一个像素点，针对任一子区域，移动终端可确定该子区域的位置信息，根据该位置信息确定对应于第二显示画面中的目标像素点，该目标像素点为K个像素点中的任意一个。
其中，针对用户在目标图像上选取的的目标区域，移动终端可获取上述K个子区域中的每一区域的平均灰阶值，并获取目标图像中所有像素点的第二平均灰阶值，然后根据步骤C2中的公式计算目标像素点的亮度补偿值ΔX i。
举例说明，用户选取目标图像中第158至167行、第158至167列的目标区域，并设置调整值为增加10，移动终端确定目标图像中所有像素点的第二平均灰阶值为100，在目标区域中，第166至167行、166至167列的第一子区域的平均灰阶值为90，与第二平均灰阶值的差值绝对值最大，根据第一该子区域的位置信息可确定显示器显示的第二显示画面中的第100行、第100列的第一像素点，第158至159行、第158至159列的第二子区域的平均灰阶值为95，与第二平均灰阶值的差值绝对值偏小，根据该第二子区域的位置信息可确定显示器显示的第二显示画面中的第95行、第95列的第二像素点，假定显示器显示的第二显示画面中的像素点的原始灰阶值为64，则第100行、第100列的第一像素点对应的亮度补偿值为64*(90+10*10/10)90≈71，第95行、第95列的第二像素点对应的亮度补偿值为64*(95+10*5/10)/95≈67。
其中，移动终端计算出针对目标像素点的亮度补偿值后，可生成补偿表i，补偿表i中包含显示器显示的第二显示画面各个像素点在同一原始灰阶值下的亮度补偿值。
202、将所述至少一张补偿表发送至驱动装置，由所述驱动装置获取由显示器显示的第一显示画面中目标像素点的目标灰阶值，根据所述至少一张补偿表确定所述目标像素点对应的修正值，根据所述修正值对所述目标像素点进行亮度补偿，并在所述显示器上显示亮度补偿后的所述第一显示画面。
可选地，用户生成补偿表i后，可将补偿表i发送至驱动装置，驱动装置根据补偿表i对第二显示画面进行亮度补偿，并驱动显示器显示亮度补偿后的第二显示画面，用户可根据补偿后的第二显示画面判断补偿效果是否满意，若用户满意，则通过移动终端向驱动装置发送确认指令，驱动装置根据该确认 指令保存补偿表i；若用户不满意，则可重复执行上述步骤A2的操作，得到新的补偿表，并将该新的补偿表发送至驱动装置，驱动装置根据新的补偿表对显示器的显示画面进行亮度补偿，直到用户认为补偿效果满意。
可以看出，通过本申请实施例中，移动终端建立至少一张补偿表，其中，用户通过移动终端拍摄目标图像，用户在目标图像中选取目标区域，若该目标区域对应显示器显示的显示画面中的目标像素点，则通过目标图像中目标像素点对应的区域的第一平均灰阶值计算亮度补偿值，若该目标区域对应显示器显示的显示画面中的多个像素点，则根据目标区域中对应于多个像素点中每一像素点的子区域的平均灰阶值计算多个像素点中每一像素点的亮度补偿值，如此，可使亮度补偿值的计算结果更加可靠，移动终端根据上述亮度补偿值生成至少一张补偿表中的任意一张，并将该任意一张补偿表发送至驱动装置，由所述驱动装置获取由显示器显示的第一显示画面中目标像素点的目标灰阶值，根据所述至少一张补偿表确定所述目标像素点对应的修正值，根据所述修正值对所述目标像素点进行亮度补偿，并驱动显示器显示亮度补偿后的第一显示画面，可消除出厂后因OLED器件的发光效率衰减引起的第一显示画面中显示亮度不均匀现象。
