A projector is a device that integrates a light source, optics system, electronics and

display for the purpose of projecting an image from a computer or video device onto

a wall or screen for large image viewing.

There are hundreds of products available in the market and they are differentiated

by their resolution, performance and features. These devices attached to a computeror video device as you would connect a monitor.

Usage

- Companies, public organizations: Images on PC can be directly projected onto a

large screen without the disturbance occurring when using OHP. The projector can

be used for a variety of purposes - for meeting or presentation, and video projections

can be used for PR or training. Now we also have ultra-compact products allowing

presentation-on-the-move.

Usage

- Schools, training centers, churches: Various educational multimedia data and videos

can be directly projected onto a large screen for the purpose of education.

- Others: Enjoy movies at home, small theater or cafeteria. The projector can also be

used at exhibitions for a wide variety of purposes.

PRT type Projector

A PRT type projector adopts high-performance PRT (similar to CRT for TV) for screen projection

and is composed of 3 projection lenses. Although images are natural and clear, product size is

big and installation as well as screen adjustment is difficult. Brightness and compatibility with

PCs are also its weak points. Not used very much these days - except for A/V purpose.


6/476

A LCD type projector adopts LCD for screen display. The size is getting smaller while brightness is

improving. Owing to strong compatibility with PC, many companies, schools and public offices are

now using LCD type projectors.The LCD projector is dominating the Projector market.

Uses Texas instruments "micro-mirror arrays" -

hundreds of thousands of pivoting mirrors tomodulate the image, instead of using LCDs.

A new technology competing with LCDs,

DLP Projector using a technology from Texas

Instruments, that was brought to market 1996.

Generally, DLPs are considered to havesuperior video quality to LCDs.

DLP : Digital Light ProcessingDMD : Digital Mirror Device

DMD type Projector


8/478

Advantages :

- LCDs have a very visible "mask" or

dark area around each pixel. But DLPshave virtually no mask. In normal use,

DLPs project a virtually seamless image.

Disadvantage :

- Only TI hold patents of DLP.

So, TI supplies all DMD.

Brightness

1. What is a ANSI lumens?

40 Screen

ANSI lumen is a measure of brightness put out by a projector, as standardized by American

National Standards Institute.

Over 2,000 ANSI lumens

1000 ~ 2000 ANSI lumens

Under 1000 ANSI lumens

: You are not disturbed by interior illumination

: You can get a good image with lights dimmed,

so turning off the light is advisable.

: You can get a good image in bright condition.

2. How much brightness do I need to get a good images?

Calculating ANSI lumens(In case of 40 screen size)

1. Measure the mean illumination of 9 points on the screen likeright figure.

2. Mean illumination X area = ANSI lumens

Ex) When 40 inch (SIZE = 0.495 m2) is projected on the screen ,

The mean illumination is 2,500 lx

-> 2,500 ( lx ) x 0.495 (m2) = 1,237.5

1,237.5 ANSI lumens

Compression

Compression Technology is the ability of a projector to display higher resolution than its original.

All DMD and LCD projectors have only one real(or true)" resolution. To display higher signal, they

must "compress" the data to fit.

about 40% ofthe information

Input Output

For example, to display XGA(1024 x 768) signal, you must compress it into SVGA(800 x 600) format,

in other words, must eliminate about 40% information out of 1024 x 768(appr. 800,000 pixels) to

fit the whole screen.

Complicated algorithms are used to selectively eliminate so much data, with leaving the best

possible image.

1. What is a Keystone Correction?

Keystone Correction

Keystone function is useful when your image appears wider at the top or bottom

because the projector is positioned somewhere other than the center of thescreen. Keystone correction corrects this rectangular distortion.

Flip Horizontal Flip Vertical

Flip horizontal function reverses the left

and right side of the projected image.Use this function when a projector

shoots from behind a screen and the

screen is viewed from the opposite side.

Flip vertical function reverses the upper

and the lower side of the projectedimage

Use this function when you mount a

projector on the ceiling because the

projected image is turned upside down.

: enables you to see the hidden portion

of the images, covered by the zoomed-

Window Zoom

: enables you to enlarge a specific

portion of an image appointed bywindow.


22/4722

Auto Tracking

This function assures you of getting

the best video quality by

automatically adjusting the difference

of horizontal width and tremor of the

image. This difference is caused bydisaccord of the internal signal of the

projector and diverse graphic signals

of PC.

This function is operated only in PC

mode.

Safety operation

1. Thermal guard

This sensor checks the temperature above the lamp case.

If the temp. is high(above 80 degree) the Projector will lamp off.

2. Case open detection

If the lamp replacing cover is open, the Projector will not power on.

3. Thermo - sensorThis sensor checks the temperature above the prism.

High Temp. warning : 69 degree

High Temp. power-off : 72 degree

4. Fan abnormal detection

If the fan is out-of-order, or stopped abnormally,

the projector will lamp off.

How to upgrade the Software

1. Disassemble the top case

2. You can find the shield case in the bottom side of the main PCB

3. Short R1025, R1026 (which is near the shield case )

normally, R1025, R1026 is opened.

(1) R1025 : makes the flash memory in write-unprotected state

(2) R1026 : enables the program voltage(3.3V) to the flash memory.

4. Plug the power cable.

5. Connect the mouse cable to the PC that has the downloading software

6. Copy upgrade files(config.hex, gui.hex, romcode.hex, pixelware.inf) to

your upgrade folder which you have made.

7. Follow the instructions(Upgrade Instruction pages) of next page.

.

.

.

8. After downloading, disconnect the mouse cable and power cable.

9. Open R1025, R1026

we recommand that R1025, R1026 is in open state.

10. Assemble the top case.
