3D Viewing Points vs. 3D Method Method Merit Technical complement Image selection method Without Glass Glass Multi-tasking possible Less bothersome than glasses Viewable from multiple positions and angles Less 3D cross talk. Viewing point selected by viewing position such as distance and angle. Left or right image is selected by glass (polarization /color/timing) Number of Viewing Points 2 points Easy to use( Light system) Multi view Image data is light. Easy to real time processing Wide viewing Angle Minimize data to stereo image Easy to take movie/picture, to generate computer graphics and transfer data Need multiple view points data Decrease the resolution Prorate viewing data. 22

Conventional 3D-LCD Viewing 3D images achieved via parallax component Difference in what the left and right eyes see 2D 3D Right Eye Left Eye Right Eye Left Eye Optical Lens / Barrier Pixels Left and right eyes can see all pixel data Left view Pixel Right view pixel Left and Right eyes can see respective Left and right data Key issues with conventional 3D technology 1) 3D resolution is half of 2D 2) 2D image lacks continuity when using Optical Lens/Barrier 25
Features of NEC's 2D/3D-LCD HDDP (Horizontally Double- Density Pixel) unique and suitable design for 2D/3D Focus on high performance 3D imaging to personal use. HDDP design R-R R-L G-R G-L B-R B-L Conventional Design (Horizontally Double-Density Pixel) Same pixel pitch in 2D and 3D mode Very high 3D viewability 3D images can be seen easily and without eye fatigue The same resolution in 2D and 3D display. 2D and 3D mixed images are easily displayed at the same time 2D and 3D mixed images 26
Comparison 3D Technologies Resolution * Horizontally Double-Density Pixels Conventional Design HDDP* Panel Design Lenticular Lens 3D Image Pitch: Conventional = double HDDP = same 2D Image Pixel Pitch: Both same Pitch 27
2D/3D Mixed Image Using HDDP Technology 2D and 3D images can be simultaneously displayed by changing the input image data => Easy to mix 2D and 3D images 3D Image 2D Image Right-Eye Pixel Left-Eye Pixel Right-Eye Pixel Left-Eye Pixel Right-Eye Data Left-Eye Data Same Data 28
NEC s High Performance 3D Issue with conventional 3D: Moire can occur from optical combination between LCD Panel and parallax lens / barrier. Conventional 3D technology Moire occurs NEC s HDDP 3D: Optimize LCD panel and parallax lens / barrier, No Moire! NEC s HDDP No Moire 29
3D crosstalk [%] NEC s High Performance 3D Issue with conventional 3D: Minimum area of 3D crosstalk is very narrow 3D cross-talk between right eye data and left eye data is large NEC s HDDP 3D: Reduce 3D cross-talk to minimum Expand minimum area Natural and Real 3D 100 Left Right 10 1-20 -15-10 -5 0 5 10 15 20 Angle [degree] 30
