具体实施方式
下面结合附图和实施例对本申请作详细说明。
相关技术中的全面屏显示面板随着使用时间的增长第一显示区和第二显示区存在较大的亮度差异，影响显示效果。出现这种问题的原因在于：随着显示面板使用时间的增长，第一显示区和第二显示区的老化程度不同，导致随着使用时间的增长第一显示区和第二显示区之间存在亮度差异，且不同的显示面板第一显示区和第二显示区的亮度差异不同，导致一些补偿方法无法对第一显示区和第二显示区之间的亮度差异进行较好的补偿。
本申请实施例提供了一种显示面板的补偿方法，其应用于显示面板，图1是本申请实施例提供的一种显示面板的示意图，参考图1，显示面板包括第一显示区11和第二显示区12，第二显示区12的透光率与第一显示区11的透光率不同。
其中，第一显示区11可以为显示面板的主显示区，第二显示区12为显示面板的透明显示区，第一显示区11和第二显示区12均可以显示画面。可选的，第二显示区12的透光率可以大于第一显示区11的透光率，第二显示区12的非发光侧可以对应设置有光学传感器，光学传感器包括摄像头等光学器件。
图2是本申请实施例提供的一种显示面板的补偿方法的流程图，参考图2，补偿方法包括：
S110、以第一显示区的第一显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二显示灰阶。
其中，用户在使用过程中若对第二显示区的显示效果不满意可以手动调节第二显示区的显示亮度和/或色度。在显示面板中为第二显示区设置亮度调节条和色度调节条，用户通过拖动第二显示区的亮度调节条和色度调节条对第二显示区进行显示调节，直至对第二显示区的显示效果满意，或第二显示区与第一显示区的显示效果一致，第二显示灰阶即用户停止调节时第二显示区的实际显示灰阶。
此外，用户可以在显示面板的第一显示区显示某一个第一显示灰阶时对第二显示区的显示效果进行显示调节，也可以对第一显示区分别显示多个不同的第一显示灰阶时分别对第二显示区的显示效果进行显示调节。示例性的，用户可以以第一显示区显示某一高灰阶(如245灰阶)时为基准显示灰阶对第二显示区的显示效果进行调节，也可以第一显示区显示某一低灰阶(如80灰阶)时为基准显示灰阶对第二显示区的显示效果进行调节。例如，用户可以在第一显示区显示第一个第一显示灰阶时对第二显示区进行显示调节，得到一组第一显示灰阶和第二显示灰阶，然后在第一显示区显示第二个第一显示灰阶时对第二显示区进行显示调节，得到第二个第一显示灰阶对应第二显示灰阶，依次类推，完成对多个不同第一显示灰阶的显示调节。
S120、根据第一显示灰阶和第二显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的差异系数。
示例性的，使用时长为显示面板出厂后从第一次开始点亮后的累积点亮时长。当前使用时长为当前时刻显示面板的累积点亮时长。差异系数反映第一显示区和第二显示区当前时刻的显示差异。当用户对第一显示区在分别显示多个不同第一显示灰阶时分别对第二显示区的显示效果进行显示调节时，调节完毕时得到多个不同第一显示灰阶分别对应的第二显示灰阶，可以根据多个不同第一显示灰阶和多个不同第一显示灰阶分别对应的第二显示灰阶得到多个差异系 数。
S130、根据差异系数和预先存储的显示补偿曲线确定第二显示区的补偿起始时长，其中，显示补偿曲线为第二显示区的使用时长和第二显示区与第一显示区的差异系数之间关系的变化曲线。
S140、从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿。
示例性的，图3是本申请实施例提供的一种显示补偿曲线的示意图，参考图3，显示补偿曲线反映随使用时长的增长第二显示区与第一显示区的差异系数的变化。可以对与显示面板同类型的其他显示面板进行测试，得到显示补偿曲线，还可以对与显示面板同类型的其他显示面板的历史显示数据进行统计，并根据统计后的所述历史显示数据，得到显示补偿曲线。
根据差异系数和预先存储的显示补偿曲线确定第二显示区的补偿起始时长，可以在显示补偿曲线上查找与差异系数对应的使用时长，将该使用时长确定为补偿起始时长。
