Ultrahigh Definition Microdisplay (UDM)

Ostendo is pleased to propose the development of an emissive microdisplay that is based on a novel device called the Quantum Photonic Imager (QPI). The QPI is a highly innovative, highly disruptive optoelectronics technology; featuring high optical efficiency, high resolution, exceptional luminance and cost-effectiveness (see Figure 1). The QPI device 5ìm is estimated to be able to generate more than 70ìlm/pixel using less than 2ìW/pixel with parametric cost of less than $40 for a monochrome device having (3840x2048) pixels in high volume. A prototype monochrome QPI device having XGA (1024x768) pixels is currently being developed by Ostendo and, under funding from DARPA, is being incorporated into a 9.4 Mpx Emissive Micro-Display (EMD) to be used as a light modulator in a dynamic holography display. BENEFIT: Ostendo''s SBIR Phase I goal is to modify the current design of our monochrome QPI device currently being developed for DARPA EMD program, to reduce its pixel pitch from its current value of 10ìm to 5ìm and to increase its current XGA resolution of (1024x768) pixels to the required UDM resolution of (3840x2048) pixels. The current QPI design already meets the 12-bits dynamic range and up to 120 Hz frame rate. The Phase I Final Report will describe in detail the required QPI design modifications required to achieve this objective and will also describe the design provisions dictated by the opto-mechanical requirements of the UDM system. The QPI is a semiconductor device comprising a rectangular array of digitally addressable pixels. Each pixel would typically consist of a vertical stack of multiple solid state light (SSL) diodes, either laser diode (LD) or light emitting diode (LED), each of which generates light of a different color primary. Although the QPI device currently being developed and proposed as a baseline for this effort is monochrome, Ostendo is already working on the development of 10ìm pixel pitch RGB QPI device. Ostendo’s RGB plans can be viewed as a pre-planned product improvement (P3I) of the monochrome QPI device proposed for this SBIR effort.
