  2. Outline • What is television? • Television Types • Mechanical television introduction • Electronic television introduction • Configuration of CRT • Color television introduction • Cathode Ray Tube • TFT-LCD introduction • WHAT IS PLASMA？ • PDP Basic Structure • AC-PDP The basic light emitting principle and structure • Comparing Figure • Application

  3. What is television? • Continuous, dynamic image and sound is converted to electrical signals and transmit electronic signals through various channels, and then the electronic signal restored image and sound technology. • Means to receive this electronic signaling device, which can receive and restore the electronic signal is active, a continuous means of images and sound, commonly referred to TV. 影片網址:http://www.youtube.com/watch?v=PRcdr1A-cgQ

  4. Television Types Mechanical television Electronic television tradition color television television LCD television Modern Plasma television

  5. Mechanical television Paul Gottlieb Nipkow

  6. Electronic television Valdimir Zworykin

  7. CRT consists of 6 sections: • Glass bulb evacuated to a high vacuum • Cathode (a source of electrons) • Cathode heater • Electrodes for brightness and focus control, several accelerating anodes • Pairs of horizontal and vertical capacitor plates deviating the electron beam • Fluorescing screen Configuration of CRT
