Moisture Getter for OLED

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 -- DESSICANT" to make OLED to be long life

Features:

  • The moisture getter sheet absorb and fix a small amount of moisture, and does not discharge again.

  • Because sticker is given to the one side of sheet, the installing on the sealing cap is easy. Moreover, it is convenient and does not take up space in equipment to supply with reel.

  • Cutting and the processing such as as piercing can be installed in the moisture getter sheet easily and compactly because of a thin, flexible sheet. An internal absorption material never drops out by moisture absorption

  • The moisture getter sheet does not use poisonous materials. This sheet in safety, and the environmental burden is reduced.

Application Information:

About Putting on the glass cap and a stainless cap
When you put the moisture getter sheet to glass cap and a stainless cap, the bubble must not enter between the surface of cap and the moisture getter sheet.
The bonding power decreases greatly when the bubble enters.

Especially, for the glass cap, there is slightly ruggedness on the surface. This causes the bubble. We recommend the putting method are not vertical putting but the roller putting in them of driving out the bubble. The figure below shows the case
