HITACHI AND TEXAS INSTRUMENTS ANNOUNCE AGREEMENT TO JOINTLY DEVELOP HDTV

Digital Light Processing technology chosen as basis for new all-digital multimedia display

Tokyo, Japan and Dallas, Texas -April 27th, 1999:  Hitachi, Ltd.(TSE:6501 / 
NYSE:HIT) and Texas Instruments (TI) announced today that they have signed an 
agreement under the terms of which Hitachi will use Digital Light Processing? (DLP?) 
technology to develop the world's first all-digital, large screen high definition (HD) rear 
projection television.  Hitachi plans to release the new television in Japan and the U.S. 
market in the second half of 2000.  

The agreement also calls for TI to further develop DLP technology in support of HDTV 
applications with 16:9 aspect ratio, and for the two companies to collaborate in the 
development of new, higher brightness projection optics, HDTV signal receiving 
technology and an image processing LSI (Large Scale Integrated Circuit).

The two companies will also consider extending future collaboration beyond the areas 
announced today.

 "We have been extremely impressed with the significant advances in DLP technology 
aimed at serving the Home Entertainment market," said Masao Kato,Executive Vice 
President of Digital Media operations at Hitachi. "While DLP technology has served the 
data projection market with many leading products, recent breakthroughs - focused on 
improving video performance - have elevated DLP to a new level.  It's this outstanding 
video performance that is required to satisfy the demands of Home Entertainment 
enthusiasts. This new project represents an exciting opportunity for Hitachi to bring 
innovative, premium performance products to the market:  we're delighted to have signed 
this agreement with TI today."

 "Signing this agreement with Hitachi is an extremely exciting milestone in the 
development of DLP technology," said Bob England, Senior Vice President and Manager 
of TI's Digital Imaging division.  "Hitachi's choice of  DLP for this new High Definition 
product speaks volumes about not only how much the technology has progressed, but 
also its extraordinary potential for the future. We're excited that DLP technology will 
deliver the first-ever all-digital display to the home entertainment market."

Demand for home theater systems is increasing worldwide:  digital terrestrial 
broadcasting will begin this spring in ten major cities in the U.S, with satellite high 
definition broadcasting starting during the summer.  In Japan, BS digital broadcasting 
will begin in 2000, bringing high resolution, high image quality  movie programming to 
every home. 

"Texas Instruments demonstrated a prototype of this technology at CES in January and it 
was truly awe-inspiring," said David E. Mentley, Vice President of Stanford Resources, 
Inc.  "It clearly has the potential to raise the performance bar for rear-projection HDTV 
displays." 

Hitachi has built a substantial business in the projection display market and now has a 
broad product line which includes CRT monitors for TV and PC applications, LCD-based 
projectors and displays and plasma display panels (PDPs).  In the United States, Hitachi 
has a significant share of the market for projection televisions under the UltraVision? 
brand name.  Hitachi's in-house optics technology development enables all its projection 
and display products to feature outstanding image quality.  

DLP is an enormously attractive technology for the development of next generation 
HDTV systems, based on its digital nature, its high resolution, its high contrast and the 
fact that it enables the development of uniquely small and lightweight product packaging.

Today, TI supplies DLP subsystems to more than twenty-five of the world's top projector 
manufacturers, who then design, manufacture and market DLP-based projectors.  Over 
the past three years, DLP-based projectors have consistently won some of the audio-
visual industry's most prestigious awards, including, in June 1998, an Emmy Award from 
the American Academy of Television Arts & Sciences.  Since shipments began in early 
1996, TI has delivered over 150,000 DLP subsystems to its customers.  There are now 
over fifty DLP-based products in the market.

At the heart of TI's Digital Light Processing technology is the Digital Micromirror 
Device (DMD), an optical semiconductor chip that has an array of  microscopic mirrors 
mounted on a standard logic device.  These tiny mirrors operate as optical switches to 
create a high resolution, full color image.  

Hitachi, Ltd., headquartered in Tokyo, Japan, is one of the world's leading global 
electronics companies, with fiscal 1997 (ended March 31, 1998) consolidated sales of 
8,417 billion yen ($63.8 billion*).  The company manufactures and markets a wide range 
of products, including computers, semiconductors, consumer products and power and 
industrial equipment. For more information on Hitachi, Ltd., please visit Hitachi's Web
