Description

一种LED显示屏的数据存储方法及相关装置 技术领域
本申请涉及显示屏控制技术领域，尤其涉及一种发光二极管(light emitting diode，LED)显示屏的数据存储方法及相关装置。
背景技术
随着现代工业技术的快速发展，LED显示屏逐渐在人们生活以及工业生产过程中得到了普遍的应用。LED显示屏不但制造简单，可在各个不同的环境下保持正常的工作，而且LED显示屏具有分辨率高、可视范围广、可视距离远、面积大等特点。LED显示屏通常应用于户外广告、商业显示、舞台租赁、数据可视化等领域。在LED显示屏控制系统中，LED显示屏是一种由一个个小的LED模组或LED箱体拼接而成的平板显示器，用于显示文字、图像、视频等各种信息。而每个LED箱体包括接收卡和电连接至接收卡的多个LED灯板，接收卡用于驱动LED灯板显示。有些LED显示屏的LED箱体还会配置转接卡(Hub卡)，以将多个LED灯板连接至接收卡，此处的转接卡起到接口扩展、信号转接的作用。由于LED显示屏可广泛应用于如交通讯号灯、文艺演出、新闻发布等多种场景，人们对LED显示屏的显示需求也越来越高。在LED显示屏的上述应用场景中，只要有个别LED发生故障，就可能影响LED显示屏整体的显示效果，故需要时常维护LED。而由于LED显示屏中的LED固有的半导体特性，不同的LED具有不同的发光特性以及衰减特性，故有必要通过亮色度校正来实现LED显示屏的均匀显示。因此，亮色度校正数据的存储和使用至关重要。
目前，较为常用的存储方法是将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储和使用。其中，LED显示驱动电路电连接多路分配器并用于根据多路分配器分配的LED显示用信号来驱动多个LED，存储器电路电连接多路分配器并用于根据多路分配器分配的数据读/写用信号进行数据读/写操作，多路分配器设置有信号分配控制端，并根据信号分配控制端的输入信号状态来决定待分配的信号为LED显示用信号还是数据读/写用信号。
但是，上述存储方法需要增加多路分配器，增大了LED显示屏控制电路的复杂性；并且，一旦LED灯板上的存储器存储的校正数据因故障丢失，无法自行恢复，给LED显示屏的亮色度校正工作带来极大困扰。
发明内容
本申请实施例公开了一种LED显示屏的数据存储方法及相关装置，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据；通过使用接收卡存储的亮色度校正数据进行亮色度校正，或使用上位机中存储的亮色度校正数据进行亮色度校正，或通过上位机访问服务器，并使用服务器中存储的亮色度校正数据进行亮色度校正；简化了LED显示屏控制电路，并且，当校正数据因故障丢失时，接收卡还可以从上位机获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。
第一方面，本申请实施例公开了一种LED显示屏的数据存储方法，包括：
获取灯板的第一信息和接收卡的第二信息；上述第一信息包括存储于上述灯板的灯板序列号，上述第二信息包括存储于上述接收卡的灯板序列号；
在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度校正；
在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。
在本申请实施例中，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据。首先获取存储于灯板的灯板序列号以及存储于接收卡的灯板序列号，然后将从二者获取到的灯板序列号进行比对，根据比对结果确定用于对LED显示屏进行亮色度校正的校正数据，上述确定的校正数据可能来源于接收卡或上位机或服务器的存储器中。具体为在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度校正；在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。