Description

模型调整方法、装置、显示装置和存储介质 技术领域
本公开涉及显示技术领域，具体而言，涉及模型调整装置、模型调整方法、显示装置、计算机可读存储介质。
背景技术
随着显示技术的发展，显示面板的显示功能和显示方式逐渐多样化，某些显示面板在显示画面时，并不是点亮整个显示面板进行显示，而是仅点亮显示面板的部分区域进行显示。
这会导致显示面板中不同区域显示画面的时长存在差异，而显示画面时长较长的区域(例如简称为第一区域)，相对于显示画面时长较短的区域(例如简称为第二区域)，寿命衰减值更大，也即剩余寿命更短。
随着显示面板中元件寿命的衰减，显示面板的显示效果会发生变化，例如亮度会降低，而第一区域和第二区域由于寿命衰减值不同，会导致第一区域和第二区域的显示效果存在差异，例如第一区域的亮度低于第二区域的亮度。
针对上述问题，相关技术中通过引入先验模型对亮度进行补偿。但是由于不同的显示面板的参数存在离散性差异，而先验模型是预先设置的固定模型，难以针对不同显示面板进行准确的补偿，有可能存在过补偿、欠补偿等问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做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。

图1是根据本公开的实施例示出的一种模型调整装置的示意框图。本实施例所示的模型调整装置可以设置在显示面板中，可以为显示面板中的模块构成的装置，所述显示面板至少包括第一区域和第二区域，所述第一区域的寿命衰减值大于所述第二区域的寿命衰减值。
如图1所示，所述装置包括：
显示模块101，被配置为显示第一画面；
补偿模块102，被配置为通过预设模型计算出的补偿值对所述第一画面中所述第一区域和/或所述第二区域的亮度进行补偿；
接收模块103，被配置为接收用户对所述补偿值的调整值；
调整模块104，被配置为根据所述调整值调整所述预设模型中的参数。
在一个实施例中，所述显示面板包括有机发光二极管OLED显示面板。所述OLED显示面板中设置有有机发光层，有机发光层随着显示面板的使用，寿命会发生衰减，导致发光亮度降低，而且使用时间越长，寿命衰减值越大。
在一个实施例中，所述第一区域为非滑卷区，所述第二区域为滑卷区。
图2A是根据本公开的实施例示出的一种显示面板的示意图。图2B是根据本公开的实施例示出的一种通过第一区域显示画面的示意图。图2C是根据本公开的实施例示出的一种通过第一区域和第二区域显示画面的示意图。
如图2A所示，所述OLED显示面板可以为柔性面板，柔性面板可以包括非滑卷区(也可以称作固定区)和滑卷区。为了简化描述，以下将非滑卷区称作第一区域，将滑卷区称作第二区域。
其中，第二区域可以如图2A所示，包括设置在第一区域两侧的两块区域，也可以是仅设置在第一区域一侧的一块区域，或者以其他方式设置在第一区域周围的多块区域，具体可以根据需要进行设置，以下实施例主要在图2A所示结构下进行示例性说明。
用户在使用所述柔性面板时，如图2B所示，可以只通过第一区域显示画面，第二区域处于卷起状态；也可以如图2C所示，将第二区域展开，然后通过第一区域和第二区域一起显示画面。需要说明的是，本公开所有实施例中的显示第一画面，是指通过第一区域和第二区域一起显示第一画面。
由于无论如图2B单独通过第一区域显示画面，还是如图2C通过第一区域和第二区域一起显示画面，都需要点亮第一区域。这就导致第一区域的使用时长相对于第二区域的使用时长更长，而更长的使用时长则会导致更多的寿命衰减，也即第一区域的寿命衰减值大于所述第二区域的寿命衰减值，也可以表达为第一区域的剩余寿命低于第二区域的剩余寿命。
在这种情况下，在通过第一区域和第二区域一起显示画面时，第一区域的亮度相对于第二区域的亮度会较低，尤其在显示纯色画面时，用户会相对直观地观察到第一区域的亮度低于第二区域的亮度。
