There are two types of projectors: The two types of projectors are LCD and DLP.

LCD:
LCD stands for Liquid Crystal Display. The way this places an image on a screen is fascinating and not nearly as complex as you might imagine. A bulb is set up to shine a fairly powerful light through a prism. The prism splits the light into its component colors and these are sent through small LCD screens. The screens themselves are sent signals to allow just so much of the light through at specific pixel locations. The light is then beamed through a lens onto a screen where the images can be seen by the human eye.

DLP:
DLP, or Digital Light Processing is a bit more complex. This time the light is shined through a spinning color wheel onto a chip that is mounted with hundreds of thousands of tiny mirrors. The mirrors are turned off or on by electronic impulses according to the need for the color at that moment. Even though only one color is shown at a time, one color follows another so quickly that the primary colors seem to blend into the appropriate color. The image appears to be constantly lit, when in fact small parts of it are constantly flickering. This technology was developed by Texas Instruments and is based on an older technology that was used for color television in the 1950s.

What is a projector?

A projector simply projects images onto a wall or projection screen. Projectors are typically used to increase the image size for viewing by audiences. Projectors come in a variety of sizes, normally measured in Lumens which is the brightness of the light. This brightness will determine the size the image can project and the distance the projector can be from the screen. Slide projectors use light to project images from 35mm slides. Digital Projectors use light to project images from computers and DVD players.

What are profile projectors?

Also known as an optical comparator, or even called a shadowgraph, a profile projector is an optical instrument that can be used for measuring. It is a useful item in a small parts machine shop or production line for the quality control inspection team. The projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to examine or measure. This projection screen displays the profile of the specimen and is magnified for better ease of calculating linear measurements. An edge of the specimen to examine may be lined up with the grid on the screen. From there, simple measurements may be taken for distances to other points. This is being done on a magnified profile of the specimen. It can be simpler as well as reduce errors by measuring on the magnified projection screen of a profile projector. The typical method for lighting is by diascopic illumination, which is lighting from behind. This type of lighting is also called transmitted illumination when the specimen is translucent and light can pass through it. If the specimen is opaque, then the light will not go through it, but will form a profile of the specimen. Measuring of the sample can be done on the projection screen. A profile projector may also have episcopic illumination which is light shining from above. This useful in displaying bores or internal areas that may need to be measured. If you have a need for a profile projector or optical comparator, please contact us today. We have several lines available, including versions with manual micrometers or newer versions with digital readouts and digital micrometers for accurate and fast microscope measuring.

What is multimedia projector its working and types?

regarding throw of image these can be divided into three classes i.e medium range, short throw(st)and ultra short throw (ust) and regarding working it has two basic types i.e 3lcd and dlp. 3lcd is good (4-5 hr) for continuous prolong work, with comparatively poor resolution, whereas dlp provide high resolution but meant for short use i.e 45-60 min than rest needed coz it dont have fan cooling system (answer by shahid jamal) shahidjb@gmail.com

Explain working of VCR vcd audio CD player and lcd projector?

VCD player has a few main components: 1) CD reader (any cheap CD-ROM drive will do, 1X is all required) 2) a decoder (in embedded firmware) to decode MPEG stream to video 3) a video graphic circuitry with audio and TV-OUT All these are controlled by a little micro processor. The CD reader read the MPEG stream from the CD media, the microcontroller then decode that stream to put data in a video buffer which is display by the video graphic circuitry.

LED projectors use the light harnessed by individual laser diodes to create the light that is usually created through a standard type of bulb or lamp.

Why wont your s video cable work between your projector and tv?

Your TV is unlikely to have a S-Video output to go to the projector. What most TV's had was a S-Video input, to come from a Super VHS VCR or older generation gaming console. If indeed the TV has a S-Video OUTPUT, and the projector is set to the correct input (usually this has to be changed in the input menu) and you are still not getting any picture, I would check the S-Video cable for bent pins. The cable's pins are very thin and can easily be bent or broken off with rough handling.
