此外，下面所描述的本申请不同实施例中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
本申请实施例提供的屏幕驱动方法可在任何合适类型的电子设备中执行，诸如智能手机、计算机、掌上电脑(Personal Digital Assistant，PDA)、平板电脑或智能手表等等。其中，电子设备可被构造成任何合适形状以满足不同业务场景。
本申请实施例提供的屏幕驱动装置作为软件功能模块/单元，可整合在处理器中，以执行本申请实施例提供的屏幕驱动方法。
本申请实施例提供一种显示面板。请参阅图1a，显示面板100包括：若干数据线101、若干扫描线102、芯片103、若干像素单元104及驱动电路105。
数据线101与扫描线102交叉设置。数据线101用于提供数据信号，扫描线102用于逐行扫描各个像素单元104，从中选通特定的像素单元104。当特定的像素单元被选通后，数据信号便可施加于该特定的像素单元。
芯片103作为时序控制逻辑的核心，其能够按照预设时序逻辑扫描各个像素单元并传输数据信号。
像素单元104可以为任何合适的像素结构，诸如有机发光二极管(Organic Light-Emitting Diode，OLED)、液晶单元等等。
驱动电路105包括数据线驱动电路和扫描线驱动电路，数据线驱动电路分别与数据线101和芯片103连接，扫描线驱动电路分别与扫描线102和芯片103连接，芯片103可分别通过数据线驱动电路和扫描线驱动电路向数据线101和扫描线102传输信号，以驱动显示面板100中的各个像素104进行显示。
在一些实施例中，显示面板100支持任何合适位数的灰阶显示，诸如全灰阶为0-255灰阶或0至1023灰阶的等等。
显示面板100作为屏幕集成于手机上显示，其中，显示面板100可以为柔性显示面板，亦可以为刚性显示面板。柔性显示面板受折叠应用的影响，折叠后，一部分屏幕区域可显示画面，另一部分屏幕区域未可显示画面。刚性显示面板受使用次数或屏幕区域划分的影响，其可以出现亮度不均匀的不同屏幕区域。以柔性显示面板为例，请参阅图1b，显示面板100沿着折叠线106折叠，于是，显示面板100被划分为显示区107与非显示区108，位于显示区107中对应的全部像素单元被点亮，位于非显示区108中对应的全部像素单元被熄灭。
当显示面板100沿着折叠线106折叠了多次后，由于不同折叠区域的亮暗次数不同，OLED材料随着发光次数的增加，发光性能逐渐下降。因此，当需要展开显示时，先前不同折叠区域的显示亮度会存在差异的。请参阅图1c，用户总共对显示面板折叠80次，其中，在折叠后的历史点亮次数中，第一屏幕区域1c1被点亮的次数为30次，第二屏幕区域1c2被点亮的次数为50次。在展开显示时，第一屏幕区域1c1比较亮，第二屏幕区域1c2比较暗。出于不同角度地观察，在一些实施例中，第一屏幕区域1c1可被称为亮度异常区域，第二屏幕区域1c2可被称为亮度正常区域。在另一些实施例中，第一屏幕区域1c1可被称为亮度正常区域，第二屏幕区域1c2可被称为亮度异常区域。
在本申请实施例中，通过亮度调节，其能够将第一屏幕区域1c1与第二屏幕区域1c2的亮度调节一致，使得第一屏幕区域1c1与第二屏幕区域1c2之间的亮度分界线得以消失，使得各个屏幕区域的亮度均匀显示。
作为本申请实施例的一方面，本申请实施例提供一种屏幕显示方法。请参阅图2a，屏幕显示方法200包括：
S21、确定屏幕的亮度异常区域；
在本实施例中，屏幕使用柔性基板或刚性基板，柔性基板诸如包括薄玻璃、金属箔片或塑料基底等等具有柔性的材料，例如，塑料基底具有包括涂覆在基膜的两侧上的柔性结构，基膜包括诸如聚酰亚胺(PI)、聚碳酸酯(PC)、聚乙二醇对酞酸酯(PET)、聚醚砜(PES)、聚乙烯薄膜(PEN)、纤维增强塑料(FRP)等等树脂。刚性基板可以为，但不局限于玻璃基板、金属基板、或陶瓷基板。
在本实施例中，折叠时，以折叠线为分界线，屏幕被分为至少两个屏幕区域，其中，一个屏幕区域中各行像素单元按照第一方向被点亮，另一个屏幕区域中各行像素单元未被点亮。其中，该折叠线可在形成屏幕时已被构造及预设，亦可以由用户折叠屏幕而形成的。
