请参阅图1，图 1是本申请实施例提供的一种显示面板检测系统的示意性框图。该显示面板检测系统10包括：点灯设备11、控制设备12和摄像设备13，其中点灯设备11和摄像设备13均与主控设备12连接，主控设备12用于控制点灯设备11完成对显示面板的画面检测，摄像设备13用于拍摄处于画面检测中显示面板的图像。
需要说明的是，完成对显示面板的画面检测，该画面检测具体为对显示面板的点灯测试，用于检测该该显示面板是否有缺陷。
其中，控制设备12包括：存储器121和处理器122，存储器121和处理器122耦合连接。该存储器121存储有可执行程序代码；处理器122调用存储器121中存储的所述可执行程序代码，执行：

根据预设缺陷检测规则检测所述画面图像，以完成对所述母基板中的多个显示面板的画面检测。
具体地，如图2所示，点灯设备11用于同时对母基板20中的多个显示面板201进行画面检测，通过设置在点灯设备11上的摄像设备13获取处于画面检测中的大张母基板的图像，通过该图像判断各个显示面板的显示质量，检测出有缺陷的显示面板。
摄像设备13包括多个摄像头，多个摄像头位于点灯设备11上的母基板20的上方。摄像头例如为CCD（Charge Coupled Device，电荷耦合元件）摄像头，然不限于此，亦可为其他摄像头。
该显示面板检测系统是对大张的母基板进行画面检测，不同于现有画面检测系统，将母基板裂片后对单个显示面板进行画面检测。该显示面板检测系统可以快速批量地完成对显示面板的画面检测，同时还可避免产线的显示面板出现批量性异常。
请参阅图3，图3是本申请实施例提供的一种显示面板检测方法的示意流程图。该显示面板检测方法运行于上述显示面板检测系统中的控制设备中，该控制设备通过该显示面板检测方法控制点灯设备和摄像设备，以同时完成对母基板中的多个显示面板的画面检测，该画面测试可例如为显示面板的点灯测试。如图3所示，该显示面板检测方法，包括步骤S101~S104。
S101、输入电源电压到母基板中的多个显示面板；
在本申请的实施例中，具体地，通过点灯设备输入电源电压到母基板中的多个显示面板，其中所述点灯设备用于对所述母基板中的多个显示面板同时进行画面检测。
具体地，所述点灯设备用于安装大张母基板，以对所述母基板中的多个显示面板同时进行画面检测。该母基板包括多个显示面板，将该母基板裂片后进行相关制程处理，可以制作出多个显示面板成品。该显示面板包括但不限于液晶显示面板。
具体地，通过点灯设备开启母基板中的多个显示面板，点灯设备上设有多个测试顶针。当大张母基板安装在点灯设备上时，该测试顶针与显示面板上的测试接触点连接。点灯设备通过该测试顶针给所述显示面板提供驱动电压，以开启所述显示面板，即输入电源电压到母基板中的多个显示面板。
S102、向多个所述显示面板传输预设驱动信号以驱动所述显示面板显示预设测试画面。
在本申请的实施例中，所述预设驱动信号为驱动所述显示面板显示预设测试画面的信号。比如，驱动所述显示面板显示亮画面的信号。
其中，该预设测试画面包括但不限于：预设亮画面、预设暗画面、预设红画面、预设蓝画面和预设绿画面。不同的预设测试画面用于检测不同类型的缺陷。
具体地，向多个所述显示面板传输预设驱动信号以驱动所述显示面板显示预设测试画面为：所述控制设备控制该点灯设备向所述母基板中的多个所述显示面板传输预设驱动信号以驱动所述显示面板显示预设测试画面。
S103、采集所述显示面板显示所述预设测试画面时的画面图像。
在本申请的实施例中，所述控制设备控制所述摄像设备拍摄母基板中的多个所述显示面板显示所述预设测试画面时的画面图像，并将所述画面图像传送给控制设备的处理器进行相关处理分析。
具体地，采集所述显示面板显示所述预设测试画面时的画面图像，包括：通过设置所述点灯设备上方的多个摄像头从多个角度采集所述显示面板显示所述预设测试画面时的多个画面图像。多角度可以确保能够全面检测出显示面板的缺陷。
S104、根据预设缺陷检测规则检测所述画面图像，以完成对所述母基板中的多个显示面板的画面检测。
在本申请的实施例中，所述预设缺陷检测规则包括：点缺陷检测规则、线缺陷检测规则和斑点缺陷（Mura缺陷）检测规则。点缺陷检测规则为检测显示面板中的存在点缺陷的规则方法，能检测出显示面板中点缺陷。线缺陷检测规则和斑点缺陷检测规则亦类似，用于检测显示面板中线缺陷和斑点缺陷（Mura缺陷）。
对于通过设置所述点灯设备上方的多个摄像头从多个角度采集所述显示面板显示所述预设测试画面时的多个画面图像，则根据预设缺陷检测规则检测所述多个画面图像，以完成对所述母基板中的多个显示面板的画面检测。
上述本申请的实施例通过点灯设备开启母基板中的多个显示面板，其中所述点灯设备用于对所述母基板中的多个显示面板同时进行画面检测；向多个所述显示面板传输预设驱动信号以驱动所述显示面板显示预设测试画面；采集所述显示面板显示所述预设测试画面时的画面图像；根据预设缺陷检测规则检测所述画面图像，以完成对所述母基板中的多个显示面板的画面检测。该显示面板的检测方法可以同时完成多个显示面板的画面检测，提高了显示面板的画面检测效率。
此外，相对于现有的将母基板裂片成单个显示面板后在进行画面检测，由于画面检测是显示面板制程中的比较靠后的制程，单板画面检测不能及时发现显示面板制程中的批量异常。而该显示面板检测方法，可以实时在线检测，因此可以有效避免显示面板制程中的批量异常现象。
请参阅图4，图4是本申请实施例提供的一种显示面板检测方法的另一示意流程图。该显示面板检测方法运行于上述显示面板检测系统中的控制设备中，该控制设备通过该显示面板检测方法控制点灯设备和摄像设备，以同时完成对母基板中的多个显示面板的画面检测。如图4所示，该显示面板检测方法，包括步骤S201~S207。

其中，该位置信息是指子画面图像在所述画面图像中具体位置，比如母基板包括33排列方式的显示面板，可以从母基板的左下角建立坐标系。最简单的该位置信息为母基板的显示面板的标号，比如，显示面板201或显示面板205等，该位置信息用于提示用户具体在母基板中哪个显示面板出现了缺陷问题。
此外，若所述画面图像有子画面图像存在画面缺陷，在获取子画面图像在所述画面图像的位置信息的同时，还可以获取子画面图像的画面缺陷类型，其中所述画面缺陷类型包括点缺陷、线缺陷或斑点缺陷。
S206、根据所述位置信息标记出存在画面缺陷的所述子画面图像对应的显示面板并生成异常标记号。
在本申请的实施例中，该位置信息可以是显示面板在母基板中的标号，因此可以利用该标号标记出存在画面缺陷的子画面图像对应的显示面板，并生成异常标号。比如，子画面图像405存在点缺陷异常，则获取子画面图像405对应的显示面板205，将标号205生成异常标号。
