本公开的一些实施例提供了一种显示模组的参数调节方法、电子设备、显示模组的参数调节系统、显示模组、显示装置、计算机可读存储介质及计算机程序产品。以下对显示模组的参数调节方法、电子设备、显示模组的参数调节系统、显示模组、显示装置、计算机可读存储介质及计算机程序产品分别进行介绍。
如图1所示，本公开的一些实施例提供一种显示装置100，该显示装置100可以是显示不论运动(例如，视频)还是固定(例如，静止图像)的且不论文字还是的图像的任何装置。更明确地说，预期所述实施例可实施在多种电子装置中或与多种电子装置关联，所述多种电子装置例如(但不限于)移动电话、无线装置、个人数据助理(PDA)、手持式或便携式计算机、GPS接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如，里程表显示器等)、导航仪、座舱控制器和/或显示器、相机视图的显示器(例如，车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构(例如，对于一件珠宝的图像的显示器)等。

在一些实施例中，如图2所示，显示模组110包括显示面板10、柔性电路板20、驱动芯片以及其他电子配件等。
上述显示面板10的类型包括多种，可以根据实际需要选择设置。
示例性地，上述显示面板10可以为电致发光显示面板，例如，可以为有机发光二极管(Organic Light Emitting Diode，简称OLED)显示面板、量子点发光二极管(Quantum Dot Light Emitting Diodes，简称QLED)显示面板等，本公开实施例对此不做具体限定。
下面以上述显示面板10为OLED显示面板为例，对本公开的一些实施例进行示意性说明。
在一些实施例中，如图2和图3所示，上述显示面板10具有显示区A，以及设置在显示区至少一侧的周边区B。图2和图3中均以周边区B围绕显示区A为例进行示意。
其中，显示区A为显示图像的区域，显示区A被配置为设置子像素P。周边区B为不显示图像的区域，周边区B被配置为设置显示驱动电路，例如，栅极驱动电路和源极驱动电路。
示例性地，如图2和图3所示，上述显示面板10包括设置在衬底1的一侧、且位于显示区A的多个子像素P。该多个子像素P排列为多行和多列，每行包括第一方向X排列为的多个子像素P，每列包括沿第二方向Y排列的多个子像素P。其中，每行子像素P可以包括多个子像素P，每列子像素P可以包括多个子像素P。
此处，第一方向X和第二方向Y相互交叉。第一方向X和第二方向Y之间的夹角可以根据实际需要选择设置。示例性地，第一方向X和第二方向Y之间的夹角可以为85°、89°或90°等。
其中，如图3和图4所示，子像素P包括设置于衬底1上的发光器件11和像素驱动电路12，像素驱动电路12包括多个薄膜晶体管121。薄膜晶体管121包括有源层1211、源极1212、漏极1213和栅极1214，源极1212和漏极1213分别与有源层1211接触。沿垂直于衬底1且远离衬底1的方向，发光器件11包括依次设置的第一电极层111、发光功能层112以及第二电极层113，第一电极层111和多个薄膜晶体管121中作为驱动晶体管的薄膜晶体管的源极1212或漏极1213电连接，图4中以第一电极层111和薄膜晶体管121的源极1212电连接进行示意。
需要说明的是，上述源极1212和漏极1213可以互换，即图4中的1212表示漏极，图4中的1213表示源极。
在一些实施例中，发光功能层112仅包括发光层。在另一些实施例中，发光功能层112除包括发光层外，还包括电子传输层(election transporting layer，简称ETL)、电子注入层(election injection layer，简称EIL)、空穴传输层(hole  transporting layer，简称HTL)和空穴注入层(hole injection layer，简称HIL)中的至少一个。
在一些实施例中，如图4所示，显示面板10还包括像素界定层114，像素界定层114包括多个开口区，一个发光器件11设置于一个开口区中。
在一些实施例中，如图4所示，显示面板10还包括设置于薄膜晶体管121和第一电极111之间的第一平坦层115。
