Versaperm Vapour Permeability measurement

The Curse of Water for LED screens and optoelectronics

The Curse of Water for LED screens and optoelectronics

Damage caused by water vapour and oxygen are the curse of OLEDs, LEDs, optoelectronics and flexible screens.  These devices are extremely sensitive to vapour damage and protection from them is vital if they are to continue working. 

To alleviate the curse of damage demands the use of specialised multi-layered barrier coatings, usually with alternating organic and inorganic layers.  The extreme sensitivity of modern flexible, curved or standard screens and optoelectronic devices to water and oxygen means that the vapour permeability of every layer and structure must be determined and controlled – and that’s where Versaperm comes in. 

Versaperm has developed specific techniques and instrumentation for measuring materials, layers and coatings both individually and as compound structures.  It can determine both water vapour and oxygen permeability, in fact any mixture of vapours can have its separate components determined separately from just one overall measurement.

The system can also detect and characterize the pinholes that are almost invariably produced during the manufacture of these protective barriers.

Versaperm offers an advanced, fast and efficient way to test and measure vapour permeability of new barrier films and sealants. The system is easy to use, fast and extremely accurate.

Results are typically accurate in the Parts Per Million (PPM) to PPB range and can be produced for several samples, screens or enclosures at the same time.  It can measure them under a wide range of environmental conditions.
