Projection is an essential but risky component in an event. Here are some tips and explanations about projectors.
Today, technology have made portable projectors lighter and less expensive, but also more powerful and functional. Many of them are multi-application devices. The formats that most event planners are used to are with LCD and DLP.
LCD (Liquid Crystal Display) relies on three mirror panels that act as a prism to project the red, green and blue lights that comprise the picture.
DLP (Digital Lighting Processing) uses a DMD chip (Digital Micromirror Device,3), where every pixel on the chip is a reflective mirror and the image is projected through a spinning colour wheel.
LCD projectors are in general slightly cheaper compared to DLP projectors.
Factors that determine the price of a projector:
– Resolution is the number of pixels displayed side to side and top to bottom on the screen. These numbers are important to know when matching devices (laptops, personal digital assistants) to projection capabilities.
The four most common resolutions are:
– SVGA, which is 800 pixels side to side by 600 pixels top to bottom
