Page 38: Background Information
Antares-PJ1Training Background Information Types of Projectors Slide 38 This section briefly explains the various projector technologies on the market. - Page 39 Antares-PJ1Training Types of Projectors There are 4 main types. CRT projectors: These use three cathode ray tubes (blue, green, and red). LCD projectors: These use three LCD filters to create red, green, and blue images. DLP projectors: DLP (Digital Light Processing) was developed by Texas Instruments.
- Page 40 Antares-PJ1Training CRT Projectors These use three cathode ray tubes (blue, green, and red). They have better contrast than LCD and DLP projectors. They also have good resolution. But they are bulky, heavy, and difficult to adjust. Slide 40 No additional notes...
- Page 41 Antares-PJ1Training LCD Projectors LCD projectors appeared during the early 1990s, and are now the main type of projector. Three LCDs receive electrical signals from an image- generating device. One receives signals for the red part of the image, one the green, and one the blue. In this way, each LCD holds a pattern of pixels.
- Page 42 Antares-PJ1Training DLP Projectors (1) Projector Lens DLP Chip Lens Lamp Lens Color Wheel The DLP chip is the central part of this type of projector. A DLP chip consists of many small pixel-sized mirrors laid out on a semi- conductor chip. Light shone on the DLP chip is reflected by all these tiny mirrors.
- Page 43 Antares-PJ1Training DLP Projectors (2) R, G, and B signals from the image generating device are sent to the DLP chip, and timed so that the red signal arrives at the same time that the red part of the wheel is in the beam path, and similarly for the green and blue signals.

There R, G, or B Light Polarized Light are one of these assemblies for red, green, and blue. The RGB images are sent to these semiconductors, and beams of light are reflected off...
- Page 45 Antares-PJ1Training Background Information Polarization Slide 45 No additional notes...
- Page 46 Antares-PJ1Training What is Polarization? Vertical Horizontal Component Component Light Polarization refers to the orientation of the electric field. It is convenient to think in terms of up-down (vertical), and left-right (horizontal). If the polarization is at an angle, then this polarization can be thought of as having up-down and left-right components.
- Page 47 Antares-PJ1Training Polarizing Filter In a polarizing filter, the arrangement of the molecules allows (for example) the up-down component to pass through, but not the left-right component. Think of a rope passing through a picket fence (with vertical slits). If you vibrate the rope in a horizontal direction, the fence will block the vibrations.
- Page 48 Antares-PJ1Training S- and P- Polarization P-polarized Unpolarized Light Light Plane of Incidence If the electrical field is polarized parallel to the plane of incidence (in other words, horizontal), it is said to be p- polarized. If the field is polarized perpendicularly to the plane of incidence (vertical), it is said to be s-polarized.
- Page 49 Antares-PJ1Training Polarization by Reflection Unpolarized S-polarized Light Light Reflection off certain non-metallic substances can polarize light. If the angle is correct (different for each mineral, depends on the arrangement of molecules in the mineral), the reflected light will be completely s-polarized. The refracted light will be at least partially p-polarized.

Page 51: Terms And Definitions
Antares-PJ1Training Terms and Definitions - 1 Aspect Ratio This is the ratio of the horizontal to vertical dimensions of the screen. For a normal television, the aspect vratio is 4:3. For HDTV, it is 16:9. For SXGA, it is 5:4. Resolution This is expressed as the number of dots across the image versus the number of dots down the image. - Page 52 Antares-PJ1Training Terms and Definitions - 2 Dichroic Mirror A dichroic mirror reflects light of a certain frequency range and allows all other light to pass through. LCD projectors contain two of these mirrors, to split the light up into three beams. Polarized Light Light waves oscillate in the same way as sound waves.
- Page 53 Antares-PJ1Training Terms and Definitions - 3 Air Filter Air is drawn into the projector to cool its internal components. The air filter prevents dust from being pulled into the projector with this air. If the filter becomes dirty, air cannot pass through properly, and it will become hot inside the projector.
- Page 54 Antares-PJ1Training Terms and Definitions - 4 Suspension from the Ceiling This machine can be suspended from the ceiling, if the required metal supports are fitted. These metal supports are not supplied with the projector. Changing the Lamp The first time that the power is turned on after the lamp has been used for 3000 hours, a message is displayed for the user.
- Page 55 Antares-PJ1Training Terms and Definitions - 5 Lux, Lumen, Candela The brightness of a lamp is generally measured in lumens, and ambient brightness and light reflected from a screen is generally expressed in lux. Lumen » This ANSI unit is used to measure the amount of light emitted from a light source.
- Page 56 Antares-PJ1Training Terms and Definitions - 6 Uneven colour This term is used when the contrast and color of the image is not constant. There are many possible causes for this. Gradation Between white and black, there are shades of grey. The number of levels between white and black are called gradations.
- Page 57 Antares-PJ1Training Terms and Definitions - 7 Contrast In general, this is the ratio between the bright and dark parts of an image. A high contrast gives a clear image. A projector with an internal light source is unaffected by external light sources gives a high contrast image that is clear.
- Page 58 Antares-PJ1Training Terms and Definitions - 8 Floor or table, normal projection: Image Adjustments Reverse - off, Ceiling - off If the projected image is flickering or blurred, in the wrong position, and so on, the horizontal position, vertical position, and synchronization Floor or table, reverse projection: can be adjusted.
- Page 59 Antares-PJ1Training Terms and Definitions - 9 Gamma correction This adjusts the signal level to get the correct VT response characteristics (V: input voltage, T: amount of transmitted light). Trapezoidal image correction (Keystone correction) Depending on the angle of projection, the projected image will be distorted into a trapezoidal shape, instead of a rectangular shape.
- Page 60 Antares-PJ1Training Terms and Definitions - 10 Screen Gain A measure of how brightly a screen displays an image. The higher the screen gain, the brighter the screen. Relation between Screen Gain and Brightness Generally, the larger the screen, the darker it is. If you choose a screen with a higher gain, the brightness is preserved to some extent.
- Page 61 Antares-PJ1Training Terms and Definitions - 11 Ad hoc mode and Infrastructure mode There are two ways to connect to a PC using W-LAN. Ad hoc mode is used to connect to a PC without using a W-LAN access point. Infrastructure mode is used to connect to a PC through a W-LAN access point.
