Arisawa, Seiko, TI, JVC to jointly promote microdisplay TVs

Arisawa Mfg. Co. Ltd, Seiko Epson Corp., Texas Instruments Inc. (TI) and JVC have collaborated to establish the Micro Device Display Consortium (MDDPC), to promote the features and advantages of microdevice display projection TVs (MDDP).

The consortium aims to promote the growth of MDDPs and boost public awareness of the technology. In addition to the founding members, 3M Company, Luminus Devices Inc., Samsung Japan Corp., and SCRAM Technologies Inc. have joined the consortium as endorsing members.

Microdisplay devices includes technologies such as DLP micro mirror device supplied by TI, liquid crystal on silicon devices including D-ILA promoted by JVC, and high temperature polysilicon devices supplied by Epson and Sony Corp. Images from these microdisplays, measuring 0.5 to 0.9 inches in size, are projected to screens measuring 40 to 70 inches in diagonal.

Formation of the consortium could help kick-start the microdisplay market, which according to some analysts faces increasing competition from plasma displays. Last December, makers of plasma displays formed the Plasma Display Coalition to market plasma displays.

U.S. key market
One target area for the consortium's activities will be the United States, a major market for rear projection TVs.

"Technology for rear projection TVs is shifting from CRT to microdisplay devices. Rear projection TV sets are selling well there, but dealers and consumers do not necessarily understand what microdisplay devices are. At a glance, people often mistakenly mix up rear projection TVs with flat-panel TVs," said Shintaro Nakagaki, associate director and general manager of display unit at JVC's technology development division.

Consortium members noted microdisplay-based TVs offer low power consumption, low cost, light weight, high resolution, and low energy consumption. Power consumption is 200W on an average per set in the 40 to 70-inch range. It does not vary according to the size of the TV, as the light source is the same 100-watt class lamp. A microdisplay-based TV consumes one-third the power of a plasma or LCD set for a 60-inch model.

Founders of MDDPC agreed that it was necessary to enlighten people about the advantages of the MDDP. The consortium will prepare marketing materials for its members to share in promoting the common advantages of MDDP. In addition, the consortium will launch a website to provide information on MDDP and product demonstrations are also slated.
