High Brightness with

High-Power AC Lamp

The high-efﬁciency light convergence

technology and the color wheel work

together to achieve the high brightness of

6,000 lm for the PT-DZ680/DW640 and

6,500 lm for the PT-DX610. Clear, crisp

images are reproduced even in bright

rooms.

RGB Booster Signiﬁcantly Improves

Color Reproduction

The RGB Booster achieves high image

quality with levels of color reproduction and

brightness that make each color stand out. It

combines Panasonic's proprietary Vivid

Color Control technology with a newly

engineered Lamp Modulation Drive System

for a 1-chip DLP™ projector that produces

bright and vivid colors.

Vivid Color Control

This unique control technology optimizes the

use of the color segment areas of the color

wheel. It increases the brightness of each

RGB color by minimizing the unallocated

portions between the colors, to achieve truly

vivid coloring.

Lamp Modulation Drive System

With the advanced lamp modulation

technology, the projector is able to control

the lamp intensity for each of the red, green,

blue, and white segments of the color wheel

separately. Because the actual light output is

controlled in relation to each color segment,

light usage is optimized and color balance is

obtained without lowering the brightness.

This results in bright vivid images with

increased color ﬁdelity.

Lamp power

By modulating the lamp power, we can

maximize the color reproduction of each

color without sacriﬁcing brightness.

Light usage is optimized, and color

balance is obtained without lowering the

Lamp power

Because the lamp power was ﬁxed in

conventional projectors, color

reproduction was enhanced by

sacriﬁcing brightness.

Detail Clarity Processor Brings

Depth and Clarity to Detail

This advanced image-processing circuit

analyzes the video signal frequency range for

each scene by extracting data on the

distribution of high, mid, and low-frequency

components, and brings out ﬁne details

accordingly. The resulting images have a

more natural, three-dimensional appearance

with crisp, clear detail.

System Daylight View 2 for

Enhanced Color Perception

Image details are less clear when a projector

is used in a room with the lights on.

Panasonic's System Daylight View 2

improves brightness perception by adjusting

sharpness, gamma curves, and color

corrections. This produces crisper, more

stunning images with vivid colors even under

bright conditions.

DICOM Simulation Mode*

This imaging mode is similar to DICOM part

14, which is a medical imaging standard. It

reproduces X-ray images with remarkable

clarity.

Rec. 709 Mode for HDTV Projection

Optimal color reproduction can be achieved

by selecting this mode, compliant with ITU-R

Recommendation BT.709, when images

from an HDTV source are projected.

Full 10-Bit Picture Processing

(PT-DZ680 Only)

The use of a full 10-bit image processing

system provides smooth tonal expression.

For example, skin tones appear natural and

true to life.

Eco Filter that Needs No

Maintenance for up to 12,000

Hours*

The original Eco Filter consists of two Micro

Cut Filters (electrostatic ﬁlters), a pre-ﬁlter

and a main ﬁlter, which use an ion effect to

collect extremely small dust particles. The

pre-ﬁlter has a honeycomb conﬁguration and

the main ﬁlter is pleated to achieve a large

surface area that raises its dust collecting

performance. Thanks to these features, the

Eco Filter has a replacement cycle of up to

12,000 hours*

maintenance. And, as

an environmental

consideration, the

ﬁlter can be washed

with water and

Dual-Lamp System Prevents Image

Interruptions

The Dual-Lamp System eliminates the need

to interrupt a presentation if a lamp should

burn out (in dual-lamp operation mode). The

Lamp Relay mode also operates the lamps

alternately to enable 24/7 projector

operation. The replacement lamp unit*

projectors. This reduces the number

of lamp types that need to be kept in stock

when multiple projectors are used.

Liquid Cooling System Attains a

High Level of Reliability

The liquid cooling system directly cools the

DLP™ chip to improve performance and

enable operation up to 45 °C (113 °F).*

This allows use in a wider variety of

environments, while stabilizing performance

and keeping the unit quiet even in harsh

conditions.
