Sony Corporation Annual Report 1997
Plasmatron Flat Display Panels
In December 1996, the company began taking
orders in Japan for color TVs that incorporate
a 25-inch Plasmatron flat display panel, which
boasts high brightness and contrast. This TV
has a monitor section only 13.2 centimeters
thick. Its brightness, high contrast, and slender
profile are all the result of plasma address
liquid crystal (PALC) technology, which Sony
developed with U.S.-based Tektronix Inc.
PALC technology uses a plasma discharge to
switch the LCD elements on and off. Plasma is
an electrical discharge phenomenon caused
by applying an electrical voltage to a low-
pressure gas. This mechanism vastly simplifies
the structure of the display, enabling the fabri-
cation of large-scale screens. Through a PALC
technology sharing agreement with Sharp
Corporation, a company renowned for its
expertise in LCD technology, Sony plans to
develop a 40-inch-class Plasmatron flat dis-
play panel with high contrast and a wide
viewing angle by the fall of 1997.
Wide-screen televisions incorporating the Super Flat Trinitron CRT, which is flat over its entire surface, generate text,
multi-screen images, and other pictures without distortion. The simulated picture shows a scene from Sony Pictures
Entertainment’s hit film
Jumanji
.
This PerfecTV! digital
satellite broadcast
reception system has
a versatile program
guide for checking out
upcoming shows on
the service’s more
than 70 channels.
