  • Patent number: 10468472
    Abstract: In a micro-device integration process, a donor substrate is provided on which to conduct the initial manufacturing and pixelation steps to define the micro devices, including functional, e.g. light emitting layers, sandwiched between top and bottom conductive layers. The micro-devices are then transferred to a system substrate for finalizing and electronic control integration. The transfer may be facilitated by various means, including providing a continuous light emitting functional layer, breakable anchors on the donor substrates, temporary intermediate substrates enabling a thermal transfer technique, or temporary intermediate substrates with a breakable substrate bonding layer.

  • Patent number: 10304364
    Abstract: What is disclosed are structures and methods for testing and repairing emissive display systems. Systems are tested with use of temporary electrodes which allow operation of the system during testing and are removed afterward. Systems are repaired after identification of defective devices with use of redundant switching from defective devices to functional devices provided on repair contact pads.

  • Patent number: 10134803
    Abstract: Post-processing steps for integrating of micro devices into system (receiver) substrate or improving the performance of the micro devices after transfer. Post processing steps for additional structures such as reflective layers, fillers, black matrix or other layers may be used to improve the out coupling or confining of the generated LED light. Dielectric and metallic layers may be used to integrate an electro-optical thin film device into the system substrate with transferred micro devices. Color conversion layers may be integrated into the system substrate to create different outputs from the micro devices.