从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，可以根据补偿起始时长对第二显示区的使用时长进行修正，得到实际等效使用时长，根据实际等效使用时长在显示补偿曲线上查找对应的差异系数，根据该差异系数对第二显示区进行补偿。示例性的，可以计算显示面板的使用时长(当前时刻之后任一补偿时刻的显示面板的累积使用时长)与当前时刻对应的当前使用时长的第一差值，将第一差值与补偿起始时长求和得到实际等效使用时长，在显示补偿曲线上确定实际等效使用时长对应的差异系数，根据实际等效使用时长对应的差异系数和第二显示区的待显示灰阶确定第二显示区的实际显示灰阶，第二显示区的实际显示灰阶与待显示灰阶的差值即第二显示区的补偿值。或者，确定补偿起始时长与当前使用时长的第二差值，将显示面板的使用时长与第二差值求和得到实际等效使用时长，在显示补偿曲线上确定实际等效使用时长对应的差异系数，根据实际等效补偿时长对应的差 异系数和第二显示区的待显示灰阶确定第二显示区的实际显示灰阶。
从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，还可以从当前时刻将显示面板的使用时长重置为零，重新开始对显示面板的使用时长进行计时，将补偿起始时长对应位置确定为起始补偿零点，每次补偿时根据重新计时的使用时长在显示补偿曲线上查找对应的差异系数，根据该差异系数对第二显示区进行补偿。
显示补偿曲线可以在显示面板制作时预先存储在显示面板中，显示面板的驱动芯片根据显示补偿曲线对第二显示区进行补偿。由于随使用时间的增长不同的显示面板的第二显示区的老化程度不同，因此随着使用时长的增长显示补偿曲线无法对第二显示区进行较好的补偿，导致显示面板的第一显示区和第二显示区存在较大的显示差异。
本实施例根据当前时刻第二显示区与第一显示区的差异系数以及显示补偿曲线确定补偿起始时长，从当前时刻开始根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，由于补偿起始时长根据当前使用时长对应的差异系数确定，在补偿时可以采用补偿起始时长对显示面板的使用时长进行修正，使得补偿时根据显示补偿曲线确定的差异系数更符合第二显示区与第一显示区的实际差异，可以更好的对第二显示区进行补偿，减小第一显示区和第二显示区之间的亮度差异，提升显示效果。
需要说明的是，显示面板中可以预先存储一条显示补偿曲线，当用户仅以第一显示区的某一第一显示灰阶为基准显示灰阶对第二显示区的显示效果进行显示调节，得到一组第一显示灰阶和第二显示灰阶，从而得到一个差异系数，可以根据该差异系数和显示补偿曲线确定一个补偿起始时长。当用户以第一显示区的多个不同第一显示灰阶为基准显示灰阶对第二显示区的显示效果进行显示调节时，根据不同的基准显示灰阶得到多个差异系数，根据该多个差异系数和显示补偿曲线确定多个补偿起始时长。在显示面板进行显示时，根据显示面板的待显示灰阶选择对应的补偿起始时长，根据对应的补偿起始时长和显示补 偿曲线对第二显示区进行补偿。
可选的，根据第一显示灰阶和第二显示灰阶确定当前时刻第一显示区和第二显示区的差异系数，包括：差异系数＝(第二显示灰阶-第一显示灰阶)/第一显示灰阶。
示例性的，第一显示灰阶和第二显示灰阶可以均为白画面灰阶，即红色子像素、绿色子像素和蓝色子像素的综合显示灰阶。在亮度调节和色度调节均完成后，可以根据色度公式对红色子像素、绿色子像素和蓝色子像素的显示灰阶进行折算得到第二显示灰阶。相应的显示补偿曲线可以为白灰阶的补偿曲线。
第一显示灰阶和第二显示灰阶也可以均为单色子像素的显示灰阶，例如第一显示灰阶和第二显示灰阶可以均为红色子像素的显示灰阶，第一显示灰阶和第二显示灰阶也可以均为绿色子像素的显示灰阶，第一显示灰阶和第二显示灰阶也可以均为蓝色子像素的显示灰阶。相应的，显示补偿曲线可以为单色补偿曲线。
可选的，图4是本申请实施例提供的又一种显示面板的补偿方法的流程图，参考图4，显示面板的补偿方法包括：
S101、获取用户的亮度调节指令，根据亮度调节指令调节第二显示区的显示亮度。
示例性的，显示面板中可以设置有亮度调节条，用户拖动亮度调节条时，显示面板获取到亮度调节指令，根据拖动量对第二显示区的显示亮度进行调节。此外，显示面板中还可以设置有亮度调节框，用户可以输入调节的灰阶值或亮度值，输入完毕后显示面板获取到亮度调节指令，根据该灰阶值或亮度值对第二显示区的显示亮度进行调节。
S102、获取用户的色度调节指令，根据色度调节指令调节第二显示区的显示色度。
