連續顏色處理（FSC）液晶電視及螢幕

Abstract

The objective of this report is to supply technologists, managers, product planners, engineers, researchers and marketing personnel with the information needed to evaluate field-sequential LCD technology for large screen applications such as laptop computers, desktop monitors and LCD-TV. FSC systems have been demonstrated at technical conferences such as SID but further development is still necessary. This report will not only outline the current state of the technology, but will indicate which areas of FSC LCD technology need additional work before product design can begin.

• Overview of existing large screen LCD technology
• Elements of current LCD technology that will carry forward into FSC systems
• Technical requirements for FSC systems
• Backlight technology for FSC
• Liquid crystal effects that have sufficient speed to support FSC displays
• Development roadmap for FSC displays
• View the complete table of contents

This report contains 19 figures and 7 tables.

• This report should be purchased by anyone involved in research, development or design large screen LCD panels.
• The report is of value to people planning large screen LCD products.
• Component suppliers to the LCD panel and set manufacturers who need to understand the future trends in the market.
  • Backlight manufacturers
  • Solid-state lighting suppliers
  • Suppliers of the LCD drive electronics