需要说明的是，本公开中的第一区域和第二区域并不限于图2A至图2C所示实施例中的非滑卷区和滑卷区，显示面板也不限于柔性面板，只要是显示面板中寿命衰减值不同的两个区域，都可以适用于本公开的技术方案。为了方便说明本申请的技 术方案，以下主要以图2A至图2C所示的显示面板作为示例进行说明。
由于第一区域的寿命衰减值大于所述第二区域的寿命衰减值，导致第一区域的亮度相对于第二区域的亮度会较低。为了克服这种问题，可以通过预设模型计算出补偿值，对第一画面中所述第一区域和/或第二区域的亮度进行补偿。
例如仅对第一区域的亮度进行补偿，那么可以通过补偿值仅提高第一区域的亮度，使得第一区域的亮度与第二区域的亮度相同(本公开所有实施例中描述的第一区域和第二区域的亮度相同，是指在第一区域和第二区域显示相同画面的情况下亮度相同)。
例如仅对第二区域的亮度进行补偿，那么可以通过补偿值仅降低第二区域的亮度，使得第二区域的亮度与第一区域的亮度相同。
例如对第一区域和第二区域的亮度进行补偿，那么可以通过补偿值提高第一区域和第二区域的亮度，其中，对于第一区域提高的亮度更多，使得第一区域的亮度与第二区域的亮度相同；或者可以通过补偿值提高第一区域的亮度并降低第二区域的亮度，使得第一区域的亮度与第二区域的亮度相同。
具体补偿方式本公开不作限制，可以根据需要进行设置。
在一个实施例中，所述预设模型包括但不限于Burn In算法模型，可以在显示面板显示第一画面时，确定第一区域和第二区域的寿命衰减值，例如根据第一区域和第二区域的使用时长确定寿命衰减值，使用时长越长，寿命衰减值越大。
由于预设模型为先验模型，其中的参数是预先设定的，在一定程度上(例如第一区域和第二区域的寿命衰减值差异较小时)可以适用于对亮度的补偿。但是由于显示面板的参数存在离散性差异(例如由于制作工艺导致)，例如有些显示面板的寿命衰减速度相对较快，这会导致第一区域和第二区域的寿命衰减值差异相对较大，按照预设模型确定的补偿值进行补偿，不足以将第一区域的亮度补偿为与第二区域的亮度相同，也即欠补偿；例如有些显示面板的寿命衰减速度相对较慢，这会导致第一区域和第二区域的寿命衰减值差异相对较小，按照预设模型确定的补偿值进行补偿，会导致将第一区域的亮度补偿的超过第二区域的亮度，也即过补偿。
针对上述采用预设模型计算出的补偿值进行补偿所存在的欠补偿、过补偿等问题。本公开的实施例提供了用户调整补偿值的功能，例如可以在显示面板中显示调整补偿值的输入窗口，用户可以根据需要确定如何调整补偿值，进而在窗口中输入对补 偿值的调整值。
例如在确定通过补偿值补偿后，第一区域显示的亮度高于第二区域的亮度，那么说明存在过补偿的问题，可以通过输入调整值，以降低补偿值；例如在确定通过补偿值补偿后，第一区域显示的亮度低于第二区域的亮度，那么说明存在欠补偿的问题，可以通过输入调整值，以提高补偿值。
进而可以根据用户输入的调整值调整预设模型中的参数，从而使得调整后的预设模型，适用于显示面板当前第一区域和第二区域的寿命衰减值的差异，以便后续根据调整后的预设模型得到的补偿值，可以准确地对第一区域和/或第二区域的亮度进行补偿，保证良好的显示效果。
图3是根据本公开的实施例示出的一种调整预设模型中参数的示意图。
如图3所示，以预设模型为Burn In算法模型为例，模型可以写入显示面板的显示驱动集成电路(Display Drive IC，DDIC)，例如具体是在DDIC的存储器(例如Flash)中。
本公开的实施例可以基于Linux内核、DRM(Direct Rendering Manager，直接渲染管理)显示框架实现。其中，可以采用DRM MIPI(Mobile Industry Processor Interface，移动行业处理器接口)通信API(Application Programming Interface，应用程序编程接口)实现调整DDIC中预设模型的参数。
还可以在内中编写基于Burn In算法的驱动，驱动中创建DDIC Burn In IP相关的寄存器参数节点，上层通过文件IO流实现设备节点的读写操作。
那么可以提供给用户输入调整值的UI(User Interface，用户界面)，用户可以在UI中输入调整值，并通过文件IO流传输至内核，进而再通过内核传输至DDCI，实现对DDCI对应Flash中预设模型的参数进行调整。
