具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请的技术方案，并不用于限定本申请。
为了更好的理解本申请的技术方案，下面将结合说明书附图以及具体的实施方式进行详细的说明。
本申请实施例的主要解决方案是：获取LED显示屏的像素点数值；通过所述像素点数值确定表征LED显示屏不同点亮状态的像素密度蒙版集合；基于所述像素密度蒙版集合中的各个像素密度蒙版对待显示图案进行扫描，得到目标显示图案；通过所述目标显示图案控制所述LED显示屏进行渐变显示。
在本实施例中，为便于表述，以下以识别LED显示屏显示控制设备为执行主体进行阐述。
由于现有技术中单色LED显示屏仅仅具有点亮和熄灭两种状态，无法根据用户需求灵活对显示屏显示界面进行调整，若需要对显示屏进行渐变显示，则需要通过多色LED显示屏进行显示，但多色显示屏的成本较高，仅使用单色LED显示屏无法灵活根据用户需求进行显示调整。
本申请提供一种解决方案，使单色LED显示屏可在显示的基础上加入渐隐渐显的效果，降低显示的成本同时提升用户使用体验。
从上述实施例可知，本申请由于先获取LED显示屏的像素点数值；通过所述像素点数值确定表征LED显示屏不同点亮状态的像素密度蒙版集合；基于所述像素密度蒙版集合中的各个像素密度蒙版对待显示图案进行扫描，得到目标显示图案；通过所述目标显示图案控制所述LED显示屏进行渐变显示， 克服了单色LED显示屏显示单一、显示不够灵活的技术问题，从而达到了在显示的基础上加入渐隐渐显的效果，既降低了成本，又提高LED显示屏的显示效果，提升了用户体验。
需要说明的是，本实施例的执行主体可以是一种具有数据处理、网络通信以及程序运行功能的计算服务设备，例如平板电脑、个人电脑、手机等，或者是一种能够实现上述功能的电子设备、LED显示屏显示控制设备等。以下以LED显示屏显示控制设备为例，对本实施例及下述各实施例进行说明。
基于此，本申请实施例提供了一种LED显示屏显示控制方法，参照图1，图1为本申请LED显示屏显示控制方法第一实施例的流程示意图。
本实施例中，所述LED显示屏显示控制方法包括步骤S10～S40：
步骤S10：获取LED显示屏的像素点数值。
需要说明的是，LED显示屏为单色LED显示屏，例如固定式单色LED显示屏，用于显示静态或滚动的文本信息、图形或简单的动画；柔性单色LED显示屏等。
单色LED显示屏的像素点数值可为单色LED显示屏上各像素点的数值，通过构建显示数组可记录像素点数值，熄灭数值定义为0，点亮数值定义为1，可先通过对单色LED显示屏中的像素点进行划分，并获取划分后的像素点的像素点数值。
另外地，需要说明的是，为了实现渐隐渐显的效果，可将LED显示屏中的像素点进行重新划分。
在一种可行的实施方式中，步骤S10可以包括步骤A11～A14：
步骤A11，获取LED显示屏的原始像素点；
需要说明的是，原始像素点为单色LED显示屏上未进行划分的像素点。
如图2所示，图2为单色LED显示屏显示示意图，单色LED显示屏由多个像素点构成，即原始像素点，每个像素点仅仅具有点亮和熄灭的功能。
为了实现渐隐渐显的显示效果，本实施例将原始像素点进行重新划分。
步骤A12，对所述原始像素点进行划分，得到多组划分像素点；
需要说明的是，对原始像素点进行划分时，可先设置划分规则，例如每组新像素点的数量，例如设置每组新像素点的数量为4个、6个、8个等，可根据具体需求进行设置，每组新像素点的数量越多，构成的像素密度蒙版越细致。
例如划分规则为每组新像素点的数量为4个，则通过对原始像素点进行划分，每4个划分为一组，每一组为划分像素点，从而得到多组划分像素点。如图3所示，图3为对原始像素点进行划分得到多组划分像素点的示意图，将相邻每四个像素点(田字格)构成一组像素点，从而得到多组划分像素点。
步骤A13，基于预设画点函数对所述多组划分像素点进行定位，得到划分像素点位置；
可以理解的是，预设画点函数可通过C语言构建得到，预设画点函数Point(x,y)的作用是定位划分像素点中的每个像素点，可分别对每组划分像素点进行定位，从而快速确定划分像素点的位置。
