Apart from being some of the brightest yet energy efficient projectors on the market, LCD projectors also are cost-efficient and reliable – LCD technology is used in a wide range of applications today, including HDTV, mobile phones, computer monitors, and gaming devices.Click to see full answer. Similarly one may ask, what are the uses of LCD projector? LCD projector An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. Metal-halide lamps are used because they output an ideal color temperature and a broad spectrum of color. Also, how do LCD projectors work? LCD projectors work by using three liquid crystal panels, a lamp, a prism, and filters to create the image on the screen. The lamp provides white light that passes through a polarizing filter. All other light will be blocked. From the polarizing filter the light is then passed through a series of dichroic mirrors. Subsequently, question is, where are projectors used? A projector is an optical device that projects a figure or picture onto a surface. This surface is usually light in color and it may be a projection screen, white screen or sometimes a wall. Projectors may be used as an alternative to a television or monitor in large gatherings.Is DLP or LCD better for projectors?While LCD projectors have a sharper image and superior picture quality, DLP projectors are lighter, portable, and considered to be more reliable. DLP (Digital Light Processing) technology uses micro-mirrors to project images from a monitor onto a large screen.
