【具体实施方式】
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明所提供的一种封装材料的水汽透过率测试设备及方法做进一步详细描述
参阅图1，本发明一种封装材料的水汽透过率测试设备包括：测试腔体10、拍摄设备11、测试电路12及光源13。
其中，测试腔体10为一个恒温恒湿的环境，本实施方案以恒温恒湿箱为例。
测试腔体10内设置承载平板/架101，在本实例中，承载平板/架101为一块整体的平板/架。承载平板/架101上放置待测试物体102，测试电路12连接至承载平板/架101，用于电连接待测试物体102，其中待测试物体102为活泼金属，导电性良好并易于与水蒸气和氧气发生反应。
此外，承载平板/架101上设置有电极103，用于连接/接插待测试物体102，电极103有正负电极，分别设置在承载平板/架101两端，与待测试物体102两端连接/接插，电极103与测试电路12连接。此时，测试电路12、电极103和待测试物体102形成一个电流回路，当测试电路12通电时，电流从电极103和待测试物体102中通过，根据待测试物体102电流、电压和电阻中至少一个的变化值，测试待测试物体102的电学特性。
进一步地，拍摄设备11用于在测试电路12对待测试物体102进行电性测试的至少部分时间内，对待测试物体102进行光学测试。光源13发出的光线被拍摄设备11接收，形成光路，拍摄设备11和光源13分别置于待测试物体102两边，且光源13和拍摄设备11之间形成的光路通过待测试物体102。
其中，承载平板/架101上放置待测试物体102的区域透光，光源13发出的光线通过承载平板/架101的透光区域穿透待测试物体102，被拍摄设备11接收，拍摄设备11可获得包括但不限于待测试物体102的透过光强度及区域的信息，测试出待测试物体102的透光率、透光阴影、发光缺陷中至少一种的光学特性。
参阅图2，本发明封装材料的水汽透过率测试设备另一实施方式包括：
在图1所示技术方案的基础上，在承载平板/架201上安装一个密封罩24，把待测试物体202与空气隔开，其中密封罩24包括金属覆盖层241、盖板243及两者之间的密封胶242。金属覆盖层241设置于承载平板/架201上，数量为二，分别位于承载平板/架201两端并与待测试物体202两端的电极203连接，盖板243位于待测试物体202和拍摄设备21之间，盖住待测试物体202，两者之间涂满密封胶242，其中，金属覆盖层201为导电性良好的金属，密封胶242具有多孔性，盖板243透光性良好，本实施案例盖板243以玻璃盖板为例。
使用时，测试电路22通电，与金属覆盖层241、电极203和待测试物体202形成电流回路；打开光源23及拍摄设备21，光源23发出光线，经过承载平板/架201上的透光区域照射到待测试物体202。与此同时，恒温恒湿箱20里包含水蒸气和氧气的空气通过具有多孔性的密封胶242进入密封罩24内，与待测试物体202接触，并发生反应，随着时间的延续，待测试物体202逐渐变薄直至局部进而全部透光。在此过程中，待测试物体202的电流、电阻及电压发生变化，可以此测出待测试物体的电流、电阻及电压中至少一项电学特性；与此同时，随着待测试物体202的变薄并透光，光源23发出的光线可穿透待测试物体202，进而通过玻璃盖板243被上方的拍摄设备21接收，拍摄设备21可获得包括但不限于待测试物体202的透过光强度及区域的信息，以此测试待测试物体202的透光率、透光阴影、发光缺陷中至少一种的光学特性。
对于测试待测试物体202的发光缺陷等来说，光源23可以省略，拍摄设备21直接获取待测试物体202的发光情况。

本实施案例中待测试物体202为活性金属，在其他实施案例中，上述设备亦可将OLED样品作为待测试物体202，进行 OLED样品的在恒温恒湿环境下对水蒸气和氧气的耐久性测试，此时，OLED样品与电极203连接，测试电路22通电，OLED样品发光，发出的光线穿过玻璃盖板243被上方的拍摄设备21接收，恒温恒湿箱20内的水蒸气和氧气穿过密封胶242与OLED样品的金属电极发生反应或破坏有机层，随着时间的延续，OLED样品的发光区域逐渐失效，暗点区域数量变多、面积变大，上方的拍摄设备21记录变化的图像，以此测试出OLED样品对水蒸气和氧气的耐久性。
