参照图2，本申请的一实施例提供一种数据处理方法，所述数据处理方法包括：
步骤S10，确定运用预设灰阶拍摄的图像数据；
在本实施例中，在要做显示数据的补偿时，即，要做DeMura数据时，需要运用CCD相机拍摄显示的画面，通过CCD相机来拍摄显示的画面的图像数据，而拍摄显示的画面是，采用预设灰阶来拍摄，例如，预设灰阶为灰阶A，或者也可以是为灰阶B，预设的灰阶可以是RGB三色的灰阶，或者单色的灰阶，根据需求设置。采用灰阶拍摄的图像数据为灰阶数据，采用的RGB拍摄的为RGB数据。而所述CCD的分辨率和精度需求比较高，采用高精度和高分辨率的CCD镜头来拍摄。拍摄检测画面时一般采用高精度高分别率的CCD相机，相机分辨率的选择取决于被检测面板的分辨率，大小，拍摄距离以及Demura补偿的精度。为了达到最佳的检测和补偿效果。相机最终得到的数据一定要是XYZ，且后续的计算均是基于相机拍照得到的XYZ数据。CCD拍摄一定要符合人眼识别的效果，以及达到人眼的分辨能力。
在通过CCD拍摄到显示装置显示画面的图像数据后，确定运用预设灰阶拍摄的图像数据，通过远程或者拷贝的方式确定到图像数据。
步骤S20，根据所述图像数据确定显示缺陷的第一补偿数据；
在确定了图像数据后，根据所述图像数据确定显示缺陷的第一补偿数据。所述第一补偿数据为除预设灰阶数据之外需要补偿的数据。在确定图像数据后，根据图像数据识别Mura（显示缺陷）的存在，在识别到Mura后，根据Mura来确定显示缺陷的第一补偿数据。补偿数据是与Mura对应的，Mura识别的好，补偿数据也确定的更加准确，关键在于如何识别Mura的存在。当然，Mura识别后，Mura对应有补偿数据，或者根据Mura类型和严重程度对应设置有不同的尝试数据，所述补偿数据为灰阶数据补偿。在其他实施例中也可以是RGB颜色数据的补偿，颜色数据的补偿和灰阶数据补偿之间可转换。
可选地，在确定运用预设灰阶拍摄的图像数据的步骤之后，还包括：根据图像数据和预设识别算法确定显示设备是否存在显示缺陷；在存在显示缺陷时，执行根据所述图像数据确定显示缺陷的第一补偿数据的步骤。所述预设识别算法包括对比度增强、亮度梯度、计算色差的识别方式。具体的经过对比增强后，原本很微弱不易识别的Mura可以明显被识别，当然还有很多其它的方法，例如比较Pixel与周围pixel的亮度差异，计算亮度梯度，计算色差等方法。
步骤S30，根据所述第一补偿数据和预设灰阶的数据生成显示缺陷的补偿数据。
在确定了显示缺陷的第一补偿数据后，这部分补偿数据为需要烧录至存储器中的数据，具体的，所述根据所述第一补偿数据和预设灰阶的数据生成显示缺陷的补偿数据的步骤的步骤之后，还包括：将所述第一补偿数据烧录至显示设备的存储器中；在补偿显示画面时，根据烧录的第一补偿数据和所述预设灰阶的数据生成的补偿数据完成显示缺陷的修复。而作为预设灰阶部分的数据不用写入存储器中，或者说不用每个补偿数据中均保存了预设灰阶部分的数据。这样就可以减少存储器中补偿数据所占用的存储空间了。
具体的，为了更好的描述本申请实施例的数据处理方式，数据处理包括：
补偿数据以相对值的方式来存储补偿数据，以UHD（3840*2160）为例，取样点数据为（481*271），如图3所示，用目标灰阶A通过CCD相机拍摄并经过MCU处理产生8bit补偿LUT（用B’来表示），即B=B’+A，其中最高位为符号位，代表数据的正负补偿，通常会取3layer拍摄，补偿数据大约为3.2Mbit数据，flash容量的数据存储方式如图4所示，1个地址存储1个补偿数据，节省了flash容量，减少了烧录读取时间，提高了工作效率，以免补偿速度造成产能损失。而在采取本实施例的方式之前，补偿LUT为10bit数据，补偿数据为4Mbit，两个地址存储一个补偿数据。
而在将第一补偿数据烧录至存储器中时，可以先对第一补偿数据压缩，进一步降低第一补偿数据占用的存储空间。而压缩的方式可以是：获取显示装置的DeMura表（第一补偿数据表），基于DeMura表按相邻4行为一提取周期提取补偿数据；将提取的补偿数据按序进行排列以得到压缩DeMura表；将压缩DeMura表存储到存储器中；其中，按提取周期从DeMura表中提取补偿数据的步骤包括：提取第一行奇数列的补偿数据；提取第三行偶数列的补偿数据且提取第三行中第一列的补偿数据。通过压缩的方式，进一步降低了占用的空间，节省了成本。
本实施例通过采用预设灰阶来拍摄图像数据，根据拍摄的图像数据，根据图像数据来确定显示缺陷的补偿数据，而补偿数据的部分只有一部分保存在存储器中，其他部分以预设灰阶的数据的形式体现，不用每个补偿数据均保存全部的数据，减少了补偿数据占用的存储空间，缩小了需求的存储器的要求，节省了存储器的成本，进而提高了时序控制器的运行效率。
而在一实施例中，参考图5，所述根据所述第一补偿数据和预设灰阶的数据生成显示缺陷的补偿数据的步骤包括：
步骤S21，在所述补偿数据为灰阶补偿数据时，根据所述第一补偿数据和所述预设灰阶的灰阶数据生成显示缺陷的灰阶补偿数据；
步骤S22，在所述补偿数据为色差补偿数据时，根据所述第一补偿数据和所述预设灰阶的色度数据生成显示缺陷的色差补偿数据。