在一个实施例中，所述补偿模块，被配置为在所述第一寿命衰减值大于第一衰减阈值时，通过所述预设模型计算出的第一补偿值对所述第一区域进行补偿；
和/或，在所述第二寿命衰减值大于第二衰减阈值时，通过所述预设模型计算出的第二补偿值对所述第二区域进行补偿。
在一个实施例中，由于在寿命衰减值相对较小时，第一区域和第二区域的亮度之间差异相对较小，可以不必通过预设模型计算出的补偿值进行补偿；而在寿命衰减 值相对较大时，第一区域和第二区域的亮度之间差异相对较大，才有必要通过预设模型计算出的补偿值进行补偿。
因此，针对第一区域和第二区域，可以分别设置衰减阈值，在寿命衰减值大于衰减阈值时，才通过预设模型计算出的补偿值进行补偿。例如对于第一区域可以设置第一衰减阈值，在第一寿命衰减值大于第一衰减阈值时，通过预设模型计算出的第一补偿值对第一区域进行补偿；对于第二区域可以设置第二衰减阈值，在第二寿命衰减值大于第二衰减阈值时，通过预设模型计算出的第二补偿值对第二区域进行补偿。
由于寿命衰减值与剩余寿命是对应的，寿命衰减值越大，剩余寿命越小，因此，也可以设置寿命阈值，在剩余寿命小于寿命阈值时，才通过预设模型计算出的补偿值进行补偿。
图4A、图4B和图4C是根据本公开的实施例示出的通过预设模型计算出的补偿值进行补偿的开关示意图。
显示面板显示的窗口中可以包含第一区域(固定区)的第一剩余寿命，以及第二区域(滑卷区)的第二剩余寿命，其中，剩余寿命可以以百分比的形式表示。
窗口中还可以包含控制通过预设模型计算出的补偿值进行补偿的开关，该开关可以自动开启或关闭，例如第一区域的第一剩余寿低于第一寿命阈值时，开关可以自动从关闭状态变为开启状态，进而通过预设模型计算出的第一补偿值对第一区域进行补偿；例如第二区域的第二剩余寿低于第二寿命阈值时，开关可以自动从关闭状态变为开启状态，进而通过预设模型计算出的第二补偿值对第二区域进行补偿。
当然，上述开关也可以手动开启或关闭，例如用户可以根据剩余寿命选择将开关从关闭状态变为开启状态，或者从开启状态变为关闭状态。其中，在开关自动从关闭变为开启状态后，若用户手动将开关又变回关闭状态，那么后续可以不再自动将开关变为开启状态，或者在预设时长内不再自动将开关变为开启状态。
需要说明的是，第一寿命阈值和第二寿命阈值可以相等，也可以不相等，具体可以根据需要进行设置，以下为了方便示例，以第一寿命阈值和第二寿命阈值相等，例如均为95％，进行示例性说明。
在第一阶段，显示面板几乎未使用。如图4A所示，第一区域的第一剩余寿命和第二区域的第二剩余寿命都是100％。可以确定第一剩余寿命大于第一寿命阈值，第二剩余寿命大于第二寿命阈值，那么两个区域对应开关都处于关闭状态，对于第一区 域和第二区域，都不必通过预设模型计算出的补偿值进行补偿。
在第二阶段，显示面板使用了一段时间。如图4B所示，由于第一区域的使用时长相对于第二区域的使用时长更长，因此寿命衰减更多，剩余寿命更少，也即第一剩余寿命少于第二剩余寿命，例如第一剩余寿命为92％，第二剩余生命为98％。可以确定第一剩余寿命小于第一寿命阈值，第二剩余寿命大于第二寿命阈值，第一区域对应的开关处于开启状态，第二区域对应的开关处于关闭状态，从而通过预设模型计算出的第一补偿值对第一区域进行补偿，其中，第一补偿值可以是预设模型根据第一寿命衰减值或第一剩余寿命计算得到。
在第三阶段，显示面板使进一步又使用了一段时间。如图4B所示，例如第一剩余寿命为88％，第二剩余生命为94％。可以确定第一剩余寿命小于第一寿命阈值，第二剩余寿命也小于第二寿命阈值，第一区域对应的开关处于开启状态，第二区域对应的开关也处于开启状态，从而通过预设模型计算出的第一补偿值对第一区域进行补偿，通过预设模型计算出的第二补偿值对第二区域进行补偿，其中，第一补偿值可以是预设模型根据第一寿命衰减值或第一剩余寿命计算得到，第二补偿值可以是预设模型根据第二寿命衰减值或第二剩余寿命计算得到。
