Hitachi will launch six PDP and five LCD TV products in series, starting in mid-August, 2005.
The PDP TVs use 55-inch, 42-inch and 37-inch panels currently being developed
by Fujitsu Hitachi Plasma Display Ltd. (FHP). The 55-inch model's resolution is
1366 x 768, while the 42-inch and 37-inch models' resolution is 1024 x 1024.
The key topic is Hitachi has achieved a peak luminance of 1,400 cd/m2 (only in
the 42-inch model), which the company claims to be "the world's highest." The
previous model only achieved a peak luminance of 1,100 cd/m2. According to a
Hitach's spokesperson, "We have drawn the panel's maximum potential by devising
the drive circuit and increasing the number of electric discharges."
Furthermore, black luminance lowered through modification in the technology
driving reserve discharge resulted in a higher contrast ratio of 3,000:1,
compared to the previous 1,000:1.
In a bid to emphasize the panels' superior features including the higher
luminance and contrast ratio, Hitachi also improved the optical filter (front
panel board) to be located in front of the panels. While boosting light
transmittance, the company designed the surface of the filter to minimum the
reflection of light radiated from fluorescent bulbs outside the TV. The optical
filter's characteristics are adjusted so they are just right to absorb the
light of 3-wavelength fluorescent bulbs. |
