OLED显示器热带雨林环境适应性研究

为开展OLED显示器在热带雨林气候条件下的环境适应性研究,将OLED显示器置于西双版纳试验站进行库内自然暴露试验,并定期对样品进行观察和检测。经过一年的暴露试验,OLED显示器表面出现针孔、黑点和膜层脱落等现象,以及发光面积减小和亮度降低等性能衰减变化。研究发现,OLED显示器在热带雨林环境中长期受温度、湿度等环境因素的交变应力作用,其密封性遭到破坏,外界氧气、水汽等进入显示器内部,最终导致OLED显示器失效。因此,要想进一步提高OLED显示器在热带雨林环境中的使用寿命,关键在于改善OLED显示器的密封性。

Dissecting the Adaptability of OLED Displays in Tropical Rainforest

To study the environmental adaptability of OLED displays in tropical rainforest,OLED displays are placed into the storeroom of experimental station in Xishuangbanna,and they are observed and tested regularly.After one-year-exposure,the surface of OLED displays appears pinhole,black point,and obscission.In addition,the area of luminescence and brightness were reduced.Investigation revealed:the sealing of OLED displays is destroyed in tropical rainforest,subjected to the long term alternating stress caused by temperature and humidity,thus led to the failure of OLED with oxygen and moisture in the interior of displays.Therefore,an improved sealing is the key to the service life of OLED displays in tropical rainforest.
