1. June 30, 2007APCU1 Displays It’s a big market: $52G I’ll talk about some of the things I’ve seen and learned this year

2. June 30, 2007APCU2 Nothing earthshaking, but lots of improvements and tweaks. Displays are getting better and less expensive. Improvements: brightness contrast efficiency general appearance Commercial problems

3. June 30, 2007APCU3 Projectors More compact, performance improving They’re thin, but thicker than flat panels; it will take some fancy marketing to sell them. Light sources: LEDs, laser diodes (LDs) Improved life and color, lower lifetime cost Cooler

4. June 30, 2007APCU4 Very small laser projectors Cigarette-pack size, battery operable Only 10-20 lumens: perhaps 2-ft diagonal Who needs them? More convenient than clustering around the laptop Very portable Might be incorporated into a cell-phone-like toy— the pPhone as competitor to the iPhone

5. June 30, 2007APCU5 The Philips response to the challenge: Ujoy Small, 50-W arc lamp with integral reflector; nice package. 200-300 lumens; enough for 3-ft diagonal in reasonable room light Small projector; could be battery operated Price ~$500 in really large volumes This could be disruptive

6. June 30, 2007APCU6 Other uses for laser projectors Head-up displays on windshields Really large displays but what about safety? UV projector and fluorescent screen

7. June 30, 2007APCU7 Improved contrast and dynamic range Backlight manipulation: change the local backlight to conform to the picture Can dramatically improve picture quality Source material? New kinds of cameras? Can also be used to save power Several approaches, both hardware and software

8. June 30, 2007APCU8 The importance of small displays Big unit volumes and dollar volume Different requirements than big displays Shorter lifetimes Variety of ambient illuminations Power requirements Emissive, reflective, transflective Touch input (also for big displays)

9. June 30, 2007APCU9 Electronic paper Reflective Bistable (most types), hence very low power Low speed generally OK Technologies: electrophoretic Bistable LCD Electrowetting, magnetic balls, others Limited gray scale and color (so far)

10. June 30, 2007APCU10 Electronic paper continued) Applications: Electronic books Signage Shelf labels Flexible displays

11. June 30, 2007APCU11 3D Techniques: eyeglasses Autostereoscopic Immersion “Real” 3D displays Applications Problems Cinema may be a big market

12. June 30, 2007APCU12 Quick review of technologies LCDs PDPs OLEDs Organic transistors, transparent transistors LEDs (big displays) FEDs New technologies and their commercial problems

13. June 30, 2007APCU13 Conclusion Prices will continue to fall and electronic displays will become even more pervasive Ebooks and flexible displays will begin to be commercially available—the foldaway ebook Inexpensive head-mounted displays will happen— eventually It’s great fun to watch!
