LED模组校正方法、装置、LED显示屏及存储介质

技术领域
本申请涉及LED显示屏校正技术领域，特别是涉及LED模组校正方法、装置、LED显示屏及存储介质。
背景技术
一个LED(Light Emitting Diode，发光二极管)显示屏一般由多个LED模组拼接而成。LED模组还可以称为LED灯板，是组成LED显示屏的最小单元，由PCB(Printed Circuit Board，印刷电路板)灯板、灯珠、驱动芯片及驱动行管等组成。
为了保证LED显示屏的显示效果，在显示相同参数的色彩时，例如在显示纯色图像时，LED显示屏中各灯珠的亮度和色度需要保持一致。LED模组会在产线进行产线校正，确保每个LED模组中各灯珠亮度及色度的一致性，并把校正数据存储在LED模组中的Flash存储中。
LED显示屏安装使用时，LED显示屏的控制系统会从所有LED模组的Flash存储中读取校正数据，并根据各LED模组的校正数据，校正该LED模组的亮度和色度，以使LED显示屏在显示纯色图像时，LED显示屏中各灯珠的亮度和色度一致。

在LED显示屏安装使用时，或LED显示屏更换LED模组时，需要从各LED模组的Flash存储中读取校正数据，并按照校正数据校正各LED模组的色度和亮度，以提高显示效果。但是，Flash存储中的校正数据会存在损坏及丢失的情况，会导致无法获取LED模组的校正数据，影响LED模组的校正的成功率，从而影响LED显示屏的显示效果。
有鉴于此，本申请实施例提供了一种LED模组校正方法，参见图1，应用于LED显示屏，该方法包括：
S101，获取上述LED显示屏中待校正LED模组的标识，生成携带上述待校正LED模组的标识的标识信息。
本申请实施例中的LED模组校正方法可以通过校正系统实现，校正系统为任意能够实现本申请实施例的LED模组校正方法的系统。例如：
校正系统可以为一种电子设备，包括：处理器、存储器、通信接口和总线；处理器、存储器和通信接口通过总线连接并完成相互间的通信；存储器存储可执行程序代码；处理器通过读取存储器中存储的可执行程序代码来运行与可执行程序代码对应的程序，以用于执行本申请实施例的LED模组校正方法。可选的，校正系统可以为一种LED显示屏，例如图2所示，在LED显示屏安装使用时或更换LED模组时，LED显示屏执行本申请实施例的LED模组校正方法，以使各LED模组的亮度和色度一致。可选的，校正系统可以为一种客户端，例如图3所示，在LED显示屏安装使用时或更换LED模组时，客户端执行本申请实施例的LED模组校正方法，以使各LED模组的亮度和色度一致。
校正系统还可以为一种应用程序，用于在运行时执行本申请实施例的LED模组校正方法。
校正系统还可以为一种存储介质，用于存储可执行代码，可执行代码用于执行本申请实施例的LED模组校正方法。
在LED显示屏安装使用时，或更换LED显示屏中的LED模组时，需要 对LED模组的色度和亮度进行校正，具体的，为校正LED模组中各灯珠的色度和亮度。待校正LED模组可以根据实际情况进行设定，例如，在LED显示屏安装使用时，LED显示屏中各LED模组均为待校正LED模组；在更换LED显示屏中的LED模组时，新更换的LED模组为待校正LED模组。待校正LED模组也可以自定义设定，此处不再赘述。
校正系统获取LED显示屏中待校正LED模组的标识，其中，LED模组的标识能够唯一识别LED模组。校正系统生成携带待校正LED模组的标识的标识信息。
S102，向服务器发送上述标识信息。
校正系统向服务器发送标识信息，以使服务器在接收到标识信息后，根据标识信息中待校正LED模组的标识，读取该待校正LED模组的校正数据，并向LED显示屏发送该待校正LED模组的校正数据。
S103，获取由上述服务器根据上述标识信息返回的上述待校正LED模组的校正数据。
校正系统获取待校正LED模组的校正数据。
S104，按照上述待校正LED模组的校正数据，校正上述待校正LED模组的亮度和色度。
