具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本申请，并不被配置为限定本申请。对于本领域技术人员来说，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请更好的理解。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在不脱离本申请的精神或范围的情况下，在本申请中能进行各种修改和变化，这对于本领域技术人员来说是显而易见的。因而，本申请意在覆盖落入所对应权利要求(要求保护的技术方案)及其等同物范围内的本申请的修改和变化。需要说明的是，本申请实施例所提供的实施方式，在不矛盾的情况下可以相互组合。
在阐述本申请实施例所提供的技术方案之前，为了便于对本申请实施例理解，本申请首先对相关技术中存在的问题进行具体说明：
显示屏可设置有亮度调整的控件，可以通过调节亮度调整的档位，来调整显示屏的显示亮度。同一灰阶下，不同档位对应的目标显示亮度不同，例如高档位对应的目标显示亮度大于低档位对应的目标显示亮度。另外，由于不同档位的亮度需求是不同的，为了降低显示屏的功耗，至少部分不同的档位可以对应不同的电源电压值。电源电压值包括低电平电源电压(ELVSS)值，低电平电源电压端可以与显示屏的发光元件的阴极电连接，从而低电平电源电压(ELVSS)值可提供给发光元件的阴极。
为了使人眼较为适应，显示屏的明暗变化需要均匀过渡，例如亮度比 值大于0且小于某个预设值的情况下，可认为均匀过渡；该预设值可以预先确定，如根据厂家的特性要求。其中，亮度比值Li、Li-1分别表示显示屏在相邻的两个档位下的显示亮度，Li为显示屏在相邻档位中上一档位下的显示亮度，Li-1为显示屏在相邻档位中下一档位下的显示亮度。
然而，发明人研究发现，由于部分不同的档位可以对应不同的电源电压值，也就是部分档位对应的电源电压值相对于与其相邻的档位对应的电源电压值存在突变，而电源电压值也会影响显示屏的亮度，导致电源电压值存在突变的档位对应的显示亮度也会存在突变，进而导致存在突变的档位对应的亮度比值小于0，也就是该档位对应的亮度比值出现了负点，具体表现为显示屏在该档位下出现了亮度反转，导致显示屏的明暗变化无法均匀过渡，影响用户的使用体验。
鉴于发明人的上述研究发现，本申请实施例提供了一种显示屏的显示驱动方法、装置、设备及介质，能够解决显示屏的明暗变化无法均匀过渡的问题。
下面首先对本申请实施例所提供的显示屏的显示驱动方法进行介绍。
如图1所示，本申请实施例所提供的显示屏的显示驱动方法包括步骤S110至S130。
S110，获取显示屏在亮度调整的当前档位；
S120，若当前档位符合第一预设条件，则获取当前档位对应的数据电压初始值及数据电压补偿值，其中，第一预设条件包括当前档位对应的电源电压值与其直接相邻的上一或下一档位对应的电源电压值不同，且当前档位为指定档位之外的档位，指定档位之外的档位对应的电源电压值是根据指定档位对应的电源电压值确定的，不同指定档位对应的电源电压值不同；
S130，基于数据电压初始值及数据电压补偿值，驱动显示屏显示。
示例性的，为了保证显示屏具有良好的显示画质，可以对显示屏进行伽马(gamma)调试。而显示屏的亮度调整可具有多个档位，如果在每个档位下均进行伽马调试，则伽马调试的时间会比较长。为了避免伽马调试的时间过长，可以在多个档位中选取一些档位作为指定档位，并仅在指定档位下进行伽马调试，确定显示屏在指定档位下对应的数据电压值。指定档位之外的其它档位对应的数据电压初始值可根据指定档位对应的数据电压值来确定，这样可不必再在指定档位之外的其它档位下对显示屏进行伽马调试，进而压缩伽马调试的数据，减少伽马调试所需的时间，提高生产效率。
