Do away with work-sheets: you can now engage students with presentations, interactive games, video content and group activities all in one session. Each element of your lesson can be pre-planned on a laptop, and for simple presentations, you can just insert your USB drive directly into the projector.

Description

LCD projectors have also 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.