进一步地，基于预设画点函数对所述多组划分像素点进行定位，得到划分像素点位置的步骤包括：基于预设画点函数对所述多组划分像素点中的每组划分像素点进行定位，得到划分像素点坐标；通过所述划分像素点坐标得到划分像素点位置。
需要说明的是，可将每组划分像素点进行坐标划分，从而得到组内各个划分像素点坐标，可通过划分像素点坐标快速得到划分像素点位置。如图4所示，图4为对划分像素点进行定位，得到划分像素点坐标的过程示意图，例如划分像素点中包括有四个像素点，通过对每个像素点进行坐标划分，分为左上角(0,0)，右上角(1,0)，左下角(0,1)和右下角(1,1)，以此类推，可得到单色显示屏中所有划分像素点的位置。
步骤A14，通过所述划分像素点位置确定LED显示屏的像素点数值。
需要说明的是，可通过划分像素点位置确定LED显示屏中各个划分像素点的像素点数值。
具体地，可提前设置记录像素点数值的规则，从而快速确定各个划分像素点数值，则通过所述划分像素点位置确定LED显示屏的像素点数值的步骤包括：
获取预设数值记录规则；遍历所述划分像素点位置，得到每组划分像素点中不同像素点点亮数量；通过所述预设数值记录规则对所述像素点点亮数量进行像素点数值记录，得到LED显示屏的像素点数值。
需要说明的是，预设数值记录规则为定义像素点数值的记录规则，可构建显示数组Show[n]，通过显示数组记录当前像素点的数值，熄灭数值定义为0，点亮数值定义为1，通过对划分像素点位置遍历，可得到每组划分像素点中不同像素点点亮数量，例如划分像素点中像素点数量为4个，则点亮数量可包括5种：全部熄灭，即点亮数量为0；只点亮一个点，点亮数量为1；点亮2个点，点亮数量为2；点亮三个点，点亮数量为3；全部点亮，点亮数量为4。通过不同像素点点亮数量得到各个划分像素点的像素点数值，从而得到LED显示屏中所有像素点的像素点数值。
步骤S20：通过所述像素点数值确定表征LED显示屏不同点亮状态的像素密度蒙版集合。
需要说明的是，可通过像素点数值确定像素点点亮数量，根据像素点点亮数量的不同，可得到表征LED显示屏不同点亮状态的像素密度蒙版集合。
像素密度蒙版集合中包括了不同像素点密度蒙版，像素密度蒙版即为灰度蒙版，例如像素密度蒙版集合中包括有像素密度为0％的蒙版，即显示屏上所有像素点全部熄灭，像素点数值均为0，还可包括像素密度为50％的蒙版，像素密度为100％的蒙版等，可根据像素点划分规则确定划分像素点数量得到回复蒙版数量，例如划分像素点数量为n，则有n-1种灰度蒙版。
步骤S30：基于所述像素密度蒙版集合中的各个像素密度蒙版对待显示图案进行扫描，得到目标显示图案。
在具体实施中，像素密度蒙版集合中有不同像素密度的蒙版，可通过不同的像素密度蒙版对待显示图案进行扫描，从而得到新的扫描图案。
待显示图案即为用户需要在单色LED显示屏上显示的图案，通过将待显示图案与对应像素密度蒙版进行叠加，从而可得到对应的显示图案，如图5所示，图5为单色LED显示屏待显示图案和50％灰度蒙版叠加示意图，例如当前单色LED显示屏的待显示图案为显示一个大写字母E，将其与像素密度为50％的灰度蒙版相互重叠，可以发现，显示屏图案和灰度蒙版有一部分像素点是重合的，可通过对不同像素密度的灰度蒙版与待显示图案进行叠加和扫描处理，从而可得到多个目标显示图案。
步骤S40：通过所述目标显示图案控制所述LED显示屏进行渐变显示。
在具体实施中，可通过目标显示图案控制LED显示屏进行渐变显示。渐变显示即为控制单色LED显示屏进行渐隐渐显的显示。
进一步地，可根据不同用户显示需求进行不同的显示，则步骤S40包括：
获取显示指令；根据所述显示指令确定密度显示时序；通过所述密度显示时序控制所述目标显示图案中不同显示密度的显示图案依次在所述LED显示屏上进行渐变显示。
可以理解的是，显示指令可包括目标显示图案的显示密度从高到低或目标显示图案的显示密度从低到高，可根据具体需求进行选择。
在具体实施中，可通过对显示指令进行分析，从而确定密度显示时序，例如密度显示时序为从低到高进行显示，则可通过密度显示时序控制目标显示图案中低显示密度的显示图案先在LED显示屏上显示，再控制目标显示图案中高显示密度的显示图案后在LED显示屏上显示。