本文中，为了区分指定档位和指定档位之外的档位，将指定档位之外的其它档位对应的数据电压值称为数据电压初始值。
例如，如图2所示，可以在多个档位中选取9个档位作为指定档位，分别为指定档位A至指定档位I。图2中，横轴表示档位，纵轴表示亮度。具体的，横轴可以表示档位对应的寄存器值，档位对应的寄存器值从小到大可以包括0到4095。指定档位A可以为最高档位，指定档位I可以为最低档位。例如，指定档位A在最大灰阶值下对应的亮度可以为700nit，指定档位I在最大灰阶值下对应的亮度可以为2nit。
示例性的，可以预先设置各指定档位对应的电源电压值。例如指定档位A至指定档位I对应的电源电压值可以为a至i，而指定档位之外的档位对应的电源电压值可以根据指定档位对应的电源电压值来确定。不同指定档位对应的电源电压值可以不同。
例如，指定档位B对应的电源电压值为-2.0V，指定档位C对应的电源电压值为-2.3V，指定档位B和指定档位C之间包括档位b1和档位c1，档位b1和档位c1对应的电源电压值可以介于-2.0V与-2.3V之间。例如，档位b1对应的电源电压值可以为-2.1V，档位c1对应的电源电压值可以为-2.2V。示例性的，档位b1和档位c1对应的数据电压初始值可以根据指定档位B和指定档位C对应的数据电压值确定。
以档位b1和档位c1与其直接相邻的档位对应的电源电压值不同为例，在显示屏的亮度调整为档位b1或档位c1的情况下，如果仅基于档位b1和 档位c1对应的数据电压初始值来驱动显示屏显示，由于档位b1和档位c1相对于其直接相邻的档位其电源电压值存在突变，如图3所示，则会出现显示屏在档位b1和档位c1下的亮度比值出现负点，导致显示屏的明暗变化不符合均匀过渡的要求。图3中，横轴表示档位，纵轴表示亮度比值具体的，横轴可以表示档位对应的寄存器值。
示例性的，与当前档位直接相邻的上一挡位或下一挡位可以是指定档位，也可以是指定档位之外的档位。而根据本申请实施例提供的显示屏的显示驱动方法，在当前档位对应的电源电压值与其直接相邻的档位对应的电源电压值不同，且当前档位为指定档位之外的档位的情况下，也就是在当前档位为电源电压值突变对应的档位的情况下，不再仅基于当前档位对应的数据电压初始值来驱动显示屏显示，而是也获取了当前档位对应的数据电压补偿值，并基于当前档位对应的数据电压初始值及数据电压补偿值来驱动显示屏显示，由于利用数据电压补偿值，对存在电源电压值突变的当前档位进行了补偿，从而可以避免显示屏在当前档位下的亮度比值出现负点，解决由于电源电压值突变导致的显示屏的明暗变化无法均匀过渡的问题。
在一些可选的实施例中，本申请实施例提供的显示屏的显示驱动方法还可以包括：若当前档位不符合第一预设条件，则基于当前档位对应的数据电压初始值，驱动显示屏显示。
例如当前档位为指定档位，或者当前档位为指定档位之外的档位，但当前档位对应的电源电压值与其直接相邻的档位对应的电源电压值相同，则可认为当前档位对应的电源电压值不存在突变，当前档位对应的亮度不会出现反转，这种情况下，可不必对当前档位对应的数据电压初始值进行补偿。
在一些可选的实施例中，可以先判断当前档位是否符合第一预设条件。如图4所示，本申请实施例提供的显示屏的显示驱动方法还可以包括步骤 S121至S123。
S121，判断指定档位之外的档位对应的电源电压值是否为基于内插方式确定的；
S122，若是，且当前档位为相邻两个指定档位之间的档位，当前档位对应的电源电压值与其直接相邻的上一档位对应的电源电压值不同，则确定当前档位符合第一预设条件；
S123，若否，且当前档位为指定档位直接相邻的档位，则确定当前档位符合第一预设条件。
