Digital projectors can be classified into two different technologies from Texas Instruments DLP and LCD with its various derivatives (LCoS and D-ILA).
DLP (Digital Light Processing)
DLP uses a (DMD Digital Micro-mirror Device) chip consists of thousands of micro mirrors, each of which corresponds to a pixel of the final image. Each of these mirrors can be tilted independently to either reflect light toward the lens or away from the lens to a baffle to absorb light. The form easiest analogy is to think of each replica to be a light that turns on or off. The mirrors can tilt several thousand times per second, so that when a individual mirror is "the" more often than it is "off" we have more light reflected and when "off" more often that "" we have less light reflected. This results in a lighter or darker gray pixel.
More light is reflected color in DMD is – right now – in shades of gray and the next stage is to convert this image to grayscale full color. Among the DMD chip and the array of lens segments is a wheel color filter (red, green and blue in the design simpler). The color wheel rotates rapidly (50 times per second for a single speed wheel into a source of 50 Hz) and the tilt of the mirrors and is programmed to allow light to pass or not pass right through each filter in the wheel rotates, producing a color image.
The "Rainbow" effect The result of this process is that DLP projectors to construct a color image on screen a series of static monochrome image. The rainbow effect – sometimes called color separation – occurs when the eye can detect these monochrome images in parts of the overall picture it produces. The Most people are not susceptible to this problem, but then if you can make a single chip DLP projectors uncomfortable to watch. The problem has eased a bit recently faster development of color wheels with more segments, making the image that is updated more frequently every second.
LCD
LCD (Liquid Crystal on Silicon) is currently the most widely used projection technology in the world. In general the systems used are 3 monochrome LCD panels, one for red, green and blue. The light from the lamp passes through two dichroic mirrors that separate light into its primary colors. Each color shines in a micro-LCD, each pixel can be "in", blocking light, or "off", which allows light through. Light entering passes through a dichroic prism which re-combining red, green and blue to produce a color image, which becomes the projector lens.
The "Chickenwire" or "screen door" Effect
Until very recently people using LCD projectors have been able to see a fixed pattern noise when viewing an image. This is the grid pattern formed by the gaps between the individual pixels. As LCD technology has improved and has increased the resolutions of this device has become ever less of a problem. With high resolution LCD projectors is reduced to a point where they rarely – if ever – seen in normal viewing distance.
D-ILA and LCOS
D-ILA (Direct-Drive Image Light Amplifier) is a development by JVC, and is sometimes referred to as LCoS (Liquid Crystal on Silicon). D-ILA operates a place of transmissive main reflection. In other words, polarized light (red, green and blue) is reflected in D-ILA chip rather than being transmitted through LCD chips. The D-ILA reflectors technique involves laying the pixels in the address selection section and section modulation liquid crystal light in three dimensions. The entire surface except for the section of insulation between the electrodes of pixels, is used as a reflective surface, so an index opening is very high as possible (D-ILA more efficient than other technologies). The main benefit to consumers from D-ILA is the ability to produce high while the output retention of light high contrast without depending on adjustment of the lens iris.