示例性的，显示面板中可以设置有色度调节条，用户拖动色度调节条时，显示面板获取到色度调节指令，根据拖动量对第二显示区的显示色度进行调节。 此外，显示面板中还可以设置有色度调节框，用户可以输入调节的色度值或灰阶值，输入完毕后显示面板获取到色度调节指令，根据该灰阶值或色度值对第二显示区的显示色度进行调节。需要说明的是，本实施例仅示例性的示出了几种调节色度和亮度的形式，并非对本申请的限定，在其他实施方式中还可以有其他调节方式。此外，本实施例中用户可以根据需要选择只调节亮度、只调节色度或者同时调节色度和亮度，当用户只调节亮度时，显示面板只能获取到亮度调节指令，当用户只调节色度时，显示面板只能获取到色度调节指令，当用户同时调节色度和亮度时，显示面板即能获取到色度调节指令，又能获取到亮度调节指令。
S103、接收到用户的确认指令或用户不再输入亮度调节指令和色度调节指令时，确定显示调节完毕。
示例性的，用户对第一显示区和第二显示区的显示效果满意后可以停止亮度调节和色度调节。显示面板可以设置确认按钮，用户调节完毕后点击确认按钮，显示面板接收到确认指令，显示调节完毕，或者在设定时间内用户不再进行亮度调节和色度调节，确认显示调节完毕。
S110、以第一显示区的第一显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二显示灰阶。

S140、从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿。
本实施例用户可以根据需要随时对第一显示区和第二显示区进行显示调节，即可以随时重新确定补偿起始时长，可以随时对显示面板的显示效果进行调节， 操作过程简单，提升用户体验。
可选的，从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，包括：
根据补偿起始时长和显示面板的使用时长确定使用时长对应的第二显示区和第一显示区的实际差异系数；
根据实际差异系数和第二显示区的待显示灰阶确定第二显示区的实际显示灰阶；
根据实际显示灰阶对第二显示区进行补偿。
示例性的，待显示灰阶为第二显示区即将显示的灰阶，实际显示灰阶为第二显示区补偿后的显示灰阶。可以根据补偿起始时长和显示面板的使用时长确定实际等效使用时长，并确定实际等效使用时长对应的第二显示区和第一显示区的实际差异系数。在一些实施例中，可以根据补偿起始时长对第二显示区的使用时长进行修正，得到实际等效使用时长，根据实际等效使用时长在显示补偿曲线上查找对应的差异系数确定实际差异系数，根据实际差异系数和第二显示区的待显示灰阶计算第二显示区的实际显示灰阶。
可选的，根据实际显示灰阶对第二显示区进行补偿，包括：根据实际显示灰阶调节第二显示区的数据驱动信号或者发光控制信号。
示例性的，数据驱动信号即通过数据线写入到子像素的驱动电压信号，可以直接根据实际显示灰阶调整第二显示区待补偿子像素的数据驱动信号，使第二显示区的待补偿子像素的数据驱动信号等于实际显示灰阶的数据驱动信号，从而使待补偿子像素显示实际显示灰阶对应的亮度，减小第二显示区与第一显示区的显示差异。
此外，发光控制信号即通过发光控制线输入到子像素的信号，发光控制信号用于控制子像素的发光时长，通过调整发光控制信号的占空比，可以调整待补偿子像素每一帧画面的发光时长，从而调整待补偿子像素的显示亮度，使待 补偿子像素显示实际显示灰阶对应的亮度，减小第二显示区与第一显示区的显示差异。
可选的，第一显示灰阶包括n个第一子显示灰阶，n为大于或等于2的正整数，且n个第一子显示灰阶相互之间的差值均大于设定阈值；以第一显示区的第一显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二显示灰阶，包括：分别以第一显示区的每一个第一子显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二子显示灰阶。
根据第一显示灰阶和第二显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的差异系数，包括：对每一个第一子显示灰阶，根据第一子显示灰阶和该第一子显示灰阶对应的第二子显示灰阶确定显示面板当前使用时长下该第一子显示灰阶对应的第二显示区与第一显示区的第一子差异系数。