如上文介绍的，可以预先设置各指定档位对应的电源电压值，而指定档位之外的档位对应的电源电压值可以根据指定档位对应的电源电压值来确定。
例如，可以根据指定档位对应的电源电压值，并基于内插方式来确定指定档位之外的档位对应的电源电压值。具体的，内插方式可包括线性内插方式，仍以图3中的指定档位B和指定档位C为例，指定档位B对应的电源电压值为-2.0V，指定档位C对应的电源电压值为-2.3V，指定档位B和指定档位C之间包括档位b1和档位c1的情况下，利用线性内插的方式，可以得到档位b1对应的电源电压值可以为-2.1V，档位c1对应的电源电压值可以为-2.2V。
又例如，仍以图3为例，每相邻两个指定档位之间可以包括多个档位，为便于理解，以指定档位B对应的寄存器值为100，指定档位C对应的寄存器值为70，指定档位B和指定档位C之间可包括分别对应寄存器值71～99的多个档位。这里将指定档位B对应的电源电压值标记为VB，将指定档位C对应的电源电压值标记为VC，并以每6个档位共用一个电源电压值，且与指定档位相邻的下一档位和指定档位的电源电压值相同为例。例如，寄存器值95～100对应的电源电压值可以为VB，寄存器值89～94对应的电源电压值可以为V2，寄存器值83～88对应的电源电压值可以为V3，寄存器值77～82对应的电源电压值可以为V4，寄存器值71～76对应的电源电压值可以为V5，寄存器值65～70对应的电源电压值可以为VC，其中，电源电压值V2、V3、V4、V5是根据电源电压值VB、VC并利用线性内插的方 式确定的。以寄存器值89对应的档位为例，其直接相邻的上一档位对应的寄存器值为90，而寄存器值89、90对应的电源电压值均为V2，因此，寄存器值为71、77、83、89、95对应的档位可以理解为不存在电源电压值突变。而寄存器值为76、82、88、94对应的档位可以理解为存在电源电压值突变，若当前档位的寄存器值为76、82、88、94中的任意一个，则可确定当前档位符合第一预设条件。
例如，可以根据指定档位对应的电源电压值，且不基于内插方式来确定指定档位之外的档位对应的电源电压值。具体的，仍以图2为例，每相邻两个指定档位之间可以包括一个或多个档位，这里为便于理解，以指定档位B对应的寄存器值为100，指定档位C对应的寄存器值为70，指定档位B和指定档位C之间可包括分别对应寄存器值71～99的多个档位。例如，寄存器值71～99的多个档位对应的电源电压值与指定档位B对应的电源电压值相同，均为VB，指定档位C对应的电源电压值为VC。因此虽然指定档位C与其直接相邻的上一档位(即寄存器值71对应的档位)对应的电源电压值不同，由于在指定档位下是进行了实际的伽马调试的，发明人发现实际情况是在指定档位直接相邻的上一档位(例如，寄存器值71对应的档位)存在亮度比值出现负点的情况，因此在不基于内插方式来确定指定档位之外的档位对应的电源电压值的情况下，若当前档位为指定档位直接相邻的上一档位，则确定当前档位符合所述第一预设条件。
根据本申请实施例，通过先确定指定档位之外的档位对应的电源电压值的确定方式，并对不同确定方式用不同的条件来判断当前档位是否符合第一预设条件，如此能够保证判断结果的准确性。示例性的，也可以预先对显示屏进行亮度调整，例如按照从亮到暗的方式依次改变显示屏的档位，并确定哪些档位存在亮度比值出现负点的情况，对于亮度比值为负值且绝对值较小的档位，可以筛除忽略不计，记录筛选后的亮度比值为负 的档位，将这些档位记录为目标档位。可以判断当前档位是否属于目标档位，若是，则可认为当前档位符合预设条件。
