Q. What's the 3D Technology in Theaters?
- Most common approach is to project both Left & Right imagessimultaneously on screen.
- Each image is polarized in the opposite direction, eyeglass's lenses are plarized accordingly so that each eye sees the intended image.
- 3D effect is realized in the viewers brain when it putstogether two images with slightly different perspectives.
Q. What are the Components of 3D in Theaters?
- Projector that displays 2 different images on screen simultaneously (digital or film)
- Ploarizing lens in front of projector
- Metallized screen to preserve polarization
- Polarized glasses for viewer
Q. Will 3D be available to the consumer via Flat Panel (FP) or Front Projector (FP)?
- Both Flat Panel & Front Projector approaches will be available.
Q. What types of 3D technology will be available for Flat Panels?
2 distinct methods: Active vs Passive
- Active method
- Frame sequential & Active shutter glasses
- Display: Left & Right images shown sequentially at very high speed
- Glasses: Active shutter glasses synchronize with screen so each eye sees intended image.
- Display must communicate with glasses
- Polarizing film built into the front of flat panel screen & Passive polarized glasses
- Polarize odd/even lines in opposite way
- Simple Polarized lense glasses
Q. What are the advantages & disadvantages of Active method?
- Pro - Full HD resolution
- Pro - Cost on display side is minimal
- Con - Active shutter glasses
Q. What are the advantages & disadvantages of Passive method?
- Pro - Inexpensive glasses
- Con - Cost goes into display
- Con - May compromise 2D picture quality?
Q. What are the advantages & disadvantages of flat panel technologies?
- LCD Pro - High brightness
- LCD Con - Limited viewing angle
- Plasma Pro - Smooth motion
- Plasma Con - Low brightness
Q. What types of 3D technology will be available for home Projectors?
2 methods: Theater approach vs flat panel approach
- Theater approach
- 2 projector/engine & metal screen & polarized glasses
- Display both Left & Right images simultaneously
- Flat panel approach
- 1 projector & standard screen & active shutter glasses
- Frame sequential display of Left & Right image at high rate
Q. What are the advantages & disadvantages of 1 vs 2 projectors/engines?
- 1 Pro - Cost for 1 projector
- 1 Con - Active shutter glasses
- 2 Pro - Inexpensive glasses
- 2 Con - Up to double the cost
- 2 Con - Difficult to calibrate
- 2 Con - Need Metallized screen (retrofit issue)
Q. What do I need for 3D at home?
- 3D capable display
- 3D capable source (3D BD player/ PS3 / cable box)
- 3D capable AV receiver with 3D signle pass through
- High Speed HDMI cables
- 3D content (Blu-ray disc, PS3 game, broadcast from cable/satellite
- Eventually 3D content via IP connection
Q. Do I need to purchase a new TV panel/projector to watch 3D content?
- In most cases yes, a panel/projector will require a significant ammount of video processing 'horse power (to properly display 3D content).
- Also, for an active 3D system, the TV panel/projector must transmit a signalto the active glasses.
Q. Do I need HDMI 1.4 cables to watch 3D?
- No, any HDMI cable that can handle 10.2 Gbps (340MHz). HDMI 1.3 High Speed cable has sufficeint bandwith to support 3D content. The cable must be High Speed rated.
Q. Can a 3D display show 2D content?
- Yes, display remote will have a button to switch from 2D to 3D.
Q. Will all 3D disks display OK on any 3D system?
- Yes, manufactures have agreed on the required 3D standards. So any 3D source signal will display OK.
Q. Will a display from manufacturer X work with a blue ray player from manufacturer Y?
- Yes, manufactures have agreed on required 3D standards.
