About me
55
• 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
Career highlights
56
• 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
Light Blue Optics (LBO) – phase-only projector
57
LBO – technical highlights
58
• 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– 5m 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
Pixtronix / Qualcomm – 7” MEMS / IGZO panel
59
Pixtronix – technical highlights (1)
60
• 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)
Pixtronix – technical highlights (2)
61
• 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
Nanolumens
Current research interests
63
• 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

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.”

How might Displays improve in the 21st Century?
• Infinite Field of View.
• Ever present, but only when we want them.
• Create depth in a transparent display that is indistinguishable from reality.
• Generate black in a transparent display.
• Image resolution in transparent displays making them indistinguishable from reality.
