下文的公开提供了许多不同的实施方式或例子用来实现本发明的不同结构。为了简化本发明的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本发明。此外，本发明可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本发明提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
请参阅图1，本发明实施方式的对位装置100用于对准显示面板200及压头300。显示面板200设置有对位标识202，压头300设置有与对位标识202对应的对准标识302。对位装置100包括反射组件10和图像获取装置30。其中，反射组件10用于反射对位标识202及对准标识302。图像获取装置30与对位标识202及对准标识302对应，图像获取装置30用于拍摄反射组件10反射的对位标识202和对准标识302以得到对位标识图像和对准标识图像。对位标识图像和对准标识图像用于辅助调整显示面板200和压头300处于对准状态。
本发明实施方式的对位装置100可以应用于本发明实施方式的测试设备1000，其中，测试设备1000用于测试显示面板200。也即是说，本发明实施方式的测试设备1000包括本发明实施方式的对位装置100。此外，测试设备1000还包括压头300。压头300用于压接显示面板200以为显示面板200提供输入信号。
本发明实施方式的对位装置100和测试设备1000通过反射组件10反射对位标识202和对准标识302以便图像获取装置30能够拍摄到对位标识图像和对准标识图像，并根据对位标识图像和对准标识图像调整显示面板200与压头300之间的相对位置，从而可以精确地对准显示面板200和压头300，便于压头300与显示面板200之间的精准压接。
在某些实施方式中，图像获取装置30可以是摄像头或者携带有摄像头的电子装置等。图像获取装置30应具有自动对焦功能以便拍摄到清晰的对位标识图像和对准标识图像。
请再参阅图1，在某些实施方式中，对位装置100还包括处理器50。处理器50用于根 据对位标识图像和对准标识图像获取对位标识202和对准标识302的位置差异信息以调整显示面板200和压头300处于对准状态。处理器50获取到对位标识图像和对准标识图像后，识别对位标识图像中的对位标识202所在像素位置，并识别对准标识图像中的对准标识302所在像素位置。如此，处理器50即可根据对位标识202所在像素位置与对准标识302所在像素位置之间的位置差异确定实际场景中显示面板200的对位标识202与压头300的对准标识302之间的位置差异信息。
请参阅图2，在某些实施方式中，对位装置100还包括显示屏60。显示屏60用于显示对位标识图像和对准标识图像。具体地，显示屏60可重叠地将对位标识图像和对准标识图像进行显示。若显示屏60中显示的对位标识图像中的对位标识202和对准标识图像中的对准标识302的位置不重合，则用户可根据显示屏60上显示的对位标识202和对准标识302之间的相对位置差异调整显示面板200与压头300之间的相对位置，直至显示屏60上显示的对位标识202和对准标识302重合。其中，显示屏60可通过有线方式与图像获取装置30连接，以获取图像获取装置30拍摄的对位标识图像和对准标识图像。此外，显示屏60还可通过无线方式与图像获取装置30连接，例如，WiFi通信方式、蓝牙通信方式等，以从图像获取装置30获取对位标识图像和对准标识图像。
在某些实施方式中，反射组件10包括直角棱镜。具体地，请再参阅图1，直角棱镜的直角朝显示面板200所在方向放置。直角棱镜中夹角呈90°的两个镜面中会显示对位标识202或对准标识302，放置在直角棱镜两边的图像获取装置30拍摄成像镜面上的对位标识202或对准标识302以得到对位标识图像或对准标识图像。
请参阅图4，在某些实施方式中，反射组件10包括两个夹角呈90°放置的反射镜12。其中，两个反射镜12围成的直角朝显示面板200所在方向放置。两个反射镜12上会显示对位标识202或对准标识302，放置在反射组件10两边的图像获取装置30拍摄成像镜面上的对位标识202或对准标识302以得到对位标识图像或对准标识图像。
请参阅图3，在某些实施方式中，对位装置100还包括反射组件支撑件20。反射组件支撑件20的高度可调节。对位装置100还包括图像获取装置支撑件40。图像获取装置支撑件40的高度可调节。
可以理解，当显示面板200的规格较小时，此时可能对应的对位标识202也较小，相应地，与显示面板200规格相对应的压头300上的对准标识302也较小。根据平面镜成像的特点，物体离镜面的距离越远，物体在镜面上成的像越小。因此，可以通过调节反射组件支撑件20以增加反射组件10的高度，从而使反射组件10更加靠近对位标识202和对准标识302。如此，对位标识202和对准标识302在反射组件10上的成像较大。对应地，调节图像获取装置支撑件40以增加图像获取装置30的高度，使得图像获取装置30尽量对准 对位标识202和对准标识302在镜面上的成像位置。如此，图像获取装置30可以拍摄到清晰且形状较大的对位标识202和对准标识302，方便后续的位置差异信息的计算和显示面板200或压头300的位置的调节。
在某些实施方式中，对位标识202和对准标识302均可为文字、图案等。例如，对位标识202和对准标识302可以是“T”型、“十”字型、圆符号“⊙”等。其中，对位标识202应与对准标识302一致。如此，才能实现显示面板200与压头300的精确对准。
在某些实施方式中，图像获取装置30的数量可以为一个。此时对位标识202的数量为一个，对准标识302的数量为一个，且对位标识202包括至少一根线条，对准标识302包括至少一根线条。
