History
IBM T221 started out as an experimental technology from the flat panel display group at IBM Thomas J. Watson Research Center. In 2000, a prototype 22.2 in TFTLCD, code-named "Bertha", was made in a joint effort between IBM Research and IBM Japan. This display had a pixel format of 3840×2400 (QUXGA-W) with 204 ppi. On 10 November 2000, IBM announced the shipment of the prototype monitors to U.S. Department of Energy's Lawrence Livermore National Laboratory in California. Later in 27 June 2001, IBM announced the production version of the monitor, known as T220. Later in November 2001, IBM announced its replacement, IBM T221. On 19 March 2002, IBM announced lowering the price of IBM T221 from US$17,999 to US$8,399. Later in 2 September 2003, IBM announced the availability of the 9503-DG5 model.
IBM and Chi Mei Group of Taiwan formed a joint venture called IDTech in 2001 to manufacture the T221 in Japan. ViewSonic and iiyama OEMed the T221 and sold it under their brand names. The production line of IDTech at Yasu was sold to Sony in 2005 and the fate of the T221 is unclear. The monitor is no longer on sale. Chi Mei has since demonstrated a 56" 3840×2160 QuadHDTV display, which was later produced as a CCFL SMVA panel under the model name V562D1.

Famous quotes containing the word history:
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“The principal office of history I take to be this: to prevent virtuous actions from being forgotten, and that evil words and deeds should fear an infamous reputation with posterity.”
—Tacitus (c. 55–c. 120)
