The High Definition Systems program was established by the Department of Defense's Advanced Research Projects Agency, or ARPA, in 1989. ARPA initiated the program because of its commitment to the proposition that displays are more than just flat panels. The challenge was, and continues to be, creation of display systems that incorporate improvements through the merging of computation and image presentation. Such flat panel displays are, literally and figuratively, windows into today's information age. The HDS program is a true "dual use" technology program and a key element of DoD's vision of an integrated commercial and defense industrial base. The ability of the United States to equip its military with technically superior information systems depends on having a reliable supply of affordable, state-of-the-art high defmition displays. The objectives of the HDS program are two-fold: (1) to enable "information windows" to be applied to new domains by making high-defmition display systems thinner, smaller, brighter, more power efficient, more mobile, more integrated with computing and more effective in human terms and (2) to develop affordable differentiated display products for DoD systems. The result should be the necessary domestic technology and manufacturing capability to meet requirements for the 1990s and beyond.
