  12. How Does It Work?

  13. How Does It Work? Glass Substrate Transparent Electrode Phosphor Layer Bus-Electrode BarrierRib Dielectric Layer Dielectric Layer MgO Thin Film Glass Substrate Address Electrode

  14. Front panel bus electrode dielectric ITO electrode MgO layer barrier address electrode Back panel phosphors How Does it Work? • Put the Gas(He/Ne/Xe) in the vacuum space to be shut tight with the front and back glass • The gas discharged if it makes Volt at the electrode • UVU is made and generates the visible light the fluorescent substance through.

  15. Address(Data) Drivers X-electrode Y-electrode (Scan Drivers) ③ SCAN (2nd line addressing) ④ SCAN (3rd line addressing) ⑨ SCAN (8th line addressing) ⑦ SCAN (6th line addressing) ⑧ SCAN (7th line addressing) ⑤ SCAN (4th line addressing) ⑥ SCAN (5th line addressing) ② SCAN (1st line addressing) ① Ramp를 이용한 RESET 방전 ⑫ Ramp를 이용한 RESET 방전 ⑩ 전면 SUSTAIN 방전 (Vs<Vf) ⑪ 벽전하 제거 ERASE 동작 How Does It Work? Switch = FET

  17. How Does it Work? • Sub Field 3 action made of Reset, Address, Sustain Reset Address Sustain • Function • Sustain Erase • Wall Charge Set • Issue • Operation margin • Contrast • Short Time • Function • Select On Cell • Issue • High Speed • Low Voltage • Low Failure • Function • Discharge On Cell • Issue • High Efficiency • Low Voltage • ERC Performance

  20. Circuit Panel • Excution/Logic • - circuit design, • Optimization. • Logic Algorithm • - Wave shape/Screen • Material Tech. • - Elctrode, Phosphors • Dielctric. • Process Tech. • - Ventilation, Aging Discharge • Discharge wave shape • - Design Tech. Discharge efficiency - Cell structure, Gas System Architecture PDP = Panel + Circuit + Electric discharge • Panel : [Material + Process] + Discharge efficiency • Circuit : [Excution/Logic Circuit + Logic Algorithm] • + Discharge wave shape

  21. System Architecture • Drive – Take the logic signal and transmit at Drive IC • Logic – Take the image signal and control bus electrode and • address electrode to fuction Panel. • SMPS – Provide the need electricity at an each board (AC/DC, DC/DC) SMPS Y_main X_main Y X Logic Logic Logic buffer [Basic Structure of PDP]

  23. PDP, Well-being Display

  24. PDP : Characteristic is similar with CRT • LCD : Don't do the bright adjustment according to the screen area The truth of the bright It is really good if it is just bright ? PDP:To be bright changes according to the screen area →Natural comfortable at the eye intensity. LCD: Always high bright without the relation of the screen area → The eye is tired if it sees continuously. Bright characteristic Bright (cd/m2) 600 LCD Peak Bright 500 LCD Avg. Bright 400 300 CRT Bright • Need natural intensity expression • to reduce the fatigue of the eye. • Shining impression needs • to maintain at least PDP Peak Bright 200 CRT Avg. Bright 100 PDP Avg. Bright 0 25% 50% 75% 100% white screen area ( Source: 大阪교육대학 인간행동학과 高橋 誠 교수 연구, 2005)

  25. High resolution in the dynamic screen Operate originally to the half less of the resolution in the LCD TV dynamic screen • LCD TV : Operation to less than SD resolution in the Full HD dynamic • screen. • PDP TV : Original resolution hold in the dynamic screen PDP (1280×768) LCD (1920×1080) Slowly (8sec/ screen width) HD resolution SD resolution • Move the picture according • to speed and observe to • a high capacity camera on • the screen • Movement in left to right Fast a little ( 4sec/S.W.) Less than SD resolution Almost HD resolution (Source: FPD International, 2005)

  26. After watch LCD -> Sleepy/faint impression is relatively big After watch PDP -> Difference does not exist The fatigue of the eye after we watch LCD TV is more big→ The fatigue of the eye ; LCD > PDP → The fatigue of the eye increases especially in the 50 years olds ~ 60 years olds PDP Vs. LCD for Humans eyes 1. The fatigue of the eye Result of the mental state assessment ○The number change to twinkle the eye ○ Change of an impression 130% LCD 180% 120% 100% LCD 100% 50+60代 20代 100% PDP PDP Instability Tired Sleepy Displasement Faint Before watch During watch After watch

  27. LCD : The eye sight degradation while we watch TV is happened. - The eye sight recovery after rest. → The burden of the eye about LCD is big PDP : The eye sight degradation does not exist almost ○Eye sight change for the 100 minute +0.05 PDP 0 -0.05 LCD -0.1 Watch TV for 100 minute -0.15 Rest Eye sight degradation 25minute -0.2 Before watch 1st watch 2nd watch 3rd watch 4th watch After rest PDP Vs. LCD for Humans eyes 2. The eye sight degradation The eye sight change.

  28. Next generation technique district

  29. Cost • Low volt drive • method • Low cost Filter • Simple circuit • structure • Low cost panel • material Low consumption electricity • Low consumption : • 100W • Next genetation • discharge structure Next generation PDP tecnique Screen Quality & FHD • 13bits image processing • Enhenced Bright room • contrast • 40” FHD • False Contourfree

  30. Bright level Bright level Input level input level Natural Color & Gray Scale Enhenced gray scale output and Noise reduction 14Bit image processing technology+ Error Diffusion 14 Bit image processing = CRT Like <12 Bit: 4096> <14 Bit: 16384 > Error Diffusion

  31. Enhanced Contrast Lower Reflection Technology Panel + Filter Enhenced Panel Enhenced Filter [Glass Filter] [Film Filter]

  32. A1 A2 A1 A2 A3 Y1 X Y2 X Y3 X Conventional New - SDI 50FHD (New Cell structure) Y1 X Y2 X FHD New structure which the electric discharge is possible in small space SDI New structure = Electric discharge space extension + DATA elctrode reduction • Electric discharge space extention • - 6% space extention (50FHD) • - 42”FHD Possible • DATA elctrode reduction : 35%

  33. 1.1us Key point of Full HD is Cost • High Speed Data Processing • - HIgh speed Scan time : Conventional 1.96us → New 1.1us • - High speed Data processing : Conventional 67.4MHz → New 148.5MHz • ※ FHD S/Scan : New execution method development need • Need FHD panel technique (0.5 p) • - Present structure impossible → Need new structure development Conventional Full HD <Scan time> <High Speed Scan time> 1.96us

  34. Low consumption electricity New discharge structure Innovative structure development • Surface discharge → Nonsurface discharge • → Space discharge • Negative Glow discharge • → Positive Column discharge • Create UV without discharge Efficiency 3 times enhance [ Equal to the consumption electricity of the 100W glow lamp] Conventional New = = ?

  35. COST Simple circuit + Reduce Driving Volt • 1st : Small Size PBA、Multi Channel Drive IC • 2nd : Reduce Driving volt 50%、Simple component • 3rd : LSIand Reduce PBA、Apply COG Tech. Next Step Present ?

  36. DTV = PDP World Only 1, No.1 Display • Big Screen • FHD • High quality • screen Industry • CRT Like Cost HDTV Replacement CRT, PJT · Natural color · Reality · Size 37”~102” · All FHD
