为了便于理解，下面先对本公开实施例的技术背景进行介绍。
现有技术中，如前文所述，显示屏可以整屏显示、或者仅控制部分显示区域显示，而另一部分区域则处于休眠状态，这种情况下，由于显示屏中各显示区域的显示时长不同，使得显示区域对应的发光器件的老化程度也不同，进而使得显示屏在整屏显示时出现显示不均匀、显示效果差的技术问题。
鉴于此，本公开的发明人提供了一种显示装置的亮度调节的方案，在该方案中，当显示屏出现显示不均匀的情况时，可以通过调节显示屏中各子显示屏的驱动电流，以使得显示屏中各显示区域的显示亮度之差维持在预定亮度范围内，从而可以减小甚至消除不同显示区域的显示不均匀，增强显示屏的显示效果。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。

电源芯片(Power IC)11，电源芯片11与第一子屏131以及第二子屏132电连接；
控制器10，控制器10与电源芯片11、第一子屏131、第二子屏132、计时器12均电连接，被配置为获取第一总显示时长和第二子显示时长，并在确定第一总显示时长与第二总显示时长的差值时长满足预设条件时，控制电源芯片11向第一子屏131、第二子屏132提供不同的供电电流，以使第一子屏131和第二子屏132同平面显示时亮度一致。具体的，控制器10具体被配置为确定第一总显示时长大于第二总显示时长时，控制电源芯片11向第一子屏131输出的供电电流大于向第二子屏132输出的供电电流。
其中，显示屏13可以是利用有机电自发光二极管(Organic Light-Emitting Diode，OLED)技术制成的显示屏，即显示屏13可以是OLED显示屏，由于OLED显示屏具备自发光有机电激发光二极管，不需背光源，且可制作成挠曲式面板，挠曲式面板具有可折叠弯曲性，也就是说，可以根据将OLED显示屏可以制作成可折叠的显示屏。当然，显示屏13还可以是其它能够进行显示的屏，本公开实施例不做限制。在本公开实施例中，可以将显示屏13可以划分为两个或者多个显示区域，如图1中所示的将显示屏13划分为了第一子 屏131和第二子屏132这两个显示区域，第一子屏131和第二子屏132直接具有折叠轴(如图中虚线所示)，控制器10分别连接电源芯片11、以及计时器12以及显示屏13；电源芯片11至少包括两个输出端，该至少两个输出端分别显示屏13所包括的多个显示区域一一对应，例如，其中的一个输出端与第一子屏131连接，被配置为第一子屏131提供驱动电流，另一个输出端与第二子屏132连接，被配置为第二子屏132提供驱动电流；计时器12可以分别为显示屏13的第一子屏131和第二子屏132的显示时长计时。
在本公开实施例中，控制器10中可以集成有控制芯片，控制器10可以控制显示屏13整屏显示，也可以控制显示屏13中的部分显示区域进行显示，例如，分别控制图1所示的第一子屏131或第二子屏132进行显示，或者控制第一子屏131和第二子屏132同时进行显示。电源芯片11被配置为显示屏13提供驱动电流以使得显示屏13发光进行显示，控制器10可以根据显示屏13需要显示的区域，控制电源芯片11为需要显示的区域供给驱动电流；计时器12被配置为对显示屏13所划分的各个显示区域的显示时长进行计时，例如，可以将计时器12为第一子屏131进行计时的时长的称作第一总显示时长，以及将计时器12为第二子屏132进行计时的时长称作第二总显示时长。
