Microdisplays and Sensors

The Microdisplays and Sensors business unit is involved with R&D on comprehensive prototypes and systems of OLED-based microdisplay and sensor components. We offer you the entire spectrum of product development for OLED-on-silicon applications, ranging from CMOS design, to OLED stack alignment, optical design, system integration, and interface programming.

Our services encompass all of the necessary steps – from the concept phase of development projects to transfer of the technology:

• feasibility studies
• conception of R&D projects including work packages, milestones, and costing
• OLED fabrication technologies for organic semiconductors
• CMOS design for controlling the OLED image or sensor devices
• prototyping
• organizing fabrication through a network of external foundries
• creation of the system design based on novel integrated circuit packaging technologies
• development of processes and procedures for fabricating structured, application-specific OLEDs, such as OLED microstructures and OLEDs for medical applications as well as for organic photodiodes (OPDs)
• pilot fabrication
• Evaluation kits for individual tests, assessments etc.
  
• technology and design transfer as well as licensing for OLED microdisplays, OPDs, augmented-reality (AR) for wearables, optical sensors, fingerprint sensors, etc.

Rigid substrate like silicon wafers or glass as well as flexible substrates can always be employed.

• bi-directional OLED microdisplays
  • in data glasses for improved human-machine interaction
  • as a display element in wearables
  • as an aid for visually impaired people
    
  • for work support in industrial fabrication, logistics, etc.
  • as fingerprint sensors
• OLED microdisplays that emiting in the visible and NIR region
• customer-specific display resolutions SVGA, XGA, VGA, …
• ultralow-power microdisplays
  • for fitness trackers
  • for monitoring vital parameters in medical applications, etc.…

In our division Microdisplays and Sensors we offer our clients a broad range of processes in a clean room environment for conducting R&D as well as pilot-scale production of OLED microdisplays and sensors.

Our work focuses on the fabrication of micro- to nanoscale thin films and their structuring. Various facilities and processes are available for this purpose. There are also analytical methods available for characterizing layers.

• combinability of different processes
• thin-film encapsulation
• deposition of high-precision layers and layer systems on wafers with positioning accuracy of ±10 µm
• wafer encapsulation processes with positioning accuracy of ±1µm
• thin-film deposition, structuring, and analysis at wafer level (200 mm)
• 300 m² clean room (class 10)
  
• pilot line for OLED-on-CMOS
• pilot line for rigid substrates
• pilot line for rigid/flexible substrates
• facilities for etching, sputtering, and spin-coating
• deposition using thermal evaporation, electron beam, Vitex/Barix™, and thin-film encapsulation
• automated wafer-bonding system
• photolithography
• ellipsometer
• wafer prober