为了实现渐隐渐显的效果，可建立灰度函数Gray(x)，通过灰度函数Gray(x)依次调用不同灰度蒙版中显存数组Show[n]中的数值，即调用不同像素点密度的目标显示图案，例如实现从无到有的效果，可按照如下像素密度蒙版从0％→25％→50％→75％→100％依次显示目标显示图案，实现从有到无的效果，可按照如下像素密度蒙版从100％→75％→50％→25％→0％依次显示目标显示图案。
本实施例通过获取LED显示屏的像素点数值；通过所述像素点数值确定表征LED显示屏不同点亮状态的像素密度蒙版集合；基于所述像素密度蒙版集合中的各个像素密度蒙版对待显示图案进行扫描，得到目标显示图案；通过所述目标显示图案控制所述LED显示屏进行渐变显示，可通过像素密度蒙版集合对待显示图案进行扫描，在显示的基础上加入渐隐渐显的效果，既降低了成本，又提高LED显示屏的显示效果，提升了用户体验。
基于本申请第一实施例，在本申请第二种实施例中，与上述实施例一相同或相似的内容，可以参考上文介绍，后续不再赘述。在此基础上，请参照图6，步骤S20，具体包括：
步骤S201：通过所述像素点数值确定像素点点亮数量。
需要说明的是，可通过像素点数值确定像素点点亮数量，例如像素点数值为0，则像素点点亮数量为0，若在每组划分像素点内，像素点数值分别为1,0,0,0，则像素点点亮数量为1。
以此类推，可根据每组划分像素点内的像素点数值确定像素点点亮数量。
步骤S202：根据所述像素点点亮数量对显示屏点亮状态进行划分，得到显示屏多种点亮状态。
在具体实施中，可通过像素点点亮数量对显示屏点亮状态进行划分，从而得到显示屏多种点亮状态，如图7所示，图7为划分像素点不同点亮状态示意图，通过划分像素点中四个像素点的点亮数量不同，可分为五种状态，包括全部熄灭、只点亮一个点(0,0)、点亮两个点(0,0)和(1,1)、点亮三个点(0,0)，(1,0)和(1,1)、全部点亮(0,0)，(1,0)，(1,1)和(0,1)。
步骤S203：通过所述显示屏多种点亮状态构建像素密度蒙版集合。
在具体实施中，如果用上述多种点亮状态填满整个显示屏的屏幕，即可得到不同像素点密度的视觉效果，即灰度蒙版，通过将不同像素点密度的灰度蒙版进行汇总，可得到像素密度蒙版集合。
作为一种示例，若每组划分像素点点亮状态包括全部熄灭、只点亮一个点、点亮两个点、点亮三个点、以及全部点亮五种状态，则得到的像素点密度为0％，25％，50％，75％和100％，如图8所示，图8为不同像素密度的显示效果示意图，从左到右依次为全部熄灭对应的像素点密度0％、只点亮一个点对应的像素点密度25％、点亮两个点对应的像素点密度50％、点亮三个点对应的像素点密度75％以及全部点亮对应的像素点密度100％。
本实施例通过所述像素点数值确定像素点点亮数量；根据所述像素点点亮数量对显示屏点亮状态进行划分，得到显示屏多种点亮状态；通过所述显示屏多种点亮状态构建像素密度蒙版集合，可快速根据像素点数值构建不同像素点密度的灰度蒙版，从而可通过灰度蒙版实现显示屏不同的显示效果，无需改变显示屏的硬件结构，降低成本。
基于本申请第一实施例，在本申请第二种实施例中，与上述实施例一相同或相似的内容，可以参考上文介绍，后续不再赘述。在此基础上，请参照图9，步骤S30，具体包括：
步骤S301：基于所述像素密度蒙版集合中的各个像素密度蒙版得到汇总像素点坐标。
需要说明的是，可根据像素密度蒙版集合得到不同像素密度蒙版，并将每个像素密度蒙版进行统计，得到每个像素密度蒙版中各个像素点坐标，将所有像素点坐标汇总，得到汇总像素点坐标。
步骤S302：通过所述像素密度蒙版对待显示图案中各个点进行扫描，将所述待显示图案中与所述汇总像素点坐标中相同位置的像素点进行比较。
在具体实施中，通过不同的像素密度蒙版分别对待显示图案中各个点进行扫描，将待显示图案上与汇总像素点坐标中相同位置的像素点进行比较。
例如以50％灰度蒙版上的像素点坐标为对象逐一扫描，与待显示图案上相同位置的像素点进行比较。