具体的，请参见图2和图3，显示屏13可以是如图2所示的不可进行折叠的屏幕，也可以是如图3所示的可折叠屏。当显示屏13为图2所示的不可折叠的屏幕时，可以将显示屏13化分为图2中所示的第一子屏131和第二子屏132，需要说明的是，图2中所示的第一子屏131和第二子屏132的划分仅仅是示意性的，在具体实施过程中，第一子屏131和第二子屏132还可以是其它形式和比例的划分，本公开实施例不做限制。从而，控制器10可以控制电源芯片11仅为第一子屏131供给驱动电流，驱动第一子屏131进行显示，或者仅为第二子屏132供给驱动电流，驱动第二显示区进行显示，也可以控制电源芯片11同时为第一子屏131和第二子屏132同时供给电流，以使得显示屏13整屏显示。也就是说，当显示屏13划分为多个显示区域后，控制器10可以控制电源芯片11单独为各个显示区域供给驱动电流，从而可以控制显 示屏13局部亮屏显示或整屏进行显示，以满足用户差异化的显示需求。进而，控制器10也可以控制计时器12分别对第一子屏131和第二子屏132进行计时。
当显示屏13为可折叠显示屏13时，可以以图3所示的折叠线L为分界线，将可折叠显示屏13分为第一子屏和第二子屏这两个子屏，可以将第一子屏对应的显示区域称为第一子屏131，将第二子屏对应的显示区域称为第二子屏132，其中，两个子屏所占显示屏13的比例可以是任意比例，如图3中所示的是1:1的比例。控制器10可以控制电源芯片11同时为显示屏13的第一子屏131和第二子屏132供给驱动电流，以使显示屏13的第一子屏和第二子屏共同进行显示，即双屏显示；或者也可以控制电源芯片11分别为显示屏13中的第一子屏131或第二子屏132供给驱动电流，以控制第一子屏131或第二子屏132单独进行显示，即单屏显示。进而，控制器10也可以控制计时器12分别对第一子屏131和第二子屏132进行计时。
当然，显示屏13也可以分为多于两个子屏的更多个子屏，例如三个子屏或者四个子屏，而多个子屏的显示控制方式与两个子屏的显示控制方式的原理是类似的，本公开实施例以两个子屏进行举例说明，对于更多子屏的情况就不做具体描述了。
在具体实施时，计时器12包括的计时器的数量可以与显示屏13中划分的显示区域的数量相同，也可以不相同，当计时器的数量与显示区域的数量相同时，每个显示区域连接一个计时器，通过一一对应关系，一个计时器可以对对应的一个显示区域的显示时长进行计时。例如，前文所述的将显示屏13分为第一子屏131和第二子屏132，则第一子屏131与第一计时器连接，第二子屏132与第二计时器连接，通过第一计时器计和第二计时器，分别计时第一子屏131的显示时长和第二子屏132的显示时长。
基于上述介绍的显示装置，本公开实施例提供了一种显示装置的亮度调节方法，如图4所示，该方法的具体流程描述如下。
步骤401：获取显示屏13的第一子屏131的第一总显示时长，以及获取 显示屏13的第二子屏132的第二总显示时长，第一子屏131与第二子屏132具有折叠轴L，第一子屏131，以及第二子屏132可以绕折叠轴进行折叠。具体的，第一总显示时长可以理解为第一子屏由出厂至当前显示时刻的总显示时长，第二总时长可以理解为第二子屏由出厂至当前显示时刻的总显示时长，即，关于步骤S401，获取显示屏13的第一子屏131的第一总显示时长，以及获取显示屏13的第二子屏132的第二总显示时长，可以具体包括：获取第一子屏131由出厂至当前显示时刻的第一总显示时长，以及获取第二子屏132由出厂至当前显示时刻的第二总显示时长。
具体的，为了方便说明，结合图1所示的显示装置，以如图3所示，显示屏13划分为第一子屏131和第二子屏132这两个子屏为例进行具体说明。如前文所述，可以通过计时器来分别统计显示屏13中第一子屏131的第一总显示时长和第二子屏132的第二总显示时长，从而控制器可以从计时器中获取第一子屏131的第一总显示时长和第二子屏132的第二总显示时长。
例如，可折叠移动终端中的显示屏13为可折叠屏，当用户在使用该可折叠移动终端时，可以将该可折叠移动终端展开使用，即通过整个显示屏13进行显示，也可以将该可折叠动终端折叠使用，即通过显示屏13中部分显示区域进行显示。因此，当可折叠移动终端折叠使用的时间较多时，容易出现因可折叠屏中经常使用的那部分显示区域因使用时间较长，而使得经常使用的部分显示区域对应的发光器件老化程度增大，发光效率降低，进而造成可折叠屏中经常使用的部分显示区域和不常使用的部分显示区域出现显示不均匀的情况。
