Applications

• For education use, Before projectors became so common in the classroom, teachers would have to get into class early to write up notes, and constantly erase and rewrite content on the board as the lesson progressed. These regular disruptions often caused students to lose interest, or start chatting among themselves as they waited for the next part of the lesson. Then, more time would be wasted on classroom management.

  Now, you can plan presentations and exercises in advance, use them for multiple student groups, and share them with other teachers. This greatly reduces the admin burden, and makes it easier to stay organised — both inside the classroom and out.

• For business use, Since most companies operate on a pretty tight financial plan, getting rid of this extra cost is quite an attractive option for business owners to consider. Despite the initial outlay for equipment this will soon be recouped from saving on paper and ink and increased productivity. our installation teams would keep any disruption to minimum most projector installation can be completed in one day more complex jobs would take considerably longer but the benefits would out weigh any loss of the room for a day or two.

• For home use,With a projector in the house, you literally have the same type picture on a screen like in a Movie Theater. Watching a movie on a 100-inch or more screen with full surround sound in the comfort of your own house is an exhilarating experience and is for sure better than seeing a movie in a theater.

Description

LCD projectors have been around since the 1980s, and use the same liquid crystal displays that create the images in watches and other electronic devices. Specifically, most LCD projectors use 3 LCD technology, a patented system that combines three liquid crystal displays. An image is created in a multistep process, which begins with the light source providing a beam of white light. The white light is passed to three mirrors, called dichroic mirrors, that are specially shaped to reflect only a certain wavelength o flight. In this case, the mirrors reflect red, blue, and green wavelengths. Each beam of colored light is then fed to an LCD panel, which receives an electrical signal that tells it how to arrange the pixels in the display to create the image. All three LCD panels create the same image, but they have different hues because of the colored light passing through the panel. The images then combine in a prism, creating a single image with up to 16.7 million colors that is passed through the lens and projected onto the screen.