如图4A、图4B和图4C所示，在窗口中除了显示剩余寿命和开关等内容，还可以显示返回上一级操作列表(例如“设置”操作列表)的返回按键，以及进入“寿命补偿校准”操作界面的按键，用户可以在“寿命补偿校准”操作界面中输入对所述补偿值的调整值。
以下通过几个实施例对用户调整所述补偿值进行示例性说明。
在一个实施例中，所述显示模块，还被配置为在显示所述第一画面时，显示所述第一画面的对应的亮度参数和/或灰阶参数。
在一个实施例中，所述显示模块，所述亮度参数包括伽马曲线(Gamma band)；和/或所述灰阶参数包括所述第一画面对应颜色的灰阶值。
其中，所述第一画面可以是通过第一区域和第二区域一起显示的纯色画面，例如红色(Red，R)画面、绿色(Green，G)画面、蓝色(Blue，B)画面等。
在显示第一画面时，还可以显示第一画面对应的参数，例如亮度参数、灰阶参数。其中，灰阶参数例如可以是绑点的灰阶，可以设置m个绑点，m为大于或等于1的整数，后续实施例主要以m等于8进行示例，例如绑点为灰阶255，那么对应红色 R、绿色G和蓝色B，可以分别表示为R255、G255、B255；亮度参数可以是伽马曲线，例如可以设置n条伽马曲线，band#1至band#n，n为大于或等于1的整数，例如n可以等于10、12等，每条伽马曲线在255灰阶(白色画面的灰阶)时对应的目标亮度可以不同。
例如第一画面为灰阶参数为R255的情况下，亮度参数为band#1的纯红色画面，那么在第一画面中显示的亮度参数为band#1，显示的灰阶参数为R255；
例如第一画面为灰阶参数为R255的情况下，亮度参数为band#2的纯红色画面，那么在第一画面中显示的亮度参数为band#2，显示的灰阶参数为R255；
例如第一画面为灰阶参数为B255的情况下，亮度参数为band#2的纯蓝色画面，那么在第一画面中显示的亮度参数为band#2，显示的灰阶参数为B255。
具体的第一画面可以根据需要进行设置，还可以通过调整灰阶参数、亮度参数等，以控制显示面板显示所需的第一画面。用户通过观察第一画面，可以判断出经过预设模型计算的补偿值进行补偿后，第一画面中第一区域和第二区域的差异，以便做出准确的调整。
以下主要在亮度参数为band#1，显示的灰阶参数为R255的情况下，对本公开的实施例进行示例性说明。
需要说明的是，预设模型计算出补偿值对第一区域和/或所述第二区域的亮度进行补偿，主要包括两种情况：情况1，预设模型计算出第一补偿值仅对第一区域进行补偿；情况2，预设模型计算出第一补偿值对第一区域进行补偿，且计算出第二补偿值对第二区域进行补偿。还可以根据需要补充设置第三种补偿情况：情况3，预设模型计算出第二补偿值仅对第二区域进行补偿。
以下实施例主要针对情况1和情况2进行说明，其中，情况1是在第一剩余寿命小于第一寿命阈值，第二剩余寿命大于第二寿命阈值，仅对第一区域进行补偿的情况，情况2是在第一剩余寿命小于第一寿命阈值，第二剩余寿命小于第二寿命阈值，对第一区域和第二区域都进行补偿的情况。
图5A是根据本公开的实施例示出的一种用户调整补偿值的示意图。
如图5A所示，例如通过显示面板按照灰阶参数为R255，亮度参数为band#1显示纯红色画面，预设模型计算出第一补偿值对第一区域的亮度进行补偿后，第一区域的亮度仍然低于第二区域的亮度，也即对于第一区域存在欠补偿的问题。
那么可以在第一区域中(例如图5A所示的第一区域的底部)显示预设模型计算出第一补偿值，以及对于第一补偿值的调整按键，例如包括第一补偿值左侧的减小第一补偿值的按键和第一补偿值右侧的提高第一补偿值的按键，还可以包括对于调整后第一补偿值的确认按键。
由于存在欠补偿问题，因此用户可以提高第一补偿值，例如图5A所示，将第一补偿值从3提高到4，显示面板可以根据调整后的第一补偿值对第一区域的亮度进行补偿，并基于补偿后的亮度显示第一区域中的内容。例如图5A所示，在第一补偿值为4的情况下，第一区域的亮度和第二区域的亮度相同，从而解决的欠补偿的问题，那么用户可以点击确认按键，确认对于第一补偿值的调整值，也即+1。