步骤402：确定第一总显示时长与第二总显示时长的差值时长满足预设条件时，控制与第一子屏和第二子屏电连接的电源芯片向第一子屏131、第二子屏132提供不同的供电电流，以使第一子屏131和第二子屏132同平面显示时亮度一致。具体的，对于有机发光显示面板，其供电电流的大小，与电源电压和数据电压的差值(Vdd-Vdata)有关，即，可以通过增大电源电压或减小数据电源来实现对供电电流的降低，而若采用增大电源电压来实现对供电 电流的调整，折叠显示屏需要两个单独的控制器芯片来实现调整，不利于折叠显示屏的制作成本，进而，在具体实施时，可以通过对数据电压的调整来实现对供电电流的调整，即，对于步骤S420中的，控制与第一子屏和第二子屏电连接的电源芯片向第一子屏、第二子屏提供不同的供电电流，包括：控制电源芯片向第一子屏的数据线、第二子屏的数据线提供不同的供电电流。
在本公开实施例中，由于显示屏13中的发光器件会随着工作时间的增加而产生老化，工作时间越长老化程度越大，发光器件的发光效率也越来越低，进而当不同显示区域的老化程度不相同，且老化到一定程度后，可能会出现不同显示区域之间显示不均匀、显示效果差的问题。因此，可以通过显示屏13中第一子屏131的第一总显示时长和第二子屏132的第二总显示时长，来确定第一子屏131和第二子屏132当前的显示亮度，从而确定第一子屏131和第二子屏132是否出现了显示不均匀、显示效果差的问题。
具体的，关于步骤S420、确定第一总显示时长与第二总显示时长的差值时长满足预设条件时，控制与第一子屏和第二子屏电连接的电源芯片向第一子屏、第二子屏提供不同的供电电流，包括：步骤S4201、确定第一总显示时长大于第二总显示时长时，控制电源芯片向第一子屏提供的供电电流大于向第二子屏提供的供电电流。通常而言，显示屏的显示时长越长，亮度越低，本公开实施例中，在第一子屏131的第一总显示时长大于第二子屏132的第二总显示时长时，向第一子屏131提供更高的供电电流，可以实现使第一子屏131和第二子屏132的亮度一致。
在具体实施时，关于在执行步骤S4201时，即，在控制电源芯片向第一子屏提供的供电电流大于向第二子屏提供的供电电流时，方法还包括：控制电源芯片向第二子屏的供电电流保持不变。本公开实施例中，对于通过调大显示时长较长的子显示屏的供电电流以使不同子屏的显示亮度一致，对于显示时长较短的子显示屏，可以不对其亮度进行调整，即，保持显示时长较短的子屏以原提供的供电电流工作，而对于显示时长较长的子屏，可以调高其供电电流，进而实现其二者的亮度一致。
在具体实施时，在执行步骤S4201时，本公开实施例提供的亮度调节方法，还包括：确定第二总显示时长大于第一时长时，控制电源芯片向第二子屏的供电电流增大。本公开实施例中，在通过调大显示时长较长的子显示屏的供电电流以使不同子屏的显示亮度一致，对于两个子屏中总显示时长较短的一者，若其总显示时长也超过一定的范围(也即第一时长，第一时长可以为第二子屏亮度低于预设亮度时，第二子屏由出厂至当前显示时刻的总显示时长)时，可以认为两个屏均使用了较长的时间，即，两个子屏的发光亮度均低于正常的显示亮度，在该种情况下，为了提高用户的使用体验，让人眼具有较好的观看效果，可以对总显示时长较短的子屏的显示亮度也进行提高，当然，即便总显示时长较短的子屏的供电电流也提高，但其仍小于总显示时长更长的显示子屏的供电电流，以维持二者亮度的一致。
在具体实施时，对于步骤S4201中的，控制电源芯片向第一子屏提供的供电电流大于向第二子屏提供的供电电流，包括：控制电源芯片向第一子屏、第二子屏提供的供电电流的差值电流与差值时长成正比。本公开实施例中，提供给第一子屏和第二子屏的供电电流的差值电流，与第一子屏和第二子屏显示的差值时长成正比，即，两个子屏的差值时长越大，差值电流越大，进而以满足使两个子屏的显示亮度一致。
