OLED is watched with interest as the next generation flat-panel display. However, the organic luminescence layer and the cathode are extremely weak to moisture. OLED is deteriorated as generating a dark spot -- Black Spot Defect -- by the infiltrated moisture.

Dynic Corporation proposes "HIGH FUNCTION MOISTURE GETTER SHEET -- DESICCANT" to make OLED to be long life

Moisture absorption mechanism
CaO Type : CaO + H2O →　Ca(OH)2
SrO Type : SrO + H2O →　Sr(OH)2

• Does not release moisture to the degree of 400°C
• Moisture absorption speed is very fast.
• Easy to handle because sheet type.
