Capability profile
CPM cathode patterning and transparent OLED materials
CPM is OTI's material-enabled process for controlling thin-film growth through self-assembly. Patterning the top OLED electrode creates transparent openings between pixels for near-infrared sensors and cameras and can improve transparent-display construction. OTI reports validation on customers' production lines; DNP has collaborated on compatible evaporation masks and cleaning processes. Defence relevance is an integration hypothesis for displays and sensor modules, subject to configuration-specific testing.
OLED materials and manufacturing process
What it enables
Core features
- Self-assembly patterning of deposited thin films, including the top cathode electrode.
- Microscopic openings between pixels allow near-infrared signals to pass through the display.
- OTI reports patternable electrode sheet resistance below 1 ohm per square.
- OTI reports a 17-inch transparent AMOLED demonstration with 65 percent transmission, fabricated on an ITRI Gen 2 pilot line.
- DNP evaporation-mask deposition and cleaning work targets compatibility with existing OLED manufacturing equipment.