为了更清楚地理解本公共实施例提供的显示装置的亮度调节方法，以下以图5为例，对本公开实施提供的亮度调节方法进行举例说明如下：
步骤401：获取显示屏13的第一子屏131的第一总显示时长，以及获取显示屏13的第二子屏的第二总显示时长。具体可以通过计时器来对第一子屏131的第一总显示时长，对第二子屏132的第二总显示时长进行计时，之后，将第一总显示时长和第二总显示时长发送给控制器，进而，控制器可以获取到该第一总显示时长和第二总显示时长。
步骤402：判断第一总显示时长与第二总显示时长是否满足预设条件。
进一步地，可以通过判断第一子屏131的第一总显示时长和第二子屏132的第二总显示时长的差值时长是否满足预设条件，来判断显示屏13是否出现 显示不均匀的情况，其中，预设条件为第一子屏131和第二子屏132开始出现显示不均匀情况的临界条件，为了便于理解，以下列举几种情况进行举例说明。
第一种情况：若第一总显示时长与第二总显示时长不相等，即，差值时长不为零，则确定满足预设条件。在本公开实施例中，由于随着发光时间增加显示屏13中发光器件的发光效率会衰减，使用时间越长，显示屏13中的发光器件老化程度越大，发光效率也衰减的更多，所以，当第一子屏131和第二子屏132的使用时间不同时，第一子屏131和第二子屏132对应的发光器件的发光效率也不相同、显示亮度也自然不同，容易出现显示不均匀的情况，进而需要对第一子屏131和/或第二子屏132的显示亮度进行调节。
第二种情况：若第一总显示时长与第二总显示时长之间的差值时长大于或等于第一预设差值，则确定满足预设条件。
在具体实施时，显示效果主要是显示屏13呈现的画面带给用户的视觉感受的效果，若显示屏13中各显示区域之间的显示亮度差距不大，带给用户的视觉差异也不会太大，人眼无法察觉到各显示区域之间的显示变化，那么自然也没有调节显示屏13亮度的必要，所以，本公开实施例中，可以根据人眼视觉的灵敏度确定一个用户能够发现显示屏13出现显示不均匀情况的最小亮度差值，进而确定产生该亮度差值的最小时间。
也就是说，可以将在用户开始察觉到显示屏13发生显示不均匀时，第一子屏131的第一总显示时长和第二子屏132的第二总显示时长的差值时长作为第一预设差值，若最终确定出的第一子屏131的第一总显示时长与第二子屏132的第二总显示时长之间的差值时长小于该第一预设差值时，则可以表明此时显示屏13的显示不均匀，处于用户眼睛无法察觉的范围内，不需要调节各显示区域的显示亮度。若最终确定出的第一总显示时长与第二总显示时长之间的差值大于等于该预设时间差值范围，则可以表明此时显示屏13的显示不均匀，可以被用户眼睛可以察觉到，需要调节各显示区域的显示亮度。所以，可以避免频繁的调节显示屏13中各显示区域的显示亮度，造成电能浪 费，从而在提高显示效果的同时，还可以节约电能。
第三种情况，若第一总显示时长与第二总显示时长中的最大时长大于预定时长，且第一总显示时长与第二总显示时长之间的差值时长大于或等于第二预设差值，则确定满足预设条件。
在具体实施时，由于显示屏13的总显示时间越长，其老化速率越快，例如，刚出厂的显示屏13和使用一段时间后的显示屏13的老化速率并不相同，那么显示屏13在总显示时间较短的时候，显示屏13的显示亮度变化也较小，所以，可能在第一子屏131和第二子屏132的显示时长之差较大时，用户才能观察到显示不均匀的情况，而在使用一段时间后，由于显示屏13的老化速率增大了，所以，可能在第一子屏131和第二子屏132的显示时长之差较小时，用户就可以察觉到显示屏13出现了显示不均匀的情况。