显示面板可以基于调整值，调整DDCI(对应存储器)中预设模型中的参数，从而使得后续基于调整后预设模型计算出的第一补偿值对第一区域进行补偿，可以避免上述欠补偿问题。
图5B是根据本公开的实施例示出的另一种用户调整补偿值的示意图。
如图5B所示，例如通过显示面板按照灰阶参数为R255，亮度参数为band#1显示纯红色画面，预设模型计算出第一补偿值对第一区域的亮度进行补偿后，第一区域的亮度高于第二区域的亮度，也即对于第一区域存在过补偿的问题。
那么可以在第一区域中(例如图5B所示的第一区域的底部)显示预设模型计算出第一补偿值，以及对于第一补偿值的调整按键，例如包括第一补偿值左侧的减小第一补偿值的按键和第一补偿值右侧的提高第一补偿值的按键，还可以包括对于调整后第一补偿值的确认按键。
由于存在过补偿问题，因此用户可以降低第一补偿值，例如图5B所示，将第一补偿值从5提高到4，显示面板可以根据调整后的第一补偿值对第一区域的亮度进行补偿，并基于补偿后的亮度显示第一区域中的内容。例如图5B所示，在第一补偿值为4的情况下，第一区域的亮度和第二区域的亮度相同，从而解决的过补偿的问题，那么用户可以点击确认按键，确认对于第一补偿值的调整值，也即-1。
显示面板可以基于调整值，调整DDCI(对应存储器)中预设模型中的参数，从而使得后续基于调整后预设模型计算出的第一补偿值对第一区域进行补偿，可以避免上述过补偿问题。
图5C是根据本公开的实施例示出的又一种用户调整补偿值的示意图。
如图5C所示，例如通过显示面板按照灰阶参数为R255，亮度参数为band#1显示纯红色画面，预设模型计算出第一补偿值对第一区域的亮度进行补偿预设模型计算出第二补偿值对第而区域的亮度进行补偿后，第一区域的亮度低于第二区域的亮度，这可以理解为对于第一区域存在欠补偿的问题，也可以理解为对于第二区域存在过补偿的问题。
那么可以在第一区域中(例如图5C所示的第一区域的底部)显示预设模型计算出第一补偿值，以及对于第一补偿值的调整按键，例如包括第一补偿值左侧的减小第一补偿值的按键和第一补偿值右侧的提高第一补偿值的按键，还可以包括对于调整后补偿值的确认按键。
以及在第二区域中(例如图5C所示的第二区域的底部)显示预设模型计算出第二补偿值，以及对于第二补偿值的调整按键，例如包括第二补偿值左侧的减小第一补偿值的按键和第二补偿值右侧的提高第二补偿值的按键，还可以包括对于调整后补偿值的确认按键。
由于上述问题可以理解为对于第一区域存在欠补偿的问题，也可以理解为对于第二区域存在过补偿的问题，所以既可以提高第一补偿值，也可以降低第二补偿值。
而由于第二区域的寿命衰减值小于第一区域的寿命衰减值，所以第二区域中的结构更接近出厂时的情况，所以可以认为预设模型计算出的第二补偿值相对于第一补偿值更为准确，因此在这种情况下，可以先单独提高第一补偿值，如果单独提高第一补偿值不足以使得第一区域和第二区域的亮度相同，再尝试提高第一补偿值，且降低第二补偿值。
以单独提高第一补偿值为例，由于对于第一区域存在欠补偿问题，因此用户可以提高第一补偿值，例如图5C所示，将补偿值从4提高到6，显示面板可以根据调整后的补偿值对第一区域的亮度进行补偿，并基于补偿后的亮度显示第一区域中的内容。例如图5C所示，在补偿值为6的情况下，第一区域的亮度和第二区域的亮度相同，从而解决对于第一区域的欠补偿问题，那么用户可以点击确认按键，确认对于第一补偿值的调整值，也即+2。
显示面板可以基于调整值，调整DDCI(对应存储器)中预设模型中的参数，从而使得后续基于调整后预设模型计算出的补偿值对第一区域进行补偿，可以避免上述过补偿问题。
图5D是根据本公开的实施例示出的又一种用户调整补偿值的示意图。
如图5D所示，例如通过显示面板按照灰阶参数为R255，亮度参数为band#1显示纯红色画面，预设模型计算出第一补偿值对第一区域的亮度进行补偿预设模型计算出第二补偿值对第而区域的亮度进行补偿后，第一区域的亮度高于第二区域的亮度，这可以理解为对于第一区域存在过补偿的问题，也可以理解为对于第二区域存在欠补偿的问题。