校正系统按照待校正LED模组的校正数据，校正待校正LED模组的亮度和色度，具体的，为校正待校正LED模组中各灯珠的亮度和色度。
在本申请实施例中，向服务器发送LED模组的标识，以获取待校正LED模组的校正数据，并对LED模组的色度和亮度进行校正，可以防止因LED模组的Flash存储中校正数据的丢失，而造成LED模组校正失败的情况，能够增加LED模组的校正的成功率，从而提高LED显示屏的显示效果。
可选的，本申请实施例的LED模组校正方法还包括：
保持记录上述LED显示屏中各LED模组的历史工作时长。
在LED显示屏使用的过程中，校正系统会记录每个LED模组的历史工作 时长，即记录每个LED模组的累计显示时间。校正系统可以周期性的记录、更新各LED模组的历史工作时长，也可以在每次LED显示屏关机时记录、更新各LED模组的历史工作时长。各LED模组的历史工作时长可以记录在本地指定位置，也可以上传到服务器中，以使服务器记录各LED模组的历史工作时长。可选的，在上述保持记录上述LED显示屏中各LED模组的历史工作时长之后，本申请实施例的LED模组校正方法还包括：周期性向上述服务器发送上述LED显示屏中各LED模组的历史工作时长，以使上述服务器记录各历史工作时长。
校正系统可以按照预设的计时周期向服务器发送LED显示屏中各LED模组的工作时长数据，例如，在计时周期为1小时时，对于LED模组A，LED模组A每工作1小时，校正系统便向服务器发送表征LED模组A的历史工作时长增加1小时的信息，以使服务器在接收到该消息后，在LED模组A现有的历史工作时长的基础上增加1小时。此处1小时仅为举例，计时周期可以根据实际情况进行设定，例如设置为5分钟、10分钟、30分钟或2小时等。
相应的，在上述按照上述待校正LED模组的校正数据，校正上述待校正LED模组之后，本申请实施例的LED模组校正方法还包括：
步骤一，获取上述LED显示屏中各LED模组的历史工作时长。
校正系统获取LED显示屏中各LED模组的历史工作时长，例如，校正系统从本地存储中获取各LED模组的历史工作时长，或校正系统从服务器中获取各LED模组的历史工作时长。校正系统向服务器发送时长查询消息，时长查询消息中包含各LED模组的标识。服务器接收到时长查询消息后，按照时长查询消息中LED模组的标识，获取相应的LED模组的历史工作时长，并返回LED模组的历史工作时长，校正系统获取各历史工作时长。
步骤二，根据各上述历史工作时长，确定上述LED显示屏的亮度衰减率。
随着LED显示器使用时间的增加，LED显示器中各LED模组的灯珠的亮度会逐渐衰减。校正系统可以根据各LED模组的历史工作时长，按照预设的LED亮度衰减算法，利用预设的亮度衰减曲线或亮度衰减函数，分别确定每个LED模组的亮度衰减率，并将最大的亮度衰减率作为LED显示屏的亮度 衰减率。其中，预设的亮度衰减曲线/亮度衰减函数表示LED模组的工作时长与亮度衰减率的对应关系。一般情况下，认为相同材料的LED模组的亮度衰减率相同，因此也可以在各LED模组的历史工作时长中，确定最长的历史工作时长，将该最长的历史工作时长的LED模组的亮度衰减率作为LED显示屏的亮度衰减率。亮度衰减率是亮度衰减的百分比，例如对于亮度为1000坎德拉/平方米的LED模组，其亮度衰减为900坎德拉/平方米时，该LED模组的亮度衰减率为10％，例如对于亮度为1200坎德拉/平方米的LED模组，其亮度衰减为900坎德拉/平方米时，该LED模组的亮度衰减率为25％等。
步骤三，按照上述LED显示屏的亮度衰减率，校正上述待校正LED模组的亮度。
根据LED显示屏的亮度衰减率，将待校正LED模组的亮度调整为与LED显示屏中其他LED模组的亮度相同。例如，在待校正LED模组为未使用过的LED模组时，按照LED显示屏的亮度衰减率，降低该LED模组的亮度。例如，LED显示屏的亮度衰减率为20％，则将待校正LED模组的亮度调整为标准亮度的80％，其中，标准亮度为通过校正数据校正后的待校正LED模组的亮度，例如，为LED显示屏出厂时，通过校正数据校正后的LED显示屏中各LED模组的统一亮度。
