reflective super twisted nematic-liquid crystal display (STN-LCD) panels
with enhanced white-color quality, from the second quarter of this year.

The company made the upgrade mainly by improving the transmittance of
filters for red, green and blue (RGB), company officials said.
Also, Hitachi achieved a high contrast rating of 12:1 through the optimization
of the products' cell structure and optical system, and through improvements
of materials for spacers, company officials said.
The products have a reflectance of 25 percent, the officials noted.
The electronics company will market a 3.6-in. panel (9cm diagonal) with
320 x 240 pixels and a 6.2-in. panel (16cm diagonal) with 640 x 240
pixels.
Hitachi will aim to develop products with a contrast of 15:1 and a reflectance
of 30 percent by improving the cell structure and materials for liquid
crystals as early as the third quarter, company officials said.
