Understanding Projector Technology
Before we dive into the evaluation process, it’s essential to understand the basics of projector technology. There are three primary types of projectors: LCD (Liquid Crystal Display), DLP (Digital Light Processing), and LCoS (Liquid Crystal on Silicon). Each technology has its strengths and weaknesses, which we’ll discuss briefly.
LCD projectors use a liquid crystal display to block or allow light to pass through a matrix of pixels. They’re known for their high brightness, good color accuracy, and relatively low cost. However, they can suffer from a lower contrast ratio and may exhibit a “screen door effect” due to the pixel structure.
DLP projectors, on the other hand, use a digital micromirror device (DMD) to reflect light onto the screen. They’re praised for their high contrast ratio, fast response time, and ability to produce deep blacks. However, they can be more expensive than LCD projectors and may exhibit a “rainbow effect” due to the color wheel.
LCoS projectors use a liquid crystal layer on top of a silicon substrate to block or allow light to pass through. They’re known for their high contrast ratio, good color accuracy, and fast response time. However, they can be more expensive than LCD projectors and may suffer from a lower brightness.
