GENERAL FEATURES

The Firefly™ P350 is a full-color compact LCD projection system that is used to display a computerized multi-media presentation. The built-in amplifier/speakers lets you connect to a wireless microphone, portable CD player, or to the auxiliary output of a stereo system. The P350 also allows you to connect to the output of a VCR or LaserDisc player.

The P350 is equipped with a monitor interface connector. This allows you to simultaneously view your computer video on both the small and large screens. Figure 1 shows the P350 in use to project computer-generated images onto a large screen.

The Firefly™ P350 can be connected to any IBM or IBM compatible computer equipped with a VGA/SVGA video output. The P350 can also be connected to any Apple Macintosh computer that is equipped with a standard Macintosh video output.

The Firefly™ P350 uses advanced thin-film-transistor liquid crystal display (TFT LCD) technology and is capable of displaying up to 16,194,277 colors. The fast response time of the P350’s TFT LCD provides you with the ability to display sharp, clear, fast-moving images.

The P350 liquid crystal display is a matrix of 1.44 million pixels arranged in 600 rows x 800 columns x 3 colors. Each pixel is a single thin-film-transistor that actively controls the brightness of the light that passes through the pixel.

To protect the P350 from excessive heat, it is equipped with several cooling fans. One of these fans is running whenever the P350 is plugged in, the other fans are turned on whenever the LCD notebook projector is turned on.

The keypanel and on-screen controls allow you to change the video source, color, tint, focus, position, etc. of the projected color image; and change the volume and tone of the sound.
