July 20013D – LCD Yossi Appelbaum 3D – LCD Post Pc Computing

July 20013D – LCD Yossi Appelbaum Basic Structure Stacked clear LCD’s Image is accepted in 3D by ‘slicing’ the original picture

July 20013D – LCD Yossi Appelbaum Main Applications Medical use - Ultrasound imaging, etc. Geographical usage – GPS map displays Games

July 20013D – LCD Yossi Appelbaum Other 3D technologies (I) Stereoscopic systems - such as 3D cinema (special glasses are needed)

July 20013D – LCD Yossi Appelbaum Other 3D technologies (II) Micro lens array over an LCD (Philips) 3D-LCD cross section 3D-LCD pixel projection

July 20013D – LCD Yossi Appelbaum Stacked LCD advantages More than one person at a given moment Almost unlimited viewing angles Ease of use (no glasses needed) No limited distance of viewing

July 20013D – LCD Yossi Appelbaum Potential Disadvantages Low horizontal resolution caused by the structure of multiple layers Back light necessary

July 20013D – LCD Yossi Appelbaum Technology Status Clear LCD’s Processing unit capable of handling multiple screens Back light 3D picture computation methods and tools

July 20013D – LCD Yossi Appelbaum Predicted Difficulties in Development (I) LCD alignment in stack: 1. Polarizing filter alignment

July 20013D – LCD Yossi Appelbaum LCD alignment in stack: 2. Color filters alignment (for color displays) Predicted Difficulties in Development (II)

July 20013D – LCD Yossi Appelbaum Predicted Difficulties in Development (III) Heat distribution – at least 50% of the light is absorbed in the display

July 20013D – LCD Yossi Appelbaum Size *Power Consumption – for a single LCD 2’’ – 3.9’’55mW – 92mW 6.5’’ – 10’’0.8W – 1.52W Power Consumption Option - Save power by refreshing the screen only when needed. * SHARP – off the shelf LCD’s

July 20013D – LCD Yossi Appelbaum Price Estimate – Market Demand

July 20013D – LCD Yossi Appelbaum Price Estimate (II) 15’’ LCD monitor: August 1999 – under $1100 By December 2001 – under $500 Suppose a 10 layer 3D-LCD = approx. $5000

July 20013D – LCD Yossi Appelbaum Next Steps Build a simple B&W prototype, and study it Study the needs of a human eye for 3D vision: 1. Depth resolution 2. Moving objects – refresh rate in 3D 3. Layer structure (overlapping images) Proceed with a color prototype

July 20013D – LCD Yossi Appelbaum There is only one problem… The 3D-LCD is physically impossible!!!