DeMura的数据包括灰阶数据和/或色差数据，而在只考虑灰阶数据时，采集的预设灰阶的数据就是灰阶数据，在所述补偿数据为灰阶补偿数据时，根据所述第一补偿数据和所述预设灰阶的灰阶数据生成显示缺陷的灰阶补偿数据；而在为色差补偿数据时，需要采集色度数据，除了灰阶之外，还需要采集色度数据，预设灰阶的数据包括灰阶数据和色度数据，根据所述第一补偿数据和所述预设灰阶的色度数据生成显示缺陷的色差补偿数据。
通过对灰阶和色差均考虑进行补偿，使得画面的补偿更加合理，且通过本实施例的数据处理方式，部分占用存储空间，在提高画面质量的同时，降低了存储空间占用，节省了成本。
而在一实施例中，参考图6，所述根据所述图像数据确定显示缺陷的第一补偿数据的步骤包括：
步骤S11，在所述预设灰阶包括多个灰阶数据时，拍摄的图像为多个图像数据；
步骤S12，根据所述多个图像数据分别确定多个显示缺陷的第二补偿数据；
步骤S13，根据多个第二补偿数据和预设计算方式计算显示缺陷的第一补偿数据。
在本实施例中，在预设灰阶为多个时，拍摄的图像会多个灰阶的图像，每个拍摄的图像对应有不同的显示缺陷的第二补偿数据，而根据灰阶采取的不同，根据对应的计算方式来计算得到最终的第一补偿数据，而计算方式可以是采取平均值的方式或者权重的方式来计算得到。
可选地，一实施例中，只考虑亮度补偿时，只需要检测灰阶画面，而且由于不同灰阶时呈现的Mura不同，一般会检测高中低灰阶的Mura，最后Demura数据平均，当然具体的设定根据自己的实际需求进行选择。
本实施例通过灰阶的不同，来拍摄不同的图像数据，进而得到不同的补偿数据，通过不同的补偿数据最终确定需要给DeMura的补偿数据，在减少占用存储空间的同时，提高画面显示效果。
在本申请一实施例中，参考图7，所述根据所述图像数据确定显示缺陷的第一补偿数据的步骤包括：
步骤S31，获取显示缺陷的补偿精度；
步骤S32，根据所述补偿精度和所述图像数据确定显示缺陷的第一补偿数据。
在本实施例中，每个产品的需求不同，会影响到补偿精度，产品需求不同，补偿精度不同，有的产品需要90%的良率，而有的产品需要80%的良率，良率不同，对应的补偿精度就不同，修复程度也不同。在确定补偿数据时，需要先确定补偿精度，获取显示缺陷的补偿精度；在确定补偿精度后，根据所述补偿精度和所述图像数据确定显示缺陷的第一补偿数据。图像数据不同和补偿精度不同会影响第一补偿数据，提前设置对应关系，在确定了补偿精度和图像数据后，根据对应关系确定第一补偿数据，完成画面的补偿。
本实施例通过补偿精度不同，适应不同产品的需求，保证产品质量同时，降低存储器的占用，节省成本。
可以理解的是，DeMura补偿显示装置画面的过程包括：使用高分辨率和高精度的CCD照相机拍摄画面。根据相机采集数据分析pixel颜色分布特征，并根据相关算法识别出Mura。根据mura数据及相应的Demura补偿算法产生Demura数据。将Demura数据烧录到Flash
ROM中，重新拍摄补偿后画面，确认Mura已消除。检测画面。而本申请的关键在于计算DeMura数据的部分，采取部分计算的方式，而不是全部都是补偿数据，将灰阶对应的数据不存储在存储器中，无需每个补偿数据均存储补偿数据，减少占用空间，降低成本。
此外，本申请实施例还提出一种显示装置，所述显示装置包括显示面板和与显示面板连接的时序控制器，所述时序控制器中加载有数据处理控制装置，所述显示面板在所述时序控制器的控制下完成显示操作，而时序控制器中存储的数据的处理方式以上述实施例中的数据处理方法完成，该数据处理方法加载于数据压缩装置，供时序控制器调用和启动完成数据的处理，进而更好的完成数据处理以及时序的控制效率。所述显示装置可以是电视、手机、pad、机台显示仪等移动或固定显示设备。本实施例的显示装置通过采用预设灰阶来拍摄图像数据，根据拍摄的图像数据，根据图像数据来确定显示缺陷的补偿数据，而补偿数据的部分只有一部分保存在存储器中，其他部分以预设灰阶的数据的形式体现，不用每个补偿数据均保存全部的数据，减少了补偿数据占用的存储空间，缩小了需求的存储器的要求，节省了存储器的成本，进而提高了时序控制器的运行效率。
此外，本申请实施例还提出一种计算机可读存储介质，计算机可读存储介质，所述计算机可读存储介质上存储有数据处理程序，所述数据处理程序被处理器执行时实现如上实施例所述的数据处理方法。
需要说明的是，在本文中，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、物品或者系统不仅包括那些要素，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、物品或者系统所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。

通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在如上所述的一个计算机可读存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本申请各个实施例所述的方法。