在一些实施例中，如图4所示，显示面板10还包括设置于发光器件11远离衬底1的一侧的封装层2。其中，封装层2可以为封装薄膜，还可以为封装盖板。
在一些实施例中，如图2和图3所示，上述显示面板10还可以包括设置在衬底1的一侧、且位于显示区A的多条栅线GL以及多条数据线DL。其中，该多条栅线GL沿第一方向X延伸，该多条数据线DL沿第二方向Y延伸。
示例性地，可以将沿第一方向X排列成一行的子像素P称为同一行子像素P，将沿第二方向Y排列成一列的子像素P称为同一列子像素P。同一行子像素P可以与一条栅线GL电连接，同一列子像素P可以与一条数据线DL电连接。
其中，一条栅线GL可以与同一行子像素P中的多个像素驱动电路12电连接，一条数据线DL可以与同一列子像素P中的多个像素驱动电路12电连接。
在像素驱动电路中，扫描晶体管与复位晶体管大部分时间都是关闭的，需要较低的漏电速度；开关晶体管和驱动晶体管大部分时间都是开启的，需要较高的电荷迁移率。结合铟镓锌氧化物薄膜晶体管(英文：Thin Film Transistor，简称TFT)在低刷新率下的稳定性高和制作成本较低的优点，以及低温多晶硅TFT高电荷迁移率的优点，产生了低温多晶氧化物(英文：Low Temperature Polycrystalline Oxide，简称LTPO)像素驱动电路。
在LTPO像素驱动电路中，扫描晶体管与复位晶体管采用N型的铟镓锌氧化物TFT，开关晶体管和驱动晶体管采用低温多晶硅TFT，这样可以以低生产成本实现高的电荷迁移率、稳定性和可扩展性。
上述像素驱动电路的结构包括多种，可以根据实际需要选择设置。下面结合图5和图6，以LTPO像素驱动电路包括8个晶体管T与1个电容器CST为例，对子像素P的结构及工作过程进行示意性说明。
示例性地，如图5所示，像素驱动电路12包括8个晶体管T与1个电容器CST。像素驱动电路12的第一晶体管T1和第七晶体管T7的控制极均与复 位信号端RESET耦接，第二晶体管T2和第四晶体管T4的控制极均与第一扫描信号端GATE1耦接，第八晶体管T8的控制极与第二扫描信号端GATE2耦接。第一晶体管T1和第七晶体管T7均为复位晶体管，第二晶体管T2、第四晶体管T4和第八晶体管T8为扫描晶体管。第三晶体管T3的控制极与电容器CST的一端耦接，第五晶体管T5和第六晶体管T6的控制极均与使能信号端EM耦接；第三晶体管T3为驱动晶体管，第五晶体管T5和第六晶体管T6为开关晶体管，第一晶体管T1、第二晶体管T2、第三晶体管T3、第四晶体管T4、第五晶体管T5、第六晶体管T6和第七晶体管T7均为P型的低温多晶硅TFT，第八晶体管T8为N型的铟镓锌氧化物TFT。
其中，一个帧周期(图6中以1F示意出)包括复位阶段P1、充电阶段P2和发光阶段P3。
在复位阶段P1，第一晶体管T1和第七晶体管T7均在来自复位信号端RESET的复位信号Reset的控制下导通，第八晶体管T8在来自第二扫描信号端GATE2的第二扫描信号Gate2的控制下导通，第一节点N1被重置为来自第一初始化信号端VINT1的初始化电压信号的电压，第二节点N2被重置为来自第二初始化信号端VINT2的初始化电压信号的电压。
在充电阶段P2，第二晶体管T2和第四晶体管T4均在来自第一扫描信号端GATE1的第一扫描信号Gate1的控制下导通，第八晶体管T8在来自第二扫描信号端GATE2的第二扫描信号Gate2的控制下导通，第三晶体管T3在第一节点N1的电压的控制下导通，电容器CST被写入来自数据信号端DATA的数据信号Data。
在发光阶段P3，第五晶体管T5和第六晶体管T6均在使能信号端EM的使能信号Em的控制下导通，第三晶体管T3在第一节点N1的控制下导通，以向发光器件输出驱动电流信号。
其中，为了降低显示面板10的功耗，显示面板10具有高频驱动模式和低频驱动模式，其中低频模式可用于静态画面的显示。在低频驱动模式中，一个低频周期包括一个刷新帧和多个保持帧。需要说明的是，一个刷新帧和一个保持帧可以均为上述一个帧周期。图7中以一个刷新帧和一个保持帧为例进行示意。
但是，在低频驱动模式中，由于显示面板的刷新频率降低，导致人眼对显示面板所显示的画面的闪烁的感知更加敏感，从而产生人眼能够感知到显示面板所显示的画面出现闪烁的问题。
