Hitachi, Ltd. has developed Japan's first XGA-compatible 25-inch color plasma display, which can display more than 2.5 times the pixels of VGA-compatible plasma displays.

The color plasma display is a new technology that increasingly is being regarded as a way of producing large-screen color displays that are flat and light. The increased use of multimedia in the past few years is fueling a demand for higher-resolution displays.

One answer is this newly-developed XGA 25-inch color plasma display panel (color PDP), with newly-developed high-speed PDP drive circuitry using high voltage driver ICs for stable, high-resolution images. The display has multiscan capability which automatically adjusts to XGA, SVGA or VGA signals from a PC, and can also display a video signal.

The prototype display, which is aimed at the business use market, uses a 25-inch screen which is capable of simultaneously displaying an A3 page full-size with icons around the periphery. In its 1,024- by-768-pixel XGA mode the panel displays 2.36 million dots, which is more than 2.5 times the number of dots displayed in VGA mode (640 by 480 pixels). Despite its large, 25-inch (diagonal) size, the display is only 8 cm deep, weighs only about 15 kg, and provides full wide-angle visibility even in the high-resolution XGA mode. Hitachi is also working on the development of wide-screen displays of 40-inches or more for the home TV market, which is getting ready for multimedia.
