How LCD Projectors Work The old method of film projection was simple: Each frame of the film was a tiny, translucent photograph. Shine light through the film and then have that light pass through an imaging lens and you'd display a larger version of that tiny image onto a wall or screen. LCD projectors work a little differently. A beam of high-intensity light travels through thousands of shifting pixels in an LCD display instead of through a frame of translucent film. And these projectors don't just use a single LCD display either -- they use three, which is why they're also called 3LCD projectors.

- If you are looking to buy a new projector for a classroom, meeting room or home theater, the image you project on the screen should make a great impression on your audience.Researching projectors can be confusing, with many acronyms and technological terms.he amount of brightness you need is determined by the room you project in. Projector brightness is measured in lumens. For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens.

LCD Projector Techopedia explains LCD Projector. The light source for an LCD projector is a standard lamp. An LCD projector allows the source light to pass through the three colored liquid crystal display light panels. The panels in turn allow some colors to pass through and block some colors to form the images on the screen.

Definition of a Projector Definition of a Projector. A projector is a device that uses light and lenses to take an image and project a magnified image onto a larger screen or wall. Projectors can magnify still or moving images depending on how they are built. The image must be shone through a sealed tube or frame when passing through the lenses to maintain focus.

Projector Lamps - FAQ This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness. The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about 2000 hours. The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified.

What Is the Lifetime of a Projector? Most bulbs or lamps will last for about 2,000 hours, though some projectors can be expected to last considerably longer. You can always extend the lifespan of your office's projector by taking care of it with regular maintenance.

How Do Contacts Work? Please Share! How contact lenses work to correct vision is the same way eyeglasses do: they alter the direction of light rays to focus light properly onto the retina. If you are nearsighted, light rays focus too early within your eye  they form a focus point in front of the retina instead of directly on it.

- For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens. For classrooms, conference rooms or rooms with windows, a projector with a minimum of 2500 lumens is best. For large auditoriums or lecture halls, you'll need more lumens.

How do glow sticks work? Part 2 A glow stick is a plastic tube containing a glass vial, two chemicals, and fluorescent dye. The glass vial contains phenyl oxalate and the plastic tube contains hydrogen peroxide and fluorescent dye solution. How does it work? Glow sticks are a chemical reaction formed by phenyl oxalate, hydrogen peroxide, and fluorescent dye. When you break the glass vial by bending the glow stick in half, it causes the phenyl oxalate to release into the plastic tube. When the two chemicals mix together, it causes a chemical reaction that creates energy. Then the fluorescent dye turns the energy into light.

SmartBoards or Interactive Projectors? The interactive projectors that use a pen are very interesting and we are investigating the options. Keep in mind that you have to run a usb cable to the projector to use the pen on most models. Also if you get an interactive projector that is also 3D, the pen will most likely not work when you are using the 3D.

How Television Works How Television Works. As you can see in the drawing, there's not a whole lot to a basic cathode ray tube. There is a cathode and a pair (or more) of anodes. There is the phosphor-coated screen. There is a conductive coating inside the tube to soak up the electrons that pile up at the screen-end of the tube. However, in this diagram you can see no way to steer the beam -- the beam will always land in a tiny dot right in the center of the screen. How Amazon Fire TV Works.

Digital Light Processing In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). These mirrors are so small that DMD pixel pitch may be 5.4 µm or less. Each mirror represents one or more pixels in the projected image.

- Home Theater Projector Buyer's Guide. What Is Brightness? How much illumination your eyes perceive on the screen depends on two factors: (1) the light output of the projector, and (2) the reflective properties of the screen. There are two common methods of measuring light in a home theater. One is the ANSI lumen rating of the projector. That measures the light energy being generated by the projector itself. The second is foot-Lamberts (fL), which takes the screen into account and measures the total light that is being reflected back toward the audience.