本申请实施例通过使用接收卡存储的亮色度校正数据进行亮色度校正，或使用上位机中存储的亮色度校正数据进行亮色度校正，或通过上位机访问服务器，并使用服务器中存储的亮色度校正数据进行亮色度校正。相比于目前将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储方法，本申请实施例中的方法大大简化了LED显示屏控制电路，降低了电路设计复杂度，节约了硬件成本；并且，当校正数据因故障丢失时，接收卡还可以从上位机获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。
在第一方面的一种可能的实施方式中，将存储于上位机或服务器中的亮色度校正系数作为校正数据，包括：
若在上述上位机中查询到亮色度校正系数，将存储于上述上位机中的亮色度校正系数作为上述校正数据；
若未在上述上位机中查询到亮色度校正系数，将存储于上述服务器中的亮色度校正系数作为上述校正数据。
在本申请实施例中，对第一信息与第二信息不同的情况下，如何确定校正数据进行了说明，即在存储于灯板的灯板序列号和存储于接收卡的灯板序列号不同的情况下，不使用接收卡中存储的亮色度校正系数作为校正数据对LED显示屏进行亮色度校正，而是将存储于上述上位机中的亮色度校正系数确定为校正数据，用于对LED显示屏进行亮色度校正。因为灯板序列号可作为识别灯板的唯一标识符，且灯板序列号与相应的亮色度校正系数为一一对应的关系，即一个灯板序列号只有一个唯一的亮色度校正系数与之对应。当存储于灯板的灯板序列号和存储于接收卡的灯板序列号不同时，表明接收卡出现了某种故障导致灯板序列号数据丢失或错乱，此时，存储在接收卡中的与上述灯板序列号相对应的亮色度校正系数也是不可信的。故不使用接收卡中存储的亮色度校正系数作为校正数据，而是将存储于上述上位机中的亮色度校正系数确定为校正数据，使后续的LED显示屏的亮色度校正工作能够正常有效进行，提高了校正效率。若因上位机故障等问题导致数据丢失或错乱， 未在上位机中查询到与存储于灯板的灯板序列号相对应的亮色度校正系数，此时将进一步通过上位机访问服务器，将服务器数据库中的与存储于灯板的灯板序列号相对应的亮色度校正系数作为校正数据，用于对LED显示屏进行亮色度校正。如此，即使接收卡和上位机同时出现了某种故障导致灯板序列号数据和相应的亮色度校正系数丢失或错乱等问题，还能通过访问服务器，将服务器数据库中存储的亮色度校正系数作为有效的校正数据，使后续的LED显示屏的亮色度校正工作能够正常有效进行，提高了校正效率。

第二方面，本申请实施例公开了一种LED显示屏的数据存储装置，包括：
获取单元，用于获取灯板的第一信息和接收卡的第二信息；上述第一信息包括存储于上述灯板的灯板序列号，上述第二信息包括存储于上述接收卡的灯板序列号；
确定单元，用于在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度 校正；
上述确定单元，还用于在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。
在本申请实施例中，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据。首先获取存储于灯板的灯板序列号以及存储于接收卡的灯板序列号，然后将从二者获取到的灯板序列号进行比对，根据比对结果确定用于对LED显示屏进行亮色度校正的校正数据，上述确定的校正数据可能来源于接收卡或上位机或服务器的存储器中。具体为在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度校正；在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。本申请实施例通过使用接收卡存储的亮色度校正数据进行亮色度校正，或使用上位机中存储的亮色度校正数据进行亮色度校正，或通过上位机访问服务器，并使用服务器中存储的亮色度校正数据进行亮色度校正。相比于目前将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储方法，本申请实施例中的方法大大简化了LED显示屏控制电路，降低了电路设计复杂度，节约了硬件成本；并且，当校正数据因故障丢失时，接收卡还可以从上位机获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。

