附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是现有的面板点灯机的结构示意图。
图2是本发明实施例一一种面板点灯机的结构示意图。
图3是本发明实施例中显示屏上的图像在检测面板上叠加显示的示意图。
图4是本发明实施例二一种面板点灯测试系统的架构示意图。
图5是本发明实施例中对检测面板不良位置拍照的示意图。
图6是本发明实施例中点灯测试界面示意图。
图7是本发明实施例三一种面板点灯测试方法的流程示意图。
具体实施方式
以下各实施例的说明是参考附图，用以示例本发明可以用以实施的特定实施例。
请参照图2所示，本发明实施例一提供一种面板点灯机，包括：
支撑体1；
设置在支撑体1上的工作台10，用于容纳并固定检测面板13；
设置在工作台10后方的显示屏12，用于在点灯测试时为检测面板13提供背光以及显示设定图像，所述设定图像被投射到检测面板13上叠加显示。
本实施例的面板点灯机在工作台后设置一显示屏，该显示屏可以显示任何图像，例如整个显示区域显示白色图像时就相当于检测面板的背光，还可以显示示圆圈、线条、方框等各种图像。具体如图3所示，如前所述，显示屏12可以显示任何图像，以显示整面白色画面加上其上具有一黑色圆圈A的图像为例，检测面板13在没有控制信号、没有背光的情况下显示为黑色，当接通背光、通过控制信号控制检测面板显示整面的诸如白、红、绿、蓝、黑和灰阶等画面，此时显示屏12显示的整面白色画面加上一黑色圆圈A的图像将被叠加在检测面板13上显示。因此通过在工作台10后设置一显示屏12，能够实时显示制程中检测到的检测面板的不良图像，以辅助检测人员判定不良成因。
进一步地，显示屏12的显示区域尺寸大于或等于检测面板13的显示区域尺寸，这样，不同尺寸的检测面板13在工作台10上更换时，显示屏12的显示区域可以进行相应的显示范围调节，达到工作台10上其它非检测面板区域不漏光的目的，同时也避免更换治具，减少时间精力消耗，提高点灯测试效率。
请再参照图4所示，本发明实施例二提供一种面板点灯测试系统，包括：
面板点灯机，所述面板点灯机进一步包括：支撑体1；设置在支撑体1上的工作台10，用于容纳并固定检测面板13；设置在工作台10后方的显示屏12，用于在点灯测试时为检测面板13提供背光以及显示设定图像，所述设定图像被投射到检测面板13上叠加显示；
点灯机控制装置2，与所述显示屏12电连接，用于控制所述显示屏12显示设定图像；
信号发生器3，分别与点灯机控制装置2和检测面板13电连接，用于产生点灯测试信号控制检测面板13显示相应画面。
本实施例的面板点灯测试系统开始点灯测试时，首先由点灯机控制装置2向显示屏12发送控制信号，使显示屏显示整面白色图像(相当于提供背光)。然后点灯机控制装置2向信号发生器3发送控制信号，使信号发生器3产生相应的点灯测试信号，控制检测面板13依次显示整面白色、红色、绿色、蓝色、灰阶、黑色画面。检测人员进行点灯现象观察，找出不良点，通过输入设备4点选，让点灯机控制装置2记录该不良位置的坐标信息。需要说明的是，点灯机控制装置2具有一与显示屏12同步显示的屏幕20，当检测人员发现检测面板13上的不良点后，则操作输入设备4在该屏幕20上标识该不良点位置。由于显示屏12上的图像(此时为整面白色画面)是叠加在检测面板13上显示，输入设备4在屏幕20上的指针同时也会出现在显示屏12上，因此，通过输入设备4标识出的检测面板13的不良点位置是显示在显示屏12(同步显示在点灯机控制装置2的屏幕20)上。
标识不良点时同时显示有其坐标信息，点灯机控制装置2将根据检测面板13的ID去查询工厂系统(FAB System)5中该检测面板13在制程中该坐标点位下的不良图片。请参照图5所示，例如在该检测面板13的制程中某一检测点，对其不良点B进行了光学拍照，带有不良点B的不良图片被存储到工厂系统5。前述点灯测试时检测人员发现检测面板13上具有一不良点，通过输入设备4标识其位置如图6右上角的虚线框，同时会显示该不良点坐标信息，点灯机控制装置2按照该坐标信息查询到检测面板在制程中被拍摄的、具有相同坐标不良点的图片，即图5所示的不良图片，将其提取出来显示到显示屏12上。由于检测面板在制程中被拍摄有许多张图片，但是这些图片不一定是检测人员在点灯测试时发现的不良位置所对应的那张图片，因此，通过前述方式可以将需要的图片找出来做储存，储存在点灯机控制装置2以及工厂系统5里。
该不良图片显示在显示屏12上，检测人员则可以依据该不良图片以及点灯测试经验，判断造成不良的真因，最后将该不良图片作为该不良点的解析图片保存在点灯机控制装置2上，并上传至工厂系统5。
由上可知，本发明实施例中，显示屏12显示的设定图像，除了用作背光的整面白色图像之外，还包括点灯机控制装置2获取的检测面板13在制 程中被拍摄的不良图片。
本实施例面板点灯测试系统还包括输入设备4，与点灯机控制装置2电连接，用于在点灯测试时对检测面板13的不良点位置进行标识。作为一个例子，输入设备4为鼠标。
进一步地，显示屏12的显示区域尺寸大于或等于检测面板13的显示区域尺寸，这样，不同尺寸的检测面板13在工作台10上更换时，点灯机控制装置2可以调节显示屏12的显示范围，达到工作台10上其它非检测面板区域不漏光的目的，同时也避免更换治具，减少时间精力消耗，提高点灯测试效率。
请再参照图7所示，相应于本发明实施例二，本发明实施例三提供一种面板点灯测试方法，包括：
点灯机控制装置向显示屏发送控制信号，使显示屏显示整面白色图像；
点灯机控制装置向信号发生器发送控制信号，使信号发生器产生点灯测试信号，控制检测面板显示相应画面；
发现检测面板上的不良点后，对所述不良点进行标识；
根据检测面板的ID及所述不良点的坐标信息，查询获得检测面板在制程中被拍摄的、具有相同坐标不良点的图片，并将所述图片显示在显示屏上。
本发明实施例可以适用于各种尺寸的面板点灯测试，并且除了简易式检测(Shorting bar)方式之外，还可进行全接触式检测(Full contact)。
通过上述说明可知，本发明实施例的有益效果在于：通过在面板点灯机的工作台之后增设可以显示任何图像的显示屏，不仅为检测面板提供背光，还能够实时显示制程中检测到的检测面板的不良图像，以辅助检测人员判定不良成因；通过输入设备对点灯测试中发现的不良点进行标识，可以查询获得检测面板在制程中被拍摄的、具有相同坐标不良点的图片，供检测人员判断；显示屏的显示范围可以根据不同检测面板的尺寸进行调节，达到工作台上其它非检测面板区域不漏光的目的，同时也避免更换治具，减少时间精力消耗，提高点灯测试效率。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的 范围。