根据差异系数和预先存储的第二显示区的显示补偿曲线确定第二显示区的补偿起始时长，包括：对每一个第一子显示灰阶，根据第一子显示灰阶对应的第一子差异系数和预先存储的第二显示区的显示补偿曲线确定该第一子显示灰阶对应的第二显示区的第一子补偿起始时长。
从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，包括：从当前时刻起根据待显示灰阶、显示面板的使用时长、待显示灰阶对应的第一子补偿起始时长和第二显示区的显示补偿曲线对第二显示区进行补偿。
示例性的，可以以第一显示区的第一个第一子显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第一个第二子显示灰阶；以第一显示区的第二个第一子显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二个第二子显示灰阶；以此类推，直至以第一显示区的第n个第一子显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第n个第二子显示灰阶。
然后，根据第一个第一子显示灰阶和第一个第二子显示灰阶确定显示面板 当前使用时长下第二显示区与第一显示区的第一个第一子差异系数；根据第二个第一子显示灰阶和第二个第二子显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的第二个第一子差异系数；以此类推，直至根据第n个第一子显示灰阶和第n个第二子显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的第n个第一子差异系数。
分别根据第一个第一差异系数、第二个第一差异系数……以及第n个第一差异系数和预先存储的显示补偿曲线确定第二显示区的n个第一子补偿起始时长。
待显示灰阶对应的第一子补偿起始时长即与待显示灰阶最接近的第一子显示灰阶对应的第一子补偿起始时长。补偿时可以计算待显示灰阶与每一第一子显示灰阶的差值确定待显示灰阶最接近的第一子显示灰阶，从而确定其对应的第一子补偿起始时长。此外，也可设置每一第一子显示灰阶对应一灰阶范围，补偿时可以直接根据待显示灰阶所属的灰阶范围确定待显示灰阶对应的第一子显示灰阶，从而确定其对应的第一子补偿起始时长。确定待补偿显示灰阶对应的第一子补偿起始时长后，根据第一子补偿起始时长对显示面板的使用时长进行修正，得到实际等效使用时长，从而对第二显示区进行补偿。
由于不同的灰阶下，第一显示区和第二显示区之间显示差异不同，通过以第一显示区多个不同的第一子显示灰阶为基准显示灰阶对第二显示区进行显示调节得到至少两个不同的第一子差异系数，该至少两个不同的第一子差异系数分别反映第一显示区显示对应的第一子显示灰阶时，第二显示区和第一显示区的显示差异。
显示面板可以仅设置一条显示补偿曲线，通过每一个第一子差异系数和该显示补偿曲线分别得到与每一个第一子差异系数对应的第一子补偿起始时长。每一第一子补偿起始时长分别对其对应的第一子显示灰阶所在的灰阶范围进行补偿，由于每一第一子差异系数可以准确的反映其对应的第一子显示灰阶下第一显示区和第二显示区的显示差异，因此通过该第一子差异系数得到的第一子 补偿起始时长可以较好的反映当前使用时长时第二显示区的实际等效使用时长，根据第一子补偿起始时长和使用时长确定的实际等效使用时长和显示补偿曲线可以更好的对该第一子补偿起始时长对应第一子显示灰阶所在灰阶范围内第一显示区和第二显示区的显示差异进行补偿，从而在第二显示区显示不同的待显示灰阶时均可以进行较好的补偿，减小第一显示区和第二显示区的显示差异，提升显示效果。
可选的，第一显示灰阶包括n个第一子显示灰阶；以第一显示区的第一显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二显示灰阶，包括：分别以第一显示区的每一个第一子显示灰阶为基准显示灰阶，获取用户调节第二显示区后第二显示区的第二子显示灰阶；
根据第一显示灰阶和第二显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的差异系数，包括：对每一个第一子显示灰阶，根据第一子显示灰阶和该第一子显示灰阶对应的第二子显示灰阶确定显示面板当前使用时长下该第一子显示灰阶对应的第二显示区与第一显示区的第一子差异系数；
