| [Electronics Show '98] High-Definition, High-Luminance 42-in. PALC Displays Debut

|
October 9, 1998 (TOKYO) -- Sharp Corp., Sony Corp. and Royal Philips
Electronics NV of the Netherlands jointly developed a 42-in., high-definition
display and a 42-in. high-luminance plasma-addressed liquid-crystal
(PALC) display.

The products are on exhibit at the Electronics Show '98 held in Osaka,
Japan, Oct. 6-10.
PALC is a technology for large-screen displays that combines technologies
in plasma-display panels (PDPs) and liquid-crystal displays (LCDs).
The high-definition type has 1,920 x 960 pixels, as compared to previous
products with 854 x 480 pixels.
Sharp said the product can meet the image quality needed for high-definition
television (HDTV). That high definition was realized by modifying its
discharge control system and developing new color filters.
The high-luminance type has increased its luminance by as much as 1.5
times that of previous products to 400 cd/m2 without increasing
its power consumption. To realize that high luminance, its transmittance
was increased by optimizing its cell structure, and the aperture ratio
was increased by modifying the design of barrier ribs.
