一种LED显示屏的显示控制方法及相关装置 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)显示屏的显示控制方法及相关装置。
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，需要显示屏幕菜单式调节方式(on-screen display，OSD)信息，为了能够快速准确的定位配置好每个LED模组的物理位置(图像坐标)，使每个LED模组能够显示出整体画面中它所在的位置应显示的内容，维护人员需要能够直观形象的知道LED显示屏各个模组的拼接顺序号或者模组的当前情况，才能快速、高效的完成模组连屏拼接操作。
目前，较为常用的显示OSD的显示控制方法，是通过上位机存储多张图片到外部存储器中，通过上位机发送切换命令，调用存储在外部存储器中的图片与当前画面进行叠加处理后进行显示。或者，通过上位机制作图像缓存至控制系统存储器，将图像数据作为OSD数据叠加在第一层图像上，经过LED控制器的图像处理模块再次叠加处理后得到可以输出显示的图像数据。
但是，上述显示控制方法需要提前存储多张可显示图片，显示内容不够灵活，外部存储器硬件成本较大；并且，需要对OSD数据进行二次叠加处理，处理效率低。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地描述。
本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等仅用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备等，没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元等，或可选地还包括对于这些过程、方法、产品或设备等固有的其它步骤或单元。

在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上，“至少两个(项)”是指两个或三个及三个以上，“和/或”，用于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：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”。
本申请实施例提供了一种LED显示屏的显示控制方法，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。
屏幕菜单式调节方式(OSD)：on-screen display的简称，一般是按菜单键后屏幕弹出的显示器各项调节项目信息的矩形菜单，可通过该菜单对显示器各项工作指标包括色彩、模式、几何形状等进行调整，从而达到最佳的使用状态。其一般应用于LED显示器上，在显示器的荧幕中产生一些特殊的字形或图形，让使用者得到相关讯息。常见于家用电视机或个人电脑之显示荧幕上，当使用者操作电视机换台或调整音量、画质等，电视荧幕就会显示目前状态让使用者获知，此控制芯片可在荧幕上的任何位置显示一些特殊字形与图形，成为人机界面上重要的讯息产生装置。
目前，较为常用的显示OSD的显示控制方法，是通过上位机存储多张图片到外部存储器中，通过上位机发送切换命令，调用存储在外部存储器中的图片与当前画面进行叠加处理后发送到FPGA驱动显示系统中进行显示。该方法事先需要存储多张可显示图片，显示内容不够灵活便捷，且导致外部存储管理器硬件成本增加。
或者，通过上位机制作文字显示图像缓存至控制系统存储器，将显示图像数据作为OSD数据叠加在第一层图像上，经过LED控制器的图像数据处理模块再次叠加处理后得到可以输出显示的图像数据。该方法使用的文字显示图像是事先通过上位机制作好的显示内容，以图片的形式存储在存储器中，所以操作制作过程繁琐，如果存储多张显示图片的话需要存储器的空间较大，这样导致硬件成本较高。另外该方法需要对显示图像和背景图像进行叠加后，使用LED控制器的图像数据处理模块进行二次叠加处理后生成可用的显示图像数据，这样的OSD显示处理较繁琐。
针对上述显示OSD的显示控制方法中存在的问题，本申请提供了LED显示屏基于校正数据显示OSD的一种快速、高效的使用方法，使得维护人员在维护LED显示屏时便捷、高效。
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。

步骤402：根据上述OSD提示信息指令生成OSD显示数据，该OSD显示数据的数据格式为LED显示屏的校正数据的数据格式。
LED显示屏接收OSD提示信息指令后，根据该OSD提示信息指令生成OSD显示数据。具体的，也是由LED显示屏中的各个显示模组根据该OSD提示信息生成OSD显示数据。LED显示模组接收到分发的OSD提示信息指令后，由其内部的控制系统解析该OSD提示信息指令，得到包括组成上述OSD显示数据的元素的提示信息，LED显示模组再根据该提示信息在内部存储系统存储的字库中查找，获取与提示信息对应的字库数据，最后LED显示模组内的控制系统根据获取到的字库数据，组合生成上述OSD显示数据。该OSD显示数据的数据格式为LED显示屏的校正数据的数据格式，便于后续将OSD显示数据通过校正数据通道传输至LED显示模组内的显示系统中，根据OSD显示数据和校正数据进行相应的内容显示。该生成OSD显示数据的方法，可以无需通过外部存储器提前存储大量可显示图片，而是由LED显示模组内的各个组成系统自动生成，能够节省大量的存储资源，降低存储硬件成本，且生成的OSD显示数据对应的内容更多样，提高了显示效率。
步骤403：根据上述OSD显示数据和上述校正数据进行上述LED显示屏的显示。
由上述步骤402可知，生成的OSD显示数据是以校正数据的数据格式和LED显示屏的校正数据并存的，LED显示模组可根据实际的应用场景需求而相应的显示OSD显示数据或校正数据。具体的，LED显示模组内的控制系统可向驱动显示系统发送指令，指示其选择OSD显示数据对应的内容进行显示，或者，也可以是指示其选择校正数据对应的内容进行显示，该校正数据为被OSD显示数据覆盖后的当前校正数据。本申请实施例提供的OSD显示数据的显示控制方法，无需对OSD显示数据进行二次叠加处理，大大简化了对OSD显示数据的处理逻辑，提高了OSD显示数据的处理效率。
请参阅图5，图5为本申请实施例提供的另一种LED显示屏的显示控制方法的流程示意图。图5可以理解为是上述图4提供的LED显示屏的显示控制方法的实现过程步骤的细化，由LED显示模组的控制系统接收OSD提示信息指令，该控制系统对该OSD提示信息指令解析后，得到组成OSD显示数据的元素，控制系统从FLASH存储系统中获取与上述元素相对应的字库数据，并将获取到的字库数据组合生成OSD显示数据，该OSD显示数据的数 据格式为LED显示屏的校正数据的数据格式，控制系统再将该OSD显示数据传输给FPGA驱动显示系统进行显示，FPGA驱动显示系统可根据应用场景的实际需求，选择OSD显示数据对应的内容进行显示，或者，也可以是选择校正数据对应的内容进行显示，该校正数据为被OSD显示数据覆盖后的当前校正数据。
