Pico Projectors are becoming a sensation due to their portability. However, many would wonder about how they are constructed. Three different types of technologies are used to make Pico Projectors. These three techniques use different concepts to project content. Choosing the right technology may seem harsh, but we assure you that after reading this your perception will change.

This guide is a simple guide comparing each projector technology. You can seek out your priorities and choose which technology Pico projector suits you the best. Let us start with DLP.

Digital Light Processing (DLP)

DLP uses a white light source to project content. It uses tiny mirrors to control the brightness of each pixel. Also, a color wheel is inserted between white light source and mirrors to control colors of each designated pixel. Nowadays, newer models use DLP chips for the operation.


  1. DLP Projectors can produce high contrast ratio.
  2. DLP Projectors are smaller compared to LCoS projectors.
  3. DLP Projectors have the ability to clear all issues concerning Motion Blur. They are sharper compared to other two.
  4. DLP Projectors have less visible pixels.


  1. DLP Projectors suffer Rainbow effect which can annoy viewers.

Laser Beam Steering (LBS)

With the use of optical concepts, laser beams of three different colors are coalesced. Images are formed because of these three laser beams. Also, they are scanned at faster rates to remove scanline effect. It is more advanced and unlike DLP does not needs a white light source.


  1. LBS Projectors consume less power compared to other two technologies.
  2. LBS Projectors are more compact. Thus, they require less space compared to other two technologies.
  3. LBS Projectors do not suffer from Rainbow effect.


  1. LBS Projectors are costly.
  2. LBS projectors are harmful to human eyes.

Liquid Crystal on Silicon (LCoS)

LCoS is the newest technology out in the market relatively. It is a combination of both DLP and LCD. Liquid crystals are used. With a mirrored backing, a reflective surface is established. Depending on the motion of liquid crystals, the light either passes through them like DLP or is blocked like LCD.


  1. LCoS Projectors have no visible pixels.
  2. LCoS Projectors do not experience Rainbow effect.
  3. LCoS Projectors project richer colors.
  4. LCoS Projectors have high contrast ratio.


  1. LCoS Projectors suffer from convergence errors and motion blur.
  2. LCoS Projectors have low brightness level.
  3. LCoS Projectors’ lamp has a limited life.

Finals Words

Each technology has a different approach towards projecting content. If you want to project content in a dark room then brightness level will not matter however in rooms with light, brightness will play a vital role. Each technology has its fair amount of pros and cons. Depending on the user, you may access conditions of the room where you’ll project content. However, as you are looking forward to buying a Pico Projector, you need to be more specific as you’ll be traveling as well. Choose accordingly!
