Researchers from the Korean Inha University developed a new method to produce shadow masks that could lead to masks that have higher densities and are also more robust - leading to higher yields in OLED production. The team are going to transfer the technology to a company that will commercialize it.

The researchers used an electrochemical processing technique to manufacture the new masks. This enables masks that are stronger (and thus fail less often) and still reach pixel densities of up to 500 PPI.

A couple of months ago it was reported that Japan's Athene also developed a new shadow mask specifically for high precision OLED production. Athene's mask is also said to be stronger and more durable than current masks used in production today.
