GENERAL DESCRIPTIONS

FEATURES

Digital Light Processing T M (DLP TM) by Texas Instruments

P503DL is a projection unit using the Texas Instruments’ Digital Mirror Device (DMD) T M optical element. The DLP TM, Digital Light Processing TM engine is constructed with the DMD chip, with XGA resolution.

Input capability

From PC video output card, SVGA signal is best suitable but some others are also compatible. Incoming PC signal timing should be followed the VESA standard.

SVGA signal is reproduced on screen without having any scaling function.

The other frequencies are converted to XGA resolution inside the cube. See note 1.

In case of SXGA resolution such as 1280x1024, an original aspect ration of 5:4 is changed to DLP aspect ratio of 4:3 so that picture may have different shape in this resolution.

Internal magnification

A multi-screen system can be formed easily with an internal magnification up to x6 magnification.

Superior image quality

*Native resolution of XGA, 1024 x 768 pixels

*No burn-in unlike projection tube

*High Contrast image by 12-degree mirror flip Double Data Rate DMD chip

Easy installation and maintenance

*Convergence free between colors

*Steady geometric alignment

*Engine installed at factory

Easy replacement 10,000/6000 H (Survival rate of 50%) UHP 100/120W selectable lamp power, See note 2

Low power consumption

100W UHP lamp is used for light source, ballast power selection of 100W/120W is possible. Total power consumption is less than 200W.

Highly reliable control system

Projection system can be controlled with a PC via RS232C cable. Also most of the control/adjustment is possible to do with optional wired remote control, CT-90000.

RS232C IN/OUT are equipped to send command and also for communication between cubes.

Mechanical function

Screen escutcheon can be removed from front. The mullion size is 1.0mm. When adjacent cube is attached, total mullion size becomes 2.5mm including gap in between.

Note 1: This does not mean that all the signals are accepted. For acceptable signals, refer to the later page in Acceptable Signal Type and also Acceptable RGB input Signal Timing.

Note 2: The lamp is expected to last more than 8000H, with the recent information, it will be more than 10000H, with survival rate of 50% at 100W power selection, however, the actual life of each lamp varies depending on conditions of use. For warranty and exchange of lamp, please check with your dealer/distributor.