本申请实施例提供了一种LED显示屏的数据存储方法，为了更清楚地描述本申请的方案，下面先介绍一些与LED显示屏相关的知识。
LED显示屏箱体：LED显示屏箱体简单地讲就是由若干个可组合拼接的显示单元(单元显示板或单元显示箱体)构成的屏体。为满足不同环境，再加上一套适当的控制器(主控板或控制系统)，所以多种规格的显示板(或单元箱体)配合不同控制技术的控制器就可以组成许多种LED显示屏，满足不同显示需求。LED显示屏模组：LED显示屏模组(灯板)是组成 LED显示屏成品的主要部件之一，其主要由LED灯、印制电路板(printed circuit board，PCB)、驱动芯片、电阻、电容和塑料套件组成。
下面结合本申请实施例中的附图对本申请实施例进行描述。
请参阅图1，图1为本申请实施例提供的一种LED显示屏亮色度校正的架构示意图。如图1所示，该架构图包括了LED显示屏、控制卡、LED屏控制计算机、电源以及开关。其中，电源用于给控制卡和LED显示屏供电，用户可通过开关控制电源的开启与关闭，从而控制控制卡和LED显示屏的启动。LED屏控制计算机会输出视频信号给LED显示屏，该视频信号用于通过LED显示屏中的LED模组或灯板呈现相应的图像信息。LED屏控制计算机与控制卡网络连接，二者之间可通过高清多媒体接口(high definition multimedia interface，HDMI)或数字视频接口(digital visual interface，DVI)进行数据传输。控制卡内部结构主要包括微控制单元(microcontroller unit，MCU)和现场可编程逻辑门阵列(field programmable gate array，FPGA)。其中，MCU用于处理测试参数和监控整个LED显示屏箱体的工作情况，FPGA用于接收LED屏控制计算机发送的视频信号，并驱动LED显示屏的灯板显示与该视频信号相对应的图像。控制卡在获得电源的供电启动后，可以把LED屏控制计算机的视频信号转发给LED显示屏的接收卡，控制卡转发的视频信号为并行视频信号。LED显示屏在获得电源的供电后可启动LED显示屏中的驱动模块，进而启动LED显示屏中的LED模组或灯板，LED显示屏中的驱动模块接收到控制卡发送的并行视频信号后，将之转换为LED显示屏可识别的串行视频信号，并将该串行视频信号传输至LED显示屏，LED显示屏接收到该串行视频信号后，点亮LED灯珠并显示与该串行视频信号相对应的图像信息。
可选的，该架构图还可以包括电源管理模块以及与之对应的开关，其中，控制卡和LED显示屏均分别包含有为自身供电的电源。用户可通过开关控制电源管理模块的控制信号发送，该控制信号可用于控制上述控制卡和LED显示屏自身供电的电源的开启和关闭，从而达到间接控制控制卡和LED显示屏启动的效果。具体的，电源管理模块发送的控制信号还可以用于控制上述控制卡和LED显示屏自身供电的电源的开启时序，即可控制控制卡和LED显示屏以不同的时序启动。
基于上述图1提供的LED显示屏亮色度校正的架构，LED显示屏中只要有个别LED发生故障，就可能影响LED显示屏整体的显示效果，故需要时常维护LED。而由于LED显示屏中的LED固有的半导体特性，不同的LED具有不同的发光特性以及衰减特性，故有必要通过亮色度校正来实现LED显示屏的均匀显示。因此，亮色度校正数据的存储和使用至关重要。目前，较为常用的存储方法是将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储和使用。其中，LED显示驱动电路电连接多路分配器并用于根据多路分配器分配的LED显示用信号来驱动多个LED，存储器电路电连接多路分配器并用于根据多路分配器分配的数据读/写用信号进行数据读/写操作，多路分配器设置有信号分配控制端，并根据信号分配控制端的输入信号状态来决定待分配的信号为LED显示用信号还是数据读/写用信号。但是，上述存储方法需要增加多路分配器，增大了LED显示屏控制电路的复杂性；并且，一旦LED灯板上的存储器存储的校正数据因故障丢失，无法自行恢复，给LED显示屏的亮色度校正工作带 来极大困扰。
