PLASMA DISPLAY PANEL (PDP) DAEWOO D I G I T A L 2002. 5 DIGITAL TV DEVISION DAEWOO ELECTRONICS CO., LTD WHAT IS PLASMA DISPLAY PANEL? 1. PDP refers to plasma display panel. It was named as PDP by the faculty of University of Illinois(UIUC) as they first made it. It was made by combining physical phenomenon called 'plasma' and electric device into a form of panel.Generally speaking, plasma refers to ionized gas. However, it means 'glow discharge' in PDP business. 2. In the past, PDP was monochromatic(orange), nowadays it can generate full color by glow discharge in the 'excited spaces'.(UV from excited spaces react with fluorescent materials which then emit visible rays) 3. PDP let us watch figures or letters through image process and digital&analogue driving circuits. In PDP, material science and high technique are combined together. 4. In 1927, a plasma display panel was applied to TV rather than CRT. and its concept was established. In 1964, AC PDP was made by University of Illinois for the first time. In early1970's, George Dick invented 'surface type discharge' which is mainly used for current AC PDP. From early 1990' s, many companies have developed the AC PDP that can be selled in consumer market. 1 < The Principle of PDP> 1. The plasma display panel(PDP) can be thought of as a descendant of the neon lamp. 2. The term plasma refers to a gas that consists of electrons, positively charged particles known as ions, and neutral particles. 3. The PDP has sometimes been referred to as a gas-discharged display because it operates by passing electricity through neon gas, causing it to become 'charged' temporarily : light is produced when the gas spontaneously discharges. 4. Plasma display panels can also be viewed as a series of fluorescent lamps. The displays operate at high voltages, low currents, and low temperatures, resulting in long operating lifetimes (typical 15000 hours, max 30000 hours). 5.Inside the plasma panel, as series of red, green, and blue cells are grouped in a precise matrix.These cells are activated individually, unlike standard CRTs or LCDs, this means that they emit light individually creating a precise pixel on the viewing area. 2 < The Structure and Principle of AC-PDP > (Front Glass Substrate) Bus Electrode Sustain Electrode Protection Layer(MgO) Dielectric Layer (Back Glass Substrate) Barrier Rib Visible Light Dielec
