At ProyectoresOK many clients ask us what they mean and the differences between LCD, DLP, Led and Laser projectors , and which of them is the best projector . To begin with, it should be noted that LCD and DLP are technologies that generate the image of the projectors, while LED and Laser refer to the part that generates the light in the projector.

Differences between LCD and DLP
Which is better?

The 2 main image generation technologies in projectors are:

• English LCD Liquid Crystal Display
  
• DLP stands for Digital Light Processing
  

LCD projectors use a system of 3 LCD panels , one panel for each of the primary colors of light: red, green and blue (RGB in English), which is why you will also find it as 3LCD . A powerful beam of light is divided and sent through mirrors and color filters to the LCD panels. Then the partial images of each color are joined together using prisms, and the complete image comes out through the lens of the projector. The color accuracy of the 3LCD is excellent, so the colorimetry is very good and the LCD gives very realistic colors .

Advantages of LCD projectors:

• Truer Colors : LCDs tend to offer more accurate and vibrant colors, making them ideal for presentations, office and business , professional film and photography, etc.
• Brighter : LCDs are brighter than comparable DLPs, making them ideal for conference rooms and ambient light environments.
• Durability and reliability : LCDs have a longer lifespan than DLP models, and generally break down less.

DLP projectors use a DMD (Digital Micromirror Device) chip , along with a color wheel with 4 or more colored tinted segments, which rolls at high speed thanks to a small motor. It has the basic red, green and blue, but depending on the manufacturer and model of the DLP projector , it also has yellow, cyan, or magenta. A powerful beam of light is passed through one of the segments of the color wheel and is bounced off the DMD chip, which has a matrix with as many micromirrors as there are pixels in the image, and which orients them conveniently according to how it should deflect the light. or project it. This same thing is done for each color and for each frame, at very high speeds indistinguishable to the human eye, in such a way that it is our brain that generates the complete image. Due to its micromirrors, DLP has greater contrast , but also what is known as the 'rainbow effect', as well as its lower color luminosity.

Advantages of DLP projectors:

• Better contrast, in the dark : DLPs tend to offer higher contrast and deeper blacks when projecting in the dark, making them ideal for home theaters and gaming .
• Cheaper : In general, DLPs are cheaper than similar LCDs, so they are a good option for buyers with a low budget.

Differences between LED and Laser
Which is better?

As we said at the beginning, LED and Laser are 2 light generation technologies in projectors. To date, the most economical and widespread way to generate light inside a projector is with a lamp , which burns out every so often (several thousand hours) and must be changed.

A few years ago, LED projectors came out, which are generally smaller devices but have a luminosity VERY lower than lamp projectors, so their use is very limited since they must be used completely in the dark, or make a measurement much smaller screen than would be possible with lamp projectors. Another important drawback of LEDs is that once the LED burns out, the projector is no longer useful, because LED projectors DO NOT have replacement parts .

Luckily, over the years, LED technology improved a lot, until Laser projectors appeared. These new projectors are robust and durable, they use Laser diodes to produce light, and achieve enormous luminosities that can reach 20,000 and even 30,000 lumens (perfect for auditoriums and large rooms ). Although Laser projectors are more expensive than other projectors, the useful life of Laser projectors is much longer: up to 20,000 and 30,000 hours depending on the manufacturer and range. Due to their social commitment to the environment, all manufacturers without exception are moving to this new Laser technology, which is more Sustainable and without harmful substances such as mercury or halides.
