PT-LC75E/LC55E

Full-Featured, High-Performance Go-Anywhere LCD Projectors

Bright 1200 ANSI Lumens, High 400:1

Contrast Ratio

The PT-LC75E and PT-LC55E deliver super-bright per- formance with 1200 ANSI lumens, thanks to a newly- designed, high-performance optical system and high- efficiency 160-W UHM™ lamp. The high contrast ratio of 400:1 ensures that images are sharp, crisp, and easy to see. Both models also provide excellent bright- ness uniformity of 90%.

Excellent	Colour	Rendition
The use of advanced			10-bit digital gamma correction
circuitry with the latest algorithm gives the
PT-LC75E and PT-LC55E naturally vivid, uniform
colours and smooth image gradation. Plus, full compati-
bility with	the “	sRGB	” standard colour space	adds more
accurate colour reproduction to your presentations. The
PT-LC75E also delivers outstanding moving pictures
thanks to a	Digital Cinema Reality			(DCR) circuit and
3-dimensional comb filter			*. * For	NTSC signals only

One-Touch	Auto Setup — Ready in	Just
1.5 Seconds
The One-Touch Auto Setup function with digital key-
stone correction saves adjustment hassles. Panasonic’s
original	built-in gravity sensor	determines the projec-
tor’s angle relative to the floor (up to 30 degrees) and
corrects for keystone distortion accordingly. This makes
set-up super-easy: Just aim the projector at the screen
and press the Auto Setup button. The projector handles
all picture adjustments, from phasing and dot clocks to
vertical and horizontal position. Our newly designed
algorithm slashes set-up time to just		1.5 seconds — half
the time of	our previous models.

The One-Touch Auto Setup function features digital keystone correction with a built-in gravity sensor.

Extra Short-Throw Lens

The PT-LC75E and PT-LC55E are equipped with a large-diameter, extra short-throw lens that shortens the necessary projection distance by 25%. Conventional projectors often have to be positioned in the middle of the meeting table, with considerable distance between the lens and the screen. The shorter projection distance of the PT-LC75E and PT-LC75E saves space. For

instance, 2.4 m or less is needed to project an 80-inch diagonal screen, allowing the projector to be placed at

the front of the table. This convenient feature enables

comfortable presentations with large, easy-to-see images even in small rooms.

Quiet Cooling Fans — Only 30	dB
Whisper-quiet fans and switchable dual-mode operation
combine to reduce operating noise to 30 dB (in stanard
lamp power mode). A newly developed exhaust fan also
minimises light leakage.
Accepts Up to Two RGB Inputs and One
RGB Output
Two RGB inputs eliminate the need to re-connect
equipment when giving two different presentations back
to back. The RGB2 terminal can also serve as a loop-
through monitoring terminal for the RGB1 input. For
instance, an instructor in a
classroom can use this to				PC	Monitor

give a presentation on a
large screen while following

Versatile terminals

Unique Index Window

Any image in the presentation, RGB or video input, can be frozen, stored in memory, and displayed on the left side of the screen as an Index Window, while the dis- play of subsequent images continues on the right. This can make presentations much easier to understand.

3,000-Hour Lamp Life

The user can select from Standard and High lamp power modes. Designed for use in dark rooms, Standard mode uses a lower lamp power that minimis- es energy consumption and lengthens the lamp life up

to 3,000 hours (2,000 hours in high lamp power mode).

Note: Brightness is reduced 25% in Low mode.

The sRGB Standard

Colour Space

sRGB is a new standard that assures uniform colour expression among scanners, monitors, pro- jectors and other imaging equipment. Applying the sRGB standard minimises hue deviations to ensure the same high level of colour reproduction in each device.