在一些可选的实施例中，在当前档位下，不同灰阶值对应的数据电压补偿值可以相同。例如，以灰阶位数为8bit为例，在当前档位下，0～255灰阶对应的数据电压补偿值可以是相同的。由于在当前档位下，不同灰阶值共用同一个数据电压补偿值，这样可以减少需要存储的数据量，降低成本；并且，在确定不同灰阶值所共用的数据电压补偿值的时候，可以仅基于某一个灰阶值来确定，例如测试画面可以是某一个灰阶值下的画面，这样就不必使显示屏点亮不同的灰阶值对应的画面，可缩短确定数据电压补偿值所需的调试时间。
作为一个可选的实施例，任意一个灰阶值在当前档位下对应的数据电压补偿值均与显示屏的最大灰阶值在当前档位下对应的数据电压补偿值相同。灰阶值与亮度正相关，灰阶值越大亮度则越大，因此灰阶值越大对应的亮度比值的负点越明显，最大灰阶值在当前档位下对应的数据电压补偿值能够解决最大灰阶值对应的亮度比值的负点问题的情况下，理论上，该数据电压补偿值也能够解决其它灰阶值对应的亮度比值的负点问题。
示例性的，最大灰阶值可以包括255灰阶。
示例性的，可以仅基于显示屏的最大灰阶值来确定当前档位对应的数据电压补偿值。
可以理解的是，显示屏对应的存储器中可以仅存储最大灰阶值在当前档位下对应的数据电压补偿值。
在一些可选的实施例中，为了提高补偿精度，可以将显示屏的灰阶范围划分为多个灰阶区间，在当前档位下，同一灰阶区间内的不同灰阶值对应的数据电压补偿值相同，不同灰阶区间对应的数据电压补偿值可以不同。可以理解的是，显示屏对应的存储器中可以各个灰阶区间在当前档位下对应的数据电压补偿值。
同理，基于最大灰阶值在当前档位下对应的数据电压补偿值能够解决最大灰阶值对应的亮度比值的负点问题的情况下，任意一个灰阶区间在当前档位下对应的数据电压补偿值与该灰阶区间内的最大灰阶值在当前档位 下对应的数据电压补偿值可以相同。示例性的，可以仅基于该灰阶区间内的最大灰阶值来确定当前档位对应的数据电压补偿值。可以理解的是，显示屏对应的存储器中可以仅存储各个灰阶区间内的最大灰阶值在当前档位下对应的数据电压补偿值。
如上文介绍的，可仅在指定档位下对显示屏进行伽马调试，确定显示屏在指定档位下对应的数据电压值，指定档位之外的其它档位对应的数据电压初始值可根据指定档位对应的数据电压值来确定，进而压缩伽马调试时间。
在一些可选的实施例中，数据电压初始值可以根据至少两个指定档位对应的数据电压值并利用线性内插的方式来确定。如此，由于指定档位对应的数据电压值是根据实际的伽马调试得到的，即使没有在指定档位之外的其它档位下对显示屏进行实际的伽马调试，也能确保其它档位对应的数据初始电压是比较准确的；另外，这样可以仅存储指定档位对应的数据电压值，可以大大减少需要存储的数据量，显示屏对应的存储器的容量可以降低，存储器的容量与面积通常正相关，也就是可以降低存储器的面积，从而降低成本。
示例性的，在当前档位符合第一预设条件的情况下，指定档位可以包括第一指定档位和第二指定档位，当前档位位于第一指定档位和第二指定档位之间，可认为前档位、第一指定档位和第二指定档位对应的数据电压值符合线性关系，这样当前档位对应的数据电压初始值可以根据第一指定档位和第二指定档位分别对应的数据电压值，并利用线性内插的方式来确定。
由于相邻档位之间的显示情况是比较接近的，这样相邻档位对应的数据电压值可看成符合线性关系。示例性的，可根据与其它档位直接相邻的两个指定档位对应的数据电压值，并利用线性内插的方式来确定其它档位对应的数据电压初始值。
示例性的，在当前档位符合第一预设条件的情况下，当前档位位于第一指定档位和第二指定档位之间，第一指定档位和第二指定档位可以为直接相邻的两个指定档位，当前档位对应的数据电压初始值可以根据以下关 系式(1)来确定：
其中，V1表示第一指定档位对应的数据电压值，V2表示第二指定档位对应的数据电压值，V0表示当前档位对应的数据电压初始值，DBV1表示第一指定档位对应的寄存器值，DBV2表示第二指定档位对应的寄存器值，DBV0表示当前定档位对应的寄存器值。
