| The use of two lamp system increases brightness and eliminates the need to interrupt a presentation if a lamp burns out (in dual lamp operation mode). |

| Panasonic's original liquid-cooling system directly cools the DLP™ chip, which extends PT-DW5100/DW5100L/D5700/D5700L/D4000 performance and attains a high level of reliability. It also enables operation in temperatures up to 113°F/45°C for use in a wider variety of environments, and maintains a more stable performance even in harsh conditions while keeping the operating sound down to a quiet 29 dB*. |

| The effect of dust has been minimized by completely sealing the optical block.The dust-free design helps ensure that this DLP™ projector will continue to deliver crisp, sharp, high-resolution images over an extended service life. |

| Newly developed AC lamps with full 275*1 watts of power offer excellent brightness and greater reliability than other types. A new lamp drive system also lowers the stress on the lamp electrodes while the lamps are lit. The new lamps have a lifetime of approximately 3,000 hours*2, which is reassuring for applications where the projector is frequently used. The AC lamps also minimize color irregularities. |

A filter in the air intake section traps dust particles that are 10 microns* or larger. By capturing approximately 7 times as much dust as conventional filters, it guards against optical blocks and reduces the penetration of dust into the interior to provide
stable operation by, for example, preventing drops in brightness. |

| * 10-micron dust = lint, pollen, etc. |