根据差异系数和预先存储的第二显示区的显示补偿曲线确定第二显示区的补偿起始时长，包括：显示面板包括m条不同的显示补偿曲线，一条显示补偿曲线对应至少一个第一子显示灰阶，m为小于或等于n的正整数；对每一个第一子显示灰阶，根据第一子显示灰阶对应的第一子差异系数和对应的显示补偿曲线确定该第一子显示灰阶对应的第二显示区的第二子补偿起始时长；
从当前时刻起根据显示面板的使用时长、补偿起始时长和显示补偿曲线对第二显示区进行补偿，包括：确定第二显示区的待显示灰阶对应的第二子补偿起始时长和待显示灰阶对应的显示补偿曲线；从当前时刻起根据显示面板的使用时长、待显示灰阶、待显示灰阶对应的第二子补偿起始时长和待显示灰阶对应的显示补偿曲线对第二显示区进行补偿。
示例性的，可以设置每一第一子显示灰阶均对应一条显示补偿曲线，显示补偿曲线对该第一子显示灰阶的灰阶范围进行补偿。由于不同灰阶范围第二显 示区和第一显示区的老化差异不同，通过对每一第一子显示灰阶设置一个对应的显示补偿曲线，即对每一灰阶范围设置一对应的显示补偿曲线，可以更好的对第二显示区进行补偿。通过采用每一第一子显示灰阶对应的第一子差异系数和该第一子显示灰阶对应的显示补偿曲线得到对应的第二子补偿起始时长，根据对应的第二子补偿起始时长和显示补偿曲线可以对该第一子显示灰阶对应的灰阶范围内的各灰阶进行更好的补偿，从而在第二显示区显示不同的待显示灰阶时均可以进行更好的补偿，减小第一显示区和第二显示区之间的差异，提升显示效果。
示例性的，在补偿时可以先确定第二显示区的待显示灰阶(即将显示的灰阶)所在的灰阶范围，根据该灰阶范围确定该灰阶范围对应的显示补偿曲线和第二子补偿起始时长。根据该灰阶范围对应的第二子补偿起始时长、使用时长和该灰阶范围对应的显示补偿曲线确定第二显示区和第一显示区的实际差异系数，根据实际差异系数和待显示灰阶可以得到第二显示区补偿后的实际显示灰阶。
此外，由于不同的灰阶下，第一显示区和第二显示区之间老化差异不同，且灰阶差值越大，第一显示区和第二显示区之间的老化差异越不同。示例性的，第一显示区和第二显示区显示第一灰阶时的差异系数为a，显示第二灰阶时的差异系数为b，第一灰阶和第二灰阶之间的差值越大，a和b之间的差值越大。本实施例通过设置n个第一子显示灰阶相互之间的差值大于设定阈值，通过以该n个第一子显示灰阶为基准显示灰阶对第二显示区进行显示调节得到的n个第二子补偿起始时长和显示补偿曲线可以分别对该n个第一子显示灰阶对应的灰阶范围进行补偿，可以对不同的灰阶范围进行有针对性的补偿，更好的补偿第二显示区和第一显示区之间的差异，提升显示效果。
可选的，显示面板包括至少三种不同发光颜色的子像素，每一显示补偿曲线包括至少三种不同的子显示补偿曲线，一种发光颜色的子像素对应一种子显示补偿曲线，不同发光颜色的子像素对应不同的子显示补偿曲线；根据第一显 示灰阶和第二显示灰阶确定显示面板当前使用时长下第二显示区与第一显示区的差异系数，包括：对每一发光颜色的子像素，根据第一显示灰阶和第二显示灰阶确定显示面板当前使用时长下该发光颜色的子像素对应的第二显示区与第一显示区的第二子差异系数。
其中，第一显示灰阶和第二显示灰阶可以为白色灰阶，此时根据第一显示灰阶和第二显示灰阶以及色度公式得到第一显示区和第二显示区的每一发光颜色子像素的灰阶，根据第一显示区和第二显示区同颜色子像素的显示灰阶得到该颜色的第二子差异系数。第一显示灰阶和第二显示灰阶也可以为单色显示灰阶，此时可以直接根据第一显示灰阶和第二显示灰阶得到该颜色子像素对的第一显示区和第二显示区之间的第二子差异系数。
根据差异系数和预先存储的第二显示区的显示补偿曲线确定第二显示区的补偿起始时长，包括：对每一发光颜色的子像素，根据该颜色的子像素对应的第二子差异系数和该颜色的子像素对应的子显示补偿曲线确定该颜色的子像素对应的第三子补偿起始时长。

示例性的，显示面板可以包括红色发光子像素、绿色发光子像素和蓝色发光子像素，显示补偿曲线可以包括红色子补偿曲线、绿色子补偿曲线和蓝色子补偿曲线。
本实施例通过对每一发光颜色子像素存储对应的子显示补偿曲线，并根据该颜色的子像素对应的第二子差异系数和该颜色的子像素对应的子显示补偿曲线确定该颜色的子像素对应的第三子补偿起始时长，对每一发光颜色的子像素，从当前时刻起根据显示面板的使用时长、该颜色的子像素对应的第三子补偿起始时长和该颜色子像素对应的子显示补偿曲线对第二显示区的该颜色的子像素 进行补偿，可以对每一颜色的子像素进行有针对性的补偿，减小第一显示区和第二显示区的显示差异。
