Panasonic PT-D5500E/EL manual High Image Quality, High Reliability and Easy Maintenance

High Image Quality

Ultra Bright 5,000 Lumens

A single-chip DLPTM design, liquid-cooling system and dual-lamp optical system team up to achieve a brightness of 5,000 lumens.

This enables bright, large-screen projection even in well-lit condition.

Number of Lamp	Lamp mode	Brightness
		Normal Lamp	Long Life Lamp
Dual	High	5,000 lm	2,500 lm
	Low	4,000 lm
Single	High	2,500 lm	1,250 lm
	Low	2,000 lm

High 1,600:1 Contrast Ratio

This high-contrast combines with an outstanding brightness for crisp, high-resolution images in virtually any viewing environment. Contrast can be switched between High and Normal as conditions require.

Contrast Mode	Constrast	Brightness
		Normal Lamp	Long Life Lamp
High	1,600:1	2,500 lm	1,250 lm
Low	800:1	5,000 lm	2,500 lm

Under Dual lamp condition

High Uniformity of Brightness and Colour

The PT-D5500E/EL's outstanding brightness and contrast ratio assures high uniformity of brightness and colour, resulting in vivid and natural image.

Progressive Cinema Scan (3/2 Pulldown)

This interlace/progressive conversion technology automatically detects when the input signal is derived from filmed material and selects the optimum progressive processing method to assure faithful reproduction of

the original image.

Dynamic Sharpness Control

The Dynamic Sharpness Control circuit adjusts the video signal waveforms based on the difference in brightness of adjacent pixels for a sharp,

clear picture that is relatively unaffected by signal noise.

High Reliability and Easy Maintenance

Liquid Cooling System

Panasonic's newly developed liquid-cooling system directly cools

the DMD chip, which extends the PT-D5500E/EL's performance and attains a high level of reliability.

Dustproof Design with Sealed Optical Block

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

Dual Lamp System and Lamp Relay Function

The use of two lamp systems increases brightness and eliminates the need to interrupt a presentation if a lamp burns out (in dual lamp operation mode). In single lamp operation mode, the lamp relay function greatly extends continuous operating time.

Optional Long-Life Lamp

A long-life lamp that stretches lamp life to 4,000 hours is available as an option. In single lamp operation mode, the lamp relay function allows non-stop operation 24 hours a day for up to 47 weeks without replacing the lamps.

The use of UHM lamps dramatically cuts operating costs.

Easy Replacement of Dust Filter and Lamp

Dust filter is replaced from the side and lamps are replaced from

the back panel.

Both of them are replaced

very easily even if PT-D5500E/EL is installed.

Flexible System Applications

Lens-Centred Design

A lens-centred, symmetrical design provides flexible system layout, eliminating the need for any special considerations when planning the installation site.