在本申请实施例中，确定LED显示屏的亮度衰减率，并按照LED显示屏的亮度衰减率，削减待校正LED模组的亮度，能够提高LED显示屏的显示效果。
可选的，上述根据各上述历史工作时长，确定上述LED显示屏的亮度衰减率，包括：
步骤一，在上述LED显示屏中，选取符合预设基准规则的LED模组，作为基准LED模组。
预设基准规则可以根据实际情况进行设定，例如，选取历史工作时长最长、亮度衰减率最大或亮度最低的LED模组，作为基准LED模组；或以单位时间为步长，划分多个时段，按照历史工作时长，将LED模组划分到对应的时段中，在LED模组数量最多的时段中，选取一个LED模组作为基准LED 模组等。
步骤二，按照预设的亮度衰减曲线，确定上述基准LED的历史工作时长对应的亮度衰减率，作为上述LED显示屏的亮度衰减率。
一般情况下，在LED显示屏中，历史工作时长最长的LED模组的亮度衰减最严重，因此可以选取历史工作时长最长的LED模组，作为基准LED模组。将基准LED模组的亮度衰减率，作为LED显示屏的亮度衰减率，能够保证LED显示屏中各LED模组的亮度可以调节一致。预设的亮度衰减曲线为实验测得的灯珠亮度与使用时间的对应关系，例如，一种LED模组灯珠亮度与历史工作时长的曲线图，可以如图4所示，其中，横轴代表LED模组的使用时间，单位为小时；纵轴代表LED模组的亮度，单位为坎德拉每平方米。此处图4仅为示意，不同灯珠材质的LED模组亮度与使用时间的对应关系不同，可以利用实际LED模组测量得到。校正系统按照亮度衰减曲线，确定基准LED的历史工作时长对应的亮度衰减率。
在本申请实施例中，选取历史工作时长最长的LED模组，作为基准LED模组，将基准LED模组的亮度衰减率，作为LED显示屏的亮度衰减率，能够保证LED显示屏中各LED模组的亮度可以调节一致。
可选的，在上述按照预设的亮度衰减曲线，确定上述基准LED的历史工作时长对应的亮度衰减率，作为上述LED显示屏的亮度衰减率之后，上述方法还包括：
步骤一，在所述LED显示屏除所述基准LED模组及所述待校正LED模组外的其他LED模组中，选取亮度与所述基准LED模组亮度不同的LED模组，作为目标LED模组。
例如，可以根据各LED模组的历史工作时长来确定各LED模组的亮度，以确定目标LED模组，可以根据各LED模组的历史工作时长及各LED模组的亮度衰减曲线，分别确定各LED模组的亮度衰减率；并根据各LED模组的亮度衰减率，分别确定各LED模组当前的亮度；按照各LED模组当前的亮度，选取亮度与基准LED模组亮度不同的LED模组，得到目标LED模组。或通过光学仪器检测各LED模组的亮度，以确定目标LED模组。或将用户人工选 取的亮度不同的LED模组，作为目标LED模组等。在各LED模组的灯珠材料均相同时，历史工作时长相同LED模组的亮度衰减率也相同，其亮度也就相同，因此可以将历史工作时长与基准LED模组历史工作时长不同的LED模组作为目标LED模组。
步骤二，按照所述LED显示屏的亮度衰减率，校正所述目标LED模组的亮度。
根据LED显示屏的亮度衰减率，将LED显示屏中各目标LED模组的亮度调整为与基准LED模组的亮度相同，从而实现LED显示屏中各LED模组的亮度相同。在一些情况下，例如LED显示屏长期使用且未校正的情况下，校正系统还可以根据LED显示屏的亮度衰减率，校正该LED显示屏中的亮度与基准LED模组亮度不同LED模组，以保证各LED显示屏的亮度相同，从而增强LED显示屏的显示效果。

针对每个LED模组，服务器根据该LED模组的工作时长数据，记录该LED模组的历史工作时长。例如，针对LED模组A，其工作时长数据表征LED模组A历史工作时长为200小时，则服务器记录LED模组A的历史工作时长为200小时；或针对LED模组A，工作时长数据表征LED模组A工作时长增量0.25小时，则服务器将LED模组A的历史工作时长增加0.25小时。
