  3. 平面顯示器 • 電漿 (Plasma) • 背投 (Rear Projection) • 液晶穿透式 • 微機電反射式 • 矽上液晶反射式 • 液晶 (LCD)  LCD TV 是未來的明星工業

  4. 兩兆雙星

  5. Subject • Picture • Sound • Connection • Information • Reception • Multimedia function

  6. Picture Quality Factors • Brightness • Contrast • Color • Sharpness • Viewing Angle • Response Time • Uniformity • Jaggy • Jerky

  7. A Typical Picture Specification • Screen Size : 30" (76 cm) • Visible Screen Size : 75 cm (29,53”) • Display : LCD WXGA Active Matrix TFT technology • Resolution 1280x768 (x3) pixels • Response time LCD : 16 ms • Brightness : 450 cd/m2 • Contrast Ratio : 350:1 • Viewing Angles : 176H/176V • Anti Reflex Coated Screen

  8. Brightness More backlight

  9. Contrast Whiter and blacker

  10. Gamma Correction  The detail of black and white field

  11. Color - cross color Cross-color

  12. Color – flesh tone correction Too healthy

  13. Color – white balance & color temperature Black Body Locus 5300K 6500K 9300K

  14. Color Temperature Normal Warm Cool

  15. Sharpness More clear edge

  16. Viewing Angle Good Lower contrast, color Bad

  17. Response Time Tailing

  18. Uniformity Mura

  19. Jaggy

  20. Jerky – 3:2 pull-down Artifact Film mode Video mode

  21. Jerky – motion blur

  22. Panel Technology: IPS vs MVA Source: JPMorgan estimates, December 2003

  23. PQ Decision Weighting in LCD TV CONTROL TUNER IR/KBD RF STEREO DECODER AUDIO PROC IF NTSC PAL SECAM IF DATA PROC SIF CVBS YUV CVBS LUMA PROC De-int.

  24. Subject • Picture • Sound • Connection • Information • Reception • Multimedia function

  25. A Typical Audio Specification Example • Sound Power • 20 W RMS • 40 W Music Power • 4 On Board Speakers • Separate Headphone • Audio line output • Optical SPDIF output • AC-3 in HDTV broadcasting • Dolby Virtual (surrounding process)

  26. Virtual Surrounding Process • Good sound can improve visual effect • An auxiliary selling point: • SRS • BBE • Virtual Dolby

  27. Some Real Surrounding Technology • Dolby Pro Logic • Dolby Digital • DTS • THX Surround EX / Dolby Digital EX

  28. Subject • Picture • Sound • Connection • Information • Reception • Multimedia function

  29. RF connections • NTSC (F-connector) • PAL/SECAM (IEC connector)

  30. Analog video connections • CVBS • S-video • YPbPr/YCbCr • SCART • EIA-J D • D1-D5 • D-sub  HD support: 480P/1080I/720P Japan D formats D1: 480I D2: 480P D3: 1080I D4: 720P D5: 1080P

  31. Digital video connections • DVI • DVI-I • DVI-D • DVI-A • HDCP (High-speed Data Content Protection) • 1394 • HDMI

  32. Audio connections • Baseband audio • RED: Right channel • WHITE: Left channel • Sub-woofer • Digital audio • Coaxial • Optical

  33. Standard Connections CVBS/S-video YPbPr CVBS/S-video YPbPr(HD)

  34. Subject • Picture • Sound • Connection • Information • Reception • Multimedia function

  35. Closed Caption • Allows the viewer to read TV program dialogue or voice conversations as on screen text

  36. V-chip • A program content advisory data • Respond to the advisory data by blocking content that the viewer finds objectionable • FCC approved a program rating system in March 1998 • All new TV sets (13 inches and larger) sold within US should have it by January 2000 CC/V-chip  For the US, Canada, and Brazil

  37. Teletext tele - text • It is a format to transmit data within a video signal • Data rate is a few MBit/s • Accepted global standard (WST) • Secure delivery data channel • Data error checking • Low cost • Uni-directional  From 1 page to 1,000 pages

  38. Teletext Pages

  39. Subject • Picture • Sound • Connection • Information • Reception • Multimedia function

  40. TV Color Systems 1. NTSC M NTSC-J NTSC 4.43 2. PAL I D B, B1, G, H N M Nc 3. SECAM D, K, K1, L B, G