在本实施例中，第一方向可由用户自定义，例如，以屏幕所在的平面建立坐标系XOY，第一方向可以为自X正半轴到X负半轴的方向，可以为自X负半轴到X正半轴的方向，可以为自Y正半轴到Y负半轴的方向，可以为自Y负半轴到Y正半轴的方向。
屏幕的亮度异常区域的产生因素可多种，例如，如前所述，屏幕经过多次折叠后，由于不同屏幕区域在历史点亮次数上存在不同，导致不同屏幕区域在展开显示时，存在亮度显示不均匀的现象，亦即，亮度过亮的屏幕区域可为亮度异常区域，或者，亮度过暗的屏幕区域可为亮度异常区域。
再例如，虽然各个屏幕区域的历史点亮次数相同，但是屏幕受制作工艺的影响，不同屏幕区域的亮度也会出现不均匀的情况，亦即，不同屏幕区域的亮度之间存在差异化，在此种情况下，亮度过亮的屏幕区域可为亮度异常区域，或者，亮度过暗的屏幕区域可为亮度异常区域。
S22、获取亮度异常区域被点亮的起始时间；
在本实施例中，由于驱动电路按照一定方向依序扫描各行像素单元，由此而点亮各行像素单元，因此，屏幕的不同屏幕区域被点亮的起 始时间是不同的，起始时间为每个屏幕区域中首先被点亮的首行像素单元的点亮时间。例如，屏幕排列有150行像素单元，在显示一帧画面下，每行像素单元的扫描时间为0.2ms，当屏幕不存在亮度异常区域时，该屏幕被点亮的起始时间为第一行像素单元的起始时间，亦即为第0ms。当屏幕存在亮度异常区域与亮度正常区域，其中，亮度正常区域为第1行至第50行的像素单元，亮度异常区域为第51行至第150行的像素单元，因此，亮度正常区域被点亮的起始时间为第0ms，亮度异常区域被点亮的起始时间为第10ms。
S23、根据起始时间，调节亮度异常区域的亮度。
在本实施例中，屏幕自亮度异常区域的起始时间开始，便开始调节亮度异常区域的亮度，举例而言，调节亮度异常区域的亮度与亮度正常区域的亮度相同，例如，将亮度过亮的屏幕区域的亮度调低，直至该屏幕区域与其它屏幕区域的亮度相一致，或者，将亮度过暗的屏幕区域的亮度调高，直至该屏幕区域与其它屏幕区域的亮度相一致。
再举例而言，调节亮度异常区域的亮度与亮度正常区域的亮度之间的差值落入预设阈值范围内。
在本实施例中，通过补偿亮度异常区域的亮度，从而提高显示效果以及画质品质。
在一些实施例中，确定屏幕的亮度异常区域的方式比较多，例如，通过获取在指定灰阶下屏幕对应的显示画面，通过图像分析算法分析该显示画面，从中确定屏幕的亮度异常区域。再例如，其还可以通过统计屏幕中各个屏幕区域对应的历史点亮时间以确定亮度异常区域。请参阅图2b，S21包括：
S211、获取屏幕中各个屏幕区域对应的历史点亮时间；
S212、选择满足预设条件的历史点亮时间对应的屏幕区域作为亮度异常区域。
在本实施例中，历史点亮时间为在历史使用屏幕过程中，各个屏幕区域被点亮的总时间，例如，第一屏幕区域A的历史点亮时间为2400个小时，第二屏幕区域B的历史点亮时间为2000个小时。
对于屏幕被预设有固定折叠线的情况下，每次折叠后，屏幕皆记录并累加不同屏幕区域的点亮时间，从而得到各个屏幕区域对应的历史点亮时间。
在一些实施例中，请参阅图2c，屏幕的背面设置有若干弯曲传感器2c1，弯曲传感器2c1用于检测屏幕的折叠度以及折叠位置，其中，弯曲传感器可以根据业务需求，沿着预设方向部分地或者全面地布设于屏幕上，因此，弯曲传感器能够部分地或者全面地检测到屏幕的弯曲区域位置、弯曲半径、弯曲角度等等。举例而言，在纵向上，各个弯曲传感器2c1分别沿着Y轴依次排列。在横向上，各个弯曲传感器2c1分别沿着X轴依次排列，其中，每个弯曲传感器2c1有规律地间隔预设距离进行排列。
当外力向屏幕施加压力而使屏幕弯曲时，其可以根据压力变化的传感器所处的位置而识别出弯曲区域。每个弯曲传感器2c1可以是电阻传感器或者微光纤传感器。在一些实施例中，弯曲传感器2c1还可以为加速度传感器、重力传感器、陀螺仪等等。
对于屏幕未被预设有规定折叠线，并且由用户自由折叠屏幕的情况下，屏幕通过弯曲传感器检测出的弯曲区域位置，从而得知折叠线所在的位置，进而得知能够显示画面的屏幕区域以及未能够显示画面的屏幕区域，再进而统计出各个屏幕区域对应的历史点亮时间。
