Physical foundations and limitations of displays including colour

The author presents short tutorial overviews on selected topics in display-relevant areas: some aspects of human vision are dealt with, the foundations and limitations of thin-film electroluminescent devices including colour are discussed as a brief example for technological and physical constraints, and basic aspects of flat-panel matrix addressing are addressed. Also discussed are the implications of human visual factors for the design of high-definition television (HDTV) displays. The author argues that the traditional direct-view CRT will not be able to meet the HDTV display screen size requirements-such a tube would be completely unpractical in terms of size, weight, and cost. The only possible solutions are flat panels of some type or projection displays. >