针对上述LED显示屏的数据存储中存在的问题，本申请实施例提供了一种LED显示屏的数据存储方法，该方法能有效解决上述LED灯板上的存储器存储的校正数据丢失，无法自行恢复，从而无法进行亮色度校正的问题。
请参阅图2，图2为本申请实施例提供的一种LED显示屏的数据存储方法的流程示意图，该方法包括但不限于如下步骤：
步骤201：获取灯板的第一信息和接收卡的第二信息。
接收卡获取灯板的第一信息和接收卡的第二信息，本申请实施例中的接收卡为LED显示屏的内部元器件，主要包括MCU和存储器，其中，MCU用于处理测试参数和监控整个LED显示屏箱体的工作情况，存储器用于存储灯板的相关数据，包括灯板序列号、厂商信息、灯板型号、生产日期、行扫数、板载LED点数等。
上述第一信息包括存储于灯板的灯板序列号，可选的，还可以包括灯板的厂商信息、灯板型号、生产日期、行扫数、板载LED点数等和灯板相关的信息，上述第二信息包括存储于接收卡的灯板序列号，以及包括和上述第一信息相同类目项的信息。其中，接收卡用于接收视频信号，并驱动灯板显示，灯板是LED显示屏的显示单元。灯板序列号可作为识别灯板的唯一标识符以对不同的灯板进行区分，且灯板序列号与相应的亮色度校正系数为一一对应的关系，即一个灯板序列号只有一个唯一的亮色度校正系数与之对应。上述灯板序列号和与之对应的亮色度校正系数可存储于相应灯板的存储器中，也可以同时存储于接收卡的存储器中，该存储器可采用带电可擦可编程只读存储器(electrically erasable programmable read only memory，EEPROM)，该存储器具有掉电后数据不丢失的特性，可以在电脑上或专用设备上擦除已有信息，重新编程，可即插即用，存储效率高。
需要注意的是，上述存储于灯板的第一信息和存储于接收卡的第二信息在正常情况下是相同的，因为同一灯板的灯板序列号是不变的数据，但在实际情况中，接收卡可能会因故障导致接收卡的存储器中存储的数据丢失或错乱，所以上述第一信息和上述第二信息也可能存在不相同的情况，故需要对他们进行比对。并且，由于LED显示屏中的LED固有的半导体特性，不同的LED具有不同的发光特性以及衰减特性，也会受到工作温度的影响导致显示问题，故LED灯板对应的亮色度校正数据可能也存在改变的情况，该情况也会导致存储于灯板的第一信息和存储于接收卡的第二信息不相同。
此外，对于同一灯板的灯板序列号，与之对应的亮色度校正系数，以及灯板的厂商信息、灯板型号、生产日期、行扫数、板载LED点数等和灯板相关的信息，还可以同时存储于上位机的本地数据库以及可与上位机通信的服务器数据库中。
步骤202：在上述第一信息和第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据。
接收卡获取灯板的第一信息和接收卡的第二信息后，将上述第一信息和上述第二信息进行比对，并根据比对结果确定校正数据，用于对LED显示屏进行亮色度校正，上述确定的校正数据可能来源于接收卡或上位机或服务器的存储器中。
具体的，接收卡上电后，在需要对LED显示屏的某块灯板进行亮色度校正的情况下，获取存储于该灯板的灯板序列号以及存储于接收卡的灯板序列号，并将二者进行比对。