因此，可以根据显示屏13中发光器件的老化速度的变化趋势，设置一个预定时长，以该预定时长为界，在达到预定时长之前，显示屏13中发光器件的老化速率变化较小，超过该预定时长，显示屏13的发光器件的老化速率变化增长。进而，可以将第一子屏131的第一总显示时长和第二子屏132的第二总显示时长中的最大时长，当最大时长大于预定时长，且第一总显示时长与第二总显示时长之间的差值大于或等于第二预设差值时，则确定需要进行亮度调节，此时进行显示亮度调节的时间间隔，小于第二种情况中进行显示亮度调节的时间间隔。
例如，假设预定时长为10000小时，那么，10000小时内显示屏13中发光器件的老化速率小于超过10000小时后显示屏13中发光器件的老化速率，所以，在10000小时内，可以将第一预设差值设置为800小时，当第一总显示时长与第二总显示时长之间的差值设置大于或等于800小时后，才确定满足预设条件，需要进行亮度调节。当第一总显示时长和第二总显示时长中的最大时长超过10000小时后，可以将第二预设差值设置为400小时，那么，第一总显示时长与第二总显示时长的差值大于或等于400时，则确定满足预设条件，需要进行亮度调节。由此可知，在10000小时内，显示屏13亮度调 节的频率小于超过10000小时后显示屏13亮度调节的频率，所以，可以根据显示屏13的使用时间来确定显示屏13亮度调节的频率，减小对显示屏13中各显示区域亮度调节的频率，以提高显示屏13的显示效果。
步骤403：判断所述第一子屏131和第二子屏132是否均处于显示状态。
在本公开实施例中，确定是否需要调节显示屏13中各显示区域的当前显示亮度，可以在显示屏13中各显示区域均处于显示状态时进行，也可以是在显示屏13中各显示区域处于息屏状态下进行，还可以是在部分区域处于显示状态，另一部分区域处于息屏状态时进行判断。当显示屏13处于息屏状态，或者部分区域处于显示状态、部分区域处于息屏状态时，不需要调节显示屏13中各显示区域的亮度，所以，在调节显示屏13中各显示区域的亮度之前可以先确定该显示屏13中的所有显示区域是否均处于显示状态，即第一子屏131和第二子屏132是否均处于显示状态，若第一子屏131和第二子屏132处于均显示状态，则执行步骤404。
步骤404：将第一子屏131的驱动电流调节至第一目标驱动电流，和/或将第二子屏132的驱动电流调节至第二目标驱动电流，以使第一子屏131的显示亮度与第二子屏132的显示亮度的差值处于预定差值范围内，该预设差值范围可以理解为是人眼观看时的亮度一致的范围。
在本公开实施例中，显示屏13中发光器件的驱动电流越大，其发光亮度越亮，也就是说，显示屏13的驱动电流越大，则显示屏13的显示亮度越亮。当显示屏13中的发光器件发生老化时，其显示亮度会降低，所以可以通过增大显示屏13的驱动电流的方式来增大显示屏13的显示亮度。进而，当显示屏13中各显示区域的显示亮度不相同，使得用户可以察觉到显示屏13各显示区域之间显示不均匀时，可以通过调节各显示区域的驱动电流的方式来使显示屏13显示均匀，提高显示屏13的显示效果。
在具体实施时，可以确定第一子屏131的第一目标驱动电流，通过将第一子屏131的驱动电流调节至第一目标驱动电流，使得第一子屏131的显示亮度和第二子屏132的显示亮度的差值处于预定差值范围内，也就是说，可 以仅通过调节第一子屏131的驱动电流，来使得第一子屏131和第二子屏132显示均匀；也可以确定第二子屏132的第二目标驱动电流，通过将第二子屏132的驱动电流调节至第二目标显示驱动电流，使得第二子屏132的显示亮度与第一子屏131的显示量的差值处于预定范围内，也就是说，可以仅通过调节第二子屏132的驱动电流，来使得第一子屏131和第二子屏132显示均匀；还可以同时确定第一子屏131的第一目标驱动电流，以及第二子屏132的第二目标驱动电流，通过将第一子屏131的驱动电流调节至第一目标驱动电流，将第二子屏132的驱动电流调节至第二目标显示驱动电流，以使第一子屏131的显示亮度和第二子屏132的显示亮度的差值处于预定差值范围内，也就是说，可以通过同时调节第一子屏131的驱动电流和第二子屏132的驱动电流，从而减小或者消除第一子屏131和第二子屏132显示不均匀的情况，以提高整个显示屏出现显示的均匀性，进而提高显示效果。