在本实施例中，预设条件由用户根据业务需求自定义，例如，预设条件为预设点亮时间阈值范围，满足预设条件为历史点亮时间落入预设点亮时间阈值范围，未满足预设条件为历史点亮时间未落入预设点亮时间阈值范围。
如前所述，随着点亮时间越长，OLED材料的发光效率越低。随着点亮时间越短，OLED材料的发光效率不容易下降。在一些实施例中，请参阅图2d，S212包括：
S2121、比较任意两个屏幕区域对应的历史点亮时间；
S2122、根据比较结果，遍历出历史点亮时间为最长或最短的屏幕区域作为亮度异常区域。
在本实施例中，当屏幕被折叠成至少两个屏幕区域时，屏幕可通过比较任意两个屏幕区域对应的历史点亮时间，以此遍历出亮度异常区域。例如，屏幕区域A1对应的历史点亮时间t1为1500个小时，屏幕区域A2对应的历史点亮时间t2为1600个小时，屏幕区域A3对应的历史点亮时间t3为2000个小时，屏幕区域A4对应的历史点亮时间t4为2400个小时，通过比较，历史点亮时间由长到短的顺序为：t4>t3>t2>t1，因此，展开显示时，屏幕区域A4的亮度比较暗，屏幕区域A1的亮度比较亮，因此，可以选择屏幕区域A4作为亮度异常区域，亦可以选择屏幕区域A1作为亮度异常区域。
在一些实施例中，显示时，按照第一方向依序点亮屏幕中各行像素单元。因此，在获取亮度异常区域被点亮的起始时间的过程中，屏幕选择亮度异常区域中首先被点亮的首行像素单元对应的点亮时间作为起始时间。如前所述，屏幕排列有150行像素单元，其中，亮度异常区域为第51行至第150行的像素单元，则第51行像素单元为亮度异常区域中首行像素单元，并且，在展开显示时，第51行像素单元在亮度异常区域中首先被点亮的，则，第51行像素单元被点亮的点亮时间作为起始时间。
在一些实施例中，选择亮度异常区域中首先被点亮的首行像素单元对应的点亮时间作为起始时间的过程中，首先，屏幕确定亮度异常区域中首先被点亮的首行像素单元对应的目标行数，例如，第51行作为目标行数。
其次，屏幕根据目标行数与预设扫描时间，计算出切换时间，例如，预设扫描时间为每行0.2ms，计算出驱动电路打开各行像素单元的数量，因此，第51行像素单元的切换时间为0.2*(51-1)＝10ms。
最后，屏幕将切换时间作为起始时间。
在一些实施例中，调节亮度屏幕区域的亮度的方式多种多样，屏幕自动检测出亮度屏幕区域，自动调节亮度异常区域的亮度。或者，屏幕根据亮度调节指令实施亮度异常区域的亮度调节。请参阅图3a，S23包括：
S231、在显示灰阶下，获取亮度调节指令；
S232、自起始时间开始，根据亮度调节指令，调节亮度异常区域的亮度至预设亮度。
显示一帧画面时，向屏幕输入显示灰阶，通过伽马校正后，使得屏幕显示对应的亮度。因此，显示灰阶为展开显示时，屏幕显示该帧画面所对应的灰阶。未输入屏幕并辅助显示当前显示画面之用的灰阶作为中间灰阶或者未显示灰阶。可以理解的是，当未显示灰阶输入屏幕以使得屏幕显示一帧画面时，该未显示灰阶变成了“显示灰阶”，因此“未显示灰阶”与“显示灰阶”在输入屏幕作为显示之用是而被互相转化，并不是固定地作为“未显示灰阶”与“显示灰阶”。
如前所述，屏幕支持任何位数的灰阶显示，例如，支持全灰阶为0-255灰阶，当灰阶250输入屏幕以使得屏幕显示一帧画面时，灰阶250作为显示灰阶，然而，诸如灰阶0至249或者251至255等等作为未显示灰阶。
亮度调节指令的获取方式多种多样，举例而言，用户可操作屏幕的物理按键而触发亮度调节指令，例如，用户连续按动屏幕的POWER键三次，便可以进入亮度异常区域的亮度调节模式，再按动一次，便可以按照预设亮度调节比例调节亮度异常区域的亮度。
再举例而言，屏幕显示有亮度调试界面，亮度调试界面包括若干个亮度虚拟调节器，亮度调节指令由用户操作亮度虚拟调节器而触发屏幕将亮度比例系数封装于指令而分发出的，于是，屏幕便可以根据亮度调节指令调节亮度异常区域的亮度。
在一些实施例中，亮度调节指令包括亮度比例系数。请参阅图3b，S232包括：
S2321、根据亮度比例系数与预设伽马曲线，调节亮度异常区域的亮度至预设亮度；
S2322、记录不同显示灰阶对应的预设亮度；
S2323、计算出不同未显示灰阶对应的预设亮度；
S2324、记录各个未显示灰阶对应的预设亮度。