其中，一种可能的比对结果为，如果上述二者的灯板序列号不一致，则表明接收卡出现了某种故障导致灯板序列号数据丢失或错乱，此时，存储在接收卡中的与上述灯板序列号相对应的亮色度校正系数也是不可信的，故不能使用接收卡中存储的亮色度校正系数作为校正数据，而是通知上位机，由上位机查询本地数据库中的灯板序列号和与之对应的亮色度校正系数，若查询到相应结果，则将存储于上位机中的亮色度校正系数作为校正数据，用于后续的LED显示屏亮色度校正工作中，使得在接收卡中的数据丢失的情况下，依然能使后续的LED显示屏的亮色度校正工作正常有效进行，提高了校正效率。此外，在将存储于上位机中的亮色度校正系数作为校正数据之前，还将上述第一信息和存储于上述上位机中的亮色度校正系数存储于接收卡中，其中，第一信息用于替换接收卡的第二信息，上述上位机中的亮色度校正系数用于替换接收卡中的亮色度校正系数，如此可以使接收卡中存储的灯板序列号和与之对应的亮色度校正系数保持有效，使得在后续的LED显示屏亮色度校正过程中，可省去访问上位机的过程，直接用于下一次LED显示屏的亮色度校正，提高校正效率。
另一种可能的比对结果为，如果上述二者的灯板序列号不一致，则表明接收卡出现了某种故障导致灯板序列号数据丢失或错乱，此时，存储在接收卡中的与上述灯板序列号相对应的亮色度校正系数也是不可信的，应通知上位机，由上位机查询本地数据库中的灯板序列号和与之对应的亮色度校正系数，若未在上位机的本地数据库中查询到相应结果，此时将进一步通过上位机访问服务器，将服务器数据库中的与存储于灯板的灯板序列号相对应的亮色度校正系数作为校正数据，用于对LED显示屏进行亮色度校正，使得在接收卡和上位机同时出现某种故障导致灯板序列号数据和相应的亮色度校正系数丢失或错乱等问题的情况下，还能使后续的LED显示屏的亮色度校正工作正常有效进行，提高了校正效率。此外，在将服务器数据库中的与存储于灯板的灯板序列号相对应的亮色度校正系数作为校正数据之前，还将上述第一信息和存储于上述服务器数据库中的亮色度校正系数存储于接收卡和上位机中，其中，第一信息用于替换接收卡的第二信息和上位机的相关信息，上述服务器数据库中的亮色度校正系数用于替换接收卡中的亮色度校正系数和上位机中的亮色度校正系数，如此可以使接收卡和上位机中存储的灯板序列号和与之对应的亮色度校正系数保持有效，使得在后续的LED显示屏亮色度校正过程中，可省去访问上位机和服务器的过程，直接将接收卡中存储的数据用于下一次LED显示屏的亮色度校正，提高校正效率。
步骤203：在上述第一信息和第二信息相同的情况下，将存储于接收卡中的亮色度校正系数作为校正数据。
接收卡上电后，在需要对LED显示屏的某块灯板进行亮色度校正的情况下，获取存储于该灯板的灯板序列号以及存储于接收卡的灯板序列号，并将二者进行比对。
还有另一种可能的比对结果为，如果二者的灯板序列号一致，则表明接收卡处于正常状态，其中存储的灯板序列号和相对应的亮色度校正系数等数据是有效的，可直接用于后续的LED显示屏亮色度校正工作中，省去了访问上位机和服务器的步骤，提高了校正效率。
本申请实施例中的LED显示屏的数据存储方法，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据，通过使用接收卡存储的亮色度校正数据、或上位机中存储的亮色度校正数据、或服务器中存储的亮色度校正数据进 行亮色度校正。相比于目前将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储方法，本申请实施例中的数据存储方法大大简化了LED显示屏控制电路，降低了电路设计复杂度，节约了硬件成本；并且，当校正数据因故障丢失时，接收卡还可以从上位机或服务器获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。
请参阅图3，图3为本申请实施例提供的另一种LED显示屏的数据存储方法的流程示意图。图3可以理解为是上述图2提供的LED显示屏的数据存储方法的实现过程步骤的细化，如图3所示，接收卡上电后读取灯板序列号，该灯板序列号是存储于灯板内的存储器中，接收卡再读取板载存储器上存储的灯板序列号，然后比对两次获取到的灯板序列号是否一致，如果是，则接收卡使用校正数据，用于后续LED显示屏的亮色度校正；如果比对两次获取到的灯板序列号不一致，则通知上位机，由上位机查询本地数据库中是否包含灯板序列号与存储于灯板内的灯板序列号一致，若查询到该灯板序列号，则将该灯板序列号对应的亮色度校正系数确定为校正数据并发送给接收卡，用于后续LED显示屏的亮色度校正；如果未在上位机的本地数据库中查询到该灯板序列号，则由上位机查询服务器数据库中是否包含灯板序列号与存储于灯板内的灯板序列号一致，若查询到该灯板序列号，则将该灯板序列号对应的亮色度校正系数确定为校正数据并发送给接收卡，用于后续LED显示屏的亮色度校正；若本次服务器数据库的查询未查询到，则继续查询操作，直至查询到上述灯板序列号。