在本公开实施例中，将第一子屏131的驱动电流调节至第一目标驱动电流，和/或将第二子屏132的驱动电流调节至第二目标驱动电流后，第一目标驱动电流驱动第一子屏131进行显示时的显示亮度，与第二目标驱动电流驱动第一子屏131进行显示时的显示亮度可以相等，也就是说，进行亮度调节后，第一子屏131和第二子屏132显示亮度相同，不存在亮度差，所以消除了第一子屏131和第二子屏132之间显示不均匀的情况，提高了显示屏13的显示效果。需要说明的是当仅调节第一子屏或第二子屏132中的显示亮度时，未进行亮度调节的那一显示区域对应的驱动电流不发生改变。
进一步地，如前文所述，当显示屏13的各显示区域的显示亮度差值较小时，用户的视觉灵敏对不高，此时用户并不会察觉到各显示区域的显示亮度不同，因此，对显示区域中的各显示区域进行亮度调节后，第一子屏131的显示亮度和第二子屏132的显示亮度可以不相同，满足处于用户察觉不到出现显示不均时显示亮度的预设差值范围内即可。
例如，当同时对第一子屏131和第二子屏132显示亮度进行调节时，第一目标驱动电流驱动第一子屏131进行显示时的显示亮度，与第二目标驱动 电流驱动第一子屏131进行显示时的显示亮度也可以不相等，只要第一子屏131的显示亮度和第二子屏132的显示亮度的差值处于预定差值范围内，该预定差值范围为不会引起用户视觉差异时，第一子屏131与第二子屏132的最大亮度差值。也就是说，第一子屏131与第二子屏132的最大亮度差值处于在该预定差值范围内时，用户眼中的显示屏13是处于显示均匀状态的。
需要说明的是，由于对显示屏13中第一子屏131和/或第二子屏132进行亮度调节后，可以使得第一子屏131和第二子屏132显示均匀，所以，此时第一子屏131和第二子屏132的显示亮度的差值，应当比进行显示亮度调节前，第一子屏131和第二子屏132的显示亮度的差值小。
作为一种可选的实施方式，本公开实施例中，当根据第一子屏131的第一总显示时长和第二子屏132的第二总显示时长，确定出显示屏13的第一子屏131和第二子屏132出现显示不均，需要对显示屏13中各显示区域进行亮度调节时，可以先根据第一子屏131的第一总显示时长，以及第二子屏132的第二总显示时长，确定出第一子屏131和第二子屏132中显示亮度较高的显示区域当前的驱动电流，并根据该显示亮度较高的显示区域的总显示时长和当前的驱动电流，从预先设置的显示亮度、显示时长及驱动电流之间的对应关系中确定出该显示亮度较高的显示区域当前的显示亮度，进而，以该显示亮度较高的显示区域的当前显示亮度为准，从预先设置的显示亮度、显示时长及驱动电流之间的对应关系中，确定第一子屏131和第二子屏132中显示亮度较低的显示区域的目标驱动电流，以使显示亮度较低区域的驱动电流调节至该目标驱动电流调节后，使得该显示亮度较低的显示区域对应的显示亮度与较高区域的显示亮度的差值处于预定范围内，以减小甚至消除第一子屏131和第二子屏132显示不均匀的情况，以提高整个显示屏出现显示的均匀性，从而提高显示效果。
也就是说，可以通过增大第一子屏131和第二子屏132中显示亮度较低的显示区域的显示亮度，使得第一子屏131和第二子屏132的显示亮度之差处于预定差值范围内。
具体的，当第一子屏131的第一总显示时长小于所第二子屏132的第二总显示时长时，则通过调节以使第一目标驱动电流小于第二目标驱动电流。例如，假设，进行显示亮度调节前，第一子屏131对应的亮度为100，第一总显示时长为10000小时，驱动电流为3A，第二子屏132的显示亮度为60，第二总显示时长为20000小时，驱动电流为3A，出现了显示不均匀的情况，其中第一子屏131的显示亮度高于第二子屏132的显示亮度。所以，在进行显示亮度调节时，可以以第一子屏131的显示亮度100为准，从预先设置的显示亮度、显示时长及驱动电流之间的对应关系中，确定出将第二子屏132的显示亮度调节100时，对应的第二目标驱动电流为3.1A，进而将第二子屏132当前的驱动电流由3A调节至3.1A。
