IMAGING TECHNOLOGIES

All projectors have the same goal: visualization, showcasing an image on a canvas. But not all projectors are the same. Different projectors use different technologies.

How LCD Projectors Work

LCD (Liquid Crystal Display) is a transmissive imaging technology. It means that the three colored beams (red, green and blue) formed by the light source pass through three LCD imagers, one for each primary color. These LCD cells are made out of a number of pixels and contain a liquid crystal layer, which is controlled via local electrical signals.

The signals affect the pixel in the layer and changes the polarization of the light. This change of polarization allows more or less light to pass through the polarizers placed at either side of the LCD module and this then forms a frame of the digital image.

Almost all LCD projectors have a three-chip architecture, which means that after the frames are formed by the polarizers, the three frames, one per color, are then combined into one through a color combination prism, and then projected through the projection lens onto the screen.

How DLP Projectors Work

A DLP (Digital Light Processing) projector, on the other hand, directs the red, green and blue light to one or more Digital Micromirror Devices (DMDs). As its name suggests, a DMD is covered with millions of microscopic mirrors and each of those tiny mirrors corresponds to the individual pixels of the image.

While projecting the image, the micro-mirrors alternate between their on and off positions. This means they change their orientation to either reflect the light towards the projector’s lens and onto the projection screen or the light is reflected away from the main lens into a light-absorbing area. It’s why DLP is called a reflective imaging technology. The mirrors’ ultrafast continuous on/off alternation defines the brightness and color of the corresponding pixels and forms the projected image.

In a single-chip DLP projector, each primary color is directed to the imager sequentially, and the image for each color is formed separately. Because it happens so fast our brain is able to blend the images into a full-color result. 3DLP, like the 3LCD projectors, use three imagers which will form the red, green and blue image simultaneously.
