Second Call A plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass. During the early 60s, the University of Illinois used regular televisions as computer monitors for their in-house computer network. The inventors of plasma researched the technology as an alternative to the cathode ray tube -based televisions being used till then. By July of 1964, the team had built the first plasma display panel with one single cell. After th at, television broadcast companies considered developing plasma television as an alternative to televisions using cathode ray tubes. However, another technology was rising: LCD or liquid crystal displays made flat -screen television possible, which hindered the further commercial development of plasma displays. It took many years for plasma televisions to become successful. After more than 60 years of continuous improvements, today's plasma televisions use millions of cells and allow high resolutions on a flat screen. They display sharper contrasts and deeper blacks than LCD displays, and technological developments have increased their lifespan – which was a major drawback of Plasma displays and remains lower than the LCDs. • The S-shaped curve of Plasma technology is today higher than that of LCD technology • The S-shaped curve of Plasma technology is today lower than that of LCD technology • Looking at both curves today, we may understand the investment policy pursued on both technologies in the past • A technology manager should compare the curves per each relevant performance before taking any investment decision on the two technologies The S-Shaped curves help technology managers in understanding the evolutionary path of a technology. This means…