那么可以在第一区域中(例如图5D所示的第一区域的底部)显示预设模型计算出第一补偿值，以及对于第一补偿值的调整按键，例如包括第一补偿值左侧的减小第一补偿值的按键和第一补偿值右侧的提高第一补偿值的按键，还可以包括对于调整后补偿值的确认按键。
以及在第二区域中(例如图5D所示的第二区域的底部)显示预设模型计算出第二补偿值，以及对于第二补偿值的调整按键，例如包括第二补偿值左侧的减小第一补偿值的按键和第二补偿值右侧的提高第二补偿值的按键，还可以包括对于调整后补偿值的确认按键。
由于上述问题可以理解为对于第一区域存在过补偿的问题，也可以理解为对于第二区域存在欠补偿的问题，所以既可以降低第一补偿值，也可以提高第二补偿值。
而由于第二区域的寿命衰减值小于第一区域的寿命衰减值，所以第二区域中的结构更接近出厂时的情况，所以可以认为预设模型计算出的第二补偿值相对于第一补偿值更为准确，因此在这种情况下，可以先单独降低第一补偿值，如果单独降低第一补偿值不足以使得第一区域和第二区域的亮度相同，再尝试降低第一补偿值，且提高第二补偿值。
以单独降低第一补偿值为例，由于对于第一区域存在过补偿问题，因此用户可以降低第一补偿值，例如图5D所示，将补偿值从8降低到6，显示面板可以根据调整后的补偿值对第一区域的亮度进行补偿，并基于补偿后的亮度显示第一区域中的内容。例如图5D所示，在补偿值为6的情况下，第一区域的亮度和第二区域的亮度相同，从而解决的对于第一区域的过补偿问题，那么用户可以点击确认按键，确认对于第一补偿值的调整值，也即-2。
显示面板可以基于调整值，调整DDCI(对应存储器)中预设模型中的参数，从而使得后续基于调整后预设模型计算出的补偿值对第一区域进行补偿，可以避免上 述过补偿问题。
需要说明的是，对于补偿值的调整范围，可以是预先设定的，以免用户过度调整补偿值导致显示异常，甚至造成显示面板受损。
例如显示面板可以根据DDIC对应Flash中的预设模型，以及回读DDCI当前寄存器配置，确定显示面板中像素电路的数据范围等参数，进而根据预设模型、数据范围等参数确定在每个灰阶参数、每个亮度参数下的调整范围。
在一个实施例中，所述显示模块，还被配置为根据用户对所述亮度参数和/或所述灰阶参数的调整，显示调整后的第一画面。
如图5A至图5D所示，在调整补偿值的窗口中可以显示第一画面的对应的亮度参数、灰阶参数等，并且在显示参数的位置可以提供下拉按键，通过点击下拉按键可以显示下拉菜单，例如在亮度参数的下拉菜单中可以显示当前亮度参数以外的其他亮度参数，在灰阶参数的下拉菜单中可以显示当前灰阶参数以外的其他灰阶参数。
用户可以通过选择其他亮度模型调整第一画面的亮度参数，也可以通过选择其他灰阶模型调整第一画面的灰阶参数，显示面板可以根据调整后的亮度参数、灰阶参数调整所显示的第一画面。
需要说明的是，对于调整前的第一画面，用户可以不调整补偿值，而是在调整后的第一画面中调整补偿值，那么显示面板可以仅根据一次对于补偿值的调整值调整预设模型中的参数；或者，对于调整前的第一画面，用户可以调整补偿值，在调整后的第一画面中，用户可以再次调整补偿值，并且用户可以多次通过调整亮度参数、灰阶参数来调整第一画面，并针对每次调整后的第一画面都调整补偿值，那么显示面板可以根据多次对于补偿值的调整值，也即多个补偿值，调整预设模型中的参数。
以下通过几个实施例对预设模型计算补偿值的过程进行示例性说明。
图6是根据本公开的实施例示出的一种灰阶补偿值与寿命衰减值之间的关系示意图。
在一个实施例中，通过预设模型计算出的补偿值可以用于补偿亮度，而亮度与灰阶相关，因此补偿值可以是灰阶补偿值offset。
如图6所示，对于红色子像素R、绿色子像素G、蓝色子像素B而言，随着寿命衰减值(可以理解为使用时长)的增加，亮度会下降，因此需要的补偿值也就越大。
例如以data表示寿命计数(使用时长或者寿命衰减值)，灰阶补偿值offset与data之间的关系可以为：
offset＝LUT(data)       ……式1；
