Webinar presentation Edward Buckley March 2016
About me • Dr. Edward Buckley • Born London, England • Education – University College London (1997-2001) • MEng. Electrical and Electronic Engineering • First class with Honours – Cambridge University (2003-2006) • Ph.D. Computer Generated Holography for Displays and Sensors • Sponsored by BAE Systems • Arsenal season ticket holder 55
Career highlights • Have taken two novel display technologies from lab bench to product revenue • Recognized expert in display technologies, optics and image processing with 50 publications and 17 patents • Invented Light Blue Optics’ holographic projection technology and span out business from the University of Cambridge, raising $45m VC funding • Created ecosystem and supply chain to support laser projection business; created automotive, defense and aerospace business from scratch • Architected Pixtronix’ ground -breaking DMS display (entire architecture including color processing, backlight, backplane and power saving techniques) • Drove DMS technology through $175m acquisition by Qualcomm and eventual production and use in a 7” tablet PC 56
Light Blue Optics (LBO) – phase-only projector 57
LBO – technical highlights • Novel architecture and hologram generation algorithm to exploit HVS properties and hence reduce required calculation by six orders of magnitude • Highly novel optical system and projection lens assembly – At the time, delivered lowest speckle contrast of all laser projectors • Developed custom FLCOS microdisplay 5 m pixels, high tilt FLC material, binary modulation – • Laser development programs – Green laser (808nm pump diode) – Green laser (1064nm pump DBR) – 642nm red laser development • 8 million gate 90nm ASIC • Two Asian ODMs making complete subsystems 58
Pixtronix / Qualcomm – 7” MEMS / IGZO panel 59
Pixtronix – technical highlights (1) • DMS RGB field-sequential technology was extremely constrained – Critical image and power consumption quality problems, all counter-opposing – Yield issues made these problems even worse (achievable bit depth was low, for example) • Developed two generations of display architecture: – Generation 1: RGB, scalar dither, multiple display modes – Generation 2: RGBW multi-primary, vector dither, local tone correction, 50% power of Gen. 1 • Solved critical image quality problems – Rigorous modeling, simulation and optimization program – Color breakup, false contouring, dither artifacts, 30 Hz / 60 Hz flicker – Completely novel panel drive and image processing chain • Solved critical power problems – Novel FSC dimming algorithms (Generation 1) – Artifact-free RGBW mode, real-time gamut mapping (Generation 2) 60
Pixtronix – technical highlights (2) • Designed display architecture to provide maximum flexibility – MEMS and TFT reliability issues were never fully solved – Display architectures anticipated this and provided variable bit depth, display timing, etc. to ease yield and fabrication constraints – Accurate LED control over dimming range, even with relatively wide binning • Designed and implemented two novel color pipelines in 40 nm ASICs – HW and ARM core embedded SW • Production of 7” “Momiji” tablet – Four different display modes (wide gamut, narrow gamut, monochrome) – Interface to Android host • Improved yield by an order of magnitude – Perception-led analysis to determine allowable cluster size of flickering pixels – Dark pixel correction to hide particulate defects 61
Nanolumens
Current research interests • Multi-primary displays – Resolving FSC artifacts, enhancing image quality • Display modeling, simulation and characterization – Perceptually accurate measurements, benchmarking, competitive analysis • Halftoning and dithering – Aggressively reducing bit depth while maintaining image quality • Wide dynamic range, backlight control and local tone correction – Focus on efficient chipset implementations • Novel light sources for lower cost / enhanced efficiency – 405nm blue lasers, phosphors, OLEDs • Gamut mapping – Techniques for large and small gamuts (RGB LEDs enable both) • Subpixel rendering 63

A Vision for the Future • “The summation of human experience is being expanded at a prodigious rate, and the means we use for threading through the consequent maze to the momentarily important item is the same as we used in the days of square- rigged ships.” • “The hope is that, in not too many years, human brains and computing machines will be coupled together very tightly, and that the resulting partnerships will think as no human brain has ever thought and process data in a way not approached by the information-handling machines we know today.”
