TI JAPAN TO RECEIVE PLASMA MEMORY TECHNOLOGY FROM NHK

 TI JAPAN TO RECEIVE PLASMA MEMORY TECHNOLOGY FROM NHK
 TOKYO, May 13 /PRNewswire/ -- Texas Instruments Japan Limited (TIJ)


announced today an agreement with Nippon Hoso Kyokai (NHK), in which NHK will transfer to TIJ its basic technology for gas discharge flat panel TV displays.
 Under this agreement, TIJ will develop the semiconductor integrated circuits (ICs) for driving color plasma displays. These displays will be used in flat panel displays for color television sets, including high definition television (HDTV). TIJ will also develop signal processing ICs for this application, along with the required manufacturing process.
 The devices will use a technique known as Pulse Memory Method (PMM) to drive the display. Plasma display technology will be used to create flat panel displays which are over 20 inches wide. Wall-mounted television and flat HDTV are getting more attention because of their capability to reduce the space required for large screen color televisions. Such displays are representative of the current trends in the television industry.
 Sachiaki Nagae, president of TIJ said "The flat display market will be one of the high-growth market of the 1990s. This agreement with NHK gives TI the system knowledge needed to design high voltage integrated circuit drivers for Japan's future HDTV. TI will use this technology in work with customers in Japan, Europe and America, and thus participate in markets for these displays worldwide."
 NHK is leading the development of HDTV and has become one of the world's first broadcasters to create such advanced video systems. Most of the TV manufacturers in Japan have been developing television sets that meet NHK's HDTV standard. In its early stage of development, plasma display has been well accepted in this application because of its large screen, flat panel capability. NHK has succeeded in developing 33-inch televisions that can partially display broadcasted high definition images.
 Financial details of the TI/NHK agreement were not disclosed.
 TIJ will exhibit a prototype of the plasma display panel system at the Society for Information Display (SID) Conference '92 being held in Boston starting on May 17.
 Texas Instruments Incorporated, headquartered in Dallas, is a high- technology company with sales and manufacturing operations in more than 30 countries. TI develops, manufactures and markets semiconductors, defense electronics systems, electrical controls, metallurgical materials, and consumer electronic products.
 TIJ is the largest American supplier of semiconductors to the Japanese market and is a wholly owned subsidiary of Texas Instruments Incorporated. TIJ employs approximately 5,500 people in Japan.
 Editorial Backgrounder
 Nippon Hoso Kyokai (NHK, Japan Broadcasting Corporation) NHK is the Japan's only public broadcasting organization, established in 1925 as the Japan's first radio broadcast station. NHK developed the broadcasting and receiving technical standards which form the basis for the Japan's high-definition television format known as MUSE or Hi-Vision.
 Plasma Display Panel (PDP)
 Plasma display is a type of flat video screen. Many pairs of electrodes are arranged systematically on each of two flat pieces of glass and gas is sealed between the electrodes. High voltage is applied between two electrodes creating a glow discharge that gives off light. There are two technologies, AC-PDPs and DC-PDPs. The type of panel is determined by the structure of the panel. AC-PDPs are suitable for high-luminescence with memory. However, DC-PDPs can also realize high-luminescence and large screen sizes through the use of Pulse Memory Method (PMM). The development of color DC-PDPs for HDTV have recently gained much attention.
 Pulse Memory Method (PMM)
 A method for driving DC-PDP developed by NHK. In gas discharge phenomenon, a plasma cloud of metastable atoms is generated and decreases gradually after the applied voltage is removed. It is easier to re-ignite the gas discharge if the cloud of metastable atoms still exists. PMM uses this characteristic. The display cells, once accessed and activated by the electrical pulses, glow until an erase pulse is applied. By this method, DC-PDP is given memory capability. This capability will make big and bright flat display panels a reality.