另一方面，请参阅图4a，图4a为本申请实施例提供的一种LED显示屏模组的架构示意图。如图4a所示，其内部主要包括了电源、电源管理模块、驱动模块和显示模块。其中，电源用于将交流电转换为直流电供其他功能模块(如电源管理模块、驱动模块、显示模块)使用，电源管理模块用于对电源进行管理，实现分时上电功能，即控制不同的功能模块(如驱动模块、显示模块)的上电时序，驱动模块用于将控制卡发送的并行视频信号转换为显示模块可识别的串行视频信号，显示模块用于接收到串行视频信号后显示与该串行视频信号对应的图像信息，该显示模块可以为一个或若干个LED灯珠。由多个上述图4a中的LED显示屏模组构成的LED显示屏箱体，其内部电路可参阅图4b。图4b为本申请实施例提供的一种LED显示屏箱体的电路示意图，如图4b所示，该电路由接收卡、HUB板以及多个灯板(LED显示屏模组)构成。接收卡主要包括MCU和存储器，其中，MCU用于处理测试参数和监控整个LED显示屏箱体的工作情况，存储器用于存储灯板的相关数据，包括灯板序列号、厂商信息、灯板型号、生产日期、行扫数、板载LED点数等。HUB板将多个LED灯板连接至接收卡，此处的HUB板起到接口扩展、信号和电源转接的作用。灯板1、灯板2、……、灯板N是LED显示屏的显示单元，用于显示文字、图像、视频等各种信息，其中，每个灯板都包括一个EEPROM，其功能和接收卡中的存储器类似，用于存储灯板的相关数据，此处选用的灯板拥有A0、A1、A2三个地址脚，也可以设置成8个地址脚。接收卡通过集成电路总线(Inter-Integrated Circuit，IIC)接口，可以同时读写8块灯板的校正数据。由于EEPROM的读写接口是IIC总线，所以多块灯板可以作为从设备挂在一根总线上。接收卡读写灯板的EEPROM时，只需要两个上拉电阻R1、R2即可完成读写工作，大大简化了LED显示屏控制电路，降低了电路设计复杂度，节约了硬件成本。且灯板不再存储校正数据，校 正数据直接存储在接收卡的存储器、上位机以及服务器中，当接收卡中的校正数据丢失时，接收卡还可以从上位机和服务器中获取有效的校正数据，提高LED显示屏的亮色度校正工作的效率。
上述详细阐述了本申请实施例的方法，下面提供本申请实施例的装置。
请参阅图5，图5为本申请实施例提供的一种LED显示屏的数据存储装置的结构示意图。该LED显示屏的数据存储装置50可以包括获取单元501、确定单元502以及存储单元503，其中，各个单元的描述如下：
获取单元501，用于获取灯板的第一信息和接收卡的第二信息；上述第一信息包括存储于上述灯板的灯板序列号，上述第二信息包括存储于上述接收卡的灯板序列号；
确定单元502，用于在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度校正；
上述确定单元502，还用于在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。
