Lcd projector
LCD projectors contain three LCD glass panels that modulate red, green, and blue light from a lamp to produce colored images. The light passes through dichroic mirrors and LCD panels, which can open or close pixels to allow light through. This modulated light is then recombined and projected through a lens onto a screen. Key components include a lamp, LCD panels, lens, control panel and cooling fan. LCD projectors allow many people to view presentations, produce sharp images efficiently, and generate large images at low cost. However, they may require dark rooms and maintenance.
How does a projector works
Projectors work by using different technologies to project images or video onto a screen. The main types are CRT, LCD, DLP, and LCOS. CRT projectors use electron guns and phosphors to create images. LCD projectors use backlights and liquid crystal panels to control light transmission for each pixel. DLP projectors use an array of microscopic mirrors to rapidly reflect light and form images. LCOS projectors are similar to LCD but use reflective silicon backplanes instead of glass for better image quality. All projector types work by precisely controlling light to reproduce colors and create projected pictures.

Projector's
There are several types of projectors that can be used for presentations or entertainment. A front projection projector is good for large audiences but makes interaction difficult. A rear projection TV projects an image through lenses and mirrors to create a large screen image in a shallow depth. CRT projectors use small color CRT tubes to focus and enlarge the image onto the screen, while LCD projectors send light through a prism to separate colors and display the image. DLP projectors use a digital micro-mirror device to project images. The brightness level in lumens is an important factor, as is the throw distance between the projector and screen. Projector lamps are a key component that transfers the image to the larger screen.
Digital light processing
DLP (Digital Light Processing) technology was developed by Texas Instruments in 1987. It uses a digital micromirror device (DMD) chip containing a grid of hundreds of thousands of tiny tilting mirrors to produce high-quality images with high brightness and contrast. Each mirror represents one pixel and rapidly tilts between on and off positions to reflect light and produce colors using a spinning color wheel. DLP has advantages over other display technologies as it can create images of any size, has excellent brightness uniformity, and does not use heat-sensitive organic materials. It is widely used in projectors, TVs, and other applications demanding superior visuals.
Explaining the meaning of common projector terminology
This document defines common projector terminology, explaining terms like ANSI lumens, aspect ratio, resolution, throw distance, and zoom ratio. It is intended to help those new to projectors understand how to choose the right projector for their needs. Key terms defined include ANSI lumens for measuring brightness, aspect ratios for screen dimensions, and resolution standards for image quality. Throw distance and zoom ratio are also explained in regards to projecting images at varying sizes.