例如，如图3所示，以当前档位为档位b1为例，则指定档位B可以为第一指定档位，指定档位C可以为第二指定档位。
示例性的，可以利用51寄存器来表示亮度调整的档位。档位对应的寄存器值可以存储为十六进制的形式，在计算当前档位对应的数据电压初始值时，可以将十六进制转换为十进制。
示例性的，显示屏可显示一定的灰阶范围，在同一档位下，不同灰阶值对应的数据电压的值不同。在上述关系式(1)中，V1、V2、V0表示同一灰阶值下的数据电压的值。例如，以255灰阶为例，V1表示255灰阶在第一指定档位下对应的数据电压值，V2表示255灰阶在第二指定档位下对应的数据电压值，V0表示255灰阶在当前档位下对应的数据电压初始值。
例如，当前档位为档位b1，当前档位对应的数据电压补偿值为offset，则在S130中，可以基于当前档位对应的数据电压初始值V0与数据电压补偿值offset的和，驱动显示屏显示。
示例性的，在任意一个指定档位下对显示屏进行伽马调试时，可以从灰阶范围中选取一些灰阶绑点，仅在灰阶绑点处对显示屏进行伽马调试，得到各个灰阶绑点对应的数据电压值。灰阶绑点之外的灰阶值对应的数据电压值可以根据灰阶绑点对应的数据电压值，并利用线性差值的方式计算得到。
示例性的，不同指定档位所对应的灰阶绑点可以相同。
在一些可选的实施例中，在当前档位符合第一预设条件的情况下，如图5所示，至少一个灰阶值在当前档位下对应的数据电压补偿值的确定过程可以包括S510至S550：
S510，获取灰阶值在当前档位下对应的数据电压值；
S520，设置灰阶值对应的初始补偿值；
S530，基于灰阶值在当前档位下对应的数据电压值以及初始补偿值，驱动显示屏显示灰阶值下的测试画面并采集显示屏的显示亮度值；
S540，若采集的显示亮度值符合第二预设条件，则直接将初始补偿值作为灰阶值在当前档位下对应的数据电压补偿值；
S550，若采集的显示亮度值不符合第二预设条件，则调整初始补偿值，直至基于灰阶值在当前档位下对应的数据电压值以及调整后的初始补偿值，显示屏的显示亮度值符合第二预设条件，则将调整后的初始补偿值作为灰阶值在当前档位下对应的数据电压补偿值。
第二预设条件包括其中，
Ln表示采集的在当前档位下的显示亮度值，L(n+1)表示显示屏在上一档位下的显示亮度值，上一档位与当前档位直接相邻。
在S510中，以255灰阶为例，如图3所示，比如当前档位为档位b1，指定档位B和指定档位C为与档位b1直接相邻的两个指定档位，则可将255灰阶在指定档位B下对应的数据电压值代入上述式(1)中的V1，将255灰阶在指定档位C下对应的数据电压值代入上述式(1)中的V2，将指定档位B对应的寄存器值代入上述式(1)中的DBV1，将指定档位C对应的寄存器值代入上述式(1)中的DBV2，将档位b1对应的寄存器值代入上述式(1)中的DBV0，则可求出档位b1对应的数据电压初始值V0。
S520中，可以根据经验设置初始补偿值。
在S530中，可以基于灰阶值在当前档位下对应的数据电压值和初始补偿值之和，点亮显示屏，使显示屏显示该灰阶值下的测试画面。
示例性的，显示屏可以包括多种颜色的子像素，S520具体可以包括：设置各颜色的子像素在灰阶值下各自对应的初始补偿值。对应的，该灰阶值下的测试画面可以包括该灰阶值下的白色画面。相对于用该灰阶值下的单色画面来调试，可以减少点亮次数。
可以理解的是，根据预设条件可知，需要获取该灰阶值在与当前档位直接相邻的上一档位下对应的显示亮度值。例如，比如当前档位为档位b1， 指定档位B为与档位b1直接相邻的上一档位，则获取该灰阶值在指定档位B下对应的显示亮度值。
根据本申请实施例提供的数据电压补偿值的确定方式，由于是实际对显示屏进行调试的，可保证所得数据电压补偿值的准确性。