经研究发现，参阅图6和图7，发光延迟时间Td(一帧的充电阶段开始 与发光阶段开始的时间差)、发光器件的阳极的电压VINT2、以及驱动晶体管T3的源极在保持帧1F(2)接收的来自数据信号端的保持电压V keep，这些参数会影响画面的闪烁值。其中，若要获得闪烁值较低的画面，不同的线路排布的显示面板10(参阅图2)所需要的上述参数可能不完全相同。
此处，如图5、图6和图7所示，发光延迟时间Td也是驱动晶体管T3的特性回复时间，该特性回复时间的长短影响驱动晶体管T3状态，进而影响发光器件11发光的亮度。发光器件11的阳极在一帧内的电压VINT2(包括在刷新帧1F(1)发光器件11所接收的初始化信号，即第一子初始化信号VINT 2-1，在保持帧1F(2)发光器件11所接收的初始化信号，即第二子初始化信号VINT 2-2)，均会影响发光器件11的启亮速度，影响最终发光器件11的亮度。在保持帧1F(2)接收的来自数据信号端的保持电压V keep，同样会影响驱动晶体管T3状态，进而影响发光器件11发光的亮度。
基于此，参阅图8，本公开实施例所提供的显示模组110所包括的驱动芯片30，存储有优选发光延迟时间PR Td，驱动芯片30被配置为根据优选发光延迟时间PR Td，生成发光信号，并将发光信号传输至显示面板10，驱动显示面板10发光。在这种情况下，可以降低显示面板10在低频驱动模式中所显示的画面亮度的浮动，从而降低显示面板10的闪烁值(Flicker)，改善人眼感知到显示面板10所显示的画面出现闪烁的问题。
其中，上述优选发光延迟时间PR Td可以根据本公开实施例所提供的显示模组110的参数调节方法得到，具体可以参考下文，本公开在此不做赘述。
在一些实施例中，驱动芯片30中还存储有优选第一子初始化信号PR VINT 2-1、优选第二子初始化信号PR VINT 2-2和优选数据保持信号PR V keep中的至少一者。示例性地，驱动芯片30中还存储有优选第一子初始化信号PR VINT 2-1、优选第二子初始化信号PR VINT 2-2和优选数据保持信号PR V keep。在这种情况下，驱动芯片30被配置为根据优选发光延迟时间PR Td、优选第一子初始化信号PR VINT 2-1、优选第二子初始化信号PR VINT 2-2和优选数据保持信号PR V keep，生成发光信号，将发光信号传输至显示面板10，驱动显示面板10发光。在这种情况下，可以通过优选第一子初始化信号PR VINT 2-1、优选第二子初始化信号PR VINT 2-2控制发光器件11的启亮速度，从而调整最终发光器件11的亮度，以进一步地降低显示面板10的闪烁值(Flicker)，改善人眼感知到显示面板10所显示的画面出现闪烁的问题。并且，可以通过优选数据保持信号PR V keep控制驱动晶体管T3源极的电压，调整驱动晶体管T3的状态，从而调整最终发光器件11的亮度，以进一步地降低显示面板10的 闪烁值(Flicker)，改善人眼感知到显示面板10所显示的画面出现闪烁的问题。
其中，上述优选第一子初始化信号PR VINT 2-1、优选第二子初始化信号PR VINT 2-2和优选数据保持信号PR V keep均可以根据本公开实施例所提供的显示模组110的参数调节方法得到，具体可以参考下文，本公开在此不做赘述。
本公开的一些实施例所提供的显示模组110的参数调节方法，参阅图7和图8，该显示模组110能够在低频驱动模式下工作，低频驱动模式包括多个低频周期，一个低频周期包括一个刷新帧1F(1)和至少一个保持帧1F(2)。
在此基础上，如图9所示，该参数调节方法包括S100～S400。
S100：设定发光延迟时间的初始值Td 0和多个指定灰阶1～S。
上述步骤中，S≥1，且S为正整数。发光延迟时间的初始值Td 0可以为0～30个行扫描时段。示例性地，发光延迟时间的初始值Td 0为0个行扫描时段、10个行扫描时段和30个行扫描时段中的任一者。多个指定灰阶1～S可以根据实际情况进行选择，本公开在此不做限定。图19中以5个指定灰阶进行示意。
需要说明的是，一个行扫描时段＝1秒÷刷新频率÷扫描行数。示例性地，显示面板的刷新频率为120HZ，扫描行数为1000行，则一个行扫描时段为0.0083ms。
