Shinoda Plasma Corp developed a 125-inch curved-surface display using its proprietary PTA (plasma tube array) display technology.

The screen measures 3 x 1m connecting three 1 x 1m PTA sub-modules sideways. It has 960 x 360 resolution and uses 600W at maximum. The display part is as slim as 1mm, and the weight is no more than about 3.6kg.

The company prototyped an 86-inch display using 1 x 0.5m PTA sub-modules Oct 26, 2007 (See related article 1). It is planning to start mass-producing the 1 x 1m PTA sub-module prototyped this time in October 2008.

The new prototype is "nearly as good as a mass-produced model," said Tsutae Shinoda, president and chairman of Shinoda Plasma. He continued, "There are already some users who want to purchase it given its current display performance (for digital signage and such applications)," showing his confidence in the prototype.

The company also presented its 43-inch prototype revealed in the special session of "CEATEC Japan 2007" in October 2007 (See related article 2). Compared with the 43-inch model, the 125-inch prototype features higher display performance.

Although the PTA structure itself was not changed, "We've improved the manufacturing process to achieve even luminance," Shinoda said. The tone display and some other operational conditions were also changed, he said.

However, Shinoda intends to further enhance the display performance, saying that PTA technology is currently "at about 60 to 70% of its potential. Its current display performance is close to that of PDPs in 1999 to 2000."

The company is planning to conduct a private presentation of the 125-inch curved surface display in conjunction with the "InfoComm 08" event, which will take place in Las Vegas from June 14 to 20, 2008. The private presentation is scheduled for June 18 to 20, 2008. The company will install a filter to prevent reflections, while further improving operational conditions at the presentation, it said.

Final product to be co-developed with Hibino

Shinoda Plasma also announced that it formed an alliance with Hibino Corp for the development and sale of its PTA-based final product. The two companies will co-develop the final product combining Shinoda Plasma's PTA module and Hibino's video processor. They will gradually strengthen their alliance in view of partnership in marketing and capital, they said.

"We are considering forming alliances with two to three other manufacturers in Japan toward the commercialization of the display" from now, Shinoda said.

Shinoda Plasma has already formed alliances with Ulvac Inc, Fujimori Kogyo Co Ltd and Dyden Corp concerning the manufacture of PTA modules (See related article 3).