步骤S303：在所述待显示图案上对应的像素点的像素点数值为第一数值时，将所述像素点作为显示像素点，所述第一数值表示像素点显示为第一状态。
在比较过程中，如果待显示图案上对应的像素点的像素点数值为第一数值，则可将像素点作为显示像素点，第一数值即为1，对应的像素点状态应为点亮状态，显示像素点即为在后续进行显示时，像素点作为显示图案中的点亮点。
在具体实施中，第一数值表示像素点显示为第一状态，第一状态即为点亮状态。
步骤S304：在所述待显示图案上对应的像素点的像素点数值为第二数值时，跳过扫描所述像素点，直至扫描完成，得到显示像素点集合，所述第二数值表示为像素点显示为第二状态，所述第一状态和所述第二状态不同。
在比较时，若待显示图案上对应的像素点的像素点数值为第二数值，则跳过扫描此像素点，第二数字即为0，对应的像素点状态应为熄灭状态，第二状态即为熄灭状态。
通过将待显示图案上与像素密度蒙版各个像素点进行比较，从而扫描所有像素点，将像素点进行筛选，得到显示像素点集合。
步骤S305：通过所述显示像素点集合得到目标显示图案。
在具体实施中，可通过显示像素点集合构建一个新的显示图案，即目标显示图案。
通过不同像素点密度的灰度蒙版与待显示图案的叠加，从而可构建不同像素点密度的显示图案，最终得到多种像素点密度的目标显示图案。
例如将50％灰度蒙版上的像素点坐标为对象逐一扫描与待显示图案“E”进行比较，如果显示图案上对应的像素点的值是0(熄灭状态)，则跳过这个点继续扫描；如果对应的像素点的值是1(点亮状态)，那么就将此点作为显示像素点，还可通过显存数组Show[n]中用画点函数Point(x,y)在相同坐标位置画一个点，当显示屏上的待显示图案对应的所有点都全部扫描完之后，灰度蒙版和待显示图案上所有的有交集的像素点坐标就都以数值1的形式保存在显存数组Show[n]中。从而，就得到了一个像素点密度为50％的目标显示图案。同理，用另外不同像素点密度的灰度蒙版进行叠加扫描，就又可以得到另外三种像素点密度为25％，75％和100％的图案，如图10所示，图10为叠加不同像素密度灰度蒙版得到的目标显示图案效果示意图，从左到右依次为像素点密度为25％的目标显示图案、像素点密度为50％的目标显示图案、像素点密度为75％的目标显示图案以及像素点密度为100％的目标显示图案。
本实施例基于所述像素密度蒙版集合中的各个像素密度蒙版得到汇总像素点坐标；通过所述像素密度蒙版对待显示图案中各个点进行扫描，将所述待显示图案中与所述汇总像素点坐标中相同位置的像素点进行比较；在所述待显示图案上对应的像素点的像素点数值为第一数值时，将所述像素点作为显示像素点，所述第一数值表示像素点显示为第一状态；在所述待显示图案上对应的像素点的像素点数值为第二数值时，跳过扫描所述像素点，直至扫描完成，得到显示像素点集合，所述第二数值表示为像素点显示为第二状态，所述第一状态和所述第二状态不同；通过所述显示像素点集合得到目标显示图案，可快速将不同像素点密度的灰度蒙版与待显示图案进行扫描，从而得到多种不同显示密度的目标显示图案，提高图案的显示效果。
示例性地，为了助于理解本实施例结合上述实施例一后所得到的LED显示屏显示控制方法的实现流程，请参照图11，图11提供了一种LED显示屏显示控制方法的简要流程示意图，具体地：先构建预设画点函数Point(x,y)，通过预设画点函数定位LED显示屏中的图案像素点，并构建显存数组Show[n]，记录像素点数值，点亮状态记为1，熄灭状态记为0，通过像素点点亮数量不同，将显示屏划分为五种不同点亮状态，得到五种像素密度蒙版，并通过密度蒙版依次扫描显示图案，从而得到五种像素密度的新图案，并确定用户的指令是点亮还是熄灭，若是点亮，则按照像素密度蒙版从0％→25％→50％→75％→100％依次显示目标显示图案，若是熄灭，则按照像素密度蒙版从100％→75％→50％→25％→0％依次显示目标显示图案。
需要说明的是，上述示例仅用于理解本申请，并不构成对本申请LED显示屏显示控制方法的限定，基于此技术构思进行更多形式的简单变换，均在本申请的保护范围内。