在本实施例中，亮度比例系数由用户自定义设置，例如，亮度比例系数对应的亮度调节范围为0至100％，其中，屏幕中的亮度调试界面显示有4组亮度虚拟调节器，每个亮度虚拟调节器对应的亮度调节范围皆为0至100％。请参阅图3c，调节时，用户选择在显示灰阶为255时，对亮度异常区域作调节，例如，用户操作第一组亮度调节虚拟调节器K1，输出的亮度比例系数为10％。用户选择在显示灰阶为250时，对亮度异常区域作调节，用户操作第二组亮度调节虚拟调节器K2，输出的亮度比例系数为5％。用户选择在显示灰阶为128时，对亮度异常区域作调节，用户操作第三组亮度调节虚拟调节器K3，输出的亮度比例系数为8％。用户选择在显示灰阶为32时，对亮度异常区域作调节，用户操作第四组亮度调节虚拟调节器K4，输出的亮度比例系数为6％。
预设伽马曲线由用户根据业务需求自行选择，例如，预设伽马曲线对应的函数为：
Figure PCTCN2019070063-appb-000001
其中，x为预设灰阶的灰阶数，L x为第x灰阶的目标亮度，L 255为第255灰阶的目标亮度，γ为伽马值。
一般的，用户根据预设伽马曲线，计算出不同灰阶对应的目标亮度，并根据不同灰阶与目标亮度的对应关系，构建gamma校正表，通过查找gamma校正表，可以知悉任意灰阶对应的目标亮度值。
在本实施例中，亮度比例系数作为k，其可与L x相乘或者作任何合适的运算，于是，其便可以计算出在显示灰阶下对应修正后的目标亮度。例如，修正后的伽马曲线对应的函数为：
Figure PCTCN2019070063-appb-000002
其中，L” x为修正后的目标亮度。
因此，屏幕便可以根据式二，调节亮度异常区域的亮度至预设亮度，亦即，预设亮度为修正后的目标亮度。例如，当显示灰阶为255时，k为10％，预设亮度(修正后的目标亮度)为350nit。当显示灰阶为250时，k为5％，预设亮度为330nit。当显示灰阶为128时，k为10％，预设亮度为160nit。
在上述预设亮度下，屏幕可以消除不同显示灰阶下的亮度异常区域与亮度正常区域之间的分界线，使得屏幕的各个屏幕区域的显示亮度均匀。
为了可靠快速地实现另一帧画面的亮度异常区域的亮度调节，屏幕记录不同显示灰阶对应的预设亮度，例如记录显示灰阶为255、250、128各自对应的预设亮度。
为了实现全灰阶下对亮度异常区域的亮度调节，屏幕还计算出不同未显示灰阶对应的预设亮度。在一些实施例中，计算出不同未显示灰阶对应的预设亮度的方式多种多样，例如，请参阅图3c，S2323包括：
S31、确定至少两组显示灰阶对应的预设亮度；
S32、根据插值法与至少两组显示灰阶对应的预设亮度，计算出插值函数；
S33、根据插值函数与每个未显示灰阶，计算出各个未显示灰阶对应的预设亮度。
在本实施例中，首先，为了计算非显示灰阶对应的预设亮度，屏幕需要确定至少两组显示灰阶对应的预设亮度，例如，屏幕确定(255，350)，(250，330)这两组显示灰阶对应的预设亮度。
其次，屏幕根据插值法，计算出插值函数，其中，插值法可以采用任意合适的方法，例如，采用线性插值算法，计算出的插值函数为线性插值函数。例如，令y＝ax+b，将(255，350)，(250，330)分别代入上式，得到y＝4x-670。因此，对于在灰阶250至255之间，其对应的线性插值函数为y＝4x-670，因此，当未显示灰阶为251时，其对应的预设亮度为334nit，当251作为显示灰阶输入屏幕时，其便可以将亮度异常区域的亮度调节至334nit。
同理，当屏幕再次得到(128，160)这一组显示灰阶对应的预设亮度时，将(128，160)、(250，330)分别代入上式，得到y＝1.39x-18.4。因此，对于在灰阶128至250之间，其对应的线性插值函数为y＝1.39x-18.4，因此，当未显示灰阶为150时，其对应的预设亮度为190nit，当150作为显示灰阶输入屏幕时，其便可以将亮度异常区域的亮度调节至190nit。
需要说明的是，在上述各个实施例中，上述各步骤之间并不必然存在一定的先后顺序，本领域普通技术人员，根据本申请实施例的描述可以理解，不同实施例中，上述各步骤可以有不同的执行顺序，亦即，可以并行执行，亦可以交换执行等等。