其中，LUT为look up table的缩写，表示查找关系表，也即在第一关系表中保存有data与offset的对应关系，进而通过查找第一关系表可以确定data对应的offset。
但是offset还与亮度、显示灰阶等因素相关，因此，还需要从亮度、显示灰阶等方面对offset进行修正，以得到修正后的offset’作为补偿值。
其中，亮度可以通过DDIC中存储的Gamma band确定，DDIC中可以存储有1至12组and，每个band在不同灰阶下对应不同亮度，因此，可以确定亮度修正系数a与band之间的第二关系表，进而可以基于下式确定a：
a＝LUT(band)         ……式2；
也即可以通过查找a与band之间的第二关系表，确定band对应的a；
另外，还可以确定显示灰阶(gray)与灰阶修正系数b之间的第三关系表，进而可以基于下式确定b：
b＝LUT(gray)        ……式3；
也即可以通过查找b与gray之间的第三关系表，确定gray对应的b。
进而可以得到offset修正的offset’：
offset’＝offset*a*b        ……式4；
那么基于offset’补偿值对于当前显示画面的亮度(可以视作灰阶Gray)进行补偿，补偿后的灰阶为Gray’：
Gray’＝Gray+offset’     ……式5。
图7是根据本公开的实施例示出的一种灰阶与补偿值之间的关系示意图。
如图7所示，以n条Gamma band为例，例如Band#1至Band#n，n为大于或等于1的整数。坐标系中横坐标为当前显示画面的灰阶Gray，纵坐标为补偿值offset’。
其中，当前显示画面的灰阶Gray可以视作图5A至图5D所示的灰阶参数中的灰阶值(也即白色画面时的灰阶)，Band#1至Band#n可以视作图5A至图5D所示的亮度参数。
例如灰阶参数对应8个绑点，那么用户可以通过调整灰阶参数为这8个绑点对应的任一灰阶，显示面板则可以显示用户所选择绑点灰阶对应的画面。例如亮度参数对应n个band，那么用户可以通过调整亮度参数为这n个band对应任一band，显示面板则可以用户所选择band对应的画面。
因此用户选择灰阶参数和亮度参数后，预设模型确定的补偿值，就是在图7坐标系中所选择band与所选择绑点灰阶的交点对应的补偿值offset’。用户在所选择的灰阶参数和亮度参数对应的第一画面中调整offset’，就是调整所述交点对应的补偿值offset’，例如提高补偿值，就是将所述交点的纵坐标提高，降低补偿值，就是将所述交点的纵坐标降低。
在调整所述交点后，每个band上Gray与offset’之间的关联关系就会发生改变，这也会导致band发生变化。由于offset’改变，上述式4就需要改变，由于band改变，上述式2就需要改变。而关于式3和式1，虽然b和offset参数式4的运算，但是由于式4中offset’改变可以单独改变式2，也即调整a来适应，所以式3和式1可以不变，可以单独调整a适应offset’的改变会导致式2改动过大，而且在某些情况下单独调整a尚不足以适应offset’的改变，所以一般情况下，需要对式3和式1也做出调整，确保得到的b和offset代入式4后，在offset’改变的情况下式4仍然成立。
由于式1、式2和式3的调整，那么式1对应的第一关系表、式2对应的第二关系表、式3对应第三关系表也会发生调整，可以将调整后的式1、式2和式3，也即调整后的第一关系表、第二关系表、第三关系表，作为调整预设模型中参数的依据。
在一个实施例中，所述补偿模块，还被配置为通过所述预设模型计算出的补偿值对每次调整后的第一画面中所述第一区域和/或所述第二区域的亮度进行补偿；所述接收模块，还被配置为接收用户对所述预设模型每次计算出的补偿值的调整值；所述调整模块，被配置为根据多次接收到的调整值调整所述预设模型中的参数。
而根据图7可知，其中包括n条band，以及多个绑点，在一个灰阶参数和一个亮度参数对应的第一画面中调整补偿值，仅能调整图7中所示的一个交点，据此调整调整预设模型中的参数，调整后的预设模型也只能对该交点对应的画面计算出适当的补偿值，而对于其他交点对应的画面则难以计算出适当的补偿值。
