LCD vs DLP Projector

Confused in choosing between LCD and DLP projectors? No worries. You have come to the right place.

Of course, both LCD and DLP projectors are very popular on the market. They are both used in a variety of applications, such as for office uses, classrooms, and home theater systems. However, the two types of projectors are not exactly interchangeable. They have each own strengths and weaknesses that make them suitable for different conditions and purposes. See the comparisons between LCD and DLP projectors below.

What are LCD/DLP Projectors?
LCD stands for “liquid crystal display”. LCD projectors are the modern equivalent of slide/overhead projectors. It can be used to display images, videos, and computer displays on a screen. It works by sending light onto mirrors that split the light into three primary colors (red, green, blue). These colors then pass through three separate prisms, and finally get converged by a second prism to be projected on the screen.

On the other hand, DLP stands for “digital light processing”. DLP projectors are different that they use digital micromirror devices (DMD) to produce images. A DMD chip has thousands of tiny mirrors that are designed in a way to represent pixels. Light is sent to these mirrors to reflect a digital imagery to the screen.

Why Choose LCD Projector
The first reason to choose an LCD projector is if you are going to use the device for presenting text often. An LCD projector would produce sharper, crisper text and images. If you want your presentation to be readable from the rearmost seat in a large meeting room, an LCD projector makes a better choice. It can also be a good choice for entertainment purposes because of the rich color dynamics, the quiet operation, and the inexistence of rainbow effect.

Why Choose DLP Projector
However, if you are not going to present text a lot, or if the projector is solely for entertainment purposes, you may want to choose a DLP projector. This is because a DLP projector tends to deliver smoother video and great contrast. You will enjoy real black levels and vibrant, deep colors. It makes films and games appear more vivid. Unfortunately, DLP projectors are slightly noisier when operating, and are prone to the rainbow effect. A good quality DLP projector would have just little rainbow effect.

- Uses prisms and mirrors to separate light into colors- Uses a DMD chip containing thousands of small mirrors to represent pixels
- Better sharpness- Better contrast
- No rainbow effect- May have rainbow effect
- Suitable for presenting text- Suitable for watching films and playing games

LCD projectors are usually preferred when sharpness is considered important, such as when presenting text. However, if you want to get the best contrast and color quality in general, DLP projectors are the way to go. It will make films and games appear even more vivid.
