OTI Lumionics Announces Breakthrough in Next Gen Mobile Displays

OTI Lumionics, a leader in the development of advanced materials for OLED displays, today announces the latest version of ConducTorr™ Cathode Patterning Material (CPM) is ready for mass production and will start shipping to display customers in Q4 2020 for use in next generation mobile devices with under display camera and face unlock.

With the increasing consumer demand for mobile devices with larger screens and smaller bezels, device manufacturers are looking for innovative solutions to make the display partially transparent so they can move the front facing camera and 3D facial recognition sensors (i.e., face unlock) under the display to eliminate having to make a notch or cut-out in the display.

“The challenge in making under display camera and face unlock work is that the cathode layer, a thin layer of metal that covers the entire surface of the display, absorbs a lot of light, particularly in the wavelength range required for the face unlock sensors to function. Our ConducTorr™ CPM materials are the only mass production-ready solution to pattern microscopic holes in the cathode to let enough light through for the under display camera and face unlock to function well.”

Michael Helander, Co-Founder and CEO of OTI Lumionics

OTI has been developing its ConducTorr™ CPM solution for cathode patterning in conjunction with the industry’s leading mobile device and display manufacturers and is now bringing its latest version to market. OTI recently received a strategic investment from LG Technology Ventures, the venture capital arm of LG Corporation, which will be used to help accelerate the commercial adoption of OTI’s materials in mass production.

In additional to using ConducTorr™ CPM to enable under display cameras and face unlock, OTI’s customers are also using the technology to help enable other mobile device advances:

  • Transparent displays for augmented reality (AR)
  • Larger displays for laptops, tablets and foldable devices
  • Higher brightness displays with longer battery life 

The first mobile devices using OTI’s CPM materials are expected to ship in 2021.

“Under display cameras and other applications of transparent display technology have all seen tremendous interest from mobile device manufacturers in the past few years. “Our goal is to work closely with our customers to bring the next generation of exciting mobile devices using these technologies to market faster.”

OTI will be presenting how ConducTorr™ CPM is being used to enable under display cameras and other mobile advances at two sessions at the SID Technical Symposium and SID/DSCC Business Conference during Display Week 2020.