因此，可以调整图7中的多个交点，例如调整所有交点。而每个交点对应的灰阶参数、亮度参数，都可以在图5A至图5D中选择，因此用户可以尽量调整灰阶参数、 亮度参数，例如遍历灰阶参数和亮度参数的组合，并在每种组合下调整补偿值，从而实现对图7中所有交点对应的offset’都进行了调整，据此，可以确保调整后的预设模型对所有交点对应的画面都能计算出适当的补偿值。
其中，对于用户每次调整后灰阶参数和/或亮度参数后得到的第一画面，预设模型都可以计算出补偿值，用户可以对预设模型每次计算出的补偿值进行调整，进而可以根据用户每次调整补偿值所输入的调整值调整所述预设模型中的参数。
在一个实施例中，所述调整模块，被配置为根据所述调整值调整灰阶与修正值之间的关联关系，其中，所述修正值基于灰阶补偿值和亮度修正系数以及灰阶修正系数确定；根据调整后的关联关系调整灰阶补偿值与寿命衰减值之间的第一关系表、亮度修正系数与所述亮度值之间第二关系表，以及灰阶修正系数与所述灰阶值之间第三关系表；根据调整后的第一关系表、第二关系表和第三关系表，调整所述预设模型中的参数。
用户调整灰阶参数和亮度参数后，预设模型确定的补偿值，例如为基于图7坐标系中亮度参数对应band与绑点灰阶的交点对应的补偿值offset’。用户在所选择的灰阶参数和亮度参数对应的第一画面中调整offset’，就是调整所述交点对应的补偿值offset’，例如提高补偿值，就是将所述交点的纵坐标提高，降低补偿值，就是将所述交点的纵坐标降低。
在调整所述交点后，每个band上Gray与offset’之间的关联关系就会发生改变，这也会导致band发生变化。由于offset’改变，上述式4就需要改变，由于band改变，上述式2就需要改变。而关于式3和式1，虽然b和offset参数式4的运算，但是由于式4中offset’改变可以单独改变式2，也即调整a来适应，所以式3和式1可以不变，可以单独调整a适应offset’的改变会导致式2改动过大，而且在某些情况下单独调整a尚不足以适应offset’的改变，所以一般情况下，需要对式3和式1也做出调整，确保得到的b和offset代入式4后，在offset’改变的情况下式4仍然成立
由于式1、式2和式3的调整，那么式1对应的第一关系表、式2对应的第二关系表、式3对应第三关系表也会发生调整，可以根据调整后的式1、式2和式3，也可以理解为调整后的第一关系表、第二关系表、第三关系表，调整预设模型中的参数。
由于上述式1、式2和式3可以通过关系表的形式表达，难以直接参与运算，因此可以先将上述式1、式2和式3输入转换函数fx()，用于将上述式1、式2和式3 转换为数值或者向量，用于对预设模型的参数进行调整。
图8是根据本公开的实施例示出的一种亮度补偿方法的示意流程图。
如图8所示，显示装置通过第一区域和第二区域显示第一画面，DDIC开启Burn In计数，用于记录寿命衰减值。在寿命衰减值大于衰减阈值的情况下，可以开启补偿，通过预设模型计算补偿值，对第一区域和/或第二区域的亮度进行补偿(在此之后可以选择显示如图4A至图4C所示的补偿控制UI)，而在命衰减值不大于衰减阈值的情况下，则不必开启补偿。
用户可以观察补偿效果是否满意，如果满意的话(例如观察到第一显示区域和第二显示区域之间的亮度没有差异)，则不必调整补偿值，如果不满意的话(例如观察到第一显示区域和第二显示区域之间的亮度存在差异)，可以调整补偿值。例如用户可以进入调整补偿值的窗口，例如图5A至图5D所示的窗口，进而对补偿值进行调整。
基于用户对补偿值的调整，可以确定调整值，进而基于调整值可以对上述式1、式2和式3进行调整，也即调整每个式子对应的LUT()。进而根据调整后的LUT()调整预设模型中的参数，例如首先根据调整后的LUT()确定DDIC中预设模型的新配置参数，进而将新配置参数经由内核驱动发送至DDCI，DDIC据此更新预设模型。后续基于更新后的预设模型确定补偿值，可以对第一区域、第二区域进行良好的补偿。