作为一种可选的实施方式，在进行显示亮度调节时，也可以通过降低第一子屏131和第二子屏132中显示亮度较高区域的显示亮度，以使第一子屏131和第二子屏132的显示亮度处于预定差值范围内，从而使得第一子屏131和第二子屏132显示均匀，如前文所述，显示亮度越高，驱动电流越大，所以，若要降低显示亮度较高的显示区域的显示亮度，可以通过降低该显示区域驱动电流的方式进行，从而在减小或者消除第一子屏131和第二子屏132显示不均匀的情况，以提高整个显示屏出现显示的均匀性，提高显示效果的同时，还可以节约电能。
具体的，当第一子屏131的第一总显示时长大于所第二子屏132的第二总显示时长时，则通过调节以使第一目标驱动电流大于第二目标驱动电流。例如，假设，进行显示亮度调节前，第一子屏131对应的亮度为110，第一总显示时长为8000小时，驱动电流为2A，第二子屏132的显示亮度为90，第二总显示时长为18000小时，驱动电流为2A，出现了显示不均匀的情况，其中，第一子屏131的显示亮度高于第二子屏132的显示亮度。所以，在进行显示亮度调节时，可以以第二子屏132显示亮度90为准，从预先设置的显示亮度、显示时长及驱动电流之间的对应关系中，确定出将第一子屏131的显示亮度调节90时，对应的第二目标驱动电流为1.9A，进而将第一子屏131当 前的驱动电流由2A调节至1.9A。
作为一种可选的实施方式，在进行显示亮度调节时，考虑显示亮度过高和过低都会增加用户眼睛的负担，所以在进行亮度调节时，可以同时调节第一子屏131和第二子屏132的显示亮度，即确定一个处于第一子屏131当前亮度和第二子屏132的当前显示亮度之间，不影响用户查看显示内容的显示亮度，同时将第一子屏131的显示亮度和第二子屏132的显示亮度调节至不影响用户查看显示内容的显示亮度，所以，在减小或者消除第一子屏131和第二子屏132显示不均匀情况，以提高整个显示屏出现显示的均匀性，提高显示效果的同时，还可以降低用户用眼负担。
例如，假设，进行显示亮度调节前，第一子屏131对应的亮度为100，第一总显示时长为10000小时，驱动电流为3A，第二子屏132的显示亮度为60，第二总显示时长为20000小时，驱动电流为3A，出现了显示不均匀的情况，其中，第一子屏131的显示亮度高于第二子屏132的显示亮度。所以，在进行显示亮度调节时，可以先在60-100的亮度范围内确定一个显示度值，如80，进而，以显示亮度80为准，从预先设置的显示亮度、显示时长及驱动电流之间的对应关系中，分别确定出将第一子屏131的显示亮度调节至80时，对应的第一目标驱动电流为2.95A，将第二子屏132的显示亮度调节至80时，对应的第二目标驱动电流为3.05A，进而将第一子屏131当前的驱动电流由3A调节至2.95A，将第二子屏132当前的驱动电流由3A调节至3.05A，以减小或者消除第一子屏131和第二子屏132显示不均匀的情况，以提高整个显示屏出现显示的均匀性。
作为一种可选的实施方式，为了使得显示屏13的第一子屏131和第二子屏132进行亮度调节后的显示亮度，能够更利于用户使用，避免出现调节后的最终显示亮度偏低，或调节后的最终显示亮度偏高，影响显示屏13显示效果，增加用户用眼负担，本公开实施例中，可以根据显示屏13当前所在的环境光强、用户使用习惯预先设置一个预定亮度范围，进而根据该预定亮度范围第一子屏131和第二子屏132的最终显示亮度，从而调节第一子屏131的 驱动电流和/或第二子屏132的第二驱动电流，以使第一子屏131和第二子屏132显示均匀，从而提高显示屏13的显示效果。