S200：基于发光延迟时间的初始值Td 0，步进式调整发光延迟时间Td，直至调整后的发光延迟时间Td m超出发光延迟时间的预设范围，得到在发光延迟时间Td的预设范围内的多个发光延迟时间Td 0～Td m-1。
上述步骤中，m≥1，且m为正整数。发光延迟时间Td的预设范围为0～30个行扫描时段。其中，步进式调整发光延迟时间Td可以是，基于发光延迟时间的初始值Td 0，以第一设定步进值Step 1从低到高或从高到低调整发光延迟时间Td，每次调整均得到一个发光延迟时间Td m。此处，第一设定步进值Step 1可以为1h(行扫描时段)～5h，例如，第一设定步进值Step 1可以为1h、2h、3h、4h和5h中的任一者。
示例性地，发光延迟时间的初始值Td 0为0个行扫描时段，第一设定步进值Step 1为1h。在此情况下，从低到高调整发光延迟时间Td，每次调整1h，直至调整后的发光延迟时间Td m的值大于30h。
示例性地，发光延迟时间的初始值Td 0为30个行扫描时段，第一设定步进值Step 1为5h。在此情况下，从高到低调整发光延迟时间Td，每次调整5h， 直至调整后的发光延迟时间Td m的值小于0h。
S300：在每个发光延迟时间Td(Td 0～Td m-1)下，获取显示模组110多个指定灰阶1～S下的多个闪烁值。
上述步骤中，可以在每次步进式调整发光延迟时间Td之前，获取该调整前的发光延迟时间Td下，显示模组110在多个指定灰阶1～S下的多个闪烁值。
也就是说，在步进式调整发光延迟时间Td的过程中，同时获取每次调整前对应的发光延迟时间Td在多个指定灰阶1～S下的多个闪烁值，从而在得到多个发光延迟时间Td 0～Td m-1的同时，得到每个发光延迟时间Td(Td 0～Td m-1)下，显示模组110在多个指定灰阶1～S下的多个闪烁值。
其中，显示模组110在多个指定灰阶1～S下的多个闪烁值可以是，显示模组110在第一子初始化信号的初始值VINT 2-1.0以及多个指定灰阶1～S下的多个闪烁值；也可以是，显示模组110在多个第一子初始化信号VINT 2-1以及多个指定灰阶1～S下的多个闪烁值，具体可以参考下文，本公开在此不做赘述。第一子初始化信号VINT 2-1为在刷新帧发光器件11所接收的初始化信号。
S400：根据多个发光延迟时间Td 0～Td m-1对应的多个闪烁值，从多个发光延迟时间Td 0～Td m-1中确定优选发光延迟时间PR Td。
上述步骤中，在获取显示模组110在第一子初始化信号的初始值VINT 2-1.0以及多个指定灰阶1～S下的多个闪烁值的情况下，从多个发光延迟时间Td 0～Td m-1中确定优选发光延迟时间PR Td的方法，与在获取显示模组110在多个第一子初始化信号VINT 2-1以及多个指定灰阶1～S下的多个闪烁值的情况下，从多个发光延迟时间Td 0～Td m-1中确定优选发光延迟时间PR Td的方法并不相同，具体可以参考下文，本公开在此不做赘述。
此处，可以将该优选发光延迟时间PR Td存储至驱动芯片30中，驱动芯片30可以根据优选发光延迟时间PR Td，生成发光信号，并将发光信号传输至显示面板10，驱动显示面板10发光。在这种情况下，可以降低显示面板10在低频驱动模式中所显示的画面亮度的浮动，降低显示面板10的闪烁值(Flicker)，改善人眼感知到显示面板10所显示的画面出现闪烁的问题。
在一些实施例中，如图10所示，上述S300包括S310～S330。
S310：设定第一子初始化信号的初始值VINT 2-1.0。
上述步骤中，第一子初始化信号VINT 2-1为在刷新帧发光器件所接收的初始化信号。其中，第一子初始化信号的初始值VINT 2-1.0可以为-6V～-1V。示例性地，第一子初始化信号的初始值VINT 2-1.0可以为-1V、-3V、-5V和-6V中的任一者。
S320：基于第一子初始化信号的初始值VINT 2-1.0，步进式调整第一子初始化信号VINT 2-1，直至调整后的第一子初始化信号VINT 2-1.n超出第一子初始化信号VINT 2-1的预设范围，得到在第一子初始化信号VINT 2-1的预设范围内的多个第一子初始化信号VINT 2-1.0～VINT 2-1.n-1。