在本申请实施例中，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据。首先获取存储于灯板的灯板序列号以及存储于接收卡的灯板序列号，然后将从二者获取到的灯板序列号进行比对，根据比对结果确定用于对LED显示屏进行亮色度校正的校正数据，上述确定的校正数据可能来源于接收卡或上位机或服务器的存储器中。具体为在上述第一信息和上述第二信息不同的情况下，将存储于上位机或服务器中的亮色度校正系数作为校正数据，上述校正数据用于对上述LED显示屏进行亮色度校正；在上述第一信息和上述第二信息相同的情况下，将存储于上述接收卡中的亮色度校正系数作为上述校正数据。本申请实施例通过使用接收卡存储的亮色度校正数据进行亮色度校正，或使用上位机中存储的亮色度校正数据进行亮色度校正，或通过上位机访问服务器，并使用服务器中存储的亮色度校正数据进行亮色度校正。相比于目前将亮色度校正数据直接存储在LED灯板的存储器中，通过多路分配器、LED显示驱动电路以及存储器电路来实现亮色度校正数据的存储方法，本申请实施例中的方法大大简化了LED显示屏控制电路，降低了电路设计复杂度，节约了硬件成本；并且，当校正数据因故障丢失时，接收卡还可以从上位机获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。

在本申请实施例中，对第一信息与第二信息不同的情况下，如何确定校正数据进行了说明，即在存储于灯板的灯板序列号和存储于接收卡的灯板序列号不同的情况下，不使用接收卡中存储的亮色度校正系数作为校正数据对LED显示屏进行亮色度校正，而是将存储于上述上位机中的亮色度校正系数确定为校正数据，用于对LED显示屏进行亮色度校正。因为灯板序列号可作为识别灯板的唯一标识符，且灯板序列号与相应的亮色度校正系数为 一一对应的关系，即一个灯板序列号只有一个唯一的亮色度校正系数与之对应。当存储于灯板的灯板序列号和存储于接收卡的灯板序列号不同时，表明接收卡出现了某种故障导致灯板序列号数据丢失或错乱，此时，存储在接收卡中的与上述灯板序列号相对应的亮色度校正系数也是不可信的。故不使用接收卡中存储的亮色度校正系数作为校正数据，而是将存储于上述上位机中的亮色度校正系数确定为校正数据，使后续的LED显示屏的亮色度校正工作能够正常有效进行，提高了校正效率。若因上位机故障等问题导致数据丢失或错乱，未在上位机中查询到与存储于灯板的灯板序列号相对应的亮色度校正系数，此时将进一步通过上位机访问服务器，将服务器数据库中的与存储于灯板的灯板序列号相对应的亮色度校正系数作为校正数据，用于对LED显示屏进行亮色度校正。如此，即使接收卡和上位机同时出现了某种故障导致灯板序列号数据和相应的亮色度校正系数丢失或错乱等问题，还能通过访问服务器，将服务器数据库中存储的亮色度校正系数作为有效的校正数据，使后续的LED显示屏的亮色度校正工作能够正常有效进行，提高了校正效率。
在一种可能的实施方式中，上述LED显示屏的数据存储装置50还包括：
存储单元503，用于将上述第一信息和存储于上述上位机中的亮色度校正系数存储于上述接收卡中；上述第一信息用于替换上述第二信息，上述上位机中的亮色度校正系数用于替换上述接收卡中的亮色度校正系数。

在一种可能的实施方式中，上述存储单元503，还用于将上述第一信息和存储于上述服务器中的亮色度校正系数存储于上述接收卡中；上述第一信息用于替换上述第二信息，上述服务器中的亮色度校正系数用于替换上述接收卡中的亮色度校正系数。

根据本申请实施例，图5所示的装置中的各个单元可以分别或全部合并为一个或若干个另外的单元，或者其中的某个(些)单元还可以再拆分为功能上更小的多个单元来构成， 这可以实现同样的操作，而不影响本申请的实施例的技术效果的实现。上述单元是基于逻辑功能划分的，在实际应用中，一个单元的功能也可以由多个单元来实现，或者多个单元的功能由一个单元实现。在本申请的其它实施例中，基于终端也可以包括其它单元，在实际应用中，这些功能也可以由其它单元协助实现，并且可以由多个单元协作实现。
需要说明的是，各个单元的实现还可以对应参照图2和图3所示的方法实施例的相应描述。
在图5所描述的LED显示屏的数据存储装置中，不需要在LED灯板中存储亮色度校正数据，而是在接收卡、上位机和服务器中存储亮色度校正数据；通过使用接收卡存储的亮色度校正数据、或上位机中存储的亮色度校正数据、或服务器中存储的亮色度校正数据进行亮色度校正，简化了LED显示屏控制电路；并且，当校正数据因故障丢失时，接收卡还可以从上位机获取正确的校正数据，提高LED显示屏的亮色度校正工作的效率。
