Introduction of Plasma Display Panel (PDP) Ching-Wei Bau

Intro. of Plasma Display Panel Introduction Display Theorem Process View Circuit View PDP vs. TFT-LCD Conclusion

Display Theorem Like fluorescent lamp (or neon) : 1.Address electrode causes gas to change to plasma state. 2. Gas in plasma state (emitting UV) reacts with phosphors in discharge region. 3. Reaction causes each subpixel to produce red, green, and blue light.

Process View Transparent electrod Improve contrast Address electrod Infuse into Ne + Xe

Circuit View

PDP vs. TFT-LCD AttributePDPTFT-LCDDirect-View CRT Size <= 36 Distortion near edge Peak brightness Level Very goodGoodBest Contrast ratioVery goodGoodBest Color fidelityExcellentLimitedBest Dynamic Performance ExcellentPoorBest Viewing angle160 degrees40-70 degrees160 degrees LifetimeExcellent (30,000 hrs) Individual pixels can fail over time Excellent

Conclusion Future Market : - USA, Taiwan: Digital TV after China: Digital TV after Europe, Japan: Not decided Job Opportunity: - Semiconductor Process - Digital Signal Process