上述步骤中，n≥1，且n为正整数。多个发光延迟时间Td 0～Td m-1的数量为M个，多个第一子初始化信号VINT 2-1.0～VINT 2-1.n-1的数量为N个，M个发光延迟时间Td 0～Td m-1和N个第一子初始化信号VINT 2-1.0～VINT 2-1.n-1组成M×N个第一参数组合，一个第一参数组合包括一个发光延迟时间Td和一个第一子初始化信号VINT 2-1。
此外，第一子初始化信号VINT 2-1的预设范围为-6V～-1V。其中，步进式调整第一子初始化信号VINT 2-1是指，基于第一子初始化信号的初始值VINT 2-1.0，以第二设定步进值Step 2从低到高或从高到低或调整第一子初始化信号VINT 2-1，每次调整均得到一个第一子初始化信号VINT 2-1.n。此处，第二设定步进值Step 2可以为0.1V～0.5V，例如，第二设定步进值Step 2可以为0.1V、0.2V、0.3V、0.4V和0.5V中的任一者。
示例性地，第一子初始化信号的初始值VINT 2-1.0为-6V，第二设定步进值Step 2为0.1V。在此情况下，从低到高调整第一子初始化信号VINT 2-1，每次调整0.1V，直至调整后的第一子初始化信号VINT 2-1.n的值大于-1V。
示例性地，第一子初始化信号的初始值VINT 2-1.0为-1V，第二设定步进值Step 2为0.5V。在此情况下，从高到低调整第一子初始化信号VINT 2-1，每次调整0.5V，直至调整后的第一子初始化信号VINT 2-1.n的值小于-6V。
S330：在M×N个第一参数组合中的每个第一参数组合下，获取显示模组110在多个指定灰阶1～S下的多个闪烁值。
上述步骤中，可以在每次步进式调整发光延迟时间Td之前，获取该调整前的发光延迟时间Td下，显示模组110在N个第一子初始化信号VINT 2-1和多个指定灰阶1～S下的多个闪烁值。
也就是说，在步进式调整发光延迟时间Td的过程中，在每次调整发光延迟时间Td之前，先步进式调整第一子初始化信号VINT 2-1，并在每次步进式调第一子初始化信号VINT 2-1之前，同时获取该调整前的第一子初始化信号VINT 2-1下，显示模组110在多个指定灰阶1～S下的多个闪烁值，从而在得到多个发光延迟时间Td 0～Td m-1的同时，得到M×N个第一参数组合中的每个第一参数组合下，显示模组110在多个指定灰阶1～S下的多个闪烁值。
其中，一个第一参数组合对应的多个闪烁值为一组闪烁值。在此基础上， 如图11所示，上述S400包括S410～S430。
S410：从M个发光延迟时间Td 0～Td m-1中，确定每个第一子初始化信号VINT 2-1(VINT 2-1.0～VINT 2-1.n-1)对应的目标发光延迟时间AM Td。
上述步骤中，目标发光延迟时间AM Td为第一子初始化信号VINT 2-1在M个发光延迟时间Td 0～Td m-1下对应的M组闪烁值组中，收敛性最高的一组闪烁值所对应的发光延迟时间Td。
示例性地，如图19所示，闪烁值组的收敛性可以通过方差进行判定，方差越小，收敛性越高。例如，在第一子初始化信号为VINT 2-1.0+Step 2×3的情况下，其对应的目标发光延迟时间AM Td为Td 0+Step 1×2。此处，图19中十字交叉处为VINT 2-1.0+Step 2×3对应的闪烁值。
S420：从N个第一子初始化信号VINT 2-1.0～VINT 2-1.n-1中，确定优选第一子初始化信号PR VINT 2-1。
上述步骤中，确定优选第一子初始化信号PR VINT 2-1，以便于S430中，通过该优选第一子初始化信号PR VINT 2-1确定优选发光延迟时间PR Td。其中，确定优选第一子初始化信号PR VINT 2-1，具体可以参考下文，本公开在此不做赘述。
S430：将与优选第一子初始化信号PR VINT 2-1对应的目标发光延迟时间AM Td，确定为优选发光延迟时间PR Td。
上述步骤中，可以根据上述S410所得到的第一子初始化信号VINT 2-1对应的目标发光延迟时间AM Td，找出优选第一子初始化信号PR VINT 2-1对应的目标发光延迟时间AM Td，作为优选发光延迟时间PR Td。