请一并参阅图1和图4，可以理解，要确保显示面板200和压头300精确对准，则需要确保对位标识202和对准标识302在图1所示的x轴方向上的位置和y轴方向上的位置均对准。因此，当图像获取装置30数量为一个时，对位标识202至少包括一根线条，对准标识302包括至少一根线条，当对位标识202的线条和对准标识302的线条完全重合时则表明显示面板200和压头300已处于对准状态。
具体地，图像获取装置30拍摄到对位标识图像和对准标识图像后，处理器50可识别出对位标识图像中对位标识202所在的多个像素的坐标，并识别出对准标识图像中对准标识302所在的多个像素的坐标。随后，处理器50再根据对位标识202对应的像素坐标和对准标识302对应的像素坐标计算出位置差异信息。
请一并参阅图1和图5，在某些实施方式中，图像获取装置30的数量为一个，对位标识202的数量为至少两个，对准标识302的数量为至少两个。
具体地，当图像获取装置30的数量为一个时，多个的对位标识202应处于反射组件10中同一镜面所对应照射到的显示面板200的位置处，且多个对准标识302也应处于反射组件10中同一镜面所对应照射到的显示面板200的位置处，则当两个对位标识202分别与对应的对准标识302重合时，显示面板200和压头300即处于对准状态。
请一并参阅图1和图6，在某些实施方式中，图像获取装置30的数量为至少两个，对位标识202的数量为至少两个，且对准标识302的数量为至少两个。此时，多个对位标识202可均匀或非均匀地分布在显示面板200上，同样地，对准标识302可相应地均匀或非均匀地分布在压头300上。当多个对位标识202分别与对应的对准标识302重合时，显示面板200和压头300即处于对准状态。
在本发明的具体实施例中，图像获取装置30的数量为两个，对位标识202的数量为两个，分别分布在显示面板200的两端。对准标识302的数量的为两个，分别分布在压头300与显示面板200压接的底面的两端。反射组件10放置在两个图像获取装置30之间(如图 6所示，位于反射组件10左侧的图像获取装置30为左图像获取装置，位于反射组件10右侧的图像获取装置30为右图像获取装置)。两个对位标识202中的一个成像在反射组件10的一个镜面上，另一个对位标识202成像在反射组件10的另一个镜面上。两个对准标识302中的一个成像在反射组件10的一个镜面上，另一个对准标识302成像在反射组件10的另一个镜面上。成像在反射组件10左侧的对准标识302和对位标识202由左图像获取装置拍摄以分别得到左侧的对准标识图像和对位标识图像；成像在反射组件10右侧的对准标识302和对位标识202由右图像获取装置拍摄以分别得到右侧的对准标识图像和对位标识图像。处理器50计算左侧的对准标识图像和对位标识图像之间的位置差异以得到左侧的位置差异信息，并计算右侧的对准标识图像和对位标识图像的位置差异以得到右侧的位置差异信息，并根据左侧的位置差异信息和右侧的位置差异信息调整显示面板200和压头300处于对准状态，此时左侧的对位标识202和对准标识302完全重合，右侧的对位标识202和对准标识302也完全重合，显示面板200和压头300可精准压接。
请再参阅图1，在某些实施方式中，测试设备1000还包括载台500。载台500用于放置显示面板200。
在某些实施方式中，图像获取装置30的光轴平行于载台500(如图1所示)。如此，图像获取装置30才可拍摄到反射组件10反射的对位标识202和对准标识302。
请再参阅图1，在某些实施方式中，测试设备1000还包括透明板600。透明板600沿载台500延伸。透明板600用于承载显示面板200。对位标识202和对准标识302均与透明板600对应。
具体地，显示面板200放置在载台500上时，显示面板200的一部分不能被载台500的承载面遮挡。如此，图像获取装置30才可拍摄到显示面板200上的对位标识202。然而，由于压头300压接显示面板200时会对显示面板200施加一定压力，为防止显示面板200受力损坏，因此，需要设置一块沿载台500延伸的透明板600以用于支撑显示面板200。如此，一方面对位标识202通过透明板600后仍可在反射组件10的某一镜面上成像从而反射到图像获取装置30上以供图像获取装置30拍摄，另一方面由于透明板600的支撑作用又可避免显示面板200在压接时因缺乏支撑力而损坏的问题。
在某些实施方式中，透明板600的材料可以是石英、树脂、二氧化硅中的任意一种。也即是说，透明板600由石英制成，也可以由树脂制成，还可由二氧化硅制成。
请再参阅图1，在某些实施方式中，测试设备1000还包括驱动件400。驱动件400用于根据位置差异信息驱动显示面板200和/或压头300移动以使显示面板200和压头300对准。
具体地，图像获取装置30首先拍摄对准标识图像。随后，由测试人员将显示面板200 放置在载台500上，或者由测试设备1000自动进片将显示面板200放置在载台500上。此时，图像获取装置30拍摄对位标识图像。随后，处理器50识别对位标识图像中的对位标识202所在的像素的坐标，并识别对准标识图像中对准标识302所在的像素的坐标，再根据对位标识202所在像素的坐标和对准标识302所在像素的坐标计算出位置差异信息。驱动件400则根据位置差异信息调整显示面板200和压头300的相对位置以使得对位标识202和对准标识302完全重合，此时显示面板200和压头300即可实现精准压接。其中，驱动件400可通过调节显示面板200的位置以对准显示面板200和压头300；或者，驱动件400可通过调节压头300的位置以对准显示面板200和压头300；或者，驱动件400可同时调节显示面板200和压头300的位置以对准显示面板200和压头300。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
